Review of Five Instruments for the Assessment of Asperger's Disorder in Adults

Due to the recent inclusion of Aspergers Disorder (AD) in the Diagnostic and Statistical Manual of Mental Disorders (APA, 1994) and the International Classification of Diseases (WHO, 1993), concerns regarding diagnosis of AD, particularly in adults, are emerging. Many existing instruments used to assess Pervasive Developmental Disorder are more appropriate for identifying Autistic Disorder (AU) in children, and their usefulness for assessing AD in adults is questionable. We describe and critically review five instruments created specifically for identifying AD in adults. Overall, the normative information provided is limited and evidence of the reliability and validity for each instrument is relatively poor. Further research and development is required before we would recommend one instrument over another for the assessment of AD in adults.

Development and Preliminary Validation of the Time Management for Exercise Scale

The purpose of this study was to collect preliminary validity evidence for a time management scale for exercise. An initial pool of 91 items was developed from existing literature. Ten exercise/health psychologists evaluated each of the items in terms of relevance and representativeness. Forty-nine items met all criteria. Exploratory factor analysis of the initial pool of items with a sample of 501 undergraduate students revealed an interpretable 32-item, 4-factor solution: exercise importance, exercise documentation, perceived ability to manage time for exercise, and setting exercise goals. Internal consistency values ranged from 0.73 to 0.91. Time management for exercise appears to be related to exercise behavior as indicated by moderate correlations between each of the subscales and exercise behavior.
