About

Bipolar disorders are severe chronic disorders, marked by recurrent episodes of depression and (hypo)mania. The disorder usually emerges in early adulthood and tends to have a highly unpredictable course. Prevention of these episodes is essential, as they are associated with marked impairment in social and occupational functioning. The investigators propose to conduct a randomized, multi-center, observer-blind, parallel group controlled trial with an 78 week (18 month) intervention phase to test the hypothesis that continuous ambulatory real-time monitoring of early warning signs for new depressive or (hypo)manic episodes by smartphone based, innovative technology (e.g. GPS, acceleration sensor), including individual threshold- based early intervention for these early warning signs, will prolong time to a new mood episode and reduce hospitalizations (intervention group). In the control group ambulatory monitoring of early warning signs for emerging depressive or (hypo)manic episodes will occur in an identical manner, but the results will not be transmitted to the treating psychiatrist. All patients in this trial, irrespective of their group assignment, will receive guideline-based, state-of-the-art maintenance treatment.

Full description

Symptomatic outpatients with bipolar disorders I/II , will be consecutively assessed for eligibility. After having signed informed consent patients will receive open, guideline-based, state-of-the-art treatment for their current symptomatology ((hypo)manic and/or depressed) for up to 16 weeks. As soon as patients meet stabilisation criteria (YMRS total score < 12 and IDS total score < 12) they will be equipped with a study smartphone, for exclusive use during the study period, to assess the parameters of interest (activity, communication pattern, sleep pattern) and define the individual symptoms' threshold during 4 consecutive weeks of stabilisation . If patients fulfil randomization criteria (4 consecutive weeks with YMRS total score < 12 and IDStotal score < 12), they will enter the observer (rater) - blind, intervention phase, which will continue for 18 months (78 weeks). At randomization patients will be assigned to either the Smartphone-Based Ambulatory Assessment group, including real-time data capture and data-driven, individual symptoms' threshold-defined therapeutic interventions (SBAA+), in addition to state-of-the-art maintenance treatment or the Smartphone-Based Ambulatory Assessment group, only including real-time data capture (SBAA), in addition to state-of-the-art maintenance treatment.

Single Blind

180 participants in 2 patient groups

SBAA+
Experimental group
Description:
Upon exceeding pre defined SBAA-threshold limits during the randomisation phase the treating physician is alerted (+) to this signal and required to contact the patient so as to assess the current mental status and collaboratively discuss the potential need for medical/psychiatric treatment with the patient.
Treatment:
Device: Smartphone-Based Ambulatory Assessment, Feedback via physician
SBAA
No Intervention group
Description:
Continuous monitoring will occur analogous to SBAA+. Exceeding the pre defined SBAA-threshold will not result in any action taken.
