About

This study aims to investigate whether reductions in negative interpretation biases, induced via an experimental manipulation (Cognitive Bias Modification for Interpretation; CBM-I), lead to reductions in symptoms of social anxiety amongst individuals experiencing high levels of social anxiety. The study further aims to investigate the relationship between multifaceted measures of interpretation bias, psychopathological symptoms, neurophysiological indices, behavioral indices of stress reactivity, and SAD symptoms.

To achieve these aims a sample of individuals experiencing high levels of social anxiety will be recruited. After completing multi-faceted measures of interpretation bias, including neurophysiological indices, participants will be randomized to complete an online one-week daily CBM-I or sham training control condition training schedule. Following the one week training, individuals will return to the lab to complete further multi-faceted measures of interpretation bias and social anxiety symptoms. One week after this (i.e. 2 weeks post-basline), participants will complete a final set of symptom and bias measures online.

Enrollment: 85 patients

Sex: All

Ages: 18 to 65 years old

Volunteers: Accepts Healthy Volunteers

Inclusion criteria

• Provides informed consent
• Sufficient German language skills to complete the experimental tasks and questionnaires
• Aged between 18 and 65 years
• Scoring ≥ 52 on the SPAI-G (Turner et al., 1989; Fydrich, 2016), indicating elevated levels of social anxiety
• Lives within reasonable travelling distance of the research centre

Exclusion criteria

• Current psychotherapeutic treatment or psychotherapeutic treatment completed within the last 6 months prior to study enrolment.
• Current substance misuse or dependency (apart from Nicotine)
• Acute suicidality or self-harm
• Symptoms of a psychotic or bipolar disorder
• Presence of a somatic condition that could systematically affect cortisol levels (in particular: Pregnancy and lactation, adrenal dysfunction, thyroid dysfunction, pituitary dysfunction)
• Presence of a somatic condition that could systematically affect brain physiology (current or anamnestic neurological disorders, in particular: anamnestic traumatic brain injury, epilepsy, multiple sclerosis, brain tumors)
• Presence of a somatic condition that could systematically affect peripheral physiological measures (in particular: cardiovascular diseases (e.g., cardiac arrhythmias, circulatory diseases [e.g., hypertension]))
• Sensitivity or alteration of skin surface providing contraindication for EEG or periphysiological measures (in particular: baldness, dreadlocks, open wounds on the head or facial surface, skin conditions that cause particular sensitivity to gels and creams)

Cognitive Bias Modification for Interpretation (CBM-I)

Experimental group

Description:

Participants in this arm complete an initial introductory session of Cognitive Bias Modification for Interpretation (CBM-I) in the lab followed by 6 sessions scheduled to be completed over the subsequent week (1 per day). CBM-I will be administered via an online platform using an individual login account.

Behavioral: Cognitive Bias Modification for Interpretation (CBM-I)

Sham Training Control Condition

Sham Comparator group

Description:

Participants in this arm complete an initial introductory session of the sham training control condition in the lab followed by 6 sessions scheduled to be completed over the subsequent week (1 per day). CBM-I will be administered via an online platform using an individual login account.

Treatment:

Behavioral: Sham Training Control Condition
