Suicidal Behavior in Patients Diagnosed With Bipolar Disorder: The Roles of Biological and Childhood and Adult Environmental Risk Factors
Suicidal Behavior in Patients Diagnosed With Bipolar Disorder: The Roles of Biological and Childhood and Adult Environmental Risk Factors
The purpose of this study is to learn the environmental and psychological factors that impact suicidality in patients diagnosed with Bipolar Disorder. Additionally, the study aims to identify treatments to reduce the suicidal behavior and improve quality of life through a 6-week group-based intervention program.
Bipolar disorder (BD) is a severe, chronic, and relatively common psychiatric illness associated with significant premature mortality, including death by suicide. Given that suicidal behavior is a major public health problem and BD confers the highest risk of suicide among major mental disorders, it is important for clinical researchers to investigate why individuals with BD are at an increased risk for suicidal thoughts and behaviors. Among those diagnosed with BD, approximately 75% of patients experience suicidal ideation in their lifetime, 30% attempt suicide, and about 20% eventually die by suicide. Research has also demonstrated that suicidal acts in BD patients tend to be more lethal as indicated by a lower ratio of attempted suicide to death than in the general population. Given that BD patients use more dangerous suicide methods and die by suicide at an alarmingly high rate, early identification and appropriate treatment are critical. Thus, the proposed study should provide critical information and inform treatment efforts regarding suicide risk in low income BD patients.
Research has consistently demonstrated that childhood maltreatment, including abuse and neglect, are independently associated with increased risk for suicidal ideation/behavior in a variety of populations, including patients diagnosed with BD. Consequently, inquiring about past childhood abuse and neglect when assessing suicide risk in this vulnerable population is important. Moreover, childhood maltreatment has been shown to contribute to impulsive aggression and adult drug use, both of which have been shown to predict suicidal behavior in BD patients. Castroman and colleagues (2014) demonstrated that impulsive aggression was an intermediate factor linking childhood abuse with the severity of suicidal behavior in a large sample of suicide attempters. Similarly, Roy (2011) found that impulsive aggression was a significant mediator in the association between childhood abuse and suicidal behavior in substance-dependent patients. With regards to substance use, current evidence suggests that among individuals abused in childhood, the risk for drug use and subsequent suicidal behavior is increased. Further, among BD patients in particular, there appears to be significant additive effects of childhood maltreatment and drug abuse on suicide attempts.
The associations among these variables may be best explained by the interpersonal-psychological theory of suicide (IPTS), which provides a conceptual framework for understanding why individuals consider and engage in suicidal behavior. The theory differentiates between the desire for suicide and the capability of engaging in suicide behaviors among suicide attempters. Desire is characterized by two constructs, perceived burdensomeness (i.e., one's death is worth more than one's life to others) and thwarted belongingness (i.e., sense of alienation and disconnection). Suicide attempts and deaths are arguably related to the ability to use lethal means on one's self, and require pain tolerance and a developed sense of fearlessness in the face of death. Specifically, Joiner (2005) posits that the capability to initiate suicidal behavior is acquired via exposure to painful and fear-provoking events (e. g., childhood maltreatment) that habituate individuals to the pain and fear associated with death. Consequently, understanding pathways by which distal factors, such as childhood maltreatment, may influence suicidal capability is crucial. The proposed investigation of potential developmental pathways from childhood maltreatment to suicidal behaviors through the risk factors of impulsive aggression and drug use may elucidate the associations among these variables, and subsequently improve the assessment and treatment of suicidal BD patients. Thus, the proposed investigation will focus on the capability to engage in suicidal behaviors as examining all ITPS constructs is beyond the scope of this study. More specifically, the researchers propose to examine the relationships between these environmental and psychological factors in BP patients.
The purpose of this study is to learn the environmental and psychological factors that impact suicidality in patients with Bipolar Disorder. Additionally, the study aims to identify treatments to reduce the suicidal behavior and improve quality of life through a 6-week group-based intervention program. Groups will include topics such as interpersonal/social rhythm and mindfulness interventions, as well as interventions focused on understanding and changing thoughts to better cope with Bipolar Depression.
