Association of Religious Commitment and Tobacco Use Among Muslim Adolescents

The purpose of this study was to examine the relationship between religious observance and tobacco use among a sample of Jordanian youth. Using multistage, random sampling, a cross-sectional survey of middle and high school students was conducted. Of the 950 Muslim students in the study, 32 % were daily tobacco users and 72 % prayed regularly. Frequency of praying was negatively associated with tobacco smoking. Religious observance was found to be strongly associated with tobacco smoking among Jordanian youth. Our results indicate that religion can be a culturally important tool in health professionals’ efforts for tobacco control.     

Examining legalism,scrupulosity, family perfectionism,and psychological adjustment among LDS individuals

This study examined the relationships and interactions between legalism, scrupulosity, family perfectionism, guilt, and shame among 421 Latter-Day Saints (LDS or Mormons). The results showed that scrupulosity fully mediated the links between legalism and guilt, as well as legalism and shame. A moderated-mediation effect was found, in which family discrepancy (maladaptive perfectionism) intensified the scrupulosity–shame association in the mediation model of legalism and shame by scrupulosity. Family discrepancy was not a significant moderator for the mediation model of legalism and guilt by scrupulosity. Additional results are provided and implications of these findings are outlined.     

Pilot programs in newborn screening

The term "pilot study" has been used over the years to describe the evaluation of the many elements involved in deciding whether a proposed condition should be added to a newborn screening (NBS) panel, and until recently, was unilaterally used to describe the evaluation of the assay to be used before the condition was officially adopted by a state for its newborn screening panel. Since Guthrie's introduction of screening for PKU, each time a new condition was added to the panel, the screening assay itself was validated through a population-based trial, in which the test was performed with de-identified samples to avoid association between the test result and the infant. This is considered by the laboratory as the "pilot phase" of adding a new condition. To advance the science of NBS, especially to accommodate new technologies that may provide new types of information (genetic versus physiological) for each new condition, pilot programs are essential. Involvement of the clinical community serves to improve these evaluations and provides the needed clinical validation of decisions made as a result of it. This paper describes the historical context of pilot programs in population-based NBS that utilize laboratory-based markers as indicators of concern; specifically, three applications that demonstrate different approaches to the use of pilots in adding conditions to a NBS panel are described.     

Resampling probability values for differences between two independent indices of ordinal variation and consensus

A permutation method is presented to calculate resampling probability values for differences between two independent indices of ordinal variation and consensus.     

Exact and resampling probability values for measures associated with ordered r by c contingency tables

Permutation procedures to compute exact and resampling probability values associated with measures of association for ordered r x c contingency tables are described. Comparisons with asymptotic probability values demonstrated that exact and resampling permutation procedures were preferred for sparse contingency tables.     

A measure of effect size for r x c contingency tables

Goodman and Kruskal's tau measure of categorical association is advanced as a replacement for conventional measures of effect size for r x c contingency tables. Goodman and Kruskal's tau is an asymmetric measure of categorical association which is based entirely on the observed data and possesses a clear interpretation in terms of proportional reduction in error. Comparisons with conventional measures of effect size based on chi-squared such as Pearson's phi2, Tschuprow's T2, and Cramer's V2 demonstrate the advantages of employing tau as a measure of effect size.     

Minority students of color and the psychology graduate pipeline: disquieting and encouraging trends, 1989-2003

Trends since 1989 in the minority graduate pipeline in psychology are examined, with special focus on trends in recent years. Encouraging trends generally outweigh troubling ones at lower levels of the pipeline. However, in recent years disquieting trends dominate at the higher pipeline levels. Promising trends include a rise in the percentage (to nearly 25%) of minority psychology students receiving the bachelor's degree and a rise to more than 20% receiving the master's degree. Troubling trends include the stalling of growth in minority PhD degree receipt since 1999 and the lack of growth in the percentage of African American and Hispanic/Latino(a) students entering PhD departments. Given the mixed findings, one of the highest priorities for psychology must be continued and persistent efforts to develop practices and policies that enhance recruitment, high levels of achievement, and degree receipt for students of color.     

Taxometric Investigation of PTSD: data from two nationally representative samples

Current psychiatric nosology depicts posttraumatic stress disorder (PTSD) as a discrete diagnostic category. However, only one study has examined the latent structure of PTSD, and this study suggested that PTSD may be more accurately conceptualized as an extreme reaction to traumatic life events rather than a discrete clinical syndrome. To build on the existing literature base, the present research examined the latent structure of posttraumatic stress reactions by applying three taxometric procedures (MAXEIG, MAMBAC, and L-Mode) to data collected from large nationally representative samples of women (ns = 2684 and 3033) and adolescents (n = 3775). Results consistently provided evidence for a dimensional PTSD solution across samples and statistical procedures. These findings have important implications for the theory, assessment, and investigation of posttraumatic stress reactions.
