Two measurement models of testing measurement equivalence: an example of Child Behavior Checklist

In children's mental health, many psychological assessments are critical to measure end outcomes. And equally valid measures are essential for health services outcome research in diverse populations. Examination of equal validity in tests measuring the emotional, motivational, attitudinal, and interpersonal characteristics of children can be achieved with factor analytic tools. Factor analysis assumes a particular measurement model, effect indicator model. However, some psychological measures such as Child Behavior Checklist are not clear whether effect indicator model is assumed. In this paper, an alternative measurement model, causal indicator model, was introduced. Measurement equivalence of CBCL was tested using multiple group analysis based on effect indicator model and using principal component analysis based on causal indicator model. The results showed that measurement equivalence tests based on the two measurement models in CBCL led to similar conclusions. We conclude that the two measurement models could be complementary for explaining differential validity of psychological measures across sub-populations.

Anticoagulant-related nephropathy (ARN) was initially described in patients on warfarin (as warfarin-related nephropathy) and recently in those using dabigatran. Herein, we report clinical history and kidney biopsy findings in a patient on apixaban (Eliquis). Initiation of treatment with apixaban resulted in aggravation of preexisting mild acute kidney injury (AKI). A few days after apixaban therapy, the patient became oligoanuric, and kidney biopsy showed severe acute tubular necrosis with numerous occlusive red blood cell casts. Only one out of 68 glomeruli with open capillary loops had small segmental cellular crescent. Therefore, there was major discrepancy between the degree of glomerular injury and the glomerular hematuria. Considering that the onset of this AKI was associated with apixaban treatment initiation, we propose that this patient had ARN associated with factor Xa inhibitor (apixaban), which has not previously been described. Monitoring of kidney function is recommended after initiation of anticoagulant therapy.
