Frontline Supervisor Survey Data Collection Report. Supervisors

A total of 1,126 supervisors were identified using the identification instrument: 421 at Time 1 and 705 at Time 2. From this population, 257 supervisors responded to the survey at Time 1, and 424 responded at Time 2 (Table 3).

The survey response rates were relatively high for a paper-and-pencil survey, especially since the Survey Research Center was unable to follow up directly with specific, individual supervisors. The overall response rate for Time 1 was 61 percent and for Time 2 it was 60 percent. At Time 2, Vermont had the highest response rate at 75 percent, while Oregon had the lowest at 52 percent.

NOTE: The Supervisor Survey data file contains 7 more observations than the Supervisor Identification Instrument data file (6 more at Time 1 and 1 more at Time 2); therefore, the detail of the number of surveys administered does not sum to the total, and the response rates by state at Time 2 may be slightly understated. The reason for this discrepancy was respondents removed identification numbers from their survey, which required the assignment of a new identification number when the survey was received and made it impossible to link that Supervisor Survey with the corresponding record in the Supervisor Identification file.

Table 4 shows response rates by provider type. At Time 1, home care agencies had the highest response rate (71 percent), while skilled nursing facilities had the lowest (53 percent), with assisted living facilities falling in between.

  Administered     Returned  
Time 1
   Skilled Nursing Facilities 189 101 53
   Assisted Living Facilities 148 92 62
   Home Care Agencies 90 64 71

   Assisted Living Facilities 178 93 52
   Home Care Agencies 149 114 77
   Adult Day Service Providers   20 13 65
   Total 705 424 60
NOTE: The detail of the number of surveys administered does not sum to the total and the response rates by provider type may be slightly understated. See note to Table 3 for further detail.

A slightly different pattern was observed at Time 2: home care agencies still had the highest response rate (77 percent), but assisted living facilities had a slightly lower response rate (52 percent) than skilled nursing facilities (57 percent).

Response rates at individual providers ranged from 0 percent to 100 percent at both time periods, with a median response rate across providers of 67 percent at Time 1 and 75 percent at Time 2 (data not shown). Response rates varied within provider type at both time periods. At Time 1, the greatest variation occurred within skilled nursing facilities, with an interquartile range of 22-100 followed by home care agencies (53-100), and assisted living facilities (44-85). This pattern changed at Time 2, with the greatest variation in response rates occurring in assisted living facilities (40-100), followed by adult day service providers (50-100), skilled nursing facilities (46-84), and home care agencies (75-100).

Item non-response in the Supervisor Survey was generally low, with most items having missing values in less than 5 percent of the cases. The total number of missing items in each survey also was low. Only 21 supervisors were missing 30 percent or more of their items.
