A Noncausal Relation Between Casual Sex in Adolescence and Early Adult Depression and Suicidal Ideation: A Longitudinal Discordant Twin Study

Research on relations between casual sex and mental health is inconclusive; while some studies indicate casual sex may lead to more negative mental health (e.g., depression), other studies report no such relationship. Using a genetically informed approach, this study examined whether earlier casual sex (i.e., ever engaging in casual sex and number of casual sex partners) in adolescence has a causal influence on later mental health in young adulthood (i.e., depressive symptoms and suicidal ideation), as well as the reverse relationship (adolescent negative mental health on young adult casual sex) by exploiting the quasi-experimental nature of discordant-twin models. Multilevel models that measured within-twin and between-twin pair effects of adolescent casual sex were estimated, using 714 twins (357 twin pairs) from the sibling subsample of the National Longitudinal Study of Adolescent Health (Add Health). Results indicated that there was no causal relationship between casual sex in adolescence and higher levels of depressive symptoms or suicidal ideation in young adulthood, and these effects did not differ by gender. There were also no causal relations between adolescent depressive symptoms or suicidal ideation and casual sexual experience in young adulthood. Implications for ways to increase scientific rigor by using different methods (e.g., genetically informed analyses) are discussed.     

Aesthetic Capital: A Research Review on Beauty Perks and Penalties

The presence of aesthetically based cultural goods and their ever-increasing influence in modern society may pose a new conceptual opportunity to sociology. Specifically, how can the discipline forge an understanding of how value associated with beauty returns forms of individual wealth? A new term, i.e. aesthetic capital, might be an answer. Such a concept, we maintain, covers the privileges and wealth people receive from aesthetic traits, such as their face, hair, body, clothes, grooming habits and other markers of beauty. The purpose of our paper is to review the kinds of perks, and penalties, people receive from being deemed beautiful. Our review shows that visually appealing traits greatly impact our lives, in matters of modest importance (friend selection) to great importance (e.g. getting a job and career mobility). Thus, the promise of an aesthetic capital concept lies in enabling sociology to better understand inequality and the socially based forms of wealth available to individuals in modern society.     

Reassessing Differences in Work and Income in Cohabitation and Marriage

Are cohabiters different than married couples who cohabited before marriage? This study used the 2002 wave of the National Survey of Families and Households to determine how work behavior might differ for 4 relationship types: (a) cohabiters with uncertain marriage plans, (b) cohabiters with definite marriage plans, (c) premarital cohabiters who recently married, and (d) premarital cohabiters married 5 or more years (n = 638). The results are compared with differences found in overall comparisons of all cohabiters and married couples (N = 916) and were markedly different, indicating that overall comparisons do not adequately capture the range of behavior across cohabitation and marriage. Evidence of increased specialization was found in marriage, yet steep behavioral differences were not found between cohabiters with definite marriage plans and recently married couples but instead were associated with longevity in marriage. This implies that any possible causal effect of marriage on behavior may accrue with time spent married.     

Premarital Cohabitation and Direct Marriage in the United States: 1956–2015

Cohabitation rates and durations increased rapidly beginning in the late 1960s, and by 2011–2015, 70% of first marriages among women under age 36 began in premarital cohabitation lasting an average of 32?months before marriage. The National Survey of Families and Households (n?=?3,594) and the National Survey of Family Growth (n?=?9,420) are analyzed to estimate selection into direct marriage and premarital cohabitation from 1956–2015, and long- and short-term premarital cohabitations from 1971–2015. Early premarital cohabitors were more likely to be women of color and had the same education as direct marriers. Later cohorts of premarital cohabitors were less educated, from lower class backgrounds, more likely to have experienced a parental divorce/separation, less religious, and long-term premarital cohabitations were more common among women of color.     

Age at Coresidence,Premarital Cohabitation,and Marriage Dissolution: 1985–2009

Does the age at which premarital cohabitors moved in together explain why they have been found to have an increased risk of marital dissolution? Explanations for the increased risk of marriage dissolution among those who marry young center on marital role preparation; for premarital cohabitors, many, if not most, of these roles began at the onset of cohabitation, not marriage. Analyses of the 1995, 2002, and 2006–2010 waves of the National Survey of Family Growth (N = 7,037) revealed that age at coresidence explained a substantial portion of the higher marital dissolution risk of premarital cohabitors. In comparisons standardized by age at coresidence, the difference in risk of marital dissolution between premarital cohabitors and those who married without prior cohabitation (“direct marriers”) was much smaller than in comparisons standardized by age at marriage, and in some models this difference was not significant. Selection into direct marriage and premarital cohabitation was also examined.     

Sexual Self-Concept: Testing a Hypothetical Model for Men and Women

One theoretical concept receiving modest attention in contemporary sex research is the sexual self-concept (SSC). However, a lack of cohesion within this research has culminated in a collection of SSC models which overlap one another but which are not exactly the same. Therefore, a unified conceptual model of SSC needs to be established. In addition, little research has examined potential differences between genders in SSC, as most SSC research has focused on women. Using Buzwell and Rosenthal's 1996 Buzwell , S. , & Rosenthal , D. (1996). Constructing a sexual self: Adolescents’ sexual self-perceptions and sexual risk-taking. Journal of Research on Adolescence , 6, 489–513.[Web of Science ®] , [Google Scholar] sexual selves model as a theoretical basis, a six-factor higher-order latent SSC model was tested using confirmatory factor analysis. Lower-order factors for this model included multidimensional sexual self-esteem and sexual self-efficacy factors, as well as unidimensional arousal, anxiety, exploration, and commitment factors. A five-factor latent model (after removing the commitment and the resistance sexual self-efficacy factors) was the best-fitting model. This model was then tested for measurement and structural invariance between genders. Results indicated that while the measurement of SSC was similar between men and women, structural invariance did not hold, as men had a significantly higher latent SSC score compared to women. These findings have important implications for sexual self-concept research, as well as contributing to better understanding of human sexuality.     

Assessing Observer Effects on the Fidelity of Implementation of Functional Analysis Procedures

Instructing and training others to implement functional analysis (FA) procedures can be a cumbersome and time-consuming task. Students and practitioners are required to learn all of the various components to establish conditions and analyze results while also learning to conduct the sessions. The current study assessed the fidelity of individuals implementing FA conditions after observing and rating the fidelity of videos models, using a multiple-baseline design across FA conditions. Video models of each condition were provided throughout; however, participants were only asked to provide fidelity ratings for one video. Results demonstrated the intervention was successful in increasing participant performance above baseline levels for 16 of 17 participants, with 7 participants requiring an additional intervention in which they were asked to observe their own performance. Further research should evaluate the degree to which this procedure may effectively prepare individuals working with non-confederate children and carry over to other responses and settings.     

Dynamic Change Between Intimate Partner Violence and Contraceptive Use Over Time in Young Adult Men’s and Women’s Relationships

The negative association between intimate partner violence (IPV) and contraceptive use is well established, but much of this research treats the association as static (e.g., similar across all relationships over development or time). Such studies do not account for individual development of sexual and romantic relationship mental, social, and behavioral well-being, which relate to contraceptive use. These studies are also predominantly woman-focused; such work could be complemented by examining men’s associations. The current study examined how associations between sexual and physical IPV and consistent condom and birth control (BC) use changed across up to seven sequential relationships in young adulthood over a five-year period within a nationally representative sample. Results indicated that physical IPV–contraception associations were significant only across earliest or latest relationships. Sexual IPV–contraception associations were significant over more relationships but often changed in valence (negative to positive). There were few significant differences in these associations between men and women. Developmental context (e.g., prior relationship/IPV experience) may be important when considering IPV–contraception associations. In addition, although the IPV–contraception association does not appear to be a unique problem for women, research needs to explore how underlying mechanisms explaining this association may be a result of gendered and nongendered contexts.     

Thai Adolescents' Normative Beliefs of the Popularity of Smoking Among Peers,Adults, the Successful and Elite,and Parents

The purpose of this study was to assess the perceptions of Thailand adolescents regarding the prevalence of smoking, the popularity of smoking among successful/elite elements of society, and disapproval of smoking by friends and parents. These perceptions were analyzed in conjunction with actual smoking and smoking susceptibility rates among the subjects to determine whether beliefs and behaviors were associated with each other. This study was conducted among a school‐based sample of 2516 Chiang Mai, Thailand upper secondary and vocational students. Although perceived prevalence of smoking was not associated with smoking outcomes, perceived popularity of smoking among the successful and elite was associated with higher risk, and perceived disapproval by friends/parents was associated with lower risk. Youth smoking programs should consider assessing and taking these social normative factors into account when considering educational intervention strategies that aim to lower adolescent smoking rates.     

Output gap and non-linear economic convergence

We apply unit root tests in a multivariate TAR model with bootstrapping simulations to assess the influence of short-run economic conditions on long-run economic convergence and to extract economic policy implications. We use two different groups of countries whose members share important business cycle characteristics over the period 1953–2010. We show that per capita income convergence is not uniform along the business cycle and our analysis reveals that, apart from growth-led actions and structural reforms to avoid the evolution towards different national stationary states – especially within the euro zone – short-run stabilisation policies are vividly advised to guarantee long-run economic convergence.
