    • Ambulatory vocal acoustics, temporal dynamics, and serious mental illness 

      Cohen, Alex S.; Fedechko, Taylor L.; Schwartz, Elana K.; Le, Thanh P.; Foltz, Peter W.; Bernstein, Jared; Cheng, Jian; Holmlund, Terje Bektesevic; Elvevåg, Brita (Journal article; Tidsskriftartikkel; Peer reviewed, 2019)
      Acoustic analysis of vocal expression offers a potentially inexpensive, unobtrusive, and highly sensitive biobehavioral measure of serious mental illness (SMI)-related issues. Despite literature documenting its use for understanding SMI, prior studies have largely ignored that vocal expression is highly dynamic within individuals over time. We employed ambulatory vocal assessment from SMI outpatients ...

    • The importance of loneliness in psychotic-like symptoms: Data from three studies 

      Le, Thanh P.; Cowan, Tovah; Schwartz, Elana K.; Elvevåg, Brita; Holmlund, Terje Bektesevic; Foltz, Peter W.; Barkus, Emma; Cohen, Alex S. (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-10-19)
      Poor social connection or loneliness is a prominent feature of schizotypy and may exacerbate psychosis risk. Previous studies have examined the inter-relationships between loneliness and psychosis risk, but critically, they have largely been conducted in non-clinical samples or exclusively used laboratory questionnaires with limited consideration of the heterogeneity within schizotypy (i.e., positive, ...

    • Predicting self-injurious thoughts in daily life using ambulatory assessment of state cognition 

      Le, Thanh P.; Moscardini, Emma; Cowan, Tovah; Elvevåg, Brita; Holmlund, Terje Bektesevic; Foltz, Peter W.; Tucker, Raymond P.; Schwartz, Elana K.; Cohen, Alex S. (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-04-12)
      Self-injurious thoughts (SITs) fluctuate considerably from moment to moment. As such, “static” and temporally stable predictors (e.g., demographic variables, prior history) are suboptimal in predicting imminent SITs. This concern is particularly true for “online” cognitive abilities, which are important for understanding SITs, but are typically measured using tests selected for temporal stability. ...

    • Psychiatric Risk Assessment from the Clinician´s Perspective: Lessons for the Future 

      Cohen, Alex S.; Fedechko, Taylor L.; Schwartz, Elana K.; Le, Thanh P.; Foltz, Peter W.; Bernstein, Jared; Cheng, Jian; Rosenfeld, Elizabeth; Elvevåg, Brita (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-06-01)
      Accurate prediction of risk-states in Serious Mental Illnesses (SMIs) is critical for reducing their massive societal burden. Risk-state assessments are notably inaccurate. Recent innovations, including widely available and inexpensive mobile technologies for ambulatory “biobehavioral” data, can reshape risk assessment. To help understand and accelerate clinician involvement, we surveyed 90 ...

    • Validating Biobehavioral Technologies for Use in Clinical Psychiatry 

      Cohen, Alex S.; Cox, Christopher R.; Tucker, Raymond P.; Mitchell, Kyle R.; Schwartz, Elana K.; Le, Thanh P.; Foltz, Peter W.; Holmlund, Terje Bektesevic; Elvevåg, Brita (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-06-11)
      The last decade has witnessed the development of sophisticated biobehavioral and genetic, ambulatory, and other measures that promise unprecedented insight into psychiatric disorders. As yet, clinical sciences have struggled with implementing these objective measures and they have yet to move beyond “proof of concept.” In part, this struggle reflects a traditional, and conceptually flawed, application ...
