Mentalization-Based Therapy for Mothers with Childhood Maltreatment History: A Randomized Controlled Trial
摘要
Mothers with a history of childhood maltreatment often face parenting challenges, including difficulties in emotion regulation, heightened risk of parental burnout, and impairments in reflective functioning. This randomized controlled trial evaluated the effectiveness of the Lighthouse Parenting Program, a mentalization-based intervention, in improving these outcomes. Thirty mothers were randomly assigned to an intervention group (n = 15) receiving 12 weekly sessions or a control group (n = 15). Standardized self-report measures—Parental Burnout Assessment, Childhood Trauma Questionnaire–Short Form, Parental Reflective Functioning Questionnaire, and Difficulties in Emotion Regulation Scale—were administered at pre-intervention, post-intervention, and three-month follow-up. Mixed-design ANOVAs revealed significant time × group interactions for all outcomes. Parental burnout decreased (F(1,28) = 29.91, p = .001, ηp² = 0.52), emotion regulation difficulties decreased (F(1,28) = 70.23, p = .001, ηp² = 0.46), and reflective functioning measures (pre-mentalization, certainty about mental states, interest and curiosity) increased (ηp² ranging from 0.48 to 0.82) in the intervention group compared to controls, with improvements maintained at follow-up. These findings indicate that mentalization-based parenting interventions effectively enhance parental outcomes in mothers with a history of childhood maltreatment.
