Health Coaching: A Pilot Trial Among Reintegrating Veterans

This pilot study is designed to provide data to inform the design and procedures of a future efficacy trial of health coaching among reintegrating Veterans. An enrollment rate 30% and an assessment completion rate 65% at 9 months will be considered feasible enrollment and assessment completion rates for a future efficacy trial. An intervention completion rate 70% and mean score 27 on the Client Satisfaction Questionnaire-8 will indicate acceptability. Evaluation of measures will entail quantifying the mean levels in this population, characterizing typical variation in the outcomes, descriptive analyses of within-person change across time, and adjusted estimates of treatment effect sizes with 95% confidence intervals to calibrate the sample size needs of a fully powered trial. Qualitative interviews with participants will provide information on barriers and facilitators to implementation as well as perceived benefits and potential harms.
