Sample Size
SECONDARY
This study is a prespecified secondary analysis using data from a randomized clinical trial conducted from November 1, 2011, to April 1, 2014. A total of 248 clinicians were enrolled from 47 clinics. The sample size for this analysis was determined by the number of nonmissing job satisfaction scores from the original enrolled sample, which was 201 clinicians from 43 clinics. Assuming no interaction between interventions, an 80% response rate, at least 90% clinic participation, and an intraclinic correlation of 0.07, we have 80% power to reject the hypothesis that the intervention reduces job satisfaction on average by at least one-third of a Likert point.
