Social support was assessed using a 9-item scale adapted from the 20-item Medical Outcomes Study Social Support Survey (MOSS Survey) [25]. The positive social interaction subscale and several other items were eliminated for brevity. In addition, the response scale was changed to range from 0 to 4 instead of 1 to 5. Participants were asked how often someone was available to help them if they were confined to a bed, to talk to about their problems, to give them advice, and to show them love and affection. Response choices were: 0 = “None of the time”, 1 = “A Little of the Time”, 2 = “Some of the Time”, 3 = “Most of the Time”, and 4 = “All of the Time”. Responses were summed to form a total score with a possible range of 0 to 36. Reliability of the social support scale was 0.82 for females and 0.80 for males.
