The relation between insecure general attachment and social anxiety has long been established.

To explore the associations between social interaction and performance anxiety and avoidance, attachment styles, and parental marital status.

146 Portuguese adolescents, with a mean age of 18.99 years old (SD = .848; range: 18-20), filled in the Social Interaction and Performance Anxiety and Avoidance Scale and the Experiences in Close Relationships-Relationship Structures Questionnaire.

Distress/Anxiety was correlated with avoidance attachment to mother and father (rs = .17*, p = .04; rs = .18*, p = .03), to anxious attachment to romantic partner (rs = .21*, p = .01), and to anxious and avoidance attachment to best friend (rs = .25**, p = .00; (rs = .17*, p = .035). Avoidance was significantly correlated with avoidance to father and to romantic partner (rs = .18*, p = .03), and to anxious and avoidance attachment to best friend (rs = .21**, p = .009; rs = .18*, p = .03). A significant difference was found in avoidance attachment to father X2 = 10.246 (4, n = 146), p = .036, by parental marital status, with the adolescents with single/divorced parents presenting a higher mean score (Md = 111.10; Md = 82.93) than the other groups.

Distress/anxiety seems to be associated with more close relationships, and a single/divorced status with Avoidance. Longitudinal studies are needed to explore if insecure attachment to parents predicts insecure extra-familiar attachment, and to explore the long-term effects of parental marital status.
