Instability of suicidal ideation in patients hospitalized for depression: An exploratory study using smartphone ecological momentary assessment

This study used ecological momentary assessment (EMA) to explore the correlates of suicidal ideation (SI) instability in patients hospitalized for depression and SI. Thirty-nine adult inpatients were given smartphones with visual analogue scales to rate current depressed mood, anger/irritability, feeling socially connected, and SI three times a day throughout hospitalization. Affective Lability Scales (ALS) were […]

Associations between problematic smartphone use, unhealthy behaviors, and mental health status in Korean adolescents: Based on data from the 13th Korea Youth Risk Behavior Survey (2017)

Objective: We aimed to assess the associations between problematic smartphone use, unhealthy behaviors, and mental health status among adolescents. Methods: The data for this cross-sectional study were obtained from the 13th Korea Youth Risk Behavior Survey (2017). From among the 62,276 adolescents who participated in this nationwide web-based survey, 54,603 (87.7%) who used smartphones were […]

Consensus statement on ethical & safety practices for conducting digital monitoring studies with people at risk of suicide and related behaviors

Objective Digital monitoring technologies (e.g., smartphones and wearable devices) provide unprecedented opportunities to study potentially harmful behaviors such as suicide, violence, and alcohol/substance use in real‐time. The use of these new technologies has the potential to significantly advance the understanding, prediction, and prevention of these behaviors. However, such technologies also introduce myriad ethical and safety […]

Feasibility and correlations of smartphone meta-data toward dynamic understanding of depression and suicide risk in schizophrenia

Objectives We investigate whether meta‐data, specifically duration of responses to smartphone‐delivered surveys, is correlated to elevated scores on the depression assessment PHQ‐9 as well as the specific item around self‐harm (item 9). Methods In this observational study, we recruited 92 smartphone‐owning adults (≥ 18) with schizophrenia (45) and healthy controls (43). We installed an open‐source smartphone […]

Increases in depression, self-harm, and suicide among U.S. adolescents after 2012 and links to technology use: Possible mechanisms

Objective: Increases in depression among adolescents have been concurrent with increases in digital media use. In this article, recent trends in mental health among U.S. adolescents and young adults are discussed and theories about their possible connection with concurrent increases in digital media use are presented. Methods: Large studies of trends in mental health in […]

Testing out suicide risk prediction algorithms using phone measurements with patients in acute mental health settings: A feasibility study

Background: Digital phenotyping and machine learning are nowadays being used to augment or even replace traditional analytic procedures in many domains, including health care. Given the heavy reliance on smartphones and mobile devices around the world, this readily available source of data is an important and highly underutilized source that has the potential to improve […]

Evaluating the feasibility and effectiveness of an Australian safety planning smartphone application: A pilot study within a tertiary mental health service

Objective The purpose of this study was to examine the feasibility and effectiveness of a suicide prevention smartphone application. Method Thirty‐six non‐Aboriginal Australians aged between 16 and 42 years (67% female) were recruited from a tertiary mental health service where they were receiving treatment for suicide risk. Participants were asked to use the BeyondNow safety planning […]

Problematic smartphone use associated with greater alcohol consumption, mental health issues, poorer academic performance, and impulsivity

Background This study sought to examine the occurrence of the problematic use of smartphones in a university sample and associated physical and mental health correlates, including potential relationships with risky sexual practices. Methods A 156-item anonymous online survey was distributed via e-mail to a sample of 9,449 university students. In addition to problematic smartphone usage, […]

The dynamics of social support among suicide attempters: A smartphone-based daily diary study

Decades of research suggest that social support is an important factor in predicting suicide risk and resilience. However, no studies have examined dynamic fluctuations in day-by-day levels of perceived social support. We examined such fluctuations over 28 days among a sample of 53 adults who attempted suicide in the past year (992 total observations). Variability […]
