Table 1 Summary of studies based on TRA and ECT.

(Lau et al., 2023)

To explore the attitudes of young consumers towards purchasing luxury fashion using partial least squares structural equation modeling (PLS-SEM).

Data source:

Survey (237 young consumers of luxury fashion in Hong Kong)

Method: PLS-SEM

TRA, Social identity theory, and the Affect-behavior-cognition (ABC) model.

Affect- and cognition-based attitudes were identified as antecedents that bolstered brand appeal, consequently exerting a positive impact on purchase intentions.

(Rausch and Kopplin, 2021)

This study seeks to identify the primary determinants of sustainable clothing purchase behavior and to illuminate the gap between purchase intentions and actual purchasing behavior of sustainable clothing.

Data source:

Survey (464 available data)

Method: PLS-SEM

TRA and Theory of planned behavior (TPB)

The attitude towards sustainable clothing exerts the most significant influence on purchase intention. However, this relationship is adversely affected by consumers’ concerns about greenwashing. Additionally, consumers’ perceived aesthetic risk harms the intention-behavior relationship, while perceived economic risk does not significantly affect this relationship.

(Nguyen et al., 2020)

Investigating the various factors influencing consumer attitudes and intentions towards purchasing functional foods in an emerging market economy.

Data source:

Survey (596 available data from Vietnamese)

Method: SEM

TRA

Health consciousness and subjective norms play a significant role in strengthening consumers’ attitudes toward buying functional yogurts, with the perceived price of functional yogurts negatively affecting these attitudes. Additionally, subjective norms and attitudes are important predictors of consumers’ intentions to purchase functional yogurt.

(Chatterjee et al., 2022)

Exploring the influence of online customer reviews and electronic word-of-mouth (eWOM) on customers’ intent to purchase.

Data source:

Survey (There are a total of 585 valid responses, with 305 from India and 280 from the United Kingdom.)

Method: PLS-SEM

Socialization theory, TRA,

Congruity theory and Expectation value theory (EVT)

In both the United Kingdom and India, eWOM and online customer reviews play a pivotal role in shaping purchase intentions. Notably, gender has no discernible impact on purchase intentions for UK consumers, while age and gender significantly influence the purchasing decisions of consumers in India.

(Wu et al., 2020)

Investigating the factors influencing the formation of impulsive consumer behavior.

Data source:

Survey (352 available data)

Method: PLS-SEM

ECM and the Flow theory

The perceived risk of virtual stores, the design of online stores and the psychological state of online shopping are closely related to online impulse shopping.

(Tata et al., 2021)

Investigate how the characteristics and confirmation from six e-retailers impact shoppers’ satisfaction or regret and further explore the influence of these cognitive constructs on post-purchase behavior.

Data source:

Survey (367 available data)

Method: SEM

ECM and the Regret theory

The influence of product features on satisfaction, in comparison to factors like price and service, is not consistently significant. Furthermore, satisfaction and regret commonly demonstrate contrasting effects in the majority of post-purchase behaviors.

(Du et al., 2022)

The study explores the influence of information system quality characteristics and brand-related factors on consumers’ intention to repurchase knowledge services.

Data source:

Survey (301 available data from

China)

Method: PLS-SEM

Information systems success model, Social identity theory, and ECT

The success factors of the information system positively influence user satisfaction, and both user satisfaction and switching barriers contribute positively to the repurchase intention for online knowledge services.

(Istijanto et al., 2023)

Investigate the impact of new product attribute features on user satisfaction and purchase intention (taking Cookies enriched with spirulina as an example).

Data source:

Survey (316 available data from Jakarta, the capital city of Indonesia)

Method: SEM

Stimulus-Organism-Response (S-O-R) theory and ECT

The data results indicate that the thickness and texture of the new product did not significantly affect consumer satisfaction. However, all other features were confirmed by the data. Furthermore, an increase in consumer satisfaction with the product is associated with a corresponding rise in their purchase intentions.

(Shiau et al., 2020)

Investigate users’ intentions for continued use of financial technology from the perspectives of their self-efficacy and experience.

Data source:

Survey (753 available data)

Method: PLS-SEM

Expectation confirmation theory of IS continuance and the theory of Self-efficacy

The utilization of self-efficacy and the ECT-IS theory provides a robust explanation for fintech continuance intentions. Furthermore, confirmation acts as a mediator variable between self-efficacy and perceived usefulness.
