Mullen Scales of Early Learning (MSEL) Composite Score Primary · Month 6, month 12

The Mullen Scales of Early Learning (MSEL) assesses child developmental domains: visual reception, gross motor skills, fine motor skills, receptive language, and expressive language. A composite t-score derived from standardized t-scores of the four domains (excluding gross motor) provides a measure of g, the general measure of fluid intelligence thought to underlie general cognitive ability. The composite t-score ranges from 40 to 130. The t-scores have mean 100 and standard deviation 15 in the Western population. Higher scores reflect better outcome. Measure is applicable to children only, n

Child Urine Thiocyanite Level Primary · Month 6, month 12

Technicians collected samples of urine on the same day as child assessments, so that they are contiguous with level of cyanide exposure from current poorly processed cassava. Urine thiocyanite levels in urine were measured in micromol per liter. The range was 0-1032, higher scores reflect worse outcome. Data collected from children only, not collected from caregivers.

Home Observation for the Measurement of the Environment (HOME) Score Secondary · Month 6, month 12

Home Observation for the Measurement of the Environment (HOME) composite measure designed to assess the quality and quantity of stimulation that the child is exposed to in their home environment. The Infant/Toddler version includes 45 items answered on the scale from 0=none to 3=good. A total HOME score was generated by summing item responses. Potential range is 0 to 135. Higher HOME scores indicate higher quality of home environment. Measure applies to children only.

Child Physical Growth: Length for Age Z-score Secondary · Month 6, month 12

Length for age z-score was determined using the World Health Organization algorithm using child's length, sex, and age at the time of measurement. The world population mean is 0 with standard deviation 1. Z-scores of -2 or below are often used to indicate stunting.

Caregiver Anxiety Symptoms Secondary · Month 6, month 12

The modified Hopkins Symptom Checklist was used to assess caregiver anxiety. The instrument included 9 yes/no items, and the item responses were summed into the total score. The potential range was 0-9 with higher score indicating worse anxiety. Measure applicable to caregiver only. Data were not collected from children.

Sponsor's own description

The proposed research adapted the caregiver training and child neurodevelopmental assessment capacity that the PI previously built in Uganda beginning in 2008, to a community-based intervention model for the prevention of konzo in the Democratic Republic of Congo.
