The process of getting an autism diagnosis can be a stressful and uncertain time for families. While the experiences of parents seeking an autism diagnosis for their child have been explored in previous research, the experiences of families with a daughter have been underrepresented. It is likely that their experience is markedly different given that females are often misdiagnosed and/or are diagnosed at a later age. Semi-structured interviews were conducted with six families, and interpretative phenomenological analysis was used along with member checks to derive themes from the participants' narratives. Three superordinate themes emerged from the analysis: 'Something's not right' consisted of narratives describing the process of getting their daughter diagnosed and 'So many barriers' captured the factors that delayed assessment and diagnosis. Finally, the third theme 'I wanted to just get this process done and dusted' explored the range of emotions experienced by families during the assessment process. The importance of challenging outdated conceptualisations of autism and providing further training to increase health professionals' confidence when diagnosing autistic females is emphasised, as well as recognising that families may experience a range of emotions during the assessment and diagnostic process, including positive ones.
