| Summary: | 碩士 === 輔仁大學 === 臨床心理學系碩士班 === 106 === Background: Suicide remains a prominent issue in today’s society. When individuals with maladaptive schemas experience negative life events, they may gradually develop perceived burdensomeness and thwarted belongingness, thereby leading to suicidal ideation. According to the interpersonal theory of suicide, suicidal ideation is rooted in the interpersonal beliefs of perceived burdensomeness and thwarted belongingness. However, current research does not address how perceived burdensomeness and thwarted belongingness are formed. Also, few research endeavors have explored the psychopathological mechanisms underlying maladaptive schemas and suicidal ideation. Given such, the present study aimed to examine an interpersonal-cognitive integration model of suicide using a Taiwanese sample.
Method:The sample consisted of 403 college students (male=145; female=258) who responded to the background questionnaire and completed Young Schemas Questionnaire (YSQ), Interperonal Needs Questionnaire (INQ), Suicide Ideation Scale (SIS), and Beck Depression Inventory-II (BDI-II). Hierarchical regression and path analysis were used to analyze the relationships among early maladaptive schemas, perceived burdensomeness, thwarted belongingness and suicidal ideation.
Results: Maladaptive schemas (specifically, defectiveness/shame, social isolation/ alienation, vulnerability to harm or illness, failure, and subjugation) were found to predict suicidal ideation via perceived burdensomeness. Addtionally, maladaptive schemas (namely, abandonment/instability and emotional deprivation) were found to predict suicidal ideation via thwarted belongingness. Results yielded full mediation.
Conclusion: The present study examined the interpersonal-cognitive integration model of suicide. The maladaptive schemas are believed to be a relatively stable, distal factor whose development occurs during childhood and persists into adulthood. The interpersonal beliefs appear to be proximal factors that develop close to the time that suicidal ideation develops. These two can influence suicidal ideation concurrently. It means that the formation of suicidal ideation is traceable. Early maladaptive schemas, when combined with negative interpersonal beliefs, are likely to lead to the development of suicidal ideation. The research and applied implications of the present findings are discussed.
