Objective: This research examined why smokers receiving combination medication for smoking cessation are more likely to quit smoking than are those who receive either single agent (monotherapy) or placebo. Method: Data were collected from 1,504 current smokers (58.2% women, 83.9% White; mean age = 44.67 years, SD = 11.08) participating in a…

Objective:This report extends earlier accounts by addressing the effects of the Strong African American Families (SAAF) program across 65 months. Two hypotheses were tested: (a) Rural African American youths randomly assigned to participate in SAAF would demonstrate lower rates of alcohol use than would control youths more than 5 years later, and…

Explores usefulness of a two-stage diagnostic system. The proposed diagnostic system warrants trail application in a real-life setting, although 85 percent of the initially unclassified subjects and 79 percent of the random data records were also identified. (Author)

Examined the discriminant validity, criterion-related validity, and between-spouse agreement for a marital intake interview as a function of interview method and valence of interview items. Results suggested a high degree of discriminant validity, higher interspouse correlations during joint interviews, and higher indices of criterion related…

Investigators are urged to plan factor analytic studies prior to collecting the data, to formulate a hypothesized factor structure, to develop several relatively pure measures of each factor expected, and to select an appropriate sample of at least 200 cases. Continuous variables should be used rather than dichotomous variables. (Author)

Examined the reliability of spouses as observers of the behaviors that occur in their own marital relationships. Distressed and nondistressed couples collected data in the home. Across the entire checklist, nondistressed couples exhibited significantly greater consensus than did distressed couples, based on both percentage agreement and kappa.…

Symptom scales were developed for three parallel symptom checklists for three types of informants used in diagnostic evaluation. These scales were designed to maximize the comparability of data across informants without sacrificing the distinctiveness of different evaluators' frames of reference. Cluster analyses of checklists yielded nine…
