Results from Two Countries on How Thwarted Interpersonal Needs Contribute to Understanding Self-Harm.

Self-harming behavior (SHB) represents an important public health issue and is one of the most critical predictors of completed death by suicide. The current study evaluated the incremental contribution of the Interpersonal Theory of Suicide constructs of thwarted belongingness and perceived burdensomeness for the prediction of SHB beyond that associated with having a psychiatric diagnosis. Community adults from two different countries included a Portuguese sample of 414 adults, aged between 18 and 65 years (M = 45.09, SD = 13.11), and predominantly female (79%), and an American sample of 290 adults (198 men, 91 women, 1 unreported) with a mean age of 37.76 years (SD = 10.84) ranging from 20 to 71, who participated online. Results demonstrated mediation effects for perceived burdensomeness in the association of thwarted belongingness with SHB, partial mediation in the Portuguese sample and full mediation in the American sample. Findings also indicated that the interaction between thwarted belongingness and perceived burdensomeness failed to make a statistically significant contribution to the prediction of SHB. The results are discussed within the Interpersonal Theory of Suicide and its relevance for clinical practice.

Dimensionality of Suicide Behaviors: Results within Two Samples from Two Different Countries.

Across two countries and two languages, this research examined the multidimensional associations of suicide behaviors (i.e., life-time attempts, life-time communication of intent to others, life-time self-harming, life-time suicide notes, and current suicide ideation) and empirically relevant psychological risk factors (i.e., different facets of mental pain, perceived burdensomeness, thwarted belongingness, and acquired capability), controlling for depressive symptoms. For the Portuguese sample, two underlying dimensions emerged: an ideation dimension and a behavioral dimension, and for the Canadian sample, three dimensions emerged: an ideation dimension and two behavioral dimensions that can be viewed as a splitting of the Portuguese second dimension. Results highlight possible cultural differences between the two countries and that suicide behaviors should be viewed as a multidimensional phenomenon not as a one-dimensional continuum.

Invalidating childhood environments and nonsuicidal self-injury in university students: Depression and mental pain as potential mediators.

OBJECTIVES: The aim of this study was to evaluate the potential mediating effects of depression and psychache (i.e., extreme mental pain) on the relationship between parental invalidation and nonsuicidal self-injury (NSSI) in young adults. METHOD: A sample of 2474 university students responded to previously validated measures of current NSSI, childhood parental invalidation, depression, and psychache. RESULTS: Using a parallel mediation model, path analysis using structural equation modeling demonstrated full mediation by depression and psychache of the link between parental invalidation and NSSI. CONCLUSIONS: Findings suggest that the association between invalidating childhood environments and NSSI has the potential to be mitigated by addressing issues of depression and psychache.

Psychache Predicts Suicide Attempter Status Change in Students Starting University.

OBJECTIVES: Unlike many investigations that focus on suicide ideation rather than suicidal behavior, the present research evaluates the merit and relative efficacy of psychache (i.e., unbearable mental pain) for predicting self-reported suicide attempts among university students who are starting university. METHOD: A sample of 516 elevated-risk undergraduates was assessed during the first three weeks of starting university and, again, 10 weeks later. RESULTS: Psychache and depression, but not hopelessness, could predict change in suicide attempter status. When measures of psychache, depression, and hopelessness were considered simultaneously, only psychache provided significant, unique predictive power. CONCLUSIONS: Findings are interpreted as supporting Shneidman's model whereby psychache is seen as the cause of suicide.

The multidimensionality of suicide risk factors and criteria in a nonclinical population: Replication across two countries and two languages.

Across two countries and two languages, this research examined the multidimensional associations between suicidality (e.g., past ideation/attempts, communication of intent) and empirically important psychological risk factors (e.g., mental pain, perceived burdensomeness, thwarted belongingness). For samples of 228 Canadian and 331 Portuguese university undergraduates, four dimensions emerged in each sample with two of these, intrapersonal and interpersonal, demonstrating strong replicability across countries and languages. It was concluded that suicidality is a phenomenon that demonstrates some multidimensional similarities across cultures.

Avoidance of psychological pain and suicidal ideation in community samples: Replication across two countries and two languages.

OBJECTIVES: A multidimensional psychological pain model of suicide has been developed that includes three dimensions: affective, cognitive, and avoidance. In the present research, we evaluated the relationships between the three dimensions of psychological pain and suicidal ideation. METHOD: Two community samples from Portugal and the U.S. participated in the research. RESULTS: Hierarchical multiple regression analysis demonstrated that when controlling for the effects of depressive symptoms and psychache, the avoidance dimension, but not the cognitive or affective dimension of psychological pain, explained significant, and unique variance in suicidal ideation in each sample. CONCLUSION: Even when individuals perceive psychological pain, there may not be an elevated risk of suicide, provided that they do not consider suicide as a form of coping to decrease that pain.

A four-year longitudinal study examining psychache and suicide ideation in elevated-risk undergraduates: A test of Shneidman's model of suicidal behavior.

OBJECTIVES: Using a 4-year follow-up design, this research investigated Shneidman's model of psychache (i.e., intense mental pain/anguish) as the cause of suicide. Operationalizing suicidal manifestations using suicide ideation, we evaluated Shneidman's assertion that psychache is the prominent predictor of suicide ideation and that other suicide-related psychological variables associate with suicide ideation only through psychache. METHOD: Eighty-two undergraduates at elevated suicide risk were assessed at baseline and follow-up with measures of suicide ideation and three psychological predictors: depression, hopelessness, and psychache. RESULTS: At baseline, only psychache and neither depression nor hopelessness contributed significant, unique information to statistically predicting suicide ideation. For 4-year change in suicide ideation, only psychache and neither depression nor hopelessness provided significant, unique information. CONCLUSIONS: Results provided partial support for Shneidman's contention of the importance of psychache for suicidal behavior and that other psychological factors are only important to suicide insofar as they relate through psychache.

Response latencies are alive and well for identifying fakers on a self-report personality inventory: A reconsideration of van Hooft and Born (2012).

Van Hooft and Born (Journal of Applied Psychology 97:301-316, 2012) presented data challenging both the correctness of a congruence model of faking on personality test items and the relative merit (i.e., effect size) of response latencies for identifying fakers. We suggest that their analysis of response times was suboptimal, and that it followed neither from a congruence model of faking nor from published protocols on appropriately filtering the noise in personality test item answering times. Using new data and following recommended analytic procedures, we confirmed the relative utility of response times for identifying personality test fakers, and our obtained results, again, reinforce a congruence model of faking.
