Function and Psychotherapy of Chronic Suicidality in Borderline Personality Disorder: Using the Reinforcement Model of Suicidality

Chronic suicidal ideations: a risk or a protection

Chronic suicidal ideations can be consistently present as part of the individual's sense of identity and self-regulation or as a reoccurring pattern to control intense feelings and communicate and relate experiences or intentions. While they can be the precursor to self-harm and suicide attempts, requiring a thorough risk assessment, they can also represent a way to control, avoid, or contain intolerable feelings and experiences. In addition, suicidal ideations can be either deeply internalized and hidden or indirectly or directly conveyed to others. This article focuses on understanding and approaching chronic suicidal ideations that specifically relate to self- and interpersonal characterological functioning, i.e., sense of identity, self-regulation, emotion regulation, and interpersonal intentions. Suicidal ideations must be identified and assessed both in terms of intention, i.e., motivation, plans, and means to harm oneself or end one's life, as well as in terms of function, i.e., related to selfregulatory strategies for counterbalancing or protecting against overwhelming, painful, and frightening external, interpersonal, or internal experiences. Therapeutic strategies and challenges will be discussed, including engaging patients in the therapeutic alliance and building consistency, trust, and reliability.

Implicit cognitions on self-injurious and suicidal behavior in borderline personality disorder

BACKGROUND AND OBJECTIVES

Performance on implicit measures of suicidality has been associated with suicidal and nonsuicidal self-injury. Despite the high prevalence of self-harm in patients with borderline personality disorder (BPD), no previous study has assessed implicit measures in this patient group.

METHODS

Forty patients with BPD and 25 healthy controls completed three implicit association tests (IATs) (Death words - Me/Others words, Self-Harm pictures - Me/Others, and Self-Harm pictures - Good/Bad words) and a subliminal priming task (effect of the primes "dying"/"growing" on the categorization speed of positive/negative adjectives) as well as measures of psychopathology (suicidal ideation, previous nonsuicidal self-injury, borderline symptomatology, depression, and hopelessness).

RESULTS

Patients with BPD had higher scores on all three IATs than healthy controls. The subliminal priming procedure did not reveal group differences. Correlations between implicit measures and psychopathology among patients with BPD were mostly weak and nonsignificant with a few exceptions: Positive correlations were observed between IAT Self-Harm - Good/Bad and lifetime frequency of nonsuicidal self-injury, between IAT Self-Harm - Me/Others and depression, and between IAT Death - Me/Others and depression. Correlations between implicit measures were weak to moderate.

LIMITATIONS

The study was cross-sectional only, and the study had reduced power as the sample size was limited.

CONCLUSIONS

As expected, patients with BPD had higher scores than healthy controls on the IATs, which indicates higher implicit self-identification with self-harm and death as well as stronger implicit positive attitudes towards self-harm. The mostly weak correlations between implicit and explicit measures speak against the discriminative value of IATs in patients with BPD.

Non-suicidal self-injurious behavior (NSSV) and suicide attempts are well-known features of borderline personality disorder; communicative behavior is poorly studied. Differences between patients with and without NSSV as well as differences in current suicide attempts regarding suicidal communication and NSSV were investigated.In a secondary analysis, data on current and anamnestic NSSV, suicide attempts, suicidal communication, and clinical symptomatology of 87 inpatients were studied.Patients with and without current NSSV did not differ in anamnestic but did differ in current suicide attempts and suicidal communication. In regard to the current inpatient stay, it was observed that patients with and without suicide attempts differed considerably in the variables NSSV (100 vs. 32.5 %) and suicidal communication (71.4 vs. 7.5 %).Current self-injury and suicidal communication are highly significant for risk assessment of current suicidality.

Recurrent suicide attempts affect normalization of HPA axis dysregulation after recovery from major depression

More than 700,000 people worldwide die by suicide every year, and the number of suicide attempts is estimated as 20 times higher, most of them being associated with psychiatric disorders, especially major depression. Knowledge about effective methods for preventing suicide attempts in individuals at high risk for suicide is still scarce. Dysregulation of the neuroendocrine stress response system, i.e., the hypothalamic-pituitary-adrenocortical (HPA) axis, is one of the most consistent neurobiological findings in both major depression and suicidality. While the HPA axis is mostly overactive in depression, individuals with a history of suicide attempts exhibit an attenuated hormonal response to stress. It is unknown, however, whether the HPA axis is constantly attenuated in repeated suicide attempters or whether it regains normal responsivity after recovery from depression. Using the combined dexamethasone suppression/corticotropin-releasing hormone (dex/CRH) test, we assessed HPA axis regulation in acute depression (N = 237) and after recovery with respect to previous suicide attempts. Patients without previous suicide attempts show normalization of the stress hormone response to the second dex/CRH (basal ACTH response and cortisol response) after recovery from acute depression, while patients with multiple previous SA show an increased ACTH response. The change in HPA axis responsivity in patients with only one previous SA lies between the response patterns of the other groups with no change in HPA axis reactivity. Our findings suggest that patients with a history of suicide attempts belong to a subgroup of individuals that exhibit a distinct pattern of stress hormone response during acute depression and after recovery. Future studies may extend our approach by investigating additional psychological stress tasks to gain a broader understanding of the stress pathology of recurrent suicide attempters.

Effects of weariness of life, suicide ideations and suicide attempt on HPA axis regulation in depression

The neuropathological mechanisms leading to suicidality are still unknown, which, in view of an annual toll of around 1 million completed suicides constitutes an urgent clinical and societal problem. Alterations of stress hormone (ACTH and cortisol, representing the activity of the hypothalamic-pituitary-adrenocortical, HPA axis) regulation has been repeatedly studied in context of suicidality. Following a suicide attempt, stress hormone activity seems to be blunted, while depressed patients with suicidal ideation often present with elevated HPA axis activity.

METHODS

We investigated the effects of different forms of suicidality on HPA axis regulation in 568 hospitalized patients of the Munich Antidepressant Response Signature (MARS) project. All patients had a diagnosis of a depressive disorder; 62 patients reported a recent suicide attempt, 192 patients suicide ideation, and 171 patients expressed weariness of life as the weakest form of suicidality, the latter not being analyzed in studies so far. All patients participated in the combined dexamethasone/corticotropin releasing hormone (dex/CRH) test for assessing HPA axis regulation shortly after admission to the hospital.

RESULTS

We found an increased ACTH and cortisol response following the dex/CRH-test in patients that were weary of life. In contrast, stress hormone response in suicide attempters and suicide ideators did not differ from non-suicidal patients. Further, repeated suicide attempts in patients' history were associated with more pronounced stress hormone attenuation.

CONCLUSION

In this so far largest study analyzing the HPA axis with respect to suicidality, we could not confirm the assumption of a general attenuation of HPA axis response in depressed suicide ideators and attempters. Conversely, HPA axis appears to be influenced by divergent effects of a specific suicidal psychopathology as well as outlasting effects of previous suicide attempts. We discuss these findings in the light of recent concepts of suicidality, pointing to multifactorial effects of acute and predisposing conditions on HPA axis reactivity in depressed patients.
