Measurement quality of the Strengths and Difficulties Questionnaire for assessing psychosocial behaviour among Dutch adolescents
Jorien Vugteveen
1. The Strengths and Difficulties Questionnaire (SDQ): small is beautiful, but it comes at a price.
2. The cut off values that are widely used for interpreting SDQ scale scores in mental healthcare practice, are outdated and at most marginally useful among Dutch adolescents.
3. SDQ scales that are highly predictive of relevant outcomes, are useful for screening purposes, regardless of their estimated reliability coefficients.
4. Considering SDQ scales separately oversimplifies the complex reality of an individual’s psychosocial well-being. It is a concession that we should not accept.
5. Identifying adolescents with psychosocial problems is not the same as identifying adolescents in need of help to deal with their psychosocial problems.
6. It is not justifiable that there are occasions that SDQ data are only (or primarily) gathered for insurance and policy-making purposes. The information in the data should be put to use for the direct benefit of adolescents.
7. Validity is an ongoing process (Hubley & Zumbo, 2011), meaning that the validity evidence presented in this thesis is incomplete and possibly already partially outdated.
8. Applied science is quite beautiful and revealing. Sometimes it is about finding answers and solutions as practical and ugly as duct tape on a broken car bumper (Pendergrass, 2020).
9. I’ve been told repeatedly by senior scientists that to have a successful career in science I should work (much) more than contract hours. They were wrong. You can’t do a good job if your job is all you do (inspired by Marieke Timmerman and Annelies de Bildt).
10. The world needs science, science needs women. To close the gender gap in science we need to start truly appreciating the qualities that make women great scientists.
