Parental Distress and Stress in Association with Health-Related Quality of Life in Youth with Spina Bifida: A Longitudinal Study.

The study used a generic quality-of-life measure that may not capture spina bifida-specific issues like bowel and bladder management, potentially explaining why few links were found with child-reported outcomes. Strong links between parent stress and parent-reported child quality of life may be exaggerated because the same person reported both, a bias known as common-method variance. The parenting stress measure used was validated only for parents of children aged 2–12, but was applied to parents of adolescents in this study. Many statistical tests were run, increasing the chance of finding false positives, though the authors adjusted for this in their main findings. Families who dropped out of the study may have been under greater stress, meaning the results might not reflect the most struggling families.

The study was supported by the National Institutes of Health and non-U.S. government sources. No specific commercial conflicts of interest were declared in the text.

Do not assume that reducing parental stress will directly improve the child's self-reported quality of life. The study found that parent stress was strongly linked to how parents rated their child's quality of life, but this link did not consistently hold for how the child rated it themselves.
