Abstract
Background
Past research suggests that culture shapes the way psychopathology is experienced and expressed. Standard psychiatric assessment instruments may therefore not capture the same underlying constructs in different contexts. The present study investigated the factor structure of a standard depression scale in a sample of Rwandan genocide survivors.
Methods
One hundred ninety six Rwandan adults provided socio-demographic information and completed the Center for Epidemiological Studies-Depression scale (CES-D), one of the most widely used self-report instruments assessing depressive symptoms, as part of a larger study on well-being and mental health in Rwanda.
Results
A two-factor solution provided the best fit for these CES-D data. The first factor corresponded to general depressive symptoms (including depressed affect, somatic symptoms, and interpersonal concerns) and explained 37.20 % of the variance. The second factor included items assessing positive affect and explained 8.68 % of the variance.
Conclusions
The two-factor solution found in the present study deviates from the commonly reported four-factor structure, but is consistent with studies showing that depressed affect and somatic symptoms may not be experienced as distinct in certain non-Western and minority cultural groups.

Notes
We also reverse-coded this item to examine the resulting factor reliability, which was improved (Cronbach’s α = 0.71). However, this item still displayed a lower corrected item-total correlation (r = 0.19) than all four other items (all r s = 0.51−0.63). Furthermore, it remained unclear whether the content of this item was meaningfully related to the content of the four positive affect items. Given these limitations, we decided to exclude this item from the final solution.
