Development and preliminary standardization of the "extended complex figure test" (ECFT).
Recognition and matching trials were designed for the Rey-Osterrieth Complex Figure Test (ROCFT). Following pilot testing and expert review, they were standardized using 90 community-dwelling adults (58% female, ages 30 to 88). Recognition has 30 multiple-choice items for different figural elements; scores distributed normally with strong item-total correlations and with normally distributed item difficulties. Cronbach alphas were .84,.61, and .81 for the Total, Global, and Detail Scales. Recognition correlated .81 with ROCFT recall and .65 with Visual Reproductions. Matching has 10 multiple-choice items; scores were negatively skewed with a substantial ceiling effect. Alpha for Matching was .58, limited in part by few items. Matching correlated .68 with Judgment of Line Orientation and .74 to .90 with copy trials. Both Recognition and Matching discriminated 34 patients with intractable epilepsy from 34 matched controls. Overall, Recognition appeared to be reliable and showed evidence of validity. By comparison, Matching reliability and validity were less impressive and warrant further examination.
