Background: We developed the Italian version of the adult developmental co-ordination disorders/dyspraxia checklist (ADC), providing reliability and concurrent validity data for the scale (Aim 1). In addition, we investigated the relationships between motor coordination difficulties and different autistic traits (Aim 2). Methods: 498 participants (341 females; age range = 18–34) underwent the Italian version of the ADC, as well as a handwriting speed test, the autism spectrum quotient, the empathy quotient, and the systemizing quotient. Results: The distinction between three main factors (A, B, and C) identified in the original version of the ADC was confirmed here. Internal consistency of the ADC subscales was adequate, as well as the correlation with the handwriting speed test used to assess concurrent validity. No substantial sex differences on the ADC scores were found. Furthermore, data revealed that poor autistic-related communication skills and lower levels of systemizing tendencies were, among all the investigated autistic traits, those more strongly associated with higher motor coordination difficulties. Conclusions: The Italian ADC seems a valuable tool for assessing motor coordination difficulties in adults and can reveal the nuanced impact exerted by different autistic traits on self-reported motor functioning.

Objective To explore the ramifications of childhood motor difficulties, providing insights into their impact and consequences over time. Design A qualitative study using semistructured individual interviews. Data were analysed using systematic text condensation. Setting Neonatal intensive care recipients born at Uppsala University Children’s Hospital, Uppsala, Sweden, between 1986 and 1989, were enrolled in a longitudinal follow-up study and subsequently interviewed in 2019–2020. Participants 13 individuals in their early 30s, who met the criteria for developmental coordination disorder or performed below the 5th percentile on motor tests at 6.5 years of age, were interviewed. Those with co-occurring deficits in attention or social behavioural at age 6.5 were excluded. Results Two themes emerged: (1) lifelong challenges and (2) navigating the journey of motor difficulties: support, awareness and confidence. Five participants reported persistent motor difficulties. They adapted and integrated these challenges into their daily lives without feeling constrained. Parental support was crucial to their success, whereas support from schools was limited. Conclusion Adults who faced motor difficulties in childhood developed effective coping strategies, overcame challenges and now lead fulfilling lives. The findings stress the importance of parental support and understanding, addressing contextual factors and fostering positive attitudes and supportive environments to enhance well-being and participation.
