Abstract or Summary
  • The purpose of this study was three-fold: to determine how the false assumption of an abnormal heart condition affected the lives of false-positive students; the effects of phonocardioscan screening and cardiologist follow-up procedures on delabeled school children; and the effectiveness of the follow-up procedures used in delabeling the false-positive students. A questionnaire was mailed to the parents and teachers of 137 fourth-grade students living in the greater Portland area. These students were classified false-positive through the phonocardioscan screening program conducted as a demonstration project by the Oregon Heart Association during the school year 1969-70. Questionnaires were returned by 74.5 percent of the parents and 80.9 percent of the teachers. Statistical procedures utilized to analyze the data included parameter analyses to determine common properties descriptive of the population studied; Chi² analyses to determine applicable levels of confidence; and item analyses comparing teacher and parent-child responses within comparable areas. The major findings of this study are summarized in the following paragraphs. Of the total parent-child respondents, 9.18 percent were restricted in their activities; 66. 32 percent were not restricted but had been delabeled as a result of the screening program; and 24.5 percent had been delabeled prior to screening and had not been restricted. Following delabeling, 77.8 percent of the restricted group were removed from the restricted category, while 22.2 percent were still restricted. The high percent of delabeled students indicates the tremendous benefit derived from the screening program. Among the restricted group an improvement in academic achievement was noted following delabeling. Of great interest was the fact that 22.2 percent of the respondents indicated that their improvement in academic achievement had occurred following delabeling. Prior to delabeling 22.2 percent of the restricted group were below average in social acceptance, whereas following the delabeling process all were average or above in this category. The majority of respondents indicated that the students' school health records did not accurately reflect the current health status of their hearts. Furthermore, 88.9 percent of the delabeled respondents and 55.6 percent of the nondelabeled respondents indicated that the students' health records had not been changed following delabeling. These data reveal a critical need for maintaining more accurate and current school health records. Although a great diversity of personnel were involved in the follow-up procedure, well over 50 percent of the participating parent-child and teacher respondents indicated that they had not been informed of the screening results. This emphasizes the need for a systematic, organized, follow-up program.
