The meaning of construct validity and techniques for its estimation are discussed. Of particular interest is the appropriate role of factor analysis (and related techniques) in construct validation efforts. A comprehensive view of construct validity is encouraged, as well as a cautious interpretation of the construct validity evidence available for many existing instruments.
More than 500 elementary school personnel from a large Colorado school district provided perceptions of the unmet mental health needs of their students, the likely causes of the needs, and suggestions about solutions or programs to meet the needs. The district's definition of "mental health"--positive self-image, healthy interrelationships with peers and adults, and acquisition of school skills and competencies--guided the questionnaire design. Respondents perceived numerous unmet mental health needs, most involving about 15% of the student population. The most frequently perceived problems were poor decision-making and problem-solving skills, poor self-image, low self-confidence, inability to resolve interpersonal conflicts, depression/unhappiness, low motivation, and various conduct disorders. Further, most respondents believed children's unmet mental health needs are increasing, and the causes for most problems are family-and home-related, but most suggested solutions were school-based. Recommendations include increasing the involvement of school nurses in programs aimed at improving children's mental health.

Interest in and use of qualitative methodological strategies in evaluating research have increased considerably in the last few years. Many of the recent evaluation frameworks or models are entirely or partly oriented toward use of qualitative methods. A number of methodological issues and concerns have been raised, including the appropriateness of validity and reliability estimation for the measurement strategies employed in qualitative evaluations becoming more common in health and other fields. In this article, the views of prominent qualitative methodologists on this topic are briefly summarized; a case is made for the relevance of validity and reliability estimation; definitions of validity and reliability for qualitative measurement are presented; and appropriate estimation techniques are suggested. It is hoped that discussions such as this will promote increased attention to validity and reliability concerns in qualitative evaluations and thus help improve the quality of those evaluations.
