Self-help is also part of humanistic psychology: Sheila Ernst and Lucy Goodison have described using some of the main humanistic approaches in self-help groups.[37]
Co-counselling, which is an approach based purely on self-help, is regarded as coming from humanistic psychology as well.[38]
Humanistic theory has had a strong influence on other forms of popular therapy, including Harvey Jackins' Re-evaluation Counselling and the work of Carl Rogers, including his student Eugene Gendlin; (see Focusing) as well as on the development of the Humanistic Psychodrama by Hans-Werner Gessmann since the 80s.[39
