GPS-triggered e-diaries, neuroimaging and genetics to unravel urbanicity risks for schizophrenia

Recent evidence suggests that the heightened prevalence of mental disorders in cities is caused by altered neural stress processing. To uncover the specific environmental sources of urban stress, we use innovative GPS-triggered e-diaries. In detail, GPS-triggered e-diaries continuously monitor participants’ locations. Changes are traced in real time on environmental components maps, covering traffic noise, population density etc., and trigger e-diary queries for affect and stress-reactivity. Methodologically, GPS-triggered e-diaries maximize the within-subject variance in real-time. The study is part of an ongoing longitudinal study (PEZ: Psychiatric-epidemiological center) combining GPS-triggered e-diaries with fMRI and biomarkers. PEZ is headed by Prof. Meyer-Lindenberg (CIMH Mannheim, Germany) and supported by the Ministry of Science, Research and the Arts of the State of Baden-Württemberg.

Activity-triggered e-diaries to investigate the mood-brightening effect of physical activity in patients with Depression or Anorexia

Although empirical studies evidence that structured exercise reduces depressive symptomatology, the underlying mechanisms are poorly understood. We use activity-triggered e-diaries pre and post a ten-week running program to investigate the within-subject dynamics between physical activity and mood in depressed students. In detail, physical activity is assessed and preprocessed on an accelerometer worn on the hip. Via Bluetooth low energy data are transmitted to a smartphone, triggering e-diary assessments if specified thresholds of activity or inactivity are surpassed. Methodologically, activity-triggered e-diaries maximize the within-subject variance in real-time. The study is run in cooperation with the Psychotherapeutic Counselling Centre, Karlsruhe. This methodological approach is also applied to investigate the relation between physical activity and mood in patients suffering from anorexia nervosa, a collaborative project headed by Prof. Zeeck (Medical Center at the University of Freiburg; funded by the Swiss Anorexia Nervosa Foundation).

Long-term tracking of communication and behaviour to predict new episodes in bipolar disorder

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.

High-frequency monitoring of affective dynamics to characterize borderline personality disorder and to predict its treatment outcome

Psychopathology is not simply experiencing weird symptoms or more negative than positive affect. Such a static view would ignore the moment-to-moment ebb and flow of symptoms, which characterizes the disorders. In a current DFG funded study “Developing mixed-latent-state-trait-models to analyse the temporal characteristics of affect and self-esteem in borderline personality disorder” we do hypothesize that the dynamical covariation of affect and self-esteem is specific for BPD. As current statistical models are limited for this kind of analyses, we will expand ordinary mixed-latent-state-trait-models to multigroup-multitrait-mixed-autoregressive-latent-state-trait-growth-curve-models. This project is run in cooperation with Prof Michael Eid (FU Berlin) and Prof. Dr. Martin Bohus (Central Institute of Mental Health, Mannheim).

Ambulatory Assessment Interventions: Reducing stress and procrastination with a smartphone app

Psychologie_StressSriAS.jpg

The primary aim of every psychological intervention is to induce some kind of change in the behaviour of the participants. To bring about substantial behavioural change, principles and strategies taught to the participants have to be transferred to their every-day-life. Ambulatory Assessment techniques help to meet that challenge by prompting individuals to apply their skills, when and where they are needed, fostering engagement and adherence, while reducing the required frequency of face-to-face sessions. Therefore, we implemented two IT-based interventions using mobile devices (smartphones). Both of these Ambulatory Assessment Interventions facilitate self-monitoring processes using real-time suggestions and feedback. The first intervention is designed to (1) examine the time-dependent change-processes underlying the emergence of procrastination and (2) to reduce academic procrastination by strengthening students everyday self-regulation (funding: BMBF).

The second intervention is integrated in a stress prevention and -management program, where e-diaries are used to support students in critical situations (funding: Techniker Krankenkasse).

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. For further information please have a look at the project’s website: http://newbrainnutrition.com.

Um zu testen, ob körperliche Aktivität mit Ernährungsmustern interagiert und impulsive oder zwanghafte Verhaltensweisen hierdurch modifiziert werden können, entwickeln wir unsere mHealth-App weiter, die bereits im CoCA-Projekt implementiert wurde. Das mobile Messinstrument erfasst Nahrungszufuhr, körperliche Aktivität, den zirkadianen Rhythmus sowie impulsives und zwanghaftes Verhalten. Impulsivität wird hierbei sowohl über subjektive Ratings, als auch über neuropsychologische Messungen mittles kognitiver Tests am Smartphone realisiert. Die Studie ist Teil des EU-finanzierten Projekts “Effects of Nutrition and Lifestyle on Impulsive, Compulsive, and Externalizing behaviors” (Eat2beNICE), das epidemiologische, genetische und psychologische Experimentalstudien vereint, um die Effekte von Ernährungsverhalten auf psychische Erkrankung zu erforschen.

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.

Als Teil des EU-finanzierten Forschungsprojekts Comorbid Conditions of ADHD (CoCA) untersuchen wir die Wirksamkeit non-pharmakologischer Interventionen zur Verbesserung der Kernsymptomatik sowie komorbider Störungsbilder bei ADHS-diagnostizierten Patient*innen und gesunden Kontrollen. Mittels der hierfür entwickelten mHealthApp und tragbaren Bewegungssensoren erheben wir eine Vielzahl physio- und psychometrischer Variablen im ambulanten Setting. Die Versuchspersonen führen smartphone-gestützte elektronische Tagebücher, die u.a. die momentane Stimmung und das Erleben emotionaler Ereignisse erfassen. Der Sensor verarbeitet Messsignale zur Lagebestimmung, 3D-Beschleunigung oder Lichtsituation, aus denen sich ein großes Spektrum sekundärer Parameter errechnen lässt (vgl. Energieumsatz, Schrittzahl, Schlafdauer). Die erprobten Sport- und Lichttherapien werden durch Erinnerungstrigger, Instruktionsvideos und tägliches Feedback ebenfalls mithilfe der mHealthApp angeleitet.
