Psychological Outcomes of Strategic Therapy in Adult Outpatients (POST Trial)

Официальное название

A Naturalistic Study of Psychological Outcomes in Adult Outpatients Receiving Strategic Psychotherapy in Private Practice (POST)

Обзор

This observational study investigates the outcomes of Strategic Psychotherapy, a form of brief psychological treatment focused on specific goals for change. The aim is to evaluate whether patients who receive this therapy in private practice settings experience improvements in their psychological well-being, psychological symptoms, and daily functioning. The study population includes all adult patients (≥16 years) who spontaneously seek treatment from two strategic therapists between January 2021 and December 2025. Eligible participants must present with psychological problems that meet the criteria for a clinical diagnosis. Participants will complete two psychological questionnaires (SCL-90R and CORE-OM) before starting therapy and again at the end of their treatment. Changes in scores on these outcome measures will be statistically compared with data from a non-clinical population to assess whether the observed changes are greater than would be expected by chance. Additional information will be collected, including medication use, the patient's own evaluation of the therapy, the number of sessions attended, the initial diagnosis, family involvement, and the types of therapeutic prescriptions used.

Подробное описание

Strategic Psychotherapy is a brief, goal-oriented form of psychological treatment that emphasizes the collaborative formulation of specific therapeutic goals and the implementation of targeted interventions to facilitate change. Despite its widespread clinical application, systematic evidence regarding patient outcomes in naturalistic private practice settings remains limited.

This observational study aims to contribute to the evidence base by examining the effectiveness of Strategic Psychotherapy in improving psychological well-being, reducing psychological symptom distress, and enhancing everyday functioning. The study includes all patients aged 16 years or older who independently seek treatment from two certified strategic therapists between January 2021 and December 2025. Eligibility is based on the presence of clinically significant psychological problems consistent with a formal clinical diagnosis.

Treatment outcomes will be compared with those of a non-clinical control group whose participants are assessed using the same outcome measures over a follow-up period of equivalent duration, in order to determine whether the observed changes in the clinical sample exceed those expected in the absence of psychological treatment.
