摘要
This study psychometrically evaluates the Motivational Interviewing Treatment Integrity Code (MITI) to assess fidelity to motivational interviewing to reduce sexual risk behaviors in people living with HIV/AIDS. 74 sessions from a pilot randomized controlled trial of motivational interviewing to reduce sexual risk behaviors in people living with HIV were coded with the MITI. Participants reported sexual behavior at baseline, 3-month, and 6-months. Regarding reliability, excellent inter-rater reliability was achieved for measures of behavior frequency across the 12 sessions coded by both coders; global scales demonstrated poor intraclass correlations, but adequate percent agreement. Regarding validity, principle components analyses indicated that a two-factor model accounted for an adequate amount of variance in the data. These factors were associated with decreases in sexual risk behaviors after treatment. The MITI is a reliable and valid measurement of treatment fidelity for motivational interviewing targeting sexual risk behaviors in people living with HIV/AIDS.
