Overview

There will be 5 intakes (consisting of one CBT group and one CBTH group per intake) over a period of two years. Each intake will involve a pre-assessment period, then random allocation to treatment, followed by 10 consecutive weeks of group based treatment sessions delivered from 7pm-9pm. Each CBT and CBTH will receive the same core CBT treatment, delivered to each group on different nights during the same 10 week period. All groups will be followed up at post treatment, at 6 months and at 12 months.

Pre-assessments will be done via Zoom and online self report measures, and all face to face treatment will take place at the Robin Winkler Clinic, School of Psychological Science, at the University of WA. With pandemic protocols in place, all particpants will be encouraged to only attend sessions if healthy, and to observe social distancing when they do so. In the event of non-attendance due to illness or other reasons, shorter make-up sessions will be offered to participants in person or via zoom. Participants will be encouraged to complete weekly self report measures online. All online measures are completed anonymously using participant research numbers.

A specific CBT treatment manual will be developed for this study by the principal study investigator, who will also produce the hypnosis scripts. Home based practice will be set for all sessions and these relate to the themes covered in each session, along with listening to the recordings. Participants will be encouraged to use home based practice.

Each group based therapy session will last approx. 100 minutes (plus a midway break). Participants will receive a 'therapy file' which will contain weekly handouts covering the main themes for each treatment session, group exercise worksheets and self-report sheets (e.g. activity based self-monitoring forms, thought record forms), all of which have been specifically designed for this study.

The face to face treatment will be delivered to all groups by the principal investigator, who is an experienced clinical psychologist, with assistance from a co-facilitator (who will vary from group to group).

Fidelity assessments will be conducted on a randomly selected number of pre-assessment interviews and on a randomly selected number of CBTH and CBT treatment sessions.
Post treatment and follow up assessments will involve a combination of online self report measures and a short interview by a blinded research assistant using the MADRS (either via zoom or telephone).

The core treatment themes of each for the CBTH group are (same as the CBT group):

Session 1:
Welcome
COVID 19 management
Group rules and expectations
Psycho-education on Major Depression
Group Exercise: Why change? Roadblocks to change?

The only difference between the two treatment groups is the last 15-20 mins of each session. Following the core treatment (see above), the CBTH group will be given a different hypnosis based recording to listen to at the end of each session (drawing on the themes of that particular session), and at home in between sessions. These hypnosis recordings will be around 15-20 mins duration.

Treatment 2: cognitive behvaioural therapy group

The CBT group will receive exactly the same core therapy components as the CBTH group described above except that, instead of hypnosis script recordings, the CBT group will be played a recording of a Progressive Muscle Relaxation (PMR) procedure at the end of each ssession. They will be encouraged to listen to the PMR recording at home, as often as possible, in between sessions.

Purpose of the study

Treatment

Allocation to intervention

Randomised controlled trial

Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)

Randomisation allocation will not be performed by the PhD investigator who is conducting the clinical trial but by a co-supervisor whose only task (during recruitment, assessment and treatment phases) is to conduct the randomisation. Hence, the co-supervisor is blinded to all information regarding each participant other than their gender and if their mood block rating (high or low). Participant research numbers accompanied by gender and mood block ratings will be sent for randomisation. This information will be entered into a computer program and randomisation codes for the treatment arm each participant is randomly allocated into will be generated electronically.

Methods used to generate the sequence in which subjects will be randomised (sequence generation)

Participant randomisation will follow CONSORT guidelines (Boutron et al. 2008) and will make use of stratification with blocking. Randomisation will be stratified by level of depression and by gender so that each treatment group (block) is approximately equivalent in terms of depression severity and gender.

Efficacy

Statistical methods / analysis

The aim was to enrol up to n=120 participants. Based on other MDD treatment studies, an attrition rate of 15-25% is anticipated. Alladin and Alibhai (2007) is the only published study which tested the CBT vs CBTH paradigm for MDD. A G-Power analysis was performed on their data (using a two tailed test, with a = .05 and power = .80, on the post/12mth follow up treatment effect sizes of d = .48/.22 for Mood, d = .58/.71 for Anxiety and d=.68/.53 for Hopelessness). This analysis revealed that a total sample size of 27, 18 and 12 participants would have been required at post across the three measures, and 155, 11 and 23 participants respectively at 12mth follow up. Stated differently, a general effect size of d=.29 would have been required to achieve a statistically significant result on the completed sample of 84

However, given the impact of COVID19 on recruitment, we have been only able to enrol and randomly allocate 66 participants.

Statistical analyses of the primary and secondary dependent variables will be based on an intention-to-treat principle. Comparisons of CBT with CBTH at the same time intervals (weekly, then at post treatment, 6 month and 12 month follow up) will be calculated using a linear mixed-effects modelling, with restricted likelihood estimation, adjusted for baseline values of the variable under investigation.

Treatment effect sizes (Cohen’s d/dig) for the primary and secondary dependent variables will also be calculated and this will enable comparisons between the CBT and CBTH treatments.

Correlational analyses will be used to assess mediating and moderating variables.

Summary

Brief summary

The focus of this project is the treatment of adults with Major Depressive Disorder (MDD) using group psychotherapy. It will examine Cognitive Behaviour Therapy (CBT), an effective type of psychotherapy with outcomes comparable to if not better than medication. In spite of these results, only about 50% of depressed people improve with CBT, and many relapse.

Over the years, much effort has gone into exploring ways to improve treatment outcomes for MDD with CBT. Drawing on past and current research, this project combines various components of CBT into a unique and somewhat shorter treatment package.

This project aims to answer two key questions:
1. Does this 10 session CBT treatment, delivered in a group format, achieve comparable results with benchmark studies that have primarily used Behavioural Analysis, Cognitive Therapy or CBT treatment over more sessions?
2. Does CBT with the addition of hypnosis (CBTH) achieve better outcomes for MDD than CBT without hypnosis ?
