Abstract
Instrument design should consider the measurement of constructs that are directly linked to how well the data is generated and subsequently measured and assessed. We need sufficient instruments and archival data that will solve problems for the improvement of human life, inclusive of health-related issues. The purpose of this chapter is to examine the methodological approaches the psychometrician reviewed in order to determine if a need existed to create an adequate, effective, and robust instrument, or if the current primary and/or archival data would be adequate for the study related to healthy aging. The intent of the researchers is to examine the relationship between instrumentation and data and to develop a checklist for instrumentation and data collection. A comprehensive literature review and a final evaluation instrument is constructed that may assist the researcher in the validity and reliability of instrumentation a priori and post-hoc instrument construction in the future.
