A thesis presented to the Department of Psychology and the Clark Honors College of the University of Oregon in partial fulfillment of the requirements for degree of Bachelor of Arts, Spring 2014.Previous research has examined the effectiveness of text message based intervention systems and have found that tailored messages written by peers rather than distinct others are more effective (Kreuter & Holt, 200 I; Smith, Atkin, Skubisz, Nazione, & Stohl, 2009. These studies have focused on the relationship between the authorship and subsequent effectiveness ratings, rather than the written components of the text messages. The current study examines the effect of the presence of social values (SV) on the perceived effectiveness ratings of self-authored text messages aimed at aiding smoking cessation. Participants (N= 60) received text messages either written by themselves or a health organization for a period of three weeks, six times a day, responding to each message with an effectiveness rating ( 1-5). Results reveal that social values are a significant factor in the effectiveness of text-messages as an intervention system, and that a presence of social support (SS) magnifies this relationship.en-USAll Rights Reserved.Social valuesSocial supportSmoking cessationSelf-authoredText messagesModeratingThesis / Dissertation
