Aims and objectivesThe aim of this study was to evaluate the effectiveness of therapeutic conversation intervention in group and caregiver sessions on the supporting role of caregivers. BackgroundCaregivers of people with eating disorders are known to suffer major difficulties and are in great need of support. Unhelpful parental support strategies can delay the recovery of an individual with an eating disorder. Skill training interventions can equip parents with skills, guidance and techniques by helping them to be a support person and making them one of the most important links in the treatment process. DesignThe therapeutic conversation intervention consisted of five group and caregiver sessions and three booster sessions. The Calgary Family Assessment and Calgary Family Intervention Models, the Illness Beliefs Model and the New Maudsley Method were used as theoretical frameworks. The content of the intervention consisted of work on difficult behaviours, feelings and helpful strategies. The participants (n=58) included primary and secondary caregivers of 12- to 24-year-old patients with eating disorders. Eight caregivers dropped out of treatment. MethodsThis study had a quasi-experimental design with one pre- and two post-test measures. ResultsBetween 90-96% of caregivers rated the therapeutic conversation intervention as supportive. Furthermore, the study revealed significant differences in caregiver emotional and cognitive support, illness beliefs, disruptive behaviour and quality of life, negative aspects of care giving demands and caregiver and patient behavioural difficulties after the intervention and/or at follow-up. ConclusionsTherapeutic conversation intervention with caregivers in group and private sessions proved to be beneficial. Relevance to clinical practiceThis outcome provides information for healthcare professionals on how they can help primary caregivers in their supporting role, which can, in turn, improve services in healthcare centres and psychiatric hospitals.
