    Cultural Adaptation and Statistical Validation of the General Self-Efficacy Scale Tamil (GSES-T)
    (School of Psychology. Faculty of Humanities and Sciences, SLIIT, 2025-10-10) Vasudevan, T; Selvaratnam, N. D
    The General Self-Efficacy Scale (GSES), extensively validated across cultures, has not previously been available in Tamil, restricting its application in research and practice. This study, guided by Classical Test Theory (CTT), aimed to translate, culturally adapt, and validate the GSES for Tamil-speaking populations. Adaptation followed rigorous procedures: forward–back translation, expert evaluation via the Delphi method (n = 4), and a pilot test (n = 10) to ensure cultural and linguistic relevance. Data from 204 Tamilspeaking Sri Lankans, recruited through cluster-based random sampling across multiple provinces, were analysed. Findings demonstrated strong content and consensual validity, excellent internal consistency (Cronbach’s α = .892), and a unidimensional structure explaining 50.98% of variance. The validated GSEST offers a robust tool for assessing self-efficacy, advancing culturally responsive research and supporting evidence-based interventions in Tamil-speaking communities
