Treatment Adherence and Fidelity
The mean (SD) number of sessions attended was 2.3 (1.5) and 5.7 (3.9) for SPS at steps 1 and 2, respectively, and 6.2 (3.7) at step 2 and 6.0 (4.2) at step 3 for CBCM. A total of 199 recordings (65 participants; 24 clinicians) were rated for fidelity, a mean (SD) of 3.1 (2.1) per participant and 8.3 (9.3) per clinician. The probability that each type of treatment was given as intended was estimated to be 0.95 (95% CI, 0.88-0.98) for SPS and 0.59 (95% CI, 0.51-0.67) for CBCM, indicating higher fidelity to SPS (
