| Number of items in scalea | Scale Cronbach’s α | Overall (N = 105) mean (SD) | Low HL (N = 36) mean (SD) | High HL (N = 64) mean (SD) | P values | |

aThe two single item questions addressing participant satisfaction with the personal action plan were not combined due to an unacceptable Cronbach’s α.

cn = 99; differential responses due to missing data.
dn = 98; differential responses due to missing data.
en = 99; differential responses due to missing data.
