Social Anxiety
Conditions
Brief summary
The present study examines whether a self-help app can reduce symptoms of social anxiety disorder.
Detailed description
The study will test the effectiveness of a newly developed mobile app in treating patients with social anxiety. Participants will be randomly assigned to one of the following groups: app use only, therapist-guided app use, and a wait-list control group. Over a 12-week period, the study will examine whether mobile app use leads to significant reductions in symptoms associated with social anxiety, as well as improvements in secondary outcomes such as quality of life, depression, or psychological impairment.
Interventions
BEHAVIORALSelf-help Smartphone App
The app provides a 12-week adaptation of scientifically proven cognitive behavioral therapy techniques for the treatment of SAD and is intended for use as a mobile intervention. The app includes modules such as learning (e.g., creating a model, learning about the maintaining factors), changing the maintaining factors (e.g., safety behaviors), or behavioral experiments.
BEHAVIORALTherapist-guided App Use
In addition to using the app, patients receive a total of 8 video-based therapy sessions over the course of 12 weeks. The sessions include topics such as video feedback and behavioral experiments.

Masking description
Outcome assessors are blinded to the conditions, but blinding of participant and care provider is not possible due to the nature of the intervention.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Change in SAD-related symptom severity measured by the Liebowitz Social Anxiety Scale | change from baseline (week 0) to week 12 (post) and to week 36 (follow-up) | The LSAS is a clinician-rated interview designed to measure fear and avoidance in different social situations. The situations are rated on scale from 0 (not at all or never) to 3 (severe or most of the time), with higher scores indicating greater symptoms of social anxiety. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Change in the Social Phobic Cognition Questionnaire (SPK) | change from baseline to week 12 (post) and to week 36 (follow-up) | The SPK lists 22 SAD-related beliefs that are rated on two scales: thought frequency, ranging from 1 (thought never occurs) to 5 (thought always occurs) and belief rating, ranging from 0 (I do not believe this thought) to 100 (I am completely convinced this thought is true). Higher scores indicate more SAD-related beliefs. |
| Pain and Disability Index (PDI) | change from baseline to week 12 (post) and to week 36 (follow-up) | The PDI measures the amount of impairment and distress caused by the mental illness. It consists of 7 different categories (e.g., Social Activity) that are rated on a scale fom 0 (no disability) to 10 (total disability). Higher scores indicating higher levels of disability. |
| Beck Depression Inventory - Fast Screen (BDI-FS) | change from baseline to week 12 (post) and to week 36 (follow-up) | The BDI-FS assesses symptoms of depression using 7 items on a 4-point scale, with higher scores indicating greater severity. |
| World Health Organization Quality of Life (WHO-QOL-BREF) | change from baseline to week 12 (post) and to week 36 (follow-up) | The WHO-QOL-BREF measures the overall quality of life and asks for ratings on varying 5-point-scales for different domains like physical health (e.g., how satisfied are you with...). Scores for each domain are transformed to a scale of 0 to 100, with higher overall scores indicating a higher quality of life. |
| Brief Symptom Inventory - 18-item version (BSI-18) | change from baseline to week 12 (post) and to week 36 (follow-up) | The BSI measures general psychological distress using 18 items like feelings of loneliness on a scale from 0 (not at all) to 4 (a lot). |
| Anticipatory and Consummatory Interpersonal Pleasure Scale (ACIPS) | change from baseline to week 12 (post) and to week 36 (follow-up) | The ACIPS measures the pleasure a person experiences in a social situation with a total of 17 items. The items are rated on a scale from 1 (very false for me) to 6 (very true for me), with higher total scores indicating higher interpersonal pleasure. |
| Social Pain Questionnaire-5 (SPQ-5) | baseline measurement only (week 0) before intervention starts | Sensitivity to rejection in social situations are assessed with the Social Pain Questionnaire (SPQ-5). The questionnaire consists of 5 items rating from 0 (describes me perfectly) to 4 (not at all). Higher total scores indicate higher social pain. |
| Change in SAD-related symptoms measured by the Social Phobia Inventory (SPIN) | change from baseline to week 12 (post) and to week 36 (follow-up) | The SPIN is a self-report questionnaire designed to assess the amount of discomfort in different situations during the last week. The scale ranges from 0 (not at all) to 4 (extremely). The total score ranges from 0 to 68, with higher scores indicating more severe symptoms of social anxiety. |
| self-developed question regarding the attitude towards online interventions | baseline measurement only (week 0) before intervention starts | To assess a person's attitude toward online circumvention, a question is asked that is rated on a scale of 0 (not helpful at all) to 100 (extremely helpful), with higher scores indicating higher positive expectations. We hypothesize that this variable could moderate the outcome effects. |
| Client Satisfaction Questionnaire (CSQ) | Only post measurement (week 12) | Treatment satisfaction will be measured by using the Client Satisfaction Questionnaire (CSQ), which we adapted slightly to match the use of the app. The questionnaire consists of 8 questions rated on a scale from 1 (not at all) to 4 (definitely yes). |
| Self-developed questionnaire on negative effects of treatment | Only post measurement (week 12) | Drawing on the results of Boettcher et al., we developed a brief (7-item) scale with items covering the negative side effects that were considered most relevant by a group of experts. The items are rated on a scale from 0 (do not agree at all) to 5 (fully agree). Please note, that the descriptive list of possible side effects is preliminary and may be slightly revised after the pilot study. As the list contains an open item, responses to this item will be evaluated after the pilot study and inclusion of further side effects in the list is possible should they be mentioned frequently. |
| Clinical Global Impression (CGI) | change from baseline to week 12 (post) and to week 36 (follow-up) | 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 and its practicability. |
| Quick Inventory of Depressive Symptoms (QIDS-C) | change from baseline to week 12 (post) and to week 36 (follow-up) | The Quick Inventory of Depressive Symptomatology (QIDS-C) is a 16-item rating instrument for the assessment of depressive symptoms by an independent interviewer. |
| Structured Clinical Interview for DSM 5 SCID-V-CV | change from baseline to week 12 (post) and to week 36 (follow-up) | Structured interview providing a formal diagnosis. Psychometric properties showed good reliability and specificity. |
| Modified version of the Social Phobia Weekly Summary Scale (SPWSS) | weekly questionnaire from baseline to week 12 (post), as well as assessments at baseline, 6 weeks (mid), 12 weeks (post), and 36 weeks (follow-up) | Social anxiety and social approach behavior will be measured using a modified version of the Social Phobia Weekly Summary Scale (SPWSS). The individual points are rated on a scale from 0 to 100, with higher values indicating a higher rating of the respective item. |
| Self-developed question regarding skills in using the Internet | baseline measurement only (week 0) before intervention starts | A single question assesses participants' ability to use smartphone apps on a scale of 0 to 100, with higher scores indicating greater ability to use apps on the smartphone. We hypothesize that this variable could moderate the outcome effects. |
