"I Know Just How You Feel": The Validity of Healthy Women's Perceptions of Breast-Cancer Patients Receiving Treatment

The accuracy of healthy women's perceptions of how breast-cancer patients cope with treatment was assessed in this study. Standardized questionnaires measuring distress, coping, and illness perceptions were completed by 78 women undergoing postsurgical treatment for primary breast cancer. The patients' responses were then compared with assessments made by a matched community sample. The results showed a marked incongruity between healthy women's perceptions and actual patients' experiences of the disease and its treatment. Community women overestimated patients' distress, perceived the consequences of breast cancer to be more severe, and were more likely to believe that patients used denial and disengagement strategies. The discrepancy in findings has implications for the appropriateness of the support offered to patients by healthy women.     

Prevalence of Disordered Eating Behaviors and Bulimia Nervosa in a Sample of Mexican American Female College Students

Disordered eating behaviors and bulimia nervosa were examined in a sample of female Mexican Americans. Results showed that 1.4% to 4.3% could be classified with bulimia. Just over 11% indicated regular binge eating; dieting and exercising were the primary techniques used for weight control. Implications for intervention are briefly discussed.     

Enhancing treatment effectiveness through social modelling: A pilot study

Objective: Medical treatments take place in social contexts; however, little research has investigated how social modelling might influence treatment outcomes. This experimental pilot study investigated social modelling of treatment effectiveness and placebo treatment outcomes.

Design: Fifty-nine participants took part in the study, ostensibly examining the use of beta-blockers (actually placebos) for examination anxiety. Participants were randomly assigned to observe a female confederate report positive treatment effects (reduced heart rate, relaxed, calm) or feeling no different.

Main outcome measures: Heart rate, anxiety and blood pressure were assessed, as were symptoms and attributed side effects.

Results: Heart rate decreased significantly more in the social modelling compared to control condition, p = .027 (d = .63), and there were trends towards effects in the same direction for both anxiety, p = .097 (d = .46), and systolic blood pressure, p = .077 (d = .51). Significant pre-post placebo differences in heart rate, anxiety and diastolic blood pressure were found in the social modelling group, ps < .007 (ds = .77–1.37), but not the control condition, ps > .28 (ds = .09–.59).

Conclusions: Social observation of medication effectiveness enhanced placebo effectiveness in heart rate, and showed a trend towards enhancing treatment effectiveness in both anxiety and systolic blood pressure. Social modelling may have utility in enhancing the effectiveness of many active medical treatments.     

Acute effects of viloxazine HCl and flurazepam when given alone and in combination on sleep EEG: A double-blind interaction study with normals

Viloxazine, an aryl-oxypropanolamine type β-adreno-receptor antagonist, has been used in the treatment of depression. In a double-blind drug interaction study with flurazepam, a commonly used benzodiazepine hypnotic, viloxazine administered alone decreased the amount of time spent in REM sleep, increased the amount of time in the “light” stages of sleep, and increased the number of transitions to awake. However, no interactive effects of the combined administration of viloxazine and flurazepam could be detected.     

Male body satisfaction: factorial and construct validity of the Body Parts Satisfaction Scale for Men

Given the centrality of body dissatisfaction in the manifestation of eating, exercise, and affective disturbances in men, measurement of this construct becomes essential. Across 2 studies with male undergraduates (Ns = 189 and 188), the psychometric properties, including incremental validity and factor structure, of the 25-item Body Parts Satisfaction Scale for Men (BPSS-M) were examined. Three factors--Upper Body, Legs, and Face--that included items measuring both muscularity and leanness were established. The factors were internally consistent and temporally stable (over 6 months), and support was found for their convergent, discriminant, and concurrent validity. Further, we established that, after controlling for social desirability and drive for muscularity, body satisfaction contributes uniquely to men's experience of disordered eating, negative affect and mood, and psychological well-being. The BPSS-M yielded reliable and valid scores with undergraduate men, suggesting that it may be useful for understanding not only body satisfaction but disordered eating and affective disturbances as well.     

A systematic review and meta-analysis of the Brief Illness Perception Questionnaire

Objective: This paper aims to systematically review the use and performance of the Brief Illness Perception Questionnaire (Brief IPQ).

Design: Electronic databases were searched for papers administering the Brief IPQ published in peer-reviewed journals. Data were extracted from the results for meta-analysis.

Main outcome measures: Use by illness population, country, language and study design. The questionnaire’s concurrent validity, predictive validity, sensitivity to change, discriminant validity and mean scores for different populations were summarised.

Results: The review included 188 papers. The Brief IPQ has been administered to patients from age 8 to over 80, with a wide range of illnesses, in 26 languages from 36 countries. Pooled correlations between illness perceptions and depression, anxiety, blood glucose levels and quality of life were consistent with previous research and theory (range .25–.49 for consequences, identity and emotional representations; ?.12 to ?.27 for personal control). All items were able to predict some outcomes up to one-year follow-up. Each subscale demonstrated sensitivity to change after intervention in randomised controlled trials with the personal control and causal items showing most frequent change.

Conclusions: The Brief IPQ is widely used and has good psychometric properties. More studies should include and analyse the causal item.
