Hong, Jinkuk; Bishop-Fitzpatrick, Lauren; Smith, Leann E.; Greenberg, Jan S.; Mailick, Marsha R. – Journal of Autism and Developmental Disorders, 2016
We examined factors related to subjective quality of life (QoL) of adults with autism spectrum disorder (ASD) aged 25-55 (n = 60), using the World Health Organization Quality of Life measure (WHOQOL-BREF). We used three different assessment methods: adult self-report, maternal proxy-report, and maternal report. Reliability analysis showed that…
