IRT is a paradigm for the development, analysis, and evaluation of measurement instruments (e.g., surveys or tests) for latent variables (i.e., constructs), such as attitudes, abilities, or achievement levels in the social sciences. IRT is sometimes referred to as latent trait theory, strong true score theory, or modern measurement theory, among ot...
Rating scale analysis is a procedure for evaluating rating scale func-tioning in item response data that includes participant responses in three or more ordered categories (e.g., Likert-type responses) for evi-dence of useful psychometric properties at the level of individual rating scale categories. To illustrate the concept of rating scale functi...
Rating scale analyses can be conducted on item responses across a range of survey research applications designed to measure unidimen-sional constructs using ordinal rating scales.1 There are no universal requirements for the maximum number of rating scale categories, minimum sample sizes for persons or items, or the proportion of missing data that ...

Put simply, rating scale analysis helps analysts learn about the quality of their rating scales from a psychometric perspective. Rating scale functioning is an empirical property of item response data that needs to be explored each time a survey is administered. Rather than assuming that rating scale categories are ordered as expected, describe uni...

To adequately cover the wealth of information while remaining within the scope of the Journal's 10-year updates, we have grouped the rating scales into several areas for sequential publication: overview, internalizing disorders, psychosocial scales, externalizing disorders, and miscellaneous scales. Within the four groupings, we have emphasized scales most relevant to practice in child and ...

The process of developing observational rating scales of behavior involves multiple steps. Because validation of a new scale is an iterative process involving different types of research, this process is best carried out in conjunction with a program of research where one anticipates.
