Inconsistent practice exists among health care professionals for routine surveillance of obesity among school age populations. Until recently, research describing school nurse (SN) practice of Body Mass Index (BMI) screening in public elementary schools has been sparse, especially in terms of policy, environment, access to care, facilitating factors, and barriers. Healthy People 2010 Adapted Determinants of Health Model was used to guide the development of a 66 item tool to assess BMI screening in public elementary schools. Total survey design methods were used to develop the survey, to establish face and content validities, and to establish reliability using test retest. Four phases were used to psychometrically test the BMI Screening Survey. In Phase I, a small focus group (n=3) determined face validity. One FG participant indicated the survey included "all the nuts and bolts to screening kids in schools." In Phase 2, a panel of SN experts (n=3) evaluated the survey with a Content Validity Index (CVI) Evaluation Tool (ET). Using an item analysis bench mark of .67, and CVI benchmark of .80, eleven items were ranked as irrelevant and consequently eliminated. In Phase 3, a group of actively practicing SNs (n=10) used the CVI ET (0.833) and established validity of the 55 retained items. In Phase 4, the final version of the survey was assessed by a different group of actively practicing SNs (n=10). Each item was analyzed for stability reliability and 10 items were eliminated due to instability between test and retest. Results of this research advance the science of nursing so that SNs have a valid and reliable instrument to determine barriers to practice, to assist in policy development, and/or to facilitate change that allows for obesity prevention intervention in school settings.
