| • Mini-International Neuropsychiatric Interview (MINI; Sheehan et al., 1998a, 1998b). The MINI+ will be used to obtain DSM-IV diagnoses. The validation of the Dutch translation of the clinician rated (CR) version of the MINI (van Vliet & de Beurs, 2007) against the Structured Clinical Interview DSM-III-R-patient version (SCID-P) and the Composite International Diagnostic Interview for ICD-10 (CIDI) showed good to very good kappa values (Sheehan et al., 1998b). • Beck Anxiety Inventory (BAI) (Beck, Epstein, Brown, & Steer, 1988). The BAI is a self-report questionnaire which consists of 21 items, each describing a common symptom of anxiety over the past week on a 4-point likert scale ranging from 0 to 3 (total score is 63). The scale has good internal consistency (0.92) and convergent validity (0.51) and discriminates between depression and anxiety. Test-retest reliability also appeared to be sufficient (0.75). The BAI will be used as primary outcome measure. | — |

| • Fear Questionnaire (FQ) (Marks & Matthews, 1979). This self-report questionnaire consists of 3 subscales (agoraphobia, social phobia and blood/injury dimensions). Besides these subscales the FQ also incorporates one scale assessing severity of avoidance behavior, how troublesome and disturbing/disabling the present symptoms are according to the patient. A Dutch validation study showed that all scales have sufficient internal consistency and convergent and discriminate validity (van Zuuren, 1988). • Beck Depression Inventory-II (BDI-II) (Beck, Erbaugh, Ward, Mock, & Mendelsohn, 1961; Beck, Steer, Ball, & Ranieri, 1996). The BDI is a self-report questionnaire and consists of 21 items (rated 0 to 3), each describing a depressive symptom in four levels of severity. Total scores range from 0 to 63. The BDI-II has high internal consistency with a Cronbach*s alpha of .91 (Beck et al., 1996; van der Does, 2002). • World Health Organization Quality of Life - Bref (WHOQOL-Bref) (Trompenaars, Masthoff, Van-Heck, Hodiamont, & De-Vries, 2005). The WHOQOL-Bref was developed as an international cross-culturally comparable self-report quality of life assessment instrument. It assesses the individual's perceptions of quality of life in the context of their culture and value systems, personal goals, standards and concerns across 4 domains: physical health, psychological health, social relationships, and environment. The internal consistency of the four domains of the WHOQOL-Bref ranged from 0.66 to 0.80. Domain scores of the WHOQOL-Bref correlated around 0.92 with the WHOQOL-100 domain scores. Relatively low correlations were found between demographic characteristics (age and sex) and WHOQOL-Bref domain scores. It is concluded that the content validity, construct validity, and the reliability of the WHOQOL-Bref in a population of adult Dutch psychiatric outpatients are good (Trompenaars et al., 2005).
