Abstract
Background
Self-determination, described broadly as experiencing causal agency, is positively associated with quality of life (QoL) and increases through satisfaction of three basic psychological needs: autonomy (feeling able to make choices free from pressure), competence (perceived self-efficacy), and relatedness (social connection). Both unsupportive environments and challenges with social interaction can interfere with satisfaction of psychological needs. Social challenges are a key trait for autism diagnosis, and unsupportive environments are also known to adversely affect QoL for autistic people. Autistic people report, on average, lower self-determination than non-autistic people. Therefore, it is hypothesized that higher levels of autistic traits may reduce opportunities to develop self-determination, affecting QoL.
Methods
We tested a parallel indirect effects model where we hypothesized that the relationships between autistic traits and four domains of QoL (psychological, social, physical, and environmental) would be indirectly influenced through self-determination (represented through satisfaction of the basic psychological needs for autonomy, competence, and relatedness). This study drew participants from the general population (N = 262; M AGE = 37.6, standard deviation = 11.92; 1.9% reported an autism diagnosis and 2.7% identified as autistic without a diagnosis). Participants completed an online survey.
Results
Higher levels of autistic traits were associated with lower levels of self-determination and lower levels of QoL, and there was a significant indirect effect between autistic traits and QoL via self-determination. More specifically, we found a significant indirect effect between autistic traits and all QoL domains via competence; between autistic traits and the environmental, social, and psychological QoL domains via relatedness; and between autistic traits and the physical and environmental QoL domains through autonomy.
Conclusions
Our results suggest that supporting satisfaction of the needs for autonomy, competence, and relatedness may represent an important element in designing effective programs to support the development of self-determination in people with higher levels of autistic traits (potentially including autistic individuals) and also to support these people to improve their QoL.
