I am looking at the relationship between Schizophrenia, Substance Abuse and Neurocognition.
I have 30 P's with Schizophrenia and 30 matched-controls (who are matched on age, gender, education level, IQ, and level of substance use), who have been administered a neurocognitive battery of 11 subtests. I want to look at the combined/additive effects of Schizophrenia and Substance Use on Neurocognitive performance.
Unfortunately, due to issues with recruitment and time constraints only small samples sizes could be achieved.
Is it possible to run more complex statistical analyses (other than just correlational analyses), despite the small sample sizes and multiple DV's??
If so, what is recommended to explore this relationship?
