Évaluation de l’efficacité d’un programme d’entraînement parental pour les parents d’enfants souffrant d’anxiété de séparation

Separation anxiety disorder (SAD) is the most prevalent anxiety disorder among children. It appears early in development and has multiple negative consequences. Cognitive-behavioral therapy (CBT) has been shown to be an effective treatment for anxiety disorders. However, few studies have examined the efficacy of CBT to treat SAD in particular, and even fewer have examined the impact of this form of therapy on children younger than 7 years old. The main objective of the present doctoral thesis was to evaluate the efficacy of a CBT parent-training program, that was adapted specifically for parents of children aged 4 to 7 years old suffering from SAD. This study had two specific objectives: to observe any fluctuations in the child’s SAD symptoms during the treatment and to examine the impact of the program on parental variables. A single-case multiple baseline across-subjects design was used. Six families with a child aged 4-7 years old and with a diagnosis of SAD participated. Semi-structured interviews, self-reported questionnaires and daily diaries were used with the parents to assess the child’s anxiety symptoms, parental practices, parenting stress, and the parents anxious and/or depressive symptoms. Questionnaires on child problems were also sent to the children’ teacher or educator. All questionnaires were administered at three times of measurement (pre-treatment, post-treatment and 3 months follow-up). Daily diaries were also completed by the parents at baseline, throughout the treatment, and during one to two weeks at follow-up. Results revealed that five of the six children no longer met the criteria of a SAD diagnosis after treatment and three months later. Findings from the daily diaries showed a clear reduction of the principal SAD symptoms for half of the children but mixed results for the other half of the children and that four of six children presented a systematic favourable change of the total weekly frequency of SAD symptoms after the intervention. The results of parent questionnaires showed an improvement of SAD symptoms for four children at post-treatment and/or follow-up. The teacher/educator questionnaires indicated low impact of anxiety symptoms. The impact of the program on parenting stress and parental practices is mixed with some parents showing improvement and others less so. The results support the efficacy of the Programme d’entraînement parental pour les enfants souffrant d’anxiété de séparation (PEP-AS) to reduce SAD symptoms in preschool age children and support the relevance of directing the treatment towards parents and including a relational component in the intervention. However, more research is needed to replicate these findings with larger samples and randomized control trials. It would also be interesting to dismantle the program and to examine the various components of the treatment in different combinations, and to explore more specifically the program effects on parental variables.
