Abstract
BACKGROUND: Symptoms of anxiety and depression are prevalent in older adults. AIMS: To compare clinician-guided and self-guided versions of a transdiagnostic internet-delivered cognitive-behavioural therapy (iCBT) intervention for adults aged 60 years and above. METHOD: Adults (n=433) with symptoms of anxiety and depression were randomly allocated to: (1) clinician-guided treatment (n=153); (2) initial clinician interview followed by self-guided treatment (n=140); or (3) self-guided treatment without interview (n=140). RESULTS: Large reductions (d ≥1.00) in symptoms of depression and anxiety were observed across groups, and sustained at follow-up. No differences were observed in clinical outcomes or satisfaction ratings. Age did not affect outcomes. CONCLUSIONS: Carefully developed iCBT interventions may significantly reduce symptoms of anxiety and depression in older adults when delivered in either clinician-guided or self-guided formats.
