Abstract: Purpose: To establish test-retest reliability and clinical utility of the Students Life Satisfaction Scale (SLSS), the Brief Multidimensional Students Life Satisfaction Scale (BMSLSS), and the Self-determination Scale (SDS), in youth aged 12-17 who have a stable non-progressive physical disability. Method: Study Design: Repeated measures with 5-10 day testing interval. Procedure: Youth were identified by clinicians at Bloorview Kids Rehab and contacted by student investigators. Participants completed questionnaires via SurveyMonkey. Statistical analysis (SPSS 16.0) was performed to determine standard error of measurement, minimal detectable change (MDC), mean, standard deviation, Inter-class Correlation Coefficient (ICC) type 2:1, and associated 95% confidence interval (CI). Results: Thirteen participants completed both baseline and follow-up questionnaires. ICCs for the total score of each questionnaire were all above 0.85 with wide variance in 95% CIs. The MDCs for the SLSS, BMSLSS, and SDS are 3.92, 3.68, and 2.76, respectively. Conclusion: The excellent test-retest reliability suggests these measures will be useful tools for tracking change in life satisfaction in youth with stable non-progressive physical disabilities. Youth generally enjoyed completing the questionnaires. Limitations include participant demographics and the small sample size; potentially attributable to method of recruitment, process of consent, or mode of completion, highlighting directions for future research.
