As stated in the earlier section entitled SFBT
protocol, the clients were accompanied by a staff
member who supported them during the SFBT trajectory.
The measurements (in both the SBT and
the CAU conditions) were performed by the
therapists/researchers. If necessary, the staff member
assisted the client to understand the questions from
the therapists/researchers by repeating the words or
slightly reformulating them. In addition, staff
members assisted by making the client’s answers
clear to the therapists/researchers by repeating the
words of the client. Following Teall (2000) and
Smith (2006), we reasoned that help from a familiar
person in answering questions and interviewing by a
certified professional (the therapist/researcher)
would lead to more valid responses.
