Since October 2023, I am working as an associate researcher at the Chair of Clinical Child and Adolescent Psychology and Psychotherapy. As a licensed cognitive behavioral psychotherapist, I have extensive experience in working with patients with severe mental illness. In particular, I have extensive experience in working with patients with psychotic disorders, treating delusions, hallucinations, and negative symptoms.

My research is rooted in clinical psychology, yet encompasses both etiological research on causal and maintaining factors of psychotic and other mental disorders as well as research on the active ingredients of psychotherapy. My methodological approach is longitudinal research, including therapy process assessment (Lincoln, Jung, Wiesjahn & Schlier, 2016; Schlier et al., 2020), real-time assessment of behavior and symptoms in everyday life (i.e., ambulatory assessment or ecological momentary assessment; Hennig, Schlier & Lincoln, 2020; Schlier, Krkovic, Clamor & Lincoln, 2019) and methods automated prediction (Strakeljahn, Lincoln & Schlier, submitted) and eHealth-interventions. The main aim of my research is to understand, which mechanisms trigger, intensify, and maintain symptoms such as hallucinations or delusions in everyday life. Furthermore, I explore which protective and risk factors are putative targets for interventions. Due to the relative novelty of the ambulatory assessment approach, I am additionally always keen on developing, optimizing, and validating questionnaires and other assessment paradigms for use in ambulatory assessment (Schlier, Moritz & Lincoln, 2016; Schlier, Hennig & Lincoln, 2017).

Finally, I am continuously interested in the topic of (lay) beliefs about mental health and mental disorders. In this field, my aim is to explore how beliefs and stereotypes about mental disorders are associated with people’s behavior. This includes the question what beliefs lead to empowering attitude towards mental illness free of discrimination – both in everyday-life of/by the general population (Schlier, Scheunemann & Lincoln, 2016) and within the health care system (Schlier, Kubera & Lincoln, 2020; Schlier & Lincoln, 2016).

At the Chair of Clinical Child and Adolescent Psychology and Psychotherapy, i am working on elucidating the process, by which certain triggers and risk factors contribute to the onset of psychopathological symptoms. Starting point for this research are theory-based risk factors that have mostly been explored by retrospective assessment, e.g., experiences of discrimination in adolescence as a risk factor for paranoia (Kingston, Schlier et al., 2023). Using ambulatory assessment (and a range of supplementary methods), I aim to elucidate how these risk factors lead to the initial onset of symptoms or their predecessors in everyday life. With this focus, I also continue my efforts to further develop and validate assessment methods, now also including the optimization of diagnostic instruments for use with children and adolescents (Schlier, Ellett, Thompson, Gaudiano, Krkovic & Kingston, submitted).
