ARTICLESIs Stacking Intervention Components Cost-Effective? An Analysis of the Incredible Years Program
Section snippets
METHOD
The IY program, developed by one of the present authors (C.W.S.), and evaluated by colleagues at the University of Washington's Parenting Clinic, seeks to reduce delinquency, drug abuse, and violent behaviors among children with conduct problems. Treatment focuses on the reduction of conduct problems in children; the improvement of children's social, emotional, and academic abilities; the enhancement of parental competence; the encouragement of positive parenting techniques; and the promotion
RESULTS
The data provided in Table 1 indicate that children were not yet 6 years old at study entry. The vast majority of the children were white, and consistent with the population prevalence of CD, the majority of participants were male (American Psychological Association, 2000). The average maternal age was 36.5 years, suggesting that the youth comprising the sample may not represent first-born children.
Table 3 reports the change scores across waves for each treatment category as measured by the
DISCUSSION
This article examines the differential cost-effectiveness of delivering multiple treatment components in combination versus the delivery of a single component within the context of the Incredible Years program. A sophisticated (and appropriate) cost-effectiveness methodology-cost-effectiveness acceptability curves-was applied to the data.
Cost-effectiveness acceptability curves represent an important tool for comparing competing treatments or treatment formats. The degree of certainty is a

Parent Training for Childhood Conduct Problems
2022, Comprehensive Clinical Psychology, Second EditionHelping the noncompliant child: An updated assessment of program costs and cost-effectiveness
2020, Children and Youth Services ReviewCitation Excerpt :In the United States, the average PCIT cost of therapist time was $980 per family, with a cost-effectiveness ratio of $25 per 1-point improvement in the ECBI intensity score (French, Yates, & Fowles, 2018). For IY in the United States, the costs of materials and staff time to deliver the parenting skills component of the program was estimated to cost approximately $620 per family (Foster, Olchowski, & Webster-Stratton, 2007). Cost effectiveness, however, was not assessed as part of this study.

2015, Journal of AdolescenceCitation Excerpt :The Triple P aims at reducing problem behaviour by giving support to parents and helping to establish a good child–parent relationship. Several studies indicate that the programme is most likely to be cost-effective, even though it depends on societal willingness to pay for the benefits (e.g. Foster, Olchowski, and Webster-Stratton (2007)). We chose to evaluate the OBPP because it is well known and by far the most evaluated bullying prevention programme.
