Background: The "Signposts for Building Better Behaviour" program, developed by the Parenting Research Centre, Victoria, Australia, was conducted at a public hospital facility in Singapore. Method: More than 1,000 parents completed the program, and filled in questionnaires about their child's behaviours. Results: Parents rated themselves in the questionnaires as being significantly less hassled, stressed, depressed, and anxious after attending the program. They were more confident and satisfied with managing their child, and rated their children's behaviours as having improved. Effect sizes ranged from 0.12 to 0.59. The findings were maintained 3 months after completion of the program. Conclusions: The study provides evidence of the cross-cultural applicability of the principles underlying the Signposts program. As there are long-term repercussions when children's behaviour problems are not dealt with appropriately, such behaviour management programs should be made more available to parents and caregivers.
