Prevalence and predictors of parental distress at the communication of positivity at newborn screening for metabolic diseases: an Italian longitudinal study.

Background: Receiving communication of positivity for metabolic diseases at Expanded Newborn Screening can be extremely stressful for parents, both in case of false positive and true positive cases. However, little is known about the predictors of distress and differential impact on mothers and fathers.

Methods: In this longitudinal study, 169 fathers and 171 mothers referred to one of the Italian metabolic centres for communication of positivity completed a survey including General Health Questionnaire-12, Emotion Thermometers (measuring stress, anxiety, depression, anger and need for help), Impact of Event Scale-Revised, Multidimensional Scale of Perceived Social Support and Emotion Regulation Questionnaire. Perceived severity and control of the children's health were also assessed. The survey was completed in person after the first session at metabolic centres and online after 1, 3 and 6 months.

Results: Nearly 80% of parents reported a clinical level of distress and anxiety after the communication of positivity, one-third of them reported post-traumatic symptoms and more than half of parents reported a need for help. After 6 months, there are still more than 30% of parents with a clinical level of distress and anxiety, 6% with post-traumatic symptoms and more than 20% who continue to express a need for help. No gender difference was reported and no differences emerged between pre-COVID-19 and post-COVID-19 periods for parental distress and post-traumatic symptoms.Social support, perceived severity and control of the child's health-but not gender or previous parental experience-predicted the post-traumatic symptoms at baseline while at 6 months the only significant predictor was perceived severity.

Conclusion: Adequate psychological support should be provided from the initial communication for both parents and for true positive, false positive and variants of uncertain significance/heterozygous carrier cases.
