Psychophysiological and endocrine responses to sexual arousal in women.

The unexplored possibility that a sexually induced endocrine response might prime further sexual arousal in women guided the current investigation. Healthy, premenopausal, heterosexual women in the follicular phase of their menstrual cycle were randomly assigned to either an experimental or a control group. The experimental group was exposed to a sexually explicit videotape, while the control group saw a nonerotic videotape. Ninety minutes later both groups saw a sexually explicit videotape. Vaginal vasocongestion and hormones (cortisol, prolactin, luteinizing hormone, testosterone) were measured continuously and subjective responses were sampled at 20-min intervals. Compared to controls, experimental subjects showed a greater amplitude and longer duration vaginal response to the second videotape. Subjective measures showed greater sexual response to the second erotic videotape compared to the first, an effect that was not mediated by the hormones measured here. Prolactin decreased significantly across the session for both groups, and several behavioral and affective responses were significantly correlated with hormonal levels. Commonalities and divergence with results of prior research point to the complexity and subtlety of endocrine interactions with sexual response as well as likely sex differences in hormone-behavioral interactions.

Self-reported and genital arousal changes in sexually dysfunctional men following a sex therapy program.

This investigation examined the question of whether differences in psychophysiological and self-reported sexual response between sexually dysfunctional men and sexually functional men are reduced following treatment in a sex therapy program. Patterns of sexual responding before and after treatment in nine men with erectile difficulties and/or low sexual desire were compared with those of nine age-matched controls tested at the same intervals. Results indicated: (1) increased genital and self-reported response during the post-test in dysfunctional men but not in controls; (2) conditions eliciting performance demand produced less inhibition during the post-test in dysfunctional men; and (3) moderate correlations in dysfunctional men between clinically-assessed improvement in sexual functioning and actual changes in penile and self-reported arousal from the first to the second laboratory session. The implications of these data for the understanding of variables responsible for improved sexual functioning, and therefore, to clinical assessment and therapy, are discussed. Possible cognitive strategies are provided to account for discrepancies in self-reported and physical sexual arousal in dysfunctional subjects, and the efficacy and limitations of using psychophysiological methods in studying sexual response in dysfunctional men are suggested.

Treatment cost and rehospitalization rate in schizophrenic outpatients with a history of substance abuse.

Retrospective self-report data from 60 chronic schizophrenic outpatients in a community support program (CSP) were used to study the relationship between a history of substance abuse and rate of psychiatric rehospitalization and outpatient treatment cost. The sample showed a significant overall reduction in days spent in a psychiatric hospital or jail and in outpatient treatment expenses during the first year in the CSP. Although subjects with recent symptoms of substance abuse (N = 27) showed consistently smaller reductions than subjects with no history of substance abuse (N = 17) or subjects with no recent substance abuse symptoms (N = 16), the only significant difference between the groups was in the total number of days spent in an institution. However, the findings suggest that treatment of patients with concurrent substance abuse and schizophrenia is disproportionately more costly than that of patients without dual diagnoses.

Defining and measuring stabilization of patients during 4 years of intensive community support.

The first 4 years of an intensive community support program were evaluated in terms of key variables of patient stabilization. Patients (N = 196) had previously demonstrated an inability to manage themselves without repeated and/or lengthy hospitalizations. During program participation, there were significant reductions in hospital days and events (80%), jail incarcerations and charges, billings per patient, and stressful events. Patients reported increased satisfaction both with their lives and the program. The results support the value of continued multidimensional and multimethod examinations of patient stabilization.

Patterns of case management activity in an intensive community support program: the first year.

Changes in activity patterns of 12 case managers over the first year of an intensive community support program are described and a method and format for the collection and analysis of time budget data in case management are presented. During the first six months of the program case managers recorded the predominant activity for each 15 minute period throughout the day. Mean values of proportional time were 35.3% for direct services, 40.3% for indirect services, and 24.4% for nonclinical services. The relatively high (64.7%) combination of indirect and nonclinical services deserves careful consideration in program cost analysis.

Endocrine, psychological and genital response to sexual arousal in men.

The endocrine, genital, and cognitive--affective responses of sexually functional men were compared under sexually arousing and non-arousing conditions. Sexually aroused subjects showed significantly higher serum luteinizing hormone concentrations than non-aroused subjects. Testosterone concentration was correlated with higher levels of penile response, but it did not prime further sexual arousal. Cortisol and prolactin concentrations decreased in both groups, more in the non-aroused group, and appeared to both inhibit and facilitate sexual response, depending on the level of anxiety reported by the subjects. Cortisol was correlated with self-reported worry, and testosterone with relaxation. These results support a multidimensional approach to the endocrine study of sexual arousal that includes both cognitive and genital response components.

Issues in the use of psychophysiology to assess female sexual dysfunction.

The viability of psychophysiology as an assessment approach for female sexual function and dysfunction revolves around physiological measurement issues, subjective measurement issues, and the nature of the sexual difficulty. Recent data are presented and discussed as are the potentials and limitations inherent in a psychophysiological study of human sexuality. A case is made for the use of vaginal pressure pulse as a primary measure, vaginal blood volume as a secondary measure, correlations between subjective and objective measures of sexual arousal, and intercorrelations between various subjective affect scales.
