  7. Relabeling Internal Validity Campbell, 1986 Internal

  8. Relabeling Internal Validity Campbell, 1986 Internal Local modal causal validity

  9. Local Modal Causal Validity Local • Only applies to current study -- zero generalizability • Can apply to hodgepodge compositeprograms • Still concerned with ruling out alternative explanations Modal Causal

  10. Relabeling External Validity Campbell, 1986 External

  11. Relabeling External Validity Campbell, 1986 External The principle of proximal similarity

  12. Principle of Proximal Similarity • A reaction to the sampling theoryof generalizability • Based on the natural sciencemodel of high internal validity • Places current study within a generalizability space • Views generalization as a question of degree

  13. Proximal Similarity Our Study

  14. Proximal Similarity Settings Our Study Times People Places
