Background: There is co-morbidity between parental depression and childhood conduct disorder. The Incredible Years (IY) parenting programmes reduce both conduct disorder in children and depression in their parents. Recent U.K. and Ireland trials of the effectiveness and cost-effectiveness of IY parenting programmes have assessed children's health and social care service use, but little is known about the programme's impact on parental service use. This paper explores whether an above clinical cut-off score on the Beck Depression Inventory II (BDI II) is associated with high or low parental health and social care service use in high-risk families receiving the IY Basic Programme., Methods: This is a secondary analysis of a subsample (N = 119) from the first U.K. community-based randomised controlled trial of the 12-week IY Basic Programme (N = 153). Parents with children at risk of developing conduct disorder were randomised to receive the programme or to a waiting-list control group. BDI II total and BDI II clinical depression cut-off scores were compared to frequencies and costs of parents' service use, at baseline, six, twelve and eighteen months post-baseline for the intervention group and at baseline and six months post-baseline for the control group., Results: Intervention group parents who scored above the clinical cut-off on the BDI II at baseline used more health and social care services than those who scored below at baseline, six and eighteen months. Significant reductions in service use frequencies were found for the intervention group only., Conclusion: Parents with higher levels or depression used more health and social care service and parenting programmes have been shown to reduce parental depression and also health and social service use. However, further exploration of depressed parents' service use and the cost implications for publically funded health and social care services is needed.

Conduct disorder (CD) places huge costs on the individual, family and society. Parenting programmes can reduce CD symptomatology, but economic evaluations of their cost-effectiveness are rarely undertaken. The objective of this paper was to conduct the first specific systematic review of the published economic evidence of parenting programmes as a means to support families with children with or at risk of developing CD. A systematic search of 12 electronic databases was conducted. We identified 93 papers, of which six fulfilled the inclusion criteria. The search found one review article, mainly focusing upon clinical evidence with secondary focus on cost-effectiveness, one cost-effectiveness study, two partial economic evaluations and two cost studies. The costs of group parenting programme delivery ranged from £629.00 to £3839.00. Cost-effectiveness was influenced by intervention type and delivery method, i.e. individual versus group programme. The review highlights a need for a more standardized approach towards the comparison of the cost-effectiveness of parent programmes. In future studies it may be helpful to adopt a 'complex intervention approach', exploring in detail the attribution of cause and effect, the role of socio-economic setting and ripple effects, e.g. benefits to other family members., (© 2011 Blackwell Publishing Ltd.)

Background: the incidence of conduct disorder in young children is 10% in the general population and 37% among fostered children. Up to 40% of untreated children diagnosed with conduct disorder develop problems later in life including drug misuse, criminal and violent behaviour. There are more than 80,000 looked after children in the UK, with 5000 in Wales. Challenging child behaviour is the main reason for placement breakdown and has huge cost implications as challenging children cost up to 10 times more in service use than children without conduct disorder. The Incredible Years (IY) evidence-based parenting programme is an effective, low cost solution in improving child behaviour and social competence in 'conventional' families and thus has the potential to support foster carers in managing difficult behaviours. Our main aims were to establish: • The feasibility of delivery and the effectiveness of the IY parenting programme in supporting carers in managing difficult behaviour in looked after children. • Service use costs for foster carers and looked after child., Methods: This was a 12-month trial platform study with 46 foster carers in three authorities in Wales. Carers were allocated 2:1 intervention to waiting-list control. Validated measures were used to assess 'parenting' competency, carers' depression levels, child behaviour and service use. Measures were administered at baseline and 6-month follow-up. Intervention carers received the programme between baseline and follow-up., Results: Analyses showed a significant reduction in child problem behaviour and improvement in carers' depression levels for intervention families at follow-up, compared with control. Unexpectedly, there was a significant improvement in control carers' self-reported 'parenting' strategies. Special education was the greatest service cost for looked after children., Conclusions: Initial foster carer training could incorporate the IY programme to support carers in establishing positive relationships and managing difficult child behaviour. Programme participation may lead to reduced service use and improved placement stability., (© 2010 Blackwell Publishing Ltd.)

Background: The typical pattern for intervention outcome studies for conduct problems has been for effect sizes to dissipate over time with decreasing effects across subsequent follow-ups., Aims: To establish whether the short-term positive effects of a parenting programme are sustained longer term. To observe trends, and costs, in health and social service use after intervention., Method: Parents with children aged 36-59 months at risk of developing conduct disorder (n = 104) received intervention between baseline and first follow-up (6 months after baseline n = 86) in 11 Sure Start areas in North Wales. Follow-ups two (n = 82) and three (n = 79) occurred 12 and 18 months after baseline. Child problem behaviour and parenting skills were assessed via parent self-report and direct observation in the home., Results: The significant parent-reported improvements in primary measures of child behaviour, parent behaviour, parental stress and depression gained at follow-up one were maintained to follow-up three, as were improved observed child and parent behaviours. Overall, 63% of children made a minimum significant change (0.3 standard deviations) on the Eyberg Child Behavior Inventory problem scale between baseline and follow-up (using intention-to-treat data), 54% made a large change (0.8 standard deviations) and 39% made a very large change (1.5 standard deviations). Child contact with health and social services had reduced at follow-up three., Conclusions: Early parent-based intervention reduced child antisocial behaviour and benefits were maintained, with reduced reliance on health and social service provision, over time.

Objective: To investigate the cost effectiveness of a parenting programme., Design: An incremental cost effectiveness analysis alongside a pragmatic randomised controlled trial of the effectiveness of a group parenting programme delivered through Sure Start in the community., Setting: Sure Start areas in north and mid Wales., Participants: Parents of 116 children aged 36-59 months (87% of the clinical sample) at risk of developing conduct disorders defined by scoring over the clinical cut off on the Eyberg child behaviour inventory). Children were identified by health visitors and recruited by the research team., Intervention: The Webster-Stratton Incredible Years basic parenting programme or a six month waiting list control., Main Outcome Measure: Incremental cost per unit of improvement on the intensity score of the Eyberg child behaviour inventory., Results: The bootstrapped incremental cost effectiveness ratio point estimate was 73 pounds sterling (109 euros, $142) per one point improvement on the intensity score (95% confidence interval 42 pounds sterling to 140 pounds sterling ). It would cost 5486 (8190 euros, $10,666) to bring the child with the highest intensity score to below the clinical cut-off point and 1344 (2006 euros, $2618) to bring the average child in the intervention group within the non-clinical limits on the intensity score (below 127). For a ceiling ratio of 100 pounds sterling (149 euros, $194) per point increase in intensity score, there is an 83.9% chance of the intervention being cost effective. The mean cost per child attending the parenting group was 1934 pounds sterling (2887 euros, $3760) for eight children and 1289 pounds sterling (1924 euros, $2506) for 12 children, including initial costs and materials for training group leaders. When we categorised the sample into relatively mild, moderate, and severe behaviour groups based on intensity scores at baseline the intervention seemed more cost effective in those with the highest risk of developing conduct disorder., Conclusion: This parenting programme improves child behaviour as measured by the intensity score of the Eyberg child behaviour inventory at a relatively low cost and was cost effective compared with the waiting list control. This parenting programme involves modest costs and demonstrates strong clinical effect, suggesting it would represent good value for money for public spending.

Objective: To evaluate the effectiveness of a parenting programme as a preventive intervention with parents of preschool children considered to be at risk of developing conduct disorder., Design: Pragmatic randomised controlled trial using a block design with allocation by area., Setting: Eleven Sure Start areas in north and mid-Wales., Participants: 153 parents from socially disadvantaged areas, with children aged 36-59 months at risk of conduct disorder defined by scoring over the clinical cut off on the Eyberg child behaviour inventory. Participants were randomised on a 2:1 basis, 104 to intervention and 49 to remaining on the wait listing (control). Twenty (13%) were lost to follow-up six months later, 18 from the intervention group., Intervention: The Webster-Stratton Incredible Years basic parenting programme, a 12 week group based intervention., Main Outcome Measures: Problem behaviour in children and parenting skills assessed by self reports from parents and by direct observation in the home. Parents' self reported parenting competence, stress, and depression. Standardised and well validated instruments were used throughout., Results: At follow-up, most of the measures of parenting and problem behaviour in children showed significant improvement in the intervention group. The intention to treat analysis for the primary outcome measure, the Eyberg child behaviour inventory, showed a mean difference between groups of 4.4 points (95% confidence interval 2.0 to 6.9, P<0.001) on the problem scale with an effect size of 0.63, and a mean difference of 25.1 (14.9 to 35.2, P<0.001) on the intensity scale with an effect size of 0.89., Conclusion: This community based study showed the effectiveness of an evidence based parenting intervention delivered with fidelity by regular Sure Start staff. It has influenced policy within Wales and provides lessons for England where, to date, Sure Start programmes have not been effective., Trial Registration: ISRCTN46984318.
