Factors That Influence Personal Perceptions of the Risk of an Acute Myocardial Infarction
Personal risk perceptions of acute myocardial infarction (AMI) affect people's preventive health behaviors as well as their beliefs during a heart attack episode. The authors investigated factors that are associated with personal risk perceptions of having an AMI. A random-digit-dial survey was conducted among 1294 respondents, aged 18 years or older, in 20 communities across the nation as part of the Rapid Early Action for Coronary Treatment (RE…
Mammography use among sociodemographically diverse women: The accuracy of self-report
OBJECTIVE. This study sought to determine the accuracy of self-report of mammography experience among 392 ethnically diverse women aged 50 to 74. METHODS. Subjects were randomized to the telephone or mail condition and surveyed. RESULTS. Thirty-one percent of women reported accurately the exact month and year of their most recent mammogram; 54% reported accurately within +/- 3 months, and 83% reported accurately within the year. Greater accuracy …

Behavioral outcomes of Aids educational interventions for drug users in short-term treatment
This paper reports the behavioral outcomes of informational vs enhanced small-group educational interventions for drug users among 407 subjects in a short-term drug treatment program. Logistic regression was used to analyze drug use and sexual behaviors at the final follow-up visit. Among lower risk subjects, the enhanced intervention was more effective in reducing injection practices that produced risks in terms of human immunodeficiency virus i…
Aids education for drug abusers: Evaluation of short-term effectiveness
BACKGROUND. Interventions are needed to assist drug abusers in reducing risky drug and sexual behavior. METHODS. A randomized controlled trial compared three small-group AIDS educational interventions among 567 clients of a 21-day inpatient drug detoxification program: a two-session informational intervention, given either during the first (early) or second (late) week of treatment; and a six-session enhanced intervention. Changes in knowledge, a…
Changes in mammography use: Economic, need, and service factors
OBJECTIVES. The purpose of this study was to document changes in mammography use between 1987 and 1990 and assess the relationship of use to selected economic, need, and health system factors. METHODS. Independent random-digit-dialed telephone surveys of women between 52 and 75 years of age were conducted. RESULTS. Between 1987 and 1990, the proportion of women who had had a mammogram in the past year increased from 31% to 51%. Though income was …
Breast cancer screening by mammography: Utilization and associated factors
The status of mammography screening experience and factors related to utilization were examined in six towns serviced by physician staffs at five hospitals. Data were collected via random digit dial telephone interview of a probability sample of 1184 women, aged 45-75 years. The results showed that 55% of the women reported ever having had a mammogram. Of those who had ever had a mammogram, 21% reported that the mammogram in the past year was the…
Effects of HIV antibody test knowledge on subsequent sexual behaviors in a cohort of homosexually active men
This study assesses the effects of HIV (human immunodeficiency virus) antibody testing on subsequent (one year) sexual behavior among 270 homosexual men at a Boston community health center, 21 per cent of whom were unaware of their test result. Except for the number of steady partners, the levels of all sexual activities of all groups of study participants declined over time. No effects of test awareness of antibody status were found on protectiv…
Improving frequency and proficiency of breast self-examination: Effectiveness of an education program
A randomized trial to improve breast self-examination (BSE) performance among college-age women was developed and results evaluated at a large public university. The major intervention was a BSE group education session conducted in classroom and workshop settings. The pre-intervention and six-months-after experimental-control comparisons show that: current performance of BSE increased by 26 per cent, bi-monthly or more often BSE performance incre…
Self care for colds: A cost-effective alternative to upper respiratory infection management
A Cold Self-Care (CSC) Center was established in a prepaid ambulatory care setting serving 21,500 subscribers and their dependents. After CSC establishment, a decrease in visits to practitioners for common colds was demonstrated. The operating cost ratio of an outpatient visit as compared to a CSC visit was 14.7/1. Savings over a two-year period are estimated at over $46,000, representing an average estimated ratio of $.09 cost per dollar saved p…
