Research evaluation and norms

We have conducted a series of pilots and research studies to evaluate BERRI and see how it works in practise, and we continue to collect and analyse data to make the BERRI system as helpful as it can be. Some example pilot studies include:

  • Collecting data about the first 125 children in residential care to use the system showed that they made an average improvement of 14% in the first six months
  • An initial factor analysis showed that the five areas that BERRI covers are supported by the data, and are statistically defined as fairly independent factors with certain items being critical for each. We are now looking at whether the Relationships factor can most meaningfully be interpreted as covering two subtypes of difficulties - deficits in social skills, and indicators of attachment difficulties - and whether the statistics suggest we should comment about each area separately in the reports.
  • Relationship with SDQ scores
  • Test-retest and inter-rater reliability study under way
  • Convergent and divergent validity with other measures under way
  • Collection of norms by placement type under way
  • Study of BERRI, ADHD measures and Adverse Childhood Experiences has been undertaken with 140 children, to explore how the increased fight-flight response from being exposed to trauma and/or chaotic care affects children's behaviour
