Compression induced damage on in-situ severed and intact nerves.

The effect of rapid as well as sustained compressive forces applied to the surface of intact and severed peroneal nerves of rabbits was studied. Considerable effort was taken to ensure a quantitative and consistent experimental paradigm. Stimuli were delivered to the sciatic nerve, and the compound action potential was recorded in the peroneal nerve, with compressive forces applied more proximally on the peroneal nerve. It was found that the conduction of action potentials on the larger nerve fibers was more sensitive to compressive force than that of the smaller nerve fibers, although all nerve fibers stopped conducting when sufficient compression was applied to the nerve. The effect on the conduction of action potentials on the nerve fibers appeared to be determined both by Laplace's law (as previously reported by others) and the viscoelastic properties of the entire nerve. Relatively low compressive forces (20 gm applied over approximately 7 sq mm) were found to decrease the neutral conduction of the larger nerve fibers for at least two hours, whereas stagnation of blood circulation was not found to affect measurably the neural conduction of all the nerve fibers for up to two hours.

Genital herpes and personality.

Genital herpes, while having gained considerable attention as an important psychosexual disease, is not well understood. Precisely what factors trigger infectious reactivation is an important question that has yet to be answered. The present study investigated the relationship between recurrent genital herpes and personality. High and low recurrers were administered a demographic and disease history questionnaire and the Minnesota Multiphasic Personality Inventory (MMPI). Results revealed that, compared to low recurrers, the mean MMPI profile of high recurrers showed significantly greater elevations on nine of ten scales. The degree and pattern of elevation in the high profile is consistent with increased levels of autonomic arousal and stress. These findings are interpreted as suggestive of the possible role of personality in influencing the rate of infectious recurrence in genital herpes sufferers. The implications for psychologically based treatment strategies are discussed.

Therapeugenic factors in psychotherapy: the effects of fee and title on credibility and attraction.

Led male (N = 69) and female (N = 75) Ss to believe that they were rating the accuracy of a description of a mental health professional used to help clients choose their therapist. Ss were exposed to descriptions that were identical in content, with exception of the level of fee, high vs. low, and the title of the therapist, psychiatrist vs. clinical psychologist vs. counselor. Ss were asked to rate the individual in the description on various dimensions of credibility and attraction. The results indicate that Ss were not affected by the level of fee charged except on their willingness to seek therapy from the therapist. Ss consistently rated the psychiatrist higher than the counselor, who in turn was rated higher than the clinical psychologist. Explanations for this and the implications of these findings are discussed.

Anxiety management with schizophrenic outpatients.

Current theoretical speculation and research evidence suggest that elevated anxiety levels and poor anxiety coping skills may be important aspects of the schizophrenic process. Despite the success of various behaviorally oriented stress management techniques with nonpsychotic individuals, research on the effects of these programs as applied to schizophrenics has been scarce. The present study examined the effects of two such techniques, Anxiety Management Training (AMT) and Applied Relaxation Training (R), on schizophrenic outpatients. After 6 weeks of training, both the AMT and R Ss (N = 27) reported significantly lower levels of generalized anxiety on a standard measure, as contrasted to non-treated Wait-List (WL) group Ss (N = 12). In addition, significant positive changes were reported by the Ss' regular outpatient therapists on a number of related, non-targeted behaviors. The results of this study support the idea that short-term anxiety management interventions may be useful in the treatment of schizophrenic patients.

Type A behavior and upper respiratory infections.

The present study investigates the relationship between upper respiratory infection (URI) and Type A behavior pattern. Type A and Type B college students completed a health survey which measured both incidence of and response to URI's. Overall, results revealed a pattern indicating that Type A's reported experiencing significantly more URI's than did their Type B counterparts, and that female Type A's reported significantly more frequent URI's than did female type B's. The results were discussed in terms of the Type A's stressful life style increasing his/her susceptibility to viral respiratory disease. The Type A's propensity to minimize or failure to attend to illness symptoms was also discussed.

Reputation, training, fee, and androgyny: their comparative effects on impressions of therapist credibility.

Two hundred and forty-eight college students viewed a vignette from a therapy-analogue session. Before Ss viewed the vignette they all read a summary that described the vignette plus an additional description that stressed different aspects of the therapist. One-fifth of the Ss were told of the therapist's excellent reputation, one-fifth were told of the therapist's excellent training and credentials, one-fifth were told of the therapist's high fee, and one-fifth were told of the therapists' androgenous personality. The remaining one-fifth of the Ss, who served as controls, were told nothing further; they only received the standard description of the vignette. After the vignette, Ss completed measures designed to assess their perception of therapist credibility and attractiveness. The results indicate that the androgenous therapist was rated as most credible and attractive (whereas the high-fee-charging therapist was least credible and attractive.) Explanation for these results and implications are discussed.

Attraction to therapy and therapist credibility as a function of therapy orientation.

Exposed male and female Ss (N = 96) to psychoanalytic, behavioral, client-centered, or gestalt therapy, in the form of a brief written description and a 5-minute videotaped simulation. Attraction to therapy and various dimensions of therapist credibility were measured. The psychoanalytic presentation generated the greatest attraction and the greatest perceived total credibility. The gestalt presentation was next highest on these variables, followed by the behavioral and client-centered presentation. No significant effects for sex of S or sex by therapy approach interaction were reported. Explanations for and implications of these findings are discussed.

Effectiveness of complementary projection in reducing stress.

Threatened Ss in five stress groups with electric shock, while Ss in a sixth group were not threatened. In one of the stress groups Ss were encouraged to project causality for their feelings that resulted from the threat of shock to the E instead of to the shock, while Ss in the remaining stress groups were not encouraged to project causality for the threat-produced affects to the E. Physiological and self-report measures indicated that Ss who projected their anxiety and nervousness to the E were just as distressed by the veridical source of arousal as were Ss who did not project. Implications of these results for the hypothesized stress-reducing effectiveness of complementary projection were discussed.

Therapeugenic factors in psychotherapy: the use of psychological tests.

In the first part of the experiment all Ss were administered a battery of psychological tests that they were told would provide an accurate description of their personality. Two weeks later, Ss were contacted and asked to participate in the second half of the experiment. Half of the Ss were led to believe that the psychological assessment indicated that they could remain calm and relaxed when exposed to a stressful situation (therapeutic suggestion), while the other half did not receive this feedback (no suggestion). Half of the Ss then were exposed to a stressful situation (threat), while the other half were not (no threat); the effectiveness of the diagnostic predictions was assessed via physiological and self-report measures of arousal. Results indicated that (a) the threat manipulation was effective in creating stress; and (b) Ss given therapeutic-suggestion feedback based on the psychological assessment were able to remain significantly more calm and relaxed in the experiment than Ss who did not receive therapeutic suggestions. Implications for the use of psychological testing and diagnostic feedback as a technique of social influence are discussed.

Anxiety management training for pattern A behavior.

During a 3-week period, seven subjects were treated with Anxiety Management Training (AMT) while seven subjects served as a wait-list control. Pattern A behaviors, measured by the Jenkins Activity Survey (JAS), self-report of anxiety, as measured by the Spielberger state (STAI-S) and trait (STAI-T) anxiety inventories, and indices of blood pressure, cholesterol, and triglycerides were obtained before and after treatment. Results indicate that treated subjects compared to controls showed significant reductions in the Hard-Driving component of pattern A behavior, showed lower posttest STAI-A and StAI-T scores, but failed to evidence a statistically significant reduction in systolic and diastolic blood pressure or cholesterol and triglyceride levels. The implications of these data to theoretical and practical conceptualizations of stress management are discussed.

Positive evaluation of stressful experiences.

Two studies were conducted to test the hypothesis that the more stressful an experience is, the more positively it will be evaluated. Stressfulness was manipulated in the two studies by means of threat of shock, and both self-report and physiological measures of stress indicated that these manipulations were highly successful. In both studies subjects who were exposed to the more stressful situation evaluated their experience as significantly more worthwhile and somewhat more interesting than did subjects exposed to the less stressful situation. Furthermore, as expected, subjects did not like the high stress experience more than the low stress experience. Implications and qualifications of these findings are discussed.

Dysmenorrhea and personality.

The experiment examined whether reliable personality differences exist between (a) women who suffer from spasmodic and congestive dysmenorrhea and (b) women who experience dysmenorrhea and women who do not. A sample of 12 congestive dysmenorrhea sufferers, 12 spasmodic dysmenorrhea suffers, and 24 nonsufferers obtained from a larger sample of university women, completed the Menstrual Symptom Questionnaire, Minnesota Multiphasic Personality Inventory, Tennessee Self-Concept Scale, and Personality Research Form. Results indicated that congestive sufferers differed from spasmodic sufferers only in their level of impulsivity. However, dysmenorrhea sufferers differed significantly from nonsufferers in that dysmenorrhea sufferers were more similar to a neurotic sample, were depressed, anxious and introverted, and less independent, playful, satisfied with themselves, positive about their physical and social selves than nonsufferers. In spite of these differences, standard scores from the personality measures suggested that dysmenorrhea sufferers were not maladjusted.

Psychotherapists' perceptions of clients' satisfaction following termination.

The present investigation sought to examine psychotherapists' perception of client's satisfaction following termination. During a 6-mo. period, 86 clients who terminated treatment at a large mental health center were asked to evaluate the service that they had received from their therapists. Therapists were also asked to predict how their clients would evaluate them. Results indicated that clients were favorably impressed with the services provided by their therapists and therapists tended to underestimate the worth of their services. Further conclusions, which at this point can only be speculative due to the limited sample, were that there were no differences in reported satisfaction of clients among psychiatrists, psychologists, psychiatric social workers and para-professional groups, but psychiatrists predicted significantly greater satisfication by satisfaction by clients than the other groups. They were the only group which predicted more satisfaction by clients then was actually reported.

Acceptance of general personality interpretations prior to and after receipt of diagnostic feedback supposedly based on psychological, graphological, and astrological assessment procedures.

There was no difference in the acceptance of a general personality interpretation supposedly based on psychological, graphological, or astrological assessment procedures. Ss told that their general personality interpretation was based on one of the three assessment procedures, however, accepted the interpretation to a greater degree than did Ss told the interpretation was "generally true of people." S faith in all assessment procedures and perceived diagnostician skill increased significantly from before to after receipt of the diagnostic feedback. Ss elicited a halo response after they had received the interpretation, such that they generated a highly consistent positive (or negative) view of the assessment procedures and diagnostician skills. Implications of results from this acceptance paradigm were discussed for diagnosticians and therapists.

The psychological effects of vasectomy for American men.

Evidence concerning the psychological effects of vasectomy for American men was reviewed. Surveys of postoperative sexual behavior, satisfaction, and/or happiness suggest that the effects of vasectomy are generally positive. Data from studies employing clinical interviews and/or psychological tests, however, support a very different conclusion. These investigations which are generally superior in methodology and measurement techniques to the survey studies indicate that (a) although men in general verbally express satisfaction with vasectomy, many men are probably describing feelings which have been distorted as part of an attempt to cope with their private concerns about the consequences of the operation; and (b) many men experience some difficulty in adjusting to the psychological consequences of vasectomy. Implications for future research are discussed.
