They also completed the three motivational measures: the TSRQ , PCS Williams et al, 1998), and Change Questionnaire (Wolk & Devlin, 2001). …”

“…These sessions were manualized and closely followed the format of the manual created and utilized for Grilo and Masheb's (2005) study. At the beginning of the second session, participants completed questionnaires assessing motivation for treatment, including the TSRQ , PCS Williams et al, 1998), and Change Questionnaire (Wolk & Devlin, 2001). …”

“…At the beginning of session 6, participants completed questionnaires assessing motivation for treatment, including the TSRQ , PCS Williams et al, 1998), and Change Questionnaire (Wolk & Devlin, 2001). At the final session, participants completed the BDI (Beck et al, 1961), EDE-Q (Fairburn & Beglin, 1994), TFEQ (Stunkard & Messick, 1985), and Q-LES-Q-SF (Endicott et al, 1993).…”

The stage of change measure was administered at baseline and after the first and second MI/traditional motivational sessions.…”
