Note: (A) Regression slope of neurocognitive functioning predicting social cognitive functioning; (B) regression slope of social cognitive functioning predicting psychiatric symptoms, controlling for neurocognitive functioning; (C) regression slope of neurocognitive functioning predicting psychiatric symptoms; (C’) regression slope of neurocognitive functioning predicting psychiatric symptoms, controlling for social cognitive functioning. Bootstrapping was used to estimate indirect effects (Shrout & Bolger, 2002).
