Developmental Relationships: An Interpretative and Validity Argument for Research and Practice in Child Well-Being
摘要
This paper crafts a validity argument for the core measures we have created and reported over the past decade to assess young people’s experience of developmentally significant relationships, or developmental relationships (DRs). In a sample of ≈ 11,000 middle and high school-aged youth in schools and out-of-school time programs in the United States, we conducted a series of rigorous analyses to build a systematic validity argument for a 5-item form measuring key elements of DR and a 20-item form measuring specific actions that operationalize those elements. Results showed that each DR measure performed as expected in Rasch analysis across items and people, with minimal differential item functioning, and supported previous findings that higher levels of DR predict positive outcomes. We conclude that the data have demonstrated a strong case for the theoretical and empirical validity of the DR measures as group-level research tools for informing PYD research, theory, and practice.
