Study population: English speaking adults older than or equal to 55 with a Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV) diagnosis of schizophrenia or schizoaffective disorder that pass a capacity to consent test based on comprehension of the consent form.

Brief summary: Older adults with schizophrenia are a growing segment of the population yet their physical health status is poor. In order to design effective interventions, the contributing factors must be understood. Current data suggest the side effects of psychiatric medications, sociodemographic factors, and health care disparities are a few of the reasons for the poor physical health. There are only limited data on the impact of psychiatric symptomatology and neurocognition on the physical health of this population. These limited data indicate that worse symptomatology and poorer neurocognition may negatively impact physical functioning, a critical component to optimal physical health. The purpose of this pilot study is to begin to fill this knowledge gap by: 1. examining the relationship between neurocognitive function and physical function and 2. Examining the relationship between schizophrenia symptoms and physical function. 3. Examining the relationship between serum Brain Derived Neurotrophic Factor (BDNF) and physical function. Using a descriptive correlational design, 50 older adults (55+) with schizophrenia or schizoaffective disorder will be assessed. Bivariate associations will be used to examine the relationship between key variables including schizophrenia symptoms as measured by the Positive and Negative Syndrome Scale (PANSS), neurocognitive function as measured with the MATRICS Consensus Cognitive Battery (MCCB), Physical Function as measured objectively by the Timed Get Up and Go (TGUG) test and subjectively with the physical component summary subscale of the 12-item short form health survey (SF-12), and serum BDNF. These pilot data will lay the foundation for a future health promoting intervention.
