To conduct a pilot randomized controlled trial (RCT) of a culturally adapted Unified Protocol (UP) for transdiagnostic psychological treatment in adults (age 18 and above) with anxiety and/or depression to assess the feasibility and acceptability of UP treatment.
The main questions it aims to answer are:
The participants will be randomized to either the treatment group or the control group. The treatment group will receive 14 sessions of one-on-one individual treatment with the Unified Protocol. The control group will receive no treatment.
Most patients with depression and anxiety in low-resource settings don't get evidence-based treatment. Transdiagnostic approaches like UP are promising for these settings because they are multi-problem, modular, flexible, and have low complexity. The present study aimed to investigate the initial acceptability and feasibility of the adapted Unified Protocol (UP) in relation to its quantitative and qualitative effects on attendance, homework compliance, satisfaction, and perceived usefulness of the intervention. Additionally, the study aimed to evaluate the preliminary effects of the adapted UP on depression, anxiety, functional impairment, and emotion regulation among adults suffering from anxiety, depression, and/or comorbidity of both disorders.
A sample size of approximately 50 adults will be recruited from mental health facilities and online dissemination of the study. After screening through the Beck Depression Inventory-II (BDI-II) and Beck Anxiety Inventory (BAI), and assessing the inclusion and exclusion criteria, those who demonstrate moderate to severe scores on the BDI-II and BAI will be further evaluated by the principal investigator using the Structured Clinical Interviews for DSM-5 (Research Version) (SCID-5-RV) to determine their diagnosis. Once the eligibility criteria are met, participants will be randomly assigned to one of two study conditions:
Experimental group: Participants in the experimental group will receive the Unified Protocol (UP) treatment.
Control group: Participants in the control group will be placed on a waitlist and will not receive any treatment until the end of the study.
Participants from both groups will complete several assessment measures at baseline, mid-treatment (only at week 7 of the UP), and post-treatment.
To ensure protocol quality and fidelity, the therapist has a master's degree in Clinical Psychology and two years of previous supervised clinical experience in cognitive behavioral therapy (CBT). The therapist also participated in introductory and intermediate-level training workshops for the Unified Protocol (UP) and received UP Therapist Certification. The therapist has received supervision from the UP-certified psychologist and received 18 weeks of individualized supervision on a course of treatment utilizing the UP. Weekly supervision sessions were conducted via video-conferencing (Zoom), and transcripts of the sessions were reviewed for adherence to the protocol and competence in protocol delivery throughout the course of treatment.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Experimental group: Unified Protocol (UP) | Experimental | Participants will receive 14 weekly individual sessions of 50-60 minutes each using the adapted UP treatment. |
|
| Control group: Waitlist Control | No Intervention | Participants in the control group will be placed on a waitlist and will not receive any treatment until the end of the study. |

| Unified Protocol for Transdiagnostic Treatment of Emotional Disorders | Behavioral | The current researchers adapted the Unified Protocol (UP) treatment and used the adapted version in this study. UP outlines two complimentary modules for goal setting and psychoeducation followed by five core treatment modules: mindful emotion awareness, cognitive flexibility, countering emotional behaviors, awareness and tolerance of physical sensations, and emotion exposures, and an optional relapse prevention module to help people maintain their gains after treatment. |
| Measure | Description | Time Frame |
|---|---|---|
| Feasibility- Recruitment method | The number of participants recruited by each of the three methods used for recruiting. The methods will be: mental health facilities, online dissemination, and referrals and recommendations. | 14 weeks |
| Feasibility- Recruitment rate | To assess the estimates of likely recruitment rates, including: How many participants approached? How many participants volunteered? How many participants were screened? How many participants were retained in the study? What was the dropout rate? The number of participants completing the final assessment (assessed through a record made at each session). | 14 weeks |
| Feasibility- Weekly face-to-face sessions | The nature of barriers that may lead to participants dropping out of treatment can be assessed by examining the number and type of problems that they experienced while attending weekly sessions. These problems include transportation difficulties, work or educational demands, childcare difficulties, scheduling conflicts, and treatment procedures interfering with daily life. Followed by an open-ended question that will assess any other reason to discontinue the treatment. | 14 weeks |
| Feasibility: Eligibility criteria | Assessed through the number of participants fulfilling the eligibility criteria from the total number of participants registered, number of ineligible participants, and reasons for ineligibility. | 14 weeks |
| Feasibility - Treatment adherence and engagement | Engagement in treatment will be assessed using the Homework Rating Scale-Revised, a 12-item measure that assesses beliefs, consequences, and engagement with treatment homework activities. Total scores range from 0 to 48 on this scale, where higher scores indicate higher commitment to the treatment. Treatment adherence will be further assessed by tracking participant attendance, percentage of intervention completion, and number of sessions completed. |
| Measure | Description | Time Frame |
|---|---|---|
| Beck Depression Inventory-II | It is a 21-item self-report questionnaire to assess depressive symptoms with scores ranging from 0 to 3. Higher scores indicate worse depressive symptoms. | 14 weeks |
| Beck Anxiety Inventory |
| Measure | Description | Time Frame |
|---|---|---|
| Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders-5, the Research Version | The Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders-5 is a semi-structured interview guide for making the major Diagnostic and Statistical Manual of Mental Disorders-5 diagnoses. The current study is using this scale to ensure that all of the study subjects have symptoms that meet the DSM-5 criteria for Major Depressive Disorder and/or anxiety disorder and that all of the subjects with Substance Use Disorder, Bipolar Disorder, or Psychotic Disorders are excluded. The items are scored on a scale of 1 to 3. A higher score on this scale suggests the presence of a mental condition. |

To ensure blinding of participants and intervention facilitator, a randomizing researcher, who is different from the facilitator, will generate the sequences and assign an ID (1-50) to one of the groups based on the sequence. The sealed envelopes will be given to the facilitator, who will open the envelope in the interview and inform the participants about their allocated group. This will ensure that neither the participants nor the facilitator will know which group they are assigned to, which will help to minimize bias in the study.
