  1. Data Reduction for County-Level Demographics and Contextual Variables

  2. Methodology • Began with 48 Kentucky demographic and context variables from wide variety of sources (see maps) • Exploratory factor analysis • Principal component, varimax rotation • Eigenvalue set at 1.0 for inclusion • Used standard of .5 factor loading or above for inclusion within a factor • High degree of separation occurred with clear explanatory value

  3. Results • Ten principal factors emerged, accounting for 70.8% of total variance • They were labeled as: • FACTOR 1: Low SES • FACTOR 2: Family functioning • FACTOR 3: School bonding • FACTOR 4: Pregnancy outcomes • FACTOR 5: Disengaged youth • FACTOR 6: Teen pregnancy • FACTOR 7: Pre-natal health care • FACTOR 8: Safety and crime • FACTOR 9: HS graduate achievement • FACTOR 10: Elementary school reading • Especially useful in demonstrating variability across state in terms of concentrations of different types of problems • Undoubtedly, these are “proxy” variables

  4. Demographic & Contextual Variables Likely to be Correlated with ATOD Use and Abuse Factor 1: Low SES (Income, child poverty, SSI, Medicaid, Food Stamps, AFDC, WIC, KTAP, unemployed) (Factor loadings by county)

  5. Demographic & Contextual Variables Likely to be Correlated withATOD Use and Abuse Factor 2: Problematic Family Functioning (Abuse, Neglect, GP as Caregivers, Injuries) (Factor loadings by county)

  6. Demographic & Contextual Variables Likely to be Correlated withATOD Use and Abuse Factor 3: Poor School Bonding (Drop-out, ADA, Retention) (Factor loadings by county)

  7. Demographic & Contextual Variables Associated with ATOD Use and Abuse Factor 4: Positive Pregnancy Outcomes (Gestation, birth weight) (Factor loadings by county)

  8. Demographic & Contextual Variables Likely to be Correlated withATOD Use and Abuse Factor 5: Disengaged Youth (not in school, not working) (Factor loadings by county)

  9. Demographic & Contextual Variables Likely to be Correlated withATOD Use and Abuse Factor 6: Teen Pregnancy (Teen births, teen repeat births) (Factor loadings by county)

  10. Demographic & Contextual Variables Likely to be Correlated withATOD Use and Abuse Factor 7: Prenatal Health Care (Service accessed, # visits) (Factor loadings by county)

  11. Demographic & Contextual Variables Likely to be Correlated withATOD Use and Abuse Factor 8: Problematic Safety & Crime (Crime rate, violent death) (Factor loadings by county)

  12. Demographic & Contextual Variables Likely to be Correlated withATOD Use and Abuse Factor 9: HS Achievement Levels (ACT composite) (Factor loadings by county)

  13. Demographic & Contextual Variables Likely to be Correlated withATOD Use and Abuse Factor 10: Elementary-level Reading (6th Gr. CTBS) (Factor loadings by county)
