Occasionally the actual sample sizes were not provided by the authors of primary research, but could be estimated from the degrees of freedom reported for the statistical tests. A time period restriction was imposed because of cultural changes that occur in society—such as the AIDS epidemic—which might significantly impact the adolescent cohort and alter patterns of behavior and consequently the effects of sex education interventions. A study in Pediatrics found that parents who talk to their male children about sex are more likely to have boys who go to the doctor. It is not surprising that few psychosocial treatment studies are able to meet CONSORT criteria, commonly used in medical journals [13]. Efficacy research requires carefully specified treatment manuals [i. Furthermore, the primary articles reported very limited information about the characteristics of the parents who took part in the programs. These sub-models express relationships among variables within a given level, and specify how variables at one level influence relations occur at the other level. In general, the remaining set of predictors had a moderate degree of intercorrelation, although none of the coefficients were statistically significant. Each study was summarized and coded, and the results were tabulated by type of intervention. Discussion This review synthesized the findings from controlled sex education interventions reporting on abstinent behavior. Therefore, at this point it is not possible to affirm that parental participation per se exerts a direct influence in the outcomes of sex education programs, although clearly this is a variable that merits further study. The design addressed many deficits in published studies; it used hierarchical linear modeling to remedy the design flaws of a simple pretest-posttest analysis. The Level-1 predictor variables were pretest scores, hours, age, gender, and race. Further, the curricula undergo continual specification depending on the needs of students. This study involved 3, students nested in classrooms. Since most of the studies did not report any effect size, it had to be estimated based on the significance level and inferential statistics with formulae provided by Rosenthal Rosenthal, and Holmes Holmes; Further, the reports of political involvement in studies of abstinence education are troubling [5 , 6]. The process for the selection of studies was guided by four criteria, some of which have been employed by other authors as a way to orient and confine the search to the relevant literature Kirby et al. The first variable [i. The resulting prepost research design, while not optimal, provided a minimal level of assurance as to the effectiveness of program efforts. This yields a combined model: They were also only half as likely to have been infected with chlamydia and gonorrhea. Education effectiveness sex



The sample sizes used for the overall effect size analysis corresponded to the actual number used to estimate the effects of interest, which was often less than the total sample of the study. This study involved 3, students nested in classrooms. Discussion This review synthesized the findings from controlled sex education interventions reporting on abstinent behavior. The sample sizes used for the overall effect size analysis corresponded to the actual number used to estimate the effects of interest, which was often less than the total sample of the study. The homogeneity of effect sizes was examined to determine whether the studies shared a common effect size. Int J Psychol Behav Anal 1: Third, the outcome questionnaire also underwent changes to better reflect A-H components and 13 themes. Most of the articles published on the effectiveness of sex education programs follow the literary format of traditional narrative reviews Quinn, ; Kirby, , ; Visser and van Bilsen, ; Jacobs and Wolf, ; Kirby and Coyle, To date, too few studies have reported success in involving parents in sex education programs. This is not to say that all conference papers are defective or all journal articles are free of weaknesses. These sub-models express relationships among variables within a given level, and specify how variables at one level influence relations occur at the other level. The type of sex education intervention was defined as abstinence-oriented if the explicit aim was to encourage abstinence as the primary method of protection against sexually transmitted diseases and pregnancy, either totally excluding units on contraceptive methods or, if including contraception, portraying it as a less effective method than abstinence. According to Nash, including these skills is part of progressive trends across the country, where states have begun to require discussions of sexual consent, harassment and sexual orientation. Over the past 20 years, numerous studies have consistently demonstrated that teaching comprehensive sex education in schools doesn't have the downside most people are afraid of. Age however was not a significant predictor. The effectiveness of sex education and HIV education interventions in schools in developing countries. The overall measure of effect size reported was the corrected d statistic Hedges and Olkin, Given the discrepant results forwarded in these two recent quantitative reviews, there is a need to clarify the extent of the impact of school-based sex education in abstinent behavior and explore the specific features of the interventions that are associated to variability in effect sizes. The following is the level-2 or classroom-level model: Hedges and Olkin presented an extension of the Q statistic to test for homogeneity of effect sizes between classes QB and within classes QW Hedges and Olkin, The authors of primary research did not appear to control for nor report on the potentially confounding influence of numerous variables that have been indicated in the literature as influencing sexual decision making or being associated with the initiation of sexual activity in adolescence such as academic performance, career orientation, religious affiliation, romantic involvement, number of friends who are currently having sex, peer norms about sexual activity and drinking habits, among others Herold and Goodwin, ; Christopher and Cate, ; Billy and Udry, ; Roche, ; Coker et al. Branching from the bibliographies and reference lists in articles located through the original search provided another source for locating studies. Scores of studies decry the lack of efficacy and costs of abstinence education [1 , 2].

The scope of the implementation also appeared to moderate the effects of the interventions on abstinent behavior. Even though randomization should take care of differences in these and other potentially confounding variables, given that studies can rarely assign students to conditions and instead assign classrooms or schools to conditions, it is advisable that more information on baseline characteristics of the sample be utilized to establish and substantiate the equivalence between the intervention and control groups in relevant demographic and lifestyle characteristics. Finally, many curricula who undergo some degree of quasi-experimental investigation have shown significant effects. Of the 5 non-curriculum-based interventions, 2 of 4 adult-led and the 1 peer-led intervention improved one or more sexual behaviours. In summary, curricula were chosen with an eye towards replicability, manualization, fidelity in implementation, and adherence to federal A-H components and 13 themes. However, only parental participation and percentage of females were significant in the weighted least-squares regression analysis. We conducted a systematic review. Community interventions which recruited participants from clinical or out-of-school populations were also eliminated for the same reasons. Furthermore, 16 of the 22 interventions significantly delayed sex, reduced the frequency of sex, decreased the number of sexual partners, increased the use of condoms or contraceptives or reduced the incidence of unprotected sex. Finally, although it is rarely the case that a meta-analysis will constitute an endpoint or final step in the investigation of a research topic, by indicating the weaknesses as well as the strengths of the existing research a meta-analysis can be a helpful aid for channeling future primary research in a direction that might improve the quality of empirical evidence and expand the theoretical understanding in a given field Eagly and Wood, Efficacy research requires carefully specified treatment manuals [i. Interventions appeared to be more effective when geared to groups composed of younger students, predominantly females and those who had not yet initiated sexual activity. If the results are not significant at classroom levels, it can be inferred that the treatment effectiveness was not due to the classroom in which the students received the educational curriculum. Furthermore, 16 of the 22 interventions significantly delayed sex, reduced the frequency of sex, decreased the number of sexual partners, increased the use of condoms or contraceptives or reduced the incidence of unprotected sex. The confidence interval for parent participation does not include zero, thus indicating a small but positive effect. The primary sources for locating studies were four reference database systems: Furthermore, one-fifth of sexually active high school students had used drugs or alcohol before the most recent time they had sex. All aspects of the project were piloted and the results were examined. In general, the remaining set of predictors had a moderate degree of intercorrelation, although none of the coefficients were statistically significant. The following is the level-2 or classroom-level model: Parental participation in the program, age of the participants, virgin-status of the sample, grade level, percentage of females, scope of the implementation and year of publication of the study were associated with variations in effect sizes for abstinent behavior in univariate tests. The fourth variable [i. The sample sizes used for the overall effect size analysis corresponded to the actual number used to estimate the effects of interest, which was often less than the total sample of the study. Of these 13 studies, 11 significantly improved one or more reported sexual behaviours, and the remaining 2 showed non-significant improvements in reported sexual behaviour. The third variable [i. Interventions had to be geared to normal adolescent populations attending public or private schools in the US and report on some measure of abstinent behavior: The association between gender and effect sizes—which appeared significant both in the univariate and multivariable analyses—should be explored to understand why females seem to be more receptive to the abstinence messages of sex education interventions. This study was designed to provide access to nested data where the Level-1 were students and the Level-2 were classrooms. Further, it is important to consider anecdotes from scores of schools and programs nationwide who extol the virtues of their abstinence-education programs.

The sample sizes used for the overall effect size analysis corresponded to the actual number used to estimate the effects of interest, which was often less than the total sample of the study. The decision to record information on all the above-mentioned variables for their potential role as moderators of effect sizes was based in part on theoretical considerations and in part on the empirical evidence of the relevance of such variables in explaining the effectiveness of educational interventions. In recent years, states have begun to mandate sex ed to include information about life skills for family communication, avoiding coercion and making healthy decisions. Demographic characteristics included the following variables: A large majority of school-based sex education and HIV education interventions reduced reported risky sexual behaviours in developing countries. Health Outcomes The impact of sex education policies becomes more clear when considering that in , the United States had higher rates of teen pregnancy and sexually transmitted disease than most other industrialized countries. With a hierarchical linear model, each level in this structure is formally represented by its own sub-model. Such victory however may be misleading pyrrhic. Eleven-and-a-half percent had had four or more sexual partners. The effectiveness of sex education and HIV education interventions in schools in developing countries. Having those condoms available does seem to encourage teens to use them, but only if they would be having sex anyway. Three-quarters of the participants were Caucasian while the remainder were equally split between African-Americans and Hispanic students. The Level-2 predictor variable was class size, an interval and grand-mean centered variable. This yields a combined model: Thus, successful programs have been reported from a widespread sampling of educators within diverse settings in diverse educational curricula administered to diverse student populations [15]. The criteria to define eligibility of studies were the following. In terms of the characteristics of the programs, the features coded were: Further, the curricula undergo continual specification depending on the needs of students. A one-way ANOVA with random effects provided useful preliminary information about how much variation in the outcome [i. Implications for the findings are stated with recommendations for further research. In these times of precocious pre-teens, pregnancy among teenagers, and sexually transmitted diseases and infections STDs , children and adolescents need much more than a one-time chat about the birds and the bees. Thus, the first year consisted of an iterative process to prepare for a roll out in the second year that included the current curriculum, activities, and outcome measures. Studies that reported on interventions designed for cognitively handicapped, delinquent, school dropouts, emotionally disturbed or institutionalized adolescents were excluded from the present review since they address a different population with different needs and characteristics. Even though the U. However, for the rest of the variables, no similar assumptions seemed appropriate, and therefore if no pertinent data were reported for a given variable, it was coded as missing see Table I.

The limited number of effect sizes precluded such analysis. Thus, abstinence-education providers can claim that their programs are effective, if not efficacious. However, for the rest of the variables, no similar assumptions seemed appropriate, and therefore if no pertinent data were reported for a given variable, it was coded as missing see Table I. In the first review Frost and Forrest, , the authors selected only five rigorously evaluated sex education programs and estimated their impact on delaying sexual initiation. Gender was also a significant predictor of posttest scores. As it has been stated, the exploration of moderator variables could be performed only partially due to lack of information on the primary research literature. A limitation to the coding of these and of other potentially relevant and interesting moderator variables was the scantiness of information provided by the authors of primary research. Before the new law went into effect last January , California left sex education as an optional component of health curricula for students in grades 7 through The overall measure of effect size reported was the corrected d statistic Hedges and Olkin, This study involved 3, students nested in classrooms. The overall mean effect size for abstinent behavior was very small, close to zero. Finally, although it is rarely the case that a meta-analysis will constitute an endpoint or final step in the investigation of a research topic, by indicating the weaknesses as well as the strengths of the existing research a meta-analysis can be a helpful aid for channeling future primary research in a direction that might improve the quality of empirical evidence and expand the theoretical understanding in a given field Eagly and Wood, The discrepancy between these two quantitative reviews may result from the decision by Franklin et al. Coding of the studies for exploration of moderators The exploration of study characteristics or features that may be related to variations in the magnitude of effect sizes across studies is referred to as moderator analysis. In general, the remaining set of predictors had a moderate degree of intercorrelation, although none of the coefficients were statistically significant. Only one of the interventions a non-curriculum-based peer-led intervention increased any measure of reported sexual intercourse; 7 interventions delayed the reported onset of sex; 3 reduced the reported number of sexual partners; and 1 reduced the reported frequency of sexual activity. Therefore, at this point it is not possible to affirm that parental participation per se exerts a direct influence in the outcomes of sex education programs, although clearly this is a variable that merits further study. It is not surprising that few psychosocial treatment studies are able to meet CONSORT criteria, commonly used in medical journals [13]. Literature search and selection criteria The first step was to locate as many studies conducted in the US as possible that dealt with the evaluation of sex education programs and which measured abstinent behavior subsequent to an intervention. It may be the case that in large-scale studies it becomes harder to control for confounding variables that may have an adverse impact on the outcomes. In any long-term study of any intervention modality, it is important to consider plausible threats to conclusions of effectiveness and efficacy. All predictors were entered simultaneously. The second variable [i. Abstract Background: The test of model specification yielded a significant QE statistic suggesting that the two-predictor model cannot be regarded as correctly specified see Table IV.

Thus, HLM was used in this particular study to help improve the estimation of individual effects, to formulate and test hypotheses about how variables measured at one level affect relations occurring at another level, and to estimate the variance and covariance components with nested data. Only one of the interventions a non-curriculum-based peer-led intervention increased any measure of reported sexual intercourse; 7 interventions delayed the reported onset of sex; 3 reduced the reported number of sexual partners; and 1 reduced the reported frequency of sexual activity. In the first review Frost and Forrest, , the authors selected only five rigorously evaluated sex education programs and estimated their impact on delaying sexual initiation. For most programs currently implemented in the US, a delay in the initiation of sexual activity constitutes a positive and desirable outcome, since the likelihood of responsible sexual behavior increases with age Howard and Mitchell, Testing for homogeneity required the calculation of a homogeneity statistic, Q. The scope of the implementation also appeared to moderate the effects of the interventions on abstinent behavior. Parents who were willing to participate might differ in important demographic or lifestyle characteristics from those who did not participate. Introduction Any casual reader of the literature on abstinence education would be bewildered at the acrimony that exists between comprehensive sexual education and abstinence only education proponents. Research in sex education could be greatly improved if more efforts were directed to test interventions utilizing randomized controlled trials, measuring intervening variables and by a more careful and detailed reporting of the results. The following is the level-1 or student-level model: Introduction Sexually active teenagers are a matter of serious concern. Having those condoms available does seem to encourage teens to use them, but only if they would be having sex anyway. As it has been stated, the exploration of moderator variables could be performed only partially due to lack of information on the primary research literature. With a hierarchical linear model, each level in this structure is formally represented by its own sub-model. The resulting prepost research design, while not optimal, provided a minimal level of assurance as to the effectiveness of program efforts. Even considering only published studies, it may be difficult to detect duplication. The descriptive statistics for the outcome, the studentlevel and classroom-level variables are presented in Table 1. A possible explanation for this trend may be the expansion of mandatory sex education in the US which makes it increasingly difficult to find comparison groups that are relatively unexposed to sex education. The results of the univariate analyses were used to select the predictors to be included in the model. The curriculum-based interventions having the characteristics of effective interventions in the developed and developing world should be implemented more widely. With a hierarchical linear model, each level in this structure is formally represented by its own sub-model. Abstinence-only education doesn't affect the rates at which teenagers decide to have sex. Interventions appeared to be more effective when geared to groups composed of younger students, predominantly females and those who had not yet initiated sexual activity. Introduction Sexually active teenagers are a matter of serious concern. Although this study did not go to the level of measuring impact, it did provide a methodological argument by which impact can be inferred. In terms of the characteristics of the programs, the features coded were: The Level-1 predictor variables were pretest scores, hours, age, gender, and race. To ensure that there was not observer drift, two staff members were present throughout these fidelity checks.

Only one effect size from each pair of articles was included to avoid the possibility of data dependence. Finally, an added advantage of including only published articles is that it helps reduce the risk of data dependence. The effect of six student-level predictor variables [i. During the first year of funding, the project team hired staff, finalized relationships with site administrators, purchased abstinence education curriculum, created measures, and trained facilitators. The second variable [i. A possible explanation for this trend may be the expansion of mandatory sex education in the US which makes it increasingly difficult to find comparison groups that are relatively unexposed to sex education. For parental participation, no missing values were present because a decision was made to code all interventions which did not specifically report that parents had participated—either through parent—youth sessions or homework assignments—as non-participation. The overall mean effect size for abstinent behavior was very small, close to zero. For the purposes of this review the probability level chosen for significance testing was 0. Among the set of categorical predictors studied, parental participation in the program, virginity status of the sample and scope of the implementation were statistically significant. A one-way ANOVA with random effects provided useful preliminary information about how much variation in the outcome [i. The goals were to: As it has been stated, the exploration of moderator variables could be performed only partially due to lack of information on the primary research literature. Unfortunately, most of the research in the area of sex education do not employ experimental or quasi-experimental designs and thus fall short of providing conclusive evidence of program effects. These authors recommend this measure since it does not overestimate the population effect size, especially in the case when sample sizes are small. Even though randomization should take care of differences in these and other potentially confounding variables, given that studies can rarely assign students to conditions and instead assign classrooms or schools to conditions, it is advisable that more information on baseline characteristics of the sample be utilized to establish and substantiate the equivalence between the intervention and control groups in relevant demographic and lifestyle characteristics. When multiple variations of interventions were tested, the effect size was calculated for the most successful of the treatment groups. Abstract Background: Such victory however may be misleading pyrrhic. It may well be that abstinence educators have altered their programs in response to withering criticism. The Level-2 predictor variable was class size, an interval and grand-mean centered variable. Results A fully unconditional HLM was used to gather preliminary information about the reliability estimate of overall classroom means of posttest scores and the amount of variation in posttest scores that lies within and between classrooms in the sample. The larger effects associated to small-scale trials seems worth exploring. In the second review, Franklin et al. Finally, many curricula who undergo some degree of quasi-experimental investigation have shown significant effects. In terms of the design and implementation of sex education interventions, it is worth noting that the length of the programs was unrelated to the magnitude in effect sizes for the range of 4. Advanced Search Abstract This review presents the findings from controlled school-based sex education interventions published in the last 15 years in the US.

The Level-1 outcome variable was posttest scores. Studies that reported on interventions designed for cognitively handicapped, delinquent, school dropouts, emotionally disturbed or institutionalized adolescents were excluded from the present review since they address a different population with different needs and characteristics. Author information: Just like abstinence-only programs, good comprehensive programs teach students that abstinence is the only surefire way to prevent pregnancy and STDs. One remedy to lessen this focus on ideology is to provide a broader analysis of program efforts. Health Outcomes The impact of sex education policies becomes more clear when considering that in , the United States had higher rates of teen pregnancy and sexually transmitted disease than most other industrialized countries. Thus, abstinence-education providers can claim that their programs are effective, if not efficacious. Even considering only published studies, it may be difficult to detect duplication. Teachers feel pressure from parents to deliver just the right amount of information, but students tune out when educators fail to address their individual questions. Published studies which were known or suspected to have employed the same database were only included once. The Level-2 predictor variable was class size, an interval and grand-mean centered variable. In the weighted least-squares regression analysis, only parental participation and the percentage of females in the study were significant. Such victory however may be misleading pyrrhic. Interventions had to be geared to normal adolescent populations attending public or private schools in the US and report on some measure of abstinent behavior: However, given that recent evidence indicates that weaker designs yield higher estimates of intervention effects Guyatt et al. Authors of reviews uniformly conclude that abstinence-only studies lack credibility because they fail standards of adequate efficacy research methods [10 , 11 , 7]. Table I. Among the set of categorical predictors studied, parental participation in the program, virginity status of the sample and scope of the implementation were statistically significant. A possible explanation for this trend may be the expansion of mandatory sex education in the US which makes it increasingly difficult to find comparison groups that are relatively unexposed to sex education. Abstinence-only education doesn't affect the rates at which teenagers decide to have sex. The information retrieved from the articles for its potential inclusion as moderators in the data analysis was categorized in two domains: The third variable [i. As a way of understanding this wide variation in beliefs, some writers [8 , 9] suggest that this ongoing controversy is akin to a morality play in which religious beliefs are at the heart of adherence to a choice of curriculum.

Only two moderators—parental participation and percentage of females—appeared to be significant in both univariate tests and the multivariable model. This study involved 3, students nested in classrooms. The fourth variable [i. We conducted a systematic review. Presumably, this type of study begins the process of unpackaging the black box of abstinence education efforts. For the purposes of this review the probability level chosen for significance testing was 0. Finally, although it is rarely the case that a meta-analysis will constitute an endpoint or final step in the investigation of a research topic, by indicating the weaknesses as well as the strengths of the existing research a meta-analysis can be a helpful aid for channeling future primary research in a direction that might improve the quality of empirical evidence and expand the theoretical understanding in a given field Eagly and Wood, Research in educahion deal could education effectiveness sex fully improved if more hours were passe to seat windows having randomized controlled trials, assembly fuming variables and effeftiveness a more dependable and detailed femininity of the us. In addition to these computers, the two-way lass of age and group, the three-way boon effectivenes age, press and tell was also considered. Previous se were trendy as dummy mistakes.
