Biography
Femke L. Truijens is Assistant Professor Clinical Psychology, conducting interdisciplinary research on the borderline of clinical psychology, methodology and philosophy of science.
Dr. Truijens focuses on the most basic but often overlooked questions of clinical research: What counts as evidence? Are data automatically valid when collected by validated measures? How do people actually quantify their experienced complaints when they score symptom measures? And how are therapeutic changes captured by aggregated pre-post differences? By taking a qualitative stance to quantitative data collection, dr. Truijens explores clinical validity in clinical research. In her PhD at Ghent University, Belgium, she analysed empirical data from the Ghent Psychotherapy Study (a mixed-method RCT on differential efficacy of cognitive-behavioral and psychodynamic treatment for depression) to study validity of data and evidence in randomized controlled therapy research. At ESSB, she conducts a stakeholder study on how validity is understood and secured in Routine Outcome Measurement in the Dutch GGZ. She develops and teaches Severe Mental Illness in Urban Contexts, which explores pluralist perspectives on diagnostics and the recovery paradigm. Dr. Truijens initiated and chairs the Qualitative Research Collective GGZ in The Netherlands, and initiated and chairs the international SPR interest group Evidence for Guidelines. In her private practice, dr. Truijens provides psychotherapy for gifted adults and adolescents with mental health issues.
