Dimensions of subjective female orgasmic responsiveness.

Results of recent psychological research have been at odds with the major physiological evidence on the nature of female orgasmic responsiveness. Although female orgasm appears to be a single process physiologically, subjective reports by women indicate that individual differences in their experience is multidimensional. The basis for the discrepant findings is analyzed via two studies of reported orgasmic experiences in women. One sample of 115 sexually experienced women yielded data that replicated the finding that coital and masturbatory orgasmic responsiveness can be statistically distinguished and independently assessed, thus indicating that sample selection associated with prior research could not explain the result. A separate sample of 101 sexually experienced women were given an instrument that assessed coital responsiveness but differentiated masturbatory responsiveness into dimensions associated with masturbation when alone and with a partner without intercourse. A confirmatory factor analysis substantiated the existence of the three dimensions of female orgasm. However, female orgasmic responsiveness was highly correlated across the three dimensions so that it was possible to isolate a large second-order factor of general orgasmic responsiveness that is consistent with most of the physiological evidence on the unitary nature of orgasm. Correlates of the orgasm scales with background data revealed some discriminant validity for the three dimensions of responsiveness.

Childhood play activities of male and female homosexuals and heterosexuals.

This study examined the differences in childhood play behavior reported by adult male homosexuals (N = 198) and heterosexuals (N = 198) and those reported by female homosexuals (N = 198) and heterosexuals (N = 198). Two checklists with a total of 58 sports, games, and play activities were assembled: one for ages 5--8 and the other for ages 9--13. These were administered to the four samples. Monotonicity analysis (a type of factor analysis) revealed four scales within each checklist that were statistically reliable in each of the four samples. Scale and item mean comparisons revealed large significant differences between heterosexual males and females, male homosexuals and heterosexuals, and female homosexuals and heterosexuals. A majority of homosexuals reported significant degrees of cross-sex behavior in childhood play. Favorite play activities, age trends, play-related attitudes, and parent-child interactions were also examined.

Assessment of personality and demographic aspects of cohabitation and marital success.

The outcomes of 68 marriages of four-year duration were compared on the basis of whether the partners had or had not cohabited premaritally. Background characteristics and personality data were assessed on those couples when there were newly married, and they were followed-up four years later to determine their current marital status, level of satisfaction, difficulty with various problem areas and the number of children born to them. No reliable differences on marital satisfaction or divorce rates between premarital cohabitors and noncohabitors were found. Cohabitors who divorced did so while reporting less marital distress than noncohabitors who divorced. Premarital cohabitors had significantly fewer children than noncohabitors. Degree of difficulty experienced on various problem areas differed between the groups. Certain personality and background variables predicted marital success differently for the two groups. Using the same selected set of six predictor variables, multiple regression equations were generated for cohabitors and noncohabitors. The cohabitors equation (R2 = .56) predicted marital success significantly more effectively than the noncohabitors equation (R2 = .28), When comparing the tri-weight vectors for these two equations, none of the predictor variables had the same influence in both groups. Theoretical implications of the findings were discussed.

Predictors of polydrug use among four ethnic groups: a 12-year longitudinal study.

We examined adolescent risk and protective constructs associated with adult polydrug use among four ethnic groups. Both mean and relational differences among the constructs were examined by ethnic group. Teenage polydrug use was a significant predictor of adult polydrug use for Caucasians, African-Americans, and Latinos. Although this relationship was not evident for Asians, teenage alcohol use increased adult cigarette use, and early religiosity increased adult alcohol use. Early parental support/bonding predicted less adult Polydrug Use for Caucasians. For Latinos, general social conformity and low liberalism decreased cigarette use as an adult. In general, the implications of the results are that prevention strategies should emphasize the reduction of teenage drug use to decrease adult polydrug use among Caucasians, Latinos, and African-Americans. Future research should examine other possible risk and protective conditions related to adult polydrug use among diverse populations.
