A recent special issue of the Journal of Pediatric Psychology included papers focused on evidence-based assessment across several broad domains of assessment in pediatric psychology (eg, adherence, pediatric pain, and quality of life). In one of these papers, Holmbeck et al.(2008) reviewed strengths and limitations of existing measures of psychosocial adjustment and psychopathology, concluding that many measures lacked supporting psychometric data (eg, basic indices of reliability and validity) that would permit a complete evaluation of these measures. Given that measure development and validation papers are frequently published in JPP (Brown, 2007), it is important that we attend to guiding psychometric principles when developing and disseminating data on new measures to be employed with pediatric populations (Nunnally & Bernstein, 1994). Thus, the purpose of this paper is to present and describe a checklist for authors to use when submitting measure development papers to JPP. This checklist is included in the Appendix and is also included at the following link on the JPP website: http://www. oxfordjournals. org/our_journals/jpepsy/for_authors/measure% 20development% 20checklist. pdf

Findings presented by Holmbeck et al.(2008) indicated that 34 of the 37 measures reviewed met preestablished ‘‘evidence-based assessment’’(EBA) criteria for ‘‘well-established’’measures (Cohen et al., 2008). To be considered ‘‘well-established,’’a measure had to have been presented in at least two peer-reviewed journal articles by different investigatory teams, have demonstrated adequate levels of reliability and validity, and be accompanied by supporting information (eg, a measure manual). Although most measures that we reviewed met these criteria, we also found that most of the 34 ‘‘wellestablished’’measures were hampered by at least one major psychometric flaw and/or lacked important
