A Cronbach's <jats:italic>\u03b1<\/jats:italic> coefficient of 0.85 and a mean inter\u2010item correlation of 0.21 indicate high internal consistency. The tool demonstrates good agreement between testers and near excellent temporal stability with intraclass correlation coefficients respectively of 0.85 and 0.90. s\u2010PCFT\u2010I total scores do not differ by sex or age, while statistically significant differences are observed between people with different levels of severity of ID. Moderate to good and highly significant correlations (\u22120.40 to \u22120.66) among the s\u2010PCFT\u2010I total scores and subscores and the Sum of Cognitive Score of the informant\u2010based Dementia Questionnaire for Persons with Intellectual Disabilities suggest an acceptable level of concurrent criterion validity.
