The current study involved the development, scaling, and validation of a new, brief, strength-based measure of children's ecological support, as rated by their parents. The scaling and validation of the Child and Youth Ecological Assets Scale--Parent Form (C-YEAS-P) took place through two studies. The first study involved 500 parents who were administered 32 pilot items for the C-YEAS-P. Once the data were collected, the measure was scaled with half of the sample (n = 250), resulting in a 12-item measure. A series of single-group confirmatory factor analyses (CFAs) were conducted using the second half of the sample to compare a three-factor model with two competing models, a one-factor model and a three-factor model with a higher-order factor. In addition, composite reliability estimates were calculated to examine the internal consistency of the scales. In the second study, 25 parents completed the new, 12-item C-YEAS-P and the Social Skills Improvement System Rating Scale (SSIS-RS) to evaluate evidence for convergent and discriminant validity of the C-YEAS-P scores. Pearson product moment correlations were computed between the three C-YEAS-P scale scores and the SSIS-RS Social Skills and Problem Behavior scale scores. The results of the first study supported a three-factor structure for the C-YEAS-P. In addition, the scores of each C-YEAS-P scale demonstrated excellent composite reliability. The SSIS-RS Social Skills scale scores provided good evidence for the convergent validity of the C-YEAS-P scale scores; however, the SSIS-RS Problem Behaviors scale scores provided mixed evidence for the discriminant validity of the C-YEAS-P scale scores.
