How To Improve Youth Care?
• Implement evidence-based treatments?
• Focus on the common factors?
In this session:1. Is the Lambert scheme valid? 2. Implement specific evidence-based
programs?

Is The Lambert Scheme Valid? (1)1. Not based on quantative, statistical analyis,
but on impression of the literature
2. Outdated: published in 1992, based on Lambert, Shapiro & Bergin (1986)
3. Review based on data from adult psychotherapy (not youth care)
4. Studies show different definitions and results

Confusion (1): The Fuzzy Concept Of ‘Common Factors’
• Fitting the treatment with the motivational stage
• Fitting the treatment with the type and severity of the problem
• Structuring the treatment
• Working with treatment integrity
• Supporting the practitioner (e.g. with good supervision)
• Monitoring the treatment, providing feedback on results
• The quality of therapist-client relationship (‘Alliance’)
Confusing: Some call this placebo (e.g. Stevens et al., 2000), others focus on relationship factor only (e.g. Thomas, 2006)
![Page 8: Common And Specific Ingredients Of Youth Care](https://reader035.vdocuments.site/reader035/viewer/2022062520/5681598c550346895dc6d3fb/html5/thumbnails/8.jpg)

Confusion (2): Common Factors And Specific Techniques Are Very Different Entities (Or Not)
Common factors and specific techniques are mentioned separately in Lambert’s scheme. But:
Using specific techniques may contribute to• Quality of the relation (e.g. Stams e.a. 2005)
• The structuring of the treatment (e.g. Wampold, 2001)
Specific techniques are vehickels for bringing
common factors into practice (Sprenkle & Blow, 2006; Carr, 2009)

Do Specific Techniques Have A Unique Contribution?
Yes
1. Meta analyses show: a. In general, specific treatments do explain a (small) part of the
variance in outcome (Carr, 2009; Hoagwood, 2005; Asay & Lambert, 1999; Karver e.a., 2006).
b. In case of severe problems, specific treatments may be more important than common factors (Stevens et al, 2000)
2. Better implementation leads to better outcome (o.a. Aos, 2002;
Lowenkamp, 2004; Goggin & Gendreau 2006; Barnoski e.a., 2004).

3. Specific treatments not only specify the do’s, but also the don’ts, to eliminate negative influences on the total outcome.

You are managing director of a youth care provider. How do you decide to improve your services?
What is your conclusion?
By investing mainly in common factors
(specific treatments are not that important)
By implementing specific treatments
(essential in improving youth
care)
