Long-term efficacy of an attachment-based parental training program for single mothers and their children: a randomized controlled trial.

Objective: Single mothers suffer more frequently from chronic diseases, depression, and elevated stress level. Their children display adaptation and behavior problems more often than children of dual-parent families. To prevent these risks, a parental training program (PALME) for single mothers and their preschool children was developed. The concept of PALME is based on attachment theory and psychodynamic-interactional approaches. Subject and methods: The efficacy of the program was evaluated in a randomized control intervention study with 58 single mothers. Outcomes from the revised version of the Symptom Checklist SCL-90-R, SF-12 Health Survey, Psychogenic Impairment Score (BSS), Scales on the Experience of Emotions (SEE) and Strengths and Difficulties Questionnaire SDQ were compared at baseline (t1), post-treatment (t2), and 6 months follow-up (t3) for statistical and clinical significance. Per-protocol analyses of variance were used to examine intervention effects. Results: Statistically significant group x time interaction effects in favor of the intervention group indicated intervention effects on the mothers' psychological symptom load GSI score of SCL-90 R, depression, psychological well-being and psychogenic impairment. Some aspects of maternal emotional competence and behavioral problems of their children improved only in the short term. Conclusion: The results suggest that PALME is an effective prevention program for the reduction of maternal depression and psychological symptom load and the improvement of well-being among single mothers.
