Daily Behavior Report Cards with and without Home-Based Consequences: Improving Classroom Behavior in Low Income,African American Children with ADHD

Daily Behavior Report Cards (DBRC), which typically require teachers to evaluate students' daily behavior and parents to provide contingent consequences, are an effective and acceptable method for improving children's classroom behavior. The current study evaluated whether parent involvement is an essential treatment component or whether teacher feedback alone would be sufficient to produce children's behavior changes. The effectiveness of DBRC with teacher feedback to students and parent delivered consequences (PC) was compared to teacher feedback to students only (no parent delivered consequences, NPC) for increasing appropriate classroom behavior and academic productivity in African American, low income, elementary school children with Attention-Deficit/Hyperactivity Disorder (ADHD). Both treatments led to increased on-task behavior, although PC was superior to NPC. Academic productivity outcomes are less clear. Treatment implications and future directions for research on teacher feedback interventions are discussed.     

Doing Well: A SEM Analysis of the Relationships Between Various Activities of Daily Living and Geriatric Well-Being

An existing large data set, the Health and Retirement Study (HRS) with the subsequent addition of the Consumption and Activities Mail Survey (CAMS) data, provides a rich data set for the examination of the activities of older adults. In this study HRS and CAMS data are used to examine relationships between various activities of daily living (ADLs) and well-being in older adults. Using structural equation modeling, influences of direct and indirect factors that affect older individuals' cognitive and emotional well-being are analyzed. The data suggest ability to perform ADLs has little to do with cognitive well-being, but is an influential factor in determining emotional well-being.     

Accuracy of Effect Size Estimates From Published Psychological Experiments Involving Multiple Trials

The reporting of exaggerated effect size estimates may occur either through researchers accepting statistically significant results when power is inadequate and/or from repeated measures approaches aggregating, averaging multiple items, or multiple trials. Monte-Carlo simulations with input of a small, medium, or large effect size were conducted on multiple items or trials that were either averaged or aggregated to create a single dependent measure. Alpha was set at the .05 level, and the trials were assessed over item or trial correlations ranging from 0 to 1. Simulations showed a large increase in observed effect size averages and the power to accept these estimates as statistically significant increased over numbers of trials or items. Overestimation effects were mitigated as correlations between trials increased but still remained substantial in some cases. The implications of these findings for meta-analyses and different research scenarios are discussed.     

The effects of clinical motor variables and medication dosage on working memory in Parkinson’s disease

In this study, we investigate the interrelationship between clinical variables and working memory (WM) in Parkinson’s disease (PD). Specifically, the aim of the study was to investigate the relationship between disease duration, dopaminergic medication dosage, and motor disability (UPDRS score) with WM in individuals with PD. Accordingly, we recruited three groups of subjects: unmedicated PD patients, medicated PD patients, and healthy controls. All subjects were tested on three WM tasks: short-delay WM, long-delay WM, and the n-back task. Further, PD encompasses a spectrum that can be classified either into akinesia/rigidity or resting tremor as the predominant motor presentation of the disease. In addition to studying medication effects, we tested WM performance in tremor-dominant and akinesia-dominant patients. We further correlated WM performance with disease duration and medication dosage. We found no difference between medicated and unmedicated patients in the short-delay WM task, but medicated patients outperformed unmedicated patients in the long-delay WM and n-back tasks. Interestingly, we also found that akinesia-dominant patients were more impaired than tremor-dominant patients at various WM measures, which is in agreement with prior studies of the relationship between akinesia symptom and basal ganglia dysfunction. Moreover, the results show that disease duration inversely correlates with more demanding WM tasks (long-delay WM and n-back tasks), but medication dosage positively correlates with demanding WM performance. In sum, our results show that WM impairment in PD patients depend on cognitive domain (simple vs. demanding WM task), subtype of PD patients (tremor- vs. akinesia-dominant), as well as disease duration and medication dosage. Our results have implications for the interrelationship between motor and cognitive processes in PD, and for understanding the role of cognitive training in treating motor symptoms in PD.     

Developmental changes in coping: Situational and methodological influences

Abstract

Previous studies on the development of coping have shown rather inconsistent findings regarding the developmental trajectories for different coping dimensions. The aim of this study is to search for possible influences that might explain these inconsistencies. The analysis focuses on methodological influences (longitudinal vs. cross-sectional assessments) and situational influences. Two samples of children were traced longitudinally with yearly assessments from grade 2 to 5 (sample 1, N =432) and from grade 4 to 7 (sample 2, N =366). A third sample (N =849) was added with cross-sectional assessments from grade 2 to 7. The assessed coping dimensions were related to (a) problem solving, (b) seeking social support, (c) palliative coping, (d) externalizing emotional coping, and (e) avoidant coping. The use of the coping strategies had to be assessed for six stress-evoking situations. The results show only small differences between the longitudinal and the cross-sectional coping assessments. There are, however, clear situational influences on the choice of the coping strategies and also on the resulting developmental trajectories.     

Reflections On The Intensive Measurement Of Stress,Coping, And Mood,With An Emphasis On Daily Measures

Abstract

This paper discusses reasons for the shift from longer-term measurement of stress, coping, and mood to more intensive measurement strategies. Daily assessments are common in intensive studies of these constructs. We review measures available to the researcher, focusing on various aspects of the constructs. While daily assessments are an improvement over less intensive methods, we also discuss shortcomings of these measures. Furthermore, current assessments may not capture many important dimensions of stressful occurrences, and we suggest that such occurrences be thought of in terms of episodes. Modifications of current assessments are discussed, as are even more intensive assessments of stress, coping, and mood.     

The Impact of the United States Air Force Deployment Transition Center on Postdeployment Mental Health Outcomes

The United States Air Force Deployment Transition Center (DTC) operates a 2-day third-location decompression program that commenced operations during the summer of 2010 in Ramstein, Germany, with the aim to assist Air Force service members (AFSMs) who are returning from deployment as they prepare to reintegrate back into their home lives and work stations. The present study evaluated the impact of DTC attendance on later mental health outcomes. Because participants are not randomly assigned to attend the DTC, propensity score weighting was used to compare DTC participants (N = 1,573) to a weighted control group of AFSMs (N = 1,570) in the same job specialties who returned from deployment during the same time period. Rates of endorsement to items on the Postdeployment Health Reassessment were examined and compared, as were rates of mental health diagnoses from AFSMs’ official medical records. Key findings indicate that DTC participants reported lower levels of depressive and posttraumatic stress symptoms and lower levels of relationship conflict following return from deployment, as compared to weighted control participants. Mental health diagnostic rates were comparable for the 2 groups during the first 6 months following return from deployment. These findings suggest that participation in the DTC program had notable benefits for redeploying AFSMs and support the continued use of the program.
