Projects

The aim of the project is to identify patients at risk for pharmacological treatment resistance at an early stage and to be able to improve their treatment. For this purpose, the efficacy of early intensive pharmacological treatment strategies will be evaluated in patients with schizophrenia, those with bipolar disorders, and those with major depressive disorders who did not respond to first-line treatment. We contribute to the study by collecting digital biomarkers, i.e., a combination of digital phenotyping and electronic diaries, over a sampling period of 42 days. For this first time, we will assess voice recordings that allow for paralinguistic and voice-feature analyses. We will examine differences and transdiagnostic patterns among the three clinical groups and seek to determine whether digital biomarkers contribute to better prediction of individual  treatment response. The data then adds to multimodal machine learning-based biomarker identification with multi-omics as part of a rich collection of genetic, biological, digital, and clinical data.

Objective:

BeACTIVE focuses on one of the most serious global health problems: Physical inactivity. Mobile technologies will be used to develop a self-learning system that uses artificial intelligence to support the promotion of physical activity at the right time and in the right environment.

The Institute of Sports and Sports Science and the FZI Research Center for Information Technology are working together to address the issue of artificial intelligence and to link it to current methods of measuring everyday physical activity (e.g. acceleration measurement) and to develop new algorithms. In particular, the project focuses on one of the most serious global health problems: Physical inactivity. The World Health Organization sees digital, mobile technologies (e.g. just-in-time adaptive interventions) as the most promising approach to solve this health problem. As yet, the potential of these innovative methods is not being realized because self-learning, real-time systems based on AI are not available due to a lack of data science skills in the health sciences. However, these are essential to ensure that the mobile systems (including accelerometry and electronic diaries) and the recored multimodal data sources not only prompt people to take a break from sitting or to do more physical activity, but do so at individually favorable times in individually favorable environments. A unique database from previous research projects is available for testing, combining and training the AI algorithms.

Sedentary behavior is associated with mental and physical disorders. To better understand temporary determinants and consequences of sedentary breaks, cognitive and affect-related parameters in particular should be investigated on an intraindividual level using Ambulatory Assessment (AA) methodology. Central questions of this project aim to investigate, using a newly developed within-person encouragement design (WPED), the causal effect of sedentary breaks on the parameters of affective states and working memory in everyday life.

Bipolar disorders are severe chronic illnesses marked by recurrent episodes of depression and (hypo-)mania. Prevention is essential since these episodes are associated with marked impairment in social and occupational functioning. We conduct a randomized, multi-center, observer-blind, parallel group controlled trial with an 18-month intervention phase to investigate whether early warning signs of new depressive or (hypo-)manic episodes and individual threshold-based early interventions will prolong time to a new mood episode. In details, we continuously assess telephone usage (phone calls, text messages and internet usage), movement behavior (steps, movement patterns and activity classes) as well as location (GPS-data) across 18 months. Individual symptom thresholds are defined during 4 consecutive weeks of stabilization. Patients with randomization criteria enter the intervention phase for 18 months. This includes real-time data capturing and data-driven individual symptom-threshold-defined therapeutic interventions in addition to state-of-the-art maintenance treatment.

Progress in mobile technology in recent years enables studying processes in daily life, using digital phenotyping, smartphone technology and wearables. The focus of this project is affect, one of the most central determinants of adaptive systems. Leveraging recent developments from affective computing, we will extract sentiment and voice features of spoken language from daily life assessments as input for adaptive systems. We will partly focus on mental health populations to achieve maximum differences in experienced affect in everyday life.

In this multicenter study, we examine high- and low-frequency mood changes with ambulatory assessment (AA) in young patients suffering from bipolar disorder, borderline personality disorder, and ADHD at five different study sites. Over one year, next to e-diaries, we use digital phenotyping to gain better insight into people's behavior, such as activity or communication behavior. To analyze patterns of affective dynamics, we extend the DynAffect model, which proposes a person-specific affective homebase reflecting an organism’s main affective state, by proposing a second (or third, respectively) affective homebase during depressive (or manic) episodes. Moreover, we will examine the impact of stress, sleep, and polygenic risk scores on the parameters of the Modified DynAffect model.

The overall aim of the consortium EMPOWERYOU is to support foster and adoption families as well as children and adolescents in care to better cope with the history of early traumatic experiences and to empower them against the risk of future victimization. The subproject supported by the mental mHealth will investigate the dynamic interactions between revictimization experiences and social information processing in the everyday lives of affected children and adolescents. The methodology of ambulatory assessment via smartphones is intended to enable insights into these dynamic interactions.

Foster care and adoption services provide services to children who have been maltreated or whose parents cannot provide adequate care for them. However, it has been shown that the majority of these children have not only already experienced the devastating impact of neglect and abuse in the past but continue to be at increased risk of different types of subsequent victimization. EMPOWERYOU aims to (1) investigate factors contributing to (re-)victimization experiences in youth in care; (2) develop innovative methods to assess victimization experiences and altered social information processing; (3) co-design two tailored prevention packages using a participative approach; test the efficacy of (4) a multifactorial Internet-based prevention program for primary caregivers of children aged 8 to 13 years and of (5) an Internet-based prevention program to reduce the risk of (re-)victimization in youth in care, aged 14 to 21 years. Risk and protective factors for re-victimization will be tested in the adolescents’daily life by web-based and ecological momentary assessments. Based on these findings, two Internet-based prevention programs will be designed using consensus-based approaches integrating input from all sources of expertise, including the participants themselves, and their efficacy will be evaluated.

We are complementing two projects (A1 and A2) of this consortium with an e-diary assessment to get insight into psychosocial processes and to test the impact of the interventions in real life.

START A1: A randomized, waitlist controlled, multicentric study to evaluate the START - Intervention for adolescent refugees with posttraumatic stress disorder.

Posttraumatic stress disorder is highly prevalent in refugees, but to date, only a few have access to therapeutic support in Germany. The project evaluates a group training to stabilize traumatized adolescent refugees. We are complementing the evaluation using a one-week smartphone assessment before and three times after the intervention to assess the effects and possible consistency of the impact of the training in everyday life of the patients. Furthermore, we are interested in getting insight into the psychosocial processes, notably the reciprocal effects of stress, trauma symptoms, social conflicts, social support, discrimination, and emotions besides others.

START A2: A mentalization-based preventive intervention for childcare workers working with traumatized refugee toddlers.

The study evaluates a mentalization-based prevention program for childcare workers, focusing on the process of transition of toddlers to childcare. We are again complementing the evaluation of the program with an a-diary assessment, which will be implemented one working week before the intervention and one working week after. We are especially interested in potential differences in the mentalization of childcare workers regarding the cultural background of their interaction partner. Furthermore, we want to analyze the impact of the mentalization program regarding emotions, self-efficiency, and perceived stress of the childcare workers during interactions with parents or children, to prove the effectiveness of the training.

To investigate whether physical activity interacts with dietary patterns to modify impulsive and compulsive disorders and behaviours, we further developed the mHealth device that has been set up for the CoCA-project. Therefore, we engineer an mHealth tool by implementing more measures on impulsive and compulsive behaviours, food intake, physical activity and circadian rhythms. Furthermore, we combine subjective ratings of impulsivity with neurophsycological measures of impulsivity realized by cognitive tasks at the smartphone. The study is part of the EU-funded project “Effects of Nutrition and Lifestyle on Impulsive, Compulsive, and Externalizing behaviors” (Eat2beNICE) integrating epidemiological, genetic and experimental studies as well as clinical trials to investigate the effect of dietary patterns on mental illnesses.

As a part of the EU-funded research project Comorbid Conditions of ADHD (CoCA) we are studying the effectiveness of non-pharmacological interventions, which promise to alleviate some core symptoms of ADHD and it’s comorbidities in a sample of ADHD-diagnosed patients and healthy controls. We therefore developed the mHealthApp, enabling us to raise a multitude of physio- and psychometric data in an ambulatory setting. Participants keep a eDiary, by fulfilling repeated questionnaires on the smartphone four times a day. The diary comprises questions to check for the current mood, social context as well as the presence of positive and negative events, occurring in participants’ daily life. The activity sensor records measurement signals including 3D-accelerometry, light situation and gyroscopy, making it possible to calculate a large number of secondary parameters, such as energy expenditure, amout of steps or sleep duration. The sports- and light-therapies tested within are led by the mHealthApp through triggers, instructional videos and daily feedback.
