Plain English Summary

Background and study aims
The Enhancing Parenting Skills (EPaS) 2014 programme is an 8 session course for professionals that work with children and families. It aims to improve the knowledge and ability of professionals in cases where the child has behavioural problems. This study was set up to determine as to whether the programme is effective in dealing with these problems. Previous studies have shown that participation in the programme does result in improvement in child behaviour. However, the number of families and health visitors that have taken part have been small so far. Here, we will recruit a larger sample of families and health visitors for the study.

Who can participate?
Parents of children aged 2.5 - 4 years who score within the clinical range on a child behaviour questionnaire (Eyberg Child Behaviour Inventory). Parents and children must speak Welsh and/or English.

What does the study involve?
We are recruiting health visitors to complete a 3-day training in the EPaS 2014 programme. Each health visitor finds two families from their caseload to participate in the study. Potential families are asked to complete a questionnaire about their child's behaviour and, if the child has a high Eyberg Child Behaviour Inventory score, are invited to participate in the study. A researcher then contacts the family to arrange a home visit to collect information for the trial (data collection). Families are given an information sheet to read and, if they are happy to take part, a consent sheet to sign. They are then asked to complete a number of questionnaires and a 30-minute observation session. During the observation session, the researcher observes the interaction between the parent and child whilst they are completing a play task chosen by the child. Following the initial data collection visit (known as baseline), families are randomly allocated to either the treatment group or a wait-list control group, ensuring that each health visitor has on treatment family and one control family. Treatment families complete the EPaS 2014 programme immediately, whilst control families are offered the programme 4-months later when the first follow-up data collection visits have been completed. Health visitors will complete a 3-day training in the EPaS 2014 programme (one day every month for 3 months) whilst working with their treatment family. Every family is required to complete the baseline data collection visit and a 4-month follow-up visit, which is the same as the initial visit. Treatment families are also asked to complete a 8-month follow-up visit, which is the same as the other data collection visits.

What are the possible benefits and risks of participating?
By participating in the study there is an opportunity to get support for their child's behaviour problems that has been shown to be effective in previous studies. All participants will be given access to the programme, although for some participants this will be after the second follow-up data collection point rather than at the beginning. There are no obvious risks to participants.

Conduct Disorder, child behaviour problems


The families are randomised to two groups: one receives the intervention immediately and the other receives the intervention after a four-month waiting period.
The Enhancing Parenting Skills (EPaS) 2014 programme is a one-to-one intervention delivered by health visitors to parents of a child with behaviour problems. Training for health visitors includes assessment methods, case analysis, and intervention strategies. The intervention is delivered in weekly home visits for 10-12 weeks. Each health visitor will deliver the intervention to two families; one immediately and one after the 4-month follow-up assessment (wait-list control group). Intervention families will have three data collection points: baseline, 4 months and 8 months. Wait-list control families will only undertake two data collection points: baseline and 4-month follow-up.
