Development of the Seasonal Beliefs Questionnaire: A Measure of Cognitions Specific to Seasonal Affective Disorder
Abstract
Rohan's (2002) integrative, cognitive-behavioral model proposes that individuals with seasonal affective disorder (SAD) experience frequent thoughts related to light availability and the seasons. To date, no measure exists to determine the existence and extent of these hypothesized SAD-specific cognitions. This study developed a preliminary 94-item self-report measure, the Seasonal Beliefs Questionnaire (SBQ), which was administered with several depression, seasonality, and cognitive measures via a secure web site to 104 college students from two universities. Volunteers returned approximately 2 weeks later and completed the SBQ again. The SBQ demonstrated high internal consistency (Cronbach's alpha = .98), high test-retest reliability (r = .93), good convergent validity with other cognitive measures for SAD (rs = .57-.84), and good divergent validity (r = .27). Based on these promising preliminary psychometrics, continued validation of the SBQ is warranted. Future studies with larger samples will reduce the number of items and perform a confirmatory factor analysis.
