Recent stressful life events and identity development in emerging adults: An examination of within-person effects.

OBJECTIVE: To examine longitudinal associations among stressful life events and identity processess in emerging adults while accounting for within-person and between-person effects. BACKGROUND: Theoretical perspectives suggest that stressful life events may impact one's identity (i.e., coherent sense of self), but few studies have considered how changes in stressful life events are associated with changes within an individual's identity development over time (within-person effects). METHODS:  Recent stressful life events (i.e., academic problems, friendship problems, romantic problems, and time pressure) and the processes through which identity develops (e.g., exploring in breadth and depth) were examined longitudinally (T1-T3) in a sample of emerging adults (N = 1125, Mage = 17.96 years). RESULTS: Random-intercept cross-lagged modeling demonstrated that at the between-person level, emerging adults with greater academic and friendship problems, as well as more time pressures (relative to their counterparts), tended to engage in greater ruminative exploration. Further, those with more academic problems tended to demonstrate weaker commitment-making and exploration in breadth and depth (relative to their counterparts). Within-person increases in romantic problems predicted lower commitment-making and higher ruminative exploration over time. CONCLUSION: Findings suggest that romantic problems may predict within-person changes in identity processes, whereas academic problems, friendship problems, and time pressure may be more concurrently related to identity development.

Longitudinal Associations among Identity Processes and Mental Health in Young Adulthood: The Mediating Role of Social Support.

Emerging adulthood (ages 18-25) is a period of identity exploration, particularly for young adults navigating the transition to post-secondary school. Little is known about how changes in identity exploration may be related to emerging adults' mental health, or the role of social support plays in identity-related processes. In the present study, associations among identity exploration, internalizing symptoms, and perceived social support were examined. Participants included a diverse group of emerging adults (N = 1,125, Mage = 17.96 years) studying at a Canadian university. Random-intercept cross-lagged modeling demonstrated that within-person increases in exploration in breadth predicted fewer depressive symptoms over time, whereas within-person increases in exploration in depth predicted more depressive and anxious symptoms over time. A mediation effect from perceived support from significant other to depressive symptoms via exploration in breadth was also evident. Findings suggest that identity exploratory processes may be developmentally relevant in emerging adulthood, but their implications for mental health may differ. Perceived social support is also meaningfully related to identity exploration and mental health.

A Daily Diary Study of the Relation between Stress and Nonsuicidal Self-Injury and the Moderating Role of Emotion Dysregulation in Emerging Adulthood.

Research on exposure to stressors and nonsuicidal self-injury (NSSI) in daily life has been lacking, particularly among emerging adults (aged 18-25 years). The aim of this study was to determine whether daily stressors predicted same-day and next-day NSSI thoughts and engagement, and whether emotion dysregulation moderated this relation. Participants included 160 emerging adults (83% female, Mage = 19.75, SD = 1.8, 44% White, 22% East Asian, 11% South Asian, and 23% other) who completed a baseline assessment and 14 days of daily diary entries which resulted in 1982 daily assessments (median compliance = 86%; IQR = 12-14). It was found that daily stressors significantly predicted same-day, but not next-day, NSSI thoughts and engagement and this relation was more pronounced for individuals with greater emotion dysregulation. The present study provides new insight into when individuals may be most at risk for NSSI, as well as which individuals may be most vulnerable.

A Person-Centered Investigation Into the Co-Development of Perceived Stress and Internalizing Symptoms Among Post-Secondary Students.

The early post-secondary years are regarded as a period of heightened vulnerability for stress and internalizing symptoms among emerging adults. However, there is a lack of research examining variability in stress and internalizing symptoms among students, the co-occurrence of stress and internalizing symptoms, or predictors of distinct profiles of stress and internalizing symptoms. To address these gaps in the literature, 1125 ethnically diverse first-year students (71% female; Mage = 17.96 years, SD = 0.69; 55% East or South Asian, 21% Caucasian, 24% other ethnicity) were surveyed three times across the first year of university. Latent growth mixture models revealed four distinct profiles (i.e., high distress, moderate increasing distress, low distress, high decreasing distress), in which patterns of perceived stress and internalizing symptoms co-occurred. Higher levels of exposure to stressful life events, identifying as female and/or LGBQ+ were associated with increasing and high distress profiles. The findings underscore variability in distress among students, as well as the strong associations between stressful experiences, perceived stress, and internalizing symptoms.

A longitudinal examination of predictors of nonsuicidal self-injury disclosures among university students.

OBJECTIVE: There is a paucity of longitudinal research on predictors of disclosures of nonsuicidal self-injury (NSSI) among emerging adults. However, understanding the factors that facilitate disclosure is critical, as disclosure may serve as a first step in accessing care. To address this gap, the present study examined predictors of prospective NSSI disclosures in a postsecondary student sample. METHODS: A total of 475 university students with a history of NSSI (Mage = 17.96; 74.9% women) reported on several potential predictors of NSSI disclosure, and their disclosure history at baseline and 4- and 8-month follow-ups. RESULTS: It was found that 22% of students reported disclosing NSSI during the first year of university; students who had previously disclosed, and who reported greater NSSI severity, were more likely to disclose over time. CONCLUSION: Results of the present study suggest that disclosures often occur in the postsecondary context, and students who disclose NSSI may engage in more severe NSSI behaviours.

Impulsivity and nonsuicidal self-injury: A longitudinal examination among emerging adults.

INTRODUCTION: Nonsuicidal self-injury (e.g., self-cutting without lethal intent) is a widely occurring behavior among adolescents and emerging adults. Heightened impulsivity during the adolescent and emerging adult years may contribute to an increased risk for nonsuicidal self-injury onset and engagement during these developmental periods; however, longitudinal research on impulsivity and nonsuicidal self-injury among young persons is lacking. METHOD: To extend previous research, and elucidate the direction of effects between impulsivity and nonsuicidal self-injury, 782 emerging adults (75% female) completed assessments of impulsivity and nonsuicidal self-injury annually for three years. RESULTS: Path analysis revealed a bidirectional relation, such that higher impulsivity predicted greater nonsuicidal self-injury frequency over time, and greater nonsuicidal self-injury frequency predicted higher impulsivity over time, even after taking into account past scores on these variables as well as other participant factors (e.g., age, sex, depressive symptoms, anxiety). Gender did not moderate the pattern of associations. CONCLUSIONS: The present findings indicate that impulsivity may not only lead to nonsuicidal self-injury, but that frequent engagement in nonsuicidal self-injury may undermine regulatory skill development and lead to greater impulsivity over time during the emerging adult years.

Stressful Experiences, Emotion Dysregulation, and Nonsuicidal Self-Injury among University Students.

Developmental theory on nonsuicidal self-injury (NSSI; e.g., self-cutting without lethal intent) underscores that stressful life experiences may lead to heightened risk for NSSI, potentially by undermining individuals' emotion coping capacities. Given that the transition to university is often accompanied by new stressors for emerging adults, it is possible that stressors experienced during the university years may lead to heightened susceptibility for NSSI during this developmental period. Cross-sectional research supports a positive association between stressful experiences and NSSI among students; however, longitudinal research is needed to examine the direction of effects and explore potential mediating factors (i.e., emotion dysregulation). In the present study, university students (N = 1132; 70.5% female; mage = 19.11) reported on their stressful experiences in university, difficulties in emotion regulation, and NSSI each year for three consecutive years. Path analysis revealed a bidirectional association between stressful experiences and NSSI. Increased stressful experiences predicted increased risk for NSSI through emotion dysregulation, and NSSI predicted increased stressful experiences through emotion dysregulation. Overall, these findings provide new insight into the processes through which NSSI may be initiated and maintained, as well as elucidate the impacts of NSSI on emotion regulation and stressful life experiences in university.

An Examination of Correlates for Adolescent Engagement in Nonsuicidal Self-Injury, Suicidal Self-Injury, and Substance Use.

Little research has examined potential risk factors for direct versus indirect self-injury among adolescents. To address this limitation, 541 clinically referred adolescents were assessed using the interRAI Child and Youth Mental Health Assessment. Logistic regression analyses revealed that older females who experienced heightened depressive symptoms and neighborhood violence were at increased risk for direct self-injury, specifically nonsuicidal and suicidal self-injury. Additionally, adolescents who experienced higher levels of caregiver distress were at greater risk of suicidal self-injury. In contrast, older adolescents who experienced heightened aggressive behavior were at increased risk for one form of indirect self-injury, substance use. Findings suggest that nonsuicidal self-injury, suicidal self-injury, and substance use are associated with differential risk factors. Implications for targeted prevention strategies are discussed.

The Child and Youth Mental Health Assessment (ChYMH): An examination of the psychometric properties of an integrated assessment developed for clinically referred children and youth.

BACKGROUND: The Child and Youth Mental Health (ChYMH) assessment system was developed by interRAI (i.e., an international collective of researchers and clinicians from over thirty countries) in response to the unprecedented need for a coordinated approach to delivery of children's mental health care. Many interRAI instruments are used across Canada and internationally, but the ChYMH represents the first assessment specifically for children and youth. In the present paper, a short overview of the development process of the ChYMH is provided, and then the psychometric properties of several embedded scales on the ChYMH are examined. METHODS: Participants included 1297 children and youth and their families who completed the ChYMH after being referred to mental health agencies within Ontario, Canada. In addition, smaller subsets of participants (N = 48-53) completed additional criterion measures, including the Social Skills Improvement System (SSIS), the Child and Adolescent Functional Assessment Scale (CAFAS), the Child Behavior Checklist (CBCL), and the Brief Child and Family Phone Interview (BCFPI). RESULTS: Results demonstrated that the ChYMH subscales had strong internal-consistency (Cronbach's higher than .70), and correlated well with the criterion measures. CONCLUSIONS: Findings support the clinical utility of the ChYMH for use among clinically referred children and youth. Implications for children's mental health assessment and practice are discussed.

Nonsuicidal self-injury and affect regulation: recent findings from experimental and ecological momentary assessment studies and future directions.

CONTEXT: Although research indicates that nonsuicidal self-injury (NSSI) may be used as a form of emotion regulation, studies have largely relied on the use of retrospective self-report data, which limits inferences about directionality of effects. Recently, researchers have started to employ lab-based experimental (e.g., guided imagery, acute pain) and moment sampling approaches to the study of NSSI. METHODS: In the present study, we conducted a review of this recent literature, using several electronic databases (e.g., PsychINFO, ERIC, CINAHL). RESULTS: We identified 18 studies that met our inclusion criteria. Findings indicated that the administration of pain was associated with decreases in negative affect among both self-injurers and noninjurers, although these declines were more pronounced for self-injurers in some studies. CONCLUSIONS: We discuss findings within the context of two central theories (i.e., opponent-process theory and distraction theory) and offer several recommendations for future research in this area.

A longitudinal person-centered examination of nonsuicidal self-injury among university students.

Little is known about the development and maintenance of nonsuicidal self-injury (NSSI) over time; however, identifying individuals at risk for NSSI onset or its recurrent engagement is of critical importance for developing effective prevention and intervention strategies. To address this important gap in the literature, we used a person-centered approach to study patterns of change among self-injurers (i.e., new beginners, recovered injurers, relapsers, desisters, and persistent injurers). Undergraduate students (N = 666, 71.1 % female, M age = 19.15) from a mid-sized Canadian university participated in the two-wave study (assessments were 1 year apart). Participants completed the Inventory of Statements about Self-Injury (ISAS, Klonsky and Glenn in J Psychopathol Behav Assess 31:215-219, 2009) at Time 1, and a measure of past year NSSI frequency 1 year later. Participants also completed several measures of psychosocial risk (e.g., problem behaviors, problems with parents) at both time points. Consistent with Nock's (Ann Rev Clin Psychol 6:339-363, 2010) model on the development of NSSI over time, individuals who continued to engage in NSSI across the university years (i.e., persistent injurers) reported greater levels of psychosocial risk as compared to those in the other groups. Moreover, a discriminant function analysis revealed that new beginners, relapsed injurers, and persistent injurers were differentiated from recovered injurers and desisters by increases over time in problem behaviors, problems with parents, internalizing behaviors, and suicidal ideation. Our findings provide new insight into the course of NSSI engagement across the university years, and offer clinicians ways to discriminate among individuals with varying longitudinal patterns of NSSI (i.e., on measures of psychosocial risk, and motivations to stop self-injuring).

Pain tolerance as a 'barrier' to nonsuicidal self-injury: A longitudinal study.

Theoretical perspectives underscore that low pain tolerance may be a relevant 'barrier' to non-suicidal self-injury (NSSI). However, there is limited longitudinal work on the link between pain tolerance and NSSI, which is needed to assess if pain tolerance precedes NSSI engagement, and/or if NSSI precedes altered pain tolerance. Further, assessing both NSSI frequency and versatility (or number of NSSI methods), in addition to engagement, can provide a more nuanced understanding of the influence of pain on NSSI severity. In the present study, 1125 undergraduate students at a large university (72 % female, Mage = 17.96) reported on their NSSI frequency, NSSI versatility, and perceived pain tolerance. Four individual regressions were run to examine the potential bidirectional nature of the association between NSSI frequency and pain tolerance, and NSSI versatility and pain tolerance. Pain tolerance predicted both NSSI frequency and versatility over time. Neither NSSI frequency nor versatility predicted pain tolerance. Results suggest that high pain tolerance may be a risk factor for severe NSSI engagement.

An examination of nonsuicidal self-injury disclosures in a high-risk university sample.

Objective: There is a lack of research examining factors that promote the disclosure of nonsuicidal self-injury (NSSI) among post-secondary students. However, elucidating which factors facilitate disclosures among students - particularly students with high risk NSSI - is important given that disclosure may facilitate access to care. Methods: Participants included 149 post-secondary students with recent NSSI (81% women, Mage = 19.96) who reported on their disclosures, as well as several potential correlates of disclosure. Results: Eighty-seven percent of respondents had disclosed NSSI, often to several informal sources. Students with higher willingness to disclose personally distressing information, perceived levels of social support, stressful experiences, and frequency of NSSI engagement were more likely to disclose NSSI to more types of sources and more unique individuals. Conclusion: Results suggest that disclosure is an ongoing process rather than a single event, and underscore the importance of teaching effective NSSI disclosure responses to campus community members.

A Longitudinal Examination of Recent Posttraumatic Stress Symptoms and Nonsuicidal Self-Injury among University Students.

Nonsuicidal self-injury is a burgeoning mental health concern amongst post-secondary students. In the present study, the link between posttraumatic stress symptoms (PTSS) and nonsuicidal self-injury (NSSI) was examined among post-secondary students over time, while accounting for the role of co-occurring depressive symptoms. Participants were 841 first-year university students with self-reported lifetime histories of trauma who reported on traumatic experiences, PTSS, depressive symptoms, and NSSI at three time points over the course of their first year of university. This study also included exploratory correlational analyses of the relation among PTSS and motivations for NSSI engagement. As expected, PTSS predicted NSSI engagement among students within and across time, though effects were small. The strongest correlations were among PTSS and engaging in NSSI for the purposes of fulfilling self-punishment desires and anti-dissociation (e.g., to reduce feelings of numbness). This study provides further support for theories underscoring NSSI as a means of coping with intra- and interpersonal distress among post-secondary students experiencing stressful life events, such as trauma.

Surprise and delight: Response to informal versus formal mindfulness among university students with self-injury.

Nonsuicidal self-injury (NSSI) is defined as the deliberate destruction of one's bodily tissue without suicidal intent. Mindfulness practice is commonly incorporated into universities' stress management programming and may benefit students with a history of NSSI. However, recent findings suggest that these students may respond differentially to specific types of mindfulness practice (i.e., formal vs. informal practice). The present study qualitatively explored the acceptability of different types of mindfulness practice among university students with a history of NSSI. University students with a recent history of NSSI (n = 36) completed a semistructured interview following a brief mindfulness practice (i.e., either a formal body scan, formal sitting meditation, or informal practice). Reflexive thematic analysis of interview transcripts revealed five key themes. First, there appeared to be general misconceptions regarding what constitutes mindfulness practice (Theme 1). Nevertheless, within the present study, all mindfulness practices were carried out with relative ease (Theme 2). Notably, favorable physical and psychological experiences were predominant in response to informal practice (Theme 3). Preferences regarding level of guidance were more mixed in response to formal versus informal practice (Theme 4). Finally, only informal practice inspired feelings of delight and surprise following practice (Theme 5). Informal mindfulness practice is deemed highly acceptable by university students with a history of NSSI and clinicians should strongly consider emphasizing it in mindfulness-based interventions offered to these students, to provide them with the best opportunity to build a regular mindfulness practice and develop their emotion regulation abilities.

Educational stakeholders' attitudes and knowledge about nonsuicidal self-injury among university students: A cross-national study.

Nonsuicidal self-injury (NSSI) is a commonly occurring, yet historically poorly understood, mental health concern among post-secondary students. The present study sought to identify the current knowledge needs of university stakeholders to inform training efforts around effective NSSI response and student support on university campuses.Participants were 1,762 university students, staff, and student-staff (77% female) from seven universities in Canada, the USA, New Zealand, and Australia.Participants completed an online survey about their attitudes and knowledge of both general mental health and NSSI.University stakeholders reported significantly greater stigma toward NSSI than mental illness in general. Student-staff reported greater perceived knowledge and comfort, and demonstrated greater knowledge of NSSI, than students and staff.Findings underscore the need for additional training and resources to reduce stigma and increase knowledge about NSSI on university campuses internationally.

The effectiveness and acceptability of formal versus informal mindfulness among university students with and without recent nonsuicidal self-injury: Protocol for an online, parallel-group, randomized controlled trial.

BACKGROUND: Mindfulness-based programming comprising both formal (FM) and informal (IM) mindfulness practice is increasingly offered to university students. However, difficulties with emotion regulation, self-criticism, and a potentially complex relationship with their body may undermine the benefits of FM for students with a history of nonsuicidal self-injury (NSSI), given its requirement of sustained attention on thoughts, emotions, and bodily sensations. IM may be better tolerated by these students. This protocol describes a randomized controlled trial comparing a brief FM practice, a brief IM practice, and an active control task in university students with and without recent NSSI. METHODS: Recruitment began in November 2022. An online, parallel-group, single-blind, randomized controlled trial will compare a 10-min, single-session FM practice, a 10-min, single session IM practice, and a 10-min, single session active control task in university students with and without recent NSSI. Outcomes will be assessed immediately pre-intervention and within five minutes post-intervention. The primary outcome will be state mindfulness. Secondary outcomes will be state stress, state well-being, and acceptability. Students with a history of NSSI are expected to report (i) greater improvements in state mindfulness, stress, and well-being, and (ii) greater acceptability in the IM condition, relative to the FM and control conditions. This distinction is not expected to occur in the no-NSSI comparison group. CONCLUSION: This trial is the first to parse out the impacts of FM versus IM practice among university students with and without a history of self-injury. Findings will be relevant to academic and clinical audiences within university settings.

Depressive Symptoms, Perceived Stress, Self-Compassion and Nonsuicidal Self-Injury Among Emerging Adults: An Examination of the Between and Within-Person Associations Over Time.

Many emerging adults report experiencing mental health challenges (e.g., depressive symptoms and perceived stress) during the transition to university. These mental health challenges often coincide with increased engagement in nonsuicidal self-injury (NSSI; e.g., self-cutting or burning without lethal intent), but longitudinal research exploring the nature of the associations among depressive symptoms, perceived stress, and NSSI are lacking. In the present study, it was examined whether depressive symptoms and perceived stress predicted increased risk for NSSI over time (or the reverse), and whether these effects were mediated or moderated by self-compassion. The sample consisted of 1,125 university students (Mage = 17.96 years, 74% female), who completed an online survey three times in first year university. A random intercept cross-lagged panel model revealed that higher depressive symptoms, perceived stress, NSSI, and lower self-compassion often co-occurred, but only NSSI predicted increased perceived stress over time. Theoretical and practical implications are discussed.

Pain analgesia or desensitization? A longitudinal lab-based study on the link between pain and nonsuicidal self-injury.

Mounting evidence suggests that individuals who engage in nonsuicidal self-injury (NSSI) have lower pain sensitivity (e.g., pain thresholds and tolerances) than individuals without a history of NSSI. However, research has been largely cross-sectional, so it is unclear whether low pain sensitivity may increase risk for NSSI, or whether NSSI diminishes pain sensitivity over time. In the present study, the relations among NSSI frequency, versatility (number of NSSI methods), pain threshold, and pain tolerance were examined using a longitudinal research design. Participants included 156 undergraduate students at a large university (87% female; Mage = 19.79) with a recent history of NSSI. Participants reported on their NSSI engagement and completed a cold pressor task in a baseline session, as well as at one year follow-up. Eight regression models were run to examine the nature of the association between the two pain measures (i.e., pain threshold and tolerance) and the two NSSI measures (i.e., frequency and versatility). Pain tolerance and pain threshold predicted NSSI versatility over time, but NSSI frequency and versatility did not predict pain threshold or tolerance over time. Results suggest that low pain sensitivity may be a risk factor for severe NSSI engagement.

A Qualitative Investigation of the Positive and Negative Impacts of the COVID-19 Pandemic on Post-Secondary Students' Mental Health and Well-Being.

Evidence suggests that post-secondary students without pre-existing mental health concerns may have experienced worsening mental health during the COVID-19 pandemic, relative to students with pre-existing mental health concerns. To clarify the psychological impacts of the pandemic, and elucidate why differences may exist among students, 20 interviews were conducted with emerging adults enrolled in university. Using directed content analysis, eight themes were identified: three more common among students with pre-existing mental health concerns, three more common among students without pre-existing mental health concerns, and two shared. Although all students experienced novel stressors during the pandemic, students without pre-existing mental health concerns reported greater increases in social and academic isolation, relative to students with pre-existing mental health concerns. Students with pre-existing mental health concerns also leveraged existing coping repertoires, which further supported their ability to manage pandemic-related challenges. Findings highlight how postsecondary institutions can bolster student well-being.
