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.

Do Childhood Callous-Unemotional Traits Drive Change in Parenting Practices?

This study examined the relationship between callous-unemotional (CU) traits and parenting practices over time in a mixed-sex community cohort (N = 1,008; 52.6% boys), aged 3 to 10 years (M = 6.5, SD = 1.3). Measures of CU traits, externalizing psychopathology, parenting practices, and socioeconomic risk factors were collected at baseline, and parenting practices and CU traits were reassessed at 12-month follow-up. CU traits uniquely accounted for change in three domains of parenting (inconsistent discipline, punishment, and parental involvement). Likewise, multiple domains of parenting (positive parenting, parental involvement, and poor monitoring/supervision) uniquely predicted change in CU traits. These seemingly bidirectional dynamics between CU traits and parenting were found to be largely moderated by child age and sex. Results partially replicate previous findings regarding the association between quality of parenting and prospective change in CU traits, and provide initial evidence that CU traits disrupt parenting practices over time.

The Nature and Extent of Non-Suicidal Self-Injury in a Non-Clinical Sample of Young Adults

This study aimed to examine the nature, extent and correlates of non-suicidal self injury (NSSI) in a non-clinical sample of young adults. Two hundred and eleven participants (18–30 years) completed self-report questionnaires assessing history of NSSI, emotional regulation, coping strategies, symptoms of psychopathology, and alcohol use. Of the sample, 43.6% reported engaging in NSSI; approximately 10% engaged in moderate/severe NSSI. Those that reported NSSI reported greater psychopathology, avoidant coping and alcohol use than those who did not self-injure. The extent of these differences was magnified as the severity of NSSI increased. These findings highlight the need to consider any form of NSSI, no matter how mild, as an indication of distress and ineffective coping.

The relationship between coping strategies, alcohol expectancies, drinking motives and drinking behaviour

Numerous models have been proposed in an attempt to explain both alcohol use and alcohol abuse. Many of these models propose that drinking behaviour is the result of a complex interplay of cognitive and behavioural variables including coping strategies, alcohol expectancies and motives for drinking. However few studies have explored how these elements may work together to predict drinking. The current study proposed a mediational model of alcohol use in which coping strategies are related to alcohol expectancies, which in turn are related to drinking motives. Drinking motives were then viewed as proximal predictors of drinking behaviour. There were 454 participants (55.78% female) who completed self-report questionnaires assessing the above constructs. Approximately half the participants completed the questionnaires online, while the others completed the paper and pencil versions of the same measures. Findings generally supported the hypothesised model. The relationship between avoidant coping and drinking behaviour was mediated by alcohol expectancies of increased confidence and tension reduction, which in turn were related to drinking motives. As expected, drinking motives were positively related to drinking behaviour. Negative expectancies were also directly related to drinking behaviour. The results are discussed in light of cognitive models of drinking, and implications for prevention and early intervention of alcohol-use problems.

Child Maltreatment, Subsequent Non-Suicidal Self-Injury and the Mediating Roles of Dissociation, Alexithymia and Self-Blame.

OBJECTIVE Although child maltreatment is associated with later non-suicidal self-injury (NSSI), the mechanism through which it might lead to NSSI is not well understood. The current retrospective case-control study examined associations between child maltreatment and later NSSI, and investigated the mediating roles of dissociation, alexithymia, and self-blame. METHODS Participants were 11,423 Australian adults (response rate 38.5%), randomly selected from the Australian Electronic White Pages, aged between 18 and 100 (M=52.11, SD=16.89), 62.2% female. Data were collected via telephone interviewing. Main outcome measures were reported history of child maltreatment (sexual abuse, physical abuse, neglect) and reported 12-month NSSI. Dissociation, alexithymia, and self-blame were examined as potential mediating variables in the relationship between child maltreatment and later NSSI. All analyses were conducted using logistic regression and adjusted for age and psychiatric diagnosis. RESULTS Results differed by gender. Compared to no child maltreatment, physical abuse (OR 2.75, 95% CI 1.68-4.51) and neglect (OR 2.56, 95% CI 1.65-3.99) independently increased the odds of NSSI among females. Physical abuse (OR 2.69, 95% CI 1.44-5.03) increased the odds of NSSI among males. Sexual abuse did not independently increase the odds of NSSI for males or females. For females, self-blame had the greatest effect on the child maltreatment-NSSI relationship (OR decreased by 14.6%, p<.000), although dissociation and alexithymia also partially mediated the relationship. For males, dissociation had the greatest effect (OR decreased by 12.9%, p=.003) with self-blame also having a relatively strong effect. CONCLUSIONS The results indicate that child maltreatment, and in particular, physical abuse, is strongly associated with the development of subsequent NSSI and may be partially mediated by dissociation, alexithymia, and self-blame for females and dissociation and self-blame for males. Altering attributional style (through cognitive therapy or emotion focussed therapy) and improving the capacity to regulate emotions (through dialectical behaviour therapy) may contribute to reduction or cessation of NSSI.

Drinking motives, drinking restraint and drinking behaviour among young adults.

Motives to drink alcohol are widely thought to be the proximal cognitive factors involved in the decision to consume alcohol beverages. However it has also been argued that the ability to restrain drinking may be a more proximal predictor of drinking behaviour. The current study aimed to examine the relationships between drinking motives, drinking restraint and both alcohol consumption and alcohol-related problems in a sample of young adults. A sample of 221 young adults (aged 17-34 years) completed self-report measures assessing drinking behaviour, motives for drinking and drinking restraint. Multiple regression analyses revealed that coping, enhancement and social motives were related to alcohol consumption and alcohol-related problems, while Cognitive and Emotional Preoccupation with drinking was related to all criterion variables. Further, the relationship between coping motives and drinking behaviour was mediated by preoccupation with drinking. The results are discussed in light of the roles of drinking motives and drinking restraint in risky drinking among young people, and implications for prevention and early intervention are presented.

Emotion Regulation, Coping and Alcohol Use as Moderators in the Relationship Between Non-Suicidal Self-Injury and Psychological Distress

Non-suicidal self-injury is a risk factor for more severe self-injury and later suicide, yet is relatively under-researched in non-clinical populations. In order to prevent more severe self-injury and later suicide, understanding of non-suicidal self-injury is imperative. This study aimed to examine whether coping skills, emotion regulation and alcohol use moderate the relationship between psychological distress and non-suicidal self-injury. Two hundred eighty-nine young adults completed self-report questionnaires assessing the variables of interest. Of the sample, 47.4% reported a history of non-suicidal self-injury. Adaptive coping strategies protected those who were psychologically distressed from severe self-injury. However for those who reported greater distress, this protective effect was negated by heavy alcohol use. Coping skills training may serve to protect young people from self-injury, although those who are severely distressed may also benefit from strategies to limit alcohol use.

Brief report: Emotion regulation and coping as moderators in the relationship between personality and self-injury

Self-injury without conscious suicidal intent is an increasingly prevalent phenomenon particularly among adolescent populations. This pilot study examined the extent and correlates of self-injurious behaviour in a school population sample of 393 adolescents (aged 13-18 years) using a self-report questionnaire. Specifically, we aimed to determine whether personality was related to self-injury and whether this relationship was moderated by emotion regulation or coping strategies. Few personality and coping variables were directly related to self-injury after controlling for age and psychopathology. However the relationship between personality and self-injury was moderated by coping skills and emotion regulation. We suggest future research explore these relationships in order to determine the role of coping skills and emotional regulation training in prevention of self-injury.

Predictors of continuation and cessation of nonsuicidal self-injury

PURPOSE This paper reports the first prospective study of risk factors for continuation of nonsuicidal self-injury (NSSI) during adolescence. METHODS We examined whether NSSI became more severe among those continuing to self-injure 1 year later, as well as characteristics and predictors of continuation, relative to cessation, drawn from a sample of 1,973 community-based adolescents from five states in Australia. Multiple sociodemographic and psychosocial factors were assessed in a series of sequential logistic regressions. RESULTS Of those reporting NSSI at follow-up (12% total sample), 4.1% (95% CI: 3.3%-5.0%; n = 80) continued from baseline and an additional 4.1% had stopped this behavior by follow-up (95% CI: 3.3%-5.1%, n = 81; 3.8% new cases). Frequency, potential lethality and number of methods of NSSI increased among adolescents continuing to self-injure. These individuals also had overall higher frequency and more serious wounds compared with those who had stopped self-injuring, possibly providing parameters to differentiate these groups. Continuation of NSSI was associated with higher frequency (OR = 1.06; 95% CI = .99-1.13, p = .08), lower cognitive reappraisal (OR = .86; 95% CI = .78-.95, p = .004) and higher emotional suppression (OR = 1.10; 95% CI = .98-1.22, p = .09) relative to cessation at T1. CONCLUSIONS These findings may assist to better identify young people more likely to continue self-injuring and also highlight potentially modifiable factors to inform early intervention initiatives.

The role of social drinking motives in the relationship between social norms and alcohol consumption

Social norms are key predictors of college student drinking. Additionally, the social reasons for consumption (i.e. social drinking motives) are important to understanding drinking behaviour. This study investigated the effects of social norms and social motives on alcohol consumption. A total of 229 college students completed an online questionnaire assessing their drinking behaviour, social drinking motives and their perceived drinking social norms. Drinking social norms were assessed as descriptive norms (i.e. the individuals perceived prevalence of alcohol consumption), and injunctive norms (i.e. the individuals perceived approval of drinking by their peers). Additionally, injunctive norms were further separated into distal (socially distant peers) and proximal (socially close peers). Hierarchical regression analyses revealed descriptive norms, proximal injunctive norms and social motives all independently predicted alcohol consumption. Additionally, the relationship between proximal injunctive norms and consumption, and descriptive norms and consumption was mediated by social motives. Lastly, there was a significant three-way interaction between descriptive norms, distal injunctive norms and social motives on drinking. Consideration of both the individual factors and the complex interplay between social norms and social motives on alcohol consumption is necessary to further understand drinking behaviour, and to develop more effective alcohol harm-reduction strategies.
