Role-played and hypnotically induced simulation of psychopathology on the MMPI.

The differential effects of role-played vs. hypnotically induced simulation of a paranoid syndrome on diagnostic and validity scales of the MMPI were tested with 30 female undergraduate Ss. Hypnotized Ss given the paranoid syndrome suggestion simulated the MMPI more accurately than did role-playing Ss. The F scale and Gough F-K index of dissimulation identified the role-playing group, but not the hypnosis with simulation suggestion group. It was concluded that further refinement of the validity scales of the MMPI is needed to improve their effectiveness in detecting deception on this test.

Fluid and rigid boundaries of paranoid and nonparanoid schizophrenics on a role-playing task.

The concepts of fluid and rigid boundaries were assessed in an improvisational role-playing task in an attempt to differentiate paranoid from nonparanoid schizophrenics. Thirty-one schizophrenic patients divided into paranoid, intermediate, and nonparanoid groups were given an improvisational role-playing task. The resulting scenes were analyzed by Fluid Boundary and Rigid Boundary scales, which were developed on the basis of specific aspects of the physical and verbal representations of characters, objects, and settings. The hypothesis that variations in the disruption or emphasis of representational boundaries differentiate paranoid and nonparanoid symptomatology received support. Paranoid schizophrenics scored higher on the Rigid Boundary scale, i.e erecting and/or exaggerating physical and interpersonal boundaries; and nonparanoid schizophrenics scored higher on Fluid Boundary scale, i.e. showing fused and fluid representations of characters, objects, and settings. Improvisational role-playing seems to hold promise as a medium with diagnostic value.

[Importance of role playing in a professional training group].

Role playing constitutes a precious instrument in training responible people for help relations. It permits to by-pass defense mechanisms through induced avoidance in group situation. It makes personal involvment easier, for efforts as well as for representations, and permits to confront reality in the other person. Under the control of the animator, the player has always the right to limit his personal involvment within the boundaries he wishes : this combination of facilitation and involvment framing is especially interesting.

Objective detection of faking on role-play tests of assertion: gender differences.

The validity of role-play tests of assertiveness can be reduced by the effects of faking. Kern demonstrated that faking could be detected using assessors' global judgements. The present analysis is based on Kern's 1994 videotapes, examining the effectiveness of more objective measures. Undergraduates who were low in assertiveness and instructed to fake high assertiveness on the Idiographic Role-play Test (n = 23) emitted more statements indicative of social-evaluative concerns than the veridically highly assertive testees (n = 27). Significant gender differences in the detectability of faking were also obtained. Whereas 24 female fakers and nonfakers were differentiated via verbalizations of likability, 26 male fakers and nonfakers were differentiated via empathic-assertive statements. The implications and limitations of this method to detect faking are discussed.

Detection of faking on role-play tests of assertiveness.

Faking and demand characteristics can represent significant threats to the validity of role-play tests of social competence. The present study examined whether faking could be detected via the global judgments of experienced and inexperienced assessors. 26 undergraduates low in assertiveness were induced to fake their performances on the Idiographic Role-play Test via instructions and information. Experienced judges successfully differentiated faking subjects from highly assertive subjects (n = 27) who had been provided with information and nonfaking instructions (98% accuracy). Inexperienced assessors correctly classified 79% of the subjects. Within the discussed limitations of this study, it appears that it is possible to detect faking on role-play tests of assertiveness.

Circadian synchronization of liver regeneration in adult rats: the role played by adrenal hormones.

The role played by the adrenal hormones in the regulation of liver proliferation in adult rats was investigated under various experimental conditions. In untreated control groups, cell growth was very low and endogenous corticosterone levels showed a clearly-defined circadian rhythm with a peak in the evening. Adrenalectomy depressed the level of endogenous corticosterone immediately and the growth rate of the liver increased significantly. We were able to prevent this effect by repeated injections of corticosterone at physiological doses. After a 1/3 hepatectomy and a sham-operation, the corticosterone blood level maintained its normal circadian pattern with the exception of a transient increase during the first two post-operative hours. After a hepatectomy of this kind, a negative correlation was found to exist between the adrenal hormone level and the waves of DNA synthesis; the subsequent mitoses appeared in two successive circadian waves of decreasing amplitude, a maximum value being reached in the morning. In rats submitted to a 1/3 hepatectomy and an adrenalectomy simultaneously, the endogenous corticosterone level fell significantly after a post-operative peak. The regenerating pattern was completely different from that induced by 1/3 hepatectomy alone. The rise in the labelling index began earlier and rose to significantly higher values; it was then followed by a single large mitotic wave without any circadian rhythm. These results favour the hypothesis that adrenal hormones have a significant effect on the negative control of liver regeneration. Circadian changes in the corticosterone level were responsible for the nycthemeral pattern observed in the regenerating liver after a partial hepatectomy. The results show a marked inhibition of the G1-S transition, particularly in the evening, when the endogenous corticosterone concentration was at its highest. Also discussed is the relationship between corticoids and 'chalones', which synergetically inhibit the passage from G0 into the cell cycle.

The use of role-play in teaching medical students obstetrics and gynaecology.

There is a great need to review and critically assess medical education. Role-play has seen increasing use as an educational tool. We investigated its role in a 'conventional speciality', Obstetrics and Gynaecology. This is a part of the medical curriculum where communication skills are particularly important, but difficult to learn in practice. Twenty-one medical students took part in three role-play case studies. An innovation we implemented was the use of 'time outs' which could be called at any time through a session. After the exercise students were required to complete a questionnaire designed to probe their attitudes towards the experience. The results indicate that this technique can be successfully used in teaching a conventional speciality. Unlike some previous studies we also found this to be a satisfactory tool in teaching the factual part of the course. We found the 'time out' innovation to be an important aid. We argue that there is an important niche for role-play in medical education.

Can we insulate trainee nurses from exposure to bad practice? A study of role play in communicating bad news to patients.

This paper investigates the effects of three different role models in teaching trainee nurses to cope with the sensitive task of communicating a traumatic event to patients or their relatives. This is a long-standing problem with a high level of dissatisfaction within the field of nurse training. This study, in contrast to other studies of telling bad news (TBN), has focused on the person who gave rather than received bad news. This study also reinforces the view that role play and role modelling are not only effective learning methods in nurse training but are natural methods of learning in the profession. Student nurses are constantly exposed to other people's attempts at caring. Eighteen student nurses were randomly selected from a total student intake of 66 students for study in depth. Nine main skills were identified in a TBN task. Six student nurses were exposed to negative examples of a novice telling bad news, six to an expert model doing it and six to both models. The results showed that nurses learned quickly from role models, whether it was the negative instance of a poor model or the positive instance of an expert model or a combination of both. No significant difference in effectiveness between the three models was observed. The findings are discussed with reference to implications for nursing education in general.

An exercise in critical thinking using role playing.

Attitudes, knowledge, and skills of critical thinking are developed in a role-playing simulation. Using diabetes mellitus, students solve lifelike problems within the role-playing experience, develop sensitivity and awareness of another's life experience with illness, and generate empathy toward persons with diabetes. Critical thinking is demonstrated in student's double-entry journals.

A comparative test of the developmental, role-playing, and defensive explanations of offspring identification.

Following Mussen and Distler (1959) and Bandura, Ross and Ross (1963), the developmental, defensive, and role-playing theories of identification are tested on high school seniors. Previous tests have supported the developmental and role-playing hypotheses about equally, while the defensive hypothesis lacks consistent empirical support. Questions are raised, however, about the merit of these tests. Data are presented on seniors in an Eastern suburban school and a Midwestern small town school which support the developmental (warmth) hypothesis but which are inconsistent with the defensive and role-playing hypotheses. Parental behavior is measured by the Bronfenbrenner Parent Behavior Questionnaire and identification is measured by the semantic differential.

Effect of the medication management module evaluated using the role play test.

Training in social skills has been shown to have a strong, positive impact, according to behavioral measures, on social skills, self-rated assertiveness, and the hospital discharge rate. It is important to establish a system of assessing social skills because it is necessary for the effects of social skills training to be assessed in Japan. In Project 1, we devised a Japanese version of the role play test to quantify social skills using a standard method. We tested 30 patients attending the day hospital who were considered to need intensive rehabilitation. We found the role play test had high inter-rater and test-retest reliability, and had construct validity and criterion related validity. Thus, the role play test was thought to be a useful tool for assessing social skills. For Project 2, eight inpatients who were ready for discharge but who needed to improve their skills in self-managed medication participated in this study. The social skills of self-managed medication assessed using the role play test were significantly improved after the subjects participated in the Medication Management Module of the UCLA social and independent living skills program. Knowledge of self-managed medication also tended to improve after training. This study is preliminary and it should be confirmed that improved skills influenced by the medication management module decreases the relapse rates.

Rapid changes in cellular immunity following a confrontational role-play stressor.

Recent laboratory studies have shown several immune system changes consistently associated with brief stress including increases in circulating natural killer (NK) cell numbers, increases in NK cell cytotoxicity (NKCC), increases in suppressor cytotoxic (CD8) T cell numbers, and decreases in the in vitro proliferative response to mitogen stimulation. In the present study, we use a confrontational role-play, which brings out responses varying from assertion to capitulation and examine the psychological, behavioral, physiological, and immune system responses to this task compared to a resting control task. Compared to the control condition, the brief confrontational role-play led to significant subjective and physiological arousal and increases in circulating NK (CD16, CD56) as well as large granular lymphocyte (CD57) cells and suppressor/cytotoxic T cells (CD8). There were also significant relationships between stress-related increases in the cardiovascular measures and the numbers of circulating NK cells. These findings support sympathetic nervous system activation as a primary mechanism for increases in NK cell numbers under challenge. These role-play results are generally consistent with those from other laboratory tasks such as mental arithmetic. However, in contrast to previously examined brief stressors, the role-play led to decreased NKCC adjusted for percentage of NK cells. This apparent differential change in NK cytotoxicity across different types of activating experimental tasks points to the importance of examining dimensions of the behavioral and emotional response to challenge or threat in addition to that of autonomic arousal.

Testing health care professionals' communication skills: the usefulness of highly emotional standardized role-playing sessions with simulators.

Although standardized role-playing sessions (SRPS) with simulators are increasingly used to assess health care professionals' (HCPs) communication skills (CS) and the effectiveness of training workshops (TWs), nothing has been done to date to define the optimal emotional content of SRPS. Three emotionally different SRPS contexts-weakly emotional (WE-), moderately emotional (ME-), and highly emotional (HE-SRPS)-were, therefore, tested in order to assess induced CS and sensitivity to TW-related changes. The study included 25 HCPs. Tape-recorded SRPS, scheduled before and after the TW, were retranscribed, and assessed according to the Cancer Research Campaign Workshop Evaluation Manual (CRCWEM), which provides a rating of form, function and structure for each utterance. Results show that induced CS are different in WE-, ME-, and HE-SRPS, regarding form (HE-SRPS induced more 'directing', 'leading' or 'multiple' questions; WE: 20.7%; ME: 19.7%; HE: 33.7% (p<0.001)); function (HE-SRPS induced more 'inappropriate' information; WE: 6. 5%; ME: 8.2%; HE: 15.6% (p<0.001)); and blocking (HE-SRPS induced more 'blocking' utterances; WE: 7.2%; ME: 13.8%; HE: 30.2% (p<0. 0001)). Finally, CS changes induced by TWs are the highest in HE-SRPS (14.8% increase of 'open' questions for the HE- versus 1.0% for the WE-SRPS; 11.6% decrease of 'inappropriate' information for the HE- versus 3.3% for the WE-SRPS; and 17.5% decrease of 'blocking' for the HE- versus 2.6% for the WE-SRPS). In conclusion, SRPS, with a HE content, induce more inappropriate CS. Moreover, they are more sensitive to TW effects. SRPS with a HE content should, thus, be recommended for the assessment of TW effectiveness.

The effects of role-playing high gender identification on the California Psychological Inventory.

This study of the California Psychological Inventory (CPI) demonstrates that subjects can alter significantly their CPI profiles through role-playing high gender identification, i.e., males attempt to appear more masculine and women attempt to appear more feminine. The majority of these subjects did so without being detected by the validity scales designed to detect faking good or bad. Thirty-two volunteers, 16 male and 16 female, participated as subjects. A 2 X 2 ANOVA (subject gender by instructions to role-play vs. standard instructions) design was used. A significant main effect (p less than .01) for instructions was found on 14 of 18 scales and a significant interaction effect (p less than .01) on 4 of 18 scales. The profiles from the role-playing subjects indicate that the stereotypes of both genders, as seen by these subjects, are maladaptive. Implications for practical application of these findings are discussed.

The use of role plays in teaching drug and alcohol management.

This is an evaluation of the use of role plays to teach drug and alcohol assessment and management skills to medical students as part of their general practice training. Role plays of 'real life' scenarios enable students to evaluate their own learning experiences. This method facilitates effective peer discussion of clinical and ethical issues with a high degree of acceptability to both students and teachers.

Measurement of assertive behavior: construct and predictive validity of self-report, role-playing, and in-vivo measures.

Examined the predictive validity and construct equivalence of the three major procedures used to measure assertive behavior: Self-report, behavioral role-playing, and in-vivo assessment. Seventy-five Ss, who spanned the range of assertiveness, completed two self-report measures of assertiveness, the Rathus Assertiveness Scale (RAS) and the College Self-Expression Scale (CSES); two scales from the Endler S-R Inventory of General Trait Anxiousness, the interpersonal and general anxiety scales; eight role-playing situations that involved the expression of positive and negative assertiveness; and a telephone in-vivo task. In general, the study revealed the following: (1) assertiveness measures are task-dependent in that there was more overlap within task than between tasks; (2) there is a moderate degree of correspondence between self-report and role-playing measures, although this was true only for negative assertion; (3) positive and negative assertion do not appear to have the same topography of responding; and (4) there appears to be no consistent relationship between the in-vivo measure and any other type of assertiveness measure.

An investigation of the role played by the superior colliculus and ventromedial thalamus in self-injurious behavior produced by intranigral microinjection of muscimol.

Bilateral injection of muscimol (30 or 60 ng) into the substantia nigra (pars reticulata) of rats produced a variety of stereotyped acts, self-injurious behavior (SIB), and antinociception. Bilateral electrolytic lesions of the superior colliculus strongly suppressed SIB without reducing the antinociceptive effects of intranigral muscimol. Electrolytic lesions of the ventromedial thalamus had no effect on behavioral responses to intranigral muscimol. These studies suggest that the SIB produced by intranigral muscimol is mediated by neuronal pathways that terminate in or pass through the superior colliculus. The ventromedial thalamus does not appear to play a role in mediating behavioral responses to intranigral muscimol.
