Hallucinations are a mental disorder in which clients experience sensory perception disorders, resulting in false sensations of sound, taste, touch, sight, or smell. Clients with auditory hallucinations hear voices commanding and calling them to perform activities, consisting of two or more voices commenting on a person's behavior or thoughts. Auditory hallucinations are a stimulus disturbance in which clients hear voices, especially human voices. They typically hear voices discussing their thoughts and ordering them to do something. This study aims to describe the application of free-drawing art therapy in nursing care for patients with sensory perception disorders: auditory hallucinations in the DewaRuci Ward of Dr. Amino Gondohutomo Mental Hospital, Central Java. This case report involves three patients (Mrs. S, Mrs. R, and Mrs. A) who exhibited symptoms of auditory hallucinations. Nursing implementation was carried out over three sessions using a step-by-step approach, including techniques for reprimanding hallucinations, medication education, distraction through drawing and coloring, conversational practice, and encouragement to make drawing a routine. The evaluation results showed a significant decrease in indicators of verbalization, hearing whispers, and hallucinatory behavior. The patient experienced a decrease from the "increased" category at the second meeting to "decreased" on the third day, indicating the effectiveness of the art therapy intervention. In conclusion, art therapy has been proven effective in reducing the intensity and frequency of auditory hallucinations in patients with sensory perception disorders. This intervention can be used as an alternative non-pharmacological therapy in psychiatric nursing practice.
