Arrangement of all quality of life items in two dimensions by nonmetric multidimensional scaling. a) responses of Immediate Work Group, b) responses of Delayed Work Group. Distances were determined as 1 minus the Spearman rank correlation coefficient for each pair of items: items with stronger correlations are closer to one another in space. The triangular points represent the Therapeutic Workplace phases. The color of each item indicates whether its correlational distance is closer to the Induction phase (dark red) or closer to the Opi+Coc phase (dark gray), and the shading is darker as a function of how closely the item is associated with the phase. The axis labels (x-axis as “Needs” and y-axis as “Activities”) represent our interpretation of the two dimensions made from inspection of the arrangement of the items.
