Aim: It is well recognised that anxiety is more common in individuals on the autism spectrum in comparison to the general population. Yet, little is known about the personal experiences of anxiety for adults with autism. This qualitative investigation explores the experiences of anxiety for adults on the autism spectrum.\n\nMethod: Semi‐structured interviews were conducted with adults on the autism spectrum. Interviews were digitally recorded and transcribed verbatim. Thematic analysis was used to gain insight into the experiences of anxiety.\n\nResults: We interviewed 10 adults on the autism spectrum with anxiety, six females and four males. Participants were aged between 23 and 68 years old. Themes relating to self‐awareness, impact of anxiety on the individual and management strategies will be presented.\n\nConclusions: The analysis of the qualitative data will provide much needed insight into the experiences of anxiety for adults on the autism spectrum. This information will be used to inform an intervention to improve the health and well‐being of Australian adults on the autism spectrum.
