A sample (N = 1142) of applications for psychotherapy made at the health insurances was analyzed of characteristics as status of therapist, total number of sessions and weekly frequency of sessions. Analytic individual psychotherapy was the most often applicated (40%) of the four analyzed methods (depth-psychologically founded respectively analytical, individual respectively group psychotherapy). With regard to individual analytic psychotherapy low-frequent therapies (one or two sessions weekly) are as usual as higher-frequent ones (three or four sessions weekly). Only 20% of these higher-frequent therapies seemed to last more than 240 sessions totally.
