The Psychometric Adequacy of Adults with Borderline Intellectual Functioning Screening Checklist

This study developed, validated, and standardized screening checklists to select and intervene early in the selection and intervention of adults with borderline intellectual functioning. In the development of the adults with borderline intelligence functioning selection checklist, cognitive, language and communication, occupation, sociality, and emotional areas and constituent factors were derived through analysis of previous studies and test tools, and each focus group interview was conducted with borderline adult parties, parents, and experts. After developing preliminary questions through this, the content validity was verified through Delphi for incumbent teachers and related workers and the final 30 questions were selected. 91 borderline intellectual functioning groups and 300 standard groups were selected and analyzed. The construct validity of the selection checklist examined through the reliability and confirmatory factor analysis examined through Cronbach's α was good, and there was a significant difference between the standard group and the borderline intellectual functioning group in the discriminant validity, and finally, a significant positive correlation was observed in the reference validity through the slow learner selection checklist. Based on these results, the validity of the adults with borderline intellectual functioning selection checklist was verified, and implications for the development of the selection checklist and future research directions were discussed.
