Chapter 2 Literature Review

2.3 Hedonic Value

Hedonic value, defined as consumption behaviors that relate to fantasy, happiness, sensuality, and

enjoyment (Hirschman and Holbrook, 1982), is an overall assessment of experiential benefits.

Compared with conventional utilitarian shopping values, the merit of hedonic value is experiential

and emotional. The reason why hedonic consumers do shopping is not for physical objective but for

the shopping process instead. Research concerning hedonic motivation becomes more popular lies in

two reasons. One is the obvious value that appeals to consumers to patronage the website, the other

is the fact that hedonic value is the extension of utilitarian value and these two values seem to

become crucial factors in keeping competitive advantage (Parsons, 2002).

Numerous studies used to adopt hedonic value dimensions to discuss in-store shopping.

Nevertheless, there are more and more research using hedonic value dimensions to explore online

shopping. Except for the freedom to search, hedonic value is also an important element. Mathwick et

al. (2001) discusses the experiential value of online shopping, and enjoyment and aesthetics should

be viewed as hedonic value. Kim and Shim (2002) propose that consumers go on line is not only for

information and products, but also for emotional satisfaction. Hedonic online shoppers are

accustomed to active pursuit while online. They often browse website, search for new items and

12

download updated information, actually they are bathed in the process of enjoyment. In addition,

hedonic shoppers were attracted to online environment because the virtual community offers social

relationship (Wolfinbarger and Gilly, 2001).

According to previous studies, it appears that hedonic values play important roles in online

shopping (Pui et al., 2007). Childers et al. (2001) indicated that hedonic orientations are strong

predictors of attitudes toward online shopping. Hedonic shopping values were positively related to

attitude toward online shopping and intentions to shop online (Menon and Kahn, 2002). In view of

the above, it is plausible to expect a positive relationship between hedonic values and attitude toward

online shopping. It is thus hypothesized that:

H14: Adventure is positively related to attitude toward online shopping.

H15: Sociality is positively related to attitude toward online shopping.

2.4 Main effects of gender on online shopping values

This study categorizes utilitarian value into convenience, availability of information and lack of

sociality, they are detailed as follows.

13

2.4.1 Convenience

Convenience is defined as time savings and effort savings, including physical and mental effort.

Convenience is a crucial attribute for consumers when shopping online.

Shopping online makes it easy for consumers to locate merchants, find items, and procure offerings

(Balasubramanian, 1997). Wolfinbarger and Gilly (2001) mentioned that internet shopping provides

a more comfortable and convenient shopping environment. Consumers do not have to leave their

home and they can also browse for items by category or online store. Schaffer (2000) argued that a

convenient internet shopping provides a short response time and minimizes customer effort.

Swaminathan et al. (1999) reported that male internet buyers were more convenience oriented

and less motivated by social interaction than women Internet buyers. Alreck and Settle (2002)

indicated that women have more positive attitudes toward shopping, while men prefer shopping via

internet (Alreck and Settle, 2002). Hence,

H21: Men have higher scores on convenience than women.

2.4.2 Information availability

Bakos (1997) postulated that the internet includes abundant public information resources that can

be easily collected. For online shoppers, internet is the most efficient means to get related

14

information. The internet as a medium facilitates searching both product specifications and price

information. Price is an important reference and adolescent consumers often compare price between

multiple websites.

Women tend to be more sensitive to related information online than men when making

judgments (Meyers-Levy and Sternthal, 1991), bringing out subsequent purchase attitudes and

intentions presented by men and women to differ. In other words, females make greater use of cues

than males. Cleveland et al. (2003) find that when executing consumption women seek more

information than men. Hence,

H22: Women have higher scores on information availability than men.

2.4.3 Lack of sociality

Wolfinbarger and Gilly (2001) indicate that online shopping enables people to execute a

transaction without contacting others, and online buyers have more freedom and control over the

transaction. One advantage of online shopping is that online buyers can decide to buy or not and the

transaction is under their control. In addition, while shopping online, it turns out that people can

avoid social interaction and crowded environment.

15

Since men and women differ significantly in conventional buying motivations, we seem to

assume that this would also be the case on the internet purchasing. Swaminathan et al. (1999)

reported that male internet buyers were less motivated by social interaction than women Internet

buyers. Compared with men, women tend to enjoy shopping (Alreck and Settle, 2002), and they can

have more social interactions in the process of consumption. Computer-mediated shopping does not

offer women much social contact. Hence,

H23: Men have higher scores on lack of sociality than women.

Based on Pui et al. (2007), the hedonic values in this study comprise adventure and sociality, they are

detailed as follows.

2.4.4 Adventure

Adventure refers to the fact that shopping can bring stimulation and excitement, meaning that

consumers can run across novelty and interesting affairs in the process of fantastic shopping

(Westbrook and Black, 1985). Experienced consumers are inclined to view the shopping experience

as thrills, excitement and amazement. Babin et al. (1994) regard adventurous aspect of shopping as

an element that may produce hedonic shopping value. Sherry (1990) addresses that in the shopping

process shoppers pay more attention to sensual satisfaction rather than the product itself.

16

Women stress emotional and psychological involvement in the whole shopping and buying

process, while men emphasize efficiency and convenience in obtaining buying outcomes (Dittmar et

al., 2004). In other words, the added value attached to shopping process may play a much more

prominent role for female consumers, whereas male consumers’ primary concerns are to get the

product only, shopping process may function as nothing meaningful for men. Hence,

H24: Women have higher scores on adventure than men.

2.4.5 Sociality

Sociality, grounded in McGuire’s (1974) collection of affiliation theories of human motivation,

suggesting that people put emphasis on cohesiveness, affiliation and affection in interpersonal

relationships. Tauber (1972) indicated that shoppers are fond of affiliating with reference groups and

interacting with those who have similar interests. Westbrook and Black (1985) regarded affiliation as

a shopping value, and Reynolds and Beatty (1999) stress the importance of social motivations for

shopping. Wolfinbarger and Gilly (2001) propose that virtual community is a new platform of

sociality, meaning that Internet shopper can share updated information and related shopping

experiences with one another and compared with traditional social benefits from friends, virtual

community furnishes shoppers with fresh pleasure.

17

Alexander (1947) mentioned that the experimental psychologists have developed very

convincing evidence that women are more prone to social contacts than men, and reasonably

convincing evidence that they have more aptitude for maintaining such contacts. Based on the results

of carefully conducted aptitude and interest tests, the gender differences seem to be notable.

Dittmar et al. (2004) address that women, compared with men, have a strong desire for emotional

and social gratification in the Internet buying environment. Hence,

H25: Women have higher scores on sociality than men.

2.5 Attitude toward online shopping

Attitude towards a behavior refers to ―the degree to which a person has favorable or unfavorable

evaluation of the behavior of the question‖ (Grandom and Mykytyn, 2004). Attitude can be viewed

as the bridge between consumers’ background characteristics and the consumption that fulfills their

needs (Armstrong and Kotler, 2000; Shwu-Ing, 2003). A person’s shopping choices are influenced

by attitude (Haque et al., 2006).

Attitude toward online shopping can be defined as a person’s positive or negative feelings about

conducting the purchasing behavior on the internet (Chiu et al., 2005; Schlosser, 2003). The consumers’ attitude towards online shopping plays an important role in determining e-shopping

18

behaviors (Shwu-Ing, 2003). Because attitude is difficult to change; therefore, to understand consumers’ attitudes toward online shopping enables marketing managers to predict the online

shoppers’ behaviors and satisfy their needs (Armstrong and Kotler, 2000).

2.6 Gender as a Moderator

Numerous studies related to consumer behavior indicated that males and females differ in their

processing of information (Holbrook, 1986; Palmer and Bejou, 1995). In other words, males and

females differ in the response to alternative consuming stimuli (Meyers-Levy, 1989).The differences

between males and females suggest the potential moderating role of gender in the influence of

shopping values (convenience, availability of information, lack of sociality, adventure, and sociality)

on attitude toward Internet purchasing, because online shopping causes different stimuli than those of

physical store. Therefore, males and females would vary in making judgments when facing relevant

information online (Meyers-Levy and Sternthal, 1991), and this may result in gender differences in

attitudes toward Internet purchasing. The following hypotheses are rooted in this gendered analysis.

H26: The relationship between online shopping value and attitude toward online shopping is

moderated by gender.

19

2.7 Gender research

The discrepancy between men and women really does exist, including physical and mental differences. The differences drew marketing researchers’ interest that brought out related studies,

such as gender differences in decision-making styles (Vincent and Walsh, 2004), attitudes toward

Internet, catalog, and store shopping (Alreck and Settle, 2002), attitudes toward Internet and store

shopping (Dholakia and Uusitalo, 2002), online and store buying motivations (Dittmar et al., 2004),

perceived risk of buying online (Garbarino and Strahilevitz, 2004), and Internet shopping behavior

(Chang and Samuel, 2004). Moreover, Jackson et al. (2001) noted that though young women and

men use the Internet equally often, they use it differently, and this may influence the motivations of

buying online. This steam of research may be a fertile area in marketing.

2.8 Summary

This chapter developed a conceptual framework based on technology acceptance model. The

literature review provided necessary and sufficient statements to support the hypotheses which

specify the relationships between the constructs: convenience and attitude toward online shopping,

information availability and attitude toward online shopping, lack of sociality and attitude toward

online shopping, adventure and attitude toward online shopping, and sociality and attitude toward

online shopping. In addition, gender has main effect on convenience, information availability, lack of

sociality, adventure and sociality, and the relationship between online shopping value and attitude

20

toward online shopping is moderated by gender. The following chapter illustrates the methodology

which will be used to examine the model.

21

Chapter 3. Methodology

This chapter presents the methodology used to examine the conceptual model. The following

addresses (1) the instrument design, (2) sampling, and (3) pretest and pilot study used in this study.

The details are presented as follows.

3.1 Instrument Design

The scales in this study are derived from previous studies, and are modified according to the

special conditions of Internet shopping. The scales are presented in the Appendix A. The

questionnaire is composed of three parts, the first part included 15 items to measure the utilitarian

and hedonic values of Internet shopping. The second part included four items measuring the Internet shoppers’ attitude toward online shopping. The last part collected the demographic data of the

subject. Detailed definitions of the dimensions are provided in the following text.

Utilitarian values

The items of convenience are derived from the questionnaire of Eastlick and Feinberg (1999) and

Pui et al. (2007). Information availability was assessed using a 3-item version of the scale developed

by Wolfinbarger and Gilly (2001) and Pui et al. (2007), while the items of lack of sociality are

adopted from the scale developed by Pui et al., (2007). Respondents were scored on a scale ranging

from 1 = total disagreement to 7 = total agreement. The internal consistency of each shopping value

22

met the standard of Cronbach’s α in excess of .7 with sufficient reliability (Nunnally and Bernstein,

1994).

Hedonic Values

The items of adventure value were adopted from the questionnaire of Arnold and Reynolds (2003),

whereas the items of sociality value come from the scale developed by Arnold and Reynolds (2003)

and Pui et al. (2007). Item responses were on a 7-point Likert-type scale, ranging from 1 = total

disagreement to 7 = total agreement. The Cronbach’s alpha coefficient for each shopping value

exceeded .7, indicating that the scale had adequate reliability (Nunnally and Bernstein, 1994).

Attitude toward Online Shopping

Attitude refers to a consumer's overall evaluation of online shopping as a way of shopping, which

can be positive / favorable or negative / unfavorable. The items used to measure the attitude toward

online shopping were modified from the scale developed by Taylor and Todd (1995). Attitude

toward online shopping was measured by four items. Respondents respond to the items using a

seven-scale Likert-type scale. The alpha coefficient of this variable was 0.88 with sufficient reliability

(Nunnally and Bernstein, 1994).

23

3.2 Sampling

The data came from Taiwanese universities. Respondents were approached in and around a

university community located in a major metropolitan area during October of 2009. Sampling is

conducted via convenient sampling. Study subjects were undergraduate students in Taiwan who have

shopped online. Notably, university students play an important role in online shopping and represent

a long-term potential market (Bruin and Lawrence, 2000). A self-administered questionnaire was

randomly distributed to 600 students attending the chosen school. Of the 308 questionnaires returned,

12 were incomplete. The remaining 296 were valid for analysis, representing a response rate of

49.33%. Among the 296 subjects, 168 (56.7%) were males and 128 (43.3%) were females.

Note: N = 296.

3.3 Pretest and Pilot Study

Pretest was adopted before conducting formal survey, confirming that the questionnaire had no

semantic problem. Two Ph.D. candidates majoring in marketing serve as the subjects of the pretests.

The pretest was performed in an open-end format that the subjects could propose any questions about

the items. During the process, the subjects suggested that the phrasing of certain items could be

revised, which included utilitarian value, hedonic value, and attitude toward online shopping.

According to several suggestions from the pretest subjects, we slightly revised wording of the items.

25

After the pretest, we conducted pilot test by distributing 60 questionnaires to some undergraduate

students having online shopping experience. A total of 30 questionnaires were received for reliability

analysis. This study examined Cronbach’s alpha of all constructs, and we eliminated some items that

the Cronbach’s alpha are below 0.7. The alpha coefficients of remaining items were above 0.7.

Finally, nineteen items remained in the questionnaire were used for later analysis.

3.4 Summary

This chapter provided information for instrument design and data collection. The measurement

scales for the constructs were adopted from previous studies. The following chapter will illustrate

statistical technique, structural model, fit indices of model fit and the result of the hypotheses testing.

26

Chapter 4. Analysis and Results

This chapter presents the results from the data analysis by using LISREL 8.51computer software.

The reliability and validity of the constructs are presented, followed by the discussion of model fit.

Finally, the hypotheses and the model are tested and the results are elaborated.

4.1 Analytical strategy

This study used structural equation modeling (SEM) to explore the relationships among the

variables. SEM enables researchers to definitely test research hypotheses concerning the

relationships among research constructs. This study used LISREL 8.51 to assess the fit of the

measurement and structural models, and calculated the values of incremental fit index (IFI) (Bollen,

1989), comparative fit index (CFI) (Bentler, 1990), normed fit index (NFI) (Bentler and Bonett,

1980), and root mean square error of approximation (RMSEA) (Steiger, 1990). If the values of IFI,

CFI and NFI exceed the cut-off value of 0.9, and the value of RMSEA is below the cut-off values

0.08, then the model is said to be acceptable (Hu and Bentler, 1999). In addition to the fit indices,

this study uses the parameter estimates in the structural model to test the hypotheses.

4.2 Reliability of Measures

To assess the internal consistency of the constructs, the Cronbach alpha values were examined

and were shown on Table 4.1. The result of six constructs ranged from 0.86 to 0.91, meeting the

27

lower standard of 0.7. In addition, the composite reliability (CR) shows the internal consistency of

the indicators assessing a given factor and is calculated by the formula suggested by Fornell and

Larcker (1981). If the value is higher than 0.7, we can conclude that the indicator is acceptable for a

composite reliability (Fornell and Larcker, 1981). As seen in Table 4.1, the CR scores of all

constructs exceeded the acceptable levels.

Table 4.1. Reliability of Measurement Scales

Construct Cronbach’s

CR

Convenience 0.91 0.92

Information availability 0.89 0.90

Lack of sociality 0.88 0.90

Adventure 0.86 0.87

Sociality 0.86 0.88

Attitude toward online shopping 0.88 0.89

4.3 Validity of Measures

Before testing the hypotheses, this study first conducted average variances extracted (AVE) to

ensure that respondents can explicitly distinguish the variables in this study. The average variances

28

extracted (AVE) represents the amount of variance captured by the construct’s measures relative to

measurement error and the correlations among the latent variables. The analysis indicated that all

items had factor loadings higher than 0.7 (see Table 4.2). As seen in Table 4.2, all of the AVE values

were larger than 0.5, revealing good convergent and discriminant validity (Fornell and Larcker,

1981).

Overall, all the constructs show very good reliability and validity. Since we confirmed the

reliability and validity of constructs, we then test our hypotheses by estimating the full model. A

structural model was used to test the previously presented hypotheses. SEM results for testing the

30

model depicted in Figure 4.1 revealed that the fit statistics of model were within the recommended

range (chi-square value= 310.27, d.f.=120 (p < 0.001), RMSEA=0.076; CFI =0.93; IFI=0.93;

NFI=0.90). All of these fit indices are within the acceptable limit, suggesting that the overall

structural model provides a good fit with the data. Owing to an excellent fit between the structural

model and the data, this study then tested the hypotheses according to its parameter estimates.

Figure 4.1. Original model.

31

4.4 Hypothesis Test

Hypothesis 11-15 depicted that online shopping values are positively related to attitude toward

Internet shopping. As observed, Table 4.3 represents summaries of the hypothesis tests. The

structural links to attitude toward Internet shopping from convenience (H11), availability of

information (H12), lack of sociality (H13), adventure (H14), and sociality (H15) are completely

supported. Therefore, the model is supported as five online shopping values positively influence

attitude toward online shopping, indicating that hypothesis 11-15 were fully supported. In addition, this study divided the sample respectively by men and women, further investigating across men’s

and women’s groups for latent means testing and subgroup analysis.

4.5 Latent Means Difference

Based on the above measurement model, latent means testing is conducted (Byrne, 2001). Table

4.4 represents the results of latent means testing. Given that the women group functions as the reference group, the members’ factor means are hence fixed to zero to examine the latent means

difference between the two subgroups. As seen in Table 4.4, the significantly positive estimate of the

latent means difference across the subgroups for construct H21 and H23 indicates that the scores on

convenience, lack of sociality are significantly higher for men than for women. On the other hand,

the significantly negative estimate of the latent means difference across the subgroups for construct

H22, H24 and H25 indicates that the scores on availability of information, adventure and sociality

are significantly higher for women than for men.
