RESULTS	The PAEI score for both groups combined increased from 6.9 to 8.6 ( on a scale of 0-15 ) from baseline to immediately postintervention ( P = .01 ) and was 8.2 ( P = .09 ) at 6-month follow-up ; most of the improvement in PAEI score was due to increased use of 5As skills by Group 2 clinicians .\
