Results of machine learning models predicting FIS scores from transcripts

FIS domain R2 Spearman’s rho p % human ICC
Verbal fluency .01 .27 < .001 .31
Hope and positive expectations .24 .53 < .001 .60
Persuasiveness .18 .47 < .001 .54
Emotional expression .00 .31 < .001 .34
Warmth, acceptance, and understanding .16 .46 < .001 .52
Empathy .18 .47 < .001 .55
Alliance bond capacity .15 .47 < .001 .52
Alliance rupture-repair responsiveness .13 .47 < .001 .54
Total score .19 .48 < .001 .52

Note: FIS = Facilitative Interpersonal Skills task (Anderson et al., 2009); R2 = cross-validated R2 that allows for negative values; p = p-value for Spearman’s rho; % human ICC = machine learning model performance relative to human coders’ intraclass correlation (ICC[3,8]).
