Intrapersonal and Interpersonal Factors Influencing Adolescents' Decisions About Having Sex: A Test of Sufficiency of the Theory of Planned Behavior

Personal Social Networks and Relapses in Women With Substance Dependence: Application of the Theory of Planned Behavior

OBJECTIVE

Establishing positive network resources and rebuilding drug free networks are key components of recovery process for women with substance use disorder (SUDs). Theory of planned behavior (TPB) posits that behaviors are determined by behavioral intentions, which are determined by three factors: attitude toward the behavior, perceived behavioral control, and subjective norms. The current study applied TPB to examine whether women's personal social network characteristics (as subjective norms) were related to intentions towards, and/or a substance use relapse using prospective research design.

METHODS

Longitudinal data from 300 American women with SUD who received treatment at three county-funded, women-only intensive treatment programs was utilized for the current study.

RESULTS

Bayesian estimation path analyses indicated that attitude and abstinence self-efficacy at intake were not related to intention at the 6-month follow-up, but abstinence self-efficacy was directly related to substance use relapse by 12 months. Personal social network characteristics, number of treatment related persons in personal social network and sobriety support were significantly associated with intention at 6 months. The interaction between the numbers of treatment related persons and density was found on intention, suggesting that density strengthens the relationship between treatment related persons in network and intention. Intention to use substance was associated with relapse to substance use behavior.

CONCLUSION

Our findings support that personal social network characteristics can be considered as subjective norms in the TPB model. Personal social network interventions focusing on rebuilding consistent social norms against drug-using behaviors may decrease intention to use substance, which will lead to abstinence.

Parent-adolescent sexual dialogue

Purpose

The purpose of this paper is to explore how the content and approach of parent-adolescent communication about sexuality were associated with three adolescent sexuality variables (sexual attitudes, combination of all behaviors and advanced behaviors).

Design/methodology/approach

Survey research with adolescents was conducted in classrooms at school. Participants were 473 adolescents (196 males, 253 females and 24 unreported) in grades 9–12 from two high schools (one urban and one suburban) in a large midwestern city.

Findings

Adolescents who described their parents’ communication approach as open, or who did not engage in conversations about sexuality with their parents reported lower rates of sexual behavior, when compared to adolescents whose parents dictated such conversations. Females were found to have more conservative sexual attitudes than males, and both mothers and fathers were found to have a direct role in talking to their children about sexuality.

Originality/value

Findings from the study may offer guidance to parents and help adults aiming to empower youth to make healthy sexual decisions.

Correlates of Young Men's Intention to Discuss Birth Control with Female Partners

CONTEXT

Heterosexually active men who wish to prevent conception, but are not willing to use condoms consistently, need to discuss birth control with female partners. Improving the understanding of correlates of men's intention to have such discussions is one step toward supporting this health-facilitating behavior.

METHODS

A sample of 372 heterosexually active men aged 18-25 were recruited and surveyed online between December 2010 and June 2011. Men answered questions on attitudes toward, norms regarding and self-efficacy about discussing birth control, and about endorsement of two sexual scripts. Multiple regression analyses tested these measures' associations with intention to discuss birth control, controlling for age and relationship status.

RESULTS

Attitudes, norms and self-efficacy were each positively associated with men's intention to discuss birth control, accounting for 34% of variance. The more strongly men endorsed a traditional masculinity sexual script, the less likely they were to intend to discuss birth control (coefficient, -0.2). Endorsement of an alternative, gender-equitable "sex-positive woman" script, which emphasizes sexual pleasure and emotional connection as goals for both partners, had no association with intention.

CONCLUSION

Strategies that merit further exploration as potential supports for men's intention to discuss birth control include improving men's self-efficacy and positive attitudes and norms pertaining to such discussions, and reducing belief in traditionally masculine sexual scripts or transforming them to include discussing birth control. Future research should work both experimentally and longitudinally to document each element of the process that ends with men's full participation in effective contraceptive use.

Predicting the Intention to Use Condoms and Actual Condom Use Behaviour: A Three-Wave Longitudinal Study in Ghana

BACKGROUND

Growing cross-sectional research shows that the theory of planned behaviour (TPB) is robust in predicting intentions to use condoms and condom use behaviour. Yet, little is known about the TPB's utility in explaining intentions to use condoms and condom use behaviour over time.

METHODS

This study used a longitudinal design and latent variable structural equation modelling to test the longitudinal relationships postulated by the TPB. School-going youths in Ghana provided data on attitudes, subjective norms, perceived control, intentions, and behaviour regarding condom use at three time points, spaced approximately three months apart.

RESULTS

As predicted by the TPB, the results showed that attitudes were significantly positively associated with intentions to use condoms over time. Contrary to the TPB, subjective norms were not significantly associated with intentions to use condoms over time. Perceived control did not predict intentions to use condoms over time. Moreover, intentions to use condoms were not significantly associated with self-reported condom use over time.

CONCLUSION

These results suggest that school-going youths in Ghana may benefit from sex education programmes that focus on within-subject attitude formation and activation. The theoretical and methodological implications of these results are discussed.

Perceived Costs and Benefits of Early Childbearing: New Dimensions and Predictive Power

CONTEXT

Understanding the causes of early childbearing is important for reducing the persistently high rates of early births in the United States. Perceptions of possible benefits may contribute to these rates, while high opportunity costs may dissuade women from early childbearing.

METHODS

Perceptions of costs and benefits of pregnancy, as well as later experiences of pregnancy, were assessed for 701 nulligravid women aged 18-22 who entered the Relationship Dynamics and Social Life study in 2008-2009 and were interviewed weekly for up to 30 months. Bivariate t tests, chi-square tests and multivariable discrete-time event history analyses were used to assess associations of perceived personal consequences of childbearing (e.g., predicted financial costs), goals in potentially competing domains (opportunity costs) and social norms with subsequent pregnancy.

RESULTS

Twenty percent of women reported that early childbearing would have more positive than negative personal consequences. Compared with other women, those who had a pregnancy during follow-up had, at baseline, more positive perceptions of the personal consequences of pregnancy and of their friends' approval of pregnancy, and greater desire for consumer goods. In multivariable analyses, only the scales assessing perceived personal consequences of childbearing and friends' approval of childbearing were associated with pregnancy (odds ratios, 2.0 and 1.2, respectively). Goals in potentially competing domains were not associated with pregnancy.

CONCLUSION

Young women's perceptions of consequences of early childbearing predict subsequent pregnancy. That these perceptions are distinct from childbearing desires and from other dimensions of costs and benefits illustrates the complex attitudinal underpinnings of reproductive behavior.

Young adolescents' sexual and romantic reference displays on Facebook

PURPOSE

Social networking sites (SNSs) form increasingly popular venues for adolescents to express their developing identity, including their sexual self. This study investigated how and to what extent early and middle adolescents display sexuality and romance on SNSs and the demographic and psychosexual factors associated with their displays.

METHODS

Dutch adolescents aged 11-18 years were recruited and Facebook friended. Participants' Facebook profiles were evaluated for sexual and romantic references and Facebook engagement. Participants completed a digital questionnaire measuring constructs related to romantic and sexual development. Analyses included chi-square and Student's t-tests.

RESULTS

A total of 104 adolescents (M(age) = 15.01, 68.3% female) were Facebook friended. Of 104 profiles, 25 (24.0%) contained 67 sexual references, and 27 (26.0%) contained 204 romantic references. Sexual references were mostly posted by others and referring to others or to no one in particular, whereas romantic references were predominantly posted by and referring to the profile owner. Displayers of sexual and romantic references were, compared with nondisplayers, older, more engaged in Facebook, more sexually experienced, and perceived more of their peers as approving of sex and as sexually active. In addition, sexual displayers were more likely boys and more sexually interested. There were no differences with respect to sexual intention and sexual attitudes.

CONCLUSIONS

A minority of young adolescents display sexual and romantic references on SNSs. References may reflect adolescents' offline sexual and romantic experiences. Yet, they may be powerful in creating behavioral norms; therefore, guidance on interpreting and displaying such messages should be promoted.

A meta-analytic review of the relationship between adolescent risky sexual behavior and impulsivity across gender, age, and race

BACKGROUND

Impulsivity is frequently included as a risk factor in models of adolescent sexual risk-taking; however, findings on the magnitude of association between impulsivity and risky sexual behavior are variable across studies. The aims of the current meta-analysis were to examine (1) how specific impulsivity traits relate to specific risky sexual behaviors in adolescents, and (2) how the impulsivity-risky sex relationship might differ across gender, age, and race.

METHOD

Eighty-one studies were meta-analyzed using a random effects model to examine the overall impulsivity-risky sex relationship and relationships among specific impulsivity traits and risky sexual behaviors.

RESULTS

Overall, results revealed a significant, yet small, association between impulsivity and adolescent risky sexual behavior (r=0.19, p<0.001) that did not differ across impulsivity trait. A pattern of stronger effects was associated with risky sexual behaviors as compared to negative outcomes related to these behaviors. Gender moderated the overall relationship (β=0.22, p=0.04), such that effect sizes were significantly larger in samples with more females. Age, race, study design, and sample type did not moderate the relationship, although there was a pattern suggesting smaller effects for adolescents in juvenile detention settings.

CONCLUSIONS

Adolescent samples with more females showed a larger impulsivity-risky sex relationship, suggesting that impulsivity may be a more important risk factor for risky sex among adolescent females. Research and treatment should consider gender differences when investigating the role of impulsivity in adolescent sexual risk-taking.

A Meta-Analysis of the Relations Between Three Types of Peer Norms and Adolescent Sexual Behavior

The aim of the present meta-analysis was to investigate the associations between three types of peer norms-descriptive norms (peer sexual behaviors), injunctive norms (peer sexual attitudes), and peer pressure to have sex-and two adolescent sexual behavior outcomes (sexual activity and sexual risk behavior). Adolescent sexual activity was more strongly associated with descriptive norms (ESrfixed=.40) than with injunctive norms (ESrfixed=.22) or peer pressure (ESrfixed=.10). Compared with the sexual activity outcome, the effect size for descriptive norms (peer sexual risk behavior) for sexual risk behavior was smaller (ESrfixed=.11). Age, gender, peer type, and socio-cultural context significantly moderated these associations. Additional analyses of longitudinal studies suggested that selection effects were stronger than socialization effects. These findings offer empirical support for the conceptual distinction between three types of peer norms and hold important implications for theory, research, and intervention strategies.

Parents as moderators of longitudinal associations between sexual peer norms and Dutch adolescents' sexual initiation and intention

PURPOSE

The present study investigated how parents and peers interact in promoting or delaying Dutch adolescents' sexual initiation and intention and focused specifically on parents as moderators of peer influence.

METHODS

Using a longitudinal design, two waves of online questionnaire data were collected among 900 Dutch adolescents (M = 13.8 years at T1), who were sexually inexperienced at baseline. At T1, participants reported on three types of perceived sexual peer norms: friends' sexual behaviors (descriptive norms), friends' sexual attitudes (injunctive norms), and experienced peer pressure to have sex. They also rated two parenting aspects at T1: the general quality of their relationship with parents and the frequency of sexuality-specific communication with their parents. Six months later, the participants reported on their experience with different sexual behaviors ranging from naked touching or caressing to intercourse and their intention to have sex in the next school year.

RESULTS

Relationship quality with parents was significantly associated with both outcomes, with a higher relationship quality predicting smaller odds of sexual initiation and less intention to have sex. Two significant interaction effects showed that frequent sexual communication with parents significantly reduced the effects of sexually active friends and experienced peer pressure on adolescents' intention to have sex.

CONCLUSIONS

Our findings show that different types of sexual peer norms and both general and sexuality-specific parenting play an important role in the early stages of Dutch adolescents' sexual trajectories. Moreover, parent-adolescent communication about sexuality can function as a buffer for the sex-stimulating effects of sexual peer norms.

Education in entrepreneurship and the Theory of Planned Behaviour

Purpose

– The purpose of the present empirical study is to investigate the relationship between education in entrepreneurship and entrepreneurial behaviour and compare the effectiveness of frequently used entrepreneurship education teaching approaches.

Design/methodology/approach

– Hypotheses are derived from the “Theory of Planned Behaviour” (“TPB”), which suggests that education in entrepreneurship is positively related to attitude (“A”), subjective norm (“SN”) and perceived behavioural control (“PBC”); that the effect on A, SN and PBC is stronger for extensive courses in entrepreneurship than for more superficial forms of educational efforts; and that education only influences entrepreneurial intentions indirectly through the effect on A, SN and PBC. The hypotheses are tested using data from two different surveys, one from Belgium and one from Norway.

Findings

– None of the hypotheses are supported. However, the findings from the study indicate a strong direct relationship between participation in extensive education programmes in entrepreneurship and entrepreneurial intention.

Research limitations/implications

– Additional empirical evidence would be required to confirm these results and help to improve our understanding of the validity bounds of the TPB in the field of entrepreneurship.

Practical implications

– The findings indicate that educational programs or events of limited duration have a rather limited usefulness and that efforts should rather be directed on programs of longer duration. This would, for instance, speak for a re-orientation of some policies like those financing short seminars on venture creation for unemployed people.

Originality/value

– Using data from two different surveys, one from Belgium and one from Norway, this study raises questions about the sufficiency of the TPB.

Comparing the Utility of the Theory of Planned Behavior Between Boys and Girls for Predicting Snack Food Consumption

The purpose of this study was to use the theory of planned behavior to explain two types of snack food consumption among boys and girls (girls n = 98; boys n = 69), which may have implications for future theory-based health promotion interventions. Between genders, there was a significant difference for calorie-dense/nutrient-poor snacks ( p = .002), but no difference for fruit and vegetable snacks. Using stepwise multiple regression, attitudes, perceived behavioral control, and subjective norms accounted for a large amount of the variance of intentions (girls = 43.3%; boys = 55.9%); however, for girls, subjective norms accounted for the most variance, whereas for boys, attitudes accounted for the most variance. Calories from calorie-dense/nutrient-poor snacks and fruit and vegetable snacks were also predicted by intentions. For boys, intentions predicted 6.4% of the variance for fruit and vegetable snacks ( p = .03) but was not significant for calorie-dense/nutrient-poor snacks, whereas for girls, intentions predicted 6.0% of the variance for fruit and vegetable snacks ( p = .007), and 7.2% of the variance for calorie-dense/nutrient-poor snacks ( p = .004). Results suggest that the theory of planned behavior is a useful framework for predicting snack foods among children; however, there are important differences between genders that should be considered in future health promotion interventions.

Predicting Mexican youths' intention to engage in risky behaviors: applying moral norms to the theory of planned behavior

This study explored if moral norms as applied to the theory of planned behavior (TPB) account for additional variance in predicting intention to consume alcohol, smoke cigarettes, and engage in sexual activity among youth at a high school in Mexico. Additionally, it investigated if moral norms provide a moderating influence on the constructs of the theory: attitude, subjective norm, and perceived behavioral control for prediction of risky behavior intention. Multiple regression analyses identified predictive power of constructs; interactions of moral norms with the theory constructs were studied. Moral norms only significantly predicted sexual activity. Significant interactions were found between moral norms and the theory constructs for the three behaviors. Interventions aimed at preventing risky conduct among youth would benefit from strategies targeting beliefs in the moral order, especially because of its interaction with the other theoretical mechanisms.

Young mothers' decisions to use marijuana: a test of an expanded Theory of Planned Behaviour

The current study examines the Theory of Planned Behaviour's (TPB) ability to predict marijuana use among young women who experienced a premarital pregnancy before the age of 18 years, using longitudinal data. The validity of the TPB assumption that all other variables work through TPB constructs is also tested. Indicators of four constructs that have been shown in the literature to be predictive of marijuana use-persistent environmental adversity, emotional distress, adolescent marijuana use and drug use in the social network-were tested as predictors of attitudes, norms and self-efficacy, in a structural equation modelling framework. All paths from distal predictors were through the mediating TPB constructs, in accordance with the tenets of the model. Implications of these findings for the TPB model and for understanding factors that lead to marijuana use are discussed.

The Role of Communication with Friends in Sexual Initiation

This study identifies a theoretical mechanism through which communication with friends about sex influences sexual initiation in a sample of adolescents. The Integrative Model was used to assess the effect of attitudes, normative pressure and self efficacy on intentions to have sex in a sample of virgin adolescents. Results show that the constructs of the theory partially mediated the effect of communication with friends on subsequent sexual initiation. The effect of communication with friends on sexual initiation was not different for males and females. Overall, the results suggest how conversations with friends about sex influence adolescents' intentions to initiate sexual intercourse, which in turn influence subsequent sexual initiation.

Differentiating between precursor and control variables when analyzing reasoned action theories

This paper highlights the distinction between precursor and control variables in the context of reasoned action theory. Here the theory is combined with structural equation modeling to demonstrate how age and past sexual behavior should be situated in a reasoned action analysis. A two wave longitudinal survey sample of African-American adolescents is analyzed where the target behavior is having vaginal sex. Results differ when age and past behavior are used as control variables and when they are correctly used as precursors. Because control variables do not appear in any form of reasoned action theory, this approach to including background variables is not correct when analyzing data sets based on the theoretical axioms of the Theory of Reasoned Action, the Theory of Planned Behavior, or the Integrative Model.
