Technical Information

IEQ–MP has a normative data base of 957 individuals within a general medical group, as well as, a subset of other medical conditions including arthritis, cancer, cardiac conditions, chronic pain, headache, and kidney disorders. The User’s Manual documents the specific details of the normative data.

Reliability and Validity
IEQ–MP was developed following rigorous procedures. The User’s Manual presents detailed data about key development standards, emphasizing the following points: 

  • Test-retest reliability
  • Internal reliability and internal consistency
  • Factor analysis
  • Correlational studies
  • Sensitivity to treatment changes

The construct validity of IEQ–Self-Report was investigated by examining correlations with measures of depression and illness behavior; the multivariate analysis of the association between IEQ–S and depression in medical patients with other depression-related factors has also been taken into account. In addition, four case studies are included to provide concrete examples of potential uses of IEQ–MP in a variety of settings.
