In test construction, thorough effort is put into formulating test items. Commonly, however, these are scaled with category or Likert scales. In this study, items from four work-related questionnaires were adapted and scaled with the Borg CR Scale^® (CR100, centiMax^®), a general intensity scale for level determination with ratio data (Borg & Borg, 2001; Borg, 2007). Tests measured Work-related Basic Need Satisfaction, Organizational Citizenship Behavior, Perceived Organizational Support, and Procedural Justice. In their original forms, Cronbach’s alpha ranged from 0.74–0.98, whereas this study obtained 0.83–0.92 (n=30 and n=81). Adapted to the centiMax scale, Cronbach’s alpha were 0.72–0.95 (n=81 and n=142). For Work-related Basic Need Satisfaction (n=81) and for Organizational Citizenship Behavior (n=30) correlations between centiMax and Likert scales were r=0.79 (p<0,001) and r=0.69 (p<0,001). The centiMax scale worked well and can be recommended with the advantage of more interesting statistical analysis that comes with ratio data.
