This is the protocol for an updated Campbell systematic review. The objectives are as follows: To evaluate the effect of behavioral interventions on smoking cessation among homeless individuals.

INTRODUCTION/OBJECTIVE: National guidelines emphasize the importance of annual immunization for patients living with rheumatoid arthritis (RA), but vaccination rates remain suboptimal in this population. Evaluating the efficacy of patient and/or provider-targeted interventions to improve vaccination uptake among RA patients could inform practice. METHODS: We conducted a systematic review (SR) to examine the efficacy of interventions (exposure) aiming to improve vaccination uptake in patients with RA (outcome). English and French language, peer-reviewed interventional studies to improve vaccination rates in RA patients published between 2009 and 2018 were included. RESULTS: The search yielded a total of 450 records. Five articles met inclusion criteria. All interventions focused on changing provider behavior using some form of vaccination reminder as the primary intervention strategy, though only two studies reported provider prescribing behavior as an outcome (which was 4% and 58%). Overall, studies varied greatly regarding intervention delivery mode (e.g., educational sessions, e-mail reminders, best practice alerts), and behavior change techniques used to encourage providers to prescribe vaccination (e.g., feedback and monitoring, shaping knowledge, self-regulation). For influenza, pneumococcal and herpes zoster, post-intervention (mean 12-16 months follow-up) vaccination rates increased by a mean of 16.6% (+/- 15.4%). CONCLUSIONS: Interventions to enhance vaccine uptake in RA focused almost exclusively on improving provider prescription of vaccines using reminder-type interventions. Although effective in improving vaccination rates, those studies used heterogeneous interventions and behavior change techniques. Few studies measured provider prescribing behavior as an outcome. Future studies targeting providers should measure relevant provided-related outcomes and their impact on patient outcomes, to determine overall efficacy.

OBJECTIVE: Behavioral sleep interventions are regularly used to improve sleep problems experienced by children with autism spectrum disorder (ASD) and/or intellectual disability (ID). Recent developments have seen the introduction of parent sleep education and healthy sleep practice training to sleep interventions. This article aims to systematically review the evidence on the efficacy of parent training that is incorporated within recent sleep interventions for children with ASD and/or ID. METHOD: Electronic databases and manual searches of reference lists identified 11 studies (n = 416 children) that met the inclusion criteria. RESULTS: The evidence presented in this systematic review would suggest that the inclusion of parent training within behavioral sleep interventions for children with ASD and/or ID is generally effective and valued by parents. Nine of the 11 studies reviewed reported a reduction in sleep problems. CONCLUSION: The literature conveys an emerging evidence-based practice that could contribute to future behavioral sleep research and guide best-practice decisions to support effective parent training to improve sleep outcomes for children with ASD and/or ID.
