The effect of the PERMA model-based positive psychological intervention on the positive and negative emotions of patients with primary cancer undergoing hepatectomy

OBJECTIVES: To explore the effects of psychological intervention based on the PERMA model on positive and negative emotions in patients with primary liver cancer undergoing hepatectomy. METHODS: This study adopted a non-randomized, quasi-experimental design. Patients were assigned to two groups sequentially based on admission time. Forty-two patients hospitalized from July through October 2024 were allocated to the control group, receiving routine perioperative care. A subsequent 42-patient experimental group was enrolled between November 2024 and February 2025, implementing the positive psychological intervention program based on PERMA model. Standardized psychometric assessments, comprising the Connor-Davidson Resilience Scale (CD-RISC), Index of Well-being (IWB), and Hospital Anxiety and Depression Scale (HADS), were administered at three distinct time points: the day of admission (baseline T0), the fourth intervention session (T1) and 1 day after the end of the intervention (T2), to evaluate the positive mental states and negative emotions of the two groups. Linear mixed-effects models (LMM) were employed to analyze longitudinal data, controlling for key covariates and correcting for multiple comparisons using the False Discovery Rate (FDR) method. RESULTS: 0.001). The PERMA-based intervention consistently demonstrated superior outcomes at both the T1 and T2 assessments. CONCLUSION: This study demonstrated that a PERMA-based positive psychological intervention significantly enhances resilience, improves well-being, and reduces anxiety and depression in post-hepatectomy liver cancer patients.
