BACKGROUND: Research on test-retest reliability of the Season Pattern Assessment Questionnaire (SPAQ) is sparse, and to date, has not been done with subgroups such as the Old Order Amish. METHODS: We examined the test-retest reliability of the SPAQ in a sample of Old Order Amish. A total of 68 Old Order Amish participants completed the SPAQ twice, with 4 months between administrations. Quantitative data analyses were carried out to determine respective strengths of test-restest reliability for two variables [i.e., Global Seasonality Score (GSS), and Problem Rating Score (PRS)]. RESULTS AND CONCLUSIONS: Results revealed the test-retest reliability of the SPAQ in this population to be strong within the respective variables (GSS, α= 0.87; and PRS, α= 0.79) using Cronbach's alpha.
