RESUMO
INTRODUCTION: Self-completed checklists measuring youth mental health problems produce dimensional scale scores and can be converted to categorical classifications representing the presence/absence of psychopathology. We test whether categorical classifications from scale scores are equivalent psychometrically to categorical classifications of the same problems obtained by lay-administered standardized structured diagnostic interviews. METHODS: The sample of n = 325 youth aged 12-18 (44% male) and their parent/caregivers come from combined test-retest reliability studies conducted in Ontario, Canada, from 2011 to 2015. Ontario Child Health Study Emotional Behavioural Scales-Brief Version (OCHS-EBS-B) scores converted to categorical classifications of emotional and behavioral problems were compared with interview classifications. We test hypotheses of statistical equivalence and inferiority, using a confidence interval approach to detect if differences lie within the smallest effect size of interest of ±0.18. We compare categorical classifications on: (1) test-retest reliability (Ò¡), (2) content validity (between-instrument agreement), and (3) construct validity (strength of association with three mental health-related constructs). RESULTS: Average test-retest reliabilities were 0.695 (checklists) and 0.670 (interviews). The reliability of checklist emotional problem classifications was not inferior to interview classifications and the difference in reliability between instruments for behavioral problems was small (-0.036). Average between-instrument agreement was Ò¡ = 0.586 (observed) and Ò¡ = 0.841 (corrected for attenuation due to measurement error) indicating high content overlap. Statistical equivalence criteria were met in 5 of 6 construct validity comparisons. CONCLUSIONS: Categorical classifications of emotional and behavioral problems from youth-reported checklists are, on balance, equivalent to interview classifications. Checklists represent a simple, brief, inexpensive alternative to interviews.

BACKGROUND: The standard approach for classifying child/youth psychiatric disorder as present or absent in epidemiological studies is lay-administered structured, standardized diagnostic interviews (interviews) based on categorical taxonomies such as the DSM and ICD. Converting problem checklist scale scores (checklists) to binary classifications provides a simple, inexpensive alternative. METHODS: Using assessments obtained from 737 parents, we determine if child/youth behavioral, attentional, and emotional disorder classifications based on checklists are equivalent psychometrically to interview classifications. We test this hypothesis by (1) comparing their test-retest reliabilities based on kappa (κ), (2) estimating their observed agreement at times 1 and 2, and (3) in structural equation models, comparing their strength of association with clinical status and reported use of prescription medication to treat disorder. A confidence interval approach is used to determine if parameter differences lie within the smallest effect size of interest set at ±0.125. RESULTS: The test-retest reliabilities (κ) for interviews compared with checklists met criteria for statistical equivalence: behavioral, .67 and .70; attentional, .64 and .66; and emotional, .61 and .65. Observed agreement between the checklist and interviews on classifications of disorder at times 1 and 2 was, on average, κ = .61. On average, the ß coefficients estimating associations with clinical status were .59 (interviews) and .63 (checklists); and with prescription medication use, .69 (interviews) and .71 (checklists). Behavioral and attentional disorders met criteria for statistical equivalence. Emotional disorder did not, although the coefficients were stronger numerically for the checklist. CONCLUSIONS: Classifications of child/youth psychiatric disorder from parent-reported checklists and interviews are equivalent psychometrically. The practical advantages of checklists over interviews for classifying disorder (lower administration cost and respondent burden) are enhanced by their ability to measure disorder dimensionally. Checklists provide an option to interviews in epidemiological studies of common child/youth psychiatric disorders.

OBJECTIVE: Child and youth mental health problems are often assessed by parent self-completed checklists that produce dimensional scale scores. When converted to binary ratings of disorder, little is known about their psychometric properties in relation to classifications based on lay-administered structured diagnostic interviews. In addition to estimating agreement, our objective is to test for statistical equivalence in the test-retest reliability and construct validity of two instruments used to classify child emotional, behavioural, and attentional disorders: the 25-item, parent completed Ontario Child Health Study Emotional Behavioural Scales-Brief Version (OCHS-EBS-B) and the Mini International Neuropsychiatric Interview for Children and Adolescents-parent version (MINI-KID-P). METHODS: This study draws on independent samples (n = 452) and uses the confidence interval approach to test for statistical equivalence. Reliability is based on kappa (κ). Construct validity is based on standardized beta coefficients (ß) estimated in structural equation models. RESULTS: The average differences between the MINI-KID-P and OCHS-EBS-B in κ and ß were -0.022 and -0.020, respectively. However, in both instances, criteria for statistical equivalence were met in only 5 of 12 comparisons. Based on κ, between-instrument agreement on the classifications of disorder went from 0.481 (attentional disorder) to 0.721 (emotional disorder) but were substantially higher (0.731 to 0.895, respectively) when corrected for attenuation due to measurement error. CONCLUSIONS: Although falling short of equivalence, the results suggest on balance that the reliability and validity of the two instruments for classifying child psychiatric disorder assessed by parents are highly comparable. This conclusion is supported by the high levels of agreement between the instruments after correcting for attenuation due to measurement error.

OBJECTIVES: To examine the link between stability and change in social assistance (SA) use and children's mental health trajectories to better understand whether social policies targeted at low-income families might be an effective population-based mechanism for preventing mental health problems among children at risk. METHODS: The National Longitudinal Survey of Children and Youth (N = 8981) is used to classify children into 5 categories based on their family's pattern of SA use from age 4-5 to 10-11: always or never on SA, a single transition on or off SA, or fluctuations on and off SA. Latent growth modelling is used to compare trajectories of emotional and behavioural problems among children with different patterns of SA exposure to their counterparts never on SA over this same time period. RESULTS: Child emotional and behavioural problems are exacerbated over time in accordance with patterns of SA use: chronic SA use (behavioural) and moving onto SA (emotional and behavioural). These differential rates of change result in mental health disparities at age 10-11 that were not present at age 4-5. Children exposed to SA when they were age 4-5 but subsequently moved off continue to demonstrate elevated levels of emotional and behavioural problems at age 10-11. CONCLUSIONS: Successful social policies and interventions will require understanding the specific mechanisms through which SA undermines child mental health and how programs can be modified to reduce its negative consequences.

OBJECTIVES: To quantify the strength of association between passive and active forms of screen time and adolescent major depressive episode and anxiety disorders. METHODS: Data from the 2014 Ontario Child Health Study, a representative sample of 2,320 adolescents aged 12-17 years in Ontario (mean age = 14.58, male = 50.7%) were used. Screen time was measured using adolescent self-report on time spent on screen-based activities. Past 6-month occurrence of DSM-IV-TR defined major depressive episode, social phobia, generalized anxiety disorder, and specific phobia which were assessed using the Mini International Neuropsychiatric Interview for Children and Adolescents. RESULT: Adolescents reporting 4 or more hours of passive screen time per day, compared to those reporting less than 2 h, were three times more likely to meet the DSM-IV-TR criteria for major depressive episode [OR = 3.28(95% CI = 1.71-6.28)], social phobia [OR = 3.15 (95% CI = 1.57-6.30)] and generalized anxiety disorder [OR = 2.92 (95% CI = 1.64-5.20)]. Passive screen time continued to be significantly associated with increased odds of disorders, after adjusting for age, sex, low income, active screen time use, sleep and physical activity. A small-to-moderate attenuation of the estimated ORs was observed in the fully adjusted model. In contrast, associations between active screen time use and depression and anxiety disorders were smaller in magnitude and failed to reach statistical significance. CONCLUSIONS: Passive screen time use was associated with mood and anxiety disorders, whereas active screen time was not. Further research is needed to better understand the underlying processes contributing to differential risk associated with passive versus active screen time use and adolescent mood and anxiety disorders.

PURPOSE: Although many young mothers (aged <21 years) are exposed to multiple adversities that increase their risk for mental illness, prevalence data are largely limited self-report questionnaires estimating only the prevalence of postpartum depression. Gaining a greater understanding of the burden of a broader range of common mental illnesses affecting these young women has the potential to improve their health as well as the development and functioning of their children. METHODS: The Young Mothers Health Study recruited 450 mothers aged <21 years and 100 comparison mothers (aged >20 years old at first delivery) living in urban and rural central-west Ontario. Age-matched young mothers were also compared with 15- to 17-year-old women without children (N = 630) from the 2014 Ontario Child Health Study. The prevalence of current mental disorders was assessed using the Mini-International Neuropsychiatric Interview for Children and Adolescents. RESULTS: Nearly 2 of 3 young mothers reported at least one mental health problem, and almost 40% had more than one. Young mothers were 2 to 4 times as likely to have an anxiety disorder (generalized anxiety disorder, separation anxiety disorder, social phobia, and specific phobia), attention-deficit/hyperactivity disorder, oppositional defiant disorder, or conduct disorder and were 2 to 4 times more likely to have more than one psychiatric problem than older comparison mothers or women aged 15-17 years. CONCLUSIONS: Given the high rates of mental health problems and complex needs of young mothers in Canada and the possible adverse effects of maternal psychopathology on their children, further efforts should be directed at engaging and treating this high-risk group.

There is limited empirical evidence documenting the magnitude and correlates of area-level variability in unmet need for children's mental health services. Research is needed that identifies area-level characteristics that can inform strategies for reducing unmet need in the population. The study purpose is to: (1) estimate area-level variation in children's unmet need for mental health services (using Service Areas as defined by the Ontario Ministry of Children and Youth Services), and (2) identify area-level service arrangements, and geographic and population characteristics associated with unmet need. Using individual-level general population data, area-level government administrative data and Census data from Ontario, Canada, we use multilevel regression models to analyze unmet need for mental health services among children (level 1) nested within Service Areas (level 2). The study finds that 1.64% of the reliable variance in unmet need for mental health services is attributable to between-area differences. Across areas, we find that Service Areas with more agencies had a lower likelihood of unmet need for mental health services. Compared to other Service Areas, Toronto had much lower likelihood of unmet need compared to the rest of Ontario. Rural areas, areas with unsatisfactory public transport, and areas with higher levels of socio-economic disadvantage had a higher likelihood of unmet need for mental health services. These findings identify challenges in service provision that researchers, policymakers and administrators in children's mental health services need to better understand. Policy implications and potential Service Area strategies that could address equitable access to mental health services are discussed.

BACKGROUND: Maternal exposure to socioeconomic disadvantage increases the risk of child injuries and subsequent child developmental and mental health problems - particularly for young mothers. To inform early intervention planning, this research therefore aimed to describe the health and social adversities experienced by a cohort of girls and young women in early pregnancy in British Columbia (BC), Canada. METHODS: Participants were recruited for the BC Healthy Connections Project (BCHCP), a randomized controlled trial examining the effectiveness of Nurse-Family Partnership, a home visitation program, in improving child and maternal outcomes. Baseline data were collected from 739 participants on trial entry. Participants were selected on the basis of preparing to parent for the first time and experiencing socioeconomic disadvantage. Analyses involved descriptive statistics and age-group comparisons. RESULTS: Most participants reported having low income (84%), having limited education (52%) and being single (91%) at trial entry. Beyond these eligibility criteria, other health and social adversities included: housing instability (52%); severe anxiety or depression (47%); other diagnosed mental disorders (22%); prenatal nicotine and cannabis use (27 and 21%); physical health problems (20%); child maltreatment when younger (56%); and intimate partner violence recently (50%). As well, few (29%) had received income assistance entitlements. More than two thirds (70%) were experiencing four or more forms of adversity. Age-group differences were observed for cognitive functioning, being single, low income, limited education, psychological distress and service use (p-value ≤0.05). CONCLUSIONS: This cohort was selected on the basis of socioeconomic disadvantage. Yet all participants were experiencing substantial added adversities - at higher rates than other Canadians. Furthermore, despite Canada's public programs, these pregnant girls and young women were not being adequately reached by social services. Our study adds new data to inform early intervention planning, suggesting that unacceptably high levels of socioeconomic disadvantage exist for some young British Columbians. Therefore greater health and social supports and services are warranted for these young mothers and their children. TRIAL REGISTRATION: Registered August 24, 2012 with ClinicalTrials.gov Identifier: NCT01672060 . Active not recruiting.

OBJECTIVE: To describe the methodology of the 2014 Ontario Child Health Study (OCHS): a province-wide, cross-sectional, epidemiologic study of child health and mental disorder among 4- to 17-year-olds living in household dwellings. METHOD: Implemented by Statistics Canada, the 2014 OCHS was led by academic researchers at the Offord Centre for Child Studies (McMaster University). Eligible households included families with children aged 4 to 17 years, who were listed on the 2014 Canadian Child Tax Benefit File. The survey design included area and household stratification by income and 3-stage cluster sampling of areas and households to yield a probability sample of families. RESULTS: The 2014 OCHS included 6,537 responding households (50.8%) with 10,802 children aged 4 to 17 years. Lower income families living in low-income neighbourhoods were less likely to participate. In addition to measures of childhood mental disorder assessed by the Mini International Neuropsychiatric Interview for Children and Adolescents (MINI-KID) and OCHS Emotional Behavioural Scales (OCHS-EBS), the survey contains measures of neighbourhoods, schools, families and children, and includes administrative data held by the Ministries of Education and Health and Long-Term Care. CONCLUSIONS: The complex survey design and differential non-response of the 2014 OCHS required the use of sampling weights and adjustment for design effects. The study is available throughout Canada in the Statistics Canada Research Data Centres (RDCs). We urge external investigators to access the study through the RDCs or to contact us directly to collaborate on future secondary analysis studies based on the OCHS.

OBJECTIVES: To present the 6-month prevalence and sociodemographic correlates of mental disorders and mental health-related service contacts in a sample of children (4 to 11 years) and youth (12 to 17 years) in Ontario. METHODS: The 2014 Ontario Child Health Study is a provincially representative survey of 6537 families with children aged 4 to 17 years in Ontario. DSM-IV-TR mental disorders were assessed using the Mini International Neuropsychiatric Interview for Children and Adolescents (MINI-KID) and included mood (major depressive episode), anxiety (generalized anxiety, separation anxiety, social phobia, specific phobia), and behaviour disorders (attention-deficit/hyperactivity disorder, oppositional-defiant disorder, conduct disorder).The MINI-KID was administered independently to the primary caregiver and youth aged 12 to 17 years in the family's home. RESULTS: Past 6-month prevalence of any mental disorder ranged from 18.2% to 21.8% depending on age and informant. Behaviour disorders were the most common among children, and anxiety disorders were the most common among youth. Among children and youth with a parent-identified mental disorder, 25.6% of children and 33.7% of youth had contact with a mental health provider. However, 60% had contact with one or more of the providers or service settings assessed, most often through schools. CONCLUSIONS: Between 18% and 22% of children and youth in Ontario met criteria for a mental disorder but less than one-third had contact with a mental health provider. These findings provide support for strengthening prevention and early intervention efforts and enhancing service capacity to meet the mental health needs of children and youth in Ontario.

OBJECTIVES: To examine: 1) changes in the prevalence of mental disorders and perceived need for professional help among children (ages 4 to 11) and youth (ages 12 to 16) between 1983 and 2014 in Ontario and 2) whether these changes vary by age and sex, urban-rural residency, poverty, lone-parent status, and immigrant background. METHODS: The 1983 ( n = 2836) and 2014 ( n = 5785) Ontario Child Health Studies are provincially representative cross-sectional surveys with identical self-report checklist measures of conduct disorder, hyperactivity, and emotional disorder, as well as perceived need for professional help, assessed by integrating parent and teacher responses (ages 4 to 11) and parent and youth responses (ages 12 to 16). RESULTS: The overall prevalence of perceived need for professional help increased from 6.8% to 18.9% among 4- to 16-year-olds. An increase in any disorder among children (15.4% to 19.6%) was attributable to increases in hyperactivity among males (8.9% to 15.7%). Although the prevalence of any disorder did not change among youth, conduct disorder decreased (7.2% to 2.5%) while emotional disorder increased (9.2% to 13.2%). The prevalence of any disorder increased more in rural and small to medium urban areas versus large urban areas. The prevalence of any disorder decreased for children and youth in immigrant but not nonimmigrant families. CONCLUSIONS: Although there have been decreases in the prevalence of conduct disorder, increases in other mental disorders and perceived need for professional help underscore the continued need for effective prevention and intervention programs.

OBJECTIVE: To estimate the alignment between the Ontario Ministry of Children and Youth Services (MCYS) expenditures for children's mental health services and population need, and to quantify the value of adjusting for need in addition to population size in formula-based expenditure allocations. Two need definitions are used: "assessed need," as the presence of a mental disorder, and "perceived need," as the subjective perception of a mental health problem. METHODS: Children's mental health need and service contact estimates (from the 2014 Ontario Child Health Study), expenditure data (from government administrative data), and population counts (from the 2011 Canadian Census) were combined to generate formula-based expenditure allocations based on 1) population size and 2) need (population size adjusted for levels of need). Allocations were compared at the service area and region level and for the 2 need definitions (assessed and perceived). RESULTS: Comparisons were made for 13 of 33 MCYS service areas and all 5 regions. The percentage of MCYS expenditure reallocation needed to achieve an allocation based on assessed need was 25.5% at the service area level and 25.6% at the region level. Based on perceived need, these amounts were 19.4% and 27.2%, respectively. The value of needs-adjustment ranged from 8.0% to 22.7% of total expenditures, depending on the definition of need. CONCLUSION: Making needs adjustments to population counts using population estimates of children's mental health need (assessed or perceived) provides additional value for informing and evaluating allocation decisions. This study provides much-needed and current information about the match between expenditures and children's mental health need.

OBJECTIVES: To determine if levels of neighbourhood poverty and neighbourhood antisocial behaviour modify associations between household poverty and child and youth mental health problems. METHODS: Data come from the 2014 Ontario Child Health Study-a provincially representative survey of 6537 families with 10,802 four- to 17-year-olds. Multivariate multilevel modelling was used to test if neighbourhood poverty and antisocial behaviour interact with household poverty to modify associations with children's externalizing and internalizing problems based on parent assessments of children (4- to 17-year-olds) and self-assessments of youth (12- to 17-year-olds). RESULTS: Based on parent assessments, neighbourhood poverty, and antisocial behaviour modified associations between household poverty and children's mental health problems. Among children living in households below the poverty line, levels of mental health problems were 1) lower when living in neighbourhoods with higher concentrations of poverty and 2) higher when living in neighbourhoods with more antisocial behaviour. These associations were stronger for externalizing versus internalizing problems when conditional on antisocial behaviour and generalized only to youth-assessed externalizing problems. CONCLUSION: The lower levels of externalizing problems reported among children living in poor households in low-income neighbourhoods identify potential challenges with integrating poorer households into more affluent neighbourhoods. More important, children living in poor households located in neighbourhoods exhibiting more antisocial behaviour are at dramatically higher risk for mental health problems. Reducing levels of neighbourhood antisocial behaviour could have large mental health benefits, particularly among poor children.

OBJECTIVES: To present the 12-month prevalence and correlates of suicidal ideation and attempts in a sample of youth in Ontario. METHODS: Data come from the 2014 Ontario Child Health Study, a provincially representative survey of families with children in Ontario. Youth aged 14 to 17 y ( n = 2,396) completed a computer-assisted, self-administered questionnaire in their home to assess the occurrence of suicidal ideation, suicidal attempts, and associated correlates, including non-suicidal self-injury, mental disorders, substance use, peer victimization and exposure to child maltreatment. Socio-demographic information was collected from the parent. Logistic regression models were used to identify correlates that distinguished between youth reporting: 1) no suicidal ideation or attempts, 2) suicidal ideation but no attempts, and 3) suicidal ideation and attempts. RESULTS: The 12-month prevalence of suicidal ideation and attempts was 8.1% and 4.3%, respectively. All clinical and behavioural correlates were significantly higher among youth reporting suicidal ideation or attempts, as compared with non-suicidal youth. In adjusted models, depression and non-suicidal self-injury were each independently associated with elevated odds of suicidal ideation (OR = 4.84 and 4.19, respectively) and suicidal attempt (OR = 7.84 and 22.72, respectively). Among youth who reported suicidal ideation, the only variable that differentiated youth who attempted suicide v. those who did not, in adjusted models, was non-suicidal self-injury (OR = 3.89). CONCLUSIONS: Suicidal ideation and attempts are common among youth in Ontario, often co-occurring with mental disorders and high-risk behaviours. These findings underscore the need for effective prevention and intervention strategies, particularly for youth depression and non-suicidal self-injury.

Purpose/aim: Antenatal corticosteroid (ACS) therapy has dramatically increased survival rates among extremely low birth weight (ELBW) infants. However, the long-term effects of ACS on autonomic nervous system function have not been explored. Using the world's oldest longitudinally followed cohort of ELBW infants we compared respiratory sinus arrhythmia (RSA) among ELBW survivors whose mothers received ACS (ELBW-S), those who did not (ELBW-NS) and normal birth weight (NBW) controls in their 20 and 30 s. Methods: Resting electrocardiogram (ECG) was recorded from ELBW-S (n = 28), ELBW-NS (n = 36), and matched NBW controls (n = 79) at 22-26 and 29-36 years. Resting RSA was compared across groups via analyses of covariance (ANCOVA), adjusting for sex, medication use, postnatal steroid exposure and the presence of chronic health conditions. RSA was also compared across assessments for each group. Results: At 29-36 years, resting RSA in ELBW-S was significantly lower than in NBW controls. RSA in the ELBW-NS group was intermediate between ELBW-S and NBW groups. Although the ELBW-S group also showed nominally reduced RSA compared to NBW controls at the 22-26-year visit, this difference was not statistically significant. Conclusions: ELBW survivors exposed to ACS had lower RSA than NBW controls during their 30 s, suggestive of a decline in parasympathetic input to heart. ELBW survivors who received ACS may be particularly vulnerable to cardiovascular problems in later life.

BACKGROUND: A better understanding of factors contributing to the observed variability in estimates of test-retest reliability in published studies on standardized diagnostic interviews (SDI) is needed. The objectives of this systematic review and meta-analysis were to estimate the pooled test-retest reliability for parent and youth assessments of seven common disorders, and to examine sources of between-study heterogeneity in reliability. METHODS: Following a systematic review of the literature, multilevel random effects meta-analyses were used to analyse 202 reliability estimates (Cohen's kappa = Ò¡) from 31 eligible studies and 5,369 assessments of 3,344 children and youth. RESULTS: Pooled reliability was moderate at Ò¡ = .58 (CI 95% 0.53-0.63) and between-study heterogeneity was substantial (Q = 2,063 (df = 201), p < .001 and I2 = 79%). In subgroup analysis, reliability varied across informants for specific types of psychiatric disorder (Ò¡ = .53-.69 for parent vs. Ò¡ = .39-.68 for youth) with estimates significantly higher for parents on attention deficit hyperactivity disorder, oppositional defiant disorder and the broad groupings of externalizing and any disorder. Reliability was also significantly higher in studies with indicators of poor or fair study methodology quality (sample size <50, retest interval <7 days). CONCLUSIONS: Our findings raise important questions about the meaningfulness of published evidence on the test-retest reliability of SDIs and the usefulness of these tools in both clinical and research contexts. Potential remedies include the introduction of standardized study and reporting requirements for reliability studies, and exploration of other approaches to assessing and classifying child and adolescent psychiatric disorder.

The aim of this study was to examine the link between suicidal ideation in adolescence (age 12-16) and symptoms of psychopathology in adulthood (age 22-26) in a birth cohort of extremely low birth weight (ELBW; <1000g) survivors and matched normal birth weight (NBW; >2500 g) control participants. This study utilized data from a longitudinally followed cohort of 129 ELBW survivors and 116 NBW individuals born in Ontario, Canada between the years 1977 and 1982. Participants self-reported suicidal ideation via questionnaire during adolescence (age 12-16). The depression, anxiety, inattention, and antisocial behavior subscales of the Young Adult Self Report (YASR) were used to assess symptoms of psychopathology during adulthood (age 22-26). Associations were examined in each birth weight group separately prior to and after adjustment for covariates. Before and after adjustment for covariates, suicidal ideation in NBW adolescents predicted symptoms of depression, anxiety, inattention, and antisociality in adulthood. Suicidal ideation among ELBW adolescents predicted inattentive and depressive symptoms, and antisocial behavior only before adjustment. Adolescents born at NBW who endorse suicidal ideation are at elevated risk for developing symptoms of anxiety, depression, inattention, and antisocial problems in adulthood even after adjustment. Among ELBW survivors, the risks were lower and appear to be due to confounding factors.

OBJECTIVE: To examine sex differences in the association between cyberbullying victimization and mental health (psychological distress and delinquency), substance use-related outcomes (drug and tobacco use, binge drinking), and suicide ideation among adolescents. METHOD: Data were obtained from the Ontario Student Drug Use and Health Survey (OSDUHS; 2013, N=10,272, grade 7 to 12). The sample for analysis included 4,940 students with a mean age of 15.1 years (43.3% male). A series of multi-level, binary, logistic regression models were conducted separately for female and male adolescents to quantify the strength of associations between cyberbullying victimization and study outcomes, after accounting for traditional forms of bullying and demographic covariates. RESULTS: Female adolescents reported significantly higher prevalence of cyberbullying victimization (once, 9.4%; twice or more, 13.3%) as compared with male adolescents (once, 8.3%, twice or more, 7.8%). Exposure to cyberbullying victimization was associated with an increased odds for psychological distress, suicide ideation, and delinquency among both female and male adolescents (adjusted odds ratios ranged from 1.76 to 4.63); although, the effects were more pronounced in females. Among females, but not males, the odds of reporting psychological distress, suicide ideation, and delinquency increased (in a step-wise fashion) with more frequent exposure to cyberbullying victimization. Cyberbullying victimization was associated with an increased odds of adolescent substance use only among females. CONCLUSION: Adolescents exposed to cyberbullying victimization demonstrate an increased odds of poorer mental health, substance use outcomes, and suicide ideation. The current study reveals increased risk among female adolescents as compared with male adolescents. These findings lend support for the need to develop and evaluate targeted preventative interventions specifically tailored for female and male adolescents.
