ABSTRACT
OBJECTIVE: To examine rates and predictors of attrition from referral through to treatment completion in an outpatient public psychology service's eating disorder program in Perth, Western Australia. METHOD: The proportion (number) of clients (N = 671; mean age = 23.8 years) transitioning between stages of pre-treatment and treatment was identified. Associations between demographic, treatment and clinical variables and attrition were investigated using logistic regression. RESULTS: Only 34% (n = 230) of referred patients started treatment and 16% (n = 107) completed treatment. Referral acceptance was correlated with provisional diagnoses that meet the service's inclusion criteria, and attendance at an initial assessment was correlated with younger age. Treatment commencement was correlated with the presence of a co-occurring depressive or anxiety disorder, and no previous suicide attempts. Completing a full course of treatment was correlated with no previous hospitalisation for psychiatric issues, no previous suicide attempts, a history of psychiatric medication use, and treatment with family-based therapy. DISCUSSION: High rates of attrition were found from referral to treatment completion. A suggested framework for defining the different stages of attrition is proposed to allow for consistency of attrition reporting across the mental health field. Future studies are needed to identify why clients disengage following referral, assessment, and treatment commencement, to inform strategies to engage and sustain engagement and to optimise outcomes.
