WITHDRAWN: Improving the Measurement of Alexithymia in Autistic Adults: A Psychometric Investigation and Refinement of the Twenty-item Toronto Alexithymia Scale

Abstract: Background: Alexithymia, a personality trait characterized by difficulties interpreting one’s own emotional states, is commonly elevated in autistic adults, and a growing body of literature suggests that this trait underlies a number of cognitive and emotional differences previously attributed to autism, such as difficulties in facial emotion recognition and reduced empathy. Although questionnaires such as the twenty-item Toronto Alexithymia Scale (TAS-20) are frequently used to measure alexithymia in the auti… Show more

“…Data were collected during early 2019 as part of a larger survey study on repetitive thinking in autistic adults (project number RM0030Gotham). Data from this larger cohort have been reported in several previous publications (Williams et al, 2020; Williams, Everaert, & Gotham, 2021; Williams & Gotham, 2020a, 2020b). Participants were compensated $50 in Amazon gift cards for completion of the study.…”

“…Depression and anxiety symptoms were quantified using the Beck Depression Inventory–II autism‐specific T‐score (Williams, Everaert, & Gotham, 2021) and generalized anxiety disorder–7 (GAD‐7) total score (Kroenke et al, 2010), respectively. Trait neuroticism was measured using a 10‐item scale derived from the international personality item pool (Goldberg et al, 2006), which we refer to as the IPIP‐N10 (Williams & Gotham, 2020b). Lastly, trait alexithymia was measured using the eight‐item general alexithymia factor score T‐score derived from the twenty‐item Toronto Alexithymia Scale (GAFS‐8; Williams & Gotham, 2020b), which is the only alexithymia score to be thoroughly validated in the autistic population to date.…”

“…Second, the measure of alexithymia used in Study 1, the TAS‐20, has potential issues. It may measure psychological distress rather than alexithymia specifically (Preece et al., 2020) and its factorial validity has been questioned in both autistic and non‐autistic samples (e.g., Tuliao et al., 2020; Williams & Gotham, 2021).…”

“…Addressing the limitations of Study 1, we aimed to replicate and extend our findings in a large representative UK sample of 18‐25‐year‐olds. Specifically, we aimed to conduct a pre‐registered conceptual replication of Study 1, utilising a subset of 8 items from the TAS‐20 alexithymia measure that are purported to be equally, and potentially more, appropriate for studying autism‐related emotional difficulties (Williams & Gotham, 2021). Conceptual replications, where the same research question is addressed using a different methodology, are increasingly used in autism research to test the robustness of findings (e.g., Clutterbuck, Callan, et al., 2021; Taylor et al., 2021).…”
