Primary Outcome Measures

Name	Time	Method
Overall wellbeing (ORS)<br /><br>To asses change in overall wellbeing, participants will fill in the Outcome Rating Scale (ORS; Miller & Duncan, 2000; Miller, Duncan, Brown, Sparks, & Claud, 2003; Dutch manual by Crouzen, 2010). In phase A1 they will fill it in once every two days, during phase B1 twice a week, during phase B2 and A2 once a week and once at 6 months measurement-FU. Participants will score the ORS with the same frequency as the BTG and NCB, with a total of 53-64 offered measurement points.<br /><br>The ORS is a short, 4-item, self-report instrument measuring individual, interpersonal, and social functioning as well as overall wellbeing on a visual analog scale (VAS). Assessment time is approximately 1 minute or less. The ORS is designed to assess change in patients following psychological intervention. The ORS provides a total score (overall wellbeing) and four sub-scale/item scores. The ORS has adequate psychometric properties (Campbell & Hemsley, 2009).
