DAAP data were collected based on a set of 24 psychotherapy sessions from distinct treatments. The means and standard deviations for some of the variables are shown in the table below. Paired t-tests show that the difference in means is significant for Reflection (t = -2.763, p = .011); High WRAD Proportion (t = 3.727, p = .001); and Mean WRAD (t = 5.206, p = .000). The patient and therapist speech for these variables are also highly correlated. For Reflection, r = .671 (p = .000); for HWP, r = .472 (p = .020); and for Mean WRAD r = .679 (p = .000). For MHW, the difference in means is not significant, the correlation is .408 (p = .048). Negative Affect (r = .474, p = .019) and Sensory-Somatic (r = .473, p = .020) for patient and therapist speech are also correlated.
Covariations for the therapist are generally not computed, see the DAAP Technical Manual.
These data are in the process of being extended by adding additional session material and are also being compared to a large demographically balanced sample of spoken American English.
