Document Summary
Identify and define the construct to be measured. Not everyone has the same definitions of a construct, need to be explicit and specific. Consider different manifestations (e. g. , cognitive, physiological, behavioural) and content areas (e. g. , at home, with others, with partner, at work): generate an item pool. Base this on the outcome of stage 1. Should contain anywhere between 1. 5 to 10 times the items than what you want on the actual test insures that you have the best possible items. Anything that has to do with the patient"s past but is meant to reflect their current state e. g. , i shoplifted as a child. Cannot change the past, and many people will not shoplift as adults, so this does not reflect the current behaviours of the patient. Localisms do not use items that are only relevant in certain areas of the world (e. g. , i love snowball fights ): determine the format for measurement.
