ABSTRACT

Purpose The rapid advancement of information and communication technology (ICT) necessitates a comprehensive examination of the determinants influencing its adoption. This study integrates Self-Determination Theory (SDT), the Theory of Planned Behaviour (TPB), and the Task-Technology Fit (TTF) framework to explore the psychological and social variables that shape user engagement with ICT. The primary objective was to assess how autonomy, competence, relatedness, subjective norms, perceived behavioural control, and the alignment between technology and task collectively affect individuals’ behavioural intentions and actual adoption of ICT. Methodology The research employed a quantitative methodology, analysing structured survey data collected from 430 respondents. Using SmartPLS 4, structural equation modelling (SEM) was conducted to investigate the interrelationships among the study variables. Results The findings confirm that perceived autonomy, competence, and relatedness significantly enhance autonomous motivation, which in turn influences perceived behavioural control and attitudes, while also shaping subjective norms in accordance with the TPB framework. ICT adoption is shown to be strongly influenced by subjective norms, although alignment between user requirements and technological capabilities (TTF) facilitates adoption. Conversely, a poor fit between task demands and technological features presents a substantial barrier to adoption. Implications for Research and Practice. This study contributes meaningfully to the literature by presenting an integrative model that synthesises psychological theory, behavioural intention constructs, and technological fit dimensions to explain ICT adoption. The implications are practical and far-reaching, offering strategies for organisations to develop ICT utilisation skills, and providing policy makers and educators with actionable recommendations to enhance implementation and promote effective task-technology integration.
