Culturally Tailored Messages and Trial Registry Enrollment

Marginalized populations have lower levels of clinical trial representation than other populations. Tailoring recruitment materials and providing incentives may improve representation. To determine whether culturally tailored video improves parents' decision to enroll (DTE) Black children in a research registry. A randomized clinical trial, using mixed methods and consecutive sampling, was conducted in an urban primary care pediatric clinic. A post hoc study assessed the association of a monetary incentive with DTE. Ninety-three parents were recruited before their child's scheduled clinic visit. Participants completed a survey during which they were randomly assigned to review a paragraph (control group), generic video, or tailored video and received a gift card. Video watchers completed questions about its effectiveness. All participants were invited to join the registry. In the post hoc study, consenting participants followed the control group protocol and the coordinator promised them an ink pen for participating. The study was conducted between November 15, 2022, and August 29, 2023. A survey regarding the importance of being included in research studies was administered after participants watched a culturally tailored video. The primary outcome was DTE. Covariates were message effectiveness, clinical trial knowledge, and trust. Intention-to-treat analysis was performed. A total of 125 individuals were included. All groups had similar mean (SD) parent age (overall, 32.6 [7.35] years), gender (110 [88.0%] women), and race (116 [92.8%] Black or African American). There was no significant difference in the odds of DTE between the appeal video and control (odds ratio [OR], 1.19; 95% CI, 0.38-3.72) or between the generic video and control (OR, 1.91; 95% CI, 0.54-6.71). However, DTE was higher for all 3 gift card groups vs the ink pen incentive group (eg, control vs ink pen incentive: OR, 5.01; 95% CI, 1.68-14.95). After adjusting for trust, monetary incentives were associated with higher odds of DTE (adjusted OR, 5.92; 95% CI, 2.44-14.39). In this randomized clinical trial, targeted messaging was not associated with a higher decision to enroll in a pediatric clinical trial registry. There may be a role for combining holistic messaging with monetary incentives to improve enrollment. ClinicalTrials.gov Identifier: NCT06138145.

Comparison of Two Financial Incentives to Encourage the Use of Adalimumab Biosimilars: Results of a French Experiment Close to Clinicians.

In 2018, the French government introduced two mutually exclusive financial incentives to increase etanercept and insulin glargine biosimilar use. The general case redirects 20% of the price difference between the reference product and its biosimilars to hospitals for every biosimilar dispensed in community pharmacies from hospital prescriptions. The experimental case redirects 30% to prescribing clinical units after hospital selection. Adalimumab was added to these incentives in 2019, after its first biosimilar was launched. This retrospective observational study aimed to compare both general and experimental incentives after 19 months to assess the impact of directly incentivizing clinical units for adalimumab biosimilars. The monthly number of adalimumab boxes dispensed in community pharmacies was linked to the corresponding hospital's prescription using IQVIA Xponent data from November 2017 to October 2020. The monthly mean rate of adalimumab biosimilars was compared between incentive groups and subgroups depending on hospitals' prior experience with the etanercept experimental case. General case hospitals had a significantly lower mean biosimilar uptake (16.7% vs 23.2%, p = 0.029) than those included in the experimental case. Twenty-three of the 40 hospitals in the experimental case and ten out of the 91 hospitals studied in the general case had already taken part in the etanercept experiment. Biosimilar uptake was higher, but not statistically significant, for hospitals with prior experience in the adalimumab general case group (p = 0.086). This study confirmed that incentivizing close to physicians was more effective in increasing the biosimilar rate. It also suggested that previous incentive experience positively influenced biosimilar penetration.

The Influence of Incentive-Based Mobile Fitness Apps on Users' Continuance Intention With Gender Moderation Effects: Quantitative and Qualitative Study.

A survey conducted by McKinsey & Company reported that, as of May 2022, as many as 26% of Indonesians had recently started to engage actively in physical activity, 32% undertook regular physical activity, and 9% exercised intensely. The Fourth Industrial Revolution has spurred the rapid development of mobile fitness apps (MFAs) used to track people's sports activities. However, public interest in using these apps for any length of time is still relatively low. In this study, we aimed to determine the effect of incentives (eg, self-monitoring, social support, platform rewards, and external influence) on the use of MFAs and the moderating effect of gender on users' continuance usage intention. The study used a mixed methods approach. Quantitative data were collected through a web-based questionnaire and qualitative data from interviews with 30 respondents. The quantitative data, collected from 379 valid responses, were processed using covariance-based structural equation modeling. The qualitative data were processed using thematic analysis. The MFAs included in this research were those used as sports or physical activity trackers, such as Apple Fitness, Strava, Nike Run Club, and Fita. The results of the data analysis show that 3 groups of incentives, namely, self-monitoring, platform rewards, and external influence (with the exception of social support), affect the perceived usefulness of these apps. Gender was also shown to moderate user behavior in relation to physical activity. The study showed that women were more likely to be motivated to exercise by social and external factors, while men paid greater attention to the tracking features of the app and to challenges and rewards. This research contributes to the field of health promotion by providing guidance for MFA developers.

INcentives and ReMINDers to Improve Long-Term Medication Adherence (INMIND): impact of a pilot randomized controlled trial in a large HIV clinic in Uganda.

Habits are a common strategy for successfully countering medication non-adherence, yet existing interventions do not support participants during the long habit formation period, resulting in high attrition. We test a novel intervention combining text messages and incentives with anchoring to support antiretroviral therapy (ART) pill-taking habits. In a randomized, parallel controlled trial, a sample of 155 participants 18 years and older who initiated ART within 3 months were recruited at Mildmay Uganda between October 2021 and April 2022. All participants were educated on the anchoring strategy and chose an anchor, that is existing routines, to pair with pill-taking. Participants were randomized to either usual care (C = 49), daily text message reminders to follow their anchoring plan (Messages group; T1 = 49) or messages and incentives conditional on pill-taking in line with their anchor (Incentives group; T2 = 57). Assessments occurred at baseline, month 3 (end of intervention) and month 9 (end of observation period). The primary outcomes are electronically measured mean adherence and pill-taking consistent with participants' anchor time. The primary outcome of pill-taking in line with the anchoring plan was higher in the Incentives group during the 3-month intervention (12.2 p.p. [95% CI: 2.2 22.2; p =.02]), and remained significantly higher after the incentives were withdrawn (months 4-6 (14.2 p.p. [95% CI 1.1 27.2; p =.03]); months 7-9 (14.1 p.p. [95% CI -0.2 28.5; p =.05])). Mean adherence was higher in both treatment groups relative to the control group during the intervention (T1 vs. C, p =.06; T2 vs. C, p =.06) but not post-intervention. The promising approach of using incentives to support habit formation among ART treatment initiators needs to be evaluated in a fully powered study to further our understanding of the habit formation process and to evaluate its cost-effectiveness.

Text Messages With Financial Incentives for Men With Obesity

Effective weight loss interventions are needed for men with obesity. To determine whether an intervention that combined text messaging with financial incentives attained significant weight loss at the 12-month follow-up compared with the control group and whether an intervention of text messaging alone attained significant weight loss at the 12-month follow-up compared with the control group. An assessor-blinded randomized clinical trial conducted in Belfast, Bristol, and Glasgow areas in the UK. A total of 585 men with body mass index (BMI) of 30 or more were enrolled between July 2021 and May 2022. Final follow-up occurred June 2023. Participants were randomly assigned to 12 months of behavioral focused text messages combined with financial incentives (n = 196), 12 months of behavioral focused text messages alone (n= 194), or a waiting list (control group; n= 195). The financial incentive consisted of a monetary reward that was lost if weight loss targets were not met. All participants received weight management information and a pedometer at baseline. The 2 primary comparisons were the 12-month comparison of within-participant weight change between the text messaging with financial incentive group and the control group and the comparison between the text messaging alone group and the control group (minimum clinically important difference, 3%). The P value defined for statistical significance was P < .025 for each comparison. Of the 585 men (mean [SD] age, 50.7 [13.3] years; mean weight, 118.5 [19.9] kg; mean BMI, 37.7 [5.7]; 525 [90%] White), 227 (39%) lived in postal code areas with lower socioeconomic status, and 426 (73%) completed the 12-month follow-up. At the 12-month follow-up, compared with the control group, the mean percent weight change was significantly greater in the text messaging with financial incentive group (mean difference, -3.2%; 97.5% CI, -4.6% to -1.9%; P < .001) but was not significantly greater in the text messaging alone group (mean difference, -1.4%; 97.5% CI, -2.9% to 0.0, P = .05). The mean (SD) weight changes were -5.7 (7.4) kg for the text messaging with financial incentives group, -3.0 (7.5) kg for the text messaging alone group, and -1.5 (6.6) kg for the control group. The 12-month mean (SD) percentage weight changes from baseline were -4.8% (6.1%) for the text messaging with financial incentives group, -2.7% (6.3%) for text messaging alone group, and -1.3% (5.5%) for the control group. Of 366 adverse events reported, the most common were infections (83 [23%]). Of the 23 serious adverse events (6.3%), 12 (52%) occurred in the text messaging with financial incentives group, 5 (22%) in the texts messaging alone group, and 6 (26%) in the control group. None were considered related to participating in a trial group. Among men with obesity, an intervention with text messaging with financial incentive significantly improved weight loss compared with a control group, whereas text messaging alone was not significantly better than the control condition. These findings support text messaging combined with financial incentives to attain weight loss in men with obesity. isrctn.org Identifier: ISRCTN91974895.

Research on the Relationship between Equity Incentive and Enterprise Performance Based on Propensity Score Matching

In corporate governance, the separation of ownership and management rights has always been a difficult problem for enterprises and academic circles. The introduction of equity incentive plan has alleviated the separation of the two rights to a certain extent. Ordinary OLS regression is difficult to overcome the influence of endogeneity. Therefore, the companies selected in this paper are Shanghai and Shenzhen A-share listed companies in China, and their financial data from 2010 to 2022 are selected for research, uses propensity score matching method to divide the samples into incentive group and control group, and conducts co-support test and balance test on the samples, so as to study the relationship between equity incentive and enterprise performance. Linear regression method is used to analyze the effect of government subsidies on firm performance. It is found that the implementation of equity incentive can improve the performance level of enterprises. Through the role of government subsidies, the influence of equity incentive on the performance level of enterprises will be enhanced.

TRENDS TOWARDS BUILDING A SYSTEM OF PERSONNEL INCENTIVES IN THE FIELD OF ADDITIONAL EDUCATION

The article voices the problems of multiple approaches to building a system of employee incentives from the positions of labor economics, psychology and management. An analysis of the content characteristics of the personnel incentives category used by the authors in the scientific literature is carried out, and in order to compile a holistic picture of the field of study, the categories of labor incentives and motivation are analyzed. Theoretical analysis revealed that there is no single approach to the interpretation of the concept of “stimulation”, which is often replaced by the category of “motivation” A list of factors that have a stimulating and motivating effect on work activity is proposed. The features of motivating incentives are highlighted in relation to the specifics of the activities of the organization of additional education. It was revealed that in order to stimulate personnel in the organization of additional education, increasing social status and seeing the prospects for personal development can serve as an element of motivation and should contribute to the development of professional competencies. The balance of coincidence of interests of the individual and the organization is included in the proposed concept of the mechanism for stimulating staff of the organization of additional education. A list of motivating factors for building a personnel incentive system was generated, and on its basis a study was conducted among 36 employees of an additional education organization. It was revealed that, along with traditional effective incentives (monetary remuneration based on work results, comfortable working conditions, benefits, gratitude, rewards, safety), it is important for employees of additional education organizations to feel involved in the employer and the opportunity for self-realization and self-development. As a study result, three groups of psychological, social and non-material incentives were proposed as the basis of a generalized model of stimulating staff of an additional education organization, based on the harmonization of the interests of the subjects of the study: the individual and the organization.

Increasing Vaccine Uptake Interventions: Lessons Learnt from South Asia

Background: Vaccinations are arguably the most effective tool for preventing infectious diseases and reducing mortality. Pakistan reports some of the highest numbers in the world for unvaccinated children. The low vaccine uptake is attributable to numerous factors, such as illiteracy, vaccine hesitancy, and lack of resources. Given these challenges, effective policymaking is crucial for improving uptake and reducing childhood mortality. This study aims to review the data on vaccine uptake interventions in South Asia and provide insight into their effectiveness and impactfulness in guiding future endeavors in the country. Objective: To assess various vaccine uptake interventions aimed at Pakistani and other South Asian communities. To compare their effects in terms of increased vaccine awareness and coverage and decrease in disease prevalence, especially of communicable diseases. Methodology: The study systematically assessed literature related to vaccine uptake interventions using the PubMed and Google Scholar electronic databases. Articles were systematically screened and checked for eligibility according to PRISMA guidelines. They were assessed for quality and risk of bias, and finally added to the review. Statistical analysis was performed for available data, odds ratio and % increase in outcome were calculated for interventions, and forest plot was plotted where possible. P-values were calculated to check for significance, and heterogeneity was assessed using chi-square, tau, and I² tests. Results: The search yielded a total of 434 results, and after screening and eligibility check, 14 remaining studies were included in the review. Interventions were classified as either educational, vaccine delivery based, incentive based, and reminder based interventions. 8 studies reported educational interventions. The highest vaccine coverage odds were reported for DPT-3 coverage (Andersson, 2009) as a result of Focused Group Discussion Intervention (OD 95% CI = 3.46 [2.62, 4.58] p&lt;0.0001) and BCG vaccine (Anjum, 2004) with House-to-House health messages (OD 95% CI = 3.10 [1.55, 6.19, p&lt;0.001), with more than three times odds of vaccination as compared to no intervention (Control). There were 4 studies in the Delivery-based intervention group and two each in incentive and reminder groups. Upon comparison, multifaceted interventions targeted at vaccine awareness and delivery show the greatest odds of increasing vaccine coverage. Conclusions: The current systematic review includes the first quantitative analysis of vaccine uptake interventions specific to the South-Asian population. The significance of multifaceted interventions targeting vaccine literacy and delivery is evident from the results and should be considered during state-level decision-making. Further research with better resources and broader scope should be conducted to gather critical evidence on the topic.

Financial incentives for reduced alcohol use and increased isoniazid adherence during tuberculosis preventive therapy among people with HIV in Uganda: an open-label, factorial randomised controlled trial

Alcohol use is common among people with HIV and is a risk factor for tuberculosis disease and non-adherence to isoniazid preventive therapy (IPT). Few interventions exist to reduce alcohol use and increase IPT adherence in sub-Saharan Africa. The aim of this study was to test the hypothesis that financial incentives conditional on point-of-care negative urine alcohol biomarker testing and positive urine isoniazid testing would reduce alcohol use and increase isoniazid adherence, respectively, in people with HIV who have latent tuberculosis infection and hazardous alcohol use. We conducted an open-label, 2×2 factorial randomised controlled trial in Uganda. Eligible for the study were non-pregnant HIV-positive adults (aged ≥18 years) prescribed antiretroviral therapy for at least 6 months, with current heavy alcohol use confirmed by urine ethyl glucuronide (biomarker of recent alcohol use) and a positive Alcohol Use Disorders Identification Test-Consumption (AUDIT-C; ≥3 for women, ≥4 for men) for the past 3 months' drinking, no history of active tuberculosis, tuberculosis treatment, or tuberculosis preventive therapy, and a positive tuberculin skin test. We randomly assigned participants (1:1:1:1) initiating 6 months of IPT to: no incentives (group 1); or incentives for recent alcohol abstinence (group 2), isoniazid adherence (group 3), or both (group 4). Escalating incentives were contingent on monthly point-of-care urine tests negative for ethyl glucuronide (groups 2 and 4), or positive on IsoScreen (biomarker of recent isoniazid use; groups 3 and 4). The primary alcohol outcome was non-hazardous use by self-report (AUDIT-C <3 for women, <4 for men) and phosphatidylethanol (PEth; past-month alcohol biomarker) <35 ng/mL at 3 months and 6 months. The primary isoniazid adherence outcome was more than 90% bottle opening of days prescribed. We performed intention-to-treat analyses. This trial is registered with ClinicalTrials.gov (NCT03492216), and is complete. From April 16, 2018, to Aug 2, 2021, 5508 people were screened, of whom 680 were randomly assigned: 169 to group 1, 169 to group 2, 170 to group 3, and 172 to group 4. The median age of participants was 39 years (IQR 32-47), 470 (69%) were male, 598 (90%) of 663 had HIV RNA viral loads of less than 40 copies per mL, median AUDIT-C score was 6 (IQR 4-8), and median PEth was 252 ng/mL (IQR 87-579). Among 636 participants who completed the trial with alcohol use endpoint measures (group 1: 152, group 2: 159, group 3: 161, group 4: 164), non-hazardous alcohol use was more likely in the groups with incentives for alcohol abstinence (groups 2 and 4) versus no alcohol incentives (groups 1 and 3): 57 (17·6%) of 323 versus 31 (9·9%) of 313, respectively; adjusted risk difference (aRD) 7·6% (95% CI 2·7 to 12·5, p=0·0025). Among 656 participants who completed the trial with isoniazid adherence endpoint measures (group 1: 158, group 2: 163, group 3: 168, group 4: 167), incentives for isoniazid adherence did not increase adherence: 244 (72·8%) of 335 in the isoniazid incentive groups (groups 3 and 4) versus 234 (72·9%) of 321 in the no isoniazid incentive groups (groups 1 and 2); aRD -0·2% (95% CI -7·0 to 6·5, p=0·94). Overall, 53 (8%) of 680 participants discontinued isoniazid due to grade 3 or higher adverse events. There was no significant association between randomisation group and hepatotoxicity resulting in isoniazid discontinuation, after adjusting for sex and site. Escalating financial incentives contingent on recent alcohol abstinence led to significantly lower biomarker-confirmed alcohol use versus control, but incentives for recent isoniazid adherence did not lead to changes in adherence. The alcohol intervention was efficacious despite less intensive frequency of incentives and clinic visits than traditional programmes for substance use, suggesting that pragmatic modifications of contingency management for resource-limited settings can have efficacy and that further evaluation of implementation is merited.

Conditional versus non-conditional incentives to maximise return of participant completed questionnaires in clinical trials: a cluster randomised study within a trial

BackgroundHigh participant retention enhances the validity of clinical trials. A monetary incentive can increase retention, but it is not known if when it is provided and if it is conditional matters. We aimed to determine whether there was a difference in the number of follow-up trial questionnaires returned when a monetary (gift voucher) incentive was given to participants at recruitment (non-conditional), compared to informing participants at recruitment that the incentive would be given only once their 14-day daily diary (questionnaire) had been returned (conditional).MethodA cluster randomised study within a trial embedded within the Antivirals for influenza-Like Illness, An rCt of Clinical and Cost effectiveness in primary CarE (ALIC4E) Trial. Matched site pairs (GP practices) were randomised using computer-generated random numbers, to either a non-conditional or conditional monetary voucher incentive (only once their 14-day daily diary (questionnaire) had been returned. Sites were matched on previous recruitment levels and practice list size. Analyses were conducted according to randomised groups irrespective of compliance with a two-sided 5% level statistical significance level. The main analysis of the primary outcome (site proportion of diaries returned) was linear regression accounting for site pair (using cluster-robust variance). Additional weighted, paired and non-parametric sensitivity analyses were conducted. Secondary outcomes were the site average number of completed pages, time to return diary, and cost related to the incentive (administration and postage).ResultsOf the 42 randomised sites (21 for each intervention), only 28 recruited at least one participant with only 10 practice pairs recruiting participants at both constituent sites. Raw diaries return proportions were 0.58 (127/220) and 0.73 (91/125) for non-conditional and conditional incentive groups. Regression analysis adjusted for site pair showed no significant difference in returns, − 0.09, (95% CI, − 0.29, 0.10, p = 0.34); when weighted, there was still no clear difference: 0.15 (95% CI, − 0.02, 0.31, p = 0.07). There was no clear statistical evidence of a difference in time taken to return questionnaires, nor the proportion of pages completed, by the intervention group in the main analyses (all p > 0.05). The conditional incentive was approximately £23 cheaper per diary returned based upon observed data.ConclusionThere was no clear evidence of a statistically significant difference in the proportion of participant-completed diaries returned between conditional or non-conditional incentive groups. The time to questionnaire return and completeness of the returned questionnaires were similar in both groups. There was substantial statistical uncertainty in the findings. Some of the sensitivity analyses suggested that a meaningful benefit of a conditional incentive of a magnitude that would be meaningful was plausible. The conditional approach costs less in cash terms.

The effect of loss incentives on prospective memory in healthy older adults: study protocol of a randomized controlled trial using ultra-high field fMRI

BackgroundProspective memory is important for our health and independence but declines with age. Hence, interventions to enhance prospective memory, for example by providing an incentive, may promote healthy ageing. The neuroanatomical correlates of prospective memory and the processing of incentive-related prospective memory changes in older adults are not fully understood. In an fMRI study, we will therefore test whether incentives improve prospective memory in older adults and how prospective memory is processed in the brain in general, and when incentives are provided. Since goals and interests change across adulthood, avoiding losses is becoming more important for older adults than achieving gains. We therefore posit that loss-related incentives will enhance prospective memory, which will be subserved by increased prefrontal and midbrain activity.MethodsWe will include n = 60 healthy older adults (60–75 years of age) in a randomized, single-blind, and parallel-group study. We will acquire 7T fMRI data in an incentive group and a control group (n = 30 each, stratified by education, age, and sex). Before and after fMRI, all participants will complete questionnaires and cognitive tests to assess possible confounders (e.g., income, personality traits, sensitivity to reward or punishment).DiscussionThe results of this study will clarify whether loss-related incentives can enhance prospective memory and how any enhancement is processed in the brain. In addition, we will determine how prospective memory is processed in the brain in general. The results of our study will be an important step towards a better understanding of how prospective memory changes when we get older and for developing interventions to counteract cognitive decline.

Evaluation of an organisational-level monetary incentive to promote the health and wellbeing of workers in small and medium-sized enterprises: A mixed-methods cluster randomised controlled trial.

We conducted an independent evaluation on the effectiveness of an organisational-level monetary incentive to encourage small and medium-sized enterprises (SMEs) to improve employees' health and wellbeing. This was A mixed-methods cluster randomised trial with four arms: high monetary incentive, low monetary incentive, and two no monetary incentive controls (with or without baseline measurements to examine 'reactivity' The consequence of particpant awareness of being studied, and potential impact on participant behavior effects). SMEs with 10-250 staff based in West Midlands, England were eligible. We randomly selected up to 15 employees at baseline and 11 months post-intervention. We elicited employee perceptions of employers' actions to improve health and wellbeing; and employees' self-reported health behaviours and wellbeing. We also interviewed employers and obtained qualitative data. One hundred and fifty-two SMEs were recruited. Baseline assessments were conducted in 85 SMEs in three arms, and endline assessments in 100 SMEs across all four arms. The percentage of employees perceiving "positive action" by their employer increased after intervention (5 percentage points, pp [95% Credible Interval -3, 21] and 3pp [-9, 17], in models for high and low incentive groups). Across six secondary questions about specific issues the results were strongly and consistently positive, especially for the high incentive. This was consistent with qualitative data and quantitative employer interviews. However, there was no evidence of any impact on employee health behaviour or wellbeing outcomes, nor evidence of 'reactivity'. An organisational intervention (a monetary incentive) changed employee perceptions of employer behaviour but did not translate into changes in employees' self-reports of their own health behaviours or wellbeing. Trial registration: AEARCTR-0003420, registration date: 17.10.2018, retrospectively registered (delays in contracts and identfying a suitable trial registry). The authors confirm that there are no ongoing and related trials for this intervention.

Effects of repetition as training and incentives on the performance in pulmonary function tests in healthy volunteers

Pulmonary function testing (PFT) is a central part of diagnosis and treatment monitoring in respiratory medicine. Few studies have investigated whether repeated PFT or training can significantly influence performance.To investigate potential training effects of repeated PFT, 30 healthy volunteers underwent daily and weekly repeated PFT with spirometry over 10 weeks. The study included 22 females and 8 males with a mean age of 31.8 years ± 15 (SD), a mean weight of 66.3 kg ± 14.5 (SD) and a mean BMI of 22.4 ± 3.3 (SD). The first 5 PFTs were performed on 5 consecutive days, followed by 3 PFTs once a week on the same day of the week. Subsequently, 5 measurements were taken daily for 5 consecutive days. After these 13 appointments in 5 weeks, participants were randomly assigned to the control or incentive group, with stratification for age and gender. The incentive group had the opportunity to win money (200 €) for the highest increase in forced vital capacity (FVC). PFTs were performed once a week on the same day of the week as before for 5 more times. Motivation was assessed by a questionnaire before the 1st, 9th and 18th measure of PFT at three time points throughout the study.An increase in PFT was observed with mean increases of 473 [ml] in FVC, 395 [ml] in forced expiratory volume in 1 s (FEV1) and 1.382 [litres/second] in peak expiratory flow (PEF) after four days of daily PFT. These increases did not persist and spirometric data returned to baseline after one week. After allocation, participants in the incentive group did not increase their FVC, FEV1 or PEF compared to the control group. The incentive group showed higher motivation than the control group, even before allocation.Repeated daily PFT could induce short-term increases, but PFT does not fluctuate significantly in the long term. External influences that affect motivation could not consistently increase PFT. For clinical practice, it can be concluded that PFT does not necessarily require extended training to ensure reliability if reproducibility criteria are met.

Assessing the sustainable incentive on worker performances as a means of conquering new frontiers in Enugu state, Nigeria

Incentive is one of the motivational approach, which has an energizing force that induces or compels and maintain performance of every worker. Thus, it will be of important if the impact of standardized and sustainable incentives is implied to every worker in construction industry. The aim of the paper is to assess the sustainable incentive on worker performances by assessing the relative significance index score for different types of incentives; and identifying the average level of impact for the three groups of incentives for workers’ performances. The targeted population of this study were contractors, architects, quantity surveyors, engineers in Enugu state. Data collection was done through a questionnaire survey self-administered on 80 randomly selected construction professionals involved in a nearly completed or recently completed construction projects. This was analyzed using descriptive statistics and analyses of variance (ANOVA). Results of the study indicate a disparity of the ranking of the degree of occurrence and impact among the group. Based on the composite of incentive factors the study established its likelihood of various occurrence of both financial and non-financial incentives. The study recommended that those with highly impacted incentives should be put in place in which it will become a means of conquering the new frontier with a solid sustenance. Finally, the study also concluded that they should implement an efficient, standardized and effective of the three groups of the incentives on workers in order to gear toward fully sustainable commitment, solid participation and loyal performances.

Effects of Mobile-Based Financial Incentive Interventions for Adults at Risk of Developing Hypertension: Feasibility Randomized Controlled Trial.

Hypertension is the leading modifiable risk factor for cardiovascular disease and mortality. Adopting lifestyle modifications, like increasing physical activity (PA), can be an effective strategy in blood pressure (BP) control, but many adults do not meet the PA guidelines. Financial incentive interventions have the power to increase PA levels but are often limited due to cost. Further, mobile health technologies can make these programs more scalable. There is a gap in the literature about the most feasible and effective financial incentive PA framework; thus, pay-per-minute (PPM) and self-funded investment incentive (SFII) frameworks were explored. The aims were to (1) determine the feasibility (recruitment, engagement, and acceptability) of an 8-week mobile-based PPM and SFII hypertension prevention PA program and (2) explore the effects of PPM and SFII interventions relative to a control on the PA levels, BP, and PA motivation. In total, 55 adults aged 40-65 years not meeting the Canadian PA guidelines were recruited from Facebook and randomized into the following groups: financial incentive groups, PPM or SFII, receiving up to CAD $20 each (at the time of writing: CAD $1=US $0.74), or a control group without financial incentive. PPM participants received CAD $0.02 for each minute of moderate-to-vigorous PA (MVPA) per week up to the PA guidelines and the SFII received CAD $2.50 for each week they met the PA guidelines. Feasibility outcome measures (recruitment, engagement, and acceptability) were assessed. Secondary outcomes included changes in PA outcomes (MVPA and daily steps) relative to baseline were compared among PPM, SFII, and control groups at 4 and 8 weeks using linear regressions. Changes in BP and relative autonomy index relative to baseline were compared among the groups at follow-up. Participants were randomized to the PPM (n=19), SFII (n=18), or control (n=18) groups. The recruitment, retention rate, and engagement were 77%, 75%, and 65%, respectively. The intervention received overall positive feedback, with 90% of comments praising the intervention structure, financial incentive, and educational materials. Relative to the control at 4 weeks, the PPM and SFII arms increased their MVPA with medium effect (PPM vs control: η2p=0.06, mean 117.8, SD 514 minutes; SFII vs control: η2p=0.08, mean 145.3, SD 616 minutes). At 8 weeks, PPM maintained a small effect in MVPA relative to the control (η2p=0.01, mean 22.8, SD 249 minutes) and SFII displayed a medium effect size (η2p=0.07, mean 113.8, SD 256 minutes). Small effects were observed for PPM and SFII relative to the control for systolic blood pressure (SBP) and diastolic blood pressure (DBP) (PPM: η2p=0.12, Δmean SBP 7.1, SD 23.61 mm Hg; η2p=0.04, Δmean DBP 3.5, SD 6.2 mm Hg; SFII: η2p=0.01, Δmean SBP -0.4, SD 1.4 mm Hg; η2p=0.02, Δmean DBP -2.3, SD 7.7 mm Hg) and relative autonomy index (PPM: η2p=0.01; SFII: η2p=0.03). The feasibility metrics and preliminary findings suggest that a future full-scale randomized controlled trial examining the efficacy of PPM and SFII relative to a control is feasible, and studies with longer duration are warranted.

Bupropion Slow Release vs Placebo With Adaptive Incentives for Cocaine Use Disorder in Persons Receiving Methadone for Opioid Use Disorder

Opioid-stimulant co-use is a common problem with few evidence-based treatments. To examine bupropion slow release (SR) enhancement of a tailored abstinence incentive program for stimulant use in persons with opioid use disorder. This 26-week, double-blind, placebo-controlled randomized clinical trial with a 4-week follow-up period was conducted at 4 methadone treatment programs in Baltimore, Maryland. Included participants were persons receiving methadone for the treatment of opioid use disorder with past 3-month cocaine use and current cocaine use disorder between March 2015 and September 2019. Data were analyzed from November 2020 through August 2022. A 6-week incentive induction period with monetary incentives for evidence of cocaine abstinence during thrice-weekly urine testing was conducted. Persons achieving 2 weeks of consecutive abstinence during induction were assigned to the relapse prevention group (20 individuals); otherwise, individuals were assigned to the abstinence initiation group (60 individuals). Participants were randomized within incentive groups to bupropion SR (150 mg oral twice daily; 40 participants) or placebo (40 participants). Incentives were available until week 26, and study medication ended week 30. The mean percentage of participants with cocaine abstinence (by negative urinalysis or self-report) during weeks 7 to 26 (ie, the incentive intervention period) and 27 to 30 (ie, the follow-up period) and the percentage of participants testing negative for cocaine at weeks 26 and 30 were assessed. Main effects of medication collapsed across incentive conditions and sensitivity analyses of medications within incentive conditions were assessed. Analyses were conducted in the modified intention-to-treat sample (ie, 80 individuals who received ≥1 dose of study medication) and completers (ie, 52 individuals who completed ≥1 visit during week 30). Among 80 participants (42 Black [52.5% ] and 35 White [43.8%]; mean [SD] age, 45.7 (9.4) years; 52 males [65.0%]) receiving methadone for opioid use disorder, 40 participants were randomized to receive bupropion SR and 40 participants to receive placebo. No significant difference on urinalysis or self-reported cocaine use was observed between medication groups. Sensitivity analyses revealed differential patterns for incentive subgroups. Participants in the relapse prevention group had high abstinence (>80%; eg, during weeks 7-26 in the modified intention-to-treat analysis, 410 of 456 samples [89.9%] from participants in the bupropion SR group tested negative for cocaine) throughout the trial regardless of whether they were randomized to bupropion SR or placebo. Participants in the abstinence initiation group had better outcomes with bupropion SR than placebo throughout the trial (mean [SD] total number of samples testing negative for cocaine, 30.3 [21.6] samples for bupropion SR vs 17.1 [14.9] samples for placebo; P = .05) and more participants receiving bupropion SR than placebo were abstinent at the end of the study (20 of 30 participants [66.7%] vs 9 of 30 participants [30.0%]; P = .04). In this randomized clinical trial, an overall benefit for bupropion SR vs placebo when combined with a financial abstinence incentive program was not observed. Results among incentive subgroups suggest that continued evaluation of medications, including bupropion SR, for stimulant treatment using a tailored approach that factors early abstinence into study design and interpretation may be needed.
