Development and Preliminary Validation of Learning Disability Scale: A Parent, Teacher Report Screening Measure
Nishtha Kumar | Dr. Amool Ranjan Singh
Abstract: The present study was conducted to develop a valid and reliable screening measure e.g scale for assessment of Learning Disabilities. The study is a pilot study for the original tool, which is divided in two phases. In Phase I a culturally relevant item pool was generated through a review of literature and conducting interviews with primary school teachers, parents of primary school children, school counselors and school psychologists, and existing scales of learning disabilities. In phase II, psychometric properties e.g Reliability and Validity of the scale were established on a sample of 30 students and seven constructs of the scale were explored. These seven factors were reading, writing, arithmetic, spatial ability, social functioning which consisted of social cognitions, memory etc, Attention/concentration, and anxiety. The scale demonstrated good internal consistency, as indicated by a respectable Cronbach's alpha coefficient of (? = 0.986) for the total scale. The test-retest reliability analysis for the parent version of the scale yielded an exceptionally high interclass coefficient of 0.999. Similarly, the teacher version of the scale showed good reliability with an interclass coefficient of 0.962, suggesting consistent ratings from teachers over time. The inter-rater reliability analysis revealed a substantial level of agreement between parent and teacher ratings of the child on the Learning Disability Scale, as indicated by a kappa value of 0.860. The study holds useful implications for teachers, parents, school counselors and clinicians.
