Reliability of interview-assessed hostility ratings across mode of assessment and time.

These studies addressed 2 questions concerning interview-based hostility assessments: whether they are affected if the interview is conducted face-to-face versus telephone and whether they are stable across an extended time period. In Study 1A, 54 students were interviewed face-to-face and by telephone in a laboratory setting. Half the sample was reinterviewed in the laboratory 6 weeks later. The other half was reinterviewed by telephone at home. With 1 exception, all intraclass correlation coefficients (ICCs) comparing interview modes were above .62. In Study 1B, 48 adults were interviewed face-to-face in a laboratory and by telephone in their homes with a 2-week intervening interval. The ICC comparing interview modes was .78. In Study 2, 100 adults were interviewed face-to-face in a laboratory and approximately 4 years later by telephone in their homes. The ICC across interviews was .69. Thus, support was found for the stability of interview-based hostility assessments across interview methods and extended periods of time.

Hostility predicts magnitude and duration of blood pressure response to anger.

The hypothesis that hostile and nonhostile individuals would differ in both magnitude and duration of cardiovascular reactivity to relived anger was tested. Participants were 66 older adults (mean age, 62; 38 women and 28 men; 70% Caucasian American, 30% African American). Each took part in a structured interview scored using the Interpersonal Hostility Assessment Technique. Later each relived a self-chosen anger memory while heart rate and systolic and diastolic blood pressures were measured continuously using an Ohmeda Finapres monitor. Hostile participants had larger and longer-lasting blood pressure responses to anger. African Americans also showed longer-lasting blood pressure reactivity to anger. Health and measurement implications are discussed.

Measures of hostility as predictors of facial affect during social interaction: evidence for construct validity.

We assessed the construct validity of several self-report measures and an interview-based measure of hostility (Interpersonal Hostility Assessment Technique [IHAT]) by evaluating their associations with a behavioral indicator of hostile emotions (facial expressions during social interaction). Participants in the study were 123 volunteers (44% males and 56% females) who were recruited from local community organizations. Self-report measures (Cook-Medley Hostility Scale, Rotter Interpersonal Trust Scale, Buss-Durkee Hostility Inventory, and Spielberger Anger Expression Scale) were represented by factor scores reflecting Overt Hostility, Covert Hostility, and Hostile Beliefs. A canonical correlation analysis identified significant associations between a set of facial affect scores reflecting animosity and various measures of hostility. Specifically, increases in anger and disgust expressions and decreases in happy facial expressions were associated with high IHAT scores and high scores on self-report measures of Hostile Beliefs and Covert Hostility. Women were more expressive than men, especially concerning positive affect, and women had lower scores on self-report measures of Hostile Beliefs and Overt Hostility. IHAT scores were uncorrelated with any of the self-report factors which suggests the two assessment techniques are tapping different aspects of the hostility construct.

Trust, health, and longevity.

Scores on the Rotter Interpersonal Trust Scale were evaluated as predictors of psychological well-being, functional health, and longevity in a sample of 100 men and women who were between 55 and 80 years old at baseline (mean age 66.8). Cross-sectionally, high levels of trust were associated with better self-rated health and more life satisfaction. Follow-up over approximately 8 years found baseline levels of trust to be positively related to subsequent functional health, but not to subsequent life satisfaction. Mortality follow-up after 14 years demonstrated that those with high levels of trust had longer survival (p = .03), a finding that was somewhat weakened by controlling for baseline health ratings. These findings illustrate the health protective effects of high levels of trust and suggest the potential usefulness of the trust concept for understanding successful aging.

Personality factors differentially predict exercise behavior in men and women.

Personality assessed with the Minnesota Multiphasic Personality Inventory (MMPI) in college was used to predict exercise behavior measured at midlife in 3,630 men and 796 women enrolled in the University of North Carolina Alumni Heart Study. Logistic regression models were fitted for each of the MMPI clinical scales to test the predictive effect of personality, gender, and their interaction on adult exercise behavior. Lower depression, social introversion, and psychopathic deviance scores were associated with increased probability of exercising in midlife for both men and women. Furthermore, better psychological health (indexed by lower hypochondriases and psychasthenia) in college was generally predictive of increased exercise for men, whereas higher scores on these same factors predicted midlife exercise for women. There were two other patterns of gender interactions: (a) for men, lower scores on hysteria and schizophrenia scales were associated with increased probability of exercising at midlife, whereas these factors were unrelated to exercise for women and (b) for women, lower ego strength and higher college scores on paranoia and mania were associated with exercise behavior at midlife. These data suggest that early adulthood personality predictors of exercise behavior at midlife are both gender-neutral and gender-specific; that is, where no gender differences exist, healthier personality traits predict exercise at midlife, and when gender differences do occur, healthier college patterns of personality predict exercise behavior for men and sedentary behavior for women.

Interpersonal Hostility Assessment Technique: description and validation against the criterion of coronary artery disease.

High levels of hostility are associated with adverse health outcomes. The Interpersonal Hostility Assessment Technique (IHAT; Barefoot, 1992) measures hostility from verbal behavior during a standardized interview. Four types of behaviors are scored as hostility: evading the question, irritation, and indirect and direct challenges to the interviewer. The sum of the frequencies of these acts is a Hostile Behavior Index (HBI), which is divided into two components: verbal, scored with speech content in mind, and paraverbal, based on vocal stylistics. This study examined characteristics of IHAT assessments in 129 male coronary patients. Satisfactory interrater reliabilities were obtained. The HBI correlated highly (.58) with coronary artery disease severity after controlling for traditional risk factors. This relation was not affected by question topic or by differential weighting of the four hostile behaviors. Both HBI components were significantly correlated with disease. Results are discussed in terms of their implications for hostility assessment.
