Depression and substance use in minority middle-school students.

OBJECTIVES: This study investigated the association between depression and substance use in a sample of middle-school students. METHODS: The 5721 students (59%-63% Hispanic) completed self-report items on depressive symptoms, recent smoking and binge drinking, and lifetime use of marijuana, cocaine, and inhalants. RESULTS: Symptoms of depression were strongly and positively related to substance use. For every type of use, a stepwise increase was seen between the percentage of students with low symptom frequency and the percentage of students with more symptoms. A sizable number of users reported symptoms indicating major depression. Depression scores showed few clinically meaningful differences among demographic subgroups. Substance use scores, in contrast, showed meaningful intergroup differences for racial/ethnic group and other demographic variables. CONCLUSIONS: Depressive symptoms and substance use were associated in a sample of middle-school students who were largely non-White and predominantly Hispanic. Greater understanding of the nature of this association is needed; this understanding should be used to design prevention programs, and prevention programs should be introduced at least in the middle-school years.

Outcome evaluation of a multi-component violence-prevention program for middle schools: the Students for Peace project.

This study evaluated the effect of Students for Peace, a multi-component violence-prevention intervention, on reducing aggressive behaviors among students of eight middle schools randomly assigned into intervention or control conditions. The intervention, based on Social Cognitive Theory, included the formation of a School Health Promotion Council, training of peer mediators and peer helpers, training of teachers in conflict resolution, a violence-prevention curriculum, and newsletters for parents. All students were evaluated in the spring of 1994, 1995 and 1996 (approximately 9000 students per evaluation). Sixth graders in 1994 were followed through seventh grade in 1995 or eighth grade in 1996 or both (n = 2246). Cohort and cross-sectional evaluations indicated little to no intervention effect in reducing aggressive behaviors, fights at school, injuries due to fighting, missing classes because of feeling unsafe at school or being threatened to be hurt. For all variables, the strongest predictors of violence in eighth grade were violence in sixth grade and low academic performance. Although ideal and frequently recommended, the holistic approach to prevention in schools in which teachers, administrators and staff model peaceful conflict resolution is difficult to implement, and, in this case, proved ineffective. The Students for Peace experience suggests that interventions begin prior to middle school, explore social environmental intervention strategies, and involve parents and community members.

Parental influences on students' aggressive behaviors and weapon carrying.

This article describes the association between four family constructs (family structure, relationship with parents, parental monitoring, and perception of parental attitudes toward fighting) and aggressive behaviors and weapon carrying among middle school students. Results are based on a cross-sectional survey of 8,865 6th, 7th, and 8th graders from eight urban schools in Texas (88.5% response rate). The sample was ethnically diverse. An inverse relationship was observed between aggression scores, fighting, injuries due to fighting, and weapon carrying and the family variables: parental monitoring, a positive relationship with parents, and the lack of parental support for fighting. Students who lived with both parents were less likely to report aggression than students in other living arrangements. These four family constructs accounted for almost one-third of the total variance in the aggression score. The perception of parents' attitudes toward fighting was the strongest predictor of aggression. Results provide support for including a strong parental component in the development of violence prevention programs for young people.

Padres Trabajando por la Paz: a randomized trial of a parent education intervention to prevent violence among middle school children.

This paper reports the results of a randomized trial to test the effectiveness of a theoretically derived intervention designed to increase parental monitoring among Hispanic parents of middle school students. Role model story newsletters developed through the process of Intervention Mapping were mailed to half of a subsample of parents whose children participated in Students for Peace, a comprehensive violence prevention program. The results indicated that parents in the experimental condition (N = 38) who had lower social norms for monitoring at baseline reported higher norms after the intervention than the parents in the control condition (N = 39) (P = 0.009). Children of parents in the experimental group reported slightly higher levels of monitoring at follow-up across baseline values, whereas control children who reported moderate to high levels of monitoring at pre-test reported lower levels at follow-up (P = 0.04). These newsletters are a population-based strategy for intervention with parents that show some promise for comprehensive school-based interventions for youth.

Who is violent?: factors associated with aggressive behaviors in Latin America and Spain.

The main purpose of this paper was to evaluate the strength of the association between: 1) aggressive behaviors and 2) attitudes and self-efficacy for alternatives to violence, in different cities of the Region of the Americas and Spain. Results were based on a cross-sectional house-hold survey of a sample of the population aged 18 to 70 years. The survey was conducted in eight metropolitan areas of Latin America and Spain: Rio de Janeiro, Brazil; Salvador, Bahia, Brazil; Santiago, Chile; Cali, Colombia; San José, Costa Rica; San Salvador, El Salvador; Caracas, Venezuela; and Madrid, Spain. Each sample of approximately 1,200 respondents per city was stratified by clusters and was proportional in terms of socioeconomic position and population density. In all cities and for all targets of aggression studied, people who reported using aggression were less likely to feel confident that they could solve conflicts without violence, and they were more likely to hold attitudes supporting violence. Young persons were also more likely to commit aggression against all the targets. In addition, aggression toward nonfamily members was found most frequently among young men who reported binge drinking, who either carried a firearm or would have liked to carry one, or who perceived the police as inefficient. Additional studies need to be done in each country to describe more specific attitudes associated with aggression within each subculture. Future prevention programs should focus on modifying attitudes that support violence, increasing self-efficacy in solving problems without using violence, supporting the development of a police system that people can trust, regulating firearms and access to alcohol, and raising people's education levels.

[Multicenter Study on Cultural Attitudes and Norms towards Violence (ACTIVA project): methodology]. / Estudio Multicéntrico sobre Actitudes y Normas Culturales frente a la Violencia (proyecto ACTIVA): metodología.

The purpose of this article is to describe the conceptual bases and methods used in the ACTIVA multicenter study, as well as the process employed in the different stages of the research. General information is given on the approach, design, and methods that were applied in the cities that participated in the study: San Salvador, El Salvador; San José, Costa Rica; Cali, Colombia; Caracas, Venezuela; Salvador, Bahia, Brazil; Rio de Janeiro, Brazil; Santiago, Chile; and Madrid, Spain. The objectives of the study were to: (1) analyze and compare among cities the prevalence of verbal and physical aggressive behaviors toward children, the spouse or other partner, and persons outside the family; and (2) identify personal, environmental, and socioeconomic factors associated with these violent behaviors. The purpose of the ACTIVA project was to generate information to help guide violence-prevention policies and programs in the cities and to provide criteria for decision-making, as well as to obtain baseline data to use in evaluating prevention policies and programs. To achieve the proposed objectives, a single, common questionnaire was prepared and validated. The questionnaire was used in face-to-face interviews with residents of private urban homes who were between 18 and 70 years old. The sample was selected in each city through stratified multistage sampling of clusters proportionate to the socioeconomic strata of the general population and without any substitutions. The final sample consisted of 10,821 people. In general, the response rates were within the established limits. Exceptions included San José, Rio de Janeiro, and Madrid, where the size of the final sample was slightly smaller than anticipated. More young men of higher socioeconomic strata declined to participate, so that the samples had an overrepresentation of women from medium and lower strata. The article concludes with a description of the scope and limitations of the study, in terms of both the approach and methods. With their comparative analyses, studies of this type can contribute to identifying the differences and similarities between cities. The article shows that with this method it is possible to analyze how violent behaviors are associated with different risk factors and individuals' characteristics, at a point in time. However, this design is limited in terms of establishing causal relationships, and it did not allow an evaluation of the context of every specific instance of violence.

Development of an intervention map for a parent education intervention to prevent violence among Hispanic middle school students.

This paper describes development of Padres Trabajando por la Paz, a violence prevention intervention for Hispanic parents to increase parental monitoring. The intervention was developed using an innovative new program planning process: intervention mapping. Theory and empirical evidence broadly defined performance objectives and determinants of parental monitoring. These objectives were further refined through group and individual interviews with the target parent group. Learning objectives for the intervention guided the content of the intervention that used modeling as the primary method and role model stories as a strategy delivered through newsletters. Stage-matching members of the target population for their readiness to implement the parental monitoring behaviors further refined the social cognitive message design strategies. Intervention mapping provides an explicit theory- and data-driven guide for intervention development that maximizes intervention impact for a specific target population.

The students for peace project: a comprehensive violence-prevention program for middle school students.

Students for Peace is a three-year project (October 1993- September 1996) designed to evaluate a comprehensive, school-based intervention that seeks to prevent violence among sixth-, seventh-, and eighth-grade students in a large urban school district in Texas. This study examines the hypothesis that students exposed to a two-year multiple-component intervention will reduce aggressive behavior compared to students who receive the district's "usual care" of violence prevention activities. Students for Peace is based largely on Social Learning. Theory (SLT), which addresses both the psychosocial dynamics underlying health behavior and the methods of promoting behavior change, while emphasizing cognitive processes and their effect on behavior. SLT explains human behavior in terms of a model in which three factors-behavior, social-environmental influences, and personal factors (such as personality, perceptions and expectations, and affect)-all interact. Theoretically, an individual's behavior is uniquely determined by a combination of these factors; thus, these factors become the elements for intervention strategies. The intervention program includes four main components: (1) modification of the school environment, (2) a violence-prevention curriculum, (3) peer leadership, and (4) parent education. Students for Peace is using a nested cross-sectional and cohort design in which school is the unit of design, allocation, and analysis. Eight schools, four intervention and four control, are participating. In May 1994, a questionnaire was administered to all students in school the day of the survey. A posttest evaluation was taken in the spring of 1995 and will be followed by a final posttest in spring 1996. A total of 8,865 students responded to the baseline survey. Nearly all variables indicated comparability between treatment and control conditions. As a population, Students for Peace participants are largely Hispanic (65%) or African American (19%). Violence-related variables indicated 30-day fighting prevalence, 23%; 12-month prevalence of injuries due to fighting, 14%; 30-day hand-gun carrying prevalence, 11%; 30-day prevalence of taunts and threats at school, 27%, and threats going to and from school, 26%. Overall, the data from Year 1 activities indicate a population in need of violence-prevention intervention. The challenge is to mold existing district resources into a theoretically sound program of interventions. If that program is found effective, the district will already have the necessary documentation, personnel, and skills for broader dissemination.

Violence prevention in middle schools: a pilot evaluation.

PURPOSE: To evaluate the effect of a violence prevention curriculum and of trained peer leaders on self-reported aggressive behaviors, knowledge about violence and conflict-resolution skills, self-efficacy, and attitudes among 223 6th graders. METHODS: The effect of two intervention groups (violence prevention curriculum taught by the teacher with or without the assistance of trained peer leaders) and one control group were compared. Ten 6th grade classes (four control and six intervention classes) of four middle schools participated in the study. Students were evaluated before and shortly after the implementation of the curriculum, as well as 3 months later. RESULTS: The intervention reduced self-reported aggressive behaviors among boys, but this reduction was significant only in two of the six intervention classes. Both interventions had an overall significant effect on increasing knowledge about violence and skills to reduce violence. After the intervention, students also developed a more negative attitude toward responding violently when provoked. Attitude change was stronger among students from the teacher plus peer leader group. No intervention effect was observed on self-efficacy nor on attitudes toward skills to reduce violence. Changes were not maintained over time. CONCLUSIONS: Results emphasize the need for continuous and comprehensive interventions, follow-up evaluations, and careful selection of peer leaders. Aggressive behaviors, not knowledge alone, should be used as the main dependent variable.

The co-morbidity of violence-related behaviors with health-risk behaviors in a population of high school students.

PURPOSE: To describe the frequency of violence-related behaviors and their association with other health behaviors among high school students. METHODS: The Youth Risk Behavior Survey was administered to all ninth and eleventh graders (n = 2075) of a school district in Texas. It provided information regarding violence-related behaviors and other health behaviors. Students were classified into four mutually exclusive, violence-related categories according to whether they were involved in a physical fight and/or carried a weapon. RESULTS: Overall, 20% of the students were involved in a physical fight but had not carried a weapon, 10% carried a weapon but had not been involved in a physical fight, and 17% had been involved in a physical fight and had carried a weapon. Prevalence of weapon-carrying and fighting were higher among males than females, and among ninth graders than eleventh graders. Among males, 48% had carried a weapon the month prior to the survey. Students who both fought and carried a weapon were 19 times more likely to drink alcohol six or more days than students who did not fight nor carried a weapon. Logistic regression analyses showed that drinking alcohol, number of sexual partners, and being in ninth grade were predictors of fighting. These three variables plus having a low self-perception of academic performance and suicidal thoughts were predictors of fighting and carrying a weapon. CONCLUSIONS: The data indicate that violence-related behaviors are frequent among high school students and that they are positively associated with certain health behaviors. Interventions designed to reduce violence should also address coexisting health-risk behaviors and target high-risk groups.

A comprehensive approach to school health program needs assessments.

An assessment of health promotion needs represents a fundamental step for developing comprehensive school health programs. This project developed and tested an approach for school districts to use when conducting a district-wide needs assessment of school health programs. The approach assumes a needs assessment should be multidimensional and comprehensive. Seven priority health-related behaviors were included as well as eight components of a school health program identified by Kolbe. This paper describes each aspect of the needs assessment, discusses the importance of perspectives provided by each component, and provides recommendations for districts interested in conducting an assessment.
