Respondent attrition is a common problem in national longitudinal panel surveys. To make full use of the data, weights are provided to account for attrition. Weight adjustments are based on sampling design information and data from the base year; information from subsequent waves is typically not utilized. Alternative methods to address bias from…

Multivariate analysis of variance (MANOVA) is widely used in educational research to compare means on multiple dependent variables across groups. Researchers faced with the problem of missing data often use multiple imputation of values in place of the missing observations. This study compares the performance of 2 methods for combining p values in…

This article examines methodological issues confronting the study of qualitative and quantitative differences in ways that separated parents share time with their children. Measurement issues explored include disentangling dimensions of contact, identifying economic implications of contact, and measuring quality of contact. Sampling issues relate…

Discusses a set of neuropsychodiagnostic rules proposed by Selz and Reitan. That study was found to be seriously limited on theoretical grounds and in terms of research methodology. Sampling problems were indicated, and issues of neurological integrity and learning disabilities were poorly conceptualized. (Author)

Discusses challenges to conducting research on effectiveness of community service systems that are family-based and school-centered: underidentification of children with emotional or behavioral disorders, lack of concordance between diagnostic criteria used in school versus mental health systems, problems of comorbidity, analysis of data from…

This article assimilates and critically reviews 10 reports between 1960 and 1980 in which hypnosis was used with non-retarded children, aged 6 to 17, who had learning problems. Studies are reviewed in terms of the major deficit focused on by the researchers, i.e., reading deficits, self-concept and academic achievement, academic behavior problems,…

This study found that accuracy in predicting the out-of-home placement of children with severe disabilities increased little in a large cross-sectional sample (n=5,992) over a smaller semilongitudinal sample (n=141). Factors such as age, adaptive and maladaptive behavior, and ethnicity are discussed. (Author/JDD)

This survey analyzes the descriptions of research samples provided in 1,353 research articles relating to children. The 1974 volumes of 24 research journals were examined, and all articles in these volumes were included in the survey if they met two criteria: (1) having a research sample, and (2) dealing with children and youth between the…

These three newsletters focus on advances and challenges in disability research. The first issue focuses on the results of a survey that investigated how many consumers with disabilities had a computer available in their home and their Internet use. The study involved administrators of Independent Living Centers (ILC) and ILC consumers. Findings…

Recruiting schools and kids to participate in drug prevention evaluations is no longer, if it ever was, a "done deal." Since the mid-1980s, schools have been inundated with requirements for drug programs and requests to cooperate with program evaluations. As a consequence, both treatment and control schools are harder to find. In addition, many…
