Construction and Psychometric Estimation of Health Screening Index

The Health Screening Index developed in the study contains 100 stress symptoms / ailments. The test is validated on a sample of 550 employees from industry as well as from banks both cooperative and nationalized. Psychometric assessment of Health Screening Index (HSI) is carried out by running a series of item analyses, factor analyses, reliability assessment, and validity assessment. For determining factorial validity of HSI, both component model and common factor model are employed. In each case, varimax (orthogonal) and promax (oblique) rotations are used. Results of varimax rotation are reported in the paper. Reliability assessment is carried out using Cronbach alpha and Armor theta. The test is validated against sick leaves. Two parallel forms of HSI are developed. Percentile norms are provided for interpretation of scores.
