  5. Design and Sample Design: Cross-sectional Sample: 23 rural hospitals from the eastern U.S. 591 Registered Nurses Data source: Written survey (SCC) at baseline 5

  6. Nurse Demographics

  7. Hospital Demographics

  8. SCC Description • 24 items with response format: • 1= not at all • 2= less than ½ of the time, • 3= more than ½ of the time and • 4= all of the time • 2 items with response format: • 10 point (1-not at all to 10- very)

  9. FL*= Factor Loadings

  10. FL*= Factor Loadings

  11. Convergent Validity • Total SCC was positively associated with comfort in smoking cessation counseling (r=.604, p<.000) and comfort in referral to resources (r=.630, p<.000). • When controlling for age, gender, work status, education and ethnicity, comfort with smoking cessation counseling independently predicted higher total SCC scores, explaining 36% of variance in SCC (adjusted R2 =0.36).

  12. Psychometrics • Reliability: • Cronbach’s alpha = 0.955 • Validity: • Exploratory Factor Analysis: All items loaded on four factors (explained 68.3% of SCC variation) • Convergent validity: Controlling for nurse characteristics, comfort in smoking cessation counseling predict higher SCC scores (R2 = 0.36)
