Technical Information

Normative non-clinical data for the CTIP was collected over a six year period and across a number of sites (community, university, city, and rural). The sample was drawn from major regions of the United States and Canada and was representative of the populations in regards to gender, age, ethnicity, urban/rural residence, and geographic distribution. Percentile scores are derived from a large, cognitively-intact normative sample of 386 people. The sample ranges in age from 15–74 years and is stratified into four age groups; 15–24 years, 25–44 years, 45–64 years, and 65–74 years of age. Back to the top
