Objective: The objective of this study was to investigate the readmission rate, and the level of patient disturbance and community care associated with readmission following Community Treatment Orders (CTOs) in New South Wales, Australia., Method: The readmission rates of all patients given CTOs within a 4-year period and a matched comparison group were investigated. The following factors were compared before, during and following a CTO: medication non-compliance, number of clinical services and duration of disturbed behaviour preceding hospitalisations., Results: Of 123 patients on CTOs (mean length, 288 days; SD, 210 days), 38 were readmitted during the CTO, the majority in the first 3 months and a further 21 patients were readmitted following termination of the CTO. Evidence of lower severity of illness in the comparison patients prevented meaningful evaluation of the readmission rates of the two groups. While on CTOs, patients receiving depot medications showed high compliance and a significantly reduced readmission rate compared with that of patients receiving oral medications. In the 2 months prior to hospitalisations during CTOs, compared with those before or after CTOs, patients received more frequent consultations and showed a shorter duration of medication non-compliance and disturbed behaviour. The level of services in the 3 months following discharge were comparable for patients on CTOs and the comparison group., Conclusions: CTOs may reduce rehospitalisations by use of depot medication. Earlier and possibly more frequent readmissions in the CTO group shortened the disturbance associated with illness recurrence. It would appear that to establish a control group with equivalent severity of disorder necessary to evaluate the impact of CTOs requires a random allocation design.

Masculinity and femininity have been studied by self-ratings in independent areas of research: one investigating personality traits considered masculine (M) or feminine (F); the other, behaviours statistically more common in one than in the other sex (sex-linked behaviours). The two approaches were compared for the first time in the present study of 66 male and 51 female medical students. Consistent with previous findings using the second approach, male but not female subjects' opposite sex-linked "sissy" and "tomboyish" behaviours correlated significantly with their reported ratio of homosexual to heterosexual feelings (Ho/Het). Ho/Het did not correlate with either sex's M and F scores, but high M scores in women correlated strongly with several "tomboyish" behaviours. As "tomboyish" behaviours are shown more strongly by women exposed prenatally to increased levels of opposite sex hormones compared to controls, the findings have implications for the biological theory attributing Ho/Het to such prenatal hormonal exposure.

Whether homosexual feelings are distributed categorically or dimensionally remains controversial. In an earlier series of studies, medical students anonymously reported a dimensional distribution of homosexual feelings, the ratio of homosexual to heterosexual feelings in men correlating with opposite sex-linked behaviors in childhood and adolescence, and, in both sexes, with current degree of opposite sex identity. Prevalence of homosexual feelings was markedly higher than that found in nonanonymous studies. In the present investigation, a study of male twins allowed investigation of the findings in 411 educationally more representative subjects. Awareness of some homosexual feelings was reported in adolescence by 20% and currently by 12%. As with medical students, the majority of those who reported some homosexual feelings were predominantly heterosexual, which could be considered to indicate such feelings were distributed dimensionally. Correlations between degree of homosexual feelings and avoidance of contact sport in childhood and adolescence, current wish to be of the opposite sex, and opposite sex identity remained present when subjects with equally bisexual and predominantly homosexual feelings were excluded from analysis. The finding that the majority of men with homosexual feelings are predominantly heterosexual renders implausible the theory that homosexual feelings result from fear of heterosexuality.

Sixty-six male and 51 female second year medical students anonymously completed the Sexual Experiences Survey (SES) and the Attraction to Sexual Aggression (ASA) Scale, both modified so that women could report behaviours in which they were aggressors, and men, behaviours in which they were victims. Men's aggression scores on the two scales were significantly correlated. As expected, more men than women reported both the likelihood and the experience of being sexual aggressors, although 6% of women reported being so aroused they couldn't stop when their partner didn't want intercourse and 13% of men reported having intercourse against their will. In men sexually coercive behaviours correlated positively with the masculinity scale of the Bem Sex Role Inventory. Fewer female medical students reported experiencing sexually aggressive behaviours compared to US or New Zealand university students; however, the percentage of male students who reported using or threatening to use physical force was in the same range as that of US students. Significant attention to the issue of sexual coercion would appear necessary in the education of medical students.

When relationships are found between parents' and children's behaviors it is usually assumed the parents' behaviors produced those of the children. Forty-four young adult males and 36 young adult females reported the degree to which they showed various sex-linked behaviors and feelings of same versus opposite sex identity in childhood, and adolescence, and currently. These behaviors accounted for up to 57% of the variance of measures of the quality of relationships with parents. In men, opposite-sex-linked behaviors and identity correlated most strongly with current negative parental and particularly paternal relationships. They also correlated strongly with negative paternal relationships in childhood. Some sex-linked behaviors and sex identity items in men correlated positively with maternal overprotection in childhood and adolescence. Correlations between women's sex-linked behaviors and sexual identity items and their parental relationships were weaker but more consistently negative. As in men, opposite-sex-linked behaviors and identity in women correlated most strongly with current negative paternal relationships. The pattern of the associations and the finding that many opposite-sex-linked behaviors in subjects' childhood correlated most strongly with negative parental relationships in early adult life suggest that the parents' feelings could be partly a response to, rather than totally causal of, the subjects' sex-linked behaviors.

The treatment programme for sex offenders at the Prince of Wales Hospital, Sydney, is described. Penile circumference assessment is not used as there is no evidence it provides a valid measure of individuals' paedophile or rapist tendencies. Sex offenders' self-reports remain the major source of information in their assessment. The development of the two major techniques used--imaginal desensitization and short-term medroxyprogesterone--is outlined. About 80% of subjects can be expected to show a good response to one or other of these therapies. Of those who do not, most respond to the alternative or aversive therapy. Adolescent offenders appear to require more intensive treatment. Results appear comparable with those of more intensive programmes in use overseas.
