Study Summary

The purpose of this study is to determine whether a home-based intervention matched to stage of change (readiness) for using effective methods to prevent or reduce depression can improve depression outcomes in primary care.

Primary Outcome

Depression was assessed using the Beck Depression Inventory, 2nd Edition (BDI-II)(Beck, Steer, \& Brown, 1996). In this self-report measure, 21 symptoms of depression are rated on a 0-3 scale.

The change scores reported here are the difference between the total BDI-II scores at baseline and 9 months (i.e., 9 months minus baseline). Change scores range from -63 to +63, with larger negative scores indicating greater re
