A psychosocial model of sun protection and sunbathing as distinct behaviors was developed on 202 young Caucasian women and replicated in an independent sample (n = 207). Proximal outcomes were intention to sun protect and intention to sunbathe; distal outcomes included sun protection and sunbathing behavior measured 5 months later. Objective risk for skin(More)
1 In the light of continuing debate over the applications of significance testing in psychology journals and following the publication of Cohen’s (1994) article, the Board of Scientific Affairs (BSA) of the American Psychological Association (APA) convened a committee called the Task Force on Statistical Inference (TFSI) whose charge was “to elucidate some(More)
Count data reflect the number of occurrences of a behavior in a fixed period of time (e.g., number of aggressive acts by children during a playground period). In cases in which the outcome variable is a count with a low arithmetic mean (typically < 10), standard ordinary least squares regression may produce biased results. We provide an introduction to(More)
An appearance-based sun-protection intervention program was developed, implemented, and evaluated in a sample of 211 Caucasian women (ages 18-25) randomly assigned to the sun-protection program or to a stress management (control) program. The sun-protection program incorporated a novel construct of image norms of aspirational peers (i.e., female media(More)
OBJECTIVE To document outcomes of a randomized trial of the PhoenixCare demonstration program of palliative care and coordinated care/case management for seriously chronically ill individuals who simultaneously received active treatment from managed care organizations (MCOs). DESIGN Patients, continuously enrolled between July 1999, and March 2001, were(More)
Theories hypothesizing interactions between a categorical and one or more continuous variables are common in personality research. Traditionally, such hypotheses have been tested using nonoptimal adaptations of analysis of variance (ANOVA). This article describes an alternative multiple regression-based approach that has greater power and protects against(More)
The utility of the health belief model (HBM) for predicting compliance with the American Cancer Society recommendations for mammography screening over and above demographics, knowledge, physician input, and objective risk for breast cancer was assessed. In all, 615 predominantly middle-class White women, age 35-92, were surveyed in 1987-1989. A multiple(More)
A multicomponent intervention to increase condom use in sexually active young women was designed, implemented, and evaluated in a randomized experiment. Participants were 198 unmarried female college students (mean age = 18.6 years) who received a 1-session condom promotion intervention or a control (stress management) intervention. The condom promotion(More)
The current investigation examined whether the positive association of family conflict to adolescent depression and conduct problems is attenuated by maternal, paternal, and peer attachment, and maternal and paternal monitoring, within a low-income, multiethnic sample of 284 adolescents. Parental attachment and monitoring moderated the link from family(More)
The relationships of epidemiological (objective) risk indices, perceived disease characteristics, and cognitive heuristics to women's perceived susceptibility to breast cancer, heart disease, and osteoporosis in a community sample of 312 women ages 40-86 were examined. Epidemiological indices accounted for a small to moderate proportion of the variance in(More)
