In this pilot study, we examined whether a 2-day Emotion-Focused Family Therapy workshop strengthened parental self-efficacy, satisfaction and beliefs regarding their ability to help their children regulate emotions and reduce the children's symptoms of behavioural- or psychological difficulties. Twenty-three caretakers with 17 children (9 boys) aged 6 to 12 years old completed the workshop. Pre, post and 3-month follow-up data on the Parents' Beliefs About Children's Emotions -- Guidance scale and Parenting Sense of Competence scale, as well as pre and 3-month follow-up data on the Child Behaviour Checklist parent form, were used to assess the effects of the intervention. Parental self-efficacy significantly increased, the caretakers' satisfaction in the parenting role significantly increased but faded after 3 months and the caretakers' beliefs that children can guide their emotions on their own were significantly reduced. Finally, oppositional defiant problems in the children significantly declined.
