The dimensions of change in therapeutic community treatment instrument

In this article, the authors describe the refinement and preliminary evaluation of the Dimensions of Change in Therapeutic Community Treatment Instrument (DCI), a measure of treatment process. In Study 1, a 99-item DCI, administered to a cross-sectional sample of substance abuse clients (N = 990), was shortened to 54 items on the basis of results from confirmatory factor analyses and item response theory invariance tests. In Study 2, confirmatory factor analyses of the 54-item DCI, completed by a longitudinal cohort of 993 clients, established and validated an 8-factor solution across 2 subpopulations (adults and adolescents) and 2 time points (treatment entry and 30-days postentry). The results of the 2 studies are encouraging and support use of the 54-item DCI as a tool to measure treatment process.     

A privileged and exemplar resource: traumatic avoidance learning and the early triumph of mathematical psychology

The relationship between a classic 1953 study by R. L. Solomon and L.C. Wynne on traumatic avoidance learning adn the pioneering efforts by Robert Bush and Frederick Mosteller and others to develop mathematical models of learning is analyzed. The main purpose is to explore how Bush and Mosteller disembedded a carefully selected set of Solomon and Wynne's data from its original context, which allowed something as seemingly humble as a set of numbers to become a widely available and valuable resource for the newly emerging field of mathematical learning theory (MLT). The creative use that the MLT community made of these data once Bush and Mosteller had systematically reduced the empirical and conceptual uncertainties within Solomon and Wynne's study is also discussed.     

Replicating the five factor model of personality in a psychiatric sample

In this study we examined whether the factor structure and traits of the five-factor model of personality (FFM), derived from non-clinical samples, could be replicated in a sample of psychiatric patients. The revised NEO Personality Inventory (NEO PI-R) was administered to a study group of psychiatric patients (n=176). The test scores from these patients were intercorrelated, factor analyzed and the obtained factor structure was then compared to the factor structure of the normative data from the NEO PI-R. The factor structure from the psychiatric study group and that from the normative sample were virtually identical, with all five factors showing significant congruence. These results argue favorably for the clinical applicability of the FFM with psychiatric patients.     

Habitual Prospective Memory and Aging: Remembering Intentions and Forgetting Actions

Routine or habitual prospective memory tasks (e.g., taking medication) have the potential for creating confusions regarding whether or not an action has already been performed. We developed a laboratory paradigm for examining the kinds of processes thought to be operating in these kinds of tasks. Younger and older participants were asked to perform an action once and only once on each of 11 trials. The results showed that age and divided attention contributed to both omission and repetition errors. This new paradigm reveals memory failures in a habitual prospective memory task, and the results demonstrate that older adults are particularly susceptible to these memory problems.     

A note on "MMPI scale development methodology"

Clopton's recent article (1978) in JPA calls attention to methodological problems in the construction of special inventories from the MMPI pool, but overlooks the major problem. It stems from the theoretical correlation between psychopathology and the construct to be measured by the special inventory. This contamination renders the usual validity demonstration questionable. It is pointed out that there is a good number of special inventories that are not subject to the methodological problems noted by Clopton.     

The status of training in school psychology and trends toward the future

A nation-wide survey was conducted in 1979 to collect information on graduate training in school psychology, including areas of program emphasis and the structure of field training and supervision. Results indicated that the vast majority of programs remain committed to emphasizing the direct service triad of psychoeducational assessment, school consultation, and behavioral intervention, but that two indirect service areas—research and program planning and evaluation—are gaining in training emphasis. It was also found that a very high percentage of programs employ a comprehensive practicum and internship experence, that most placements are in the public schools, and that considerable time is allotted for supervision.     

Memory checklists: A method of teaching functional skills to brain-damaged adults

Three head-injured clients had difficulty performing vocational tasks and routine activities of daily living. Memory checklists, which consisted of a task analysis for each activity, were introduced. All three clients were immediately able to perform the tasks.
