Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
A one-hour one-on-one session per week for 12 weeks using manualised CBT based on the empirically validated CBT program for older age anxiety and depression, Ageing Wisely. The enhanced CBT program teaches the same CBT skills as the standard CBT program, but with a stronger focus on bolstering social participation and connections within those skills. That is, in the enhanced CBT program, standard CBT techniques such as goal setting, activity scheduling, and graded exposure, are specifically focused around social connections, maximising family and community support, and social contribution. Modules of social connection are integrated into the standard CBT program and module length varies from session to session.

Treatment is delivered by Clinical Psychologists and Clinical Psychology registrars, supervised by Chief Investigators to ensure treatment adherence. Adherence of participants to treatment will be monitored with 20% of the sessions coded for fidelity by an independent rater.

Behaviour
Comparator / control treatment
Standard CBT: one-hour one-on-one session per week for 12 weeks using the empirically validated CBT program for older age anxiety and depression, Ageing Wisely. This program includes generic CBT skills such as psycho-education, problem-solving, cognitive restructuring, sleep hygiene, and graded exposure which is a core skill for treatment of anxiety, and activity scheduling which is a core skill for the treatment of depression.

The two programs differ in that the enhanced program has a stronger focus on bolstering social participation and connections within those skills relative to the standard CBT program.

Study design
Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Eligible participants will provide informed consent and will subsequently be randomised to receive the standard CBT or Enhanced CBT in a 1:1 ratio. A statistician (independent of the research team) will create the randomisation schedule to allocate individuals to condition. Block randomisation will be used to ensure that the two comparison groups are the same size. Due to the nature of randomisation, clinicians and participants will not be blinded to condition.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
The randomisation schedule will be generated using a computerised randomizer (www.randomizer.org) and placed into consecutively numbered sealed envelopes.
Masking / blinding

Efficacy
Statistical methods / analysis
Data will be analysed using intention-to-treat principles. All participants will be included in analyses based on the condition to which they were initially allocated. Multiple imputation will be used to manage missing data. The efficacy of the programs will be established using mixed model analysis to compare the mean differences in clinical diagnostic severity (established by clinicians who are blind to treatment allocation) and scores on self-report measures at pre-treatment, post-treatment, and at a 12-month follow-up period.

Analysis will be a mixed model with random subject effect, fixed effects relating to group allocation (between-group), time (within-subject) and covariates. Interaction contrasts will be used if the time x group interaction reaches statistical significance, but the main effect contrast will be used if not.

An economic evaluation will be conducted from the healthcare system perspective. Health outcomes captured through the AQoL-8D will be evaluated using Quality Adjusted Life Years (QALYs). Intervention and resulting costs per patient in the enhanced CBT group will be compared against those in the standard CBT group, and include acute care, primary care, mental health care, community care, and medication use.

Summary
Brief summary
The aim of this study is to evaluate the efficacy and cost-efficacy of a psychosocial intervention to treat emotional symptoms and increase social participation in anxious and/or depressed older adults, relative to current “best practice” transdiagnostic CBT. We predict that the enhanced program will lead to significantly greater reductions than the standard program on our primary outcome, diagnostic severity of anxiety and depression.
