Different self-damaging behaviours, similar motives? Testing measurement invariance of motives for nonsuicidal self-injury, disordered eating and substance misuse.

OBJECTIVES: Theory and research suggest that distinct self-damaging behaviours (SDBs; e.g., nonsuicidal self-injury [NSSI], restrictive eating, binge eating, drug misuse, alcohol misuse) share similar motives. However, few studies have used a common self-report inventory to investigate the shared relevance and relative salience of motives for SDBs. Accordingly, the present study: (1) examined whether self-report scales assessing intrapersonal motives (i.e., relieving negative emotions, enhancing positive emotions, punishing oneself) and interpersonal motives (i.e., bonding with others, conforming with others, communicating distress, communicating strength, reducing demands) have invariant factor structures across SDBs; and (2) compared the salience of these motives across SDBs. METHODS: 1018 adults (54.6% men, Mage = 35.41 years) with a history of SDBs were allocated to the following groups: NSSI (n = 213), restrictive eating (n = 200), binge eating (n = 200), drug misuse (n = 200) or alcohol misuse (n = 205). Participants reported on their motives for engaging in their allocated SDB. Measurement invariance analyses compared the factor structures and latent means of the motive scales across SDBs. RESULTS: The motive scales had comparable factor structures across SDBs. Intrapersonal motives were most strongly endorsed for NSSI and drug misuse. Interpersonal motives were most strongly endorsed for drug and alcohol misuse. All motives were least salient to restrictive eating. CONCLUSIONS: Results suggest that common motives underlie distinct SDBs and that they can be adequately assessed using a single self-report inventory. However, certain motives are more relevant to some SDBs than others, with restrictive eating being the most motivationally distinct SDB. This knowledge can inform transdiagnostic models and interventions for SDBs.

Influence of perceived peer behavior on engagement in self-damaging behaviors during the transition to university.

As students transition to university, they experience significant social changes that can affect their behaviors, including self-damaging behaviors like disordered eating, problematic alcohol/drug use, suicidal thoughts, and non-suicidal self-injury (NSSI). Building on prior work, we examined the associations between (1) perceptions of peers' engagement in self-damaging behaviors predicting one's own subsequent engagement in such behaviors (i.e., socialization) and (2) one's own engagement in self-damaging behaviors predicting perceptions of peers' subsequent engagement in such behaviors (i.e., selection). We also examined whether these associations were moderated by the source of influence (close peer/acquaintance) and degree of social disconnection experienced by the student. First-year university students (N = 704) were asked to complete seven monthly surveys. Multilevel models indicated that when students perceived their close peers had engaged in NSSI or suicidal thinking, they had seven times greater odds of future engagement in the same behavior, implying that socialization increases the risk of these behaviors among university students. Perception of acquaintances' NSSI also predicted greater odds of a student's own NSSI the following month. Social disconnection increased the likelihood of matching own behaviors to perceptions of acquaintances' alcohol abuse, highlighting the importance of fostering connections/mentors to reduce self-damaging behaviors on college campuses. Furthermore, when students engaged in alcohol abuse, they had almost four times greater odds of reporting that their acquaintances abused alcohol the following month, emphasizing the importance of the wider social network in alcohol use behaviors.

Psychometric Properties of the Dutch Version of the Eating Competence Satter Inventory (ecSI 2.0TM) in Community Adolescents.

Eating competence can help adolescents navigate their food choices and attitudes toward eating in a healthy and balanced way. In the present study, we investigated the psychometric properties of the Dutch translation of the Eating Competence Satter Inventory 2.0TM (ecSI 2.0TM), which was developed to assess eating attitudes and behaviors. A sample of 900 Flemish adolescents completed the ecSI 2.0TM DUTCH and two self-report measures on eating disorder symptoms and identity functioning (i.e., confusion and synthesis). Confirmatory factor analysis confirmed the four-factor structure of the ecSI 2.0TM DUTCH, and the resulting four subscales (i.e., Eating Attitudes, Food Acceptance, Internal Regulation, and Contextual Skills) showed acceptable-to-excellent reliability (αs ranging from 0.69 to 0.91). The ecSI 2.0TM DUTCH also demonstrated scalar invariance across sex and age (<17 years, ≥17 years). Males reported significantly higher ecSI 2.0TM DUTCH scores than females on the four subscales and the total scale. The two age groups did not significantly differ on the ecSI 2.0TM DUTCH scales. Finally, scores on the ecSI 2.0TM DUTCH subscales showed non-significant or small negative correlations with adolescents' Body Mass Index (BMI), large negative correlations with eating disorder symptoms and identity confusion, and large positive associations with identity synthesis. The Dutch translation of the ecSI 2.0TM is a valid and reliable instrument to assess eating competence skills in male and female adolescents.

Adherence to and Motivations for Complying With Public Health Measures Among Adolescents During the Coronavirus Disease (COVID-19) Pandemic in Canada.

Background: Public health measures (e.g., minimizing social interactions, social distancing, and mask wearing) have been implemented in Canada to reduce the transmission of COVID-19. Given that adolescents may be a high-risk demographic for spreading COVID-19, this study investigated adherence to and motivations for complying with public health measures among Canadian youth at two points of the COVID-19 pandemic. Methods: Adolescents (N = 1,484, 53% girls, Mage = 15.73 [SD = 1.41]) completed an online survey in either Summer 2020 (Cohort 1 [C1]; n = 809, 56% girls) or Winter 2020/2021 (Cohort 2 [C2]; n = 675, 50% girls). We investigated differences in adherence across cohorts using independent sample t-tests and predictors of adherence using a path analysis. Results: Youth engaged in similar levels of social interaction in C1 and C2. Relative to adolescents in C1, adolescents in C2 reported more mask wearing, but less social distancing. Social responsibility was associated with adherence to almost all public health measures across both cohorts, with one exception: it did not predict minimizing social interactions in C2. Not wanting to get sick predicted minimizing social interactions and mask wearing. Concern with population health predicted adherence to all public health measures in C1 and all but mask wearing in C2. Maintaining social ties was negatively associated with minimizing social interactions in both cohorts, and with social distancing in C1. Conclusions: Youth engaged in more mask wearing but less social distancing as the pandemic progressed. Social responsibility and not wanting to get sick were consistent predictors of adherence to most public health measures throughout the pandemic. Youth shifted away from adhering to mask wearing measures due to concern with population health over the course of the pandemic. These results can inform targeted campaigns to bolster compliance with public health measures among adolescents.

Rapid psychiatric readmission in youth: A five-year retrospective Cohort Study.

This study describes predictors of psychiatric readmission among youth, including rapid readmission within 30 days of discharge. A retrospective chart review identified demographic features, diagnoses, and reasons for initial admission among 1324 youth admitted to the child and adolescent psychiatric emergency unit at a Canadian children's hospital. 22% of youth had at least one readmission and 8.8% had at least one rapid readmission during the five-year period. Personality disorder (HR=1.64, 95% CI=1.07, 2.52) and self-harm concerns (HR=0.65, 95% CI=0.48, 0.89) predicted odds of readmission Reducing readmission is an important goal, particularly for youth with personality concerns.

Examining the components and stability of negative affect in disordered eating frequency.

OBJECTIVE: There is a limited understanding of the unique components of negative affect that are most important to disordered eating. Our study tested the contributions and stabilities of unique components of negative affect in the frequency of both binge eating and restricted eating. We examined if: (1) symptoms of depression, anxiety and stress share unique, concurrent associations with binge eating and restricted eating, respectively, and if (2) instability of depression, anxiety, and stress predict binge eating and restricted eating, respectively. METHOD: 627 first year undergraduate students completed 7 assessments of these constructs across their first academic year. Generalised multilevel modelling was employed. RESULTS: Higher than average anxiety, but not depression or stress, was concurrently associated with restricted eating. No concurrent associations between negative affect and binge eating were found. Instability of depression, but not anxiety or stress, predicted both binge and restricted eating. CONCLUSION: Anxiety may be a more salient predictor of restricted eating than depression or stress. However, larger monthly changes in depression may confer risk for more frequent binge eating and restricted eating.

Between- and Within-Person Correlates of Alcohol-Impaired Driving in First-Year University Students: The Roles of Impulsivity, Binge Drinking, Depression, and Anxiety.

OBJECTIVE: University students are a high-risk demographic for alcohol-impaired driving (AID), a leading contributor to death and injury on Canadian roads. Although between-person correlates of AID are well established, little research has identified within-person correlates that elucidate when AID occurs. Accordingly, this study investigated whether between- and within-person variability in impulsivity, binge drinking, depression, and anxiety are associated with AID in university students. METHOD: Participants were 633 first-year students (75% female, mean age = 17.97 [SD = 0.76]) from a Canadian university who completed seven monthly surveys. Multilevel models disaggregated between- and within-person associations. RESULTS: Between-person elevations in negative and positive urgency, sensation seeking, lack of premeditation, binge drinking, and depression were associated with greater odds of AID. Within-person elevations in negative urgency, sensation seeking, and binge drinking were associated with greater odds of AID, whereas within-person elevations in depression were associated with lower odds of AID. CONCLUSIONS: These results support existing research regarding who is most likely to engage in AID (students with elevated impulsivity, binge drinking, and depression) and extend this research by identifying under what conditions AID is likeliest to occur (when impulsivity and binge drinking are higher than usual, and depression is lower than usual). The opposing between- and within-person associations of depression with AID highlight the need for careful specification of hypotheses, as findings at the between-person level may not generalize to the within-person level. Moving forward, research that elucidates not only for whom but also when AID occurs may be best positioned to inform intervention and prevention efforts among university students.

Testing a diathesis-stress model during the transition to university: Associations between self-criticism, stress, and internalizing problems.

ObjectiveTo test a diathesis-stress model whereby self-criticism interacts with monthly perceived stress to predict same-month or next-month internalizing problems, including depression, anxiety, nonsuicidal self-injury (NSSI), and suicidal ideation, in students transitioning to university. Participants: 704 students (73% female, Mage = 17.97) were recruited during their first month of university in 2017 and 2018. Methods: Students completed surveys assessing self-criticism, perceived stress, and internalizing problems from September to April. Results: Self-criticism predicted higher depression and anxiety, as well as odds of NSSI and suicidal ideation, in students' first month on campus. Consistent with a diathesis-stress model, self-criticism strengthened the associations between stress and same-month depression and anxiety. Conclusions: Self-critical students are at elevated risk of internalizing problems during the transition to university, particularly when they feel more stressed than usual. These findings elucidate which students should be targeted in interventions and when interventions should be delivered to curtail internalizing problems.

Support for a Transdiagnostic Motivational Model of Self-Damaging Behaviors: Comparing the Salience of Motives for Binge Drinking, Disordered Eating, and Nonsuicidal Self-Injury.

Integrating across motivational models suggests that different self-damaging behaviors (SDBs) are enacted for similar reasons. However, it remains unclear whether some motives are more relevant to certain SDBs than others. To answer this question, the present study compared the salience of 8 potentially shared motives across 3 exemplar SDBs, selected to represent different points along the internalizing and externalizing spectra: binge drinking, disordered eating (binge eating, purging, fasting), and nonsuicidal self-injury (NSSI). Seven hundred and four first-year university students (73% female, Mage = 17.97) completed monthly surveys assessing their engagement in and motives for SDBs. Motives were conceptualized as either interpersonal (bonding with others, conforming with others, communicating strength, communicating distress, reducing demands) or intrapersonal (reducing negative emotions, enhancing positive emotions, punishing oneself). Multilevel models compared endorsement of each motive across SDBs. Results revealed that SDBs were motivated by similar goals, albeit to different degrees. Although some exceptions emerged, interpersonal motives were most salient to binge drinking, followed by disordered eating, and then NSSI. In contrast, intrapersonal motives were most salient to NSSI, followed by disordered eating, and then binge drinking. Motivational differences were also found within disordered eating. For example, punishing oneself was more relevant to purging and fasting than binge eating, whereas relieving negative emotions was more relevant to binge eating and purging than fasting. Similar to dimensional models that position SDBs on internalizing or externalizing spectra, the salience of motives for binge drinking and NSSI may fall on distinct spectra (i.e., interpersonal and intrapersonal, respectively), with motives for disordered eating exhibiting elements consistent with both spectra. This study supports a common motivational framework for investigating and potentially treating a variety of topographically distinct SDBs.

Associations between physical activity, affect regulation difficulties, and mental health among Canadian adolescents at two different points of the COVID-19 pandemic.

Objective. Although physical activity declined with social distancing measures and stay-at-home orders during the COVID-19 pandemic, youth who engaged in more physical activity experienced fewer mental health problems. If and how physical activity maintained its protective role throughout the ongoing pandemic remains unclear. This study models associations between three types of physical activity (indoor, outdoor, with parents), affect regulation, and anxious and depressive symptoms in two independent adolescent samples (T1: Summer 2020; T2: Winter 2020/21).Methods and Measures. Six hundred sixty-two Canadian adolescents (T1: Mage = 15.69, SD = 1.36; 52% girls; 5% trans+) and 675 Canadian adolescents (T2: Mage = 15.80, SD = 1.46; 50% girls; 6% trans+) participated in an online survey. Data included frequency of physical activity indoors, outdoors, and with parents, affect regulation difficulties, and measures of anxious and depressive symptoms.Results. Multiple-group path analysis showed indoor physical activity had an indirect effect on anxiety and depressive symptoms through affect dysregulation, but only at T1. Physical activity with parents was protective for adolescent anxiety and depressive symptoms at both T1 and T2 and had an indirect effect through affect dysregulation and suppression.Conclusion. Findings contribute to our understanding of how physical activity protects adolescent mental health, and point to strengthening family supports and recreation opportunities.

Learning from experience: Within- and between-person associations of the consequences, frequency, and versatility of nonsuicidal self-injury.

OBJECTIVE: Behavioral models of nonsuicidal self-injury (NSSI) propose that experiencing desirable consequences following NSSI reinforces the behavior. However, these models do not specify whether experiencing more desirable consequences relative to other people (between-person), an individual's own average (within-person), or both, predicts NSSI severity. To address this gap, this study investigated the prospective, within- and between-person associations of desirable NSSI consequences with NSSI frequency (number of episodes) and versatility (number of methods). METHODS: Two hundred and ten individuals (93.81% female, Mage  = 22.95) with a history of NSSI completed online surveys assessing NSSI consequences, frequency, and versatility every three months for one year. RESULTS: Within-person increases in desirable emotional consequences were unrelated to NSSI frequency three months later but predicted increases in NSSI versatility. Within-person increases in desirable social consequences predicted decreases in NSSI frequency three months later but were unrelated to NSSI versatility. Between-person variability in desirable consequences was unrelated to NSSI severity. CONCLUSIONS: Findings were partially consistent with behavioral models of NSSI. Going forward, we recommend that: (1) behavioral models articulate the salience of within-person fluctuations in consequences; (2) research clarifies the role of social consequences; and (3) clinicians use repeated assessments of emotional consequences to identify periods of elevated NSSI risk.

A Two-Way Street? Reciprocal Associations Between Parental Warmth and Hostility with Substance Use Among Justice-Involved Adolescents.

Transactional developmental theories propose that poor parenting behaviors contribute to youth substance use, and youth substance use contributes to poor parenting behaviors. However, research aimed at testing these theories has not distinguished: (1) between- and within-person sources of variance; (2) maternal and paternal parenting behaviors; and (3) alcohol, marijuana, and other illicit drug use. This study addressed these limitations by investigating the reciprocal associations between maternal and paternal warmth and hostility with alcohol, marijuana, and other illicit drug use among justice-involved adolescents, an at-risk population for substance use. 1354 justice-involved adolescents (86.4% male; Mage = 16.04 [SD = 0.14], range = 14-17; 41.4% Black, 33.5% Hispanic, 20.2% White, 4.8% other race/ethnicity) completed self-reports assessing parental warmth, parental hostility, and substance use every six months for 36 months. Random-intercept structural equation models disaggregated between- and within-person associations. At the between-person level, maternal and paternal warmth were negatively associated with alcohol, marijuana, and other illicit drug use, whereas maternal and paternal hostility were positively associated with alcohol, marijuana, and other illicit drug use. At the within-person level, maternal and paternal warmth predicted decreases in marijuana and other illicit drug use, and paternal warmth predicted decreases in alcohol use six months later. Maternal hostility predicted increases in subsequent marijuana and other illicit drug use. Marijuana and other illicit drug use predicted decreases in subsequent paternal hostility. The results are partially consistent with transactional developmental models proposing recursive influences between parenting behaviors and youth substance use. Evocative effects were in the opposite direction than expected and specific to fathers, such that youth drug use was related to improvements in the father-youth relationship. The results support the potential utility of family-based interventions for substance use among justice-involved adolescents.

Roles of Family Stress, Maltreatment, and Affect Regulation Difficulties on Adolescent Mental Health During COVID-19.

This study examines the indirect effects of affect dysregulation and suppression on the associations between family stress from confinement, maltreatment, and adolescent mental health during COVID-19. We examined both adolescent and caregiver perspectives to yield a more well-rounded understanding of these associations than afforded in previous research. Using both adolescent (N = 809, Mage = 15.66) and caregiver (N = 578) samples, family stress from confinement, exposure to physical and psychological maltreatment, affect dysregulation and suppression, and youth internalizing and externalizing symptoms were measured in the summer of 2020, following three months of stay-at-home orders due to COVID-19. Affect dysregulation partially accounted for the associations between family stress from confinement and psychological maltreatment on both internalizing and externalizing symptoms for youth and caregiver report. Suppression partially accounted for the associations between family stress and maltreatment on internalizing and externalizing symptoms in the youth sample, but only for internalizing symptoms in the caregiver sample. Understanding family predictors of adolescents' mental health concerns and their underlying mechanisms, affect dysregulation and suppression, can inform mental health interventions during and following the COVID-19 pandemic.

Prevalence and Correlates of Suicidal Ideation and Deliberate Self-harm in Canadian Adolescents During the Coronavirus Disease 2019 Pandemic.

OBJECTIVE: In light of recent evidence that the coronavirus disease 2019 (COVID-19) pandemic has resulted in marked increases in depression, anxiety, substance use, and other mental health concerns among Canadian adolescents, we investigated the rates of self-harm thoughts and behaviours in this population. Specifically, this study explored: (1) the demographic and geographic distributions of suicidal ideation (SI) and deliberate self-harm (DSH), and (2) the associations of mental health and substance use with SI and DSH. METHOD: A total of 809 Canadian adolescents, aged 12-18 years, completed an online survey between June 17, 2020 and July 31, 2020. RESULTS: 44% of adolescents reported experiencing SI since the pandemic began, while 32% reported engaging in DSH. SI and DSH were more common among youth who: identified as transgender, non-binary or gender fluid; who did not reside with both parents; and who reported psychiatric concerns or frequent cannabis use. CONCLUSION: Canadian adolescents appear to be experiencing higher rates of self-harm thoughts and behaviours relative to before the COVID-19 pandemic. It is important for adults who are likely to interact with distressed youth to be aware of potential warning signs that a youth is struggling with self-harm, and to refer youth to specialty mental health services where appropriate.

Deliberate self-harm in adolescents during COVID-19: The roles of pandemic-related stress, emotion regulation difficulties, and social distancing.

The objective of this study was to conduct an ecologically valid test of etiological models of deliberate self-harm (DSH) during the COVID-19 pandemic. Using a sample of Canadian adolescents, we investigated: (1) the association between COVID-19-related stress and DSH; (2) whether emotion regulation (ER) difficulties mediated/moderated this association, including whether these effects differed by age; and (3) whether the mediating/moderating effects of ER difficulties were stronger among socially distanced youth. Canadian adolescents (N = 809) aged 12-18 were recruited on social media and completed an online survey. COVID-19-related stress was associated with recent DSH. Nonacceptance of emotional responses and limited access to ER strategies fully mediated this association. The indirect effect through nonacceptance of emotional responses was stronger among more socially distanced youth, whereas the indirect effect through limited access to ER strategies was stronger among older and more socially distanced youth. COVID-19-related stress and ER difficulties did not interact to predict DSH, nor did age or social distancing moderate these interactions. These results align with etiological models proposing central roles for stress and ER difficulties in DSH. Furthermore, this study underscores a need to support adolescents, particularly older teens with reduced in-person interactions, in adaptively coping with pandemic-related stress.

Chronic medical conditions and suicidal behaviors in a nationally representative sample of American adolescents.

PURPOSE: Chronic medical conditions are a risk factor for the onset of suicidal thoughts and behaviors in adults. However, few studies have examined this association in adolescents. The present study explored the association between chronic medical conditions and the emergence of suicidal thoughts and behaviors in an adolescent sample representative of the U.S.A. METHOD: Using data from the National Comorbidity Survey-Adolescent Supplement (10,148 Americans between ages 13-17), discrete-time survival analyses were performed to examine the odds of developing suicidal ideation, planning, and attempts, given prior presence of a chronic medical condition. Multivariate models controlled for sociodemographic factors and the presence of comorbid mental health conditions. Post-hoc sensitivity analyses examined associations between timing of chronic medical condition onset and later suicidal thoughts and behaviors. RESULTS: Multivariate analyses showed that dermatological conditions, asthma, allergies, headache, and back/neck pain were associated with elevated odds of suicidal ideation, while cardiovascular conditions were associated with increased odds of suicide attempts. Additionally, cardiovascular conditions were associated with increased risk of suicide planning and attempts among adolescents with suicidal ideation. Chronic medical conditions that began in adolescence were associated with the greatest risk of later suicidal thoughts and behaviors, compared to chronic medical conditions that began in early or middle childhood. CONCLUSION: Consistent with research in middle and older adults, physical health conditions are associated with increased risk for the onset of suicidal thoughts and behaviors in adolescents. Mental health screening for adolescents with chronic medical conditions may help parents and physicians identify suicidality early.
