Analyzing the Impact of Questionnaire Length on Respondent Burden Through Biosensors

Self-report questionnaires are fundamental tools of psychological research. However, the cognitive effort required for questionnaire completion, known as response burden, poses challenges to data quality and participant engagement. While questionnaire length is often addressed as a key element of response burden, empirical evidence on its impact remains unclear. This study introduces a novel methodological approach employing biosensors to investigate respondent burden. In particular, Galvanic Skin Response (GSR) was measured. Participants completed two personality tests of differing lengths while their physiological signals were recorded. Preliminary findings from five participants will be presented. Despite limitations in sample size, this study contributes to the evolving landscape of psychometric questionnaires methodology by offering a nuanced perspective on respondent burden to enhance questionnaire design and data collection practices.
