Research summary
This is a secondary analysis of data already obtained in the Self-Harm Intervention Family Therapy (SHIFT) trial conducted at the University of Leeds. Additionally, it is a replication study testing the effectiveness of the Strength and Difficulties Added Value Score (SDQ AVS) as an outcome measure for child and adolescent services. The SDQ AVS uses a large epidemiological study of high risk pathologies to predict follow-up parental SDQ scores for the evaluation of routine outcomes. Previously, the algorithm has been tested on two randomised controlled trials. These both showed promising results, however, both trials used similar patient age groups (pre-school/reception children who were predominantly male) and the same interventions (The Incredible Years Parenting Course). Thus, testing the developed algorithm on the results from the SHIFT trial of family therapy for young people who self-harm offers further evaluation of the algorithm with a different patient population and intervention. The SHIFT randomised controlled trial compared Family Therapy (FT) with Treatment as Usual (TAU) for adolescents aged 11-17.
The current study would take some variables from the SHIFT dataset (age, gender, SDQ scores at baseline and follow up, trial arm and key socioeconomic characteristics) in order to calculate the SDQ AVS and test it against the findings reported in the trial. At the same time we will also calculate simple changes scores (which is how most routine outcome measures are compared) and test whether these are significantly different to the findings observed in the trial.
As the SDQ AVS was calculated from data gathered between 4 and 8 months after baseline, and the data in the trial were gathered at 12 months, we will use data from the British Child and Adolescent Mental Health Survey 2004 12 month follow up to develop and test a longer term follow up version of the SDQ AVS.
