OBJECTIVES The primary aim of the study was to identify specific strengths and challenges of facilitating online cancer support groups relative to face-to-face groups through the use of deductive qualitative analysis. A secondary aim was to quantitatively validate the identified strengths and challenges. METHODS To better understand how facilitators'(More)
OBJECTIVE Little is known about how positive group interactions develop in online support groups. Previous research suggests that message content, self-disclosure, and emotional expression may be central to this process. The purpose of this study was to identify linguistic and qualitative characteristics of participants' messages that predict how other(More)

The purpose of the present study was to develop and evaluate the effects of linguistically-tailored feedback on an Internet-based expressive writing intervention. Two hundred eighty-one(More)
Web and mobile (mHealth) interventions have promise for improving health outcomes, but engagement and attrition may be reducing effect sizes. Because social networks can improve engagement, which is a key mechanism of action, understanding the structure and potential impact of social networks could be key to improving mHealth effects.

OBJECTIVE We tested a dual-process model based on behavioral and emotional regulation constructs, which posits that good self-control and poor regulation make independent contributions and have different types of pathways to outcomes. The utility of the model for predicting substance use was tested in two diverse populations of younger adolescents. METHOD(More)
