Setting research priorities to improve the health of children and young people with neurodisability: a British Academy of Childhood Disability-James Lind Alliance Research Priority Setting Partnership. The National Institute for Health Research (NIHR) commissioned this study as part of an information-gathering exercise in response to this. Design, setting and participants: More than 70 professionals (therapists, service leads, paediatricians and education staff) and 25 parents participated in a qualitative interview (either individually or as part of a focus group). Results: Professional thinking and models of service delivery are in a state of flux and development. There is a move towards goals-focused, family-centred approaches. Work tends to be highly individualised, with few protocols. Parents are certain of the value of therapies, although they may experience difficulties with provision and may seek (additional) private provision. Therapy interventions are conceived as three components: the therapist, the procedures/equipment, etc. They are believed to be highly complex and poorly understood. Although participation is widely endorsed as a core intervention objective of therapy interventions, its suitability, or appropriateness, as an outcome measure was questioned. Other child and/or parent outcomes were identified as more or equally important. Notions of intermediate outcomes – in terms of body structure/function, and the achievement of activities – were regarded as important and not counter to participation-focused approaches. Among therapists, research on intervention effectiveness was (cautiously) welcomed. A number of methodological challenges were identified.

The use of the more conservative abilities: phonologic awareness, phonologic memory, and methods of case definition are clearly more costly for select- rapid naming (18,19). Phonologic awareness refers to the ing subjects, but they may prove more valid and useful in understanding that words can be broken down into pho- finding biological markers of LD. Phonemes are the smallest sound unit that changes the meaning of a word (e.
