PURPOSE: The effects of testing and screening on quality of life may influence the future behavior of society, but have not been quantified. We derived a health classification and survey items for the morbidities of testing and screening, to be the foundation of a multiattribute utility instrument, the Temporary Utilities Index. METHODS: Seventy-six women ranked the importance of attributes of the testing process after breast biopsy. Seven survey items on the testing process were subsequently developed and assessed for clarity by a second group of 19 patients. The items cover attributes of mental and physical well-being before, during, and after testing. A survey panel of 164 subjects accessed online used the items to endorse expected and experienced effects of colon screening and mammography. They also endorsed items from a colorectal benefits and barriers scale, a risk perception scale, and EQ-5D, to utilize in the analyses of validity of the TUI items. RESULTS: Based on criteria from the literature and limited psychometric analysis, the items showed evidence of practicality, validity, and a strong association with barriers. CONCLUSIONS: The TUI health classification and survey items show evidence of validity, and may inform economic analysis, once combined with utility weights.
