Cross-cultural measurement invariance of the General Health Questionnaire-12 in a German and a Colombian population sample.

While the General Health Questionnaire, 12-item version (GHQ-12) has been widely used in cross-cultural comparisons, rigorous tests of the measurement equivalence of different language versions are still lacking. Thus, our study aims at investigating configural, metric and scalar invariance across the German and the Spanish version of the GHQ-12 in two population samples. The GHQ-12 was applied in two large-scale population-based samples in Germany (N = 1,977) and Colombia (N = 1,500). To investigate measurement equivalence, confirmatory factor analyses were conducted in both samples. In the German sample mean GHQ-12 total scores were higher than in the Colombian sample. A one-factor model including response bias on the negatively worded items showed superior fit in the German and the Colombian sample; thus both versions of the GHQ-12 showed configural invariance. Factor loadings and intercepts were not equal across both samples; thus GHQ-12 showed no metric and scalar invariance. As both versions of the GHQ-12 did not show measurement equivalence, it is not recommendable to compare both measures and to conclude that mental distress is higher in the German sample, although we do not know if the differences are attributable to measurement problems or represent a real difference in mental distress. The study underlines the importance of measurement equivalence in cross-cultural comparisons.

Different treatment thresholds in non-Western children with behavioral problems.

OBJECTIVE: First, to investigate whether non-Western children in the Netherlands are less likely to be treated for behavioral problems than Western children; second, to examine whether discrepancies in treatment status are related to differences in level of problem behavior and impairment. METHOD: The study included 2,185 children of the four largest ethnic groups in the Netherlands, namely, 684 Dutch, 702 Moroccan, 434 Turkish, and 365 Surinamese children from grades three to five of elementary school. Teachers completed the Strengths and Difficulties Questionnaire and five DSM-IV items on externalizing problems. In addition, they provided information on the treatment status of the child. RESULTS: Moroccan boys displayed more problem behavior, Turkish boys less problem behavior, and Surinamese boys similar rates of problem behavior compared with Dutch boys. No difference in problem behavior was found between Western and non-Western girls. Adjusted for age, level of problem behavior, and impairment, Moroccan and Turkish children and Surinamese girls were less likely to receive treatment for problem behavior. CONCLUSIONS: The higher treatment thresholds of non-Western children compared with Western children in the Netherlands could not be explained by differences in level of problem behavior or impairment. Detection of behavioral problems in non-Western children should receive more attention.
