Taylor Complex Figure test: administration and correction according to a normalization and standardization process in Spanish population
INTRODUCTION. The Taylor Complex Figure (TCF) was created as an alternate form for the Rey-Osterrieth Complex Figure. Although both figures are widely used, to date, it has not been carried out the normalization of the TCF for Spanish population.
AIM. To normalize and standardize the TCF taking into account the sociodemographic characteristics of the Spanish population.
SUBJECTS AND METHODS. The present study is part of the Normacog Project. Seven hundred participants were recruited (18-90 years old), assessing the visuo-constructive ability and immediate visual memory by TCF. The effect of age, level of education and gender was analyzed on the performance of TCF and percentiles and scalar score for eight ranges of age and scalar score adjusted by the level of education.
RESULTS. Results showed a significant effect of age and level of education on the performance in copy and memory of TCF, whereas gender was not significant. Age and education explained from 25.3% to 35.7% of the variance of TCF performance. The older and less educated, the worse performance shown in TCF. Percentiles, scalar score for each range of age and scalar score adjusted by the level of education were obtained. CONCLUSION. Administration instructions, scoring and the normative data of the TCF are provided taking into account the Spanish sociodemographic characteristics for adults in our country.
