Abstract

Text-message-based interventions hold great potential for intervention and are increasingly feasible, given advances in information technology. This pilot randomized controlled trial (RCT) aims to compare the efficacy of self-versus expert-authored content delivered via text-messaging for smoking cessation. Sixty-two participants aged 25-66 attended laboratory sessions pre- and post-30 days of text-messaging intervention. Participants were randomised to one of two experimental conditions - self-authorship (SA) only and SA with implementation intentions (SA+ii) - or active control. Participants composed 30-60 brief motivational cessation messages for use during their cessation attempt. SA+ii participants were further instructed to anticipate obstacles and form simple if-then plans to overcome them. Experimental groups received their self-authored texts during the intervention phase, whereas control participants received expert-authored messages. Overall, smoking decreased as measured by change in exhaled carbon monoxide (CO), F(1,59) = 4.43, p = 0.04. The SA+ii group showed slightly greater CO reduction (M = 3.63, SD = 5.39) than control (M = 0.03, SD = 5.80; t(40) = 2.08, p = 0.04). SA alone (M = 1.97, SD = 9.30) was not more e...Continue Reading

Autoimmune Diseases

Autoimmune diseases occur as a result of an attack by the immune system on the body’s own tissues resulting in damage and dysfunction. There are different types of autoimmune diseases, in which there is a complex and unknown interaction between genetics and the environment. Discover the latest research on autoimmune diseases here.
