Reliability and validity of general health questionnaire (GHQ-12) for male tannery workers: a study carried out in Kanpur, India

Objective: To analyse the internal structure of the 28-item version of the General Health Questionnaire (GHQ-28), as well as its reliability and validity in relation to other variables in a sample of Ecuadorian university students. Method: Instrumental design with confirmatory factor analysis using weighted least square mean and variance adjusted (WLSMV) estimator, reliability and convergence and discrimination validity of the GHQ-28. Sample: 495 students (56.6% women), between 18 to 35 years old (M = 24.1 years; SD = 2.1), from three universities (59.6% public) in Ecuador. Results: The bifactor model of the GHQ-28 test has an adequate fit with χ2 = 357.81; p > .05; df = 322; χ2/df = 1.11; CFI = .991; TLI = .989; SRMR = .059; RMSEA = .015 [.000 – .023]; ωH = .93; ECV = .90; PUC = .78. The GHQ-28 is reliable and in terms of convergent validity, it correlates significantly and negatively with mental health, assessed by MHC-SF, and it is discriminant between risk and non-risk cases. Conclusion: The GHQ-28 bifactor model is replicable in Ecuadorian college students.

Simultaneous Identification

Literature pertinent to the use of the various versions of the General Health Questionnaire (GHQ) is briefly surveyed. The literature indicates that the 60-item version has the highest reliability and validity coefficients, the lowest misclassification rate, and the highest sensitivity and specificity. Using data from a previously published community survey in Perth using the 60-item GHQ, comparisons are made between use of the 60-, 30-, 20- and 12-item versions, including community prevalence rates, simultaneous identification of cases, disagreement rates and patterns of community rates with age. The 60-item version gives the lowest prevalence rates. It is argued that the 60-item GHQ is probably the best as it gives the lowest misclassification rates, the smallest standard error of estimated prevalence rates and allows measurement of certain subscales not contained within the shorter versions.

Misclassification Rates

General Health Questionnaire (GHQ) results are given for a large (N = 1013) sample of South Australian young people (average age 19.6 years), to compare the usefulness of the 12-, 28-, and 30-item forms of the GHQ. Internal reliabilities are generally adequate and the Likert scoring method produces significant correlations with psychological measures such as self-esteem. the case-prevalence rate using the binary scoring method was comparable with other studies, but misclassification rates were unacceptably high when DSM-Ill Axis I diagnosis was used as the criterion for the presence of any psychiatric disorder.
