About this trial
The goal of this clinical trial is to learn if a "blended" therapy format (combining face-to-face therapy sessions with a smartphone app) works to treat emotional disorders, such as depression and anxiety, in adults. It will also see if this blended format is feasible and acceptable for patients in primary care settings.
The main questions it aims to answer are:
Does the blended therapy format reduce symptoms of depression and anxiety?
Is the blended format as effective as standard face-to-face therapy?
Do participants find the smartphone app easy and helpful to use?
Researchers will compare the blended therapy group to a standard face-to-face therapy group and a wait-list control group to see if the blended approach works well.
Participants will:
Attend therapy sessions based on the Unified Protocol (a type of cognitive-behavioral therapy) for about 10 weeks.
Use a smartphone app to complete exercises and track their emotions (if assigned to the blended group).
Answer questionnaires about their symptoms and quality of life at the beginning, at the end of treatment, and 3 months later.

Treatments tested in this trial
Unified Protocol
BehavioralA transdiagnostic cognitive-behavioral intervention consisting of 8 modules targeting emotion regulation mechanisms. It includes psychoeducation, mindful emotion awareness, cognitive flexibility, countering emotional behaviors, and exposure exercises.
Treatment groups
Trial outcomes
Primary outcomes
Feasibility (Recruitment and Retention Rates)
Feasibility will be evaluated by tracking the recruitment rate (meeting the target of N=45 within the planned timeframe) and the retention rate. A success criterion is defined as ≥80% of participants in the intervention groups completing the study protocol.
Acceptability (Participant Satisfaction)
Assessed using items adapted from Branquinho et al. regarding the perceived usefulness of the intervention and preference for the format. Two key questions are asked: (1) Perceived usefulness (Yes/No) and (2) Preference for this type of treatment (rated on a 4-point scale from "No, I would refuse" to "Yes, I would prefer it"). Qualitative feedback on advantages/disadvantages is also collected.
Secondary outcomes
Change in Overall Anxiety Severity and Impairment Scale (OASIS) Score
The OASIS is a 5-item self-report measure designed to assess the frequency and intensity of anxiety symptoms, as well as avoidance and functional impairment related to anxiety. Items are rated on a 0-4 scale. The total score ranges from 0 to 20, with higher scores indicating greater anxiety severity and impairment.
Change in Overall Depression Severity and Impairment Scale (ODSIS) Score
The ODSIS is a 5-item instrument used to evaluate the frequency and severity of depressive symptoms and the resulting functional impairment. Items are rated on a 0-4 scale. The total score ranges from 0 to 20, with higher scores indicating greater depression severity and impairment.
Change in Multidimensional Emotional Disorder Inventory (MEDI) Score
A 49-item self-report inventory assessing 9 transdiagnostic dimensions of emotional disorders (neurotic temperament, positive temperament, depressed mood, autonomic arousal, somatic anxiety, social anxiety, intrusive thoughts, traumatic re-experiencing, and avoidance). Higher scores indicate higher levels of the respective dimension.
Change in Difficulties in Emotion Regulation Scale (DERS) Score
A 36-item self-report measure assessing emotion regulation deficits. It includes subscales like nonacceptance, goals, impulse, awareness, strategies, and clarity. Higher total scores indicate greater difficulty in emotion regulation.
