2. Examine the effects of the interventions delivered to adult dependents of AD or retired military personnel on the weight of AD or retired military personnel themselves. The working hypothesis, based on preliminary data, is that there will be a "ripple" effect of program benefits from intervention participants to the AD or retired military personnel they live with; specifically, overweight and obese AD or retired military personnel will lose more weight if their partner is randomized to the HWL intervention compared to the CBP intervention, because the weight loss of AD or retired military personnel indirectly exposed to the intervention will be proportional to the weight loss of their adult dependent who is directly exposed.
