Expansion and validation of the spiritual health locus of control scale: factorial analysis and predictive validity.

The present study reports on the development and validation of an expanded scale assessing spiritual health locus of control beliefs. Additional items were developed, and the scale was pilot tested among 108 church-attending African American women. The scale was multidimensional, comprised of the original Active and Passive Spiritual dimensions, and additional subscales reflecting 'Spiritual Life and Faith' and 'God's Grace'. Internal consistency was acceptable, and predictive validity was evidenced by negative correlations between the Passive Spiritual dimension and knowledge about mammography, breast cancer, and breast cancer treatment, and mammography utilization. This instrument provides an in-depth assessment of beliefs regarding the role of God in one's health, and may be useful for the development of church-based health education serving African Americans.
