Longitudinal association between adolescent sexual identity and sleep quality: The mediating roles of peer victimization and perceived social support

ObjectiveDespite growing evidence of disparities in sleep quality between sexual minoritized and heterosexual youth, the reasons for these disparities are not well understood. LGBQ+ adolescents often experience challenging peer relationships, which could negatively impact their sleep quality. The current study examined the prospective relationship between sexual minority status and sleep quality over 12months and evaluated whether peer victimization and social support at 6months mediated this relationship among adolescents. MethodsThis study involved a secondary analysis of data from a community sample of 800 adolescents (57.5% female; Mage=14.42years, SD=0.83). Data were collected using web-based surveys over 12months with three time-points: baseline, 6-, and 12-month. ResultsApproximately 19.4% of adolescents self-identified as LGBQ+. Compared to heterosexual adolescents, LGBQ+ adolescents reported poorer global sleep quality, lower perceived social support, greater peer victimization, childhood victimization, and were more likely to be female (all ps < .001). In a longitudinal, parallel mediation analysis adjusting for baseline age, gender, global sleep quality, and childhood victimization, LGBQ+ adolescents reported higher rates of peer victimization (b=0.262 [0.049], p < .001) and less social support (b=−0.385 [0.146], p = .008) at 6months compared with heterosexual peers, predicting poor global sleep quality (b=0.495 [0.191], p = .010 for peer victimization and b=−0.161 [0.068], p = .018 for social support) at 12months. ConclusionThese findings highlight that sexual minority adolescents face increased risks of peer victimization and reduced social support from peers, which contribute to poorer sleep quality. The findings may guide the development of adolescent sleep interventions that also improve social health and relationships.

Relative victimization scale: initial development and retrospective reports of the impact on mental health

BackgroundBullying and victimization have been studied in many contexts and classified as peer victimization in school settings and parental or sibling victimization within family settings. Yet, current research is scarce on whether victimization occurring within family settings is specific to parental or sibling victimization. Thus, the current study aims to develop a scale assessing victimization conducted by relatives and provide support for its psychometric properties.MethodsCross-sectional and longitudinal data were collected from university students (1622 and 1045 students, respectively) and participants responded to questionnaires via an online survey.ResultsEFA and CFA results demonstrated the unidimensionality of the Relative Victimization Scale (RVS) consisting of eight items. In terms of convergent validity, RVS scores were correlated with the scores on parental, sibling, and peer victimization scales and several psychological health outcomes including depression, anxiety, social anxiety, perceived stress, loneliness, negative and positive affect, life satisfaction, and resilience. Moreover, RVS explained a significant amount of variance beyond the contribution of parental, sibling, and peer victimization in those psychological health outcomes for the support of incremental validity.ConclusionsThe findings of the study indicated the potential utility of the RVS in assessing the experience of relative victimization through offering support for internal consistency reliability and construct, longitudinal predictive, and incremental validity.

Population Attributable Fractions of Adolescent Health and Well-being Outcomes Associated with Adverse Childhood Experiences in a Provincially Representative Sample in Ontario, Canada

BackgroundIt is well known that Adverse Childhood Experiences (ACEs) are associated with poor health and well-being outcomes among adult samples. However, there are notable gaps in examining these relationships among youth. ObjectiveThe objectives were to examine: a) the prevalence of an expanded list of ACEs among adolescents, b) ACEs sex differences, c) associations between ACEs and several adolescent health and at-risk behavioural outcomes, and d) the population attributable fractions (PAFs) for three ACE groupings (i.e., child maltreatment, household challenges, and peer victimization). Study DesignCross-sectional. Participants and SettingData were from the provincially-representative, cross-sectional 2014 Ontario Child Health Study (N = 6,537 dwellings, response rate = 50.8%). One randomly selected child aged 14 to 17 years old (n = 2,910) from each household was included. MethodsThe majority of measures (nine ACEs and six health and well-being outcomes) were self-reported (three household challenges ACEs and physical health were collected from parents/caregivers). Descriptive statistics estimated the prevalence of ACEs for the sample and by sex. Logistic regressions tested associations between individual ACEs and seven outcomes. Population attributable fractions (PAFs) were computed for three ACE groupings with each outcome. FindingsACEs prevalence ranged from 1.8% to 47.4% with several noted sex differences. Each ACE was associated with four or more studied outcomes. PAFs ranged from 3.5% to 47.8%, varying for each ACEs grouping. ConclusionThe significant associations and estimated proportions of poor adolescent outcomes attributed to ACEs indicate that identifying approaches aimed at preventing these experiences could have a substantial impact on youth health and well-being.

Gender Nonconformity, Minority Stress, and Psychological Distress Among Sexual Minority Adolescents.

Purpose: Sexual minority adolescents (SMAs) have disproportionate experiences of mental health symptoms during adolescence, and minority stress contributes to mental health inequities among SMAs. Gender nonconformity (GNC) could place SMAs at higher risk for minority stress and subsequent mental health symptoms. The current study was designed to examine associations between GNC, minority stress, and psychological distress among SMAs. Method: SMAs ages 12-17 years (n = 455; mean age = 15.52 years) in the United States completed a cross-sectional online survey from February to July 2022, including measures of GNC, peer victimization, family rejection, negative expectations, negative disclosure experiences, internalized homonegativity, and psychological distress. We conducted path analysis to examine associations between GNC, minority stressors, and psychological distress, including indirect effects of GNC on psychological distress via minority stress. Results: In multivariable path analysis adjusted for demographic characteristics, GNC was associated with higher levels of peer victimization and negative expectations and lower internalized homonegativity among SMAs. Higher levels of peer victimization and negative expectations were associated with higher psychological distress. GNC was indirectly related to higher levels of psychological distress via higher peer victimization. Conclusions: The current study is the first to document associations between GNC and multiple minority stress experiences among SMAs, and GNC was indirectly related to psychological distress among SMAs via peer victimization. Although all SMAs would benefit from interventions designed to reduce peer victimization and increase their capacity to cope with minority stress, such interventions may be particularly beneficial for SMAs who are gender nonconforming.

Common neural correlates of disgust processing in childhood maltreatment and peer victimisation.

Childhood maltreatment and peer victimisation are common sources of early-life interpersonal stress. Childhood maltreatment is associated with atypical frontolimbic emotion processing and regulation, and increased vulnerability for self-harm/suicide. However, few studies have compared the neurofunctional correlates between caregiver- versus peer-inflicted mistreatment. We compared the alterations of neurofunctional correlates of facial emotion processing in youths exposed to childhood maltreatment or peer victimisation, and explored their associations with self-harm. Functional magnetic resonance imaging data were collected from 114 age- and gender-matched youths (39 childhood maltreatment, 37 peer victimisation and 38 controls) during an emotion discrimination task. Region-of-interest (amygdala, insula) and whole-brain analyses were conducted. Groups differed significantly during disgust processing only. Both groups had lower activation in the right amygdala and bilateral posterior insula than controls; left insular underactivation was furthermore related to increased self-harm in maltreated youths. Compared with controls, at the whole-brain level, both groups also had underactivation in a cluster of bilateral limbic-thalamic-striatal, precuneus/posterior cingulate, temporal, fusiform/lingual and cerebellar regions, which was negatively associated with emotional problems in controls, as well as a cluster of somatosensory regions associated with increased self-harm in maltreated youths. Early-life interpersonal stress from caregivers or peers is associated with common underactivation of limbic-thalamic-striatal, precuneus/posterior cingulate and somatosensory regions during disgust processing. The hypoactivation of key emotion and sensory processing and self-referential brain regions could be a potential suppressive mechanism to cope with the aversive emotion; however, it may also entail increased risk of affective psychopathology in seemingly healthy youths.

Different influence paths of peer victimization and cybervictimization on non-suicidal self-injury: a longitudinal moderated mediation model

Different influence paths of peer victimization and cybervictimization on non-suicidal self-injury: a longitudinal moderated mediation model

Examining systemic inflammation as a pathway linking peer victimization to depressive symptoms in adolescence.

Adolescents exposed to victimization are at an increased risk for a variety of adverse mental health outcomes, including depressive symptoms. Yet, the biological pathways underlying these associations remain poorly understood. Focusing on within-person processes, we examined whether low-grade systemic inflammation mediated the longitudinal associations between peer victimization and depressive symptoms in adolescence. 207 adolescents (at baseline Mage = 12.69 years; SD = 0.49; 43.5% female) participated in a multi-wave longitudinal study, with assessments repeated every 6 months over 1.5 years. At each assessment wave, participants self-reported their peer victimization experiences and depressive symptoms. Dried blood spots were collected at each wave using a finger prick procedure to assay a key marker of low-grade systemic inflammation, interkeukin-6 (IL-6). Data were analyzed using random-intercept cross-lagged panel models. The cross-lagged paths from IL-6 to depressive symptoms were significant across all models and waves (β12 = .13; β23 = .12; β34 = .08), indicating that when adolescents' levels of low-grade systemic inflammation were above their person-specific average, they reported increased levels of depressive symptoms in the subsequent months. However, no significant cross-lagged within-person associations emerged between peer victimization and either IL-6 or depressive symptoms. The findings provide no evidence for the hypothesized mediating role of inflammation in the within-person associations between peer victimization and depressive symptoms. Nevertheless, they extend prior research by indicating that elevated levels of low-grade systemic inflammation predict the development of depressive symptoms in adolescence.

A longitudinal study of adolescent pathways differentiating suicide ideation and attempt in early adulthood.

Suicide ideation and attempt are leading risk factors for mortality in young adults. However, the adolescent risk factors distinguishing suicide ideation from attempt in young adults remain unclear. The present study aimed to examine the extent to which within-person stability and change in depressive symptoms, school difficulties, and peer victimization from ages 12 to 17 were differentially associated with later suicide ideation and attempt from ages 20 to 23. The study included 1647 participants from the Quebec Longitudinal Study of Child Development (QLSCD; 52% female). Participants reported on their depressive symptoms, school difficulties, and peer victimization at ages 12, 13, 15, and 17, and on suicide ideation and attempt at ages 20 and 23. Data were collected in the Province of Quebec, Canada, between 2010 and 2021. Results indicated that 11% (N = 121) and 8% (N = 86) reported suicide ideation and attempt, respectively, between ages 20 and 23. A random-intercept cross-lagged panel model showed that within-person increases in depressive symptoms during adolescence were related to both suicide ideation and attempt, whereas within-person increases in school difficulties and peer victimization were for the most part related to suicide attempt only. Within-person stability in depressive symptoms from ages 12 to 17 years were also related to suicide attempt, and not ideation. However, this association was only marginally significant. Findings suggest that experiencing unusual rises in school difficulties and peer victimization during adolescence, as well as depressive symptoms persisting over time, may distinguish young adults who think about suicide from those who attempt suicide.

Sex-specific co-developmental trajectories of childhood victimization among elementary school students: Relations to social behavior

This study aimed to identify sex-specific co-developmental trajectories of multiple forms of childhood victimization: family maltreatment (FM), psychological maltreatment by teachers (PMT), and peer victimization (PV), and their relations to prosocial and delinquent behaviors among elementary school students. A total of 4378 Chinese elementary school students (Mage = 9.93; SD = 0.92; 55.14% boys) participated in assessments on five occasions, using six-month intervals. Parallel process latent class growth model analyses revealed three trajectories for boys: Congruent-low (75.64%), High-PV, Moderate-FM and PMT (14.62%), and Moderate-PV, High-FM and PMT (9.74%). Similarly, girls exhibited three trajectories: Congruent-low (81.11%), Moderate-PMT, High-FM and PV (10.54%), and High-PMT, Moderate-FM and PV (8.35%). The results indicated that boys were more susceptible than girls to three forms of childhood victimization. Furthermore, boys were especially vulnerable to co-occurring FM and PMT. In contrast, girls were more vulnerable to co-occurring FM and PV. Additionally, after experiencing childhood victimization, girls showed a greater hindrance in prosocial behavior development, whereas boys exhibited a more significant increase in delinquent behavior. These findings underscore the importance of considering sex differences in understanding multiple forms of childhood victimization and provide important insights for prevention and intervention efforts.

Bully victimization and self-esteem among students with communication disorders

BackgroundBullying is a universal problem among school-aged adolescents, characterized by recurrent and destructive behavior toward peers. Bullying victimization has a strong impact on self-esteem. Students diagnosed with communication disorders are more likely to experience low self-esteem. The study’s main goal is to detect a correlation between victimization and self-esteem in teenage students diagnosed with communication disorders.MethodsFrom October 2023 to March 2024, we conducted this cross-sectional study in the Kurdistan region of Iraq. The study included 150 teenage students of both genders diagnosed with communication disorders. Rosenberg’s self-esteem scale was used to measure self-esteem, and the multidimensional peer victimization scale was used to measure bullying victimization. We analyzed the data using independent samples t-tests, one-way ANOVA, Pearson correlation coefficients, and simple linear regression analysis.ResultsThis study found that students with communication disorders experience high levels of bullying victimization (M = 18.63) and report low self-esteem (M = 13.56). A significant negative correlation was observed between bullying victimization and self-esteem (r2 = 0.21), indicating that bullying accounts for 21% of the variance in self-esteem. Male students were more likely to experience higher levels of bullying victimization and lower self-esteem compared to female students.ConclusionThe study determined the severe impact of bullying on the self-esteem of adolescent students with communication disorders, particularly among males and those with stuttering. The long-term effects of bullying and potential protective factors that could mitigate its impact on self-esteem require further research.

The Compounding Effects of Negative Life Events and Peer Victimization on Internalizing Symptoms in Middle School

ABSTRACT Middle school is a time of transition associated with increases in peer victimization (PV) and stress that warrant additional attention. Middle school students (N = 256; 54.7% male; M age = 12.24, SD age = .94) completed measures of PV, negative life events (NLEs), anxiety, and depression. Students were assessed across 6 time points to examine if PV and the number of NLEs at baseline (Time 1; T1) had a unique and interactive effect on symptoms of depression and anxiety concurrently and over three school years. Results suggest that T1 PV, T1 NLEs, and their interactions were significantly associated with concurrent depression. Moreover, the association between T1 PV and the trajectory of depression was moderated by T1 NLEs. Associations with anxiety were not as substantial; nonetheless, T1 PV was significantly associated with concurrent anxiety. Findings clarify the cross-sectional and longitudinal association between PV and NLEs on internalizing symptoms in middle school with an emphasis on the substantial risk of depression symptomatology.

Attention-deficit hyperactivity disorder symptoms and bullying victimization from childhood to adolescence - A within-person cross-lagged approach.

Attention-deficit hyperactivity disorder (ADHD) and subclinical symptoms of hyperactivity-impulsivity and inattentiveness coincide with an increased risk of peer victimization. What remains unclear are the developmental dynamics of these associations. In a sample drawn from two Norwegian birth cohorts (n = 872; 49.94 % girls), assessed biennially from age 6 to age 14, reciprocal relations between ADHD symptoms and victimization were examined while controlling for symptoms of anxiety and depression. ADHD symptoms were assessed through clinical interviews with parents, whereas victimization was reported by teachers using questionnaires. Random-intercept cross-lagged panel modeling revealed a consistent reciprocal within-person effect of increased ADHD symptoms on victimization, and vice versa. Analyses of subdimensions of ADHD projected a consistent cross-lagged bidirectional relationship between victimization and inattentiveness symptoms only, whereas no such reciprocity was found for hyperactivity-impulsivity symptoms. Results did not differ by gender. Findings suggest that the social context may constitute a vulnerability factor in the etiology of the inattentive subtype of ADHD, and at the same time, that inattentiveness symptoms pose a risk for becoming victimized.

A systematic literature review on the link between peer victimization and literacy during adolescence

Peer victimization and literacy failure are on the rise. Yet, there is little understanding of their interplay, particularly during adolescence–a period of heightened sensitivity to social–emotional and academic maladjustment. Guided by the Developmental Cascades Framework, this systematic literature review elucidated how peer victimization and literacy are directly and indirectly linked via negative behaviors, sex, and grade. A total of 21 studies were published between 1993 and 2022 that focused on typically developing 5th- to 8th-graders. Sample sizes ranged from 140 to 86,372 participants. Results indicated a bidirectional connection between increased peer victimization and poorer literacy. Preliminary evidence was found in support of an indirect link via internalizing behaviors, externalizing behaviors, and school engagement, but ambiguous support for the effect of sex. Taken together, adolescents who experience peer victimization are likely to struggle in literacy, as well as exhibit negative behaviors that may only serve to exacerbate this connection.

Neighborhood ethnoracial diversity and positive psychotic symptoms among youth at high-risk and healthy comparisons

Neighborhood ethnoracial composition has been associated with schizophrenia, but mechanisms are unclear. This study investigates the moderators and mediators of the association between neighborhood ethnoracial diversity and positive symptoms among youth at clinical high-risk for psychosis (CHR-P) and healthy comparisons (HC). Data were collected as part of The North American Prodrome Longitudinal Study and included 492 youth at CHR-P and 136 HCs. Neighborhood ethnoracial diversity measures the probability that two people chosen at random will be from different ethnoracial groups. Attenuated positive symptoms were derived from the Scale of Prodromal Symptoms. Peer victimization and discriminatory experiences were constructed as latent variables. Using structural equation modeling, this study tested the relationship of these variables and included the following covariates: age, sex, neighborhood poverty, and depressive symptoms. Greater neighborhood ethnoracial diversity was associated with reduced positive symptoms among ethnoracial minorities at CHR-P (β=-3.78; 95 % CI [-6.61, -0.84]). Fewer life events of peer victimization (β=-0.13; 95 % CI [-0.24, -0.03]) leading to perceived ethnoracial discrimination (β=0.56; 95 % CI [0.45, 0.67]) mediated 15.06 % of this association. These findings deepen our understanding of the social determinants of psychosis and may help develop effective interventions to prevent psychosis, especially among ethnoracial minority youth at high risk.

Youth exposure to violence and victimization in a South African community sample

Background: Studies show that youth in low socioeconomic communities suffer significant disturbances in mental and emotional health because of exposure to violence and peer victimisation, manifesting in internalising disorders such as depression, anxiety and traumatic stress.Aim: To examine the relation between risks and exposure to community violence and peer victimisation.Setting: Low socioeconomic communities in Durban, KwaZulu-Natal.Methods: Data were collected via school and home interviews with youth and maternal caregivers using standardised schedules and instruments. These included the Demographics and Questions about Child’s Health schedule, the Family History of Risk Questionnaire, the Child Behaviour Checklist, the Social Experiences Questionnaire and the Survey of Children’s Exposure to Violence. Youth sample comprised 256 participants, with age range from 9 to 18 years, and 65% being female.Results: Sociodemographic risks were significantly associated with lifetime witnessing violence, victimisation and hearing about violence. Low maternal education was associated with overt peer victimisation and cyber-victimisation. Internalising conditions such as worry and oversensitivity, fear and concentration, youth anxiety and maternal anxiety were also significantly associated with violence exposure and peer victimisation.Conclusion: Predisposing risks for exposure to violence and victimisation occur in all domains, suggesting that interventions should target these domains to minimise their impact. Co-occurring experience of violence at the personal, proximal and distal levels perpetuate a cyclical loop of violence, intersecting and influencing each other.Contribution: Risk factors such as anxious attachment, avoidant attachment and anxiety, conceptually often seen as maladaptive outcomes, also serve as predisposing risks for violence exposure.

Peer victimization and learning burnout among adolescents: roles of depression and nature connectedness

ABSTRACT This study investigated how depression mediates and nature connectedness moderates the relationship between peer victimization and learning burnout among Chinese adolescents. The survey of 902 adolescents found that the positive association between peer victimization and learning burnout was mediated by depression. Nature connectedness reduced depression in peer-victimized adolescents. Adolescents with low nature connectedness are more likely to experience learning burnout. However, increased levels of nature connectedness enhanced the effect of peer victimization on learning burnout. This study clarifies the relationships between adolescents’ peer victimization, depression, and learning burnout, as well as the role of nature connectedness in this context.

The role of changes in peer victimization from elementary to high school and autonomic reactivity on adolescent reactive aggression.

The goals of the present study were to investigate links between changes in peer victimization from elementary to high school and adolescent reactive aggression (Goal 1), whether heightened autonomic nervous system (ANS) reactivity to social and nonsocial stress increases risk for adolescent reactive aggression (Goal 2), and whether increased ANS reactivity strengthens the association between changes in victimization and adolescent reactive aggression (Goal 3). Participants included 145 adolescents (Mage = 16; 54% female; 76% European American, 13% African American, 11% Latino American, 7% Asian American, 5% of mixed race or ethnicity; 60% with family incomes of $100,000 or greater). We collected self-report data in elementary (Time 1 [T1]); (Time 2 [T2]); middle (Time 3 [T3]); and high school (Time 4 [T4]) to assess victimization. At T4, we measured self-reported reactive and proactive aggression, and ANS reactivity (preejection period [PEP], respiratory sinus arrhythmia [RSA]) to peer rejection and nonsocial frustration. More positive victimization slope over time (meaning both less decreasing slopes and increasing slopes) predicted greater adolescent reactive, but not proactive aggression (Goal 1). Greater RSA augmentation to peer rejection and more PEP reactivity to nonsocial frustration predicted more reactive, but not proactive aggression (Goal 2). The link between victimization slope and reactive aggression emerged only for adolescents exhibiting RSA augmentation to peer rejection (marginal; Goal 3).

Trajectories of academic performance in sexually abused children and potential correlates

Background: Childhood sexual abuse (CSA) is associated with detrimental consequences in children, including lower academic performance. However, studies have rarely explored the diversity of longitudinal academic profiles among CSA victims. Objectives: The objectives of this study were (1) to identify trajectories of academic performance in CSA victims and (2) to explore potential correlates of these trajectories. Participants and settings: The study involved 738 Canadian children between the ages of 5 and 14 who had experienced CSA and their non-offending parent and their teacher. Methods: At three different assessment times, spaced 6 months apart, the child’s teacher was invited to complete a questionnaire regarding the child’s academic performance. Measures of potential correlates of the trajectories were assessed by teacher (child’s behavior problems), parents (children’s experience of peer victimization) and children (coping strategies). Results: The three-trajectory model was selected as the final model. The High functioning trajectory (42%) included children who exhibited high academic performance at the first assessment but decreased slightly over time. The Low and Increasing trajectory (16%) identified children whose academic results were initially low but improved over time. Finally, the Moderate and Stable trajectory (42%) comprised children with an average academic performance over time. Compared to the other two groups, children in the High functioning trajectory were less likely to report peer victimization and show externalizing and internalizing behavior problems as assessed by caregiver and teacher. They were also younger and living in more socially and economically advantaged backgrounds. Conclusions: These results emphasize the crucial role of available resources in a child’s environment and their protective effect on their academic adaptation.

Date SMART’s Impact on Aggression in System Involved Girls: Does Victimization Moderate Effects?

ABSTRACT Aggression and victimization increase negative outcomes for legal system involved girls. While aggression is often enacted against multiple targets (e.g. peers, dating partners), most interventions only target one violence type (e.g. teen dating violence [TDV]). However, TDV shares risk factors with other violence forms; therefore, TDV-specific interventions may reduce other types of violence (e.g. general aggression). The current study explored the effects of a TDV intervention, Date SMART, on general physical and verbal aggression (i.e. aggression not tied to dating) in legal system involved girls (N = 239, Mage = 15.57) and how victimization history (including sexual abuse) moderated treatment effects compared to a Knowledge Only (KO) group. Hierarchical restricted maximum likelihood linear mixed effect models evaluated differences in aggression from baseline to post-intervention and 3-, 6-, and 9-month follow-ups. Findings indicated that from baseline to post-intervention, verbal and physical aggression initially increased in Date SMART relative to KO, but then decreased at a greater rate in the Date SMART group than the KO group throughout follow-ups. Exploratory analyses indicated that victimization history moderated response to Date SMART and KO. Findings suggest that rates of multiple forms of violence can be reduced by Date SMART but may benefit from tailoring for peer relationships and victimization histories.

A latent profile analysis on adolescents' Non-Suicidal Self-Injury related to intrapersonal and interpersonal factors

Non-suicidal self-injury (NSSI) among adolescents continues to be a significant public health concern worldwide. A recent systematic review and meta-analysis found that the global prevalence of NSSI in adolescents aged 12–18 years was 17.2%, with higher rates reported among females (19.7%) than males (14.8%). This behavior has been linked to several negative outcomes, such as depression, anxiety, substance abuse, and suicidal ideation. The present study aimed to classify adolescents based on intrapersonal and interpersonal factors associated with NSSI proposed in Nock’s (2009) integrated model of NSSI, to identify distinct clusters targeting specific risk factors. This encompassed negative cognition, emotional vulnerability, poor coping skill, peer-victimization, family adaptability, and perceived stress. A total of 881 adolescents aged 11–16 years in South Korea completed self-reported questionnaires on automatic thoughts, depression, emotional regulation, peer victimization, family adaptability and perceived stress. Latent profile analysis (LPA) revealed three distinct classes: “the severe group”, “the moderate group”, “the mild group”. Class 3 (“severe group”: N = 127) exhibited greater severity related to NSSI, including negative cognition, emotional vulnerability, poor coping skills, peer victimization, and perceived stress, with weaker levels of factors that can prevent NSSI compared to class 1 (“mild group”: N = 416) and class 2 (“moderated group”: N = 338). The present study emphasizes the importance of considering both intrapersonal (e.g., negative automatic thoughts & emotional dysregulation) and interpersonal factors (i.e., peer victimization) when understanding NSSI - among adolescents. These findings can be utilized to develop interventions aimed at reducing the prevalence and severity of NSSI among adolescents.
