Reliability of the Wraparound Observation Form--Second Version: an instrument designed to assess the fidelity of the wraparound approach.

The push to rapidly implement the wraparound approach for families of children with serious emotional disturbance (SED) has resulted in a number of service models that may or may not be in accordance with its theoretical foundation. Given the number of wraparound programs being implemented nationwide, the need to develop instruments that can measure the fidelity of wraparound services in a reliable manner should not be ignored. The purpose of this study was to examine the interobserver agreement of the Wraparound Observation Form--Second Version (WOF-2), an observation system designed to assess the fidelity of wraparound services. Observations were conducted across 30 family planning meetings where wraparound services were provided. The mean percentage agreement across the 48 items was 96.7% (range 83.3-100%) and the average kappa statistic was 0.886 (range = 0.318-1.0). On the basis of these results, the WOF-2 appears to be a reliable instrument for assessing the delivery of wraparound services.
