Abstract
Although self-help parent management training represents an effective form of treatment with low barriers for families, little is known about how change is induced. The present thesis analyzed treatment components and process mechanisms of telephone-assisted self-help parent management training with a behavioral basis and a nondirective basis for child externalizing behavior problems. In a randomized controlled trial, parents of children aged 4 to 11 years with externalizing behavior problems were allocated to telephone-assisted self-help parent management training with a behavioral basis or a nondirective basis, including self-help booklets and therapist consultations via telephone. The per-protocol sample included 108 families. Based on existing measures and predefined psychometric criteria, the Therapist Intervention Scale (TIS) was developed to analyze treatment components in the self-help booklets and the audiotaped telephone consultations. Furthermore, a potential mediating effect of therapist behavior on child outcomes was examined. From an exploratory perspective, parental adherence was analyzed as a potential sequential mediator following therapist behavior. Exploratory factor analyses suggested the formation of the TIS scales Guidance & Structures as well as Relationship & Emotions. Reliability indices were acceptable to excellent. Indices for construct validity were mostly in line with the hypotheses. As expected, therapists and booklets showed a stronger emphasis on guidance and structures in the behavioral intervention and a stronger emphasis on the emotions and relationships in the nondirective intervention. Furthermore, the findings suggest that the group effect on child attention-deficit/hyperactivity disorder severity and functional impairment was mediated by therapists’ emphasis on emotions and relationships in the nondirective intervention. The exploratory sequential mediation analyses indicated a potential sequential mediation effect of parental adherence following therapist behavior. We did not find a mediation effect for therapists’ emphasis on guiding and structuring or for the behavioral intervention. In conclusion, the analyses support the reliability as well as the validity of the self-developed TIS scales. In accordance with their theoretical basis, the two interventions showed distinct treatment profiles. The findings underline the importance of therapists’ emphasis on emotions and relationships for change in child outcomes as a potential unique process mechanism in the nondirective intervention and complement findings on process mechanisms of the behavioral intervention. Future research might analyze additional mediators of change and include potential moderators in one model, which might deepen our understanding of the process mechanisms underlying treatment approaches.
