Abstract
Background: Bedtime procrastination (BP) is an increasingly prevalent behavior with detrimental outcomes for
individuals. Three reasons for BP have been identified: Deliberate procrastination, mindless procrastination, and
strategic delay. Developing an instrument to assess the reasons for BP allows better identification of patterns of
behaviors and tailored interventions. The present study aims to develop and study the psychometric properties of the
Reasons for Bedtime Procrastination Scale (RBPS). Method: The study sample included adults living in Portugal (N =
653). Validity and reliability analyses were conducted. Results: Principal component analysis suggested that the RBPS
is composed of two factors (factor 1 – deliberate and mindless reasons; factor 2 – strategic reasons). Confirmatory
factor analysis supported the two-factor structure of the scale (e.g., CFI = .984; TLI = .976 RMSEA = .053). The
scale demonstrated good internal consistency, with a Cronbach’s alpha coefficient of .85 for factor 1, and of .72 for
factor 2. Convergent validity was supported by significant correlations with the number of activities people engage in
before going to bed, BP, bedtime gap, fall-asleep time gap, and wake-up time gap. Conclusions: The RBPS appears to
represent a reliable way of assessing reasons for BP in the general adult population.
