Investigation of the Effects of Angling as Supportive Therapy in Schizophrenia Treatment on Serum Parameters, Anxiety, Depression, and Quality of Life

This study aims to evaluate the effects of recreational fishing (angling) as a supportive therapeutic intervention in individuals diagnosed with schizophrenia. Schizophrenia is a chronic psychiatric disorder characterized by disturbances in thinking, perception, emotion, and behavior, often accompanied by negative symptoms such as social withdrawal, anhedonia, and cognitive impairment, which significantly reduce quality of life.

Recreational activities, particularly those involving nature-based engagement, have been shown to support psychological well-being through stress reduction, improved attention, and enhanced mood regulation. Angling is considered a mindfulness-like recreational activity that promotes relaxation, concentration, and emotional regulation, potentially offering benefits for individuals with psychiatric conditions.

In this randomized controlled study, participants with schizophrenia will engage in a structured recreational fishing program in addition to standard care. The effects of the intervention will be evaluated on biochemical serum parameters, anxiety and depression levels, and quality of life outcomes. The study also aims to assess the psychosocial well-being of participants and determine the feasibility of integrating angling as an adjunctive non-pharmacological intervention in schizophrenia care.

The findings are expected to contribute to evidence-based complementary treatment approaches in psychiatric rehabilitation.
