Purpose: The evidence on ethnic variation in self-harm risk is growing. This systematic review is the first to synthesise the global epidemiological evidence on absolute and relative rates of self-harm in individuals from ethnic minority backgrounds (including migrant and Indigenous populations). Methods: We identified empirical evidence through database searches (Medline, Embase, and PsycINFO published between 01/01/2000-19/12/2023). Studies were included if they reported absolute and/or relative rates of non-fatal self-harm in general population samples from ethnic minority groups. Lifetime self-harm was excluded. Due to limitations in the available data by country, we present a narrative synthesis and forest plots of the rates only. Synthesis was further stratified by sex, migration status, and self-harm method (where possible). Quality assessment was conducted using modified Newcastle Ottawa Scales. PROSPERO: CRD42021248646. Results: We included 36 studies from 14 countries. Seven (19%) were of reasonable quality. Most were conducted in North America (15/36; 42%) and/or in high-income countries (33/36; 92%). Self-harm risk was elevated amongst certain Indigenous and migrant groups, though there was not always statistical evidence of elevated rates compared to the majority population. High heterogeneity was present. Conclusion: The available evidence was of low quality and heterogeneous, indicating a need for improved reporting of self-harm by ethnicity and nuanced understanding of intersecting factors such as place of birth and migratory status. Appropriate surveillance, particularly in South America and Africa, is required to better understand international variations in self-harm prevalence for ethnic minority groups and inform population health suicide prevention.

Ecological momentary assessment (EMA) captures real-time data on thoughts, emotions, and behaviours within individuals’ natural environments. Although EMA has been increasingly used to examine self-harm, existing reviews have not focused specifically on adolescents. This systematic review examines EMA research on adolescent self-harm, focusing on methodological considerations and key risk and protective factors for self-harm. Five databases, plus pre-print, unpublished and grey literature sources, were searched up to 30 January 2024. Studies were included if published in English, used EMA methodology, included adolescents aged 10–24 years and measured suicidal ideation, suicidal behaviours, or self-harm. The review included 79 studies, published from 2009 to the present. Self-harm was associated with numerous risk factors, including negative affect, stress, interpersonal influences and sleep. EMA was generally well-accepted by adolescent participants, with high compliance rates. The findings highlight the value of EMA in capturing real-time fluctuations in self-harm and associated risk factors among adolescents. EMA demonstrates strong potential for improving understanding and prediction of self-harm; yet challenges remain, including variability in study designs and a lack of clear reporting of the methodologies. Future research should focus on standardising methodologies, increasing participant diversity, and exploring the clinical utility of EMA in early intervention and prevention strategies.

Background: Hate-motivated behaviour (HMB) is a growing public health issue. These behaviours can range from hate crimes to microaggressions and have been associated with wide-ranging consequences. Aims: The current study aimed to explore the relationship between specific adverse childhood experiences (ACEs) and HMB perpetration. Methods: Participants ( n = 447) completed an online cross-sectional survey assessing demographic factors, ACEs and HMB perpetration. Results: Individuals who experienced ACEs were more likely to report engaging in HMB than those who did not experience negative life events during childhood. Abuse, neglect and living with a family member with substance abuse and/or mental health issues were all associated with HMB perpetration. Conclusions: This study provides a more nuanced understanding of the link between experiences during childhood and HMB later in life, by highlighting that specific ACEs were more strongly associated with engaging in these behaviours. Future research should seek to replicate these findings and examine the mechanisms underpinning these relationships.

Hate-motivated behavior (HMB) ranges from microaggressions to criminal acts and is a public health concern with consequences for the physical and mental well-being of individuals, families, and communities. The Hate-Motivated Behavior Checklist (HMBC) was developed with the goal of advancing the measurement of HMB perpetration. To provide insights into perpetration and victimization across the HMB continuum in Scotland, the present study sought to examine the factor structure of both the original HMBC and our adapted victimization version in a sample of adults currently living in Scotland. It also aimed to test associations between HMB and cognitions, which are related to self-directed violence (defeat and entrapment). Participants ( n = 447) completed an online cross-sectional survey assessing demographic factors, HMB (perpetration and victimization), and perceptions of defeat and entrapment. Confirmatory factor analysis was used to examine the factor structure of the HMBC and the adapted victimization version of this checklist and path analyses were implemented to provide insights into potential links between HMB, defeat, and entrapment. In line with previous work, results provided support for interpreting the HMB Checklist as a single-factor total score. This was also true for the victimization version of the checklist. Results indicated that HMB victimization (but not perpetration) was associated with increased perceptions of defeat and entrapment. These findings suggest that the HMBC (for assessing both perpetration and victimization) represents potentially useful tools for HMB research and supports their applicability outside of an American context. Furthermore, by examining HMB through the lens of a contemporary model of suicidal behavior, our findings also provide insights into potential psychological mechanisms linking interpersonal and self-directed violence. Future research should implement prospective research designs and integrate measures of self-directed violence outcomes alongside HMB, defeat, and entrapment, to further advance understanding of this association.

Background: Hate-motivated behaviour (HMB) ranges from microaggressions to criminal acts and is a public health concern with wide-ranging consequences. Aims: The current study aimed to examine the mental health correlates of HMB perpetration, victimisation and co-occurring victimisation/perpetration. Methods: Participants ( n = 447) completed an online cross-sectional survey assessing demographic factors, HMB (perpetration and victimisation), positive mental wellbeing and symptoms of depression and anxiety. Results: HMB victimisation was associated with lower positive mental wellbeing and increased symptoms of anxiety and depression. However, neither HMB perpetration nor co-occurring perpetration/victimisation were associated with any of the three mental health outcome measures. Conclusion: Experiencing HMB as a victim is linked to increased psychological distress. Additional research, which focuses on sampling populations who are known to be at greater risk for involvement in HMB, is needed to fully understand the impact of the victim-offender overlap on mental health outcomes.

Psychological theories of suicide posit conceptually similar constructs related to the development of suicidal thinking. These constructs often evince high-magnitude interrelationships across studies. Within these theories, defeat, entrapment and hopelessness standout as conceptually and quantitatively similar. Theoretical improvements may be facilitated through clarifying the subscale and item-level similarities among these constructs. Factor analytic and phenomenological work has demonstrated equivocal evidence for a distinction between defeat and entrapment; hopelessness is not typically analyzed together with defeat and entrapment despite evidence of large-magnitude interrelationships. This study explored the interrelationships among the foregoing constructs within a sample of undergraduate students (N = 344) from two universities within the Southeastern United States. Participants, oversampled for lifetime history of suicidal ideation and attempts, completed an online cross-sectional survey assessing defeat, entrapment, hopelessness and SI. Exploratory factor and parallel analyses demonstrated support for a one factor solution when analyzed at subscale level of the three measures as well as when all items of the three measures were analyzed together. Ad hoc exploratory structural equation modeling (ESEM) bifactor results evinced support for the existence of a single, general factor at the item level. Item level communalities and bifactor fit indices suggest that hopelessness may be somewhat distinct from defeat and entrapment. Clinical and theoretical implications are discussed in the context of study limitations.

The urgency to reduce knife carrying has been recognised by police services within Scotland and has been addressed by initiatives such as the sharing of knife seizure images on media outlets. This study sought to explore young peoples’ views on the use of knife seizure images as a deterrent to carrying knives by using comparative individual interviews (N = 20). Three themes were discovered: (1) negative reactions towards images of seized knives, (2) images of knives may encourage rather than deter knife carrying, and (3) reinforcement of existing beliefs, stereotypes and stigma. These findings highlight the limitations of using knife seizure images as a deterrent and the importance of involving young people in developing preventative and non-discriminatory approaches to tackling knife crime.

Chronotype describes a person’s general preference for mornings, evenings, or neither. It is typically conceptualized as a continuous unidimensional spectrum from morningness to eveningness. Eveningness is associated with poorer outcomes across a myriad of physical and mental health outcomes. This preference for later sleep and wake times is associated with increased risk of depression, anxiety, and suicidal ideation in both clinical and community samples. However, the mechanisms underlying the negative consequences of this preference for evenings are not fully understood. Previous research has found that sleep disturbances may act as a mediator of this relationship. The present study aimed to explore the associations between chronotype and affective outcomes in a sample of students. Additionally, it aimed to investigate the potential role of insomnia as a mediator within these relationships. Participants (n = 190) completed an anonymous self-report survey of validated measures online which assessed chronotype, insomnia symptoms, and a range of affective outcomes (defeat, entrapment, suicide risk, stress, and depressive and anxious symptomology). Eveningness was associated with more severe or frequent experiences of these outcomes, with participants that demonstrated a preference for eveningness more likely to report poorer affective functioning and increased psychological distress. Mediation analysis found the relationship between chronotype and these outcome measures was completely or partially mediated by insomnia symptom severity measured by the validated Sleep Condition Indicator insomnia scale. Taken together, these findings add further evidence for the negative consequences of increased eveningness. Additionally, our results show that chronotype and sleep disturbances should be considered when assessing mental well-being. Implementing appropriate sleep-related behavior change or schedule alterations can offer a tool for mitigation or prevention of psychological distress in students that report a preference for later sleep and wake times.

This study examined the extent to which active and passive sexting behaviors are associated with family-, school-, peer-, and romantic-level variables. Young people (N = 3,322; 49.1% female, 48.3% male, 2.6% other) aged 11 to 15 years old (M = 12.84,SD = 0.89) took part, and all attended mainstream secondary schools in Scotland. Participants completed self-report measures of school connectedness, parental love and support, perceived susceptibility to peer- and romantic-pressure (e.g., to display behaviors just to impress others), and their involvement in active and passive sexting. The importance of both school- and family-level factors was evident, though perceived romantic-pressure had the largest effect. However, neither school- nor family-level variables were moderated by either perceived romantic-pressure or perceived peer-pressure. Efforts to reduce sexting or increase its safety should primarily seek to tackle young people’s ability to respond effectively to romantic-pressure. It may also be helpful to develop school connectedness and to help families provide support that is constructive and not intrusive.
