Severity of cluster C PD (SCID-5-PD) To asses and evaluate change in cluster C PD severity at 6 months measurement--FU (compared to before baseline), the Structured Clinical Interview for DSM-5 personality disorders (SCID-5-PD; First, Williams, Benjamin & Spitzer, 2015; Dutch translation Arntz, Kamphuis & Derks, 2017) will be administered.

Participants will score their goals with the same frequency as the ORS and NCB, with a total of 53-64 offered measurement points. At 6 months measurement-FU, qualitative information about participants* experience with setting, tracking and evaluating goals will be gathered during a 15 minutes open-question interview. Negative Core Beliefs (NCB) To asses change in credibility of Negative Core Beliefs (NCB) after pre-treatment, treatment, 3 months treatment-FU and at 6 months measurement-FU (compared to baseline), participants will rate the credibility of their two most prominent negative core beliefs on a VAS of 0-100%, with the same frequency as the ORS and BTG, with a total of 53-64 offered measurement points.
