Ybarra M, Bağci Bosi AT, Korchmaros J, Emri S. A text messaging-based smoking cessation program for adult smokers: randomized controlled trial. J Med Internet Res 2012; 14:e172. [PMID: 23271159 PMCID: PMC3799568 DOI: 10.2196/jmir.2231] [Citation(s) in RCA: 42] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/28/2012] [Revised: 10/05/2012] [Accepted: 10/16/2012] [Indexed: 12/02/2022] Open
Abstract
BACKGROUND Despite promising data in Western countries, there is a dearth of research into the efficacy of text messaging-based smoking cessation programs in other settings, including the Middle East, where smoking prevalence rates are higher. OBJECTIVE This paper reports cessation rates observed in SMS Turkey, a text messaging-based smoking cessation program for adult smokers in Ankara, Turkey. METHODS This study was a small-scale, parallel-group randomized controlled trial (RCT) conducted in Ankara, Turkey. Participants were adult daily smokers who were seriously thinking about quitting in the next 15 days and living in Ankara, Turkey. The text messaging intervention, SMS Turkey, provided 6 weeks of daily messages aimed at giving participants skills to help them quit smoking. Messages were sent in an automated fashion, except 2 days and 7 days after the initial quit day. On days 2 and 7, the research assistant manually assigned participants to content "paths" based on whether they were still not smoking or had relapsed. The control arm received a brochure that provided similar information about smoking cessation. The main outcome measure was self-reported 3-month sustained abstinence, verified by carbon monoxide (CO) readings. Neither participants nor researchers were blinded to arm assignment. RESULTS The 151 participants were randomly assigned to 1 of 2 groups: 76 to the SMS Turkey intervention group and 75 to the brochure control group. Using intention to treat, all 151 participants were included in analyses. Three-month cessation trends were not significantly higher in the intervention group: 11% intervention vs 5% control had quit (χ(2)(1)=1.4, P=.24; R(2)=2.0, 95% CI 0.62-6.3). When the sample was stratified by sex, female intervention participants (14%, n=5) were significantly more likely to have quit at 3 months than female control participants (0%, n=0; χ(2)(1)=3.7, P=.05). Among light smokers (ie, those smoking less than 20 cigarettes per day), intervention participants (17%, n=5) also were significantly more likely to have quit compared to control participants (0%, n=0; χ(2)(1)=5.3, P=.02). We noted no difference in cessation rates for males or heavy smokers. Participants experienced significant technology problems during the study. Some participants received duplicate text messages at least once during the trial; others failed to receive some program messages. Neither receiving duplicate messages (χ(2)(1)=0.12, P=.73), or missing 5 or more program messages (χ(2)(1)=0.75, P=.39) negatively affected quitting rates. CONCLUSIONS Although the study was not powered to detect statistically significant differences, as the primary aim was to provide estimates of effect size that could be used to better inform a power analysis for a larger trial, findings provide optimism that SMS Turkey may be able to affect quitting rates in environments with high smoking prevalence, such as Ankara, Turkey. The SMS Turkey software program did not work as well as it did 2 years previous. The system will need to be updated to maintain software compatibility with ongoing technology evolution.

[PMID: 23256730 PMCID: PMC3541201 DOI: 10.1186/1479-5868-9-151] [Citation(s) in RCA: 70] [Impact Index Per Article: 5.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/05/2012] [Accepted: 12/04/2012] [Indexed: 11/11/2022] Open
Abstract
Background To describe the iterative development process and final version of ‘MobileMums’: a physical activity intervention for women with young children (<5 years) delivered primarily via mobile telephone (mHealth) short messaging service (SMS). Methods MobileMums development followed the five steps outlined in the mHealth development and evaluation framework: 1) conceptualization (critique of literature and theory); 2) formative research (focus groups, n= 48); 3) pre-testing (qualitative pilot of intervention components, n= 12); 4) pilot testing (pilot RCT, n= 88); and, 5) qualitative evaluation of the refined intervention (n= 6). Results Key findings identified throughout the development process that shaped the MobileMums program were the need for: behaviour change techniques to be grounded in Social Cognitive Theory; tailored SMS content; two-way SMS interaction; rapport between SMS sender and recipient; an automated software platform to generate and send SMS; and, flexibility in location of a face-to-face delivered component. Conclusions The final version of MobileMums is flexible and adaptive to individual participant’s physical activity goals, expectations and environment. MobileMums is being evaluated in a community-based randomised controlled efficacy trial (ACTRN12611000481976).

Abstract
BACKGROUND Mobile phone text message technology has the potential to improve outcomes for patients with depression and co-morbid Alcohol Use Disorder (AUD). AIMS To perform a randomised rater-blinded trial to explore the effects of supportive text messages on mood and abstinence outcomes for patients with depression and co-morbid AUD. METHODS Participants (n=54) with a DSM IV diagnosis of unipolar depression and AUD who completed an in-patient dual diagnosis treatment programme were randomised to receive twice daily supportive text messages (n=26) or a fortnightly thank you text message (n=28) for three months. Primary outcome measures were Beck's Depression Inventory (BDI-II) scores and Cumulative Abstinence Duration (CAD) in days at three months. TRIAL REGISTRATION NCT0137868. RESULTS There was a statistically significant difference in three month BDI-II scores between the intervention and control groups; 8.5 (SD=8.0) vs. 16.7 (SD=10.3) respectively after adjusting for the baseline scores, F (1, 49)=9.54, p=0.003, η(p)(2)=0.17. The mean difference in change BDI-II scores was -7.9 (95% CI -13.06 to -2.76, Cohen'sd=0.85). There was a trend for a greater CAD in the text message group than the control group: 88.3 (SD=6.2) vs. 79.3 (SD=24.1), t=1.78, df=48, p=0.08. LIMITATIONS Limitations of the study include the small sample size, the potential for loss of rater blinding and the lack of long term follow-up to determine the longer term effects of the intervention. CONCLUSION Supportive text messages have the potential to improve outcomes for patients with comorbid depression and alcohol dependency syndrome.

Abstract
OBJECTIVE To determine the effectiveness of implementation of a prevention programme via mobile phone text messaging in enhancing knowledge, attitudes and practice concerning iodine deficiency and iodized salt consumption. DESIGN In a randomized controlled trial, participants were subjected to a brief tele-educational support regarding iodine deficiency and the importance of iodized salt consumption. The intervention group received daily text messages via mobile phone for 6 weeks. Knowledge, attitude and practice scores, urinary iodine concentration and salt iodine content were assessed at baseline and 8 weeks after the intervention. SETTING Participants were recruited from health-care centres in Tehran, the capital city of Iran. SUBJECTS For the present study 205 females aged ≥18 years were randomly assigned to the intervention (n 95) and control (n 110) groups. RESULTS A significant difference was found in median knowledge scores between the intervention and control groups at follow-up (P = 0.004). There was also a significant difference in median attitude scores between the intervention and control groups (P = 0.02). The intervention group did not differ significantly in median practice score, urinary iodine concentration and salt iodine content from the control group. CONCLUSIONS Text messaging interventions are effective in improving individuals' knowledge and attitudes regarding preventive health-care topics.

Bull World Health Organ 2012; 90:365-72. [PMID: 22589570 DOI: 10.2471/blt.11.099069] [Citation(s) in RCA: 128] [Impact Index Per Article: 10.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/18/2011] [Revised: 01/27/2012] [Accepted: 01/31/2012] [Indexed: 11/27/2022] Open
Abstract
E-health encompasses a diverse set of informatics tools that have been designed to improve public health and health care. Little information is available on the impacts of e-health programmes, particularly in low- and middle-income countries. We therefore conducted a scoping review of the published and non-published literature to identify data on the effects of e-health on health outcomes and costs. The emphasis was on the identification of unanswered questions for future research, particularly on topics relevant to low- and middle-income countries. Although e-health tools supporting clinical practice have growing penetration globally, there is more evidence of benefits for tools that support clinical decisions and laboratory information systems than for those that support picture archiving and communication systems. Community information systems for disease surveillance have been implemented successfully in several low- and middle-income countries. Although information on outcomes is generally lacking, a large project in Brazil has documented notable impacts on health-system efficiency. Meta-analyses and rigorous trials have documented the benefits of text messaging for improving outcomes such as patients' self-care. Automated telephone monitoring and self-care support calls have been shown to improve some outcomes of chronic disease management, such as glycaemia and blood pressure control, in low- and middle-income countries. Although large programmes for e-health implementation and research are being conducted in many low- and middle-income countries, more information on the impacts of e-health on outcomes and costs in these settings is still needed.

Abstract
CONTEXT Little research exists about adolescents' and young adults' use of new media technologies to communicate about sexual health. Understanding how young people at high risk for STDs use these technologies can inform media-based interventions. METHODS Between October 2010 and March 2011, a sample of 94 low-income, parenting adolescents and young adults recruited at clinics in Connecticut completed an audio computer-assisted self-interview about their use of media technologies, communication with friends about sexual health and willingness to use media technologies for such communication. Descriptive statistics were calculated; characteristics of those willing and those unwilling to communicate were compared in chi-square, t and Mann-Whitney tests. RESULTS Ninety-three percent of participants had mobile phones; 71% used Facebook regularly. Participants discussed sexual health more often with close friends than with casual friends, and preferred to have such conversations in person (71% with close friends and 68% with casual friends), over the phone (52% and 45%) or via text message (30% and 28%), rather than through social networking sites (0-9% and 2-7%). Fewer than one-third reported being willing to share sexual health information with friends through a specific new media technology. Those who were willing were predominantly black (59%); of those who were unwilling, 51% were Latino. Condom self-efficacy, STD knowledge and number of Facebook friends were greater among those who were willing than among those who were unwilling. CONCLUSIONS For conversations about sexual health, young urban parents prefer private forms of communication; thus, social networking sites may not aid STD interventions.

Abstract
OBJECTIVES Nonadherence to prescribed medications impairs therapeutic benefits. The authors measured the ability of an automated text messaging (short message service [SMS]) system to improve adherence to postdischarge antibiotic prescriptions. METHODS This was a randomized controlled trial in an urban emergency department (ED) with an annual census of 65,000. A convenience sample of adult patients being discharged with a prescription for oral antibiotics was enrolled. Participants received either a daily SMS query about prescription pickup, and then dosage taken, with educational feedback based on their responses (intervention), or the usual printed discharge instructions (control). A standardized phone follow-up interview was used on the day after the intended completion date to determine antibiotic adherence: 1) the participant filled prescription within 24 hours of discharge and 2) no antibiotic pills were left on the day after intended completion of prescription. RESULTS Of the 200 patients who agreed to participate, follow-up was completed in 144 (72%). From the 144, 26% (95% confidence interval [CI] = 19% to 34%) failed to fill their discharge prescriptions during the first 24 hours, and 37% (95% CI = 29% to 45%) had pills left over, resulting in 49% (95% CI = 40% to 57%) nonadherent patients. There were no differences in adherence between intervention participants and controls (57% vs. 45%; p = 0.1). African American race, greater than twice-daily dosing, and self-identifying as expecting to have difficulty filling or taking antibiotics at baseline were associated with nonadherence. CONCLUSIONS Almost one-half (49%) of our patients do not adhere to antibiotic prescriptions after ED discharge. Future work should improve the design and deployment of SMS interventions to optimize their effect on improving adherence to medication after ED discharge.

Abstract
This study was aimed to explore women's and midwives' views on the use of mobile technology in supporting obese pregnant women with healthy lifestyle choices. A purposive sample of 14 women and midwives participated in four focus groups in Doncaster, UK. A content analysis of the transcripts from the first focus group led to the emergence of three main constructs with associated subcategories including Benefits ("modernising," "motivating," "reminding," and "reducing" the sense of isolation), Risks and Limitations (possibility of "being offensive," "creating pressure or guilt," and "being influenced by mood"), and Service Delivery (making it "available to all pregnant women," giving attention to the "message tone" and development of "message content"). They also suggested the use of other modalities such as web-based services for weight management during pregnancy. Based on the above results a text messaging service was developed and presented to the 2nd focus group participants who confirmed the positive views from the first focus group on the use of the text messaging as being supportive and informative. The participants also welcomed "women's engagement and choice" in deciding the content, timing and frequency of messages. The results informed the development of a text messaging service to support maternal obesity management. The implementation and acceptability of this service requires further investigation.

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. This omission is of particular concern because many researchers seem to view text messaging as the intervention itself instead of simply a delivery mechanism. Certainly, aspects of this technology may increase participant engagement. Like other interventions, however, the content is a central driver of the behavior change. OBJECTIVE To address this noted gap in the literature, we discuss the protocol decisions and content development for SMS Turkey (or Cebiniz birakin diyor in Turkish), a smoking cessation text messaging program for adult smokers in Turkey. METHODS Content was developed in English and translated into Turkish. Efforts were made to ensure that the protocol and content were grounded in evidence-based smoking cessation theory, while also reflective of the cultural aspects of smoking and quitting in Turkey. RESULTS Methodological considerations included whether to provide cell phones and whether to reimburse participants for texting costs; whether to include supplementary intervention resources (eg, personal contact); and whether to utilize unidirectional versus bidirectional messaging. Program design considerations included how messages were tailored to the quitting curve and one's smoking status after one's quit date, the number of messages participants received per day, and over what period of time the intervention lasted. CONCLUSION The content and methods of effective smoking cessation quitline programs were a useful guide in developing SMS Turkey. Proposed guidelines in developing text messaging-based behavior change programs are offered.

Feasibility of a randomized controlled trial to evaluate Text Reminders for Immunization Compliance in Kids (TRICKs). Vaccine 2012; 30:5305-9.

Abstract
OBJECTIVE To pilot test the Text Reminders for Immunization Compliance in Kids (TRICKs) program to evaluate its feasibility and potential to increase immunization coverage. DESIGN Randomized controlled trial (RCT). SETTING Pediatric clinic. PARTICIPANTS Parents of newborns being discharged from a local hospital who intended to seek child health care at the University-sponsored pediatric resident and faculty clinic. INTERVENTION Text message immunization reminders prior to immunization due dates. MAIN OUTCOME MEASURES Receipt and timeliness of immunizations at 2, 4 and 6 months of age. RESULTS Participants (N=90) were English (83%) or Spanish (17%) speaking. The majority were female (83%), on public insurance (59%), and had adequate health literacy (96%). Parents were married or a member of an unmarried couple (62%). Over 66% had a high school diploma or less. Greater numbers of intervention children received immunizations and were "on time" using per protocol analysis; though not statistically significance. Limitations include sample size, problematic text messaging software, and loss of phone service at 7 months for 40% of intervention parents. However, post-intervention interviews (N=18) indicated strong support for TRICKs; 83% found the text message reminders very helpful and 17% somewhat helpful. DISCUSSION Pilot testing allowed us to assess processes, including recruitment, retention, and software, which will increase the success of an RCT. Software with built-in backup systems is needed for follow-up when mobile service is interrupted. However, in spite of limitations, immunization rates were higher in the text message reminder group, though not statistically significant. Parent support and interest was high. A fully powered RCT is needed with follow-up over the full 4-3-1-3-3-1 series. Based on our results, for 80% power where we expected 90% compliance in the intervention group and 80% in the control group we need 219 per group, plus increases to address drop out and loss of follow-up.

Abstract
Sickle cell disease, the most common hemoglobinopathy in the world, affects patient lives from early childhood. Effective care of sickle cell disease requires frequent medical monitoring, such as tracking the frequency, severity, and duration of painful events. Conventional monitoring includes paper- or web-based reporting diaries. These systems require that patients carry forms, which are easily lost, or laptop computers, which are impractical to scale to large populations. Both are prone to sporadic use by older adolescents due to lack of reminders. In this paper, we design and prototype a Sickle cell disease REporting and MOnitoring TElemedicine system (SickleREMOTE), aiming to resolve limitations of conventional monitoring diaries. This monitoring system is configured as automated short message service text (SMS-text) messages that arrive at a mobile phone anywhere on a cellular network. The messages may be reminders to encourage treatment adherence or questionnaires to collect self-assessed clinical data relating to treatment adjustments. Patients respond to the messages using pre-determined templates and a cloud database parses and stores messages automatically. Providers use a web-based interface to view, analyze, and download collected data. SickleREMOTE is developed by Georgia Institute of Technology in conjunction with Children's Healthcare of Atlanta (CHOA). System effectiveness will be evaluated using a trial of 30 adolescents with sickle cell disease and measured by response rate, time to response, error rate, and correspondence with data collected by telephone calls.

[PMID: 22522112 PMCID: PMC3376516 DOI: 10.2196/jmir.1950] [Citation(s) in RCA: 113] [Impact Index Per Article: 9.4] [Reference Citation Analysis] [Abstract] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/27/2011] [Revised: 03/08/2012] [Accepted: 03/08/2012] [Indexed: 01/19/2023] Open
Abstract
Background Website-delivered physical activity interventions are successful in producing short-term behavior change. However, problems with engagement and retention of participants in these programs prevent long-term behavior change. New ways of accessing online content (eg, via smartphones) may enhance engagement in these interventions, which in turn may improve the effectiveness of the programs. Objective To measure the potential of a newly developed smartphone application to improve health behaviors in existing members of a website-delivered physical activity program (10,000 Steps, Australia). The aims of the study were to (1) examine the effect of the smartphone application on self-monitoring and self-reported physical activity levels, (2) measure the perceived usefulness and usability of the application, and (3) examine the relationship between the perceived usefulness and usability of the application and its actual use. Methods All participants were existing members of the 10,000 Steps program. We recruited the intervention group (n = 50) via email and instructed them to install the application on their smartphone and use it for 3 months. Participants in this group were able to log their steps by using either the smartphone application or the 10,000 Steps website. Following the study, the intervention group completed an online questionnaire assessing perceived usability and usefulness of the smartphone application. We selected control group participants (n = 150), matched for age, gender, level of self-monitoring, preintervention physical activity level, and length of membership in the 10,000 Steps program, after the intervention was completed. We collected website and smartphone usage statistics during the entire intervention period. Results Over the study period (90 days), the intervention group logged steps on an average of 62 days, compared with 41 days in the matched group. Intervention participants used the application 71.22% (2210/3103) of the time to log their steps. Logistic regression analyses revealed that use of the application was associated with an increased likelihood to log steps daily during the intervention period compared with those not using the application (odds ratio 3.56, 95% confidence interval 1.72–7.39). Additionally, use of the application was associated with an increased likelihood to log greater than 10,000 steps on each entry (odds ratio 20.64, 95% confidence interval 9.19–46.39). Linear regression analysis revealed a nonsignificant relationship between perceived usability (r = .216, P = .21) and usefulness (r = .229, P = .17) of the application and frequency of logging steps in the intervention group. Conclusion Using a smartphone application as an additional delivery method to a website-delivered physical activity intervention may assist in maintaining participant engagement and behavior change. However, due to study design limitations, these outcomes should be interpreted with caution. More research, using larger samples and longer follow-up periods, is needed to replicate the findings of this study.

Improving adherence to antiretroviral therapy for youth living with HIV/AIDS: a pilot study using personalized, interactive, daily text message reminders. J Med Internet Res 2012; 14:e51. [PMID: 22481246 PMCID: PMC3376506 DOI: 10.2196/jmir.2015] [Citation(s) in RCA: 150] [Impact Index Per Article: 12.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/26/2011] [Revised: 01/18/2012] [Accepted: 01/19/2012] [Indexed: 12/31/2022] Open
Abstract
BACKGROUND For youth living with human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome (AIDS), nonadherence to antiretroviral therapy (ART) can lead to poor health outcomes and significantly decreased life expectancy. OBJECTIVE To evaluate the feasability, acceptability, and preliminary efficacy of short message service (SMS) or text message reminders to improve adherence to ART for youth living with HIV/AIDS. METHODS We conducted this prospective pilot study using a pre-post design from 2009 to 2010 at a community-based health center providing clinical services to youth living with HIV/AIDS. Eligibility criteria included HIV-positive serostatus, age 14-29 years, use of a personal cell phone, English-speaking, and being on ART with documented poor adherence. During the 24-week study period, participants received personalized daily SMS reminders and a follow-up message 1 hour later assessing whether they took the medication, and asking participants to respond via text message with the number 1 if they took the medication and 2 if they did not. Outcome measures were feasibility, acceptability, and adherence. Self-reported adherence was determined using the visual analog scale (VAS) and AIDS Clinical Trial Group (ACTG) questionnaire 4-day recall. Viral load and CD4 cell count were followed as biomarkers of adherence and disease progression at 0, 12, and 24 weeks. RESULTS Participants (N = 25) were mean age 23 (range 14-29) years, 92% (n = 23) male, 60% (n = 15) black, and 84% (n = 21) infected through unprotected sex. Mean VAS scores significantly increased at 12 and 24 weeks in comparison with baseline (week 0: 74.7, week 12: 93.3, P < .001; week 24: 93.1, P < .001). ACTG questionnaire 4-day recall also improved (week 0: 2.33, week 12: 3.24, P = .002; week 24: 3.19, P = .005). There was no significant difference in CD4 cell count or viral load between baseline and 12- or 24-week follow-up, although there was a trend toward improvement of these biomarkers and a small to moderate standardized effect size (range of Cohen d: -0.51 to 0.22). Of 25 participants, 21 (84%) were retained, and 20 of the 21 (95%) participants who completed the study found the intervention helpful to avoid missing doses. CONCLUSIONS In this pilot study, personalized, interactive, daily SMS reminders were feasible and acceptable, and they significantly improved self-reported adherence. Larger controlled studies are needed to determine the impact of this intervention on ART adherence and other related health outcomes for youth living with HIV/AIDS.

Vandelanotte C, Duncan MJ, Plotnikoff RC, Mummery WK. Do participants' preferences for mode of delivery (text, video, or both) influence the effectiveness of a Web-based physical activity intervention? J Med Internet Res 2012; 14:e37. [PMID: 22377834 PMCID: PMC3374539 DOI: 10.2196/jmir.1998] [Citation(s) in RCA: 23] [Impact Index Per Article: 1.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/16/2011] [Revised: 01/29/2012] [Accepted: 02/06/2012] [Indexed: 12/04/2022] Open
Abstract
Background In randomized controlled trials, participants cannot choose their preferred intervention delivery mode and thus might refuse to participate or not engage fully if assigned to a nonpreferred group. This might underestimate the true effectiveness of behavior-change interventions. Objective To examine whether receiving interventions either matched or mismatched with participants’ preferred delivery mode would influence effectiveness of a Web-based physical activity intervention. Methods Adults (n = 863), recruited via email, were randomly assigned to one of three intervention delivery modes (text based, video based, or combined) and received fully automated, Internet-delivered personal advice about physical activity. Personalized intervention content, based on the theory of planned behavior and stages of change concept, was identical across groups. Online, self-assessed questionnaires measuring physical activity were completed at baseline, 1 week, and 1 month. Physical activity advice acceptability and website usability were assessed at 1 week. Before randomization, participants were asked which delivery mode they preferred, to categorize them as matched or mismatched. Time spent on the website was measured throughout the intervention. We applied intention-to-treat, repeated-measures analyses of covariance to assess group differences. Results Attrition was high (575/863, 66.6%), though equal between groups (t863 =1.31, P =.19). At 1-month follow-up, 93 participants were categorized as matched and 195 as mismatched. They preferred text mode (493/803, 61.4%) over combined (216/803, 26.9%) and video modes (94/803, 11.7%). After the intervention, 20% (26/132) of matched-group participants and 34% (96/282) in the mismatched group changed their delivery mode preference. Time effects were significant for all physical activity outcomes (total physical activity: F2,801 = 5.07, P = .009; number of activity sessions: F2,801 = 7.52, P < .001; walking: F2,801 = 8.32, P < .001; moderate physical activity: F2,801 = 9.53, P < .001; and vigorous physical activity: F2,801 = 6.04, P = .002), indicating that physical activity increased over time for both matched and mismatched groups. Matched-group participants improved physical activity outcomes slightly more than those in the mismatched group, but interaction effects were not significant. Physical activity advice acceptability (content scale: t368 = .10, P = .92; layout scale: t368 = 1.53, P = .12) and website usability (layout scale: t426 = .05, P = .96; ease of use scale: t426 = .21, P = .83) were generally high and did not differ between the matched and mismatched groups. The only significant difference (t621 = 2.16, P = .03) was in relation to total time spent on the website: the mismatched group spent significantly more time on the website (14.4 minutes) than the matched group (12.1 minutes). Conclusion Participants’ preference regarding delivery mode may not significantly influence intervention outcomes. Consequently, allowing participants to choose their preferred delivery mode may not increase effectiveness of Web-based interventions.

Abstract
Sexual behaviour studies are often challenged by sampling, participation and measurement biases, and may be unacceptable to participants. We invited 293 randomly selected female sex workers (FSWs) in Bangalore, India, to participate in a telephone survey, with condom breakage as the main outcome. Free cell phones were supplied and trained interviewers telephoned FSWs daily to ask about all sex acts the previous day. Later, we undertook focus groups to discuss the methodology with the participants. We evaluated technical and operational feasibility; data reliability and measurement error; emotional and fatigue effects; interviewer bias; survey reactivity effects; and user acceptability. Response rates were high, with 84% of invited participants complying fully with the protocol. The study ran smoothly, with little evidence of biases. The methodology was highly acceptable; the respondents enjoyed using a new telephone and being interviewed at times convenient to them. Other reasons for the success of the method were that the study was sanctioned and supported by the sex worker collective, and the interviewers were well trained and developed a strong rapport with the participants. The success of this methodology, and the wealth of data produced, indicates that it can be an important tool for conducting sexual behaviour research in low literacy, high sex volume populations.

Abstract
OBJECTIVE South Africa has one of the highest human immunodeficiency virus (HIV) prevalence rates in the world, but despite the well-established benefits of HIV counseling and testing (HCT), there is low uptake of HCT. The study aimed to investigate the effectiveness of using short message services (SMSs) to encourage HCT while interrogating the impact of altering SMS content and dosage (the number of SMSs). MATERIALS AND METHODS About 2,533 participants were recruited via an SMS sent to 24,000 mobiles randomly sampled from a pre-existing database. Recruits were randomly allocated to four intervention groups that received 3 or 10 informational (INFO) or motivational (MOTI) SMSs, and a control group. After the intervention, participants were prompted to go for HCT, and postintervention assessment was done after 3 weeks. RESULTS In comparison with the control, receipt of 10 MOTI messages had the most impact on uptake of HCT with a 1.7-fold increased odds of testing (confidence interval 95%; p=0.0036). The lack of efficacy of three SMSs indicates a threshold effect, that is, a minimum number of MOTI SMSs is required. INFO SMSs, whether 3 or 10 were sent, did not have a statistically significant effect. The cost can be calculated for the marginal effect of the SMSs, that is, the cost to get people to test over and above those who were likely to test without the intervention. Use of 10 MOTI SMSs yielded a cost-per-tester of $2.41. CONCLUSIONS While there are methodological issues apparent in our study, the results demonstrate the potential of SMSs to influence the uptake of HCT, the importance of appropriate content, and the need to determine a threshold for SMS-based interventions. These results indicate a potential for SMSs to be used more generally for interventions encouraging people to take health-related actions, and the need for further research in this field. The reasonable cost-per-tester is promising for the scale-up of such an intervention.

Abstract
Mobile technology enhances the potential to assess, prompt, educate, and engage individuals with diabetes. The near-ubiquitous presence of mobile phones allows real-time contextually relevant support for diabetes self-care. We review the design of mobile interventions included in a recent meta-analysis. Although mobile programs can lead to improvements in glycemic control, many aspects, such as the role of the diabetes clinician, real-time features, and patient engagement have not been documented. Studies with the greatest impact on hemoglobin A(1c) integrated patient feedback and a role for clinicians. Research is needed regarding feasible and efficacious roles for clinical support in mobile interventions. Recommendations for design and research include the following: consideration of patient and clinician burden; identification of patterns and metrics for patient treatment adherence and engagement; integration of goal setting and problem solving; enhancing patient education; a greater focus on patient-centered motivational strategies; and utilization of study designs that relate intervention design elements to outcomes.
