Explanation for the choice of comparators {6b}
In order to control for the novelty of a tablet computer within the consultation, and to control for the repeated measurement of quality of life, an active comparator (DIALOG scale) will be used within the trial. The DIALOG scale comprises 11 items made up of eight life domains (mental health, physical health, job situation, accommodation, leisure activities, friendships, relationship with family/partner, personal safety) and three treatment aspects (medication, practical help, meetings with professionals). Each item is rated on a scale from 1 (‘totally dissatisfied’) to 7 (‘totally satisfied’) and followed by a question on whether the patient wants additional help with that domain. Unlike the DIALOG+ intervention, clinicians will be instructed to ask participants to complete the scale at the end of the session, without further discussion and use of the four-stepped solution focused approach.
