Advertising endorser is one of promotional strategies which are often seen in daily life.Its main purpose is to use a famous, professional or attractive endorser to grab consumers’ attention in a short period of time, in order to increase the effectiveness of the advertisement. It is important for endorsers to achieve the object of communication with consumers. Research finds that advertisements with a reliable endorser could attract consumers’ attention, raise brand awareness, and build uniq ue brand image (Zajonc and Markus,1982). If a business can select product endorser carefully to match up with product attributes, it can produce a model effect to a brand.Therefore, understanding how consumers perceived product endorsers, and knowing which types of endorsers would create the best effect to the advertisement is significant for marketers. This research will mainly focus to research on skin-care products endorsers by the measure of their credibility, and how they influence the advertising effectiveness. 1. 1 Background to Topic 1. 2 Fashion Field and Skin care products Fashion is a business of wide variety: from typical apparel business to beauty and health care products. The fashion field is highly segmented and overlaps with other fields, especially with the cosmetics and skin care roducts. Some of the household fashion brand names may not definitely correspond to the apparel business but other kinds of products. One of the characteristic of the fashion field is that it is constantly re-forming in strategic cooperation and alliances. Fashion companies such as Fendi, Polo Ralph Lauren, Kenzo, and Louis Vuitton are practicing the strategic integration. For example, Christian Dior is part of LVMH limited, which is the largest luxury company and group in the world, also include cosmetics products and skin care products in their brands.The structure of the fashion field is obscured mainly by licensing and franchising strategy; fashion companies may manufacture products which belong to a particular line in the structure. For example, Donna Karan International licenses its name to Estee Lauder, and Polo Ralph Lauren licenses the fragrances and skin-care products to L'Oreal. LVMH, Chanel and Prada have their own brand name lines in skin care products. Some skin care brands may belong to the same fashion organization, though the brands are in totally different names and management structure.The identity of the famous fashion company would give their pro ducts a competitive advantage, which are the symbolic exchange and the commodity exchange. It would establish, maintain or strengthen a brand identity. Skin-care products advertisements with endorsers is not hard to be seen in different media, household skin-product brands such as L’oreal, Neutrogena or Shiseido has spent numerous money on hiring different endorsers for the brand and new products. Generally, two types of advertisement endorsers have been mainly been used in these advertisements – celebrity and expert.There are number of studies can be found that how different endorsers influence the consumers in different fields. However, there are few studies to focus only at the relationship of different endorsers and skin care product brand. Skin care product is a special category compared with other different products. It is considered both hedonic and utilitarian product. There are different categories of skin care product, such as the aqua cream, hand cream or UV -protection cream. Therefore, the skin-care product is both attractive-related and health-related.Customer needs adequate information and sufficient expertise prove and advice for them to purchase these products. Research shows that the extent of audience-perceived skills and knowledge of the endorser in the source expertise would make positive influence to the advertisement, such as the skin care experts are critical to influence in advertising (Chawla,Dave, and Barr 1994); however, some research suggest the sources characteristic attractiveness, such as celebrities are important to persuasion (Kamins and Gupta 1994; Patzer 1983).Although the perspectives are diverse, source credibility which combined of both attractiveness and expertise is critical to make influence to advertisements towards the audience. Skin care product marketers would typically employ a product endorser with high credibility to advertise the product. Therefore, it is significant for marketers to know which typ e of endorsers and how endorsers would make an advertisement worthwhile and effective, in addition to this, whom could make good communication with customers.The purpose of the study is to explore whether endorser credibility has a positive effect on advertising effectiveness in the skin care product. This study would also explore which type of endorser in the field of skincare products would make more influence, and how they influence the consumers. Chapter 2—- Literature review 2. 1Advertising Endorser According to Federal Trade Commission (FTC), any advertising message reflects spokespersons' or endorsers' opinion, belief, character, and experience that make consumers believe is called endorsement.Advertising endorsers are often seen on TV, newspaper, magazine, or direct mail advertisements in daily life. Using the endorsers' popularity, it could present the benefits of the endorsed product and make consumers produce reliability on the product. (McCracken,1989) Using adver tising endorser to promote a product is a very popular marketing strategy. Researchers also found that the reliability of advertising spokespersons is one of critical factors to influence purchase intention, and the higher the reliability is, the higher the positive advertising and brand attitudes are (Laffery ; Goldsmith, 1999).An advertisement can catch consumers’ attention and increase brand awareness (McCracken, 1989), and transfer consumers’ feelings onto the product and produce a good impression (Biswas et al. , 2006). If spokespersons can express a positive attitude on the advertised product, it will create an intensive preference to consumers and connect the product with the spokespersons (Chen ;Chang, 2001). Study suggested that with a successful endorsement, the recall of product information and brand recognition would be enhanced, it would positive influences the attitude towards the advertisement and products. Liu et al, 2007) Different research proposed fo ur main types of advertising endorsers including celebrities, experts, CEO and typical consumers to test the effectiveness of communication between the endorsers and consumers through advertisement (Freiden, 1984; Wang, 2002). The outfit of the endorser is suggested to create positive attitude toward the consumers (Chaiken, 1979). McGuire (1985) also suggested that endorser which is familiar and likable towards the audience may bring persuasiveness to the advertisement. 2. 1. 1Celebrity EndorserSchiffman and Kanuk (2007) defined celebrities to public and famous figures. Celebrity commonly has a linkage with the source attractiveness. Research has found that there is a linkage between the celebrity attractiveness and attitude changes toward advertisements (Chaiken 1979; Caballero and Pride, 1984). Companies usually use celebrity to be the endorser of product in order to increase the popularity or attraction, making audience to have a positive attitude toward endorsed products, the br and and the advertisement. Research supported the celebrity endorser is suitable for different types of products.It is generally shows that celebrity endorser make positive contribution in different aspects like brand awareness (Till 1998), brand recall (Friedman 1979), attitude toward the advertisement [Kamins 1989; Frieden 1984; Tripp, Jensen,and Carlson 1994), and also purchase intention (Ohanian, 1991). Research also shows that celebrity endorser would generate positive attitude towards brand recall, attitude towards the advertisement, and also purchase intention (Wang 2002). Celebrity with high expertise tends to have higher level of sources believability and trustworthiness. Buhr, Simpson, and Pryor 1987). Studies found that celebrity endorser would be perceived higher values for likeability attribute by the consumer, comparing to an expert, CEO or customer endorsers (Freiden, 1984). However, in the same research, it did not show that celebrity endorsers have a significant adv antage when compared to other types of endorsers in the measure of expertise, believability, product quality and trustworthiness. Celebrity endorser would generally create a positive perception to consumers in sources attractiveness in terms of credibility perceptions.Researchers have found that celebrity endorsers have higher credibility to make the product be more desirable and also higher the image of the product quality; Consumers are associated with endorsers’ image when using the product while the endorsers’ image has been transferred to the product. (Ronald E. Goldsmith, Barbara A. Lafferty and Stephen J. Newell, 2000) Research also suggest that celebrity endorsement can increase brand and product recall (Clark and Horstman, 2003). 2. 1. 2 Expert Endorser Expert endorser is perceived as a person who has extensive skill or knowledge in a particular field.Expertise is the extent of the communication source which has relevant knowledge and skills. The trustworthine ss attribute is an significant source for the expert endorsers, which makes the consumers to have a perception that the advertisement is believable. (Hovland, Janis, and Kelley,1953). Hass (1981) suggests that the expert endorsers have an advantage on source credibility in terms of the expertise and trustworthiness. Research suggests that endorser who has higher level in expertise or trustworthiness, would be more effective when compared to low-expertise sources (Hass 1981; Dholakia 1978).Research also finds that expert endorsers would be more persuasive when compared to the endorsers who have less expertise in the persuasion theory. (Ohanian 1990; Stemthal, Phillips, and Dholakia 1978). The degree of influence of the expert endorser is moderated by variables such as message comprehension (Ratneshwar and Chaiken 1991), placement of the expert source in relation to the message arguments, (Homer and Kahle 1990; Stemthal, Dholakia, and Leavitt 1978), and fit between the expert source a nd the product (Till and Busier 2000).An endorsement from a credible or expert endorser would influence the perspective, also the consumers’ behavior and attitudes (Belch and Belch 2004, p. 169). The receiver is motivated to have a positive and objective sense toward the products and brand when the endorser is an expert, since the audiences believe the message from the endorser is accurate and positive. Till and Busier (1998, 2000) manipulated the expertise of a fictitious person and the fit of the product, the result shows using expertise would create a significant positive relationship towards the brand attitude and purchase intentions.The research shows expertise source is significant when compared to the attractiveness source in different advertisements and products. 2. 2Endorser Credibility According to Ohanian (1990), endorser credibility can be defined as â€Å"as a communicator's positive characteristics that affect the receiver's acceptance of a message†. It i s also a way that can enhance the message of an advertisement. (Anderson, 1970) Dimensions can be found in the previous studies of endorser credibility.Typically, endorsers’ credibility can be separated as three dimensions: trustworthiness, attractiveness, and expertise (e. g. , Homer and Kahle 1990; Ohanian 1990, 1991; Stemthal, Dholakia, and Leavitt 1978). The credibility would show how effective of an endorser in terms of the personal attributes towards the consumers. Goldsmith, Lafferty, and Newell (2000) found that endorser credibility positively influence the attitudes toward the advertisement, and also brand attitude. A high credibility of an endorser is considered significant in influence acceptance.A consumer is more likely to accept the content of the advertisements with a credible endorser (Sternthal, Phillips, and Dholakia 1978). Danwshvary and Schwer (2000) also suggest that in an advertisement with a high credible endorser, purchase intention would be positively affected. According to Khatri(2006) , high credible endorser would also enhance the recall of the product. Research found that higher levels of endorsers’ credibility would have a significant association with attitudes toward the advertisement and purchase intention (Craig and McCann, 1978; Woodside and Davenport, 1974).The dimensions of attractiveness and expertise have generated additional interest to determine how these attributes in an endorser individually enhance advertising effectiveness (e. g. , Homer and Kahle 1990; Kamins 1990; Maddux and Rogers 1980; Patzer 1983; Till and Busier 1998, 2000). 2. 2. 1Trustworthiness Trustworthiness is the level of consumers’ trust toward the endorser and advertising message (Hovland et al. 1953). It also means the general believability of an endorser. Research has suggested the trustworthiness of the endorser would affect the advertising effectiveness.Miller and Baseheart (1969) found that when the endorser was perceived to b e trustworthy, the advertisement would be more effective to influence consumers’ attitudes. McCinnies and Ward (1980) find that the expertise and trustworthiness would influence endorsers’ credibility and persuasiveness. They indicated that the endorser with both expert and trustworthy would generate the opinion change of consumers. Trustworthiness moreover refers to the honesty, believability and integrity of an endorser (Erdogan 1999).Therefore, honesty is in the trustworthiness attribute in this study. 2. 2. 2Expertise Expertise is one of the fundamental dimensions of source credibility and is the knowledge sources are perceived to possess about the product they are endorsing (Homer and Kahle 1990; Ohanian 1990). Recent studies on source expertise indicates that the expertise attribute has a positive influence on attitude change (Maddux and Rogers 1980; Till and Busier 1998, 2000) and purchase intention (Till and Busier 2000). 2. 2. 3 AttractivenessIn terms of attra ctiveness, it represents that advertising endorsers can catch consumers’ attention to a product (Ohania, 1990; Miciak ; Shanklin, 1994; Goldsmith, Laffery, ; Newell, 2000). Research shows that the marketers prefer to use attractive endorser in order to gain the likability and positive attitude toward the advertisement. Some of the research may group attractiveness attributes in source attractiveness itself, however, attractiveness can also be as an attribute of source credibility in advertisments (McCracken, 1989; Ohanian, 1990).In the research of Maddux and Rogers (1980), likability is considered to be a test variable of attractiveness attribute in endorser credibility. Therefore, likability would also be tested as attractiveness variable in the study, it is employed as the measure of homological validity of attractiveness. Advertising Effectiveness Generally, advertising effectiveness is the attributes of brand attitude, attitude towards the advertisement and purchase inten tion attributes. (Gurel Atay, Eda, 2001; Friedman, Hershey H, 1976; David Strutton, 2008)Numerous researches have proved the direct and significant relationship of brand attitude, attitude towards the advertisement and purchase intention attributes. (e. g. , Goldsmith et al. 1999; 2000; 2002; Goldberg, et al, 1990; Mitchell et al. 1981; Mackenzie, Lutz, and Belch, 1986). However, research also can be found to group these three variables together in order to test a more macro view towards the effectiveness of the advertisement. (Gurel Atay, Eda, 2001; Friedman, Hershey H, 1976; David Strutton, 2008) 2. 5 Purchase IntentionAccording to Shamdasani (2001), purchase intention can be defined as the possibility of a customer buying a product or making a recommendation for product. ) It is also a process of the demand for product information, purchasing, evaluation, consumption, and disposal of a product or service. Purchase intentions also means the choice that a consumer would probably ma ke in future course of action. (Bagozzi,1983). According to Fishbein and Ajzen model, higher purchase intention will lead higher purchase willingness. According to Zeithamal (1988), perceived value will influence purchase intention. . 6 Brand Attitude Brand Attitude can be defined as evaluation of the brand from the consumer. It may consist an emotional motivation toward a brand and its product. The motivation could be cognitive or logical toward the particular brand. In recent researches, it has proved that using of endorsers credibility has a positive influence on brand attitudes of the consumers (Seno and Lukas, 2005). Agarwal and Malhotra (2005) have also defined that brand attitude is a general evaluative judgment of a brand. It contains the process of the brand product, reputation and the benefits. 2. Attitude towards advertisement Attitudes toward the ads can be generally defined as a â€Å"predisposition to respond in a favorable or unfavorable manner to a particular advert ising stimulus during a particular exposure situation† (MacKenzie, Lutz and Belch, 1986). Attitudes toward the ads would contain affective reactions and evaluations. (Baker and Lutz, 2000). Research shows that attitudes toward the ads are influenced by a process set of brand or non-brand. (Biehal, Stephen and Curlo, 1992; Hastak and Olson, 1989; Madden, Allen and Twible, 1988; Gardner, 1985; Homer, 1990). 2. 8 Product Match-up HypothesisProduct Match-up Hypothesis can be defined as the match-up theory between an endorser’s and a product’s attributes. McCracken (1989) and Kahle (1985) suggest the celebrity endorser create better inherent match and congruency effect than other types of endorsers by having higher level of attractiveness. Researches based on the matchup hypothesis find that attractiveness is a significant determinant of advertising effectiveness. (Kahle and Homer, 1985; Till and Busler, 1998) suggests that its importance is limited by the degree to w hich attractiveness â€Å"fits† well with the advertised product (e. . Kamins,1990). The product match-up hypothesis is focus on product-endorser fit based on endorser attractiveness. Research suggests that the attractiveness of a celebrity endorser is more favorable attitudes to related the product which is attractiveness-related . Product match- up is the congruence between endorsers and product. The match-up hypothesis (e. g. Kamins, 1990) suggests that endorsers are more effective there is a â€Å"fit† between the advertising endorser and the endorsed product. 2. 4 Information ProcessingAccording to Kahle ; Homer (1985), consumer usually sees the information as relevance when it satisfies their need. The ELM is a persuasion model to predict the influence information process of the advertisement of different types of endorser. (Petty ; Cacioppo, 1981a, 1986a, 1986b) suggests that there are two route, the central route and peripheral route, whereas the peripheral rou te is more likely to prove that endorser relationship with the information processing of the advertisement. ELM posits that a source cue does not serve as a simple acceptance or ejection cue but may be considered together with all other information in the recipients attempt to assess the merits of the arguments and the advocacy. Studies have found that endorsers’ credibility has a significant relationship toward ELM and information processing of the advertisement (Homer ; Kahle, 1990; Petty ; Cacioppo, 1981b, 1986a, 1986b; Petty et al. , 1991). Mehta (1994) also found that the celebrity endorser would influence consumers to have more thoughts about the endorsers, however, and the fewer toward the product and brand.A different type of endorser such as experts would influence consumers to generate fewer thoughts about the endorser but led to more thoughts about the brand and product featured Chapter 3 : Research Hypothesis and Conceptual Framework 3. 1Introduction According to research purposes and literature reviews, the study proposes the research frame as shown in Figure 1. 3. 2 Research Hypothesis H1: Endorser credibility would significantly affect advertisement effectiveness Celebrity vs ExpertH2: Celebrity endorser has a better performance in the general measure of â€Å"Endorser Credibility† than expert endorser H3: Celebrity endorsers has a better performance in the measure of â€Å"attractiveness† attributes than expert endorser H4: Expert endorser has a better performance in the measure of â€Å"trustworthiness† attributes than celebrity endorser H5: Expert endorser has a better performance in the measure of â€Å"expertise† attributes than celebrity endorser Product Match-UpH6: Endorser credibility would significantly affect product match-up hypothesis H7: Celebrity endorser would generate a better match up effect towards the product than expert endorser Information Process H8: Endorser credibility would significantl y affect information process of the advertisement H9: Consumer is more likely to process the information of the advertisement when the endorser is an expert, than a celebrity H10: â€Å"Product match up† and â€Å"Information Process† would positively moderate the relationship between endorser credibility and advertising effectiveness Conceptual Framework Chapter 4:Methodology . 1 Questionnaire Design In order to assess the relative advertisement effectiveness between celebrity and expert endorsers, two advertising executions were tested across print advertisements for two different type skin-care products: an aqua cream and hand cream with body emulsion. A celebrity advertisement and an expert advertisement represented each product. In this research, the celebrity is person who is publicly recognized and could direct and communicate to consumers by their reputation in the advertisement. On the other hand, an expert is a person represents expertise of the product and s kin care.The experts who appeared in the advertisement sample has been noted a â€Å"professional doctor of skin care† and â€Å"dermatologist†. They have no public notoriety but appear in an advertisement for representing the authority of the product. The samples are based on real print advertisements (see appendix 1 and 2), in order to increase the authentication. Famous Hong Kong singer Kandy, a member of the band Sugar Club, is the endorser of the aqua cream advertisement; on the other hand, famous model Gaile is selected as endorser of the hand cream and body emulsion cream.The expert endorser is from the real print advertisement of Neutrogena, however, for the expert endorser, we created a fictitious endorser, as the names and their scope of profession have changed to fit this sample research. The use of a created endorser offers a benefit of controlling the experiment. Although endorsers are usually well-known, there can be a significant amount of variation in s ubjects’ knowledge and attitude toward any given endorser.By using a created endorser, we minimize the amount of variation in subjects’ knowledge thereby strengthening the statistical power of the analysis. In order to avoid brand perception of the audience, the products in the sample advertisements has used the brand name â€Å"Super† which does exist in the reality market, instead of the real brand names of the products. The research selected two categories of skin care products: aqua defense cream and hand cream and body emulsion. In order to minimize brand familiarity effects, a fictitious brand name, â€Å"super† was used. 4. 1. Questionnaire Structure and Details The questionnaire used for this study consisted of five parts targeting different aspects of information about consumer’s attitude on different endorsers’ advertisement and the influence of advertisement effectiveness. The aim of this study was stated in the beginning and foll owed by a notes explaining the terminologies used in the questionnaire. For the scale of data measurement, five-point Likert scales were used in the questions of part A and part B sections for measuring the attitudes and quantifies the opinion of the consumers.Likert scale is a set of statements that ask respondents to express their level of agreement or disagreement of a five-point scale (Churchill, 2005). For the remaining parts, they were consisted of single and multiple selections of answer. 1=Strongly Disagree| 2=Disagree| 3=Neutral| 4=Agree| 5=Strongly Agree| 4. 1. 3. 1 Part A of the Questionnaire The first part of the questionnaire aimed to obtaining data about the respondents’ purchase experience on skin care products as well as their knowledge and experience about current practice of different types of endorsers’ advertisement, the source of information is also included.The respondents are required to indicate how they receive the information about endorsement and which type(s) of endorsers were familiar with them. 4. 1. 3. 2 Part B of the Questionnaire This part is aimed to focus on the aqua cream advertisement, which represents the skin care product type which is attractive-related. Two â€Å"super† aqua cream product print advertisements were shown in this part. This advertisement is a real advertisement from the brand â€Å"Garnier†. This first advertisement is endorsed by famous Hong Kong singer Kandy, a member of the band Sugar Club, who is the actual endorser for â€Å"Garnier†.The second one is endorsed by a fictitious expert endorser, named as Albert Li, noted as a â€Å"professional doctor of skin care†. The context of the advertisement contains the product features of the cream, and comparison with other brands in order to show the effect of the cream. The content of two advertisements are exactly the same, however, only the endorser is changed in order to test the effect of these two types of endor sers. There are 17 questions for each advertisements, it is a set of statements regarding the attributes of the endorsers, and the attributes of the advertisement.The attributes were based from the source credibility models, product match-up hypothesis, and advertising effectiveness which were suggested by previous studies regarding advertisements with endorsers. 4. 1. 3. 3 Part C of the Questionnaire This part is aimed to focus on the hand cream and boy emulsion advertisement, which represents the skin care product type which is health-related. Two â€Å"super† aqua cream product print advertisements were shown in this part. This advertisement is a real advertisement from the brand â€Å"Neutrogena†.This first advertisement is endorsed by famous Hong Kong model Gaile, who is the ex-wife of Hong Kong famous singer Leon Lai. The second one is endorsed by an expert endorser, named as Robert Kwon, noted as a â€Å"dermatologist†, who is the actual endorser for â₠¬Å"Neutrogena†, however, in the actual advertisement, the endorser is a a regional director of professional marketing. The context of the advertisement mainly contains the product features of the hand cream and the body emulsion. The content of two advertisements are exactly the same, however, only the endorser is changed in order to test the effect of these two types of endorsers.The structure of the questions is the same as part B section. 4. 1. 3. 4 Part D of the Questionnaire This was the final section of the questionnaire, four questions were asked in order to find out the demographic information of the respondents. Respondents were required to provide their gender, age, educational level and income. The information would be used to test the difference response from different demographic group, mainly the educational level and income, since the target group is selected to be young female adults in generation Y. 4. 2 Questions Analysis and Discussion Guide The survey is se t in two main sections.One scale is used to assess endorser credibility, including the aspect of attractiveness, expertise, image, likeability and trustworthiness. The survey also included questions related to the advertising effectiveness in aspects of brand attitude, attitude toward the advertisement and purchase intention. Message processing and product and endorser match- up issues would also be included in the questions. The questions were grouped in order to analysis the relations between variables. Each respondent was shown two print advertisements of different skin care product and were asked to complete the questionnaire.In each case respondents were exposed to advertisements for of two products including a celebrity, and an expert endorser. 3. 2. 1 Testing Credibility of Endorsers To test the credibility of endorsers, the attributes by previous studies are adopted. The attributes would be attractiveness (DeSarbo and Harshman 1985), trustworthiness (DeSarbo and Harshman 198 5;), expertise (DeSarbo and Harshman 1985; Simpson and Kahler 1980-81; Wynn 1987), likability (DeSarbo and Harshman 1985) and believability (Simpson and Kahler 1980-81; Wynn 1987).In the questionnaire, 5 statements would refer to 5 different attributes from the source credibility model. â€Å"The endorser is attractive† is to test the attractiveness variable, â€Å"The endorser is trustworthy† is to test the trustworthiness variable, â€Å"The endorser is professional† is to test the expertise variable, â€Å"The endorser is honest† is to test the believability variable and â€Å"The endorser's image is positive† is to test the likability variable. These 5 attributes would be grouped to be the â€Å"Credibility† level of each endorser in the followed analysis. 4. 2. Testing the Product Match-Up Hypothesis As the product match-up hypothesis is not the main focus of the research, only two statements in the questionnaire was asked to test the h ypothesis, â€Å"The endorser in the advertisement makes good match with the product† and â€Å"The endorser helps to understand the function of the product† was asked to figured out if the audience considered the endorsers made good match with the product and helped them to understand the function of the products. The result of this hypothesis would be tested if it is a factor to influence the advertising effectiveness. . 2. 3 Testing Advertisement Message Process One statement was asked to understand if the respondents would read the content message of the advertisement, besides the endorsers’ image. The result of this part would be analyzed with if different endorsers have influence for the audience to process the image, and this question would also analyzed with the advertising effectiveness attributes to see if there is a relation between audience process the advertisement message and the effectiveness of the advertisement. . 2. 4 Testing Advertising Effect iveness Three attributes were combined to consider the effectiveness of the advertisement: â€Å"Brand attitude†, â€Å"Attitude towards the Advertisements† and â€Å"Purchase Intention†. 4 statements were set to test the brand attitude towards the advertisements, which were â€Å"The endorser enhances my ability to recognize the brand†, â€Å"This advertisement projects a good brand image†, â€Å"This advertisement helps to recall the product features† and â€Å"This advertisement helps to recall the brand†.Another 4 statements were also set to test the attitude towards the advertisements, which were â€Å"This advertisement projects a sense of good quality towards the product†, â€Å"This advertisement projects a pleasant feeling†, â€Å"This advertisement is reliable† and â€Å"This advertisement is persuasive†. In addition, 1 statement was set to test the purchase intention of the audience towards the a dvertisement and endorsed product, which was â€Å"This advertisement increases my intention to purchase the product†. These three attributes would be the dependent variables to combine as â€Å"advertising effectiveness†.They would be analyzed with the credibility of different endorsers, product match-up hypothesis and advertisement message process. 4. 3 Research Objective The quantitative survey is focused on the young female adults as the interviewees, which is in the demographic of generation Y. The age range of young is between 18and 30 years old, which are mostly in the student segment. In this group of people, they tend to be attracted by ‘advertising’, ‘brand’, and ‘fashion’. They are more familiar to celebrities and advertising from different types of media.In the meanwhile, they have more comprehensive understanding and relative matured self-norms. 4. 4 Pilot Test A pilot test was done in advance of distributing of the q uestionnaire for gathering information, this is to ensure the format and design of the questionnaire were effective and capable of obtaining required information for the researching objectives. Another important function of the pilot test to this study is that the sample population was asked to rank a set of selection criteria of celebrity and expert endorsers in order to refining the selection attributes for a more efficient analysis. 3 questionnaires were distributed and 20 questionnaires were returned with comments on the questionnaire design. Some amendment and adjustment was made to the questionnaire after reviewing the feedback of the sample population, the modification included adjusting the layout of the questions, use of question’s wordings, segmentation of demographic data of respondents, and elimination of repeated questions. 4. 5 Distribution of the questionnaire Data were collected from a total of 203 respondents on the internet survey instrument.The survey is sp read by social network requests and e-mail request, which ensures that the target group of people could reach to the survey, and avoid people who is not in the target group doing the survey. The internet-based survey can also obtain the response from more population within a short period of time by not restricting by geographical constrain. 4. 6 Research process and design The research process follows the structure in figure. First, the problem of the research is fomulated, which is the comparasion of expert and celebrity endorsers towards the credibility and advertising effectiveness.Then, an exploatory research is at the second procedure, by reviewing literature. Research framework and data collection methods are determinated at step three and step four. The following is designing samples and collecting data by internet-based survey. The data will be analysed to be the results of the research. Suggestions and recommendations would be made in the references of the results. Chapter 5: Result and Analysis Respondents Profile In the following section, basic demographic data of the respondents, including age, gender, education level, occupation and personal monthly income level, were reported.To be more specific, these descriptive data were summarized and presented with pie charts. Gender of Respondents Since the target respondent in this study is female, the questionnaire is mainly distributed to female interviewee.

It provides the coeffici ent of inter-item correlations and measured the internal consistency of various items. Referring to Cohen et al. 2007), the reliability level was marginally acceptable at 0. 6 and highly reliable at 0. 8 or above, while according to Pallant (2007), the Cronbach’s alpha value above 0. 7 is considered acceptable and preferable when the values exceed 0. 8. Ohanian’s (1990) scale was used to assess the celebrity endorsers’ credibility. Items were chosen according to the item reliability of the scale. To measure credibility, the dependent variables â€Å"attractiveness†, â€Å"trustworthiness†, â€Å"expertise†, â€Å"likeability†, and â€Å"believability† were selected. In section A, the celebrity endorser Kandy has a Cronbach’s ? f . 962 towards the credibility. The Cronbach’s ? for the expert endorsers’ credibility is . 860 in section A. In section B, the celebrity endorser Gaile has a Cronbach’s ? of . 869 towards the credibility. The Cronbach’s ? for the expert endorsers’ credibility is . 860 in section B Based on studies addressing advertising effectiveness (Biehal, Stephens and Curlo, 1992;Craciun, Stephens and Madden, 2002; Gresham and Shimp, 1985; Spears and Singh,2004), brand attitude, attitude towards the advertisement and purchase intention were used to assess the effectiveness. The Cronbach’s ? or the brand attitude in section A are . 893 and . 824 The Cronbach’s ? for the attitude towards the brand in section A are . 806 and . 793. The Cronbach’s ? for the brand attitude in section B are . 831 and . 712. The Cronbach’s ? for the attitude towards the brand in section B are . 925 and . 908. Referring to Cohen et al. (2007), the reliability level was marginally acceptable at 0. 6 and highly reliable at 0. 8 or above, therefore, the items to be measured in this study is highly reliable. 4. 3 Endorser Credibility and Advertisement E ffectiveness IntroductionIn this study, in order to test H1: Credibility of endorsers significantly affects advertisement effectiveness, linear regression analysis is adopted in testing the relationship of dependent variable (Y), advertising effectiveness, to relate the independent variables(X), which is the endorsers’ credibility, for the prediction. The measures of endorser’s credibility consisted of 5 attributes, which are trustworthiness, expertise, believability, attractiveness and honesty. Meanwhile, advertising effectiveness contained 3 attributes, including brand attitude, attitude towards the advertisement and purchase intention.The attributes of credibility and advertising effectiveness had combined as the mean score in the analysis. In the following table, Credibility1 of celebrity endorser Kandy in part A; Credibility2 represents the computed results of expert endorser Albert in part A; Credibility3 represents the computed results of celebrity endorser Gail e in part B; Credibility4 represents the computed results of expert endorser Robert in part B. â€Å"EndorserAdeffectiveness† represents combined mean score of all endorsers’ advertising effectiveness. Coefficient of Determination R squareMujis (2004) had provided a guide to assess how well a developed model fit the data. The table would give a clearer interpretation of Mujis suggestion. 0. 5| Strong Fit| Result of Endorser Credibility and Advertisement Effectiveness Model Summary| Model| R| R Square| Adjusted R Square| Std. Error of the Estimate| | 1| . 756a| . 572| . 569| . 24445| a. Predictors: (Constant), Credibility1, Credibility2 Credibility3, Credibility4| To test the correlation of the endorser credibility and their advertising effectiveness, the coefficient of determination r2 is used.It is a statistical term that tells us how well one variable is at predicting another. Since the study is a small scale research, using adjusted R square would give a more accura te result. (Mujis ,2004). The dependent variable â€Å"EndorserAdeffectiveness† is the combined mean score of all endorsers’ advertising effectiveness, and the independent variable â€Å"Credibility 1† to â€Å" Credibility 4† is the mean score of celebrity and expert endorsers in part A and part B. In the table, the R square is 0. 572 and the adjusted R square is 0. 569, with the standard error of 0. 24445.As the adjusted R square is 0. 569, it indicated that the credibility of endorser explains 56. 9% of advertising effectiveness. According to the Mujis, when adjusted R square is >0. 5, it shows a strong fit of the model. Therefore, the correlation between endorsers’ credibility and advertising effectiveness is strong.
