Environmental factors associated with adolescent antisocial behavior in a poor urban community in Brazil

Effectiveness of Community-Based Programs on Aggressive Behavior Among Children and Adolescents: A Systematic Review and Meta-Analysis

Adolescent aggressive behavior has increasingly become a central issue affecting the safety of both school campuses and the broader society. Despite the existence of numerous community interventions targeting this issue, there has been a paucity of efforts to consolidate the findings on the effectiveness of community-based programs in preventing aggressive behavior. This meta-analysis sought to address this gap by reviewing and assessing the impact of community-based initiatives on reducing adolescent aggression. A thorough search was carried out on 12 electronic databases: EBSCO, ERIC, PubMed, PsycINFO, MEDLINE, EMBASE, Scopus, Web of Science, ProQuest Dissertations and Theses, the China National Knowledge, Wanfang Databases, and China Science and Technology Journal Database. Sixteen studies were finalized, and meta-analyses were performed using a random effect model on RevMan v5.4 software developed by Cochrane. The analysis encompassed 16 published studies, involving a total of 2,585 participants. The key components of existing programs for aggression reduction included providing behavioral skills and training for adolescents, employing a problem-solving approach to address behavioral issues, offering psychological treatment, and emphasizing community supervision. The results indicate a significant positive effect of community-based interventions on aggression reduction (standardized mean difference = -0.26, 95% confidence intervals [-0.39, -0.13], Z = 3.84, p < .001). The subgroup analyses revealed that the intervention's effectiveness was moderated by the duration of the intervention, its theoretical foundation, and the sample size. This study furnishes empirical evidence supporting the enhancement of policies and practices to foster community engagement in mitigating aggressive behavior.

Mental health among adolescents exposed to social inequality in Latin America and the Caribbean: a scoping review

Background and objective

Adolescents from Latin America and the Caribbean grow up in a context of social inequality, which diminishes their well-being and leads to impaired emotional-cognitive development. To understand the problem, it is important to synthesize the available research about it. This study aims to explore the knowledge about adolescents' mental health in Latin America and the Caribbean exposed to social inequality.

Methods

A systematic scoping review was conducted encompassing a search in five databases (Medline, CINAHL, PsycINFO, Scopus, and LILACS) in June 2022. Articles of various typologies were included without time limit. After two rounds of screening, relevant data were manually extracted and synthesized into self-constructed themes using thematic analysis.

Results

Out of 8,825 retrieved records, 42 papers were included in the final review, with a predominance of quantitative approaches. The synthesis revealed two main analytical themes: (a) defining social inequality, wherein intersecting inequalities produce discrimination and determine conditions for social vulnerability; (b) social inequality and mental health, which highlights the association between socio-structural difficulties and emotional problems, amplifying vulnerability to mental ill health and poor mental health care.

Conclusion

The scientific evidence reveals that social inequality is related to impaired well-being and mental ill health on the one hand and a lack of access to mental health care on the other hand.

A scoping review of community-based mental health intervention for children and adolescents in South Asia

Children and adolescents in South Asia are exposed to significant mental health risks. Yet, policy to prevent or treat youth mental health problems in this context is underdeveloped, and services are difficult to access. Community-based mental health treatment may offer a potential solution, by increasing resource capacity in deprived settings. However, little is known about the current community-based mental health provision for South Asian youth. A scoping review was conducted across six scientific databases and hand searching of reference lists to identify relevant studies. Study selection and data extraction were performed by three independent reviewers using predefined criteria, an adapted version of the template for intervention description and replication checklist and the Cochrane Risk of Bias Tool. The search identified 19 relevant studies published from January 2000 to March 2020. Studies most frequently addressed PTSD and autism, were conducted in India and Sri Lanka, used education-based intervention and were based in urban school settings. Community-based mental health provision for the South Asian youth is in its infancy, but holds promise for providing essential resources to treat or prevent mental health disorder. New insights on approaches are discussed, which are valuable for South Asian settings, primarily task-shifting and stigma reduction, with implications for policy, practice and research.

Professional and informal help-seeking among low-income adolescents exposed to violence in the community and at school

BACKGROUND

Adolescents may seek help for many reasons beyond health needs, such as personal stress due to violence exposure.

OBJECTIVE

To investigate factors associated with receiving professional assistance and informal help due to violence exposure in the community and at school.

PARTICIPANTS AND SETTING

This study was conducted in Itaboraí, a low-income medium-size city in the State of Rio de Janeiro, Southeast Brazil, characterized by poverty, inequality and violence. It analyses data reported by 669 in-school adolescents (11-15-years, 51.7% girls).

METHODS

This is a cross-sectional study nested in a longitudinal study (Itaboraí Youth Study). The Itaboraí Youth Study involved a probabilistic community-based sample of 1409 6-to-15-year-olds based on a 3-stage probabilistic sampling plan that included a random selection of census units, eligible households and the target child.

RESULTS

Professional assistance was mainly received from psychologists (the Brazilian population has free access to health services). Family members were the main source of informal help. Correlates of professional assistance were having clinical emotional problems and not counting on an adult (if needing help) for community violence victims, and absent father for community and school violence victims. Correlates of informal help were female sex, maternal anxiety/depression and absent father for community violence victims, and younger age and higher maternal education for school violence victims.

CONCLUSIONS

The mental health needs of violence victims, and maternal difficulties to deal with the adolescent distress resulting from violence exposure (maternal increased burden due to father absence and/or having anxiety/depression) are important influences on the help-seeking process.

Home, school, and community violence exposure and emotional and conduct problems among low-income adolescents: the moderating role of age and sex

PURPOSE

The purpose of this study is to assess whether violence exposure is associated with emotional/conduct problems, when adjusting for confounders/covariates and controlling for comorbidity, and to investigate interactions between violence exposure and sex and/or age.

METHODS

This cross-sectional study evaluated a community-based sample of 669 in-school 11-15-year-olds. A three-stage probabilistic sampling plan included a random selection of census units, eligible households, and target child. Multivariable logistic regression investigated the effect of severe physical punishment by parents, peer victimization at school, and community violence on the study outcomes (adolescent-reported emotional/conduct problems identified by the Strengths and Difficulties Questionnaire/SDQ) when controlling for confounders (resilience, parental emotional warmth, maternal education/unemployment/anxiety/depression) and covariates (age, sex, stressful life events, parental rejection).

RESULTS

Considering interactions, emotional problems were associated with community violence victimization among girls, while conduct problems were associated with severe physical punishment among the younger, suffering peer aggression among the oldest, bullying victimization among girls, and witnessing community violence among boys. Desensitization (less emotional problems with greater violence exposure) was noted among the youngest exposed to severe physical punishment and the oldest who witnessed community violence.

CONCLUSION

Age and sex are moderators of the association between violence exposure and emotional/conduct problems. Interventions at local health units, schools, and communities could reduce the use of harsh physical punishment as a parental educational method, help adolescents deal with peer aggression at school and keep them out of the streets by increasing the usual five hours in school per day and making free sports and cultural/leisure activities available near their homes.

Pilot Randomized Control Trial: Efficacy of a Group-Based Psychosocial Program for Youth with PTSD in the Brazilian Favelas

The study aimed to evaluate Teaching Recovery Techniques (TRT) delivered to Brazilian youth who experienced drug violence in one Favela. Thirty children, 8 to 14 years, were randomly assigned to TRT (n = 14) or to a treatment as usual group (n = 16) involving boxing/martial arts. Youth received five 90-min sessions over successive weeks. Standardized measures assessed Posttraumatic Stress and Depression at 2 weeks pre and post-test. An exploratory assessment of posttraumatic growth was also utilized. An interview with group leaders explored perceptions of delivering TRT within the favela. Medium effect sizes were found for PTSD and Depression, and a small effect size for posttraumatic growth. Group leaders emphasized understanding the favela context for program adaptation. In conclusion, TRT was found to be effective for children with PTSD and Depression who experienced drug violence in a Brazilian favela. TRT is recommended for future delivery. Larger scale RCTs are needed in Brazilian favelas.

Emotional/Behavioral Indicators in Children and Adolescents With and Without Vocal Problems: Self-Evaluation and Parental Evaluation

OBJECTIVES

To verify the relationships between voice, behavior, and social skills in children and adolescents with and without voice disorders based on their self-reports and their parents/guardians' reports.

METHODS

The study comprised 575 individuals, with 347 parents/guardians of children and adolescents aged 6-18 years who responded the parent version of the Strengths and Difficulties Questionnaire and 228 children and adolescents aged 11-18 years, who responded its report version.

RESULTS

Children and adolescents with vocal problem scored higher on hyperactivity/inattention, emotional symptoms, peer relationship, and conduct problems domains; and in the internalization, externalization, and difficulties scales. Children with vocal problem scored lower on the skills scale in the self-report. Parents/guardians in the group with vocal problem reported peer relationship problems not perceived by their children. Parents/guardians in the group without vocal problem did not perceive the signs of hyperactivity/inattention reported in their children and adolescents' self-reports.

CONCLUSIONS

The presence of vocal problems in the pediatric and adolescent population may be a risk factor for mental health due to the higher scores on behavior problems scales, both in their internalization and externalization aspects.

Perception of Caregiving During Childhood is Related to Later Executive Functions and Antisocial Behavior in At-Risk Boys

Executive functions are considered essential for effective navigation in the social world. Parental responsiveness is a critical ingredient for normative social development and, as such, may be connected with the development of executive functions. Disruption of this development may, in turn, lead to maladaptive and antisocial behaviors. The purpose of this study was to evaluate the nature of the connections among perceived patterns of caregiving experienced in childhood, executive functions, and antisocial behaviors in at-risk adolescents. Seventy-one adolescent boys were recruited from two high-schools for adolescents who were not deemed suitable for regular schooling due to behavioral and emotional issues. Executive functions were tested using a computer-administered neuropsychological battery (CANTAB), and maternal parenting experiences and antisocial behaviors were assessed using retrospective and current questionnaires. Structural equation modeling (SEM) approach was employed to examine whether executive functions mediated the relationship between children's perceived patterns of maternal care and subsequent development of antisocial behaviors. Although maternal care had a significant direct effect on executive function (standardized coefficient = .49, p = .03) and antisocial behavior (standardized coefficient = .53, p = .05), SEM demonstrated no mediating relationships among these variables. Instead, maternal care predicted unique variance in both executive functions (standardized coefficient = .61, p = .02) and antisocial behavior (standardized coefficient = .51, p = .05). This study suggests a link between the experience of childhood caregiving and adolescent executive functions and delinquency and highlights the importance of early parenting interventions to aid executive function development. Such early interventions could potentially enhance long-term pro-social behavior.

The Effects of Victimization and Fear of Crime on the Legal Socialization of Young Adolescents in São Paulo, Brazil

It is important to understand how young adolescents come to view authorities during formative years. Experiencing, witnessing, and fearing victimization have been linked to the process of legal socialization and subsequent attitudes and behavior. In addition, procedural justice may influence adolescent perceptions of fairness of the authorities. The present study tested whether procedural justice mediated and moderated the relationship between young adolescents' direct and vicarious victimization and developing a sense of legitimacy in authority and cynicism towards authority. A longitudinal sample of 800 Brazilian students, age 11 to 12, living in São Paulo was used to fit structural equation models to examine these relationships. The findings revealed a partial link between victimization and legal socialization. The overall mediating model significantly predicted the direct and indirect relationships between victimization and fear of crime and the formation of legitimacy and cynicism. The moderating effect of procedural justice on direct victimization also significantly predicted the formation of legitimacy. Implications and future research directions are discussed.

Epidemiological profile of smoking and nicotine addiction among asthmatic adolescents

OBJECTIVE

Despite the harmful effects of cigarette smoking, this habit in asthmatic adolescents continues to be a health problem worldwide. Our objectives were to determine the epidemiological profile of smoking and the degree of nicotine dependence among asthmatic adolescents.

STUDY DESIGN

Through a cross-sectional investigation, 3383 adolescents (13-19 years of age) were studied.

METHODS

Information was collected using a previously validated questionnaire. Two study groups of adolescent smokers were formed: one composed of asthmatic adolescents and the other of healthy youths.

RESULTS

Asthmatic adolescents were found to be more likely to smoke (21.6% vs 11.8%) and to have some degree of nicotine dependence compared with healthy adolescents (51.6% vs 48.8%). The most important characteristic of smoking in asthmatic adolescents was found to be an onset before 11 years of age due to curiosity about cigarettes. Asthmatic youths continue smoking because this habit decreases their anxiety and stress. Adolescents know that smoking is addictive and often smoke on waking up in the morning or when they are sick. Yet, these adolescents do not consider smoking to be a problem.

CONCLUSION

In this study, curiosity about cigarettes was the primary reason why asthmatic adolescents smoked for the first time and developed a greater dependence to nicotine compared with healthy adolescents. Moreover, the findings show that many of the factors that favour the development of smoking are preventable, given that they are present in the family and social environment.

Mental health of children who work on the streets in Brazil after enrollment in a psychosocial program

PURPOSE

To evaluate the mental health status of children working on the streets in Sao Paulo City, Brazil, two years after their participation in a psychosocial program, and to identify factors associated with their mental health status.

METHODS

From a total sample of 126 children working on the streets, 107 (85%) were re-evaluated two years after the initiation of a psychosocial program which aimed to cease their work on the streets. The focus was the presence of mental health problems, defined based on a screening instrument (Strengths and Difficulties Questionnaire). Logistic regression models tested factors related to the probability that a child would not present mental health problems at follow-up.

RESULTS

The likelihood of a child presenting mental health problems was higher at baseline compared to the two-year follow-up (67.5 and 56.1%, respectively). Absence of mental health problems two years after a psychosocial intervention was significantly correlated with the following baseline factors: lower level of caregiver's psychiatric symptoms as measured by the SRQ (Self-Report Questionnaire) (AOR = 0.84, p = 0.0065), absence of child physical neglect (AOR = 0.38, p = 0.0705) and parental Protestant religion affiliation, compared to other religions (AOR = 4.06; p = 0.0107).

CONCLUSIONS

Different factors are related to the absence of mental health problems of children working on the streets after enrollment in a two-year psychosocial program. Our findings suggest that interventions that aim to improve child mental health should consider the detection of psychiatric symptoms in caregivers, provide treatment when it is needed, and also assess other problems such as neglect in the family setting.

Tobacco and alcohol use in adolescents with unplanned pregnancies: relation with family structure, tobacco and alcohol use at home and by friends

BACKGROUND

Recent publications show that smoking and alcohol use among adolescents with unplanned pregnancy is increasing and the causes need to be further studied.

OBJECTIVE

To determine the association between living in a non-intact family household and the presence of smokers and consumers of alcoholic beverages in the adolescents' environment with smoking and consuming alcoholic beverages in adolescents with unplanned pregnancies.

METHODS

A cross-sectional study was carried out among 785 pregnant adolescents, aged 13-19 years. Data was collected by trained interviewers using a self-administered questionnaire. The association was determined using multivariate logistic regression analysis.

RESULTS

In adolescents with unplanned pregnancies, the prevalence of active smoking was 21.2% and of alcohol consumption, 41.5%. The percentage of smoking at home was 57.4% and alcohol consumption, 77.5%. Approximately, 80.3% of adolescents with unplanned pregnancies had friends who smoked and 90.6% consumed alcoholic beverages. Multivariate logistic regression analysis shows that having friends who smoke or who consume alcoholic beverages is the most important risk factor for substance use in adolescents with unplanned pregnancies. Smoking and alcohol consumption at home are not associated with smoking in adolescents with unplanned pregnancies.

CONCLUSION

Socializing with friends who smoke and/or consume alcoholic beverages constitutes the most important risk factor for substance use among adolescents with unplanned pregnancies.

Exposure to maltreatment and urban violence in children working on the streets in São Paulo, Brazil: factors associated with street work

OBJECTIVE

To quantitatively study the exposure to childhood maltreatment and urban violence in children from families with at least one child working on the streets and to investigate the relationship between these factors and street work.

METHODS

Families who participated in a nongovernmental organization (NGO) program to eliminate child labor were included. Data concerning sociodemographic characteristics, punishment methods used in the family environment against the children, five types of abuse and neglect perpetrated by the caregivers, urban violence exposure and family functioning were collected.

RESULTS

The sample included 126 children who were working on the streets and 65 siblings who were not working on the streets. Caregivers reported high levels of severe physical punishment. The children reported high levels of abuse and neglect, and high levels of urban violence exposure. The families showed a predominance of dysfunctional and unsatisfactory relationships. A multiple logistic regression model showed that age older than 12 years and severe physical punishment at home were associated with street work.

CONCLUSION

Interventions to decrease the risk of child street work should be family-focused and should aim to reduce violence in the family environment.

Psychopathic traits in young offenders vs. non-offenders in similar socioeconomic condition

OBJECTIVE

To analyze the differences in psychopathic traits between offender and non-offender youths with similar socioeconomic backgrounds.

METHOD

The Psychopathy Checklist Revised (PCL-R) scale was used to identify whether 39 young offenders with no history of mental disorders or criteria for psychopathy exhibited differences in its total score, and specifically for factor 1 or factor 2 of this scale, when compared with 32 other young people, living in similar socioeconomic conditions, who had not committed offenses.

RESULTS

We observed statistically significant between-group differences (p < 0.01) in mean PCL-R scores, with a mean score of 13.4 in the offender group vs. 2.1 in the non-offender group. We also detected significant between-group differences when we analyzed mean factor 1 (p < 0.01) and factor 2 (p < 0.01) scores separately. Although the groups exhibited statistically significant difference in educational attainment, between-group comparison of mean PCL-R scores controlling for educational attainment by analysis of covariance (ANCOVA) showed that the difference in PCL-R scores remained statistically significant (p < 0.01).

CONCLUSIONS

We conclude that, in this sample, the presence of both primary (interpersonal/affective characteristics) and secondary (lifestyle/antisocial behavior) psychopathic traits differed between offender and non-offender youths, even when excluding psychopathy and other mental disorders from the assessments. These results suggest a need for wide-ranging interventions, not restricted to socioeconomic aspects, for the management of juvenile delinquency.

Unplanned pregnancy in adolescents: association with family structure, employed mother, and female friends with health-risk habits and behaviors

Previous publications have suggested that living in a nonintact family household and socializing with girlfriends who smoke or who consume alcoholic beverages favor the development of health-risk habits and customs in adolescents. However, their relationship with unplanned pregnancy in adolescents has not been determined. We investigated the association between family structure, employed mother, and female friends with health-risk habits and behaviors with unplanned pregnancy in adolescents (n = 3,130). After adjusting for low maternal educational level and low family income, logistic regression analyses showed that having an employed mother and socializing with girlfriends who have health-risk habits or behaviors, rather than living in a nonintact family household, appear to be the most important health-risk factors for unplanned pregnancy in adolescents. It is important for health-care programs for adolescents to be revised and for their strategies be strengthened in order to reach the objectives for which they were created.

Influence of psychosocial risk factors on the trajectory of mental health problems from childhood to adolescence: a longitudinal study

BACKGROUND

Longitudinal epidemiological studies involving child/adolescent mental health problems are scarce in developing countries, particularly in regions characterized by adverse living conditions. We examined the influence of psychosocial factors on the trajectory of child/adolescent mental health problems (CAMHP) over time.

METHODS

A population-based sample of 6- to 13-year-olds with CAMHP was followed-up from 2002-2003 (Time 1/T1) to 2007-2008 (Time 2/T2), with 86 out of 124 eligible children/adolescents at T1 being reassessed at T2 (sample loss: 30.6%).

OUTCOME

CAMHP at T2 according to the Child Behavior Checklist/CBCL's total problem scale. Psychosocial factors: T1 variables (child/adolescent's age, family socioeconomic status); trajectory of variables from T1 to T2 (child/adolescent exposure to severe physical punishment, mother exposure to severe physical marital violence, maternal anxiety/depression); and T2 variables (maternal education, child/adolescent's social support and pro-social activities).

RESULTS

Multivariate analysis identified two risk factors for child/adolescent MHP at T2: aggravation of child/adolescent physical punishment and aggravation of maternal anxiety/depression.

CONCLUSIONS

The current study shows the importance of considering child/adolescent physical punishment and maternal anxiety/depression in intervention models and mental health care policies.

Epidemiology of childhood conduct problems in Brazil: systematic review and meta-analysis

PURPOSE

This study aimed to review evidence on the prevalence of and risk factors for conduct problems in Brazil.

METHODS

We searched electronic databases and contacted Brazilian researchers up to 05/2012. Studies were included in the review if they reported the prevalence of or risk factors for conduct problems, conduct disorder, or oppositional defiant disorder for 100 + Brazilian children aged ≤18 years, systematically sampled in schools or the community. Prevalence rates and sex differences were meta-analysed. Risk factor studies were reviewed one by one.

RESULTS

The average prevalence of conduct problems in screening questionnaires was 20.8%, and the average prevalence of conduct disorder/oppositional defiant disorder was 4.1%. There was systematic variation in the results of screening studies according to methodology: recruitment location, informants, instruments, impairment criterion for case definition, and response rates. Risk factors previously identified in high-income countries were mainly replicated in Brazil, including comorbid mental health problems, educational failure, low religiosity, harsh physical punishment and abuse, parental mental health problems, single parent family, and low socioeconomic status. However, boys did not always have higher risk for conduct problems than girls.

CONCLUSIONS

Studies using screening questionnaires suggest that Brazilian children have higher rates of conduct problems than children in other countries, but diagnostic studies do not show this difference. Risk factors in Brazil were similar to those in high-income countries, apart from child sex. Future research should investigate developmental patterns of antisocial behaviour, employ a variety of research designs to identify causal risk mechanisms, and examine a broader range of risk factors.
