The present report provides a summary of five studies undertaken to develop a French-language instrument to assess cohesiveness in sport teams—the “Questionnaire sur l’Ambiance du Groupe” (QAG). For the initial version of the instrument, the Group Environment Questionnaire (Carron, Widmeyer, & Brawley, 1985) was translated into French using the protocol outlined by Vallerand (1989). However, psychometric analyses undertaken in Studies 1, 2, and 3 failed to yield acceptable evidence of construct validity. Items were then revised in an attempt to make them more suitable for the French culture. Subsequent analyses in Study 4 provided support for the construct validity and reliability (internal consistency and interscale equivalence) of the QAG. In Study 5, predictive validity was demonstrated. The QAG has been found to possess satisfactory psychometric properties as a measure of cohesion in sport teams.

AbstractPrevious studies show that MS patients take longer than healthy controls to plan their solutions to Tower of London (TOL) problems but yield conflicting results regarding the quality of their solutions. The present study evaluated performance under untimed or timed conditions to assess the possibility that differences in planning ability only occur when restrictions in solution times are imposed. MS patients (n = 39) and healthy controls (n = 43) completed a computerized version of the TOL under one of two conditions. In the untimed condition, participants were allowed as much time as needed on each problem. In the timed condition, limits were imposed on solution times and time remaining was displayed with each problem. Patients exhibited longer planning times than controls, and the disparity between groups increased with problem difficulty. Planning performance depended upon condition. In the untimed condition, patients and controls performed equally well. When solution times were restricted, however, patients solved fewer problems than controls. MS patients’ planning ability is intact when permitted sufficient time to formulate the required plan. Deficiencies in planning are only evident when time is restricted, and, therefore, are more accurately considered a relative consequence of disease-related problems in information processing speed.

ABSTRACT Alzheimer's disease (AD) is associated with progressive impairment of higher-level cognitive abilities. Previous research suggests that early impairment of executive functions occurs during the course of the disease, but few studies have specifically investigated planning ability in an AD population. Objective: The purpose of the current study was to examine whether AD patients retain the ability to plan ahead, by analyzing specificities of their behavior in successfully achieving a pre-established goal. Methods: Twenty-one AD patients and thirty-three elderly controls underwent a problem-solving assessment using the Tower of London (TOL) test. Results: AD patients were less accurate and less efficient than controls. AD patients also committed more mistakes. This indicates a decline in working memory and inhibitory deficits, resulting in impulsive and inappropriate behaviors. Conclusion: These results are in agreement with previous studies, showing executive function problems in patients with AD. Specifically, this study demonstrates the presence of planning ability deficits in AD, considering both qualitative and quantitative approaches. The wide range of analysis presented in this study can aid clinicians in identifying the nature of the poor performance of AD patients during a planning task.

Planning ability is important in everyday functioning, and a key measure to assess the preparation and execution of plans is the Tower of London (ToL) task. Previous studies indicate that older adults are often less accurate than the young on the ToL and that there may be cultural differences in performance on the task. However, potential interactions between age and culture have not previously been explored. In the current study we examined the effects of age on ToL performance in an Asian culture (Malaysia) and a Western culture (British) (n = 191). We also explored whether working memory, age, education, and socioeconomic status explained variance in ToL performance across these two cultures. Results indicated that age effects on ToL performance were greater in the Malaysian sample. Subsequent moderated mediation analysis revealed differences between the two cultures (British vs Malaysians), in that the age-related variance in ToL accuracy was accounted for by WM capacity at low and medium education levels only in the Malaysian sample. Demographic variables could not explain additional variance in ToL speed or accuracy. These results may reflect cultural differences in the familiarity and cognitive load of carrying out complex planning tasks.

This paper describes the initial steps toward the construction of an experimental, multidimensional inventory to - measure reactions to physical disability. The Relations to Impairment and Disability Inventory (RIDI) was developed to provide information on eight patterns of psychosocial reactions to disability, namely: shock, anxiety, denial, depression, internalized anger, externalized hostility, acknowledgement, and adjustment. Data are presented on initial psychometric analyses of the inventory. Analyses of the eight scales supported their homogeneity and relative independence, and the inventory's construct validity was partially documented. A moderately high degree of relationship was found between the Acknowledgement and Adjustment scales and the Acceptance of Disability (AD) scale (Linkowski, 1971), providing partial support of the inventory's criterion-related validity.
