Positive Events Training (PET)
BehavioralPET is a group-based training program combining Memory Specificity Training (MEST; Raes, 2007) and Future Event Specificity Training (FEST; Dutch version of Hallford et al. (2020): Changing the Future: An initial test of Future Specificity Training). It comprises four sessions of 50 minutes each. The training is delivered in a standardized manner, using the Positive Event Training Manual developed for this study (content adapted from our MEST and FEST manuals). Following brief psychoeducation on the rationale, participants practice generating detailed specific memories and future events using neutral and positive cue-words. Participants are maximally supported and challenged by the trainer and by the other group-members to generate very specific and highly detailed memories and future events using mental imagery and drawing upon visual, olfactory, auditory and emotional elements of the events, including both contextual and sensory-perceptual details.
