Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Self-help behavioural activation (BA) remotely supported by telephone vs usual care.

Participants randomised to BA will be mailed a specifically-designed self help workbook titled "Helping you to maintain a positive mood in older age". The workbook is based on clear principles of an evidence supported psychological treatment for depression in later life. It outlines relevant information about depression and offers guidance on how to identify depressive symptoms and take action to improve mental wellbeing. In particular, the booklet outlines how to monitor activities, keep a balance between activities and recognise the connection between activity and mood.

To offer support to participants and optimise adherence to the intervention, a behavioural activation therapist will telephone participants on 3 occasions throughout the course of the 8 week program (first call within 2 weeks of randomisation than at week 4 and week 8) with a 4 week interval period between each call. The approximate duration of these telephone sessions will be 20-30 minutes and participants will be asked to complete activities from the workbook during the 4 week interval periods. The BA therapist will encourage participants to complete all relevant activities and participants can spend as much time as they wish completing each relevant stage through the work book.

Comparator / control treatment
Standard Medical Care - Usual care received from the participants General Practitioner and any other care the participant may be receiving from other services.

Control participants will receive a copy of the Behavioural Activation self-help booklet at the end of the study. This will be once the final participant recruited into the study has returned their 52 week follow up health & lifestyle questionnaire which assesses the severity of depressive and anxiety symptoms as measured by the Patient Health Questionnaire (PHQ-9) (Kroenke et al., 2001) and the brief measure for assessing Generalized Anxiety Disorder (GAD-7) (Spitzer et al., 2006).

Prevention
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
20,000 randomly selected men and women from the Western Australian electoral roll aged 65 years or over residing in regional and remote Western Australia will be posted a project information sheet, consent form, health screening questionnaire and replied paid envelope.

Respondents who return their questionnaires and respond in the affirmative to one of two of the “Whooley” questions contained within the screening questionnaire will be contacted by study staff to confirm eligibility, answer any questions and complete assessment for the presence of a Major Depressive episode utilising the SCID- I. The TICSm will also be administered to ascertain evidence of cognitive impairment.

Participants who meet study entry criteria including the presence of subsyndromal depression (as evidenced by their affirmative answer to one of the Whooley questions and because they do not fulfill criteria for the diagnosis of a Major Depressive episode according to the SCID 1), will be randomly assigned to one of two groups:

Standard Medical Care or Standard Medical Care and Behavioural Activation Intervention

Due to the nature of the study, participants in the intervention group and the behaviour therapist facilitating their efforts will not be blinded to group allocation. Research staff assessing end points (SCID-1) will be blinded and will not have access to information detailing the participant's group status.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Group allocation will occur according to a list of random numbers generated by computer. The list will be generated and centrally maintained by the University of Western Australia's Centre for Software Practice, which will have no direct contact with participants.

Efficacy
Statistical methods / analysis
All analyses will follow CONSORT guidelines. We will use standard descriptive statistics to compare basic sociodemographic and clinical data across treatment arms. We will examine the proportion of participants in each study group who converted to a Major Depressive Episode over the 52 week follow up period with analysis of contingency tables and logistic regression. We will use imputation methods (ICE) to examine the primary outcome on an intention-to-treat basis. Multilevel mixed models will be employed to investigate changes in PHQ-9, GAD-7 and SF-12 scores over 52 weeks.
