Investigating the effects and mechanisms of psychotherapy
Let me introduce myself: my name is Lotte Lemmens and I’m working as an assistant professor at the department of Clinical Psychological Science at Maastricht University. My research focuses on the effects and mechanisms of psychotherapy. The treatment that I’m particularly interested in is Cognitive (behavioural) therapy (C(B)T).
In various studies, I examine clinical effects (short-term and long-term), the shape of change, processes responsible for symptom change, and (individual) variables associated with therapy success. I believe that a full understanding of why, how long and for whom psychological interventions work, is the best short- and long-term investment for improving everyday clinical practice and patient care.
Since the start of my academic career, I have examined these questions in the context of Depression (UM/PENN). I have conducted a clinical trial (RCT) to the effects and mechanisms of CT vs Interpersonal Psychotherapy (IPT) for depression (STEPd study) and am involved in a subsequent trial in which the effects of session frequency and quality of treatment on outcome are being studied (FreqMech study). Throughout the years, I extended my work to the field of eating disorders as well. I have been involved in a large study aimed at developing a self-learning CBT based E-coach (smartphone app) for weight loss and ran various experiments. Currently, I am coordinating an RCT to the effects and mechanisms of CT vs. CT + Exposure for Eating Disorders and am working on my VENI project ‘Beating the Binge’, in which I use a network approach to study the predictors of binge eating – and the role of cognitions in particular.
Besides my research activities I work as a therapist, and as a teacher within the educational system of Maastricht University (FPN/FHML). Furthermore, I am the chair of the scientific committee of the annual conference of the Dutch association for Behavioural and Cognitive Therapies (VGCt).
Specific research topics: Treatment studies; Research conducted in clinical settings; Cognitive (behavioural) therapy; Interpersonal Psychotherapy; (Cue) exposure; Treatment outcomes; Shape of change; Mediators of treatment effects; Optimal treatment selection; Sudden Gains; (Dynamic) Relations between symptoms; Depression; Eating Disorders; Binge Eating; EMA; EMI; Experiments.
I’m a course coordinator, practical coordinator, lecturer, tutor and skills trainer in various psychopathology-related courses in the bachelor and master of Mental Health Sciences (FHML) and Psychology (FPN). I am mentoring FPN bachelor students, advising PhD students (co-promotor), and have supervised dozens of students in the process of writing their bachelor’s and master’s thesis. In addition, I am a member of the FPN Educational Section and the board of admissions of the Research Master in Cognitive and Clinical Neuroscience (psychopathology track). In 2018, I won the FPN Teaching Award.
I would be happy to be an advisor for students who are interested in writing their thesis on topics related to psychotherapy for eating disorders or depression. Furthermore, master students interested in the topics of my research are more than welcome for a research internship to gain practical research experience in the context of one of my ongoing projects.
Besides my scientific activities I work as a therapist.
