Many studies have reported that suicides tend to occur on Mondays. However, owing to a lack of controls, conclusive findings on the potential effects of a day of the week on suicides have been lacking. We analyzed public data for causes of death from 1997 to 2015 in the Republic of Korea. Accidental death was used as a control group. The probability of suicide on each day of the week according to age group was calculated. A total of 377,204 deaths (188,601 suicides and 188,603 accidental deaths) were used. The frequency of suicide was highest on Monday and decreased throughout the week until Saturday...

Adolescence is a critical developmental period marked by an increase in risk behaviors, including nonsuicidal self-injury (NSSI). Heightened reward-related brain activation and relatively limited recruitment of prefrontal regions contribute to the initiation of risky behaviors in adolescence. However, neural reward processing has not been examined among adolescents who are at risk for future engagement for NSSI specifically, but who have yet to actually engage in this behavior. In the current fMRI study (N = 71), we hypothesized that altered reward processing would be associated with adolescents' thoughts of NSSI...

Predictive models that utilize data from electronic healthcare records (EHR) have been developed, investigated, and appear to provide an important resource for suicide prevention in medical settings. Actuarial approaches to predicting suicide may be particularly important given the relative inability of clinicians to accurately predict suicide. Although research regarding predictive models that utilize EHR is certainly promising, ethical considerations for the use of these models to trigger suicide prevention interventions warrant careful consideration...

Research suggests the prevalence of suicide ideation and suicide attempts in the transgender veteran community may be upwards of 20 times higher than nontransgender veterans, who are known to be at increased risk than the general US population. This study aimed to understand the potential influence of external and internal minority stress experienced during and after military service on past-year and recent suicide ideation in a sample of 201 transgender veterans. Nonparametric bootstrapping analyses indicated past-year transgender-specific discrimination and rejection (external minority stress) indirectly predicted frequency of both past-year and past 2-week suicide ideation through past-year shame related to gender identity (internal minority stress)...

We aimed to investigate whether negative social comparisons are associated with key components of the integrated motivational-volitional (IMV) model of suicidal behavior. Specifically, we investigated the relationship between negative social comparisons, suicide ideation, defeat, entrapment, socially prescribed perfectionism, and resilience. Adult participants (N = 422) completed an online survey comprised of a range of psychological measures. An initial regression analysis indicated that negative social comparisons were associated with suicide ideation...

It remains unclear whether the Interpersonal Psychological Theory of Suicide (IPTS; Joiner, ) is generalizable to the population or holds more explanatory power for certain subgroups compared to others. The aim of this study was to (1) identify subgroups of individuals who endorsed suicide ideation in the past month based on a range of mental health and demographic variables, (2) compare levels of the IPTS constructs within these subgroups, and (3) test the IPTS predictions for suicide ideation and suicide attempt for each group...

Using a military sample comprised largely of National Guard personnel, zero-inflation negative binomial regression was applied to estimate the effects of indirect, nonface valid indicators of suicide ideation [Thwarted Belongingness (TB), Perceived Burdensomeness (PB), and Hopelessness], in predicting suicide ideation. Data from a sample of 497 military personnel (82.1% male; mage  = 27.24; range = 18-59) were analyzed. TB and the interaction of TB with Hopelessness were significant predictors in the logistic regression, and in the negative binomial regression, the main effects of TB and hopelessness, and the interactions of TB with hopelessness and PB with hopelessness were significant...

We examined hopelessness as a predictor of suicide ideation in depressed youth after acute medication treatment. A total of 158 depressed adolescents were administered the Children's Depression Rating Scale-Revised (CDRS-R) and Columbia Suicide Severity Rating Scale (C-SSRS) as part of a larger battery at baseline and at weekly visits across 6 weeks of acute fluoxetine treatment. The Beck Hopelessness Scale (BHS) was administered at baseline and week 6. A negative binomial regression model via a generalized estimating equation analysis of repeated measures was used to estimate suicide ideation over the 6 weeks of acute treatment from baseline measure of hopelessness...

The aims of this study were to analyze whether positive and negative affect, social support, and loneliness are factors longitudinally related to suicide ideation in the general population in different age groups. A total of 2,392 individuals from a nationally representative sample of the Spanish general population were evaluated in 2011-2012 and in 2014-2015. After including relevant control variables in the analyses, lower positive affect was prospectively related to ideation in 18- to 59-year-old individuals, whereas feelings of loneliness were related to ideation in 60-year-and-older individuals...

Family interactions of 71 adolescents hospitalized following a suicide attempt were compared with those of 29 psychiatric controls, using observational methods and a 2-year prospective, longitudinal design. Parent-adolescent dyadic interactions were coded for emotional validation and invalidation, and problem-solving constructiveness. There were no between-group differences for parents. However, adolescents who had attempted suicide displayed more emotional invalidation than controls. Within the suicide attempt group, maternal constructive problem solving predicted greater declines in youth suicide ideation, and a similar trend was observed for fathers...

Evidence for proximal risk factors for suicide is based on case-control psychological autopsy studies, with these reports showing that mood and substance use disorders are the most prevalent mental disorders among suicide decedents worldwide and are associated with marked risk. However, moderators of risk and the degree of risk associated with (nonalcohol) drug use disorder are unknown. A comprehensive search was used to identify 35 case-control psychological autopsy studies published worldwide over a 30-year period that were metaanalyzed using random effects models...

Recent studies have identified anxiety sensitivity (AS) as a risk factor for suicidality; however, limited work has been performed to understand this risk within the context of the interpersonal-psychological theory of suicide (IPTS; Joiner, 2005). The current study examined the relationship between overall AS, each AS subfactor (cognitive, social, and physical), and the three IPTS domains (perceived burdensomeness, thwarted belongingness, and acquired capability). While each AS subfactor uniquely predicted one IPTS domain, greater overall AS only predicted greater acquired capability, suggesting that assessment of AS at the subfactor level may offer us more information about an individual's interpersonal suicide risk...

The cross-cultural generalizability of the interpersonal theory of suicide was examined in this study. One hundred ninety-nine adults in an inpatient setting in Mexico completed the Personal Resources Questionnaire, Beck Hopelessness Scale, Interpersonal Needs Questionnaire, Acquired Capability for Suicide Scale, and Suicide Behaviors Questionnaire-Revised. Analyses revealed the interaction between perceived burdensomeness and thwarted belongingness did not predict suicide ideation. The interactions between perceived burdensomeness and thwarted belongingness and between perceived burdensomeness and acquired capacity significantly predicted suicidal behaviors, whereas the hypothesized three-way interaction did not...

Differences and similarities were studied in the functions of two different self-injurious behaviors (SIB): nonsuicidal self-injury (NSSI) and sex as self-injury (SASI). Based on type of SIB reported, adolescents were classified in one of three groups: NSSI only (n = 910), SASI only (n = 41), and both NSSI and SASI (n = 76). There was support for functional equivalence in the two forms of SIB, with automatic functions being most commonly endorsed in all three groups. There were also functional differences, with adolescents in the SASI only group reporting more social influence functions than those with NSSI only...

Suicide prevention is a major health care responsibility in need of new perspectives. This study reviews Zero Suicide, an emerging approach to suicide prevention that embraces the aspirational goal of zero suicides among patients treated in health care systems or organizations. Zero Suicide is gaining international momentum while at the same time evoking objections and concerns. Fundamental to Zero Suicide is a multilevel system view on suicide prevention, with three core elements: a direct approach to suicidal behaviors; continual improvement of the quality and safety of care processes; and an organizational commitment to the aspirational goal of zero suicides...

Although childhood abuse is a well-known risk factor for suicide, no studies have investigated the role of interpersonal-psychological (Joiner, 2005), constructs in this association. This study examined whether childhood physical, sexual, and emotional abuse were associated with IPTS constructs, and whether depressive symptoms mediated these associations. Ninety-one participants completed self-report measures. Emotional abuse predicted perceived burdensomeness and thwarted belongingness, and depressive symptoms mediated these associations...

Despite high rates of suicide ideation (SI) and behavior in youth with pediatric bipolar disorder (PBD), little work has examined how psychosocial interventions impact suicidality among this high-risk group. The current study examined SI outcomes in a randomized clinical trial comparing Child- and Family-Focused Cognitive Behavioral Therapy (CFF-CBT) for PBD versus psychotherapy treatment-as-usual (TAU). Although not designed for suicide prevention, CFF-CBT addresses child and family factors related to suicide risk and thus was hypothesized to generalize to the treatment of suicidality...

Sexual harassment has been associated with suicidal behaviors, and with the rise in suicides in the U.S. military, sexual harassment's role in suicide has been of growing interest. Lacking are studies that examine group- or unit-level variables in the relationship of sexual harassment to suicidal behaviors (thoughts, plans, and attempts). In this study, survey data from soldiers (12,567 soldiers in 180 company-sized units) who completed the Unit Risk Inventory administered during calendar year 2010 were analyzed using hierarchical linear modeling...

In recent years, Mexico has seen one of the largest increases in suicide rates worldwide, especially among adolescents and young adults. This study uses data from the 1,071 respondents who participated in a two-wave longitudinal study when they were between 12 and 17 years of age, and again when they were between 19 and 26 years of age. The World Mental Health Composite International Diagnostic Interview assessed suicidal behavior and DSM-IV mental disorders. We used Cox regressions to evaluate which sociodemographic and psychiatric factors and life events predicted the incidence and remission of suicide ideation, plan, and attempt throughout the 8-year span...

Assessment of a patient after hospital-treated self-harm or psychiatric hospitalization often includes a risk assessment, resulting in a classification of high risk versus low risk for a future episode of self-harm. Through systematic review and a series of meta-analyses looking at unassisted clinician risk classification (eight studies; N = 22,499), we found pooled estimates for sensitivity 0.31 (95% CI: 0.18-0.50), specificity 0.85 (0.75-0.92), positive predictive value 0.22 (0.21-0.23), and negative predictive value 0...
