Imagery rescripting (ImR) has shown to reduce negative belief about the self, negative emotions and emotional dysregulation. However, the mechanisms through which this improvement in emotion regulation takes place is currently the object of investigation. An untested hypothesis is that ImR reduces the negative emotional response to primary emotions (i.e. the Meta-emotional problem) associated to difficulties in emotional regulation. In this study, the researchers aimed to investigate the impact of group ImR delivered via telehealth on dysfunctional personality beliefs, the Meta-emotional problem, difficulties in emotional regulation, and self-compassion in a non-clinical sample of participants. A total of 45 community sample participants received three sessions of group ImR delivered via telehealth. Personality dysfunctional beliefs, meta-emotions, self-compassion and emotional dysregulation were measured before ImR and in three follow-up sessions. Dysfunctional personality beliefs, specifically those associated with the dependent, obsessive–compulsive, antisocial, and histrionic personality disorders, were significantly reduced after the ImR intervention. Additionally, the Meta-emotional problem and difficulties in emotional regulation were also reduced. Moreover, negative self-compassion showed a significant decrease after ImR, but positive self-compassion remained unchanged. These findings suggest that group ImR delivered via telehealth can effectively reduce negative beliefs about oneself, negative emotions, and emotional dysregulation. However, it seems that this intervention does not increase a more benevolent attitude towards oneself, possibly due to the less direct intervention of the therapist in the group telehealth setting. The researchers discuss the implications of these findings for clinical practice in a group telehealth context.
