Barriers and Facilitators to Services Knowledge Item 20: Results from HRSA/HAB's SPNS Innovative Models of Care

Knowledge Item: CA-Barriers and Facilitators to Services-20
Test-Retest Reliability for Barriers to Services

In a sample of 352 clients from seven Cooperative Agreement Projects, the test-retest correlation for barriers to services for the entire sample is .345 (p < .001). For 92 men, r = .357 (p < .001) and for 260 women, r = .340 (p < .001). The mean number of days between assessments for the total sample is 271.0 (SD = 231.4). The mean number of days between the earliest and most recent assessments for men is 180.2 (SD = 153.4); the mean number of days for women is 303.1 (SD = 245.7).

When controlling for the number of days between the earliest and most recent assessments, the test-retest partial correlation for the total sample is .349 (p < .001). The test-retest partial correlation for men is .352 (p < .001) and the test-retest partial correlation for women is .342 (p < .001).

[The smoother line used in this plot has a filter value of 3.0 meaning that the line is fairly "rigid" and follows trends in the data in a somewhat abstract way. The cloud is jittered 3%.]
