Loneliness, friendship, and well-being in adults with autism spectrum disorders.

Mazurek (2014) asked 108 verbally fluent adults with autism to fill out three short forms. One form measured how lonely they felt. One listed their friendships. One tracked emotional well-being.

The team then looked at how the three scores fit together. No therapy was given; it was a one-time survey.

Adults who reported more or better friendships also reported less loneliness. Less loneliness, in turn, went hand-in-hand with better mental health.

Friendships did not have to be large; even one close bond helped.

Lasgaard et al. (2010) saw the same link in teenage boys: more social support meant less loneliness. Mazurek (2014) shows the pattern still holds once those boys grow up.

Redquest et al. (2021) went a step further. In young adults aged 18-25, they showed loneliness is the main bridge between autism traits and later anxiety or depression. The 2014 survey first spotted the bridge; the 2021 study proved most traffic crosses it.

Ratcliffe et al. (2015) extended the idea downward to children. Among 6- to 13-year-olds, weaker social skills predicted more mental-health problems, whether or not the child had intellectual disability. Together the four papers trace one clear line: from childhood through adulthood, social connection protects mental health in autistic people.

If you write goals for teens or adults, do not stop at eye contact or turn-taking. Ask, “Will this help the client make a real friend?” One solid friendship can cut loneliness and boost mood. Track friendship quantity and quality like any other target; both are easy to probe with brief questionnaires. When mental-health symptoms appear, check social isolation first—interventions that build or strengthen friendships may relieve anxiety and depression faster than skills that only reduce autism traits.
