The present study utilized a comparative psychotherapy outcome design to evaluate the relative therapeutic efficacy of Christian and secular RET with depressed Christian clients. Results showed both treatments significantly reduced depression, automatic negative thinking, irrational thinking, and general pathology. These gains were maintained after three months. There were no significant differential treatment effects. Results are discussed in terms of the implications for accommodation theory.

Purpose The aims of the study were to investigate the use of semantic associative relationships as primes in treating naming deficits, or anomia, in aphasia and to determine if differential treatment effects would be found if 1 or 3 primes were presented. Method Ten individuals with varying degrees of anomia participated in the study. A single-subject, A-B treatment design with a cross-over component was used. A 1-PRIME condition (use of 1 prime) was compared with a 3-PRIMES condition (use of 3 primes) for each participant. Results Visual analyses of treatment data revealed improvements in 8 of 10 participants. Meaningful effect sizes were obtained in at least 1 of the conditions for 6 of the 10 participants. Slightly more participants demonstrated meaningful effect sizes in the 3-PRIMES condition than in the 1-PRIME condition. Correlation analyses revealed a positive correlation between the number of teaching episodes and 3-PRIMES probe performance. Conclusions The results support a protocol that uses semantic associative primes to increase naming accuracy in aphasia. The 3-PRIMES condition was slightly more beneficial than the 1-PRIME condition in terms of improving naming abilities in these participants, but there was no overwhelming advantage in using one or the other condition.

Post hoc assignment of patterns determined by all pairwise comparisons in microarray experiments with multiple treatments has been proven to be useful in assessing treatment effects. We propose the usage of transitive directed acyclic graphs (tDAG) as the representation of these patterns and show that such representation can be useful in clustering treatment effects, annotating existing clustering methods, and analyzing sample sizes. Advantages of this approach include: (1) unique and descriptive meaning of each cluster in terms of how genes respond to all pairs of treatments; (2) insensitivity of the observed patterns to the number of genes analyzed; and (3) a combinatorial perspective to address the sample size problem by observing the rate of contractible tDAG as the number of replicates increases. The advantages and overall utility of the method in elaborating drug structure activity relationships are exemplified in a controlled study with real and simulated data.
