Background: Current empirical literature demonstrates a paucity of evidence elucidating the intricate network relationships between personality traits, emotion states, self-management behaviors, and quality of life (QOL) in patients with type 2 diabetes mellitus(T2DM). This cross-sectional study aimed to investigate these relationships using structural equation modeling(SEM). Methods: A cohort of 839 T2DM patients was systematically recruited from 69 community health service centers in Hangzhou, China, between 2016 and 2020. Standardized instruments were administered to assess demographic characteristics, personality traits(Chinese Big Five Personality Inventory-15, CBF-PI-15), emotional states( Self-Rating Anxiety Scale [SAS] and Self-Rating Depression Scale [SDS]), self-management behaviors (Type 2 Diabetes Self-Care Scale, 2-DSCS), and QOL(MOS 36-Item Short-Form Health Survey, SF-36). Date analyses were performed using SPSS 26.0 and AMOS 21.0. Results: Descriptive statistics revealed the highest mean score for agreeableness (13.58 ±2.55), whereas self-management subdomains exhibited comparatively lower scores (blood glucose monitoring: 12.17 ± 4.10; regular exercise: 12.35 ±4.89). Significant anxiety and depressive symptoms were present in 20.4% and 28.6% of participants, respectively. Bivariate correlations show significant positive associations between self-management behaviors and both psychological/physiological QOL dimensions, alongside negative correlations with anxiety, depression, and neuroticism. The SEM analysis yielded excellent model fit indices (χ²/df =3.556, AGFI =0.946, GFI =0.967, CFI =0.957, IFI =0.957, RMSEA =0.055), with anxiety emerging as the most robust predictor of QOL (β = -0.542,), followed by depression (β = -0.360) and self-management behaviors (β = 0.342). Mediation analysis confirmed the significant intermediary roles of anxiety and depression in pathway linking self-management behaviors to QOL (indirect effects accounting for 33.70%、30.33% of total variance).Conclusion: These findings elucidate the complex psychobehavioral mechanisms underlying QOL in T2DM patients, highlighting the critical mediating role of emotional states between self-management and QOL. The results underscore the imperative for integrated interventions targeting both emotional regulation and behavioral modification in diabetes care protocols.
