Distrust, predisposition to use health services and breast cancer screening: results from a multicultural...

To examine whether and how distrust of the health system and predisposition to use healthcare services influence frequency of mammograms and Clinical Breast Exams (CBEs).

A community-based survey recruited 184 women (age 47+/-12); 49% were college-educated, 77% had health insurance, and 57% were non-white. Distrust was measured with a four-item scale (Cronbach alpha=0.71); predisposition to use health services with an 11-item scale (Cronbach alpha=0.84). Ordinal regression analysis was used to test two models examining "time since last mammogram" and "time since last CBE." The later model had a better goodness-of-fit, as indicated by a non-significant, Pearson coefficient.

Distrust to the health system was significantly correlated with age (r=-0.19*), income (r=-0.16*), and predisposition to use health services (r=-0.26**). Distrust predicted time since last CBE (B: 0.37, SE: 0.19*), which in turn was significantly correlated with time since last mammogram (r=0.44**). Predisposition to use health services predicted time since last CBE (B: -0.78, SE: 0.19**) and time since last mammogram (B: -0.47, SE: 0.22**). Insurance predicted time since last CBE (B: -0.94, SE: 0.44*), while age (B: -0.21, SE: 0.03**) and income (B: -0.19, SE: 0.09*) predicted time since last mammogram.

Distrust of the healthcare system and predisposition to use health services influence breast cancer screening directly. Distrust interferes with behavioral patterns that favor recurrent breast cancer screening.

Trustworthiness in the healthcare system and positive attitudes for the use of, health services enhance routine breast cancer screening. *p<0.05, **p<0.001.
