Validation of the German basic psychological need satisfaction in sleep scale

Area of Science:

• Psychology
• Sleep Science
• Health Psychology

Background:

• Basic psychological need theory links need satisfaction (autonomy, competence, relatedness) to well-being and health, including sleep.
• Previous research explored the link between need satisfaction and sleep quality, but lacked a sleep-specific measurement tool.
• A validated questionnaire for assessing basic psychological need satisfaction specifically within the sleep domain was absent.

Purpose of the Study:

• To construct and validate the Basic Psychological Need Satisfaction in Sleep Scale (BPNSS-S).
• To provide a reliable and valid instrument for assessing need satisfaction related to sleep.
• To facilitate research on improving sleep quality and well-being through need satisfaction.

Main Methods:

• Study 1: Confirmatory factor analysis and item selection to develop the initial BPNSS-S using 227 participants.
• Study 2: Validation of the final 7-item BPNSS-S with 295 participants, alongside measures of sleep quality, life satisfaction, and exercise-related need satisfaction.
• Statistical analyses included confirmatory factor analysis and validity assessments (criterion, construct, discriminant).

Main Results:

• The final 7-item BPNSS-S demonstrated good to excellent model fit.
• The scale showed strong criterion, construct, and discriminant validity, aligning with other established measures.
• The BPNSS-S proved to be a reliable and valid tool for assessing psychological need satisfaction in the sleep domain.

Conclusions:

• The developed BPNSS-S is a psychometrically sound instrument for sleep research.
• This scale enables a deeper understanding of how need satisfaction influences sleep quality and overall well-being.
• The BPNSS-S can guide interventions aimed at enhancing sleep behavior and promoting well-being across diverse populations.
