Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The immediate treatment group will receive treatment consisting of 50-minute weekly appointments, delivered over eight weeks. This treatment is based on the manual for the Unified Protocol (Barlow et al., 2018), and each of the eight modules will be delivered over videoconferencing in eight one-on-one sessions. The typical eight-module treatment will cover: psychoeducation on the CBT model and goals; mindfulness of emotions; building cognitive flexibility with restructuring; addressing emotional avoidance and emotion-driven behaviours; behavioural exposures/experiments; and relapse prevention.

Clients will be assigned therapeutic activities to complete in between sessions, as per standard practice in previous trials (Pachankis et al., 2015; Pachankis et al., 2020; Pachankis et al., 2023). Between-session therapeutic tasks may involve completing thought monitoring forms, doing mindfulness exercises, completing behavioural experiments or exposures, and so on. Each activity is typically short, taking approximately 5 - 30 minutes, and will differ from week to week. The time expected to be spent on these activities will depend on client goals and presenting problems and is unlikely to exceed three hours per week.

The treatment provided in the trial will be delivered by generally registered psychologists or provisionally registered psychologists. All clinicians will provide treatment while under the supervision of a clinical psychologist experienced in delivering treatments for anxiety and related disorders. The project investigators will provide training in delivery of the treatment protocol, and all clinicians will receive regular clinical supervision. To monitor treatment fidelity, at least 10% of session recordings will be randomly selected for review by a study investigator.

Additionally, eight to ten participants will be invited to participate in a qualitative interview to evaluate intervention acceptability from both the immediate intervention group and control group (after commencing treatment), with a total of 16 – 20 participants. This sample size is consistent with previous studies in this area of research (Jackson et al., 2022; Pachankis et al., 2020). Participants will be selected based on a representative matrix that aims to achieve a maximally diverse sample, as per previous studies (Christensen et al., 2023). Participants will be interviewed by a member of the research team who did not provide the treatment wherever possible. To encourage candid feedback, the benefits of honest feedback from participants for improving the intervention will be discussed early on during the interview. To encourage candid feedback, the benefits of honest feedback from participants for improving the intervention will be discussed early on during the interview. The interview will be audio recorded to assist with transcription and is expected to take approximately 30 to 60 minutes.

Behaviour
Comparator / control treatment
After an eight-week waitlist period, the control group will also receive eight weekly 50-minute sessions delivered one-on-one via video-conferencing. This treatment is based on the LGBTQ-Affirmative adapted version of the Unified Protocol (Pachankis et al., 2022). The intervention will still consist of the essential elements of the immediate intervention group’s treatment but includes adaptions based on previously conducted qualitative interviews with LGBTQ+ stakeholders and therapists with experience working in the LGBTQ+ community (Pachankis et al., 2015).

The adaptations centralise minority stress in treatment by considering it as a key maintaining factor in the client’s presenting problems and anxiety disorder symptoms (Hatzenbuehler, 2009; Meyer, 2003). It does this by prioritising the installation of skills to cope with minority stress, such as assertiveness and minority stress-informed psychoeducation. The adaptation also targets minority stress-based thoughts and core beliefs. For each skill provided in the original UP, the LGBTQ-adapted UP provides examples and/or case vignettes that are minority stress-based to emphasize that the skills learned in cognitive behavior therapy can be applied and used to deal with minority stress. For example, one vignette in the cognitive flexibility module asks participants to identify their automatic interpretations of an ambiguous mock text exchange in which an LGBTQ+ person makes a last-minute request to bring their new partner to an open-invite event but has no response from their friends.

The treatment will cover psychoeducation on the CBT model and goals; understanding the nature and emotional impact of LGBTQ-related stress; mindfulness of emotions; building cognitive flexibility with restructuring; addressing emotional behaviours; behavioural exposures/experiments; and relapse prevention. As in standard CBT practice and in the immediate intervention group, participants will be asked to complete therapy-related tasks between sessions.

The treatment provided in the trial will be delivered by generally registered psychologists or provisionally registered psychologists. All clinicians will provide treatment while under the supervision of a clinical psychologist experienced in delivering treatments for anxiety and related disorders. The project investigators will provide training in delivery of the treatment protocol, and all clinicians will receive regular clinical supervision. To monitor treatment fidelity, at least 10% of session recordings will be randomly selected for review by a study investigator.

Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
In this study, allocation will not be concealed, due to the nature of psychology treatment. Randomisation occurs after assessment and randomisation will be conducted by the Chief Investigator using a random number generator.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Randomisation will be conducted using a random number generator via the website www.random.org to ensure unbiased selection.

Summary
Brief summary
The purpose of this study is to examine the efficacy, feasibility, and acceptability of videoconferencing-delivered CBT for anxiety disorders in LGBTQ+ adults. A CONSORT-R compliant, two-group, randomised control feasibility trial (RCT) will examine the research questions. The hypotheses for this study are below:
1) Videoconferencing-delivered, standard CBT will result in significant reductions in symptoms with a large between-group and within-group effect size at post-treatment and three-month follow-up.
2) Videoconferencing-delivered, LGBTQ-adapted CBT will result in a similar degree of symptom reduction when compared to standard CBT.
3) Videoconferencing-delivered standard CBT and LGBTQ-adapted CBT will be feasible to deliver to LGBTQ+ adults with diagnosed anxiety
4) Videoconferencing-delivered CBT will be acceptable to LGBTQ+ adults with diagnosed anxiety disorders
