73 within the social advertisement. Examples of strategies are informational, humoral, and emotional (Lawrence et al., 2013). Next, an important part of user-generated social advertising that this research did not focus on is the perceived level of trust. It is said that consumer-generated advertisements are trusted more than brand-consumer-generated, but does this influence the internal psychological process and decision-making of the consumer? On a broader note, it is encouraged that researchers expand the knowledge about social commerce further and test other social commerce constructs in this setting, such as personalization and the conversations between the brand and the consumer. Lastly, it is also recommended to test this model across different social media platforms, such as Facebook, Pinterest, YouTube, TikTok, and Twitter, which are not fair behind Instagram with exploring social commerce options (Gomez, 2021).

74 advertising: brand-generated versus user-generated) x 2 (advertised product: hedonic versus utilitarian) experiment, both with a between-subjects design. Based on these experiments, it can be concluded that social advertising does influence the internal psychological process of the consumer, such that brand-generated social advertising leads to a stronger cognitive appraisal and user-generated social advertising leads to a stronger affective appraisal. However, the experiments also showed that there exists no direct relationship between social advertising and the decision-making (i.e., purchase intention) of the consumer; this is always mediated by the internal psychological process (i.e., cognitive and affective appraisal). Furthermore, the results indicate that the moderated effect is only significant for the effect of user-generated social advertising on cognitive appraisal. Finally, both the hedonic and utilitarian advertised products demonstrated a significant positive influence; however, the effect of the utilitarian product was even stronger.

The results provide important theoretical contributions for researchers. First of all, this research extends the knowledge about social commerce by confirming an additional social commerce construct: social advertising. As a result, the application scope of the social learning theory is extended, as well as the understanding of the consumer’s purchase decision-making process within the social advertising context. Moreover, it expands the knowledge about social advertising, specifically for Instagram. Lastly, this study proved that the type of advertised product influences the internal psychological process of the consumer. Next, based on these conclusions, this research provides important implications for practitioners. Firstly, managers should consider allocating part of their marketing budget towards social advertising to expand the social commerce activities of their company. In order to increase the purchase intention of consumers, it is important to enhance the cognitive or affective appraisal of social advertisements based on their specific goals and what they want to communicate in their advertisements. Moreover, this study proved how important it is to incorporate user-generated

75 social advertising in the marketing strategy. Lastly, this study encourages policymakers to help consumers in identifying commercial content.

This research does not come without its limitations. However, this simultaneously establishes new areas for future research. The most important limitation is that neither experiment included a pretest for the used products and social advertisements. Next, the used products in the social advertisements fall into the same categories: fashion and business-to-consumer. Future research can use different product categories such as business-to-business.

Additionally, future research could research the reason why user-generated advertising with a utilitarian product led to a higher affective appraisal, which was the opposite of hypothesis 6.

Future research can also use different moderators, such as videos versus photos. Next, other interesting areas for future research are to investigate the interplay of brand-generated and user-generated social advertising, the influence of cultural differences on the purchase decision-making process of the consumer, the different strategies that are used in social advertising, and the influence of perceived levels of trust on the internal psychological process and decision-making of the consumer. Most importantly, it is encouraged that researchers expand the existing research by testing other social commerce constructs inside and outside the current setting and by testing different social media platforms.

To conclude, this research filled an important gap in the literature by expanding the available knowledge about online consumer behavior, specifically in social commerce.

Additionally, it introduced an additional social commerce construct by identifying the importance of the role that social advertising plays in the internal psychological process of the consumer. Lastly, this research has demonstrated the potential of social commerce and social advertising. In turn, this hopefully encourages researchers and practitioners to expand this knowledge even further.

88 Appendix B – Operationalization of the variables

The operationalization of the variables cognitive appraisal, affective appraisal and purchase intention is explained below.

Appendix B1 – Mediator cognitive appraisal

Cognitive appraisal will be measured using four statements (Martín-Consuegra et al., 2019) with a seven-point Likert scale (1 = strongly disagree, 7 = strongly agree). A seven-point Likert scale is shown to be more sensitive, accurate, easier to use, and provides a better reflection of a respondent’s true evaluation (Finstad, 2010). Martín-Consuegra et al. (2019) examined consumer luxury brand-related behavior intentions in a social media context and the moderating role of hedonic and utilitarian motivations. The hedonic and utilitarian motivations are the same as cognitive and affective appraisal. The statements are as follows:

1. The social advertisements are helpful for me.

2. The social advertisements are functional for me.

3. The social advertisements are useful for me.

4. The social advertisements are practical for me.

Appendix B2 – Mediator affective appraisal

Affective appraisal will be measured using four statements (Martín-Consuegra et al., 2019) with a seven-point Likert scale (1 = strongly disagree, 7 = strongly agree). The statements are:

1. I perceive the social advertisements as fun.

2. I perceive the social advertisements as exciting.

3. I perceive the social advertisements as pleasant.

4. I perceive the social advertisements as entertaining.

89 Appendix B3 – Dependent variable purchase intention

Lastly, the purchase intention of the respondents will be measured using four statements (Duffett, 2015) with a seven-point Likert scale (1 = strongly disagree, 7 = strongly agree).

Duffett (2015) researched the influence of Facebook advertisements on intention-to-purchase and purchase amongst millennials. Since Facebook advertisements can be compared with Instagram advertisements, the four statements Duffett (2015) used in his study are well suited to measure the purchase intention in this study.

1. I will buy the sunglasses that were advertised in the social advertisements.

2. I desire to buy the sunglasses that were promoted in the social advertisements.

3. I am likely to buy the sunglasses that were promoted in the social advertisements.

4. I plan to purchase the sunglasses that were promoted in the social advertisements.
