文摘

Item Response Theory (IRT) techniques were applied to examine the psychometric properties of a 39-item adapted version of Champion’s Health Belief Model scales. The 39-item instrument can be reduced to 24-items without loss of relevant information. Results can be used to gather formative data on diverse populations and to develop interventions to improve cervical cancer screening. The 24-item instrument demonstrated good internal consistency among women living with HIV. Future work should focus on validating the properties of the reduced instrument in diverse samples.
