Social Support and Social Isolation in Psychiatric Disorders
My research has helped demonstrate the potent influence of social connection—including social support, loneliness, and social isolation—on the shape and course of major depression. This body of work has used quantitative data from longitudinal observations to demonstrate the beneficial impact of social support as well as the detrimental influence of insufficient social interactions. I have also used a qualitative approach to better understand patient perspectives in hopes of improving communication and treatments. Results have focused, in particular, on major depressive disorder and suicide risk. This work has been highlighted by national media multiple times.

Hikikomori and social withdrawal across culture

As one way to understand how social relationships impact mental health, my work has examined an extreme variant of social withdrawal called hikikomori. My studies have helped to characterize hikikomori in different international contexts, establish a definition, and develop measurement tools.  This work has been widely disseminated by national and international media, established my reputation as an international expert on hikikomori, and inspired interest amongst a new generation of researchers in the nascent field.

USe of social media for mental health outreach and engagement

Within the broader area of mental health aspects of social media use, I have conducted research focusing on the examination of social media platforms as a contemporary vehicle for communication and social connection. My work in this area tries to identify opportunities to harness the positive role of social media while minimizing potential harms, with a specific goal of promoting enhanced mental health treatment engagement. Some of my research has studied whether and how Facebook can be used to reach otherwise hard-to-reach populations such as veterans at risk for suicide. Other studies have examined tendencies toward help-seeking and exchange of social support on social media platforms.


suicide prevention in at-risk health populations

I have examined several aspects relevant to improving suicide prevention, including examining the accuracy of methods to identify individuals at risk for suicide and suicide attempts, and exploring how social support and social networks can be effectively used to mitigate risk of suicide. Thus far, I have focused on applications in two distinct, at-risk communities: military veterans and ethnic minorities. The work with veterans is directly applicable to intervention development in real-world, complex health care systems (e.g., the VA), and the work in ethnic minorities has included community-based outreach.

Promoting engagement in healthcare through nudges

I have worked to apply nudge theory and behavioral insights (inspired by behavioral economics) to the development and testing of communication campaigns with the aim of increasing patient engagement in healthcare services. Some of this work has involved harnessing the social media platform Facebook to engage Veterans in health research studies. I am currently engaged in multiple studies in this area, including one project examining content of appointment reminders and another project examining an online training to encourage engagement with healthcare for those at risk of suicide.  I have increased the impact of this area of work by focusing on interventions with potential to be highly scalable.
