Get High and Get Stupid: The Effect of Alcohol and Marijuana Use on Teen Sexual Behavior

Numerous studies have documented a strong correlation between substance use and teen sexual behavior, and this empirical relationship has given rise to a widespread belief that substance use causes teens to engage in risky sex. This causal link is often used by advocates to justify policies targeted at reducing substance use. Here, we argue that previous research has not produced sufficient evidence to substantiate a causal relationship between substance use and teen sexual behavior. Accordingly, we attempt to estimate causal effects using two complementary research approaches. Our findings suggest that substance use is not causally related to teen sexual behavior, although we cannot definitively rule out that possibility.Research for this paper was supported by grant number 5 R01 DA12692 from the National Institute on Drug Abuse to the National Bureau of Economic Research.

Age, ethnicity, and use of complementary and alternative medicine in health self-management

Drawing on models of health self-management, we develop hypotheses that age and ethnicity will modify associations among indicators ofpoor health and use of complementary and alternative medicine. These hypotheses are evaluated using the 2002 National Health Interview Survey with the Alternative Health Supplement. Results produced partial support for hypotheses that the effects of ailments on use of complementary and alternative medicine differ by age. Results suggest that ailments such as bodily pain, chronic conditions, and functional impairment are associated with use of complementary and alternative medicine among midlife and younger adults, but these associations are generally attenuated among older adults. Hypothesized ethnic differences received weak support. These findings suggest that different interpretations of ailments and appropriate responses may explain why complementary and alternative medicine is used by fewer older adults. The results also highlight the significance of social and cultural factors in understanding patterns of complementary and alternative medicine use in the adult population.     

Fostering healthy futures: an innovative preventive intervention for preadolescent youth in out-of-home care

Although we have not yet demonstrated empirically that the FHF program is effective in addressing mental health, behavioral, and academic issues among preadolescent youth placed in foster care, we believe we have a very promising model. We have successfully negotiated many challenges of conducting a RCT within a child welfare setting, in large part because of the collaboration and support of our community partners. The ultimate goal of this research is to develop more efficacious interventions, thereby reducing adverse life-course outcomes and promoting healthy futures, not only for youth in out-of-home care, but for all youth at risk.     

The devil is in the details: examining the evidence for "proven" school-based drug abuse prevention programs

In an effort to promote evidence-based practice, government officials, researchers, and program developers have developed lists of model programs in the prevention field. This article reviews the evidence used by seven best-practice lists to select five model prevention programs. The authors' examination of this research raises questions about the process used to identify and publicize programs as successful. They found limited evidence showing substantial impact on drug use behavior at posttest, with very few studies showing substantial impact at longer follow-ups. The authors advocate additional long-term follow-up studies and conclude by suggesting changes in the procedures for developing best-practice lists.     

Vaginal Dryness and Beyond: The Sexual Health Needs of Women Diagnosed With Metastatic Breast Cancer

While research on the sexual health of women with early stage cancer has grown extensively over the past decade, markedly less information is available to support the sexual health needs of women diagnosed with advanced breast cancer. Semistructured interviews were conducted with 32 women diagnosed with metastatic breast cancer (ages 35 to 77) about questions they had concerning their sexual health and intimate relationships. All participants were recruited from a comprehensive cancer center at a large Midwestern university. Three themes were examined: the role of sexual activity and intimate touch in participants' lives, unmet information needs about sexual health, and communication with medical providers about sexual concerns. Findings indicated that sexual activities with partners were important; however, participants worried about their own physical limitations and reported frequent physical (e.g., bone pains) and vaginal pain associated with intercourse. When women raised concerns about these issues in clinical settings, medical providers often focused exclusively on vaginal lubricants, which did not address the entirety of women's problems or concerns. In addition, women diagnosed with metastatic breast cancer reported needing additional resources about specialized vaginal lubricants, nonpenetrative and nongenitally focused sex, and sexual positions that did not compromise their physical health yet still provided pleasure.     

The Quality of Spontaneous Movements of Preterm Infants: Associations with the Quality of Mother–Infant Interaction

The assessment of the quality of infants’ spontaneous movements is a diagnostic tool for the young nervous system. We examined whether it relates to the quality of the interactions between infants born preterm and their mothers. Thirty‐nine healthy infants born preterm (M_{age in weeks} = 14.59, SD = 2.21; 38.46% female) and their mothers participated in the study. Infants’ quality of spontaneous movements was assessed using the General Movement Assessment according to Prechtl (Prechtl, Early Human Development 1990, 23, 151). A new measurement was employed to evaluate the following aspects of the mother–infant interaction: maternal sensitivity in the motor modality (i.e., when touching, picking up, holding, and putting down the infant), maternal sensitivity in the modalities of vocalization and eye contact, and infants’ positive engagement. Several aspects of infants’ quality of movements were associated with maternal sensitivity in the motor modality and infants’ positive engagement, but not with maternal sensitivity in the modalities of vocalization and eye contact. These findings suggest that the quality of infants’ spontaneous movements may explain some of the variability in the interactions between infants born preterm and their mothers. The results also highlight the importance of differentiating between the modalities of mothers’ behavior when assessing their sensitivity. Implications for research and practice with families of preterm infants are discussed.     

Iranian College Students’ Attitudes Toward Premarital Sex,Marriage, and Family Before and After the Islamic Revolution

ABSTRACT. Objectives: The purpose of this study was to examine Iranian college students’ attitudes toward premarital sex and marriage before and after the Islamic Revolution. Methods: Responses to a survey from 526 students at University of Shiraz in 2011 were compared to those from another study of 392 students from the same university who completed the same survey in 1977 (2 years before the Islamic Revolution). Results: No substantial changes were observed to indicate that college students adopted theocratic views on premarital sex and marriage after the Islamic Revolution. Conclusions: The Islamic regime's efforts to cultivate conservative attitudes toward sexuality and marriage have not achieved their goals.     

Cultural constructions of the concept of household in sample surveys

We analyse the use of the concept of household in sample surveys, with evidence drawn from a review of survey definitions, a series of in-depth interviews with data producers and users, and a systematic study of recent literature. We consider the place of the concept within the discipline of demography, and demonstrate how its definition and use interact with cultural values and core concepts integral to the discipline. Focusing on Tanzania as a case study, we examine the diversity of factors that influence the construction of household-level data from cross-sectional household surveys. Throughout the survey process, contrasting interpretations of the meaning of household and different motivations for using specific definitions of the term interact. This generates data and outputs with potential for undercounting, bias, and misrepresentations, with adverse effects on the quality of data used for monitoring development indicators. Some ways of improving data collection on households are proposed.     

Individuals' beliefs about the etiology of same-sex sexual orientation

We examined the relationships between beliefs about the etiology of having a same-sex sexual orientation, sexual prejudice, and support for gay-relevant legislation using the justification-suppression model of prejudice as our theoretical foundation. Results indicated that more belief that a same-sex sexual orientation was due to nurture factors predicted less support for gay-relevant legislation, and that this relationship was mediated by levels of sexual prejudice. The opposite pattern was found for belief that a same-sex sexual orientation was due to nature factors. This suggests that beliefs about the etiology of sexual orientation may serve as justification (or suppression) factors in the expression of prejudice toward gay men and lesbians.
