In both conditions, three data measurements were
taken: the first immediately before SFBT; the
second immediately after SFBT and the third, a
follow-up measurement, 6 weeks after SFBT. Three
measurements were also taken in the CAU group:
the first baseline measurement; the second measurement
after 15 weeks (the mean length of all SFBT
treatments) and the third, a follow-up measurement
after 15 + 6 = 21 weeks. The two solution-focused

on SFBT included the history and philosophy
of SFBT, the tenets of SFBT, the session
format and structure of SFBT, video examples from
the developers of SFBT, role playing and supervised
practice using SBFT with clients with ID
