A short MMPI scale to identify people likely to begin smoking.

An item analysis of the Minnesota Multiphasic Personality Inventory (MMPI) was conducted to develop questionnaires that best discriminated (a) individuals who ever smoked versus those who never smoked and (b) ex-smokers from current smokers. The analyses were based on a sample of subjects who took the MMPI during 1964-1967 and reported their smoking status during 1987. Although no items distinguished individuals who quit versus continued to smoke, several items discriminated people who ever smoked from nonsmokers. These items formed two factors: Extraversion and Unconventionalism. These results provide support for the importance of extraversion, impulsivity, and antisocial tendencies as personality predictors of smoking initiation. The utility of this MMPI scale is discussed.

Age differences in hostility among middle-aged and older adults.

Multiple measures of hostility were administered to middle-aged and older volunteers. There was a positive association between age and self-report measures reflecting hostile beliefs about others, including cynicism and suspiciousness. There was a weak inverse relationship between age and self-report measures of the overt expression of anger and aggression, but no association between age and measures of covert hostility was found. There was a positive relationship between age and an assessment of hostile behavior that was based on the respondent's interaction style during an interview. The magnitude of these age trends did not differ between men (n = 50) and women (n = 75). These findings illustrate the multidimensional nature of hostility. They also have practical implications for older people because hostility is associated with psychological well-being and has been shown to have consequences for health and longevity.

The belief in a just world and perceptions of discrimination.

We examined the relationship between the belief in a just world and frequency of self-reported acts of personal discrimination. American adults with a strong belief in a just world reported fewer acts of personal discrimination against themselves than those with a weak belief in a just world. Among the various domains of discrimination, the belief in a just world correlated most strongly with religious discrimination. People with a strong belief in a just world felt that they would be less likely to provide special programs and funding based solely on a person's age; they did not feel that age discrimination was prevalent in American society.

The impact of abnormal mammograms on psychosocial outcomes and subsequent screening.

Few studies have examined the impact of abnormal mammograms on subsequent mammography screening and psychosocial outcomes specifically as a function of the length of time that has passed since the abnormal test result. This cross-sectional report compared breast cancer screening practices and psychosocial outcomes among three groups of women. These groups were women who (1) never had an abnormal mammogram, (2) had an abnormal mammogram 2 or more years prior to the study's baseline interview, and (3) had an abnormal mammogram within 2 years prior to the study's baseline interview. Women who had an abnormal mammogram at least 2 years prior to the baseline interview expressed greater 10-year and lifetime risks of getting breast cancer than women who never had an abnormal mammogram. Women who had abnormal mammograms, independent of when they occurred, were substantially more worried about getting breast cancer than were women who never had abnormal mammograms. Women who had an abnormal mammogram within 2 years prior to the baseline interview were more likely to be on schedule for mammography, compared with women who never had an abnormal mammogram.

Psychological impact of diagnosis and risk reduction among cancer survivors.

Life-threatening health events prompt psychological distress that may motivate individuals to reduce health risks. If so, interventions timed to take advantage of these 'teachable moments' could be particularly effective. To explore this association, early stage prostate and breast cancer patients were identified from a hospital-based tumor registry within 6 years of diagnosis. These patients (n=920) completed a mailed survey assessing the Horowitz impact of events scale, risk behaviors and readiness to change the behaviors. Breast cancer patients, younger patients and those reporting poor health status reported the greatest impact of the cancer diagnosis. Impact was inversely associated with time from diagnosis for prostate, but not breast cancer patients. Prostate patients who reported exercising regularly had lower impact scores than those who were not exercising (medians: 0.13 vs 0.56, respectively; p=0.02). Breast patients who were eating five or more fruits and vegetables reported lower impact scores than those who were not eating the recommended servings (0.75 vs 1.06, respectively; p=0.03). Breast patients who were non-smokers reported lower impact scores than smokers (0.88 vs 1.31, respectively; p=0. 02). Prospective studies are needed to understand the psychological impact of cancer diagnosis and how it might facilitate or impede the adoption of health promoting behaviors.

Testing different formats for communicating colorectal cancer risk.

This study assessed the extent to which different formats of informing men and women age 50 and over of the risks of colorectal cancer (CRC) affected their perceptions of their absolute and comparative (self versus other) 10-year and lifetime risks; emotional reactions about getting CRC; and screening intentions. Forty-four men and 78 women received information about the absolute lifetime risk of getting CRC. In addition, participants either did or did not receive information about (1) lifetime risk of getting CRC compared with other cancers, and (2) risk factors for CRC (age and polyps). Participants who received risk factors information were more likely to increase their perceived absolute 10-year and lifetime risks of getting CRC compared with participants who did not receive risk factors information. In addition, participants who received risk factors information were more likely to believe age was related to getting CRC and felt at greater risk for having polyps compared with participants who did not receive this information. None of the experimental conditions affected how worried, anxious, and fearful participants felt about getting CRC, nor did they affect screening intentions. Independent of experimental condition, participants tended to increase their intentions to get screened for CRC in the next year or two. Intention to be screened was more pronounced among participants who had been screened via a fecal occult blood test (FOBT) or sigmoidoscopy (SIG). Implications for the design of interventions involving the communication of CRC risks are discussed.

General performance on a numeracy scale among highly educated samples.

BACKGROUND: Numeracy, how facile people are with basic probability and mathematical concepts, is associated with how people perceive health risks. Performance on simple numeracy problems has been poor among populations with little as well as more formal education. Here, we examine how highly educated participants performed on a general and an expanded numeracy scale. The latter was designed within the context of health risks. METHOD: A total of 463 men and women aged 40 and older completed a 3-item general and an expanded 7-item numeracy scale. The expanded scale assessed how well people 1) differentiate and perform simple mathematical operations on risk magnitudes using percentages and proportions, 2) convert percentages to proportions, 3) convert proportions to percentages, and 4) convert probabilities to proportions. RESULTS: On average, 18% and 32% of participants correctly answered all of the general and expanded numeracy scale items, respectively. Approximately 16% to 20% incorrectly answered the most straightforward questions pertaining to risk magnitudes (e.g., Which represents the larger risk: 1%, 5%, or 10%?). A factor analysis revealed that the general and expanded risk numeracy items tapped the construct of global numeracy. CONCLUSIONS: These results suggest that even highly educated participants have difficulty with relatively simple numeracy questions, thus replicating in part earlier studies. The implication is that usual strategies for communicating numerical risk may be flawed. Methods and consequences of communicating health risk information tailored to a person's level of numeracy should be explored further.
