Over the past decade, cognitive approaches with children with developmental coordination disorder (DCD) have been investigated. Although studies have focused on intervention outcomes, few have documented the components of the approach that support the enhancement of children's performance. This study used systematic observation of videotaped intervention sessions to identify the frequency and type of strategies that four children with DCD used during a cognitive intervention (CO-OP). The strategies used by younger and older children were compared, with differences found in verbal-based strategy use. Cognitive strategy use appears to be more related to the individual child and intervention goal than to age. (Contains 4 tables and 7 figures.)
