Several Months After He Randomly Assigned Nursing Home Residents to Either

Several months after he randomly assigned nursing home residents to either have control or a lack of control over visitation schedules,Richard Schulz (Schulz & Hanusa,1978) was dismayed to find that those residents who had originally controlled the duration and frequency of visits from college students later experienced poorer health and higher mortality rates.These findings seem directly at odds with research by Judith Rodin and Ellen Langer (1977) ,until one considers that

A) Langer and Rodin studied women and Schulz studied men.
B) people sometimes blame themselves for health problems.
C) a lack of perceived control is worse than losing it.
D) Schulz induced only a temporary sense of control, which was lost when the visits stopped.
E) Schulz did not control for the severity of the health problems.
