Description of intervention(s) / exposure
Intervention:
Group Schema Therapy is an established evidence-based protocol by Farrell & Shaw (2012) incorporating cognitive, behavioral and experiential techniques that focus on both group processes and tasks, whilst simultaneously being both efficient in use of resources. Consistent with published protocols (Straarup et al., 2022; Farrell & Shaw, 2014; Farrell, Shaw & Webber, 2009), concepts covered in the adapted group schema therapy program will include introduction to schema and modes, case formulation, and interventions for coping styles, modes and symptoms (education sessions, imagery work, chair work, cognitive and experiential exercises).
Procedure:
After initial contact is made, participants will be sent information statement and consent forms, and given the opportunity to discuss and ask questions before providing informed consent. Consent will be provided via the the secure web platform REDcap. Participants will be screened against the eligibility criteria using the Diagnostic Interview for Anxiety, Mood and OCD and Related Neuropsychiatric Disorders Screener (DIAMOND; Tolin et al., 2016), over the phone or in person or via videoconferencing software (Zoom). If they do not meet criteria, referral options and recommendations will be provided to them.
They will then be invited to come in for a short pre-treatment session (60-90 minutes).
Pre-treatment session: Interview to obtain mental health history, treatment goals, setting up group therapy expectations.
Following which, participants will participate in the 18 week group schema therapy program and complete routine outcome measures. Adherence will be monitored by attendance. Upon completion of the program, participants will be invited to participate in an interview to elicit feedback about the program.
Intervention Delivery:
Duration: 120 to 150 minutes for 18 weeks.
Group size: Group upto 11 participants.
Intervention will be delivered weekly for 18 sessions by licensed clinical psychologists and/or clinical psychology registrars registered by Australian Health Practitioner Regulation Agency.
Mode: Group therapy; Delivered in person at an approved site of The University of Sydney, Australia.
Post-treatment interview:
Participants would be invited to participate in an interview (60-90 minutes) post participation in the program. Semi-structured interview would be used to understand participant experiences and feasibility of the program. Interviews would be conducted by members of the research team and will be audio-recorded to aid in transcription and data analysis.
