Psychological reactions to radiation therapy: reconsideration of the adaptive aspects of anxiety.

A common form of cancer treatment is radiation therapy. In this investigation individual differences in the psychological reactions of 45 patients undergoing external treatment were examined in the context of the Janis (1958) and linear decline models (e.g., Spielberger, Auerbach, Wadworth, Dunn, & Taulbee, 1973) of medical stressor anxiety. Evaluation included pre- and postradiation assessments of the subjects' state and trait anxiety, somatic complaints, and treatment side effects. Technologists administering the daily treatments assessed behavioral indicants of affective distress. Data analyses revealed that increases in complaints and side effects were reported by all patients at treatment conclusion. More interesting, significant changes in state anxiety were obtained from pre- to posttreatment: (a) Patients with an initial high level of anxiety reported a significant reduction, although they remained the most anxious subgroup; (b) patients with a moderate level of pretreatment anxiety reported no change; and (c) patients with low levels of anxiety reported significant increases in state anxiety. No change in trait anxiety was found for any group, suggesting that the foregoing changes in state anxiety were not simply attributable to regression. Data trends suggested that patients who were either low or high in state anxiety were also characterized by more anger or hostility than patients moderate in anxiety. The findings are consistent with the Janis model, which posits that in threatening situations the level of fear can potentially determine the adequacy of adaptation.

Evaluation apprehension and response withholding in solution of anagrams

Sixty male Ss who were classified as high or low scorers on the Sarason Test Anxiety Scale performed a difficult anagrams task either alone, before a passively observing experimenter or in the presence of an experimenter who both observed and evaluated the S's performance. Ss who were high in test anxiety attempted fewer anagrams and had fewer correct solutions in the Evaluated condition than in the Alone condition, but also had a higher proportion of correct solutions out of total attempts. Low test-anxiety Ss did not show variable performance across conditions for any measure. Follow-up studies showed that when Ss were encouraged to attempt partial solutions neither test anxiety nor experimental treatment influenced any of the measures of performance. State anxiety change scores from baseline to post-treatment assessment showed a generally negative correlation between anxiety and number of anagrams attempted. The results indicate that fear of failure engendered by test anxiety and experimenter evaluation caused Ss to withhold responding.

Cognitive imagery and physiological feedback relaxation protocols applied to clinically tense young adults: a comparison of state, trait, and physiological effects.

Examined changes in targeted and general tension behaviors as well as reductions in physiological tension associated with cognitive imagery and electromyographic biofeedback relaxation procedures. Three groups of 15 female college students participated. During three weekly sessions each person received either guided cognitive imagery relaxation, frontalis muscle feedback relaxation, or a self-rest control procedure. The Anxiety Differential was administered before and after each session, while frontalis EMG, heart rate, and skin temperature were monitored continuously. A second Temperament Analysis was administered after the final session. The imagery procedure was associated with moderate reductions in physiological tension and significant reductions in state anxiety and three tension-related personality dimensions. Self-rest persons displayed lesser reductions in general tension with little physiological change. While biofeedback persons showed the largest reductions in physiological tension, they displayed only small and variable changes in state anxiety and personality dimensions. The data raise continued questions about the application of physiologically based operant relaxation procedures and support the use of cognitively mediated protocols for the treatment of specific or general anxiety behaviors.

Anxiety, information, interpersonal impacts, and adjustment to a stressful health care situation.

Forty patients scheduled for dental extraction surgery were given either specific or general preparatory information, and this information was presented in either a personalized or relatively impersonal fashion using nonverbal cues. Changes in state anxiety over the course of the experiment were accounted for by individual differences in the Dental Anxiety Scale. The most important determinant of adjustment during surgery was the congruence between specificity of information received and individual differences in preference for information as measured by the Information subscale of the Krantz Health Opinion Survey (KHOS; Krantz, Baum, & Wideman, 1980). Findings with the KHOS and the Dental Anxiety Scale are examples of the growing importance of situation-specific personality-trait measures. The finding that high levels of presurgery anxiety are associated with poor adjustment is discussed in terms of Janis's (1958) model. Patients' perceptions of information-giver hostility and dominance were also significantly (inversely) related to adjustment; the differential impact of informational versus interpersonal variables is discussed in terms of moderating characteristics of health care settings.

Effects of dogmatism on state anxiety during the analysis and synthesis of new beliefs.

Investigated the concept of dogmatism as a defense mechanism and the role of threat in the synthesis of new beliefs by examining the effects of dogmatism on changes in state anxiety (A-State) during the analysis and synthesis of new beliefs. Sixty female college students were selected on the basis of extreme scores on the Dogmatism Scale and the trait anxiety (A-Trait) scale of the State-Trait Anxiety Inventory to work on a task requiring the analysis and synthesis of new beliefs. In support of Rokeach's theory, high dogmatics displayed no change in A-State from the analysis to the synthesis period of the task, while low dogmatics exhibited a significant decline in A-State between the two periods. The clinical implications of these findings were discussed in terms of the role of dogmatism in the processing of personality interpretations and test feedback.

State anxiety, physical activity, and urinary 3-methoxy-4-hydroxyphenethylene glycol excretion.

Measurement of urinary 3-methoxy-4-hydroxyphenethylene glycol (MHPG) levels has been suggested as possibly being important in elucidating the role of central noradrenergic function in affective illnesses. The influence on urinary MHPG excretion of the state variables of physical activity and stress has not been clearly defined in previous studies. During a baseline medication-free period, 24 hospitalized depressed female patients underwent a five-day protocol including an eight-hour period of either enhanced or restricted activity. Throughout the protocol, independent measurements of telemetered mobility and stale anxiety were obtained. There were no significant effects of physical activity on urinary MHPG levels. Furthermore, baseline urinary MHPG levels and baseline state anxiety did not covary significantly. However, within-individual analyses yielded a highly significant relationship between changes in urinary MHPG levels and changes in state anxiety. The data suggested that those patients with lower baseline MHPG levels were those more prone to experience increased anxiety under environmentally "activating" circumstances.

Training and Transfer of Training Effects in EMG Biofeedback Assisted Muscular Relaxation

ABSTRACTTwenty‐two normal adults participated in an electromyographic (EMG) biofeedback experiment designed to test if the feedback stimulus is necessary in obtaining EMG reductions during typical laboratory procedures, and if prior training on one muscle facilitates the training of a second muscle. One group of subjects received forearm feedback training followed by frontalis training. A second group received training in the reverse order. Two control groups relaxed first on their own followed by either forearm or frontalis training. Attention was directed toward motivating control subjects to perform maximally during relaxation without feedback. Heart and respiration rates and skin conductance and temperature were also recorded. Both trained and untrained subjects produced significant EMG reductions but did not differ from each other; nor did a transfer of training effect emerge. No differences resulted between feedback and non‐feedback conditions for the other physiological measures or for changes in state anxiety. These data compromise somewhat the previous demonstrations of EMG biofeedback “learning,” and are unsupportive of EMG biofeedback as a general relaxation training technique.

Test-induced anxiety with children.

Thirty-five elementary school children received the WISC, Rorschach, CAT, and Sentence Completion Test in counterbalanced order with a test-test interval of approximately 24 hours. State and trait anxiety measures were assessed immediately prior to and immediately following each test administration. Results indicated that state anxiety measures increased significantly following administration of the more ambigious and school related assessment tests, namely the Rorschach and WISC. In contrast, the more structured, less amorphous CAT and Sentence Completion Test, did not induce any significant changes in state anxiety. In all cases, trait anxiety measures remained relatively stable. Implications for assessment techniques with children were discussed.

The effects of personality tests on state and trait anxiety.

Summary 52 college student volunteers received the MMPI, Rorschach, TAT, and Sentence Completion Test in counterbalanced order with a test-retest interval of approximately 24 hours. State and trait anxiety measures were assessed immediately prior to and immediately following each test administration. Results indicated that state anxiety measures increased significantly following administration of the more ambiguous, unstructured test stimuli, namely the Rorschach and TAT. In contrast, the more structured, direct assessment methods, namely the MMPI and Sentence Completion Test, did not induce any significant changes in state anxiety. In all cases, trait anxiety measures remained relatively stable.
