      • See especially Content Validation Guidelines starting page 244.
  • Validity Evidence Based Upon Internal Structure and Relation to Other Variables
    • Review Table 1, p. 35-36 in the Brown (2010) Construct Validity article linked above.
      • Study the two subjects in Table 1 entitled:
        •  4. Internal Structure Evidence
        • 5. Relations to Other Variables Evidence
      • Note the examples of validation activities in Table 1 for these two subject.
      • Recall that you read the following to articles for an activity:
        • Ragheb, M. G., & Beard, J. G. (1982). Measuring leisure attitude. Journal of Leisure Research, 14, 155-167.
        • Menon, S.T. (2001). Employee empowerment: An integrative psychological approach. Applied Psychology: An International Review, 50, 153-180.
      • Review both the Ragheb & Beard and Menon articles and identify specific evidence that they provide to address "4. Internal Structure Evidence" and "5. Relations to Other Variables Evidence" for validity as discussed in Brown (2010).
