Pbkp_redicting change for individual psychotherapy clients on the basis of their nearest neighbors

Abstract:

This study extended client-focused research by using the nearest neighbor (NN) approach, a client-specific sampling and pbkp_rediction strategy derived from research on alpine avalanches. Psychotherapy clients (N = 203) seen in routine practice settings in the United Kingdom completed a battery of intake measures and then completed symptom intensity ratings before each session. Forecasts of each client's rate of change and session-by-session variability were computed on the basis of that client's NNs (n = 10-50 in different comparisons). Alternative forecasts used linear or log-linear slopes and were compared with an alternative pbkp_rediction strategy. Results showed that the NN approach was superior to the alternative model in pbkp_redicting rate of change, though the advantage was less clear for pbkp_redicting variability.
