Abstract
The Family Outcomes Survey–Revised (FOS-R) measures family outcomes of services for young children with disabilities or developmental delays, and it can be used to investigate change in outcome achievement over time. To confirm the validity of FOS-R change scores, it must be established that the FOS-R measures the same construct over time; if so, score changes can be attributed to family outcome achievement. However, if not, interpretation of change scores may be misleading. Caregivers (N = 349) of Singaporean children with developmental delays receiving early intervention services completed the FOS-R Part A twice, approximately 1 year apart. Factor analysis was used to confirm the structure of the FOS-R Part A and to assess whether the scale measures the same thing across time (i.e., longitudinal measurement invariance). Results provided support for partial longitudinal measurement invariance, indicating that change scores on this scale can be validly interpreted with certain caveats.
期刊介绍:
Topics in Early Childhood Special Education (TECSE) communicates information about early intervention, which is defined broadly and includes services provided to (a) infants, toddlers, and preschoolers who are at risk for or display developmental delays and disabilities and (b) the families of such youngsters. TECSE includes articles on personnel preparation, policy issues, and operation of intervention programs. The intent is to publish information that will improve the lives of young children and their families. Manuscripts from (a) diverse theoretical perspectives, (b) all disciplines related to early intervention, and (c) all authors with information of value to the early intervention community are welcome. There are two topical issues—which address an identified problem, trend, or subject of concern and importance to early intervention—and two non-topical issues.
