Cognitive Screening (TRIACOG) for adults with cerebrovascular diseases : construction process and validit

Abstract

This study presents the construction process of the Cognitive Screening Instrument (TRIACOG) for evaluating poststroke adults. The TRIACOG has undergone a rigorous developmental process: (a) literature review; (b) analysis of the most sensitive items on a brief neuropsychological evaluation to differentiate between clinical and healthy cases; (c) addition of items; (d) content analysis by expert judges; (e) reformulation of the instrument; (f) pilot study; (g) reformulation of the instrument; (h) a second pilot study in a clinical sample; and (i) analysis of evidence of criterion validity. The TRIACOG evaluates 8 functions: orientation, verbal and visual episodic-semantic memory, praxis, attention/working memory, executive functions, language, and numerical processing. The TRIACOG provides evidence of content and criterion validity. This article may guide the construction of items of other neuropsychological instruments. It is hoped that the TRIACOG may contribute to studies and neuropsychological clinical trials that evaluate poststroke patients.
