This dataset was generated to examine the extent to which GPs experience barriers and facilitators to identifying, managing and accessing specialist services for these disorders, as well as factors associated with GPs' confidence. It contains a cross-sectional, self-report questionnaire in primary care, addressing identification, management and access to specialist services for children (under 12 years) with anxiety disorders, using a five point Likert scale. Some demographic information was provided by GPs. The participants were 971 GPs in England.
