## 2 Literature Review and Hypothetical Relationships in the Research Model
### Techno-Psychological Acceptance Theoretical Model  
The theoretical model of this study is an innovative, integrated framework comprising two components: technology acceptance and psychological acceptance. The aim is to explore consumer behavior intentions. The technology acceptance part is primarily based on the Unified Theory of Acceptance and Use of Technology (UTAUT), which includes the constructs of Performance Expectancy (PE), Effort Expectancy (EE), Social Influence (SI), Facilitating Conditions (FCs), and behavioral intention (BI). It has emerged as a pertinent and efficacious analytical framework [35; 36]. Originally devised to assess the extent of technology adoption, the UTAUT framework stands preeminent in explicating users' behavioral intentions within this domain, consequently assuming the mantle of seminal reference theory. The UTAUT primarily focuses on organizational contexts, whereas the UTAUT2 extends the model to include consumer use contexts and introduces three additional constructs to better capture consumer behavior, namely, Hedonic Motivation, Price Value, and Habit [36], underpinned by a focus on consumer technology acceptance. By incorporating the new constructs and extending the application context, the UTAUT2 enhancesthe explanatory power of the model, providing a more comprehensive understanding of the factors influencing technology acceptance and use, thus making it more applicable to a broader range of technology adoption scenarios. This accommodation is made to harmonize the research's actual exigencies, objectives, environmental considerations, and overarching scholarly backdrop. In addition, the psychological acceptance part is dominantly underpinned by the dual constructs of affirmative psychological contentment and adversative psychological perceived risk. The significance of the influence of satisfaction on consumers' behavioral intentions is of paramount importance, but the UTAUT framework, due to its inherent structure, does not overtly encapsulate the satisfaction quotient germane to the gamut of technological acceptance, thus delineating a limitation that has precluded its broader adoption within scholarly discourse [37]. Satisfaction is an elemental construct [38] characterized by a multidimensional framework [39], manifesting through an array of formative indicators that delineate disparate facets [40]. Therefore, the influence of satisfaction on technology acceptance remains intricate and multifarious. In accordance with [PERSON]'s study suggestions, satisfaction, as a core concept, should be measured by combining multiple dimensions in a complementary manner [40]. Therefore, this study references the necessity in the UTAUT2 of measuring consumers' Hedonic Motivation (the enjoyment or pleasure derived from using technology), Price Value (the perceived cost-benefit trade-off), and Habit (the extent to which behaviors are performed automatically due to learning) for the psychological perception of technology. Satisfaction is measured from three perceived dimensions, namely, Perceived Emotional Value (PEV), Perceived Price Value (PPV), and Perceived Functional Value (PFV), collectively termed perceived value. The sub-dimensions exert an impact on the central construct of satisfaction in independent, complementary, and non-interfering manners [41]. Therefore, they are grouped in perceived value as sufficient and necessary factors collectively serving as the analytical conduits through which satisfaction is measured and evaluated. Perceived risk has been empirically substantiated across diverse domains as a pivotal determinant, exerting adverse effects on behavioral intentions and satisfaction, among other crucial dimensions [42]. In addition, perceived risk also serves to achieve reverse measurement and validation. Furthermore, it has been incorporated as an exogenous validating factor within the framework of the UTAUT [43]. It is also worth mentioning the mediation and cross-comparison in the UTAUT.
