A randomized trial of a representational intervention to decrease cancer pain (RIDcancerPain).

OBJECTIVE: Based on theories regarding cognitive representations of illness and processes of conceptual change, a representational intervention to decrease cancer pain (RIDcancerPain) was developed and its efficacy tested. DESIGN: A two-group RCT (RIDcancerPain versus control) with outcome and mediating variables assessed at baseline (T1) and 1 and 2 months later (T2 and T3). Subjects were 176 adults with pain related to metastatic cancer. MAIN OUTCOME MEASURES: Outcome variables were two pain severity measures (BPI and TPQM), pain interference with life, and overall quality of life. Mediating variables were attitudinal barriers to pain management and coping (medication use). RESULTS: One hundred and fifty subjects completed the study. Subjects in RIDcancerPain (T1-T2 and T1-T3) showed greater decreases in Barrier scores than those in control. Subjects in RIDcancerPain (T1-T3) showed greater decreases in pain severity than those in control. Change in Barriers scores mediated the effect of RIDcancerPain on pain severity. CONCLUSION: RIDcancerPain was efficacious with respect to some outcomes. Further work is needed to strengthen it.

Social Capital, Social Networks, and Political Participation

Social Capital is created through the patterns of interdependence andsocial interaction that occur within a population, and we attempt to understand the participatory consequences of these patterns relative to the effects of human capital and organizational involvement. The production of social capital in personal networks was examined with the use of social network and participation data from the 1992 American study of the Cross National Election Project. The results suggest that politically relevant social capital (that is, social capital that facilitates political engagement) is generated in personal networks, that it is a by-product of the social interactions with a citizen's discussants, and that increasing levels of politically relevant social capital enhance the likelihood that a citizen will be engaged in politics. Further, the production of politically relevant social capital is a function of the political expertise within an individual's network of relations, the frequency of political interaction within the network, and the size or extensiveness of the network. These results are sustained even while taking account of a person's individual characteristics and organizational involvement. Hence, the consequences of social relations within networks are not readily explained away on the basis of either human capital effects or the effects of organizational engagement.     

Enrichment and Stress in Families Caring for a Child with a Serious Emotional Disorder

We examined enrichment and stress in 214 families who had children with severe emotional disorders. Caregivers' ratings of enrichment and stress were obtained through a newly developed instrument, the Effects of the Situation Questionnaire, which used parallel items covering 17 life areas. While ratings of stress were generally higher than enrichment, caregivers reported some enrichment in areas encompassing self concept and family relationships, Bivariate and multivariate analyses using various child, family, and service-system variables revealed that stress was notably associated with severity of the child's disorder, low empowerment, and a lack of coordination among service providers. Enrichment was unrelated to severity but associated with high empowerment and spiritual support. Our findings suggest that families' experiences of caregiving can have both positive and negative aspects and that a comprehensive approach to serving and studying families should take both into account.     

Some cautions regarding statistical power in split-plot designs

We show that if overall sample size and effect size are held constant, the power of theF test for a one-way analysis of variance decreases dramatically as the number of groups increases. This reduction in power is even greater when the groups added to the design do not produce treatment effects. If a second independent variable is added to the design, either a split-plot or a completely randomized design may be employed. For the split-plot design, we show that the power of theF test on the betweengroups factor decreases as the correlation across the levels of the within-groups factor increases. The attenuation in between-groups power becomes more pronounced as the number of levels of the withingroups factor increases. Sample size and total cost calculations are required to determine whether the split-plot or completely randomized design is more efficient in a particular application. The outcome hinges on the cost of obtaining (or recruiting) a single subject relative to the cost of obtaining a single observation: We call this thesubject-to-observation cost (SOC) ratio. Split-plot designs are less costly than completely randomized designs only when the SOC ratio is high, the correlation across the levels of the within-groups factor is low, and the number of such levels is small.     

The accuracy of four approximations to noncentralF

The accuracy of the two-moment, three-moment, square root, and cube root approximations to the noncentralF distribution was assessed using 7,920 entries from Tiku’s (1967) power tables. Tiku’s tables list exact values of β for α= .005?.05, ν₁ = 1?12, ν₂ = 2?120, and ?= 0.5?3.0. Analysis of the errors showed generally satisfactory performance for all four approximations. The three-moment approximation was most accurate, registering a maximum error of only .009. The other three approximations had maximum errors of ±.02, except for the square root approximation at ν₂ = 2, where maximum errors of .05 occur. Approximation error increased with decreases in ν₁ and, less consistently, with increases in ν2. Error was nonmonotonically related to ?. A second investigation explored the accuracy of the approximations at values of αranging from .10 to .90. All four approximations degraded substantially in this situation, with maximum errors ranging from ?.09 to .05. If the analysis is restricted to cases where ν₁ τ; 1 and ν₂ τ; 2, maximum errors drop to roughly ±.03. We conclude that the approximations perform reasonably well for small αand moderately well for larger values, if certain restrictions are imposed. From a computational standpoint, however, there is little advantage to using approximate as opposed to exact methods unless exact values ofF _α are known in advance.     

Reflections on Israel Scheffler's Philosophy of Religion

The burden of this piece is to draw together into a coherent whole the somewhat diverse strands of Israel Scheffler's thought on the philosophy of religion. Extrapolating from personal discussions with Professor Scheffler, various of his books, articles, and other unpublished materials authored and kindly provided by him, I contend that he adumbrates a post-empiricist rendering of religious belief which masterfully avoids some philosophical problems, while unwittingly giving rise to others. Committed to the view that the methodology of science – in one or other of its more acceptable guises – provides the most reliable measure of the content and structure of reality. Scheffler is bound conceptually to redefine Jewish belief in such a way that the traditional conflict between religion and science never emerges. Consistent with this end, he is concerned to divest traditional Judaism of its metaphysical garb, so that what remains are simply the matters of living to which religion ought properly on his view address itself. The Bible is thus reconceptualized as a piece of rich literature, of no real difference in logical kind to any other piece of rich literature, except that it defines uniquely, along with the Torah and other relevant Jewish literature, the history of the particular community whose perception of human values and meaningfulness forms the core of what it is to be Jewish.While I have no quibble whatsoever with Scheffler that the Bible and other religious teachings provides a profound reservoir for cognitive insight into the matters of quality living and appropriate social interaction, I argue that the divorce of religious values from the metaphysics of religion is in the end misguided. My problem with Scheffler's philosophy of religion is not so much with what he has found to be central to religion, as what he has failed to find in religion. By jettisoning its metaphysical basis, he has jettisoned what is inevitably fundamental to Judaism – namely, a resolute belief in God. This being so, an atheist could more readily adopt Scheffler's version of Judaism than could the theist – an outocme which should be problematic for both the theist and the atheist.     

Teacher race,student race,and the behavior problem checklist

The ratings of 458 fourth- and fifth-grade boys were investigated to determine whether or not scores on the Behavior Problem Checklist vary systematically with teacher or student race. Analyses of the data for conduct problems, inadequacyimmaturity, and socialized delinquency indicated that white teachers demonstrate a strong tendency to rate black children as more deviant and white children as less deviant when contrasted with the ratings of black teachers. The ratings of black teachers were found not to vary with student race. No differences among any of the variables were found with regard to personality problems. Possible explanations for the results are discussed, along with implications for the use of the Behavior Problem Checklist in the field.
