Parental Views on the Psychosocial Impact of False-Positive Results Following Newborn Screening for Severe Combined Immunodeficiency in England.

The project aimed to explore the psychosocial impact on parents of receiving a false-positive outcome following a positive newborn bloodspot screening (NBS) result for SCID for their child. A mixed-methods design was employed using semi-structured interviews and standardised health-related questionnaires (EQ-5D-5L, ITQOL-47, and GAD-7). The participants were recruited from six National Health Service hospital trusts in England involved in the NHS England In-Service Evaluation of Screening for SCID. A total of 22 interviews were conducted with 28 parents. Health-related questionnaire data were collected from 26 of these parents. The interviews were analysed using a reflexive deductive approach to thematic analysis. For the health-related questionnaire data, a comparison of group means against population norms was undertaken using t-tests with unequal variances. The findings from the interviews showed that receiving a false-positive outcome following a positive NBS SCID result could cause parents to have an enhanced view of their child's vulnerability in the short term. However, negative sequelae were largely mitigated as parents viewed their child's exposure to 'normal' infections as evidence of a functional immune system. The health-related questionnaire data showed that the parents had significantly worse health than the population norm (as indicated by EQ-VAS: p = 0.0296); however, all the other measures were non-significant. More research is needed to explore the potential longer-term psychosocial impact of a false-positive screening result for SCID on parents beyond their child's first year of life.
