The Service User Technology Acceptability Questionnaire: Psychometric Evaluation of the Norwegian Version

BACKGROUND: When developing a mobile health app, users’ perception of the technology should preferably be evaluated. However, few standardized and validated questionnaires measuring acceptability are available. OBJECTIVE: The aim of this study was to assess the validity of the Norwegian version of the Service User Technology Acceptability Questionnaire (SUTAQ). METHODS: Persons with type 2 diabetes randomized to the intervention groups of the RENEWING HEALTH study used a diabetes diary app. At the one-year follow-up, participants in the intervention groups (n=75) completed the self-reported instrument SUTAQ to measure the acceptability of the equipment. We conducted confirmatory factor analysis for evaluating the fit of the original five-factor structure of the SUTAQ. RESULTS: We confirmed only 2 of the original 5 factors of the SUTAQ, perceived benefit and care personnel concerns. CONCLUSIONS: The original five-factor structure of the SUTAQ was not confirmed in the Norwegian study, indicating that more research is needed to tailor the questionnaire to better reflect the Norwegian setting. However, a small sample size prevented us from drawing firm conclusions about the translated questionnaire.
