Monetary incentives for improving smartphone-measured oral hygiene behaviors in young children: A randomized pilot trial.

ABSTRACT:

Aims

To assess feasibility, acceptability, and early efficacy of monetary incentive-based interventions on fostering oral hygiene in young children measured with a Bluetooth-enabled toothbrush and smartphone application.

Design

A stratified, parallel-group, three-arm individually randomized controlled pilot trial.

Setting

Two Los Angeles area Early Head Start (EHS) sites.

Participants

36 parent-child dyads enrolled in an EHS home visit program for 0-3 year olds.

Interventions

Eligible dyads, within strata and permuted blocks, were randomized in equal allocation to one of three groups: waitlist (delayed monetary incentive) control group, fixed monetary incentive package, or lottery monetary incentive package. The intervention lasted 8 weeks.

Outcomes

Primary outcomes were a) toothbrushing performance: mean number of Bluetooth-recorded half-day episodes per week when the child's teeth were brushed, and b) dental visit by the 2-month follow-up among children with no prior dental visit. The a priori milestone of 20% more frequent toothbrushing identified the intervention for a subsequent trial. Feasibility and acceptability measures were also assessed, including frequency of parents syncing the Bluetooth-enabled toothbrush to the smartphone application and plaque measurement from digital photographs.

Findings

Digital monitoring of toothbrushing was feasible. Mean number of weekly toothbrushing episodes over 8 weeks was 3.9 in the control group, 4.1 in the fixed incentive group, and 6.0 in the lottery incentive group. The lottery group had 53% more frequent toothbrushing than the control group and 47% more frequent toothbrushing than the fixed group. Exploratory analyses showed effects concentrated among children ≤24 months. Follow-up dental visit attendance was similar across groups. iPhone 7 more reliably captured evaluable images than Photomed Cannon G16.

Conclusions

Trial protocol and outcome measures were deemed feasible and acceptable. Results informed the study protocol for a fully powered trial of lottery incentives versus a delayed control using the smart toothbrush and remote digital incentive program administration.

Project description:ObjectiveThis mixed methods study explores gender differences in, and reasons for, toothbrushing and flossing among Mexican-origin adults.MethodsInterviews and surveys about oral hygiene behaviors were collected from 72 adults (ages 21-40) living on the California-Mexico border. Interviews were audio-recorded, transcribed in their original language (English/Spanish), then coded. Survey responses were linked to coded transcripts in Dedoose. Qualitative reports were thematically analyzed for each behavior, stratified into four groups by gender and whether or not participants met American Dental Association (ADA) weekly guidelines (brushing ≥ 14/week; flossing ≥ 7/week). Self-reported weekly frequencies of brushing and flossing were collected continuously, and then dichotomized as meeting guidelines or not. Kruskal-Wallis and chi-square tests assessed differences in hygiene behavior frequency by gender. Negative binomial and logistic regressions were performed, accounting for socio-demographic characteristics.ResultsOverall, 76% and 40% of adults met ADA guidelines for brushing and flossing, respectively. There were no differences in meeting ADA guidelines by gender. When brushing was examined continuously, women brushed 1.24 (1.05-1.47; p = 0.0099) times the rate of weekly brushing than men in the full model; flossing frequency differences were not found. Men and women, whether ADA guidelines were met or not, identified similar brushing and flossing facilitators (health concerns, aesthetics), and barriers (lack of time, not being home). Some women (mothers) were motivated to brush to be role models for their children. Self-efficacy, or confidence in ability to brush or floss, was described differently by adults who met ADA guidelines (high self-efficacy) compared to the adults not meeting guidelines (low self-efficacy).ConclusionsIntegrating quantitative and qualitative data obtained from Mexican-origin adults identified few differences in both oral hygiene behaviors and the factors that influence their enactment.

Project description:Cigarette smoking during pregnancy increases risk for pregnancy complications, growth restriction, and other adverse health outcomes. The most effective intervention for reducing smoking during pregnancy is financial incentives contingent on biochemically-verified smoking abstinence. The present study examined the efficacy of a smartphone-based intervention whereby smoking monitoring and incentive delivery occurred remotely using a mobile app. If efficacious, this remote intervention would allow pregnant women residing in geographically remote areas to benefit from incentives-based cessation interventions. Sixty U.S. pregnant smokers were recruited between May 2018 to May 2019 via obstetrical clinics, Women, Infants, and Children (WIC) offices, and Facebook. Participants were assigned sequentially to one of two treatments: best practices alone (N = 30) or best practices plus financial incentives (N = 30). Outcomes were analyzed using repeated measures analysis based on generalized estimating equations (GEE). Seven-day point prevalence abstinence rates were greater in the incentives versus best practices arms early- (46.7% vs 20.0%, OR = 3.50, 95%CI = 1.11,11.02) and late-antepartum (36.7% vs 13.3%, OR = 3.76, 95%CI = 1.04,13.65), and four- (36.7% vs 10.0%, OR = 5.21, 95%CI = 1.28,21.24) and eight-weeks postpartum (40.0% vs 6.7%, OR = 9.33, 95%CI = 1.87,46.68), although not at the 12- (23.3% vs 10.0%, OR = 2.74, 95%CI = 0.63,11.82) or 24-week (20.0% vs 6.7%, OR = 3.50, 95%CI = 0.65,18.98) postpartum assessments likely due to this pilot study being underpowered for discerning differences at the later assessments, especially 24-weeks postpartum which was three months after treatment completion. These results support the efficacy of this remote, incentives-based intervention for pregnant smokers. Further research evaluating its efficacy and cost-effectiveness in a well-powered, randomized controlled trial appears warranted.

Project description:BackgroundNursing home residents with dementia are often dependent on others for mouth care, yet will react with care-resistant behavior when receiving assistance. The oral health of these elders deteriorates in the absence of daily oral hygiene, predisposing them to harmful systemic problems such as pneumonia, hyperglycemia, cardiac disease, and cerebral vascular accidents. The purpose of this study is to determine whether care-resistant behaviors can be reduced, and oral health improved, through the application of an intervention based on the neurobiological principles of threat perception and fear response. The intervention, called Managing Oral Hygiene Using Threat Reduction, combines best mouth care practices with a constellation of behavioral techniques that reduce threat perception and thereby prevent or de-escalate care-resistant behaviors.Methods/designUsing a randomized repeated measures design, 80 elders with dementia from 5 different nursing homes will be randomized at the individual level to the experimental group, which will receive the intervention, or to the control group, which will receive standard mouth care from research team members who receive training in the proper methods for providing mouth care but no training in resistance recognition or prevention/mediation. Oral health assessments and care-resistant behavior measurements will be obtained during a 7-day observation period and a 21-day intervention period. Individual growth models using multilevel analysis will be used to estimate the efficacy of the intervention for reducing care-resistant behaviors in persons with dementia, and to estimate the overall efficacy of the intervention using oral health outcomes. Activity-based costing methods will be used to determine the cost of the proposed intervention.DiscussionAt the conclusion of this study, the research team anticipates having a proven intervention that prevents and reduces care-resistant within the context of mouth care. Long-term objectives include testing the effect of the intervention on systemic illnesses among persons with dementia; examining the transferability of this intervention to other activities of daily living; and disseminating threat reduction interventions to nursing home staff, which may radically change the manner in which care is provided to persons with dementia.Trial registrationClinicalTrials.gov: NCT01363258.
