Longitudinal Consistency in Self-Reported Age of First Vaginal Intercourse among Young Adults

We examined consistency in self-reports of age at first vaginal sex among 9,399 male and female respondents who participated in Waves III and IV (separated by approximately seven years) of the National Longitudinal Study of Adolescent Health (Add Health). Respondents were coded as consistent if they reported an age at first vaginal intercourse at Wave IV that was within one year of the age they reported at Wave III. Sociodemographic, behavioral, and cognitive predictors of consistency were examined using bivariate and multivariate logistic regression. Overall, 85.43% of respondents were able to provide consistent reports. Among both males and females, consistency was associated with age, years since first vaginal intercourse, race/ethnicity, and lifetime number of other-sex partners in final multivariate models. Respondents who were older and had more recently had their first sexual experience were more likely to be consistent. For females only, those who reported a history of nonparental, physically forced sex were less likely to be consistent. Most young adults consistently report age at first vaginal intercourse, supporting the credibility of retrospective self-reports about salient sexual events such as timing of first vaginal intercourse.     

Correlates of Oral Sex and Vaginal Intercourse in Early and Middle Adolescence

This study examined whether a comprehensive set of psychosocial factors was equally predictive of both adolescent vaginal intercourse and oral sex among 1,105 adolescents aged 12–16. Logistic regressions were used to examine the relationships between parental communication, religiosity, bonding to school, heavy drinking, sex expectancies, normative beliefs, and both oral sex and vaginal intercourse. Age, gender, bonding to school, heavy drinking, and negative health expectancies predicted both oral sex and vaginal intercourse. Parental communication was associated with vaginal intercourse but not oral sex. Behavior‐specific normative beliefs were differentially associated with oral and vaginal sex.     

Recalling sexual behavior: A methodological analysis of memory recall bias via interview using the diary as the gold standard

This study examined the effect of time lag on the validity of retrospective self‐reports of sexual behavior. Seventy‐five heterosexual students (44 women, 31 men) made daily recordings of sexual behavior, condom use, and alcohol or substance use for 1 month. Ability of respondents to recall sexual behavior recorded during this period was assessed at 1, 2, and 3 months after diary completion using recall interviews (25 interviewed at each interval). For vaginal intercourse, total recall error was significantly greater at 3 months than at 1 month post‐diary. For all other variables assessed, the 2‐ and 3‐month time intervals did not produce significant increases in total recall error. Higher frequency of vaginal intercourse, orgasm, and alcohol use prior to sexual activity were associated with total recall error for some but not all behaviors and outcomes. The results provide a partial validation of the diary‐interview recall model as a method for studying recall error.     

Some aspects of prostitution

This study was based on data collected from 87 men during and immediately following participation in a counseling program aimed at assisting them to reduce sexual behaviors associated with high HIV risk. All the men reported having engaged in same‐gender anal or oral sex without condoms during the year prior to enrollment. Three‐month retrospective reports of sexual behavior, solicited just after participation, were compared with reports collected weekly during the same three‐month period. Accuracy of recall over an ensemble of 10 behavior items was quite low, with amount of error positively associated with behavior frequency. In general, exaggerated reports were associated with low‐frequency behavior and underreports with high‐frequency behavior. Because of observed differences in the average frequency of occurrence of the various specific types of sexual behavior, adjustment for event frequency was required to provide adequate analysis of between‐behavior differences in memory error. Estimated functional relationships between behavior frequency and average memory error illustrated that for sexual activity occurring between 1 and 20 times in the three‐month period, there was a significant association between the HTV‐risk level of a behavior and the average extent to which the behavior was forgotten (i.e., underreported). After event‐frequency adjustment, anal activity without condoms—the behavior believed to entail the highest level of risk for HIV transmission, and the behavior about which the counseling program provided the least ambiguous cues regarding risk—was associated with the greatest underreporting error, and the ensemble of unprotected behaviors (i.e., those unaccompanied by condom usage) involved significantly greater underreporting than did protected behaviors. Error rates over the ensemble of behaviors were strikingly low for zero‐frequency events, suggesting the utility of dichotomous ever/never measures in research evaluating activity levels and behavior change. Other analysis techniques for reducing potential recall bias, allowing finer evaluations of behavior frequency and change, were also discussed.     

Attitudes and use of pornography in the Norwegian population 2002

The purpose of this study was to describe and analyze use of pornographic material in a representative sample of adult Norwegians. The data collection was carried out by means of a standardized questionnaire administered via personal telephone interviews. Among the 90% of participants who reported ever having examined pornography, 76% reported examining a pornographic magazine, 67% had watched a pornographic film, and 24% had examined pornography on the Internet. Significant gender differences emerged in the reporting. The percentage of men and women who reported frequent use of pornography was small. We identified three dimensions of attitudes toward pornography: pornography as a means of sexual enhancement, pornography as a moral issue, and social climate. These attitude dimensions were included in path models as intermediating variables between demographic variables (age, gender, and level of education) and frequency of reading or watching pornographic materials. These models explained 36% of the variance in frequency of watching pornographic films, 35% of the variance in frequency of reading pornographic magazines, and 21% of the variance in frequency of watching pornography on the Internet.

Testing a theoretical model of adolescent sexual behavior among rural families in poverty

This was a study of 357 adolescents, aged 13 to 17 years, who resided in a family receiving AFDC in 10 rural counties in Arkansas. The study had a twofold purpose: 1) to examine what elements of social control, social learning, and strain theories predicted 3 measures of sexual behavior; and 2) to test an integrated theoretical model with 2-stage least squares regression to see if it fit the data on the 3 measures of sex. The measures of sexual behavior were frequency of sexual intercourse in the past year, number of sexual partners in the past year, and number of sexual partners in lifetime. Bivariate analyses revealed that the consistent predictors of the 3 measures of sex were age, gender, attachment to mother, beliefs, parental supervision and punishment, family and friend support, frustration, and use of rationalizations. The theoretical model that fit all measures of sex showed that bonding influences sexual behavior through frustration, and that age, gender and rationalizations directly impact behavior.     

Examining the influence of gender and sexual motivation in college hookups

ABSTRACT

Objective: Hooking up is common in college, and has been linked to heavy drinking. Hookups have positive as well as negative consequences, and thus the motivations for hooking up are complex. Yet, little research has focused on these motivations. The present study examined the role that gender and drinking patterns play in the relationship between sexual motivation and penetrative hookups. Participants: Heavy drinking college students (N = 396) completed online surveys between September/October 2009. Method: Sexual motivation, alcohol, and hooking up were assessed. Results: Enhancement motives and drinking frequency predicted more frequent oral and vaginal sex when hooking up, while peer and partner motives predicted anal sex. Men endorsed greater enhancement motives, peer motives, and hookup oral and vaginal sex. For men, coping motives predicted oral and vaginal sex and peer motives predicted anal sex. Conclusions: Results provide greater insight into the reasons why college students engage in penetrative hookups.     

"All my friends are doing it:" the impact of the perception of peer sexuality on adolescents' intent to have sex

The purpose of the authors in this study was to determine if the proportionality of peers who believe other youth are having oral sex or vaginal/anal intercourse influence the youth's intention to also have oral sex or vaginal/anal intercourse in the next three months. The results supported the hypothesis that the proportionality of perceiving one's peers as sexually active was correlated with one's intent to have oral sex in the next three months (r = .34 and .39, p < .01) and one's intent to have vaginal or anal sex within the next three months (r = .51 and r = .65, p < .01). Approximately 50% of youth who intent to have oral sex are also likely to have vaginal/anal sex. The results were not moderated by age, gender, or Hispanic/White status, but were moderated by being in a special/committed relationship.     

Sex, age, season, and habitual physical activity of older Japanese: the Nakanojo study

The interactions of sex, age, season, and habitual physical activity were examined in 41 male and 54 female Japanese age 65-83 yr, using a pedometer/accelerometer that determined step counts and amounts of physical activity (<3 and >3 metabolic equivalents [METs]) throughout each 24-hr period for an entire year. All 3 measures were greater in men than in women. In women, age was negatively correlated with step count and activity <3 METs, but in men, it was correlated with step count and activity >3 METs. Irrespective of sex or age, all 3 activity variables were low in the winter, peaking in spring or autumn. In the summer, step counts matched the annual average, but durations of activity <3 and >3 METs were, respectively, longer and shorter than in other seasons. These findings have practical implications for those promoting physical activity for older adults.     

Fecal incontinence during intercourse associated with a rectocele: A case Report

We present results of the first longitudinal study of long‐term outcome correlates of sexual experiences in early childhood (“sex play”). Two hundred children participated in the UCLA Family Lifestyles Project (FLS), beginning at birth to the current wave of data collection at ages 17–18. For most of the current analyses, data were complete for 96 of the young men and 88 of the young women. Participants were assessed on a wide range of adjustment variables devised for the FLS and the UCLA Adolescent Growth Study. Participation in early childhood sex play was determined by parent self‐reports at child's age three and age six. Forty‐eight percent of children were reported to have engaged in interactive sex play prior to age six. Using socioeconomic status, sex of participant, family attitudes toward sexuality, and family type (conventional two‐parent versus nonconventional) as controls, no significant long‐term associations were found between exposure to sex play and adjustment at ages 17–18. Sexual liberalism/conservativism in family of origin was significantly associated with sexual liberalism I conservativism at ages 17–18. These results converge on earlier cross‐sectional retrospective work, suggesting that the experience of childhood sex play in itself is unrelated to long‐term adjustment.     

Recalling sexual behavior: a methodological analysis of memory recall bias via interview using the diary as the gold standard

This study examined the effect of time lag on the validity of retrospective self-reports of sexual behavior. Seventy-five heterosexual students (44 women, 31 men) made daily recordings of sexual behavior, condom use, and alcohol or substance use for 1 month. Ability of respondents to recall sexual behavior recorded during this period was assessed at 1, 2, and 3 months after diary completion using recall interviews (25 interviewed at each interval). For vaginal intercourse, total recall error was significantly greater at 3 months than at 1 month post-diary. For all other variables assessed, the 2- and 3-month time intervals did not produce significant increase in total recall error. Higher frequency of vaginal intercourse, orgasm, and alcohol use prior to sexual activity were associated with total recall error for some but not all behaviors and outcomes. The results provide a partial validation of the diary-interview recall model as a method for studying recall error.     

Examining residence status as a risk factor for health risk behaviors among college students

Objective: The current study is aimed to evaluate college student residence as a unique risk factor for a range of negative health behaviors. Participants: We examined data from 63,555 students (66% females) from 157 campuses who completed the National College Health Assessment Survey in Spring 2011. Methods: Participants answered questions about the frequency of recent use of alcohol, tobacco, marijuana, and illicit drugs, as well as sexual risk behavior in the last 30 days. Sexual risk behaviors were operationalized as having unprotected vaginal sex (yes/no) and the number of sexual partners. Results: Logistic regression analyses revealed that living off-campus is a unique predictor of alcohol, tobacco, marijuana, and illicit drug use, as well as engaging in unprotected sex and a greater number of sexual partners (all ps <. 01). Conclusions: Students living off-campus exhibit more substance use and sexual risk behaviors than students living on-campus, independent of gender, age, or race.     

Sexual Behaviors in Mexico: The Role of Values and Gender Across Adolescence

Adolescent sexuality research has expanded to include noncoital behaviors, but there is limited knowledge about individual factors such as cultural values associated with these sexual behaviors outside of industrialized nations. Thus, we examined associations between Latino values (familism, sexual guilt, and importance of female virginity) and three sexual behaviors (making out, oral sex, and vaginal sex), among adolescents ages 12–19 (53% female) in Mexico. Findings indicate that sexual guilt and importance of female virginity were consistently associated with all sexual behaviors. Some associations differed by gender and school level. For instance, sexual guilt was a better predictor of high school girls’ oral and vaginal sex. This study expands our understanding of adolescent sexuality in Mexico.     

Men Sexually Interested in Transwomen (MSTW): Gendered Embodiment and the Construction of Sexual Desire

Unreliable self‐reporting of sexual behavior has been suggested as a major cause of variance in survey research. In addition, differing gender‐related biases are thought to account for discrepancies in reports of oral and anal sex. Insufficient attention, however, has been given to assessing the reliability of the sexual partner's reports. Data obtained from 70 couples concerning 68 sexual behaviors was reviewed. Four different reliability indices yielded moderate to substantial agreement. These included a simple percentage criterion of 87%, a Kappa of .67, and conditional probabilities of .77 and.91. Previously reported discrepancies in the reporting of oral and anal sex were not found. Kappa was found to be superior to simple percentage agreement, but produced overly conservative reliability estimates when derived from behaviors that occur at either high or low base‐rates. The two conditional probability indices are proposed for use in conjunction with Kappa to evaluate the reliability of partner data.     

Attitudes toward wife rape: effects of social background and victim status

The current literature on wife rape is minimal compared to the published research in areas such as wife battering or date rape, and most of the existent work on attitudes toward wife rape is dated and/or focuses on limited samples (i.e., college populations). Using data from a nationally representative telephone survey, this study examined national attitudes toward wife rape using the following measures: perceptions of the occurrence of wife rape, perceptions of the frequency of wife rape, and perceptions of three rape scenarios. Respondent sex, education, age, race, and female victim status were predictors. Findings reveal that older, non-white respondents were less likely to believe wife rape occurs. Males and the more educated were less likely to believe it occurs frequently. Older and less educated respondents were less likely to believe forced sex scenarios between a husband and wife constitute wife rape. Among women, non-victims of forced sex were significantly less likely than current victims to believe that wife rape occurs.     

Using the Experience Sampling Method to Study Sexual Risk Behavior among Men Who Have Sex With Men (MSM)

Toward the goal of advancing understanding of rates of HIV transmission among men who have sex with men (MSM) populations, this article provides preliminary data on the use of the experience sampling method (ESM) in a sample of 165 MSM. Participants completed 6 weeks of experience sampling in two 3-week measurement bursts with a 3-week rest interval. Criterion validity of the random and retrospective daily assessments was supported by expected within-person correlations between sexual risk behavior and sexual arousal. Participants reported some sexual activity with a male partner on 18.62% of the days, condomless anal sex (CAS) on 6.52% of days, and not using condoms on 66.56% of days they had anal sex. Over half of the variability in CAS was at the within-person level, which suggests the significance of time varying contextual factors. Finally, CAS reports were relatively stable across the study, suggesting a lack of reactivity to the self-monitoring.     

Methodological Comparisons Between CATI Event History Calendar and Standardized Conventional Questionnaire Instruments

Six hundred and twenty-six participants from the Panel Studyof Income Dynamics (PSID) were interviewed via telephone retrospectivelyabout life course events by either computer-assisted (CATI)event history calendar (EHC) or standardized CATI conventionalquestionnaire (CQ) methods, randomly assigned. Experimentalretrospective reports, for a reference period up to 30 years,were validated against reports provided annually from the PSIDcore interviews. Data quality outcome measures included variablesassociated with marriage, cohabitation, employment, unemployment,residential changes, and cigarette smoking. The EHC providedhigher quality retrospective reports for cohabitation, employment,unemployment, and smoking histories; the CQ provided betterdata quality for marriage history, although what variable wasbeing measured, instead of which method was being used, hadthe biggest impact on differences in data quality. Both EHCand CQ interviews lasted on average around one hour, with theEHC interviews being on average 10 percent longer. Interviewerspreferred the EHC interviews. In both EHC and CQ conditions,respondents generally enjoyed the interviews, and did not findquestions difficult. The costs and benefits of both EHC andCQ methods in the collection of life course retrospective reportsare discussed. Received for publication December 19, 2005. Revision received September 25, 2007.
