Design outcomes

Primary

MeasureTime frame
The primary outcome refers to disorder-specific anxiety symptomatology (RCT-S: Liebowitz Social Anxiety Scale (LSAS); RCT-P and RCT-A: Panic and Agoraphobia Scale (PAS)) after 12 weeks. Liebowitz Social Anxiety Scale (LSAS-SR; Baker et al., 2002): The LSAS is a self-report instrument designed to measure the severity of social phobia (T0, T1, T2). Panic and Agoraphobia Scale (PAS; Bandelow, 1995): The PAS measures symptoms of panic disorder and agoraphobia within the past week. Thirteen items are used to assess five domains that limit quality of life in patients with panic disorder: panic attacks, agoraphobic avoidance, anticipatory anxiety, restriction, and health fears (T0, T1, T2).

Secondary

MeasureTime frame
Patient Health Questionnaire (PHQ-9; Kroenke et al., 2001): The PHQ-9 is the depression module of the PHQ-D and measures the presence and frequency of nine depressive symptoms (according to DSM-IV criteria for major depression) during the past two weeks (T0, T1, T2). Perceived Health Competence Scale (PHCS; Smith et al., 1995): The PHCS measures subjective health competence in self-report. The questionnaire was originally designed for the somatic domain and was adapted for mental health for the planned study (T0, T1, T2). Work and Social Adjustment Scale (WSAS; Mundt et al., 2002): The WSAS uses five items in self-report to assess functional impairment due to a specific problem in daily life (T0, T1, T2). Short scale for measuring general self-efficacy beliefs (ASKU; Beierlein et al., 2013): The ASKU is used to assess self-assessment of one's self-efficacy competence with three items (T0, T1, T2). Treatment Adherence Perception Questionnaire (TAPQ; Sanford & Rivers, 2020): The TAPQ measures patients' adherence to learned strategies. Originally developed for the somatic domain, the questionnaire was adapted specifically for the planned study for the psychiatric domain (T1, T2). Timeline Followback (TLFB; Carey et al., 2001): The TLFB is a method for retrospectively recording daily alcohol or drug use. For the present study, the online version of the TLFB was adapted for anxiety disorders and surveys the occurrence of panic attacks, anxiety symptoms, and depression symptoms in the past 6 weeks (T1, T2). Relapses: Patient's relapses are assessed using the Reliable Change Index (RCI). The RCI is a measure calculated to survey significant changes (worsening) in an individual's measures. The RCI is calculated using measures of the primary endpoints (PAS and LSAS). In addition, contacts to the health care system are assessed (e.g., of (partial) inpatient admissions, somatic evaluations) to survey relapse (T1, T2). Client Satisfaction Questionnaire (CSQ-8; Sc
