Premarital Sexual Intercourse: A Test of the Effects of Peer Group, Religiosity, and Sexual Guilt

Abstract: Previous research findings have been inconsistent concerning the influence on a person's sexual behavior of the peer group's sexual behavior and approval. Therefore, in this paper the relative importance of one's closest, friends' sexual behavior, their perceived approval for engaging in premarital coitus. age, sex guilt, and conventional religiosity were examined. Respondents were 467 dormitory students from a large mid‐Atlantic university. Results of separate path analyses for men and women showed that the greater the number of close friends thought to be nonvirgins, the greater the likelihood the man was also nonvirgin. Anticipated approval from close friends was not associated with a man being a nonvirgin. For women, both the sexual behavior and the expected degree of approval from close friends was associated with a woman being a nonvirgin. For both sexes, sex guilt was negatively associated with being a nonvirgin, whereas the respondent's age and degree of conventional religiosity were not ...

How Large Should the Sample be? A Question with no Simple Answer? or...

Abstract: A recurring problem in behavioral science research is that of determining the appropriate sample size before conducting a research investigation. The more common approaches to this problem have been to apply indiscriminantly the formulae used in survey research without considering the factors necessary for using these formulae. The most important of these factors is the Effect Size. In this paper, tables for the appropriate sample sizes are presented and discussed in the context that the determination of the Effect Size must precede the determination of the sample size.

How Large Should the Sample Be? Part II—The One-Sample Case for Survey Research:

Abstract: In a previous article, the authors discuss the importance of the effect size and the Type II error as factors in determining the sample size (Hinkle and Oliver, 1983). Tables were developed and pre...

Adlerian parent education: Changes in parents' attitudes and behaviors, and children's self-esteem

Abstract: The Adlerian approach to family education is receiving increasing attention. The Adlerian philosophy reflects a systematic approach with special emphasis upon the family constellation. The family is viewed as a total unit, and the individual needs of the family members are seen as family group needs with each meinber attempting to establish his/her place within the family structure. The purpose of the present study was twofold: first, to determine the reliability and validity of three measurement scales appropriate for assessing the effects of family education programs, and second, to determine the effects of a family education program using the Adlerian approach. The data indicated high reliability for the scales and the beneficial aspects of the family education program.

Gender differences in sexuality: a meta-analysis.

Abstract: This meta-analysis surveyed 177 usable sources that reported data on gender differences on 21 different measures of sexual attitudes and behaviors. The largest gender difference was in incidence of masturbation: Men had the greater incidence (d = .96). There was also a large gender difference in attitudes toward casual sex: Males had considerably more permissive attitudes (d = .81). There were no gender differences in attitudes toward homosexuality or in sexual satisfaction. Most other gender differences were in the small-to-moderate range. Gender differences narrowed from the 1960s to the 1980s for many variables. Chodorow's neoanalytic theory, sociobiology, social learning theory, social role theory, and script theory are discussed in relation to these findings.

Ethnic and American Identity as Predictors of Self-Esteem Among African American, Latino, and White Adolescents

Abstract: In order to examine ethnic and American identity as predictors of self-esteem among adolescents, we surveyed 669 American-born high school students (372 Latinos, 232 African Americans, and 65 Whites). Participants completed measures of self-esteem, ethnic identity, American identity, attitudes toward other groups, and demographic variables. Multiple regression analyses of self-esteem were carried out separately for each ethnic group, using ethnic and American identity, other-group attitudes, gender, age, socioeconomic status, and grade point average as predictors. Results indicated that for all groups ethnic identity was a significant predictor of self-esteem. For the White students only, American identity was a strong predictor of self-esteem and was highly correlated with ethnic identity. Other predictors varied across ethnic groups. Although ethnic identity was a significant predictor of self-esteem, it accounted for a relatively small proportion of the variance, suggesting the importance of other influences on self-esteem.

Gender differences in erotic plasticity: the female sex drive as socially flexible and responsive

Abstract: Responding to controversies about the balance between nature and culture in determining human sexuality, the author proposes that the female sex drive is more malleable than the male in response to sociocultural and situational factors. A large assortment of evidence supports 3 predictions based on the hypothesis of female erotic plasticity: (a) Individual women will exhibit more variation across time than men in sexual behavior, (b) female sexuality will exhibit larger effects than male in response to most specific sociocultural variables, and (c) sexual attitude-behavior consistency will be lower for women than men. Several possible explanations for female erotic plasticity are reviewed, including adaptation to superior male political and physical power, the centrality of female change (from no to yes) as a prerequisite for intercourse, and the idea that women have a milder sex drive than men.

Race and self-esteem: meta-analyses comparing whites, blacks, Hispanics, Asians, and American Indians and comment on Gray-Little and Hafdahl (2000).

Abstract: These meta-analyses examine race differences in self-esteem among 712 datapoints. Blacks scored higher than Whites on self-esteem measures (d = 0.19), but Whites scored higher than other racial minority groups, including Hispanics (d = -0.09), Asians (d = -0.30), and American Indians (d = -0.21). Most of these differences were smallest in childhood and grew larger with age. Blacks' self-esteem increased over time relative to Whites', with the Black advantage not appearing until the 1980s. Black and Hispanic samples scored higher on measures without an academic self-esteem subscale. Relative to Whites, minority males had lower self-esteem than did minority females, and Black and Hispanic self-esteem was higher in groups with high socioeconomic status. The results are most consistent with a cultural interpretation of racial differences in self-esteem.
