Autism spectrum quotient, coping with stress and quality of life in a non-clinical sample - an exploratory report.

BACKGROUND

It has been shown that autistic traits may be observed both in individuals with autism spectrum disorders and to a lesser extent in the general population. Since these traits are closely associated with limitations in social functioning, they make development of interpersonal relations difficult, and therefore may have a negative impact on an individual's quality of life (QoL). The purpose of this study was to explore these links, including the mediating effects of coping styles.

METHODS

A sample of 154 adults aged 19-38 years completed three questionnaires: Autism Spectrum Quotient (AQ), Coping Inventory for Stressful Situations and World Health Organization Quality of Life--BREF. Pearson's r correlation coefficients were analysed, followed by path analysis.

RESULTS

All domains of QoL (Physical health, Psychological, Relationships and Environmental) were negatively correlated with AQ. The correlations were low or moderate (from -0.36 to -. 42). AQ was also correlated with two coping styles: positively with Emotion-oriented coping and negatively with Social diversion. Path analysis models showed the mediating effect of coping styles with respect to the relationships between autistic traits and QoL domains. Autistic traits and coping styles explained the greatest level of variance for the Psychological domain (41 %).

CONCLUSIONS

The results confirmed the relationship between autistic traits and QoL, mediated by two coping styles. Due to the small sample and narrow age range of participants, our findings should be treated as a preliminary report.
