Abstract

Product-moment correlation is often used to verify the internal structure of a construct. Despite its widespread use among undergraduate and graduate students, and its inclusion in nationally distributed textbooks, the author argues that this technique is fundamentally flawed. This study aims to explain the shortcomings of product-moment correlation. This study found that Confirmatory factor analysis (CFA) is the appropriate technic for that purpose because use only common variance, latent variable score is obtained only from its verified indicators and the researcher can check the ability of each indicator ability to explain its latent variable.

Generation Z is known for being critical and highly sensitive to prices, promotions, and technology. It is interesting to investigate how they use an application continuously. The authors postulate that the application's user interface quality is the key. Therefore, this research aims to investigate the influence of user interface quality on use continuation intention among Generation Z. To answer this research problem, the authors collected data using online questionnaires via Google Forms from 170 respondents selected through judgmental sampling. Data are analyzed using Structural Equation Modelling (SEM) with the help of WarpPLS 8.0. This study reveals that simplicity, directionality, informativeness, user-friendliness, comprehensiveness, personalization, and internal factors have a positive and significant effect on use continuation intention, while connectivity, interactivity, and continuity have no effect.

Abstract

The research started with a premise that individuals could take the initiative and regulate their behavior to generate Significant Others’ Anticipated Emotions (SOAEs). Could the SOAEs function as a social element of behavior in addition to subjective norms (SN)? The research aimed to answer this question. Therefore, the researcher extended the Theory of  Planned Behavior (TPB) and argued that the SOAEs influenced behavioral intention through attitude toward behavior based on cognitive balance theory. In the smoking abstinence behavioral context, the researcher tested the extended model. The data from 242 respondents chosen conveniently, analyzed using structural equation modeling, revealed that Significant Others’ Anticipated Joyfulness (SOAJ) for smoking abstinence behavior and Significant Others’ Anticipated Distress (SOAD) for smoking behavior positively influences anti-smoking behavior through attitude. Moreover, the sole influence of the SOAJ and cumulative influence of SOAJ and SOAD on smoking abstinence intention are higher than that of the SN. As a new component of TPB, the SOAEs complement and do not rival the SN. Other researchers can utilize a longitudinal research design and test the extended model in different contexts of behaviors.
