Men’s experiences with anxiety are under-researched and poorly understood. Existing research gives little indication of how men talk about anxiety in situ, and little is known about how men describe their experiences of anxiety. Online discussion forums provide an opportunity to conduct naturalistic observations of how men describe their experiences with anxiety without the influence of a researcher. Thematic analysis, informed by principles of discursive psychology, was used to examine 130 opening posts to an online anxiety discussion forum. One superordinate theme, where anxiety is constructed as a loss of control, was identified. Analysis of this overarching theme generated three themes relating to how posters described a loss of control: (a) anxiety as an immobilizing force, (b) anxiety as an independent entity, and (c) anxiety as a dualist construction of the self. Our analysis has clear implications for developing and improving interventions for men experiencing anxiety.
