Practice-Based Evidence in Psychotherapy: A Multicentric Study From Ecuador

The CORE-OM is a 34-item self-report instrument designed for use across heterogeneous services and grounded in a pan-theoretic core of psychological distress, including subjective well-being, problems, risk, and functioning. Items are scored on a scale from 0 (never) to 4 (always or almost always). Higher scores indicate greater psychological distress. This instrument is suitable as an initial assessment tool and as an outcome measure. The Spanish version of this measure will be used. This version was translated in Spain and has shown good psychometric properties in Spain and Ecuador. CORE-OM is administered to adult clients.

The CORE-10 is a generic, short, and easy-to-use assessment measure. Its items were drawn from the CORE-OM. The CORE-10 is an instrument that has shown good psychometric properties and is practical for use on a session-by-session basis with people presenting with psychological distress in mental health settings. Its Spanish version will be used. In Ecuador, this version has shown good psychometric properties. CORE-10 is administered to adult clients.

The YP-CORE is a brief self-report instrument capable of detecting psychological distress in adolescents, generated by a wide range of problems, while providing information about the person's general functioning. It has 10 items, which must be answered on a 5-point scale (0 to 4). Its Spanish version will be used. The YP-CORE was translated into Spanish and showed adequate psychometric properties. In the present study, we will use a version of this measure, adapted for Ecuador and Latin America, which has good psychometric properties in Ecuador. YP-CORE is administered to adolescents.

The EPO-1 is a single-item outcome measure in which clients assess their current emotional and psychological state by responding to the question: "At this moment, how are you doing emotionally and psychologically?" This item is scored on a 5-point scale ranging from 0 ("Very bad; I can barely handle things") to 4 ("Very well; I have no significant complaints"). EPO-1 is administered to all clients.

The CRES-4 scale has 4 items: one question on satisfaction, one on the level of resolution of the main problem, one on emotional state before the start of treatment, and one on emotional state when completing the questionnaire. These questions allow interpretations of the perceived change in their emotional state, satisfaction, and problem resolution. In this study, the Spanish version of this measure will be used.CRES-4 is administered to all clients.

The CORE-A-TAF is a pragmatic form intended to be completed by therapists at baseline. The CORE-TAF includes referral information, sociodemographic data on the client, and data on the nature, severity, and duration of the client's problems. We will use its Spanish version, which is currently being translated and adapted for use by the CLIP.

The CORE-A-EoT is a pragmatic form designed to be filled out by therapists immediately after treatment completion. The CORE-A-EoT reports on the completed treatment, including the number of sessions, type of therapy, length and frequency of sessions, whether the ending was planned or unplanned, and the potential benefits of therapy. We will use its Spanish version, which is currently being translated and adapted for use by the CLIP.

The PST-Q is a 20-item self-report instrument with a 7-point Likert scale (1 "Completely Disagree" to 7 "Completely Agree"). It assesses the therapist's position across five dimensions: instructional, expressive, involvement, attentional, and operative. Therapists will complete the PST-Q.

This form is intended to be completed by the supervisors or authorities of each service. It collects general data about the center, such as the type of population it serves, its annual average number of users, etc. Supervisors will complete this form.
