Abstract [en]
A non-clinical sample (n=71) answered an online survey containing the Patient Health Questionnaire-9 (PHQ-9), that rates the frequency of symptoms of depression (DSM-IV). The questions were also adapted for the Borg CR Scale® (CR100, centiMax®) (0–100), a general intensity scale with verbal anchors from a minimal to a maximal intensity placed in agreement with a numerical scale to give ratio data). The cut-off score of PHQ-9?10 was found to correspond to ?29 cM. Cronbach's alpha for both scales was high (0.87) and the correlation between the scales was r=0.78 (rs=0.69). Despite restriction of range, the cM-scale works well for scaling depression with added possibilities for valuable data analysis.
