Background

Nonsuicidal self-injury (NSSI), or ‘the deliberate, self-inflicted destruction of body tissue…without suicidal intent and for purposes not culturally sanctioned’, is a robust predictor of future suicide-related behavior and therefore a modifiable target for suicide prevention. The prevalence of NSSI is rising in adolescents, particularly among females; however, it is unknown whether sex differences also exist in the clinical and psychosocial factors associated with NSSI. Understanding how the correlates of NSSI differ by sex is important for developing tailored treatments. This study systematically reviews sex differences in the clinical and psychosocial correlates of NSSI among adolescents.

Methods

MEDLINE and PsycINFO were searched using the keywords ‘adolescents’, ‘self-injury’, and ‘sex factors’ and synonyms for English-language articles published between January 1, 2000 and May 10, 2022. We included studies that presented original data on NSSI, included adolescents ages 10–19, reported sex differences, and explicitly defined self-injury as that done without suicidal intent. Fifty-seven studies containing 54 unique samples were included. Data were summarized by sex and recorded by: (a) characteristics of NSSI, (b) clinical and psychosocial correlates of NSSI, and (c) associations with suicide.

Results

We used data on NSSI from 54 unique samples of adolescents worldwide. Males more commonly used violent methods of NSSI, such as burning, and were more likely to be physically aggressive and experience substance abuse. Females more commonly self-injured by cutting, and their NSSI was more likely to be repetitive and associated with emotional distress. In both sexes, NSSI was associated with adverse childhood experiences (ACEs) such as sexual abuse/violence and bullying. NSSI was predictive of suicide in females but not males.

Conclusions

Data from 22 countries and 352,516 participants suggest important sex differences in the clinical and psychosocial factors associated with NSSI among adolescents that future assessment and treatment strategies ought to consider.

ABSTRACT

Research examining relations between language skills and social competence has yielded mixed findings. Three meta-analyses investigated links between language skills (overall, receptive, and expressive) and social competence in 2- to 12-year-old children. Data from 130 studies representing 62,120 children (M age at language assessment = 4.70 years; 52% male), predominantly from North America and Europe, and identifying as White (33%), Black (17%), Hispanic (14%), Asian (2%), Mixed (4%), Indigenous (1%), and Other/Unspecified (29%) were analyzed. Analyses indicated significant medium-sized associations between social competence and: overall language (r = 0.27), receptive language (r = 0.23), and expressive language (r = 0.20). Exploratory analyses indicated significant moderating effects of study design, publication status, social type, and geographic region. Results and implications are discussed.

Abstract

Empirical findings on the associations of positive and dysfunctional parent–child relationship (PPCR/DPCR) characteristics with child shame, adaptive guilt, and maladaptive guilt were synthesized in six meta-analyses. The 65 included samples yielded 633 effect sizes (N _total = 19,144; M _age = 15.24 years; 59.0% female; 67.7% U.S. samples, n = 12,036 with 65% White, 12.3% Hispanic and Latinx, 10.8% Black, 6.3% mixed race, 5.6% Asian American, 0.3% Native American participants). Small positive correlations were found between DPCR and shame (r = .17), DPCR and maladaptive guilt (r = .15), and PPCR and adaptive guilt (r = .14). A small negative correlation was found between PPCR and shame (r = −.12). Sample and study moderators and sources of bias are investigated and discussed.

Abstract

Abundant research has indicated fluency features as meaningful predictors of second language proficiency. However, the extent to which different fluency dimensions and features can predict proficiency remains underexplored. This meta-analysis employed a multilevel modeling approach to synthesize fluency–proficiency relationships from 71 empirical studies from 1959–2023. Additionally, we examined several moderator variables, including task type, learning context, age, and proficiency measure. The correlations found were strongly positive for speed (r = .55), moderately positive for productivity (r = .38), moderately negative for breakdown (r = −.33), and weakly negative for repair (r = −.11). Moderator analyses revealed that task, learning context, and proficiency measure influence fluency–proficiency relationships in the repair, productivity, and speed dimensions, respectively. Post hoc analyses also suggested that the operationalization of breakdown features might make a difference in fluency–proficiency relationships. This study has both theoretical and methodological implications for second language fluency research.

ABSTRACT

Aims

Research on family functioning in psychosis has typically focused on specific family-related factors and their impact on symptomatology, finding strong associations between high expressed emotion and poor outcomes, especially in those with long-term illness. The objective of this review is to examine the impact of a broad range of family-related factors and their relationship with clinical, social, occupational and relational outcomes in first-episode psychosis (FEP).

Method

A systematic search of databases PsycInfo, Pubmed, Embase and CINHAL between 1990 and August 2023 was completed. In total, 1408 articles were screened, and study quality was assessed using the JBI critical appraisal checklists for analytical cross-sectional studies and cohort studies. A narrative synthesis approach was used to analyse the data.

Results

Of the 1408 identified articles, 80 full-text articles were screened. Fifteen studies were included for data extraction. The objectives and scope of the selected studies varied considerably. Studies consisted of cross-sectional and prospective cohort designs. Participants consisted of FEP patients and family members, with the patient age range varying from 15.9 to 30.8 (MD = 24.5). Significant associations were identified between family factors (high EE, family environment and carer burden) and symptom and social outcomes.

Discussion

While findings emphasised the significant impact of family factors on symptomatic and social outcomes, the literature had significant limitations due to the absence of underlying theoretical models and understanding of the dynamics of distress in families within FEP. Future research should seek to develop a model accounting for such processes.

ABSTRACT

Background

Parents of children with moderate to profound intellectual disabilities play a crucial role in providing direct care but often demonstrate heightened parental stress and reduced quality of life. This review explores perceived quality of life from the experiences of parents when caring for young and adult children.

Method

A qualitative systematic review following Joanna Briggs Institute meta-aggregation approach has been completed and reported according to PRISMA guidelines.

Findings

Seventeen qualitative studies were included. Three synthesised findings were identified: ‘Challenges and rewards of being a parent carer’, ‘The real cost of caregiver burden’ and ‘Surrendering self for duty – the mothers role’.

Conclusion

Parents of children with moderate to profound intellectual disabilities reported diminished quality of life for themselves and their families, experiencing increased physical and mental health issues associated with caregiving burdens. Future research is needed that determine what effective support systems and interventions are needed to alleviate parental caregiver burden.

Psychosis in children and adolescents has been studied on a spectrum from (common) psychotic experiences to (rare) early-onset schizophrenia spectrum disorders. This research review looks at the state-of-the-art for research across the psychosis spectrum, from evidence on psychotic experiences in community and clinical samples of children and adolescents to findings from psychosis risk syndrome research, to evidence on early-onset psychotic disorders. The review also looks at new opportunities to capture psychosis risk in childhood and adolescence, including opportunities for early intervention, identifies important unanswered questions, and points to future directions for prevention research.
