Parent–Adolescent Sexual Communication and Its Association With Adolescent Sexual Behaviors: A Nationally Representative Analysis in the Netherlands

Sexual communication is a principal means of transmitting sexual values, beliefs, expectations, and knowledge from parents to children. Although this area has received considerable research attention, more studies with representative samples are needed to assure that findings are reflective of populations of interest. A nationally representative sample of parent–adolescent dyads (N = 2,965; mean adolescent age = 13.8 years) in the Netherlands was employed to examine the frequency of parent–adolescent sexual communication and its association with adolescent sexual behaviors (defined as sexual initiation, condom use, and contraceptive pill use). Nine communication topics in the areas of anatomy, relationships and rights, and protection and contraception were examined. In all, 75%of parents reported having discussed at least one topic multiple times with their adolescents. Romantic relationships were discussed most frequently. Hierarchical logistic regression analyses indicated that parent–adolescent sexual communication on protection and contraception was positively associated with adolescent sexual initiation and contraceptive pill use but not condom use. This may reflect that adolescents, when they become sexually active, are more likely to discuss sexuality with their parents. Findings are interpreted within the context of Dutch culture, which is generally accepting of adolescent sexuality and characterized by open sexual communication.

BackgroundAn emerging model for sexuality education is the rights-based approach, which unifies discussions of sexuality, gender norms, and sexual rights to promote the healthy sexual development of adolescents. A rigorous evaluation of a rights-based intervention for a broad population of adolescents in the U.S. has not previously been published. This paper evaluates the immediate effects of the Sexuality Education Initiative (SEI) on hypothesized psychosocial determinants of sexual behavior.MethodsA cluster-randomized trial was conducted with ninth-grade students at 10 high schools in Los Angeles. Classrooms at each school were randomized to receive either a rights-based curriculum or basic sex education (control) curriculum. Surveys were completed by 1,750 students (N = 934 intervention, N = 816 control) at pretest and immediate posttest. Multilevel regression models examined the short-term effects of the intervention on nine psychosocial outcomes, which were hypothesized to be mediators of students’ sexual behaviors.ResultsCompared with students who received the control curriculum, students receiving the rights-based curriculum demonstrated significantly greater knowledge about sexual health and sexual health services, more positive attitudes about sexual relationship rights, greater communication about sex and relationships with parents, and greater self-efficacy to manage risky situations at immediate posttest. There were no significant differences between the two groups for two outcomes, communication with sexual partners and intentions to use condoms.ConclusionsParticipation in the rights-based classroom curriculum resulted in positive, statistically significant effects on seven of nine psychosocial outcomes, relative to a basic sex education curriculum. Longer-term effects on students’ sexual behaviors will be tested in subsequent analyses.Trial registrationClinicalTrials.gov NCT02009046.

Abstract Numerous classroom-based interventions have aimed to improve sexual health outcomes for young people, yet few have shown strong, lasting effects. Ecological approaches that address multiple levels of a young person’s environment offer largely untapped potential to positively change sexual behaviour. This paper presents results of a cluster-randomised trial of a multicomponent sexuality education intervention that integrated a classroom curriculum, parent education workshops and materials, peer advocate programme, and sexual health services at 10 urban high schools. An implementation evaluation, employing quantitative and qualitative instruments, was conducted to examine whether the individual components of the intervention were delivered as planned and how they were received by the target populations. Multilevel modelling was used to evaluate the effect of the multicomponent intervention on outcomes at one-year follow-up. Results showed that the intervention components were successfully implemented with and well received by target populations. Students receiving the multicomponent intervention reported greater increases in the use of sexual health services (odds ratio [OR] = 1.73, 95% CI = 1.09–2.75) and the likelihood of carrying a condom (OR = 2.71, 95% CI = 1.44–5.09) relative to those receiving a control condition. No effects were found for other behaviours, possibly due to low prevalence of sexual activity in the sample and the small number of schools randomised.

Factors Associated With Parent Support for Condom Education and Availability

Expanding condom-related knowledge and skills and reducing barriers to condom use have the potential to help reduce pregnancies and sexually transmitted infections among youth. These goals are sometimes addressed through condom education and availability (CEA) programs as part of sexuality education in school. Parents are a key constituency in efforts to implement such programs. A representative statewide sample of households with children (N = 1,093) in California was employed to examine parent support for CEA and the potential influences of demographics (gender, age, and Hispanic ethnicity), sociodemographics (education, religious affiliation, religious service attendance, and political ideology), and condom-related beliefs (belief in condom effectiveness and belief that teens who use condoms during sex are being responsible) on parent support for CEA. The parents in our sample reported a high level of support for CEA (M = 3.23 on a 4-point scale) and believing in a high level of condom effectiveness (M = 3.36 on a 4-point scale). In addition, 84% of the parents agreed that teens who use condoms during sex are being responsible. Hierarchical regression analyses showed that parents who were younger, Hispanic, with a lower educational attainment, without a religious affiliation, less religiously observant, and politically liberal were more supportive of CEA. After controlling for these demographic and sociodemographic factors, condom effectiveness and responsibility beliefs each added independently to the predictability of parent support for CEA. These findings suggest that parent education related to condom effectiveness could help increase support for school-based CEA programs.

Test–retest reliability of self-reported sexual health measures among US Hispanic adolescents

Objective: Although Hispanic adolescents in the USA are often the focus of sexual health interventions, their response to survey measures has rarely been assessed within evaluation studies. This study documents the test–retest reliability of a wide range of self-reported sexual health values, attitudes, knowledge and behaviours among Hispanic adolescents from low-income, urban communities. Method: Intraclass correlation coefficients were calculated for sexual health scales (knowledge, values about condom use, parent communication, protection self-efficacy and condom-use intentions) in a 2-week sample (N = 86). Cohen’s kappa and the intraclass correlation coefficients were calculated for behaviours (romantic and sexual behaviours, and sexual health services history) in two separate 2-week samples (N = 86, N = 202). Selected behaviours were also examined for retractions in both 2-week samples and in a 1-year sample (N = 291). Results: Among sexual health scales, test–retest reliability ranged from .37 for condom-use intentions to .93 for parent communication. Among behaviours, reliability ranged from 0.27 for use of sexual health services to 1.00 for use of birth control at first sex. Retractions ranged from below 10% for ever having had a steady partner to 50% or more for sexual health services and testing. Conclusion: Test–retest reliability differed greatly across self-reported sexual health values, attitudes, knowledge and behaviours for the three samples of Hispanic adolescents. Overall, however, most items and scales showed good to excellent reliability (i.e. a coefficient greater than .60), suggesting that Hispanic adolescents are moderately to highly stable reporters in response to sexual health measures.
