Cognitive orientation to daily occupational performance (CO-OP): part I--theoretical foundations.

This paper is the first in a series of three papers that present the systematic development and evaluation of Cognitive Orientation to daily Occupational Performance (CO-OP). CO-OP is a cognitively based, child-centred intervention that enables children to achieve their functional goals. In Part I, the breadth of literature that provides the theoretical underpinnings for the approach is reviewed. Parts II and III provide a description of the approach and present the evidence to support its use with children with developmental coordination disorder.
