Study Overview
Brief Summary
This randomized clinical trial aims to evaluate the effects of mentalization-based group psychotherapy in patients diagnosed with anxiety and/or depression disorders. In total 100 users of mental health communitary services will be recruited for this study. Participants will be randomized in two parallel groups: to receive usual acceptance and commitment therapy group intervention (control group) or to receive brief mentalization-based group psychotherapy (intervention group). Participants in the trial will be assessed at baseline and at 3 months.
Detailed Description
QUALITY ASSURANCE PLAN. The researchers will review and report the process during the trial covering participant enrolment, consent and eligibility to protect participants, including reporting of harm and completeness, accuracy and timeliness of data collection.
STANDARD OPERATING PROCEDURES. Participants will be identified from community mental health services who meet all the study eligibility criteria (listed in section Eligibility). Participants will be recruited over a period of 20 months by mental health professionals (clinical psychology residents). Community sample for validation will be recruited by social media. Participants will not receive financial reimbursement for taking part in this trial.
DATA DICTIONARY. All variables collected in this study are listed and described in an electronic case report form, with associated guidelines, to ensure consistency in all gathered data. The following data will be collected in this trial:
Sociodemographical data. Anxiety symptoms: Generalized Anxiety Disorder 7-item scale (GAD-7) Depressive symptoms: Patient Health Questionnaire-9 (PHQ-9) Epistemic Trust: Questionnaire Epistemic Trust (QET) Epistemic Trust, Mistrust and Credulity: The Epistemic Trust, Mistrust and Credulity Questionnaire (ETMCQ).

Outcomes
Primary Outcomes
Change from baseline anxiety symptoms at 3 months.
Time Frame: At baseline then at 3 months.
Generalized Anxiety Disorder 7-item scale (GAD-7), is a self-report questionnaire used to assess the severity of generalized anxiety disorder symptoms. It consists of seven questions that ask respondents to rate how often they have experienced various anxiety-related symptoms over the past two weeks. Each item is scored from 0 (not at all) to 3 (nearly every day), allowing for a total score ranging from 0 to 21. Higher scores indicate greater anxiety severity. The Spanish adaptation used in this study has excellent psychometric properties, with a Cronbach's alpha of .94
Change from baseline depressive symptoms at 3 months.
Time Frame: At baseline then at 3 months.
Patient Health Questionnaire-9 (PHQ-9) is a self-report tool designed to assess the severity of depression symptoms. It consists of 9 questions using a Lykert-type scale from 0 (not at all) to 3 (nearly every day). Respondents are asked to rate how often they have experienced specific symptoms over the past two weeks. The total score can range from 0 to 27, with higher scores indicating more severe depressive symptoms.
Secondary Outcomes
- Satisfaction with therapy(At 3 months)
- Change from baseline epistemic trust at 3 months.(At baseline then at 3 months.)
- Change from baseline epistemic trust, Mistrust and Credulity at 3 months(At baseline then at 3 months.)
- Change from baseline reflective functioning at 3 months.(At baseline then at 3 months.)
- Change from baseline functional impact at 3 months.(At baseline then at 3 months.)
