Early intensive behavioral intervention for children with autism: parental therapeutic self-efficacy.

Hastings et al. (2002) asked 85 UK moms who run home EIBI programs what helps them feel capable.

The team used a survey. They looked at hours of therapy, how long families had done it, how severe the child’s autism was, and how much support moms got.

They also measured mom stress and ‘therapeutic self-efficacy’—a fancy way to say ‘I believe I can help my child.’

Hours and months of therapy did not predict confidence.

What mattered most was strong program support, lower child symptom severity, and lower mom stress.

Stress acted like a middle-man: when support dropped, stress rose, and confidence fell.

Strauss et al. (2012) extends this view. They tracked kids, not just moms, and showed that low-stress, high-fidelity parents give bigger child gains. The 2002 survey hinted at the pathway; the 2012 study proved it leads to real skills.

Mount et al. (2011) looks like a contradiction. They found most parents do not use the strategies at mastery level even after training. But the two studies measure different things: P et al. asked ‘Do you feel able?’ while R et al. asked ‘Do you actually do it?’ Feeling capable and acting on it are separate steps.

Eldevik et al. (2026) pools 15 trials and shows EIBI works. Their mega-review includes parent-run models like the one P et al. studied, so the confidence question sits inside a program we know is effective.

If you supervise home programs, stop counting hours and start cutting parent stress. Give moms quick-response contact, clear lesson demos, and respite leads. One low-cost move: add a weekly five-minute check-in call focused on mom, not child data. When you lower her stress, her belief in herself—and her teaching quality—rises, and the child’s progress follows.
