Brief Summary
This observational study investigates the outcomes of Strategic Psychotherapy, a form of brief psychological treatment focused on specific goals for change, co-constructed with patients. The aim is to evaluate whether patients who receive this therapy in private practice settings experience improvements in their psychological well-being, symptoms, and daily functioning. The study population includes all adult patients (≥18 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. Additional information will be collected, such as use of medication, the patient's own evaluation of the therapy, number of sessions attended, initial diagnosis, involvement of family members, and types of prescriptions used. All data will be treated confidentially and used solely for research purposes.

Outcome Measures
Primary Outcomes (1)
1. Symptom Checklist-90-Revised (SCL-90-R) 2. Clinical Outcomes in Routine Evaluation - Outcome Measure (CORE-OM)
1. Symptom Checklist-90-Revised (SCL-90-R) Description: A 90-item self-report scale assessing psychological symptoms across multiple domains. Each item is rated on a 5-point Likert scale (0 = "not at all" to 4 = "extremely"). Higher scores indicate greater symptom severity. 2. Clinical Outcomes in Routine Evaluation - Outcome Measure (CORE-OM) Description: A 34-item self-report questionnaire assessing well-being, problems/symptoms, functioning, and risk. Each item is rated on a 5-point scale (0 = "not at all" to 4 = "most or all of the time"). Higher scores indicate greater distress.
Baseline (prior to first psychotherapy session) and at end of treatment (average of 12-16 weeks, depending on number of sessions).

You may not qualify if:
- Individuals younger than 18 years.
- Patients with severe psychiatric conditions requiring immediate specialized care (e.g., acute psychosis, severe suicidal risk, substance dependence requiring detoxification).
