A Brief Assessment of Concerns Associated With Genetic Testing for Cancer: The Multidimensional Impact of Cancer Risk Assessment (MICRA) Questionnaire

Health Psychol. 2002 Nov;21(6):564-72.

Abstract

The Multidimensional Impact of Cancer Risk Assessment (MICRA) is a new tool to measure the specific impact of result disclosure after genetic testing. The authors compared its performance with that of questionnaires measuring general and cancer-specific distress. Participants (158 women) responded 1 month after they received genetic test results. The women were divided into 4 standard clinical test result groups: BRCA1/2 positive, BRCA1/2 negative, panel negative, and true negative. Factor analysis supported the formation of 3 subscales: Distress (6 items, alpha = .86), Uncertainty (9 items, alpha = .77), and Positive Experiences (4 items, alpha = .75). All 3 MICRA subscales differentiated participants who were BRCA1/2 positive from the other 3 groups. MICRA thus helps identify subgroups of vulnerable genetic testing participants.
