Conversely, studies might impact a therapy traditionally used in one domain for use in the other to test the effect of physical rehabilitation on changing the course of depression in a sample of depressed persons, or to test the effect of depression therapies in improving the function of persons with disabilities. One example of this kind of strategy is a study conducted by Singh and colleagues (1998), who randomized a community sample of elderly adults meeting DSM-IV criteria for major depression (N = 20).

These studies are most vulnerable to three types of problems: (1) selection bias, (2) confounding, and (3) measurement error. The importance of selection bias was discussed earlier in the context of data sources, with the main point being that both depression and disability affect help seeking in different kinds of care settings, so that the relationships between the two observed in one setting may differ from those in other settings. Selection bias may not affect the internal validity of longitudinal analyses of the relationship of depression and disability over time, although the external validity in terms of generalizability to other types of individuals would need to be demonstrated.
