Psychosis is often a debilitating condition that has a dramatic impact on patients' lives. Medication is an integral part of treatment, but the need for complementary therapies has been recognised. One of these is art therapy, the benefits of which have been recognised by many researchers. However, as a relatively new treatment, especially in Greece, it needs to be further investigated if and how it can claim a place among the available therapies in psychosis. The mixed quasi-experimental pilot study aimed to evaluate the effectiveness of art therapy in patients with psychosis. Nine patients with DSM-5 diagnoses of schizophrenia or other mental disorders (bipolar disorder, major depression, anorexia nervosa, mental retardation, obsessive-compulsive disorder) with psychotic symptoms participated in a 9-month art therapy intervention through 15–24 sessions at the day hospital of Eginition Hospital as part of their treatment plan. Assessments were made at baseline and week 23 of the intervention to evaluate the effect of the intervention on reducing psychiatric symptom intensity, improving interpersonal responsiveness/empathy, and functional performance on weighted scale projects. Quantitative research results showed that the art therapy group improved interpersonal responsiveness/empathy and task performance in psychiatric patients, but had no statistically significant effect on reducing the severity of patients' psychiatric symptoms. Limitations and implications for future research are discussed.

精神病通常是一种使人衰弱的疾病，对患者的生活产生巨大影响。药物治疗是治疗不可或缺的一部分，但人们已经认识到补充疗法的必要性。其中之一是艺术疗法，其好处已被许多研究人员认识到。然而，作为一种相对较新的治疗方法，尤其是在希腊，需要进一步研究它是否以及如何在精神病的可用疗法中占据一席之地。这项混合准实验性试点研究旨在评估艺术治疗对精神病患者的有效性。9 名经 DSM-5 诊断为精神分裂症或其他精神障碍（双相情感障碍、重度抑郁症、神经性厌食症、智力低下、强迫症）并伴有精神病症状的患者参加了为期 9 个月的艺术治疗干预，在中心进行了 15-24 次治疗。 Eginition 医院的日间医院作为其治疗计划的一部分。在干预的基线和第 23 周进行评估，以评估干预对减轻精神症状强度、改善人际反应/同理心以及加权量表项目的功能表现的效果。定量研究结果表明，艺术治疗组改善了精神病患者的人际反应/同理心和任务表现，但对减轻患者精神症状的严重程度没有统计学上的显着效果。讨论了未来研究的局限性和影响。
