SCL-3/7 data

A sample of 14,036 administrations was collected in the Standard Evaluation Project (1). This was a project grounded by the Stichting Klinische Psychotherapie (SKP) with 10 participating mental clinics in the Netherlands. Four subgroups were distinguished within this sample: outpatients, day care patients, inpatients and juvenile patients. Outpatients had one or more individual hours of therapy per week, fortnight or month. Day care patients had one or more days of therapy each week, and inpatients stayed overnight and were released in the weekends. All data were administered with paper and pencil. In principle, administration was at five time points: at start of the treatment, at the end of treatment, and follow-ups at six months and one year. Some participating mental clinics also had an interim administration during the treatment. Juvenile patients were younger than twenty years of age. Another sample comprised 1019 consecutive applicants to outpatient treatment facilities for addiction (substance use and impulse-control disorders) at Novadic-Kentron in Roosendaal and Bergen op Zoom in The Netherlands. This resulted in a total sample of 15,055 participants.
