FIGURE 2. Cluster analysis of psychosis-risk questionnaire reports.

FIGURE 2

k-Means cluster analysis was used on results from the mPRIME item severity scores, with gender included in the analysis. In total, 908 participants were included in the analysis, which required completion of all items, without answering “don’t know” on any item. Severity scores on each item were renumbered such that 0=definitely disagree, 1=somewhat disagree, 2=slightly disagree, 3=slightly agree, 4=somewhat agree, and 5=definitely agree.
