Psychosocial consequences of false-positive newborn screens for cystic fibrosis.

This study was designed to develop a framework for understanding parents' perspectives about the psychosocial consequences of false-positive newborn screening (NBS) results for cystic fibrosis (CF). Through content analysis of interviews with 87 parents of 44 infants, we found that receipt of genetic information through NBS affected parents on intrapersonal and interpersonal levels within a relational family system. Repercussions included wondering about test accuracy, the child's health, and the future; gaining new perspectives and strengthening relationships; questioning paternity; wondering if other relatives had CF/were carriers; searching for the genetic source; sharing genetic information; supporting NBS; and feeling empathy for parents of affected children. We concluded that abnormal NBS results that involve genetic testing can have psychosocial consequences that affect entire families. These findings merit additional investigation of long-term psychosocial sequelae for false-positive results, interventions to reduce adverse iatrogenic outcomes, and the relevance of the relational family system framework to other genetic testing.

Long-term evaluation of genetic counseling following false-positive newborn screen for cystic fibrosis.

This cross-sectional mixed method study was a long-term follow-up evaluation of families who participated in an earlier survey of their understanding of cystic fibrosis (CF) genetics and their infants' false-positive CF newborn screening (NBS) results. Thirty-seven of the original 138 parents participated in the follow-up telephone survey. Results showed parents who received genetic counseling at the time of their infants' diagnostic sweat tests had significantly higher long-term retention of genetic knowledge than those without genetic counseling. However, both groups still had misconceptions and lacked accurate information about the actual risk associated with being a CF carrier. Most parents either had already informed (65%) or planned to inform (19%) their children about the child's carrier status. Mean child age at the time of disclosure was 9.2 years. Situational prompts were the most common reasons for informing their children. Neither parental knowledge, medical literacy, nor parental education predicted whether parents informed their children about their carrier status. False-positive NBS results for CF were not associated with parental perceptions of child vulnerability 11-14 years after the testing. Although the sample from this study was small, these findings underscore the benefits of genetic counseling at the time of the diagnostic sweat test and offer information that can assist parents in talking with their children about the implications of having one CFTR mutation.
