This study sought to desribe and compare commitment structures among lesbian and gay male living-together relationships, and to develop an instrument which would measure different dimensions of commitment among gay dyads without some heterosexual biases inherent in traditional measures of interpersonal commitment. Questionnaire data collected from 32 lesbians and 50 gay males who had lived together for at least six months were factor analyzed, yielding three factors: (1) intradyadic commitment, (2) extradyadic commitment, and (3) commitment-as-trust. On all three of these indices the lesbians scored somewhat higher than did the gay males, but in fact there were surprisingly few significant differences between the gay men and the lesbians. Suggestions in the data that lesbians report somewhat less social supports and are more concerned with couple boundary maintenance, whereas gay males report somewhat more jealousy and dependency, are discussed in terms of their implications for such relationships. 相似文献

We conducted an exploratory study comparing 47 college-aged women reporting depressive symptoms but not receiving antidepressant medication to 47 age-matched controls. We examined various dimensions of sexual functioning, including sexual desire, arousal, orgasm, pain, pleasure, and satisfaction. The women with depressive symptoms reported more inhibited sexual arousal, more inhibited orgasm, more sexual pain problems, and less sexual satisfaction and pleasure than control participants. Novel to this study, the women with depressive symptoms reported greater desire for sexual activity alone (masturbation) than the nondepressed women. The findings are discussed in terms of primary reinforcers and depressive symptomology. 相似文献

Although many researchers have explored the topic of dating violence, limited attention has been paid to female perpetrators. Very little research has examined variables that facilitate aggression for females in dating relationships. In an effort to investigate distinct types of violent behavior, the present study separated females who experience dating violence into three categories (bi-directional aggression, perpetrator-only, and victim-only) and compared them with a control group not previously exposed to interpersonal violence. The purpose of this study was to examine variables that discriminate violent females from non-violent females. Variables that were hypothesized to be associated with aggressive behavior and investigated in the current study were interparental aggression, self-esteem, love attitudes, and alcohol use. Three hundred female college students responded to multiple self-report questionnaires examining psychological correlates of dating violence. Females in the bi-directional aggression group were more likely to have witnessed their father abuse their mother and scored significantly lower on a measure of self-esteem than non-violent controls. Females in the control group demonstrated higher scores on a measure of mature and selfless love style than did the victim or perpetrator-only participants. There were no significant group differences regarding general alcohol consumption. Implications for prevention and intervention are presented and discussed. 相似文献

1. Women's adverse experiences as patients in secure and other mental health services appear to reflect sexism in wider social and historical contexts. 2. A Women's Service Development Group in a medium secure unit in the United Kingdom has made improvements in services for female patients, including an independent advocacy and befriending service, a Well-Woman Clinic, and other gender-sensitive activities. 3. In general, services were evaluated positively by women. Some dissatisfaction primarily was related to activities, issues concerning seclusion, and the lack of a day area for women only. 4. Women had mixed views about their contact with male staff and patients. Because of this, policies and services in this and related areas should account for individual needs. 相似文献

In robust parameter design, variance effects and mean effects in a factorial experiment are modelled simultaneously. If variance effects are present in a model, correlations are induced among the naive estimators of the mean effects. A simple normal quantile plot of the mean effects may be misleading because the mean effects are no longer iid under the null hypothesis that they are zero. Adjusted quantiles are computed for the case when one variance effect is significant and examples of 8-run and 16-run fractional factorial designs are examined in detail. We find that the usual normal quantiles are similar to adjusted quantiles for all but the largest and smallest ordered effects for which they are conservative. Graphically, the qualitative difference between the two sets of quantiles is negligible (even in the presence of large variance effects) and we conclude that normal probability plots are robust in the presence of variance effects. 相似文献

The study describes an evaluation of a 48‐week physical activity and nutritional education programme for overweight/obese school‐age children using quantitative and qualitative methods. The majority of participants were obese or severely obese when enrolled, and while some improvements in body mass index, self‐esteem and engagement in a range of physical activities were noted, difficulties in evaluating a complex community‐based intervention were highlighted. Children, parents and health professionals described a range of benefits from attending the programme but more intensive services are likely to be needed for the most seriously obese children and for those families resisting intervention. 相似文献

One of the main advantages of factorial experiments is the information that they can offer on interactions. When there are many factors to be studied, some or all of this information is often sacrificed to keep the size of an experiment economically feasible. Two strategies for group screening are presented for a large number of factors, over two stages of experimentation, with particular emphasis on the detection of interactions. One approach estimates only main effects at the first stage (classical group screening), whereas the other new method (interaction group screening) estimates both main effects and key two-factor interactions at the first stage. Three criteria are used to guide the choice of screening technique, and also the size of the groups of factors for study in the first-stage experiment. The criteria seek to minimize the expected total number of observations in the experiment, the probability that the size of the experiment exceeds a prespecified target and the proportion of active individual factorial effects which are not detected. To implement these criteria, results are derived on the relationship between the grouped and individual factorial effects, and the probability distributions of the numbers of grouped factors whose main effects or interactions are declared active at the first stage. Examples are used to illustrate the methodology, and some issues and open questions for the practical implementation of the results are discussed. 相似文献

The cognitive and behavioral status at age six years of 185 children of adolescent mothers (60.5% boys) were assessed using the mother (CBCL) and teacher (TRF) report forms of the Child Behavior Checklist and the Bracken Basic Concepts Scale. There was evidence for impairment in all areas of functioning. More than half of the sample exceeded the borderline clinical cutoff (T = 60) on either the CBCL or TRF Total Problem score, and nearly half the sample had Bracken scores that were more than 1 SD below the normative mean. Only 26.9% of the children were in the normal range on all three measures. These results are discussed in terms of implications for social work practice with children and adolescent mother families. 相似文献
