Incredible Years® – School Age Basic Program
The Incredible Years - School Age Basic program (“IY-School Age”) can be offered as a group-based prevention or treatment program designed for parents of children (6 to 12 years). The program typically targets higher risk populations and parents of children diagnosed with problems such as oppositional defiant disorder and attention deficit hyperactivity disorder (ADHD). IY-School Age aims to strengthen parent-child interactions and attachment and reduce harsh discipline. It also aims to foster parents’ abilities to promote children’s social, emotional, and academic development and reduce behavior problems. IY-School Age focuses on 3 developmentally appropriate topics during the sessions: (1) promoting positive behavior, (2) reducing inappropriate behaviors, and (3) supporting children’s education.
During each group session, parents watch 8 to 10 situational video vignettes. They engage in discussions facilitated by the group leaders and problem solve about best parenting practices. Parents are encouraged to complete activities at home to apply the skills they learned with the group.
IY-School Age is rated as a promising practice because at least one study achieved a rating of moderate or high on study design and execution and demonstrated a favorable effect on a target outcome.

Note: For the effect sizes and implied percentile effects reported in the table, a positive number favors the intervention group and a negative number favors the comparison group. Effect sizes and implied percentile effects were calculated by the Prevention Services Clearinghouse as described in the Handbook of Standards and Procedures, Version 1.0, Section 5.10.4 and may not align with effect sizes reported in individual publications. The Prevention Services Clearinghouse uses information reported in study documents and, when necessary, information provided by authors in response to author queries to assign study ratings and calculate effect sizes and statistical significance (see Section 7.3.2 in the Handbook of Standards and Procedures, Version 1.0). As a result, the effect sizes and statistical significance reported in the table may not align with the estimates as they are reported in study documents. Effect sizes for some outcomes were not able to be calculated by the Prevention Services Clearinghouse.
Only publications with eligible contrasts that met design and execution standards are included in the individual study findings table.
Full citations for the studies shown in the table are available in the "Studies Reviewed" section.
The participant characteristics display is an initial version. We encourage those interested in providing feedback to send suggestions to preventionservices@abtglobal.com.
The table below displays locations, the year, and participant demographics for studies that received moderate or high ratings on design and execution and that reported the information. Participant characteristics for studies with more than one intervention versus comparison group pair that received moderate or high ratings are shown separately in the table. Please note, the information presented here uses terminology directly from the study documents, when available. Studies that received moderate or high ratings on design and execution that did not include relevant participant demographic information would not be represented in this table.
