title: Boosters, anyone? Exploring the added value of booster sessions in a self-management intervention.
abstract: The current study explored the benefits of adding booster sessions to a validated and successful self-management intervention for type 2 diabetes patients (i.e. Beyond Good Intentions). Although the addition of booster sessions to self-management interventions is often recommended, it has not been empirically established to what extent booster sessions are in fact appreciated by participants. Participants in the current study (N = 129) followed the Beyond Good Intentions program and were offered a series of three booster sessions at 1, 3 and 5 months afterwards. Primary outcome variables included participants' attendance and evaluations of the booster phase. In addition, self-management behavior was assessed at baseline (T1), after the initial phase (T2) and after the booster phase (T3). Results showed that more than one-fourth of participants who completed the initial phase dropped out during the booster phase, and those who did complete both phases evaluated the booster phase significantly less positive as compared to the initial phase. With regard to the behavioral outcomes, we replicated previous findings showing positive effects on all measures during the initial phase. The booster phase, however, did not result in further improvements. It was concluded that the added value of booster sessions was, at best, questionable.
