Abstract
This project is preliminary attempt to investigate the validity of an original biopsychosocial model of abnormal movement disorders in chronically mentally ill psychiatric inpatients. The model unites evidence that abnormal movements can limit social support, that stress can exacerbate abnormal movements, and that social support can mitigate the effects of stress. As a part of an overarching Illinois Department of Mental Health study of a state psychiatric hospital closure, detailed and comprehensive psychosocial data were gathered on 57 subjects. Tests of group differences between subjects with and without abnormal movements show significant differences in levels of stress, social support, social interaction, and social acceptability. Additionally, severity of abnormal movements correlates with continuous measures of these psychosocial variables. Lastly, logistic regression modeling shows that psychosocial variables, in addition to biological variables, contribute unique explanatory power to a model of presence or absence of abnormal movements. These results support the predictions of the model, which suggests that abnormal movements, especially those of the face, alienate potential sources of social support. With the reduction of this protective social buffer, life stress can have an unmitigated, detrimental effect on the severity of abnormal movements.
