Key result
PERMA-based positive psychology linked to better glycemic control, lower distress, and improved self-management in T2DM.
Why the study?
To explore the effect of a PERMA model-based positive psychological intervention on psychological distress and compliance behavior in patients with type 2 diabetes mellitus.

Does a PERMA model-based positive psychology intervention improve glycemic control, psychological distress, and self-management behaviors in patients with type 2 diabetes mellitus?
p-value: p=<0.05
A PERMA model-based positive psychology intervention added to standard care improves glycemic control, psychological distress, and self-management in patients with type 2 diabetes.
May support adjunctive PERMA interventions in T2DM; leaves open confirmation in randomized trials before practice change.
Objective To explore the effect of positive psychological intervention of the PERMA model on psychological distress and compliance behavior in patients with type 2 diabetes mellitus (T2DM). Methods This study used convenience sampling to enroll 120 patients with type 2 diabetes (T2DM) who were admitted between January and December 2023. Participants were assigned to one of two non-equivalent groups based on their treatment pathways in clinical practice: the intervention group ( n = 60) that received positive psychology interventions based on the PERMA model in addition to standard care, and the control group ( n = 60) that received standard care only. After a three-month follow-up period, glycemic control indicators (including Glycosylated Hemoglobin (HbA1c), fasting blood glucose, and 2-h postprandial blood glucose), diabetes-related psychological distress scores, and self-management behavior scale scores were compared between the two cohorts. Result Compared to the control group, the intervention group demonstrated significantly greater improvements in HbA1c (7.16 ± 0.59), fasting blood glucose (5.53 ± 0.72), and 2-h postprandial blood glucose (8.26 ± 0.94) (all p < 0.05). Additionally, the intervention group showed significantly lower scores for diabetes-related psychological distress and significantly higher scores across all dimensions of self-management behaviors (all p < 0.05). Conclusion The PERMA model-based positive psychology intervention effectively alleviates psychological distress, enhances self-management capabilities, and improves glycemic control in patients with T2DM. It represents a valuable adjunctive approach to standard diabetes care.

Zeng et al. (2026) conducted an observational in type 2 diabetes mellitus (n=120). PERMA model-based positive psychology intervention vs. standard care was evaluated on Glycemic control indicators, diabetes-related psychological distress scores, and self-management behavior scale scores (p=<0.05). A PERMA model-based positive psychology intervention significantly improved glycemic control, psychological distress, and self-management behaviors compared to standard care in T2DM (all p<0.05).
