The interview will include the Structured Clinical Interview for DSM 5 (SCID-5) [54 ] conducted by clinician independent raters. Psychometric properties showed good reliability and specificity [55 (link)].
To screen for borderline personality disorder (BPD), we use a set of 5 questions suggested by Wongpakaran et al. [56 (link)] that screen for symptoms of BPD based on the DSM-V and a Rasch analysis. It showed good quality for assessing BPD [56 (link)]. If screening indicates that BPD may be present, we use the appropriate category of the SCID-5 to check for the other criteria of BPD.
We further use the Clinical Global Impression (CGI) [57 ] modified for patients with SAD. The CGI-Severity scale provides information about the current severity of social phobic symptoms which are rated on a 7-step scale from “normal” or “not ill at all” to “among the most severely ill patients” by a clinician. The CGI-Improvement scale is a 7-point scale rating the change in symptom severity from ‘improved by a lot’ to “a lot worse.” The use of the CGI, as a measure for symptom-specific improvement for patients with SAD, is supported by adequate psychometric properties [58 (link)] and its practicality.
Finally, the Quick Inventory of Depressive Symptomatology (QIDS-C) [59 (link)] will be applied, a 16-item rating instrument for the assessment of depressive symptoms by an independent interviewer, which showed acceptable internal consistency and treatment sensitivity [60 (link)]. Figure2 gives an overview of the measures and assessments used in this study.![]()
