Evaluation of a parent-training manual for reducing children's fear of the dark.

The team mailed parents a short manual. It told them how to help kids face the dark.

Six children, ages 3 to 11, joined the test. Parents worked at home for two weeks.

The book mixed three tools: slow exposure, praise, and kid self-talk. No clinic visits needed.

Every child reached the goal: staying alone in a dark room. All said fear was gone.

Three-month, six-month, and one-year checks showed the gains held or got better.

SRieth et al. (2022) later copied the idea for dog phobia. They swapped the manual for a storybook plus short video calls. Big fear drops still came in four weeks.

Hilton et al. (2010) tested a self-read parenting book for defiant behavior. Their effect was small, while E et al. saw large drops. The difference: fear is easier to measure and parents stuck to the dark plan exactly.

Wing (1981) did the same kind of parent-led exposure, but with kids who had ID and feared strangers. Both studies used moms, multiple baselines, and six-month follow-ups. E et al. widened the idea to typical kids and a new fear.

You can hand parents a slim manual and end a common phobia in days. No office space, no long wait list. Try it next time a family asks for night-light help.
