Trajectories of Suicide Ideation,Nonsuicidal Self‐Injury,and Suicide Attempts in a Nonclinical Sample of Military Personnel and Veterans

Nonsuicidal self‐injury (NSSI) is a risk factor for suicide attempts, but little is known about NSSI among military personnel and veterans, or about the temporal sequencing of NSSI relative to suicide ideation and attempts. This study evaluates trajectories of suicide ideation, NSSI, and suicide attempts in a sample of 422 military personnel and veterans. Of those with a history of NSSI, 77% also experienced suicide ideation. Suicide ideation emerged before NSSI (67%) more often than the reverse (17%). Of those with a history of suicide attempt, 41% also engaged in NSSI. NSSI emerged prior to the first suicide attempt (91%) more often than the reverse (9%). The length of time from suicide ideation to suicide attempt was longer for those who first engaged in NSSI (median = 3.5 years) compared with those who did not engage in NSSI (median = 0.0 years), Wald χ²(1) = 11.985, p = .002. Age of onset was earlier for participants reporting NSSI only compared with those reporting both NSSI and suicide attempts (16.71 vs. 22.08 years), F(1, 45) = 4.149, p = .048. NSSI may serve as a “stepping stone” from suicide ideation to attempts for 41% of those who attempt suicide.

The results of this study illustrated the primacy of individual differences in the relationship between physiological responses before speech and stuttering severity.     

Suicide Ideation and Attempts among Inhalant Users: Results from the National Epidemiologic Survey on Alcohol and Related Conditions

Few studies have examined associations of inhalant use and inhalant use disorders (IUDs) to suicide ideation and attempts. We investigated these relationships in the largest comorbidity survey conducted in the United States. Suicidal ideation was significantly more prevalent among inhalant users than nonusers and severity of inhalant use problems was positively related to suicidal ideation. Among persons with IUDs, 67.4% had thought about committing suicide and 20.2% had attempted suicide. Multivariate logistic regression analyses indicated that respondents with IUDs reported significantly higher levels of suicide ideation than inhalant nonusers. Inhalant use is associated with significantly increased risk for suicide ideation, especially among women and persons with DSM‐IV IUDs.     

Detecting Suicide Risk Among College Students: A Test of the Predictive Validity of the Modified Emotional Stroop Task

Detecting suicide risk among nonclinical populations is challenging due to low base rates and the help‐negation tendency of at‐risk individuals. The current longitudinal study investigated the predictive validity of the modified emotional Stroop task (EST) by conducting a follow‐up study of 197 students who participated in a study by Chung and Jeglic (2016). The EST latencies for suicide‐related cues and past suicidal behaviors were the only significant predictors of suicide risk. The findings of this study provide preliminary support for the use of the EST as part of a suicide risk screening battery that could add to the detection of suicide risk.     

Comparisons of the Interpersonal–Psychological Theory of Suicide Constructs Among Individuals Without Suicidality,Ideators, Planners,and Attempters

The Interpersonal–Psychological Theory of Suicide (IPTS) proposes that combinations of thwarted belongingness, perceived burdensomeness, and acquired capability lead to suicide ideation, planning, and attempting. We compared individuals with and without suicidality on thwarted belongingness and perceived burdensomeness, and compared a combined group of planners and attempters to ideators on fearlessness about death (one component of acquired capability). Individuals with suicidality had higher thwarted belongingness and perceived burdensomeness than individuals without suicidality. Planners and attempters did not have higher fearlessness about death than ideators. These findings partially support IPTS hypotheses. Assessing thwarted belongingness and perceived burdensomeness may improve suicide risk determination.     

Suicides around Major Public Holidays in South Korea

A dip and peak pattern of suicide around major public holidays has been found in developed countries and explained by the broken promise effect. Focusing on two major holidays in South Korea (New Year's Day and Thanksgiving Day, both on the lunar calendar), replication of the dip and peak pattern was done by analyzing individual information on all suicides from 1997 to 2014. The replicated pattern revealed the most vulnerable group to be married men aged 50+ in nonmetropolitan areas in 2006–2014. Families, friends, and policy makers can use these findings to save the vulnerable.     

Sociodemographic and Clinical Differences Between Suicide Ideators and Attempters: A Study of Mood Disordered Patients 50 Years and Older

Our study sought to characterize mood disordered suicide ideators and attempters 50 years and older admitted to a psychiatric ward either for a recent suicide attempt or for ongoing suicidal ideation. We enrolled 50 patients with suicide ideation consecutively admitted to an inpatient department and 50 patients admitted for a suicide attempt made in the last 48 hours. Suicide attempters more frequently had low social support and an age of onset of mood disorder of 46 years and older, and less frequently had a history of suicidal behaviors in the family members and pharmacological treatment, despite the fact that the groups did not differ with regard to antidepressants prescribed. The groups were not distinguishable based on several variables assumed to be risk factors for suicide behavior, such as proximal life events and stressors or alcohol use disorders. In both samples, comorbidity with organic diseases, the presence of stressful life events in the past 12 months, and a diagnosis of major depression were frequently reported. In conclusion, the presence of low social support and the absence of a pharmacotherapy may increase suicidal behaviors in patients at risk.
