Preventing anxiety in the children of anxious parents - feasibility of a brief, online, group intervention for parents of one- to three-year-olds.

The online group intervention was feasible and acceptable. There were moderate to large effects on parental mental health and no adverse effects on children (decline on outcome measures). This indicates that intervening early in parenting with anxious parents is possible and warrants further investigation to establish prevention efficacy with a larger, controlled trial.
