Evaluated the effects of a theoretically derived program to prevent mental health problems in children who had experienced the death of a parent. The program was designed to improve variables in the family environment which were specified as mediators of the effects of parental death on child mental health. The evaluation design involved the random(More)
Describes a generative study of processes which may lead to symptomatology in children who have experienced the death of a parent. Based on existing literature, four putative mediating variables were identified: parental demoralization, family warmth, negative family events, and positive stable family events. Structural equation modeling techniques were(More)
Prevention programs in mental health theoretically can benefit from selecting participants who have a greater likelihood of developing psychological problems because of their exposure to the putative mediators targeted for change in an intervention. Screening on mediators may increase statistical power to detect program effects, enhance the(More)
Sixty-six patients with amyotrophic lateral sclerosis (ALS) participated in a double-blind, placebo-controlled study of transfer factor. A structured rating score of neurological function was recorded after each monthly administration of transfer factor or placebo. Statistical analysis of mean scores for all patients and for those with specific clinical(More)
Illustrates how standard epidemiologic principles form the knowledge base to justify a preventive intervention for an at-risk population. These principles were applied to a sample of 92 from the population of children aged 8 to 15 at alleged risk for mental health disorders because a parent died. Prior work on this alleged risk population is sparse and(More)
Our comments on the discussion of mediational screening for prevention research highlight two issues: (a) There are advantages to giving a high priority to theory in a strategic sequence of prevention research studies. (b) Screening to identify a subgroup that is experiencing problems on processes the program is designed to change may be useful in(More)
From survey data on 1000 urban Welfare AFDC children aged six to eighteen, a hierarchical cluster analysis yielded six distinct behavioral types of Welfare children. Characteristics of each type, and its relationship to treatment, ethnicity, and other variables are discussed. Advantages of this system of behavioral classification for research and population(More)
