“…Overall, MVCN members reported infrequent use of the network, with approximately one-third of survey participants not having visited it in the past 3 months. Similar levels of use were reported in another study of a Web-based community for a smoking cessation program in which approximately one-third of participants never visited the community [ 18 ]. Moreover, only 24.2% (51/211) of MVCN members reported using the website once a week or more.…”

BackgroundWeb-based peer support interventions have shown promise in reducing social isolation and social support deficits among informal caregivers, but little research has examined how caregivers use and perceive these interventions.ObjectiveIn this study, we examined utilization and perceptions of a Web-based social support intervention for informal caregivers of wounded, ill, and injured United States military service members and veterans.MethodsThis was a mixed-methods study that used quantitative survey data and qualitative data from focus groups and interviews with informal caregivers enrolled in a Web-based peer support intervention to explore their use and perceptions of the intervention. The intervention was delivered via a website that featured interest groups organized around specific topics, webinars, webchats, and messaging functionality and was moderated by professionally trained peers. This study occurred in the context of a quasi-experimental outcome evaluation of the intervention, where intervention participants were compared with a group of military caregivers who were not enrolled in the intervention.ResultsSurvey findings indicated that caregivers used the website infrequently, with 60.7% (128/211) visiting the website once a month or less, and passively, with a minority (32/144, 22.2%) of users (ie, those who had visited the website at least once during the past 3 months, N=144) posting comments or links to the network. Nonetheless, most users (121/144, 84.0%) endorsed moderate or greater satisfaction with the website on the survey, and focus group and interview participants reported benefiting sufficiently from passive use of the website (eg, reading posts). Quantitative and qualitative findings suggested that users viewed the website primarily as a source of informational support. Among 63.2% (91/144) of users who completed the survey, the most commonly reported network-related activity was obtaining information from the network’s resource library, and focus group and interview participants viewed the network primarily as an informational resource. Focus group and interview participants expressed an unmet need for emotional support and the desire for a more personal touch in the forms of more active engagement with other caregivers in the network and the creation of local, in-person support groups for caregivers.ConclusionsThese findings suggest that Web-based peer support interventions may lend themselves better to the provision of informational (vs emotional) support and may need to be supplemented by in-person peer support groups to better meet caregivers’ needs for emotional support.

Background Partial adherence in Internet smoking cessation interventions presents treatment and evaluation challenges. Increasing adherence may improve outcomes. Purpose To present smoking outcomes from an Internet randomized trial of two strategies to encourage adherence to tobacco dependence treatment components (i.e., skills training, social support, medication): 1) a social network (SN) strategy to integrate smokers into an online community, and 2) free nicotine replacement therapy (NRT). In addition to intent-to-treat analyses, we used novel statistical methods to distinguish the impact of treatment assignment from treatment utilization. Methods N=5,290 current smokers on a cessation website (WEB) were randomized to WEB, WEB+SN, WEB+NRT, or WEB+SN+NRT. The main outcome was 30-day point prevalence abstinence at 3 and 9 months post-randomization. Adherence measures included website metrics of skills training and community use, and self-reported medication use. Inverse Probability of Retention Weighting and Inverse Probability of Treatment Weighting jointly addressed dropout and treatment selection. Propensity weights were used to calculate Average Treatment effects on the Treated. Results Treatment assignment analyses showed no effects on abstinence for either adherence strategy. Treatment utilization analyses revealed that joint community and medication use yielded large percentage point increases in 3-month abstinence rates over skills training alone across arms: WEB=20.6 (95% CI=10.8, 30.4), WEB+SN=19.2 (95% CI=11.1, 27.3), WEB+NRT=13.1 (95% CI=4.1, 22.0), and WEB+SN+NRT=20.0 (95% CI=12.2, 27.7). Abstinence rates among participants that used all treatment components were 25.7%-32.2%. Conclusions Novel propensity weighting approaches can serve as a model for establishing efficacy of Internet interventions and yield important insights about mechanisms.
