RESUMO
BACKGROUND: Timely detection of neurodevelopmental impairments in children can prompt referral for critical services that may prevent permanent disability. However, screening of impairments is a significant challenge in low-resource countries. We adapted and validated the rapid neurodevelopmental assessment (RNDA) instrument developed in Bangladesh to assess impairment in nine domains: primitive reflexes, gross and fine motor development, vision, hearing, speech, cognition, behaviour and seizures. METHODS: We conducted a cross-sectional study of 77 infants (0-12 months) in rural Guatemala in July 2012 and July 2013. We assessed inter-rater reliability and predictive validity between the 27-item RNDA and the 325-item Bayley Scales of Infant and Toddler Development, Third Edition (BSID-III) and concurrent validity based on chronic malnutrition, a condition associated with neurodevelopmental impairments. For both RNDA and BSID-III, standardized scores below 80 were defined as borderline impairment. RESULTS: Children came from rural households (92%), were born to indigenous women of Mayan descent (73%) and had moderate or severe growth stunting (43%). Inter-rater reliability for eight RNDA domains was of moderate to high reliability (weighted κ coefficients, 0.49-0.99). Children screened positive for impairment in fine motor (17%) and gross motor (14%) domains using the RNDA. The RNDA had good concurrent ability; infants who were growth stunted had higher mean levels of impairment in gross motor, speech and cognition domains (all p < 0.001). The RNDA took 20-30 min to complete compared with 45-60 min for BSID-III. CONCLUSIONS: Wide-scale implementation of a simple, valid and reliable screening tool like the RNDA by community health workers would facilitate early screening and referral of infants at-risk for neurodevelopmental impairment.

OBJECTIVE: To compare the efficacy of an outreach program for young children with cerebral palsy with center-based and "minimal intervention" control groups. DESIGN: Randomized controlled trial conducted in a group of 85 children between the ages of 1.5 and 5 years. Urban children were allocated to a daily center-based mother-child group or to monthly training of their parents along with a pictorial guidance manual. Rural children were allocated either to parent training or health advice. Outcome measures were changes in children's adaptive skills, maternal stress and adaptation to the child, satisfaction with social support, and knowledge of handling a physically disabled child. RESULTS: Fifty-eight children were successfully followed up. The pattern of change in children's adaptive skills was as predicted (ie, least progress in the health advice group). Positive effects of intervention also included increased maternal knowledge and perceived helpfulness of support from formal sources. However, maternal adaptation increased most in the health advice group with minimal intervention. When children had attended a program at least 4 times, their skills improved, and mothers' adaptation did increase. CONCLUSIONS: Outreach training for mothers in Bangladesh can help them to improve the skills of their young children with cerebral palsy and is perceived as helpful.
