Motivation forweb-basedtreatment: to what extent is the patient motivated to work on the eMental health intervention in his or her treatment	Motivation is an important issue in forensic mental health care according to the interviews Lack of trust in effectiveness was not an important topic in the interviews; therefore, remove it for conciseness Rephrase item because the instrument has to be filled out by a therapist (after discussing with the patient)
15. Working alliance: Is there a good working alliance or do you (therapist and client) expect that a good working alliance will be developed? Note: Here it is important that you (the client) recognize your own contribution to the therapy and are aware of what is expected of you.
