Official title

Smartphone-based Digital Phenotyping to Detect High-risk Affect States in Body Dysmorphic Disorder (BDD)

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

Body dysmorphic disorder (BDD) is associated with high risk for suicide attempts (22-28%) and substance use disorders (49%), underscoring the importance of accurate, real-time risk detection in BDD. This study aims to use smartphone-based digital phenotyping to develop and validate unobtrusive, time-sensitive, and ecologically valid measures of key risk factors for suicide and substance misuse in BDD: negative affect states. As next steps, this research can be extended to detect risk transdiagnostically, with the goal of enabling just-in-time interventions to target suicide and substance misuse across psychiatric illnesses.
