This study was conducted to assess the psychometric properties of the Barkin Index of Maternal Functioning (BIMF) in an Ethiopian context. Data were obtained from 202 women with a child less than 1 year of age. Narrow standard deviations characterized responses to most BIMF items, but a handful of items had wider standard deviations associated with bimodality. Most interitem correlations were < |.15|, and 13 of the 20 BIMF items did not load satisfactorily on any factor in exploratory factor analyses. Two factors emerged from the remaining items, one with three items and the other with four. Although poor reliability results relating to internal (interitem) and temporal consistency could be attributed to limited variability in the data, a number of concerns are raised about the BIMF itself, including its content validity, instructions, response options, and usefulness in healthcare settings. Suggestions are made for improving the assessment of maternal functioning in Ethiopia and other contexts. More generally, this research demonstrates that researchers should not assume that the psychometric properties and appropriateness of scales will remain robust when those scales are used in contexts that differ from the contexts in which they were created.
