Oliver Sacks 'attended a conference on Tourette syndrome. Ninety-two specialists gave papers on [electrocardiogram] readings, electrical conductivity of the brain-all kinds of technical subjects. Sacks, the 93rd, got up and said, "It's strange. I've been sitting here all weekend and heard not one sentence on what it might be like to be an [individual with Tourette]".' As told to L. Weschler 1The conduct of qualitative health research (QHR) provides the tools to describe and deepen our understanding of children's (and their caregivers') perceptions and experiences of health, well-being, disability, and care. The value of conducting QHR studies, alone or as a component of a mixed methods project, is increasingly recognized in the fields of developmental medicine, 2 neurology, and rehabilitation sciences. 3 Diverse qualitative methodologies have been employed to study a variety of populations relevant to developmental medicine and child neurology, such as children and adolescents with epilepsy, 4 cerebral palsy, 5 acquired brain injury, 6 communication and cognitive disabilities, 7 and autism spectrum disorder. 8 However, inconsistent quality with respect to the conduct, reporting, and publishing of study methods is problematic, with many published articles consisting of studies where the researchers demonstrate a lack of methodological congruence between the study purpose, question, design, and methods, a lack of (or sometimes inaccurate) application of qualitative terms, and limited information about the purposeful sampling, data collection, or analysis techniques applied. The concept of methodological congruence 9 reflects a situation where the purpose, question, and research methods of a specific study are 'all interconnected and interrelated so that the study appears as a cohesive whole rather than as fragmented, isolated parts'. 10 To the experienced qualitative health researcher, commonly noted methodological flaws often include the omission of a study design,
