Analysis of Avoidant Quantitative Dimensional Scores as a Predictor of Performance on the SPAN, 3–7 CPT, and TMT-B comparison between the Sz and Control Relatives. {This analysis was performed in SAS Proc Mixed using a mixed effects regression of SPAN performance on avoidant symptoms and group (schizophrenia relatives vs. controls) with an interaction term and with random effect for family. Variance components structure was used for random effect (Littell, et al., 1996)}.
