This study aims to evaluate the efficacy of the psychotherapeutic intervention model in nursing on patients with nursing diagnosis of ineffective coping (International Classification of Nursing Practices (ICNP)/North American Nursing Diagnostic Association (NANDA)). For this purpose, first of all, validity and reliability studies of "Coping" and "Self-Esteem", which are the results of NOC (Nursing Outcomes Classification), will be conducted, and then a randomized controlled study will be conducted (Turkish version). 200 patients will be included in the validity and reliability phase of the study, which was conducted in a hospital outpatient psychiatric setting in Turkey. The randomized controlled second phase will be carried out, single-blind, nurse-led, with approximately 20 patients with anxiety randomized to intervention (n=10) or control groups (n=10). The usual treatment and care will be compared with the application of the psychotherapeutic intervention model previously developed in nursing.
