Customized Employment Fidelity Scale Research

The CEI is conducting research customized employment fidelity scales. The purpose of this research is to (a) establish the construct validity of the discovery fidelity scale (DFS) and job development fidelity scale (JDFS) by determining if the factor structure is theoretically established and (b) examine the convergent and predictive validity of the scales pertaining to employment outcomes.

  • RQ1: Is the factor structure theoretically established on the discovery fidelity scale?
  • RQ2: Is the factor structure theoretically established on the job development fidelity scale?
  • RQ3: Does fidelity during the discovery (DFS) impact fidelity in the job development phase.
  • RQ4: Does fidelity during development and impact employment outcomes such as job obtained and wages.
