ABSTRACT

ObjectiveTo explore the relationship among the perception of interparental conflict， meaning in life and suicidal ideation in patients with borderline personality disorder. MethodsA total of 90 borderline personality disorder patients who visited the Psychiatry or Psychological Counseling Department of the Fourth People’s Hospital of Linyi from June 2017 to December 2020 were enrolled as study group. All patients met diagnostic criteria of Diagnostic and Statistical Manual of Mental Disorders， fifth edition， （DSM-5）. Meantime， another 90 freshmen， sophomores and juniors from a university were set as control group. All selected individuals were assessed using Children's Perception of Interparental Conflict Scale （CPIC） and Meaning in Life Questionnaire Chinese Version （MLQ-C）， then Self-rating Idea of Suicide Scale （SIOSS） was utilized in study group to evaluate the suicidal ideation. ResultsCompared with control group， study group had significantly higher total score and each dimension score of CPIC （t=-2.863~4.728， P<0.05 or 0.01） and lower total score and each dimension score of MLQ-C （t=-2.981~3.197， P<0.05 or 0.01）. The total score and each dimension score of CPIC in study group were positively correlated with the total score and each dimension score of SIOSS （r=0.513～0.972， P<0.01）， and total score and each dimension score of MLQ-C were negatively correlated with total score and each dimension score of SIOSS （r=-0.594~-0.237， P<0.05 or 0.01）. The conflict properties and threat items in CPIC and presence of meaning in MLQ-C had predictive value for suicidal ideation （P<0.05）， which accounted for 59.0% of the total variance altogether. Meaning in life played a partial mediating role between perception of interparental conflict and suicidal ideation（β=0.124， P<0.01）， accounting for 25.11% of the total effect. ConclusionPerception of interparental conflict and meaning in life are predictors of suicidal ideation in patients with borderline personality disorder， and the perception of interparental conflict may indirectly affect suicidal ideation through meaning in life.
