Abstract

Objective: To explore the effect of a positive psychology intervention based on the PERMA model on depressive mood and the quality of life of patients with Parkinson's disease (PD).

Methods: A total of 60 patients with PD with depression hospitalised between February 2022 and February 2023 were selected using a convenience sampling method. They were divided into a study group (30 cases) and control group (30 cases) using the random number table method. The control group was given routine nursing, whereas the observation group was treated using the PERMA model of positive psychological intervention. The Unified Parkinson's Disease Rating Scale (UPDRS), Parkinson's Disease Quality-of-Life Questionnaire (PDQ-39), Hamilton Depression Scale (HAMD), Hamilton Anxiety Scale (HAMA), Positive and Negative Affect Schedule (PANAS), and Connor-Davidson Resilience Scale (CD-RISC) scores were collected and compared before and after the intervention, and patient care satisfaction after the intervention was also recorded and compared.

Results: Statistically significant differences were identified in the UPDRS (t = 4.221, p < 0.001), PDQ-39 (t = 5.331, p < 0.001), HAMD (t = 4.298, p < 0.001), HAMA (t = 3.412, p < 0.001), CD-RISC (t = 3.426, p < 0.001), and PANAS (t = 3.432, t = 4.523, p < 0.001) scores. The UPDRS, PDQ-39, HAMD, HAMA, and negative emotion scores in the study group were lower than those in the control group, whereas the CD-RISC and positive emotion scores in the study group were higher than those in the control group. A significant difference in nursing satisfaction was also determined between the two groups (Z = -2.700, p = 0.012), and this result was higher in the study group (93.33 %) than in the control group (73.33 %).

Conclusion: A positive psychology intervention using the PERMA model can effectively counter the negative psychological states of depression, anxiety, and negative emotion in patients with PD, thereby significantly improving their quality of life, psychological resilience levels, and patient satisfaction.
