Development and Validation of a Basic Psychological Needs Scale for Technology Use

摘要

The aim of this work was to develop a valid and reliable scale to measure Basic Psychological Need Satisfaction for technology use (BPN-TU). According to the Self-Determination Theory, satisfaction of the Basic Psychological Needs (BPNs) for Autonomy, Competence, and Relatedness is crucial to well-being and autonomous motivation. Research into the role of BPN Satisfaction in technology use is scarce, partly due to a lack of appropriate measuring tools. To develop a pool of original BPN-TU scale items, we held 10 interviews. Based on these items, we conducted four validation studies with four independent samples (total N = 821), collecting user responses to different technologies: digital voice assistant, exoskeleton, chatbot and social robot. Good model fit was supported by confirmatory factor analyses for a twelve-item scale, containing three items each for satisfaction of users' Autonomy, Competence, Relatedness to Others, and Relatedness to Technology. The scale was validated in English and German.
