    Psychological and Physiological Variables Associated With Large Magnitude Voluntary Heart Rate Changes (1975)

    Notizen: Forty subjects, given binary and proportional auditory and visual feedback and asked to raise and lower their heart rate on signal, were able to produce increases of up to 46 bpm and decreases of up to 14 bpm, with a mean increase over 5 experimental days of 11 bpm and a decrease of 5 bpm. Increases in both diastolic and systolic blood pressure and increases in skin potential level and number of skin potential responses accompanied voluntary increases in heart rate but not decreases. Subjects with the highest resting heart rate variability and skin potential level were best able to raise their heart rate. Subjects with the highest resting heart rate and highest resting heart rate variability were best able to decrease the heart rate. Subjects with high Ego Strength scores (or low Welsh's Factor A scores) on the MMPI were best able to control their heart rate. The Ego Strength score, resting heart rate, and resting heart rate variability were all significantly intercorrelated. Subjects showed marked individual differences in ability to control heart rate, although there was a significant correlation between ability to raise and ability to lower heart rate.

    Large Magnitude Heart Rate Changes in Subjects Instructed to Change Their Heart Rates and Given Exteroceptive Feedback (1972)
    Oxford, UK : Blackwell Publishing Ltd
    Psychophysiology 9 (1972), S. 0

    Notizen: Four subjects who were given exteroceptive, auditory and visual feedback, and were asked to raise and to lower their heart rate on signal, were able to produce large magnitude changes in both directions. The fact that some of these changes occurred immediately suggests that feedback may not be as important as some authors have suggested. Respiratory changes and changes in muscle tension did not appear to be mediators.

    A controlled study of the effects of diphenylhydantoin on anxiety, irritability, and anger in neurotic outpatients (1970)
    Springer
    Psychopharmacology 17 (1970), S. 169-181 
    Details
    ISSN: 1432-2072
    Schlagwort(e): Psychopharmacology ; Diphenylhydantoin ; Anxiety ; Hostility ; Psychiatric Status Rating Scales

    Thema: Medizin
    Notizen: Summary In a six-week double-blind cross-over study, DPH, 100 mg, t.i.d., was found to be markedly more effective than DPH, 5 mg, t.i.d., used as a placebo, in reducing symptoms relating to anger, irritability, impatience, and anxiety. The psychoactive properties of DPH were demonstrated by both self-ratings and physician ratings of change. Improvement when changing from 5 mg to 100 mg was matched by worsening when changing from 100 mg to 5 mg. Patients in the controlled study were selected on the basis of the presence of symptoms of anger, irritability, and anxiety, a social class more typical of private patients than clinic patients, and a Barron Ego Strength score of 40 or above. No undesirable side effects were encountered.

    Diphenylhydantoin and phenobarbital in the relief of psychoneurotic symptoms (1972)
    Springer
    Psychopharmacology 27 (1972), S. 67-84

    Notizen: Abstract This study is a double-blind comparison of the clinical effects of diphenylhydantoin (DPH) and phenobarbital among 80 adult psychoneurotic, non-epileptic outpatients. Patients were assigned at random to eight weeks of treatment with DPH 300 mg or phenobarbital 90 mg daily. During this time, patients were followed in brief bi-weekly interviews by one of two treating psychiatrists. At each visit, the patient's clinical condition was evaluated by the patient's ratings of distress on a factored list of 65 common psychoneurotic symptoms, on a mood adjective checklist, on the Psychiatric Evaluation Profile and on a global scale of change, and by the doctor's ratings on several global scales of change. Each criterion was analyzed with respect to initial score, medication, doctor and the medication by doctor interaction. The one doctor's patients responded better than the other doctor's patients. The results suggested that DPH and phenobarbital in the doses employed had similar effects on psychoneurotic symptoms. More extensive analyses of one patient rating and one doctor rating were performed to look for characteristics of the patient or the treatment situation that might affect medication responses. No useful predictors of differential response to the two medications appeared. Patients with brief illnesses, no prior psychiatric care and no previous phenothiazines or antidepressants responded better than their counterparts to both medications. Some patients who terminated prematurely reported very marked improvement—even more than most patients who completed the prescribed course of treatment. This observation challenges the usual assumption that drop-outs represent treatment failures. The equivocal results with regard to medication effects point up the potential value of studies designed to produce dose-response information.
