Prevalence of Nonsuicidal Self‐Injury in Nonclinical Samples: Systematic Review,Meta‐Analysis and Meta‐Regression

Published prevalence estimates of nonsuicidal self‐injury (NSSI) among nonclinical samples are highly heterogeneous, raising concerns about their reliability and hindering attempts to explore the alleged increase in NSSI over time. Accordingly, the objectives of this study were to investigate the influence of methodological factors on heterogeneity in NSSI prevalence estimates, explore changes over time, and estimate overall international NSSI prevalence. Results showed that methodological factors contributed over half (51.6%) of the heterogeneity in prevalence estimates, and, after adjusting for these factors, NSSI prevalence did not increase over time. Overall, pooled NSSI prevalence was 17.2% among adolescents, 13.4% among young adults, and 5.5% among adults. Clearly, development of standardized methodology in NSSI research is crucial if accurate estimates are desired.     

Latina Adolescent Suicide Ideations and Attempts: Associations with Connectedness to Parents,Peers, and Teachers

Associations between suicidal behavior and social‐ecological variables were examined among 1,618 Latina high school students (mean age = 15) from the nationally representative Add Health sample (68% were U.S.‐born). Ideations were associated with having a suicidal friend, lower perceived father support, and overall parental caring. Attempts were associated with having a suicidal friend, and lower perceived teacher and parental support. Peer and mother relationship variables were not predictors of ideations or attempts. The protective role of father and teacher support has not previously been emphasized in the literature. Strengthening connections to parents and teachers may reduce suicidal behavior in adolescent Latinas.     

Suicide Ideations,Suicide Attempts,and Completed Suicide in Persons with Pathological Gambling and Their First‐Degree Relatives

We examined the relationship between suicidal ideations and attempts in 95 probands with pathological gambling (PG), 91 controls, and 1075 first‐degree relatives. The results were analyzed using logistic regression with generalized estimating equations. Thirty‐four PG probands (35.8%) and 4 controls (4.4%) had attempted suicide (OR = 12.12, p < .001); in 13 probands, the attempt occurred before PG onset. Lifetime suicidal ideations occurred in 60 PG probands (63.2%) and 12 controls (13.2%) (OR = 11.29, p < .001). Suicidality in PG probands is a marker of PG severity and is associated with greater psychiatric comorbidity. Offspring of PG probands had significantly higher rates of suicide attempts than control offspring.     

Risk Factors,Warning Signs,and Drivers of Suicide: What Are They,How Do They Differ,and Why Does It Matter?

Research investigating suicide attempts and deaths by suicide has yielded many specific risk factors and warning signs for future suicidal behaviors. Yet, even though these variables are each valuable for suicide prevention efforts, they may be limited in their applicability to clinical practice. The differences among risk factors, warning signs, and “drivers,” which are person‐specific variables that lead individuals to desire death by suicide, are highlighted. The scarce evidence on drivers is described and specific recommendations for conducting future drivers‐focused research and targeting them in clinical practice are suggested.     

Child-related attributions of hostile intent and harsh discipline: Moderating effects of anger

Two studies tested whether attributions of hostile intent (AHI) and anger for ambiguous child behaviors uniquely predict parents’ harsh verbal discipline (HVD) and harsh physical discipline (HPD) or whether AHI only predicts harsh discipline when AHI occurs in conjunction with anger, as suggested by the Integrated Cognitive Model of general aggression (Wilkowski & Robinson, 2010, J. Pers., 78, 9–38). Replicating previous studies, the expected positive bivariate relationships between AHI, anger, HVD, and HPD were found in Study 1 (N = 493). However, when AHI, anger, and the AHI by anger interaction were considered simultaneously, patterns of prediction varied by discipline type. For HVD, high levels of AHI, high levels of anger, and the AHI by anger interaction (at high levels of AHI and anger) each were significant predictors. For HPD, low levels of AHI, high levels of anger, and the AHI by anger interaction (at high levels of AHI and anger) were significant predictors, suggesting a possible suppressor effect for AHI. These results were replicated in Study 2 ( N = 503). Thus, there was support for the contention that AHI only predicts harsh discipline when AHI occurs in conjunction with anger with respect to HPD but this was not the case for HVD. Since AHI suppressor effects were observed for HPD in two large sample studies, variables that may account for the AHI suppressor effects and the need for testing more complex interactive predictive models of harsh parenting behaviors are discussed.
