There is a paucity of research studying the experiences of peri/menopause 2. In a female-dominated profession such as clinical psychology, peri/menopause is likely to impact on clinical psychologists’ (CPs’) professional practice. This study aims to explore female CPs’ experiences of peri/menopause and how this impacts their professional practice. Ten interviews with female UK-trained CPs were analysed using an interpretative phenomenological analysis. Three superordinate and six subordinate group experiential themes were identified: Perimenopause threatening professional identity (“What is happening to me?”, “Am I just being lazy?”, “Just keep going”), The multiplicity of peri/menopause (“It’s like having another job”, “The hormonal woman”, Gains and losses of ageing), and The value of sharing lived experience. This study adds to the understanding of how peri/menopause impacts on women’s professional lives. It highlights the need to consider peri/menopause as a potential barrier to career progression in female-dominated professions, such as clinical psychology.
