Increasing mammography among women aged 40-74 by use of a stage-matched, tailored intervention.

Background: Tailoring is a promising technique for encouraging greater performance of health-related behaviors. Tailored interventions are designed to be more individualized to personal characteristics, in contrast to "standard" interventions where all participants receive the same materials.

Methods: A total of N = 1864 women aged 40-74 were recruited from a staff model HMO and randomly assigned to one of three intervention groups: (a) No Educational Materials, (b) Standard Materials, and (c) Stage-Matched Materials.

Stages of adopting regular screening mammography: do women differ in decisional balance within stages?

This study examined whether distinct subgroups of women could be identified within stages of adoption for screening mammography. These subgroups may represent differential readiness to move to the next stage of the adoption continuum. Data were from a baseline survey of 1323 women between the ages of 50 and 74 years who were recruited through a staff- model HMO for an intervention study to increase rates of mammography.

Integrating pros and cons for mammography and Pap testing: extending the construct of decisional balance to two behaviors.

Background: The ability to study health-related behaviors in combination rather than singly will lead to a more comprehensive approach to health promotion. This investigation focused on mammography and Pap testing. One index was created to reflect the recency of receiving both examinations.

Why do women's attitudes toward mammography change over time? Implications for physician-patient communication.

The present study examines women's decision making about mammography over a 1-year period, using "decisional balance," a summary of women's positive and negative perceptions about mammography derived from the Transtheoretical Model (TTM). Data were from a survey of women ages 50-74 years who completed both the baseline and 1-year follow-up telephone surveys (n = 1144) for an intervention study to increase the use of mammography screening. A shift toward less favorable perceptions about mammography was related to being a smoker and not having a recent clinical breast examination and Pap test.

Screening mammography and constructs from the transtheoretical model: Associations using two definitions of the stages-of-adoption.

The two purposes of this investigation were: (a) to examine whether an association existed between stages of adopting regular mammography and decision-making constructs from the Transtheoretical Model (TTM) of behavior change, and (b) to determine whether any such associations would be found for each of the two ways of defining the stages-of-adoption. One method integrated past screening history with a report of future intention for screening; the other method used a single item with predetermined response categories. Data were from the baseline survey of 1,323 women aged 50-74 who were recruited as part of an intervention study through a local Health Maintenance Organization.
