However, empirical evidence to date has been mixed, with some studies reporting lower levels of social reward in individuals with Autism Spectrum Disorder (ASD), and others finding no difference when compared to typically developing controls. Alexithymia, a subclinical condition associated with the reduced ability to identify and describe one's own emotions, has been found to account for other affective difficulties observed inconsistently in individuals with ASD. The current study used a nonclinical sample (N = 472) to explore the associations between autistic traits and the value of six types of social reward, as measured by the Social Reward Questionnaire. In addition, we measured alexithymia to assess if this accounted for associations between autistic traits and social reward. There were three main findings. Firstly, higher levels of autistic traits were associated with significantly less enjoyment of admiration and sociability, and adding alexithymia to these models did not account for any additional variance. Secondly, both autistic traits and alexithymia were uniquely associated with reduced levels of enjoyment of prosocial interactions and sexual relationships. Thirdly, autistic traits were associated with higher levels of enjoyment of passivity and negative social potency, but these associations were no longer significant once alexithymia was taken into account, suggesting that co-occurring alexithymia accounted for these apparent associations. Overall, the current findings provide a novel and more nuanced picture of the relationship between autistic traits and social reward. date: 2015-04-08 official_url: http://dx.doi.org/10.1371/journal.pone.0121018 oa_status: green full_text_type: pub language: eng primo: open primo_central: open_green article_type_text: Journal Article verified: verified_manual elements_source: PubMed elements_id: 1026723 doi: 10.1371/journal.pone.0121018 pii: PONE-D-14-46498 lyricists_name: Foulkes, Lucy lyricists_name: McCrory, Eamon lyricists_name: Viding, Essi lyricists_id: FOULK91 lyricists_id: EJMCC66 lyricists_id: EVIDI50 full_text_status: public publication: PLoS One volume: 10 number: 4 article_number: e0121018 event_location: United States citation: Foulkes, L; Bird, G; Gökçen, E; McCrory, E; Viding, E; (2015) Common and distinct impacts of autistic traits and alexithymia on social reward.
