The cardiac anxiety questionnaire: development and preliminary validity.

Heart-focused anxiety (HFA) is the fear of cardiac-related stimuli and sensations because of their perceived negative consequences. Although HFA is common to a wide variety of persons who experience chest pain and distress, it often is unrecognized and misdiagnosed, particularly in cardiology and emergency room patients without and with heart disease. To address these concerns, this article reports on the development and preliminary psychometric evaluation of the Cardiac Anxiety Questionnaire (CAQ) designed to measure HFA. In Study 1, 188 cardiology patients completed the CAQ. Item and factor analyses indicated a three-factor solution pertaining to heart-related fear, avoidance, and attention. Reliability analysis of the 18-item CAQ revealed good internal consistency of the total and subscale scores. In Study 2, 42 patients completed the CAQ and several other anxiety-related questionnaires to assess its convergent and divergent properties. Although preliminary validity results are promising, further psychometric study is necessary to cross-validate the CAQ, examine its test-retest reliability, and confirm the stability of the factor structure. Taken together, the CAQ appears to assess HFA, and may therefore be a useful instrument for identifying patients with elevated HFA without and with heart disease.

What is a binge? The influence of amount, duration, and loss of control criteria on judgments of binge eating.

OBJECTIVE: We investigated the influence of amount of food eaten, duration of eating episode, and loss of control in judgments of eating episodes as binges. METHOD: Participants rated the degree to which the eating behavior of a female actress qualified as a "binge" after observing eight videotaped vignettes in which the amount of food eaten, apparent duration of eating episode, and loss of control were varied. Binge ratings were stable across a test-retest interval of 3-4 weeks, there was minimal observer drift, and the experimental variables were independently perceived. RESULTS: A repeated measures analysis of variance (ANOVA) on binge ratings revealed significant main effects for quantity and loss of control, and a significant Quantity x Time interaction. DISCUSSION: The results are consistent with the definitional criteria of a binge, underscore the independence of loss of control, and highlight the importance of the violation of dietary standards in judgments of binges. Moreover, they illustrate the reliability and sensitivity of the methodology, and its potential for further investigations of binge eating.

Psychophysiological and MMPI personality assessment of headaches: an integrative approach.

Multiple psychophysiological measures and personality assessment techniques were combined to facilitate the diagnosis of headache type and improve upon existing methodology. Twenty-four migraine, 24 chronic tension headache patients, and 24 normal age- and gender-matched controls were assessed with bilateral measures of frontalis and occipitalis EMG and blood volume pulse. All subjects completed the MMPI. Results suggest that headache subjects could be differentiated on baseline heart rates and MMPI scales 1,2,3, and 7. Only one physiological measure served as an index of psychological distress, suggesting issues of an interaction between psychophysiological and personality variables, as well as the chronicity of the headache.
