Abstract

Schizophrenia is a neurodevelopmental disorder that is characterized by a number of behavioral abnormalities that are present prior to onset. These premorbid abnormalities may serve as unique markers for the disorder. The current study examines academic and social functioning prior to schizophrenia onset in a group of 58 males diagnosed with schizophrenia. The pattern of deterioration for social and academic functioning was examined across three age periods including childhood, early adolescence, and late adolescence, using the retrospective Premorbid Adjustment Scale (PAS). Results indicated that while increasing deterioration was present for both social and academic adjustment across age periods, there was a significant difference in deterioration between academic and social functioning (p<.05) during late adolescence, with greater deterioration in academic functioning. Results of the current study suggest that premorbid academic functioning is particularly susceptible to deterioration during late adolescence, with accelerating deterioration as schizophrenia onset becomes imminent. When considered together with results from other studies, the present findings suggest that deterioration in premorbid academic functioning from early to late adolescence may be a unique premorbid marker for schizophrenia.
