Development and validation of a cervical cancer screening self-efficacy scale for low-income Mexican American women.
Although self-efficacy, a construct from social cognitive theory, has been shown to influence other screening behaviors, few measures currently exist for measuring Papanicolaou test self-efficacy. This article describes the development and psychometric testing of such a measure for Mexican American women. Data from two separate samples of Mexican American women ages>or=50 years, obtained as part of a study to develop and evaluate a breast and cervical cancer screening educational program, were used in the current study. Exploratory factor analysis indicated a single-factor solution and all item loadings were >0.73. Confirmatory analysis confirmed a single-factor structure with all standardized loadings>0.40 as hypothesized. The eight-item self-efficacy scale showed high internal consistency (Cronbach's alpha=0.95). As hypothesized, self-efficacy was correlated with knowledge, prior experience, and screening intention. Logistic regression supported the theoretical relationship that women with higher self-efficacy were more likely to have had a recent Papanicolaou test. Findings showed a significant increase in self-efficacy following the intervention, indicating that the measure has good sensitivity to change over time.
