Methodological changes to improve retention: Results from two pediatric cognitive behavioral therapy studies

Abstract

AbstractObjectiveRetention is challenging in clinical research with pediatric populations. The retention obstacles that are experienced in adult samples are compounded because child samples depend on caregiver support and engagement. The present paper describes retention improvements following protocol adaptations across a pair of cognitive behavioral pilot studies for nightmare sufferers aged 6–17.MethodsStudy 1 (N = 20) focused retention efforts on rapport and engagement, flexible scheduling, treatment location choice, and incentives. Study 2 (N = 31) sought to increase retention by improving continuity of care, increasing scheduling flexibility, reducing participant time and effort, and increasing choice and attractiveness of incentives.ResultsOnly 13 participants (65%) were retained in Study 1; n = 6 (54.5%) treatment and n = 7 (77.78%) waitlist. In contrast, 29 participants (93.5%) were retained in Study 2; n = 15 (93.8%) treatment and n = 14 (93.3%) waitlist.ConclusionWe conclude that asking for and responding to patient feedback to assess all perceived barriers and burdens for participants is essential to ensure that benefits exceed effort. Allowing choices in size and frequency of incentives, as well as improving continuity of care, and reducing session length even while increasing number of sessions, were noted improvements in Study 2.
