Pearson correlation coefficients sensitive to change were -0. 49 (p -value = 0. 11) and 0. 679 (p-value = 0. 025) when compared to 1) DSM-IV TR and 2) HRSD, respectively. ICC oflnter-rater and Intra-rater reliability were both 0.99 when compared to either 1) DSM-IV TR or 2) HRSD. Cronbach 's alpha of Internal consistency was 0. 96 and 0. 92 when compared to 1) DSM-IV TR and 2) HRSD, respectively.
