ABSTRACT
Traditional approaches to diagnosing autism emphasize delays in communication and socialization. Traditional diagnostic schemes typically list symptoms (e.g., lack of eye contact), but provide little guidance on how to incorporate information about developmental level in making a diagnosis. Because standardized measures of adaptive behavior can provide information about children's communication, socialization, and other behavior relative to their age, they may be useful tools for diagnosing autism. This study investigated the ability of the Vineland Adaptive Behavior Scales to identify children with autism. Vineland scores and measures of intellectual functioning were obtained for children with autism, PDDNOS, and other developmental disorders (DD). Discriminant function analyses indicated that the autism and combined nonautism (PDDNOS and DD) groups could be differentiated on the basis of socialization, daily living skills, and serious maladaptive behaviors. Socialization alone accounted for 48% of the variance in diagnosis. Using regression analyses derived from a large normative sample, adaptive behavior scores were predicted from chronological age (CA) and mental age (MA). Socialization scores in the autism group were substantially below the level predicted from CA or MA. An index derived from the ratio of actual to predicted socialization scores correctly classified 86% of both autism and nonautism cases. Findings suggest that comparison of obtained Vineland socialization scores to those predicted by CA or MA may be useful in clarifying the diagnosis of autism.

We have argued that psychology as a field has been preoccupied with the negative side of life and has left us with a view of human qualities that is warped and one-sided. Psychology is literally 'half-baked'. We need to bake the other half now. It is time for us to become equally concerned with the qualities and experiences that make life most worthwhile. A balance is needed between work that strives to relieve damage and work that endeavors to build strength. This balance is beautifully exemplified by Jack Rachman's work over the past 40 years. As an astute and compassionate clinician and researcher, Jack developed and evaluated effective treatments for some of the most debilitating anxiety disorders. At the same time, he was impressed by the resiliency of his clients and the courage they exhibited daily. His observations and studies of courage have helped to launch a systematic science of human strengths. They are giant footsteps on the road to a positive psychology.
