Despite many studies on the characteristics associated with resilience, there is little research on interventions to promote resilience in adults. The aims of this study were to gather preliminary information regarding the feasibility of implementing a group psychosocial resilience training program (REsilience and Activity for every DaY, READY) in a workplace setting, and to assess if program would potentially promote well-being. The program targets five protective factors identified from empirical evidence: Positive emotions, cognitive flexibility, social support, life meaning, and active coping. Resilience enhancement strategies reflect core acceptance and commitment therapy (ACT) processes and cognitive behavior therapy strategies. Sessions involve psychoeducation, discussions, experiential exercises, and home assignments. Sixteen participants completed 11two h group sessions over 13 weeks. Baseline and post-intervention assessment included self-administered questionnaires, pedometer step counts, and physical and hematological measures. Data were analyzed using standardized mean differences and paired t-tests. There was a significant improvement between baseline and post intervention scores on measures of mastery (p=0.001), positive emotions (p=0.002), personal growth (p=0.004), mindfulness (p=0.004), acceptance (p=0.012), stress (p=0.013), self acceptance (p=0.016), valued living (p=0.022), autonomy (p=0.032) and total cholesterol (p=0.025). Participants rated the program and materials very highly. These results indicate that the READY program is feasible to implement as a group training program in a workplace setting to promote psychosocial well-being.
