Outcome Measures
Primary Outcomes (3)
Depressive Symptoms as Measured by the Inventory of Depressive Symptomatology - Clinician Rated (IDS-CR)
Inventory of Depressive Symptomatology - Clinician Rated. Scale range: 0-84 (higher = greater depressive symptoms)
8-week primary endpoint
Feasibility and Tolerability Measured by Percent of the Yoga Group Who Complete a Week 8 Assessment
Measured by percent of the yoga group who complete a week 8 assessment
8-week primary end point
Acceptability as Measured by the Acceptability Interview Completed at 8-week Endpoint or Early Termination
Acceptability Interview: A 19-question qualitative interview assesses perception of ease of participation, program likeability, and perceived benefits of the yoga program. Adapted from DeBoer et al. It was a 1-10 likert scale with 1 = lowest, 10 = highest to rate acceptability of the yoga intervention. These are the items we used: 1) how much did you enjoy the yoga itself?; 2) how much did you enjoy the aftereffects of the yoga?; and 3) how reasonable did you find the time commitment to be?
at the end of 8-weeks or early termination.
