Abstract:
Objective:This study aimed to explore the potential chain mediating role of psychological resilience and perceived social support in the relationship between childhood trauma and suicide risk in patients with bipolar disorder (BD). This study aimed to provide new insights for the intervention and prevention of suicide in BD patients focusing on psychosocial, familial, and social support.Methods:From March 2023 to September 2023, a total of 116 patients who were hospitalized and met the ICD-10 diagnostic criteria for BD at the Fuzhou Neuropsychiatric Hospital of Fujian province were assessed using Suicide Risk Assessment Scale, Childhood Trauma Questionnaire, Perceived Social Support Scale, and Psychological Resilience Scale. SPSS 26.0 was used for statistical analysis.Patients were divided into high and low suicide risk groups based on their scores from the Suicide Risk Assessment Scale. Statistical analysis was performed using SPSS 26.0, employing χ2 tests, t-tests, or Mann-Whitney U tests to compare demographic characteristics, clinical features, and scale scores between the two groups. A mediation model was constructed using Hayes′ Process extension for SPSS to analyze the mediating effects of psychological resilience and perceived social support on the relationship between childhood trauma and suicide risk. Results:(1)Compared with the low suicide risk group, BD patients with high suicide risk had a higher proportion of unmarried status (χ2=6.42, P=0.039), a higher proportion of depressed individuals (χ2=24.69, P<0.001), and a earlier onset age ( Z=-2.06, P=0.036). (2)Compared with the low suicide risk group, BD patients with high suicide risk had higher scores for childhood trauma, different trauma type (emotional neglect, physical neglect, emotional abuse, and physical abuse), but lower scores for perceived social support (family support, friend support, other support), and psychological resilience (toughness, strength, optimism) (all P<0.05).(3) Suicide risk scores of BD patients were significantly correlated with the scores of childhood trauma, perceived social support, and psychological resilience ( r=0.49, -0.44, -0.52, P<0.05), the scores of childhood trauma were significantly correlated with the scores of perceived social support and psychological resilience ( r=-0.57, -0.52, P<0.05). A significant correlation was found between perceived social support and psychological resilience scores ( r=0.70, P<0.05). (4)Psychological resilience and perceived social support played a chain-mediating role in the relationship between childhood trauma and suicide risk in BD patients, with a mediating effect size of 38.94%, and the confidence interval of this mediating effect did not include zero. Conclusions:Psychological resilience and perceived social support act as chain mediators in the relationship between childhood trauma and suicide risk in BD patients. The assessment and intervention targeting factors such as childhood trauma, psychological resilience, perceived social support could be incorporated into the management of suicide risk in BD patients.
