“I do want to stop, at least I think I do”: An international comparison of recovery from nonsuicidal self-injury among young people

Phenomenological and cultural understandings of recovery from the perspective of individuals who engage in nonsuicidal self-injury (NSSI) are rare. The primary study objective was to understand similarities across three samples in (a) how young people define recovery from NSSI and (b) what they consider helpful approaches taken by parents and professionals to assist their recovery. […]

Impulsivity and self-harm in adolescence: A systematic review

Research supports an association between impulsivity and self-harm, yet inconsistencies in methodology across studies have complicated understanding of this relationship. This systematic review examines the association between impulsivity and self-harm in community-based adolescents aged 11-25 years and aims to integrate findings according to differing concepts and methods. Electronic searches of EMBASE, MEDLINE, PsychINFO, CINAHL, PubMed […]

Elevated interoceptive deficits in individuals with eating disorders and self-injurious thoughts and behaviors: A replication and extension

Introduction People with eating disorders (EDs) frequently report self-injurious thoughts and behaviors (SITBs). We aimed to replicate and extend findings demonstrating greater interoceptive deficits according to SITB severity. We predicted that interoceptive deficits would be greater among people with versus without lifetime SITBs and among those with multiple suicide attempts compared with single attempts or […]

A comparison of retrospectively reported and ecological momentary assessment-reported perceived social support in predicting ecological momentary assessment-reported non-suicidal self-injury

Introduction: Non-suicidal self-injury (NSSI) urges and behaviors are associated with lower perceived social support and related constructs (e.g., perceived rejection). However, no studies have examined the concordance of retrospective (baseline) and ecological momentary assessment (EMA) perceived social support assessments. Retrospective and EMA reports are often only weakly to moderately correlated; measurement approaches may, therefore, impact observed […]

Covid-19 lockdown and non-suicidal self-injury: A mixed methods analysis of NSSI during Australia’s national lockdown

Objective: The Covid-19 global pandemic has meant large parts of the world’s population have been isolated from others for often months at a time due to lockdown measures to stop the spread. The effects of isolation can be damaging and increase risk of self-injury (NSSI) and suicide. We examined the effects of the first Australian national […]

The relationship between ambivalence over emotional expression and nonsuicidal self-injury among Chinese adolescents: A longitudinal moderated mediation model

Background: Nonsuicidal self-injury (NSSI) has become a significant mental health concern for adolescents. Previous empirical studies have shown that ambivalence over emotional expression is positively associated with negative emotions and behaviors. However, little is known about the relationship between ambivalence over emotional expression and NSSI among adolescents. Therefore, this study used a longitudinal design to examine […]

To identify early risk factors of self-injurious thoughts and behaviours (SITB) among young adults with mental health problems, this case–control study drew data from the Clinical Practice Research Datalink (CPRD), a primary care database covering 8% of the UK population. We explored the role of early […]

Analysis of all non-fatal self-harm cases in an urban area of Japan during pre- and peri-pandemic periods of COVID-19: A population-based study

Background: This study aimed to examine population-based characteristics of non-fatal self-harm in an urban area during pre- and peri-pandemic periods of COVID-19 by sex, age, and severity of self-harm, using pre-hospital medical emergency records. Methods: We used a registry of all pre-hospital medical records of self-harm cases that occurred in Kawasaki City, Japan, between January 2018 and […]

Examining the dynamic relationship between nonsuicidal self-injury and alcohol use experiences

Introduction Nonsuicidal self-injury (NSSI) is a prevalent and concerning behavior and its risk pathways require a greater understanding, particularly in predicting short-term risk. Although the literature has supported a between-person link among NSSI and alcohol use, limited research has directly examined the nuances of this relationship at the within-person level using intensive longitudinal data. Method […]

Influence of nonsuicidal self-injury functions on suicide risk in individuals with eating disorders

Objective Individuals with eating disorders (EDs) display elevated rates of suicidality (i.e., suicidal ideation and behaviors) as well as nonsuicidal self-injury (NSSI) (e.g., self-harm behaviors without intent to die). NSSI—and particularly the functions of NSSI—predict suicidal ideation in general samples; however, to our knowledge, the relation between NSSI functions and suicidal ideation in ED populations […]

Perceived discrimination and suicidal ideation among impoverished and nonimpoverished college students: Different mechanisms via social support, depressive symptoms, and nonsuicidal self-injury

Introduction Being discriminated against is a potential interpersonal factor leading to suicidal ideation. Compared to nonimpoverished students, impoverished students have disadvantages in different aspects, leading to high risks of negative psychological states. However, few studies have contrasted the mechanism of discrimination in suicidal ideation between impoverished and nonimpoverished college students. The present study aimed to […]

Prevalence and correlates of adolescent self-injurious thoughts and behaviors: A population-based study in Burkina Faso

Self-injurious thoughts and behaviors (SITBs) are a growing concern among youth in sub-Saharan Africa, but their prevalence and correlates in this region are poorly understood. We therefore examined self-reported SITBs in a population-representative sample of youth in rural Burkina Faso. We used interviews from 1,538 adolescents aged 12 to 20 years living in 10 villages and […]

Non-suicidal self-injury and suicidal ideation among adolescents: The chain-mediating role of rumination and decentering

Objective: To explore the relationship between non-suicidal self-injury and suicidal ideation in adolescents and examine the roles of rumination and decentering in that relationship. Method: By means of a questionnaire, 175 adolescent patients in a psychiatric hospital in Fujian Province were given the Functional Assessment of Self-Mutilation: Chinese Version, Positive and Negative Suicide Ideation, Ruminative Response Scale: […]

Misclassification of self-directed violence: Does the provision of a definition enhance diagnostic accuracy?

Background: Classification of acts of self-directed violence has been shown to be inadequate in past research. Furthermore, level of expertise have been shown to be unrelated to classification correctness. Aim: The aim of the present study was to investigate whether participants provided with a definition are more reliable in their judgment than participants without a definition. Method: Two hundred sixty-one […]

Psychosocial factors associated with increased adolescent non-suicidal self-injury during the COVID-19 pandemic

Non-suicidal self-injury (NSSI) in adolescents hospitalized with psychiatric disorders continues to increase after the outbreak of COVID-19. This study aimed to explore the relationship between the pandemic and NSSI among adolescents and whether the composition of psychosocial factors related to NSSI has changed during the pandemic. Through the retrospective analysis of medical records retrieved from […]

The association between nonsuicidal self-injury and perfectionism in adolescence: The role of mental disorders

Previous evidence has drawn attention to the fact that maladaptive perfectionism is a risk factor for engagement in nonsuicidal self-injury (NSSI). Until now, few studies have examined this topic, especially among community adolescents. The aim of this study was to explore the relationship between perfectionism dimensions and NSSI functions to examine the potential mediating effect […]

Micro-sequences of anger and shame and non-suicidal self-injury in youth: An ecological momentary assessment study

Objective: Non-suicidal self-injury (NSSI) is a significant mental health concern with the highest prevalence among adolescents. NSSI has been conceptualized as one of the maladaptive strategies to cope with challenging affect or a form of self-punishment. Although characterizing moment-to-moment associations between shame and NSSI in individuals’ real-world environment and partitioning between- and within-person effects is critical […]

Gender differences in the prevalence of nonsuicidal self-injury: A meta-analysis

Epidemiological research on the prevalence of nonsuicidal self-injury (NSSI) has found inconsistent results in terms of gender differences, with some studies showing a higher prevalence for women compared to men and other studies showing no difference. The goal of the current study was to use meta-analytic techniques to better conceptualize the presence and size of […]
