Abstract

Objectives: The purpose of this study was to develop and validate the Thai version of the Interpersonal Confidence Questionnaire (ICQ) to assess interpersonal confidence among Thai university students.


 


Materials and methods: This study employed quantitative research design. The study population was 13,616 undergraduate-students between 18-23 years old studying at Kasetsart University, Sriracha Campus. The authors use a cluster random sampling method and there were 528 respondents. The ICQ was constructed by Novák in 2017, consists of 30 items and comprised of positive and negative items. This develops Thai version of ICQ led to a review of the literature and a number of relevant items were identified to incorporate. To begin with, Bandura’s self-efficacy theory (1977, 1982) is about a person’s beliefs in their abilities and the impact on decisions and efforts in social settings. Next, Leary and Kowalski’s Social anxiety theory (1995) describes how fear of negative evaluation leads to avoiding social contact. In addition, social competence and assertiveness (Anderson-Butcher et al., 2016) emphasize the value of social skills and the ability to work with others. Informed by these frameworks, the ICQ-Thai was reconstructed into three dimensions, still comprising positive and negative items. The methodological approach was structural equation model (SEM) with confirmatory factor analysis (CFA) was used to evaluate structural validity and reliability.


 


Results: The model demonstrated good fit with the empirical data (χ²/df = 1.666, RMSEA = 0.045, CFI= 0.989). The construct reliability (ρc = 0.878) and average variance extracted (ρv = 0.554) confirmed acceptable convergent validity and internal consistency.


 


Conclusion: The Thai version of the Interpersonal Confidence Questionnaire (ICQ) was feasible to evaluate interpersonal confidence among Thai university students.
