Randomization
deficit of 6 CHWs over both conditions.
UCLA randomized matched clinic sites to the SC and the AC intervention conditions. There were 23 CHWs in the 4 SC clinics compared to 20 at the AC clinics; the number varied slightly due to resignations and hiring throughout the study. In particular, at one point in the study, a hiring freeze by the Provincial Dept. of Health resulted in a deficit of 6 CHWs over both conditions. At this point, the study agreed to pay the salaries of 6 new CHWs that the Dept. of Health hired, using their normal advertising, appointment, and training procedures. This was done in order to ensure that we were not evaluating the effect of a hiring freeze, but of CHWs’ implementation of home visiting in typical settings. These new CHWs received exactly the same 1-month training as the other CHWs who had been working from the start of the study.
