Psychometric properties of Colorado Learning Difficulties Questionnaire (CLDQ)

The Colorado Learning Difficulties Questionnaire (CLDQ) is a new parent-report rating scale that was developed to provide a brief screening measure for learning difficulties. This study examined the psychometric properties of CLDQ. The statistical population included all elementary school pupils of Ardabil city. Data were gathered from 374 parents of students who were enrolled in school in 2011-2012. The sample was selected using multistage cluster sampling procedure. The CLDQ was found to have good internal consistency (Cronbach''s alpha was 0. 90) and test-retest reliability (0. 94). The content، discriminant and construct validity of the questionnaire were found to be desirable. Just as in the original measure، exploratory and confirmatory factor analysis revealed five correlated but distinct factors labeled reading، social cognition، social anxiety، spatial difficulties and math. Findings confirm the CLDQ as a valid and reliable instrument for the assessment and screening of students with learning difficulties.
