NOTE. Patient factors were rated as present or not present. Observations lack statistical independence because of multiple observations on each patient and made by each therapist.

Abbreviation: LOE, level of effort.

^*Number of observations were OT (45,770 sessions), PT (50,383 sessions), and ST (42,402 sessions).

^†All between-group comparisons were statistically significant at P<.0001.

^‡Effect size calculated as Cohen d using pooled sample SD.
