Using a cross-sectional design, this study explored attachment insecurity and disorganization (assessed using the Strange Situation Procedure) in 90 toddlers (aged 14-24 months) with and without autism traits and assessed the associations between autism traits (severity and profiles) and both developmental level and attachment classification. Our findings showed no significant differences between the rates of attachment insecurity or attachment disorganisation among toddlers with, and toddlers without, autism traits. However, among the toddlers with autism traits, those with a disorganised attachment were more likely to have autism traits of greater severity. While greater autism trait severity was associated with attachment disorganisation, it remains unclear whether this association is the result of children with autism traits having higher rates of attachment disorganisation or whether autism traits are being misinterpreted as attachment disorganisation indices.
