Transdiagnostic Treatment of Emotional Disorders for Women in a Homeless Situation

Study Overview
=================
Brief Summary
-----------------
The aim of this study is to assess the effectiveness and feasibility of an adaptation of the Unified Protocol (UP) for Transdiagnostic Treatment of Emotional Disorders to women living homeless in Madrid, Spain. To address this goal, both clinical and psychosocial outcomes will be measured. The application of the UP is postulated as an effective tool for improving mental health and well-being of women in a homeless situation, which in turn will enhance their social inclusion process.

Detailed Description
-----------------
The European Strategy for the Homeless People states that homelessness is the most extreme form of poverty and exclusion, which violates human dignity and poses a risk to health and life. Women constitute a particularly vulnerable subgroup among homeless people. Women living homeless show significant deterioration in their psychological welfare and mental health, which, among other aspects, is an obstacle in the access to care resources and inclusion processes. There is a growing interest in the effectiveness and efficiency of intervention techniques to address mental health problems. The high comorbidity between mental health disorders, and especially emotional disorders, has promoted the development and consolidation of a transdiagnostic perspective. This perspective raises the existence of common mechanisms involved in the maintenance of different disorders, so that there would be a preamble to cognitive and/or behavioral processes shared by various psychological disorders. The design of a transdiagnostic treatment strategy allows a more inclusive approach to mental health and facilitates the design of similar treatment programs applicable to a wide range of mental disorders. Therefore, the transdiagnostic treatment could be a feasible and effective alternative to address some of the most common problems in mental health among women in a homeless situation. This approach could be useful to improve a diversity of symptoms in the own context of homeless living women and facilitate a systematic evaluation of its effectiveness. The overall objective of this project is the development of a feasible and effective intervention adapted to the needs of women in a homeless situation and the service resources where they are attended. Moreover, the project aims to compare the group versus individual delivery of the UP among women in a homeless situation. This research is based on the hypothesis that the UP adaptation, both in group and individual delivery, will be effective in reducing anxiety and depression symptoms, decreasing negative affect and increasing psychological well-being, health state, positive affect, social support and quality of life. Strengths but also barriers and difficulties encountered in each format of intervention will be examined. This knowledge will be key to develop specific and adapted materials that enable effective interventions practices in the services resources for homeless people. The UP intervention will consist of 12 weekly sessions lasting an hour and a half, applied in different centers for homeless people in Madrid. There will be several assessment moments: before the intervention, twelve intersession assessments (i.e., one per session), after the intervention, and 3 months, 6 months and 9 months follow-ups. The psychological intervention will be carried out by therapists with a background in psychology. With this research it is expected to achieve results with impact at the technical level (in the design of effective interventions for psychological treatment of women in a homeless situation), on a scientific level (expanding knowledge about the effectiveness of intervention programs for women in social exclusion situations), and, especially, at the social level (affecting the quality of life and the processes of social inclusion of women in a homeless situation).

Design Details

Primary Purpose: Treatment
Allocation: Non-Randomized
Intervention Model: Parallel Assignment
Interventional Model Description: All women in a homeless situation attending any of the collaborating shelters will be asked to participate in the present study. Once inclusion criteria are met, each participant will be assigned to experimental condition or control condition. This research is composed by two sequential studies. The first study will deliver the UP in a group format, while the second study will deliver the UP on a one-to-one basis. Since these studies will not be performed concurrently, women will be assigned within each study to intervention or control condition. In the first study, participants will be assigned to one of two conditions: experimental condition (Unified Protocol, UP in group delivery) or waitlist control condition (WLC). In the second study, participants will be assigned to one of two conditions: experimental condition (Unified Protocol, UP in individual delivery) or control condition (WLC).

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Unified Protocol Transdiagnostic Treatment Emotional Disorders<br>An adaptation of the Unified Protocol for Transdiagnostic Treatment of Emotional Disorders (UP) to women in a homeless situation will be implemented in public shelters setting in Madrid, Spain. The UP adaptation is an intervention based protocol for emotional disorders, consisted of 12 treatment sessions of one and a half hours of duration each, at a rate of one per week. | Behavioral: Unified Protocol for Transdiagnostic Treatment of Emotional Disorders (UP)<br>* The Spanish Version of the Unified Protocol for the Transdiagnostic Treatment of Emotional Disorders for Homeless Women. The protocol contains five modules: (1) mindful emotion awareness, (2) cognitive flexibility, (3) countering emotional behaviors, (4) recognizing and confronting physical sensations, and (5) emotion exposures. This adaptation of Unified Protocol is organized in twelve sessions: Emotional disorders and emotional regulation; Motivation for change; Understanding the role of emotions; Mindful emotion awareness, Cognitive flexibility, Understanding and confronting physical sensations, Countering emotional behaviors, Emotional avoidance, Emotion exposure; Achievement recognition and look to the future; and Relapse prevention and closure.<br>|
| Other: Waitlist Control condition<br>The participants assigned to the waitlist control condition will not immediately receive the intervention. They will wait for 3 months, which is the duration of the intervention in the experimental group. After that time, they will be offered the same psychological treatment as those assigned to the UP (experimental condition). | Behavioral: Same than experimental condition (UP), after it finishes<br>* The Spanish Version of the Unified Protocol for the Transdiagnostic Treatment of Emotional Disorders for Homeless Women.

| Change in the Beck Depression Inventory (BDI-II) (Beck, Steer, & Brown, 1990); Spanish adaptation (Sanz, Navarro, & Vázquez, 2003) at pre, post intervention and at 3, 6 and 9 month follow-ups. | The BDI-II is a 21-item self-report measure designed to assess depression severity. Each item is rated from 0 to 3 with a total score of a maximum of 63 points. The Spanish version has shown good internal consistency (α = 0.86). | Up to 9 months | 
| Change in the Beck Anxiety Inventory (BAI) (Beck, & Steer, 1993); Spanish adaptation (Magán, Sanz, & García-Vera, 2008) at pre, post intervention and at 3, 6 and 9 month follow-ups. | The BAI is a 21-item self-report measure designed to assess anxiety severity. Each item has a 4-point severity scale (e.g., not at all, mildly, moderately, and severely), addressing symptoms experienced during the past week. The internal consistency of the Spanish version has been found to range from .85 to .94. | Up to 9 months | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |

Each item has a 5-point severity scale (e.g., not at all, mildly, moderately, quite a lot, and severely) with a total score from 20 to 100. The internal consistency of the Spanish version was .92 for positive affect subscale and .88 for negative affect subscale. | Up to 9 months | 
| Change in the Pemberton Happiness Index (PHI) (Hervás & Vázquez, 2013) at pre, post intervention and at 3, 6 and 9 month follow-ups | The PHI is a 21-item measure designed to assess integrative well-being using a scale from 0 (fully disagree) to 10 (fully agree) in the first 11 items and dichotomy answers (yes/no) in the last 10 items. It includes two subscales: remember well-being (general, hedonic, eudaimonic, and social well-being) and experienced well-being. Cronbach´s alpha of Spanish version was .84. | Up to 9 months | 
| Change in the Short-Form Health Survey Health Questionnaire (SF-12) (Ware, Kosinski, & Keller, 1996); Spanish adaptation (Vilagut et al., 2008) at pre, post intervention and at 3, 6 and 9 month follow-ups | The SF-12 is a generic health status instrument with 12 items, and eight subscales (physical functioning, role physical, bodily pain, general health, vitality, social functioning, role emotional and mental health). These eight subscales can be combined into two scores for physical health (PH) and mental health (MH), and a total score, ranged from 0 to 100, where higher scores reflect better self-reported health. The internal consistency of the Spanish version was α = .85 for PH and α = .78 for MH. | Up to 9 months | 
| Change in the Social Support Questionnaire (SSQ) (Sarason, Sarason, Shearin, & Pierce, 1987); Spanish adaptation (Martínez-López et al., 2014) at pre, post intervention and at 3, 6 and 9 month follow-ups. | The SSQ is a 6 items measure of social support.
