  1. Note, there were no significant differences between the group with one year compared with the group with two years of treatment regardless of which follow-up scores were compared
  2. aISR items are scored from 0 to 4; subscale scores are calculated by forming the average of respective responses; hence, mean scores in a given subscale range from 0 (no self-reported symptoms) to 4 (maximum amount of self-reported symptoms)
  3. *Significant differences at p < .05 level (robust ANOVA, Brown-Forsythe) between respective Baseline, 1-year, and 2-year follow-up scores
