Dr. Sheeran is a social and health psychologist and conduct research on health behavior change. There are four strands to his work:

1.     A key focus has been the intention-behavior ‘gap’. Dr. Sheeran and colleagues have shown that people successfully translate (even strong) intentions into action only about 50% of the time (e.g., Orbell & Sheeran, 1998; Sheeran, 2002).  The research also pinpointed several factors that determine the consistency between intentions and behaviour (e.g., Abraham & Sheeran, 2003).

2.     A concomitant line of research uses if-then plans or implementation intentions to reduce the intention-behavior ‘gap’ and increase performance of important health behaviors. A series of RCTs has shown that forming if-then plans reduced pregnancy rates among teenagers (by 42% over two years; Martin, Sheeran et al., 2011), enhanced medication adherence among patients with epilepsy (Brown, Sheeran, & Reuber, 2009), and improved attendance for cervical cancer screening (Sheeran & Orbell, 2000), inter alia.

3.     A third line of research is concerned with providing critical tests of health behavior theories. This work uses meta-analysis to assess how much change in health-related intentions and behavior accrues from interventions that change the key predictors specified by the theories, namely, risk perceptions, fear/worry, perceptions of severity, attitudes, social norms, and self-efficacy (e.g., Sheeran, Harris, & Epton, 2013).

4.     Recent work has begun to examine nonconscious routes to action and the self-regulation of implicit influence (Gollwitzer, Sheeran et al., 2011; Rivis & Sheeran, 2013; Sheeran, Gollwitzer, & Bargh, 2013).
