After enrollment, packet was mailed to participant and future phone call time frames set up to be able to call the participants back for an initial call to ensure packet received within one week of enrollment; with follow-up at 4 weeks after enrollment, 8 weeks after enrollment, and then a final phone call to ensure information would be mailed back at up to 4 weeks after the final phone call.

As the intervention was a survey and phone call, no serious adverse events were expected and none were reported by participants within one week; 4 weeks, or 8 weeks,or when contacted to ensure information would be mailed back at up to 4 weeks after the final phone call (within a maximum of 12 weeks of enrollment).
