Psychological flexibility has been found as a protective factor for several psychological problems, including the field of parenting. The present study aims to illustrate a clinical protocol, session by session, for the promotion of parental psychological flexibility and emotion regulation in a case study. The clinical protocol is based on third-wave behavior therapy in a brief intervention of four sessions. The intervention is presented in a clinical case of a mother with a child diagnosed with Oppositional Defiant Disorder. Both mother and child experienced problems with emotional regulation and psychological flexibility. The results show clinically significant improvements in psychological flexibility, emotional regulation, and stress parenting in the mother both after the intervention and at follow-up. In the child, emotional perspective-taking skills, acceptance, and valued actions improved. The case illustrates in detail the application of different strategies of acceptance, mindfulness, emotion regulation, and emotional defusion applicable to parenting. Clinical implications are discussed.
