| Abstract: | The New York Longitudinal Study (NYLS) Parent Questionnaire assesses parental report of children's temperament on nine variables: Mood, distractibility, persistence, activity, rhythmicity, adaptability, approach-withdrawal, threshold and intensity. The present research was designed to assess the interrater reliability of this instrument and to provide cross-validation data regarding the nine scales. Questionnaires were validly completed by both parents of 47 children who had previously been evaluated at the Neuropsychology Laboratory of the Louisiana State University Medical Center. For each of the nine temperament variables, the scores obtained by each child when rated by his or her mother was significantly correlated with the score received on that variable when rated by the father. Thus, under the limitation imposed by the research design, it appears that parents are relatively consistent when evaluating the temperamental characteristics of their children. The correlations between each individual item and the factor it loads on were consistently highly significant. The nine temperamental variables are adequately assessed by the items included in the NYLS Questionnaire. |
