The four steps involved in instrument development are: concept identification; item construction; validity testing and reliability testing. The clinician who has begun to identify characteristics associated with a patient group has in reality begun the process of instrument development.

Exploratory factor analysis helps us to determine the factor structure of the instrument. This provides insight into which factors best explain the variation among the items on the instrument. These empirically derived constructs are then compared with the judgmentally developed categories reviewed previously. If the empirically derived constructs ...
An item analysis can be conducted along with or even prior to the factor analysis. It is always helpful to examine item frequencies, percentages, means, and standard deviations. Items associated with either high or low means and low standard deviations should be reviewed and considered for deletion. Also, examine the pattern of correlations of item...
The final analysis of the pilot data consists of examining the internal consistency reliability of the data from the item clusters defining each subscale (Chapter 7). In addition, create subscale scores by taking the means of each subscale, and compute the means and standard deviations of each of the subscales as well as the correlations among all ...

MEASURE Approach to instrument development, an acronym of seven empirically supported steps for instrument development, and initial score validation that he developed based on the recommendations of leading psychometric researchers and based on his own extensive background in instrument development.
Step 1: Definition and elaboration of the construct intended to be measured. The first step in instrument development is conceptualization, which involves defining the construct and the variables to be measured.

Instrument design is performed through three- steps process, including determining content domain, sampling from content (item generation) and instrument construction. 11,14 the first step is determining the content domain of a construct that the instrument is made to measure it.
