Evaluation of Family Preservation and Reunification Programs: Final Report - Volume One. 2.5 Lengths of Time from Random Assignment to the Interviews

12/01/2002

Table 2-7 shows lengths of time between random assignment and each interview--initial, post-treatment, and followup--as well as the lengths of time between the initial and post-treatment interviews.

Kentucky. For the 311 initial interviews with caretakers, the length of time from random assignment to completion ranged from 1 to 50 days with an average of 12.6 days (s.d. = 8.1 days, 75% within 16 days, 90% within 23 days). For the 280 caseworker initial interviews, the length of time from random assignment to interview completion ranged from 3 days to 75 days with an average time of 17.6 days (s.d. = 9.36 days, 75% within 23 days, 90% within 28 days).

At post-treatment, 294 caretakers were interviewed, and the length of time from random assignment to interview completion ranged from 24 days to 111 days with an average of 44.8 days (s.d. = 10.5 days, 75% within 49 days, 90% within 58 days). Three hundred twenty-six caseworker interviews were completed in an average of 51 days (s.d. = 14.3 days) after random assignment, with a completion time ranging from 10 days to 142 days (75% within 55 days, 90% within 68 days). For 3 of the cases where services were terminated early (10, 14, and 17 days after random assignment), post-treatment interviews were completed at the time of termination, thus the minimum of 10 days.

With a goal of completing initial interviews within two weeks of the referral date, the intent was to capture each family's situation at the inception of family preservation or regular services. However, initial interviews with caretakers took an average of over 12 days to complete and initial interviews with caseworkers took an average of over 2 weeks to complete. No significant differences were found between control and treatment groups with regard to the time from random assignment to completion of any of the interviews.

As already noted, the first interview was to be conducted within two weeks of the referral and the second interview was to be conducted at the end of service provision or a comparable time. Therefore, it is expected that for those cases where both interviews were completed, approximately four weeks should have passed between the dates of the first and second interviews. Two hundred and eighty-seven caretakers completed both the first and second interviews, and the average length of time between these interviews was 32.3 days (s.d. = 10.3 days, 75% within 37 days between interviews, 90% within 45 days between interviews). For the 274 caseworkers who completed both interviews, the average length of time

between these interviews was 33.2 days (s.d. = 13.3 days, 75% within 38 days between interviews, 90% within 49 days between interviews). (17)

Followup interviews were completed by 219 caretakers an average of 379.9 days after random assignment (s.d. = 14.9, 75% within 387 days, 90% within 401 days). The difference between experimental and control groups with respect to the length of time between random assignment and followup interviews was not significant.

New Jersey. On average, the 325 initial interviews with caretakers were completed 15.3 days (s.d. = 8.5 days) following random assignment (for three cases we do not have the date of the interview). The range in time to completion was 1 to 50 days (75% were completed in 20 days, 90% in 27 days). As in Kentucky, it is not possible to consider the first interview as representing the situation at the inception of family preservation or regular services. In the case of the family preservation cases, these interviews were conducted, on average, two weeks into a four-week intervention. For the 388 caseworker initial interviews, the mean time to completion was 15.6 days (s.d. = 8.1) with a minimum of 2 and a maximum of 40 (75% within 21 days, 90% within 28 days).

For the 344 caretaker post-treatment interviews, the average length of time between random assignment and interview was 52.1 days (about 7 and a half weeks, s.d. = 11.8 days) with a minimum of 33 and a maximum of 116 days (75% within 58 days, 90% within 68 days). For 434 caseworker post-treatment interviews the average was 56.0 days (s.d. = 14.7) with a minimum of 13 and a maximum of 115 (75% within 63 days, 90% within 75 days, interviews on cases that terminated early were sometimes conducted before the end of the 28 day service period, hence the minimum of 13). There were no significant differences between the experimental and control groups in the average lengths of time to interview except for the caseworker post-treatment interview. For the control group, this interview was conducted an average of 58.7 days after random assignment while the average for the experimental group was 54.4 days (p = .003). (18)

Both caretaker interviews were completed in 292 cases, with an average of 37.3 days between interviews (s.d. = 11.2, 75% with not more than 43 days between interviews, 90% not more than 49 days). Three hundred eighty-four caseworkers completed both interviews with an average of 39.8 days between interviews (s.d. = 15.0). (19)

Followup interviews were completed by 218 caretakers an average of 383.5 days after random assignment (s.d. = 25.1, 75% within 389 days, 90% within 399 days). The difference between experimental and control groups with respect to the length of time between random assignment and the followup interviews was not significant.

Tennessee. On average, the 117 initial interviews with caretakers were completed in 15.4 days (s.d. = 7.0 days) after random assignment. The length of time to completion for these interviews ranged from 2 days to 36 days (75% were completed in 20 days, 90% in 26 days). Similar to both the Kentucky and New Jersey caretaker interviews, these interviews were conducted, on average, two weeks into a four-week intervention. Therefore, the first interview should not be considered representative of the family's situation at the inception of family preservation or regular services. The 112 initial caseworker interviews were completed in an average of 14.5 days (s.d. 7.2 days) after random assignment, with a range of 3 to 34 days (75% completed within 18 days, 90% completed within 23 days). The length of time from random assignment to completion of the initial interview with caseworkers was significantly shorter for the control group than for the experimental group (11.8 days vs. 16.5 days, p = .0004).

The length of time between random assignment and the post-treatment interview was significantly different for experimental and control groups on both the caretaker and the caseworker interviews. Therefore, these timeframes are reported separately for each group. The 80 post-treatment interviews with caretakers in the experimental group were completed in an average of 47.9 days (s.d. = 10.3 days) after random assignment, while the 37 post-treatment interviews with control group caretakers were completed in an average of 51.9 days (s.d. = 10.6 days) after random assignment (p = .05). This time period ranged from 32 days to 80 days for the experimental group (75% in 54 days, 90% in 64 days) and from 29 days to 70 days for the control group (75% in 61 days, 90% in 67 days). For the caseworker interviews, the 90 post-treatment interviews in the experimental group were completed an average of 59.7 days (s.d. = 18.5 days) after random assignment, whereas the 48 post-treatment interviews in the control group were completed an average of 47.8 days (s.d. = 9.7 days) after random assignment (p = .0001). The length of time from random assignment to the initial caseworker interview ranged from 37 to 135 days (75% within 68 days, 90% within 83 days) for the experimental group, and from 36 days to 91 days (75% within 48 days and 90% within 61 days) for the control group.

One hundred and eight caretakers completed both the initial and post-treatment interviews, with an average of 33.6 days between the interviews (s.d. = 10.1 days, 75% with not more than 41 days between interviews, 90% with not more than 47 days). For the 112 caseworkers completing both the initial and post-treatment interviews, there was a significant difference between the experimental and control groups in length of time between interviews (p = .03). Forty-six caseworkers in the control group completed both interviews with an average of 35.7 days between the interviews (s.d. = 12.3, 75% with no more than 38 days between, 90% with no more than 55 days). Sixty-six caseworkers in the experimental group completed both interviews with an average of 42.3 days between the interviews (s.d. = 17.5, 75% with not more than 49 days between, 90% with not more than 60 days between).

Followup interviews were completed by 95 caretakers an average of 385.5 days after random assignment (s.d. = 25.9, 75% within 394 days, 90% within 404 days). The difference between experimental and control groups with respect to the length of time between random assignment and the followup interviews was not significant.

Philadelphia. A total of 263 initial interviews with caretakers were completed, and the length of time from random assignment to completion of these interviews ranged from 9 to 85 days with an average of 28.54 days (s.d. = 11.28 days, 75% within 36 days, 90% within 44 days). For the 163 caseworker initial interviews, the length of time from random assignment to interview completion ranged from 12 days to 86 days with an average time of 37.12 days (s.d. = 16.11 days, 75% within 45 days, 90% within 59 days). For both the caretaker and the caseworker initial interviews, the length of time between random assignment and interview completion was significantly longer for the control group. For caretaker initial interviews, the treatment group averaged 26.54 days (s.d. = 26.54 days) and the control group averaged 31.46 days (s.d. = 31.46 days, p = .0009). For the caseworker initial interviews, the average number of days between random assignment and interview completion in the treatment group was 34.07 days (s.d. = 14.49 days), and the average number of days in the control group was 44.0 days (s.d. = 17.57 days, p = .0002).

At the end of the treatment period, 261 caretakers were interviewed, and the length of time from random assignment to interview completion ranged from 68 days to 180 days with an average of 111.55 days (s.d. = 13.58 days, 75% within 118 days, 90% within 129 days). For the caseworkers, 250 post-treatment interviews were completed in an average of 129.48 days (s.d. = 28.43 days) after random assignment, with a completion time ranging from 100 days to 270 days (75% within 140 days, 90% within 164 days). There were no significant differences between experimental and control groups in the length of time from random assignment to post-treatment interview completion for either the caretaker or the caseworker interviews.

Two hundred and twenty-five followup interviews were completed with caretakers. The length of time from random assignment to the followup interview ranged from 223 days to 438 days with an average of 360.59 days (s.d. = 37.95, 75% within 379 days, 90% within 391 days). Experimental and control groups did not differ significantly in the amount of time between random assignment and followup caretaker interviews.

As noted, the first interview was to be conducted within two weeks of the referral and the second interview was to be conducted at the end of service provision or a comparable time. Therefore, it is expected that for those cases where both interviews were completed, approximately 12 weeks (or 90 days) should have passed between the dates that the first and second interviews were conducted. Two hundred and nineteen caretakers completed both the first and second interviews, and the average length of time between these interviews was 81.21 days (s.d. = 14.94 days, 75% with 75 days between interviews, 90% with 90 days between interviews). For the 160 caseworkers who completed both interviews, the average length of time between these interviews was 89.57 days (s.d. = 27.68 days, 75% with 103 days between interviews, 90% with 123 days between interviews). The average number of days between initial and post-treatment caretaker interviews was significantly greater for the experimental group than the control group (124 days vs. 95 days, p = .007). The same was true for the time between caseworker initial and post-treatment interviews, with an average of 112 days for the experimental group and 48 days for the control group (p = .0001).
