Introduction
I am a research associate at the Institute for Medical Psychology and Medical Sociology, University of Freiburg. My main research interests are digital interventions to reduce suicidal ideation and behaviors. My work is dedicated to the question how digital treatments for suicide prevention can be improved and personalized. To gain new insights into participant-level effects of existing interventions, I apply the method of individual participant data (IPD) meta-analysis.

Passive sensing data from smartphones and wearables may help improve the prediction of suicidal thoughts and behaviors (STB). In this systematic review, we explored the feasibility and predictive validity of passive sensing for STB. On June 24, 2024, we systematically searched Medline, Embase, Web of Science, PubMed, and PsycINFO. Studies were elig...

Background: While the efficacy of digital interventions for the treatment of depression is well established, comprehensive knowledge on how therapeutic changes come about is still limited. This systematic review aimed to provide an overview of research on change mechanisms in digital interventions for depression and meta-analytically evaluate indi...

Predicting suicidal thoughts and behaviors (STB) remains challenging. The use of passive sensing data gathered through smartphones and wearables may contribute to overcoming current limitations in STB prediction. In this systematic review, we explored the feasibility and predictive validity of passive sensing for STB. On October 18, 2022, we system...

Background: Digital formats have the potential to enhance accessibility to care for individuals with suicidal ideation. However, digital self-help interventions have faced limitations, including small effect sizes in reducing suicidal ideation, low adherence, and safety concerns. Objective: Therefore, we aimed to develop a remote blended cognitive...

Introduction: New digital treatment formats may reduce barriers to treatment for individuals with suicidal ideation. This study aimed to investigate the feasibility of a remote blended care programme for this population, defined as acceptability, demand, practicality, adaptation, indications of efficacy and safety. Methods: We conducted a mixed-...

Background Suicide is a global public health problem. Digital interventions are considered a low-threshold treatment option for people with suicidal ideation or behaviors. Internet-based cognitive behavioral therapy (iCBT) targeting suicidal ideation has demonstrated effectiveness in reducing suicidal ideation. However, suicidal ideation often is r...

Introduction Digital cognitive behavioral therapy (i-CBT) interventions for the treatment of depression have been extensively studied and shown to be effective in the reduction of depressive symptoms. However, little is known about their effects on suicidal thoughts and behaviors (STB). Information on the impact of digital interventions on STB are...

Question: Digital interventions based on cognitive-behavioural therapy (iCBT) is associated with reductions in suicidal ideation. However, fine-grained analyses of effects and potential effect-moderating variables are missing. This study aimed to investigate the effectiveness of iCBT on suicidal ideation, effect moderators, effects on suicide atte...

Introduction The efficacy and effectiveness of digital interventions for depression are both well-established. However, precise effect size estimates for mediators transmitting the effects of digital interventions are not available; and integrative insights on the specific mechanisms of change in internet- and mobile-based interventions (IMIs)—as r...

BACKGROUND Suicide is a severe public health problem, resulting in a high number of attempts and deaths each year. Early detection of suicidal thoughts and behaviors (STB) is key to prevent attempts. Passive sensing of digital and behavioral markers is discussed to enhance detection and prediction of STB. OBJECTIVE The aim of this systematic revie...

People with suicidal ideation and non-suicidal self-injury (NSSI) behavior face numerous barriers to help-seeking, which worsened during the COVID-19 pandemic. Mobile health applications (MHA) are discussed as one solution to improve healthcare. However, the commercial app markets are growing unregulated and rapidly, leading to an inscrutable marke...

Internet-and mobile-based cognitive behavioral therapy (iCBT) might reduce suicidal ideation. However, recent meta-analyses found small effect sizes, and it remains unclear whether specific subgroups of participants experience beneficial or harmful effects. This is the study protocol for an individual participant meta-analysis (IPD-MA) aiming to de...

Importance Suicidal ideation is a widespread phenomenon. However, many individuals at risk for suicide do not seek treatment, which might be addressed by providing low-threshold, internet-based self-help interventions. Objective To investigate whether internet-based self-help interventions directly targeting suicidal ideation or behavior are assoc...

Background: Suicidal ideation is a highly prevalent condition. There are several barriers for individuals to seek treatment that may be addressed by providing internet-based self-help interventions (ISIs). Current evidence suggests that ISIs for mental disorders may only be effective in reducing suicidal ideation if they specifically target suicida...

BACKGROUND Suicidal ideation is a highly prevalent condition. Several barriers lead to a gap in healthcare provision, which might be addressed by providing internet-based self-help interventions (ISIs). Current evidence suggests that ISIs for mental disorders might only be effective in reducing suicidal ideation if they specifically target suicidal...
