Social interpersonal touch is an important part of nonverbal communication and mediates human bonding. However, one's attitude towards touch is highly individual, and touch is not always perceived as pleasant. For instance, socially anxious people show less touch comfort and higher touch avoidance than socially extroverted people. To investigate which aspects of touch attitude relate to symptoms of social anxiety, we adapted the "Social Touch Questionnaire" (STQ) to the German-speaking population and related it to the "Brief Fear of Negative Evaluation Scale" which assesses symptoms related to social anxiety. In a sample of 479 students, validation of the STQ disclosed good reliability and internal consistency. Exploratory factor analysis conducted in half of the sample revealed a three-factor model and suggested shortening the STQ for higher quality. Confirmatory factor analysis in the other half supported these findings. Subscale analyses revealed a correlation between symptoms of social anxiety and dislike of social touch but not between the former and liking of social touch. Overall, touch is an important channel of social communication which individuals with symptoms of social anxiety seem hindered to benefit from. Screening for this issue via the shortened STQ might provide supporting information for therapists. To investigate the transferability of the STQ as a screening tool for daily clinical practice, we suggest further research in clinical samples.
