Ybarra ML, Jiang Y, Free C, Abroms LC, Whittaker R. Participant-level meta-analysis of mobile phone-based interventions for smoking cessation across different countries. Prev Med. 2016;89:90-97. doi: 10.1016/j.ypmed.2016.05.002. Abstract: With meta-analysis, participant-level data from five text messaging-based smoking cessation intervention studies were pooled to investigate cessation patterns across studies and participants. Individual participant data (N = 8315) collected in New Zealand (2001–2003; n = 1705), U.K. (2008–2009; n = 5792), U.S. (2012; n = 503; n = 164) and Turkey (2012; n = 151) were collectively analyzed in 2014. The primary outcome was self-reported 7-day continuous abstinence at 4 weeks post-quit day. Secondary outcomes were: (1) self-reported 7-day continuous … [Read more...]
Examining the influence of a text message-based sleep and physical activity intervention among young adult smokers in the United States
Filion J, Darlington G, Chaput J, Ybarra M, Haines J. Examining the influence of a text message-based sleep and physical activity intervention among young adult smokers in the United States. BMC Public Health. 2015;15(1): 671. doi: 10.1186/s12889-015-2045-2 Abstract: BACKGROUND: Sleep and physical activity are two health behaviors associated with improved smoking cessation outcomes. Text message-based interventions have previously been used to promote physical activity and smoking cessation; however, this type of intervention has not targeted sleep habits. This study examined the effectiveness of a text message-based active control intervention in improving sleep and physical activity habits among a U.S. national sample of young adult smokers participating in a smoking cessation … [Read more...]

Meta-analysis of mobile phone-based interventions for smoking cessation trials in different countries
Jiang Y, Huang Y, Ybarra ML, Abroms L, Free C, Whittaker. (2014). Meta-analysis of mobile phone-based interventions for smoking cessation trials in different countries. Poster presented at 35th Annual Conference of the International Society for Clinical Biostatistics, Vienna, Austria Tobacco use contributes to 12% of all deaths among adults ages 30 years and older worldwide. Smoking cessation programs delivered via mobile phone text messaging are available in several different countries to help people quit smoking. Although results suggest increases in self-reported quitting, at least in short-term, little is know about how this differs for different cultures. … [Read more...]
Process evaluation of a mHealth program: Lessons learned from Stop My Smoking USA, a text messaging-based smoking cessation program for young adults
Ybarra ML, Holtrop JS, Prescott TL, & Strong D. Process evaluation of a mHealth program: Lessons learned from Stop My Smoking USA, a text messaging-based smoking cessation program for young adults. Patient Educ Couns. 2014;97(2):239-243. doi: 10.1016/j.pec.2014.07.009 Abstract: OBJECTIVE: Report lessons learned in an RCT of Stop My Smoking (SMS) USA, a mHealth smoking cessation program for young adult smokers. METHODS: 164 18–24-year-olds were recruited nationally, online in 2011. Program evaluation data were provided at 12-week post-Quit Day. RESULTS: (1) Inviting participants to complete a brief text messaging survey and then asking them to complete a longer online survey resulted in the highest response rate (89%). (2) The positive tone of program messages was the most … [Read more...]
Steps in tailoring a text messaging-based smoking cessation program for young adults
Ybarra ML, Prescott TL, Holtrop JS. Steps in tailoring a text messaging-based smoking cessation program for young adults. J Health Commun. 2014;19(12):1393-1407. doi: 10.1080/10810730.2014.901441 Abstract: Steps to develop or refine text messaging-based interventions are largely missing from the literature. Here, the authors describe steps in refining Stop My Smoking USA, a text messaging-based smoking cessation program for smokers 18-25 years old. Research activities included the following: needs assessment focus groups (n = 35); a content advisory team to affirm message acceptability (n = 10); and two beta tests to confirm technological feasibility (n = 12 and 28, respectively). Various recruitment strategies were tested to identify the optimal methods to reach young adult smokers … [Read more...]
Feasibility and acceptability of a text messaging-based smoking cessation program in Ankara, Turkey
Ybarra ML, Holtrop JS, Bağci Bosi AT, Bilir N, Korchmaros JD, Emri S. Feasibility and acceptability of a text messaging-based smoking cessation program in Ankara, Turkey. J Health Commun. 2013;18(8):960-973. doi: 10.1080/10810730.2012.757399 Abstract: Data from high-income countries suggest that cell phone-based smoking cessation programs have the potential to affect cessation rates. There is a paucity of research, however, about the feasibility of cell phone-based smoking cessation programs in lower income countries that have higher smoking prevalence rates. A one-arm feasibility and acceptability pilot study of SMS Turkey, a text messaging-based smoking cessation program, was conducted in Ankara, the capital of Turkey. The authors recruited 75 daily smokers who were seriously … [Read more...]
Pilot RCT results of Stop My Smoking USA: a text messaging-based smoking cessation program for young adults
Ybarra ML, Holtrop JS, Prescott TL, Rahbar MH, Strong D. Pilot RCT results of Stop My Smoking USA: a text messaging-based smoking cessation program for young adults. Nicotine Tob Res. 2014;15(8): 1388-1399. doi: 10.1093/ntr/nts339 Abstract: INTRODUCTION: To address the lack of smoking cessation programs available to young adults, Stop My Smoking (SMS) USA, a text messaging-based smoking cessation program, was developed and pilot tested. METHODS: This was a two-arm randomized controlled trial with adaptive randomization (arms were balanced by sex and smoking level [heavy vs. light]), conducted nationally in the United States. One hundred sixty-four 18- to 25-year-old daily smokers who were seriously thinking about quitting in the next 30 days were randomized to either (a) the 6-week … [Read more...]

Design considerations in developing a text messaging program aimed at smoking cessation is among adult smokers in Ankara, Turkey
Ybarra ML, Holtrop JS, Bağci Bosi AT, Emri S. Design considerations in developing a text messaging program aimed at smoking cessation is among adult smokers in Ankara, Turkey. J Med Internet Res. 2012;14(4):e103. doi: 10.2196/jmir.2061 Abstract: BACKGROUND: Cell phone text messaging is gaining increasing recognition as an important tool that can be harnessed for prevention and intervention programs across a wide variety of health research applications. Despite the growing body of literature reporting positive outcomes, very little is available about the design decisions that scaffold the development of text messaging-based health interventions. What seems to be missing is documentation of the thought process of investigators in the initial stages of protocol and content development. … [Read more...]
