We’ll review Kohrt et al. (2011) with the goal of understanding why instrument validation is important and how careful work prior to validation can make an instrument culturally- and contextually-relevant.
Then we’ll turn to an example from my work in Kenya on perinatal depression. I’ll describe the formative study that we completed to come up with a set of 60 items that we used to assess perinatal depression among a sample of pregnant women and new mothers. You’ll use the results of this study to calculate the metrics we use to evaluate criterion validity—does the new scale we developed accurately measure this thing called depression?
