This study evaluated Evolve Therapeutic Services, an innovative Queensland, Australian programme employing a trauma-informed collaborative wrap-round model of care in combination with a flexible intervention approach that is individually tailored to children and young people in out-of-home care who present with complex and extreme behavioural and mental health problems. The sample consisted of 768 children and young people. Three measures, the Children's Global Assessment Scale, Health of the Nation Outcome Scales for Children and Adolescents and the Strengths and Difficulties Questionnaire were used to assess functioning via a pre-post treatment design. Outcomes were assessed by comparing pre and post-treatment mean scores using repeated-measures t-tests. For estimates of differences in the proportion of children and young people in the clinical range between pre and post-treatment the McNemar test was used. In addition, surveys were completed by carers and stakeholders. Results provided a demographic profile, clinical profile and pre and post-treatment comparisons. Results revealed significant improvements across a range of problem areas: general functioning and adjustment; antisocial behaviour; overactivity and poor attention; non-accidental self-injury; problems with scholastic and language skills; emotional symptoms; peer and family relationships; self-care and independence; and school attendance. Survey data supported the outcomes from the stakeholder-rated and carer-rated measures. Findings provide ongoing evidence for the effectiveness of the therapeutic intervention programme.
