health. Strengths and deficits in the current measurement strategies have been highlighted. Measures that assess health potential and provide more comprehensive assessment of functioning, as well as for composite measurements of health, need to be developed. Deficiencies in the assessment of health and influences on health during middle childhood and of special population subgroups also need to be addressed.
Movement toward frontiers in health assessment in children will be facilitated by the development of new tools from current and recent research efforts. A variety of instruments is available, many of which have been employed to good advantage in investigations of the outcomes of research interventions. The potential to adapt these tools for use in large population surveys should be explored.
