A Large-Scale Replication of the Effectiveness of the KiVa Antibullying Program: a Randomized Controlled Trial in the Netherlands.

ABSTRACT: This study evaluates the effectiveness of the KiVa antibullying program in the Netherlands through a randomized controlled trial of students in grades 3-4 (Dutch grades 5-6). The sample involved 98 schools who volunteered to participate in the research, with 245 classes and 4383 students at the baseline (49% girls; M age?=?8.7 years), who participated in five measurement waves, collected in three consecutive school years. After the baseline, two-thirds of the schools were assigned to the intervention condition (KiVa or KiVa+, the latter included an additional intervention component of network feedback to teachers) and one-third to the control condition (waiting list, care as usual) with a stratified randomization procedure. The effects of the intervention on self-reported victimization and bullying were tested using cross-classified ordered multinomial models and binomial logistic regression models. These longitudinal models showed that self-reported victimization and bullying reduced more strongly in KiVa-schools compared with control schools, with stronger effects after two school years than after one school year of implementation. The results showed that for students in control schools, the odds of being a victim were 1.29-1.63 higher, and the odds of being a bully were 1.19-1.66 higher than for KiVa students. No significant differences between KiVa and KiVa+ emerged. Overall, the findings provide evidence of the effectiveness of the KiVa program in the Netherlands.

Project description:IntroductionLifestyle Triple P is a general parenting intervention which focuses on preventing further excessive weight gain in overweight and obese children. The objective of the current study was to assess the effectiveness of the Lifestyle Triple P intervention in the Netherlands.MethodWe used a parallel randomized controlled design to test the effectiveness of the intervention. In total, 86 child-parent triads (children 4-8 years old, overweight or obese) were recruited and randomly assigned (allocation ratio 1:1) to the Lifestyle Triple P intervention or the control condition. Parents in the intervention condition received a 14-week intervention consisting of ten 90-minute group sessions and four individual telephone sessions. Primary outcome measure was the children's body composition (BMI z-scores, waist circumference and skinfolds). The research assistant who performed the measurements was blinded for group assignment. Secondary outcome measures were the children's dietary behavior and physical activity level, parenting practices, parental feeding style, parenting style, and parental self-efficacy. Outcome measures were assessed at baseline and 4 months (short-term) and 12 months (long-term) after baseline. Multilevel multiple regression analyses were conducted to determine the effect of the intervention on primary and secondary outcome measures.ResultsNo intervention effects were found on children's body composition. Analyses of secondary outcomes showed positive short-term intervention effects on children's soft-drink consumption and parental responsibility regarding physical activity, encouragement to eat, psychological control, and efficacy and satisfaction with parenting. Longer-term intervention effects were found on parent's report of children's time spent on sedentary behavior and playing outside, parental monitoring food intake, and responsibility regarding nutrition.ConclusionAlthough the Lifestyle Triple P intervention showed positive effects on some parent reported child behaviors and parenting measures, no effects were visible on children's body composition or objectively measured physical activity. Several adjustments of the intervention content are recommended, for example including a booster session.Trial registrationNederlands Trial Register NTR 2555.

Project description:Bullying is a major problem worldwide and Chile is no exception. Bullying is defined as a systematic aggressive behavior against a victim who cannot defend him or herself. Victims suffer social isolation and psychological maladjustment, while bullies have a higher risk for conduct problems and substance use disorders. These problems appear to last over time. The KiVa antibullying program has been evaluated in Finland and other European countries, showing preventive effects on victimization and self-reported bullying. The aims of this study are (1) to develop a culturally appropriate version of the KiVa material and (2) to test the effectiveness of the KiVa program, with and without the online game, on reducing experiences of victimization and bullying behavior among vulnerable primary schools in Santiago (Chile), using a cluster randomized controlled trial (RCT) design with three arms: (1) full KiVa program group, (2) partial KiVa (without online game) program group and (3) control group.This is a three-arm, single-blind, cluster randomized controlled trial (RCT) with a target enrolment of 1495 4th and 5th graders attending 13 vulnerable schools per arm. Students in the full and partial KiVa groups will receive universal actions: ten 2-h lessons delivered by trained teachers during 1 year; they will be exposed to posters encouraging them to support victims and behave constructively when witnessing bullying; and a person designated by the school authorities will be present in all school breaks and lunchtimes using a visible KiVa vest to remind everybody that they are in a KiVa school. KiVa schools also will have indicated actions, which consist of a set of discussion groups with the victims and with the bullies, with proper follow-up. Only full KiVa schools will also receive an online game which has the aim to raise awareness of the role of the group in bullying, increase empathy and promote strategies to support victimized peers. Self-reported victimization, bullying others and peer-reported bullying actions, psychological and academic functioning, and sense of school membership will be measured at baseline and 12 months after randomization.This is the first cluster RCT of the KiVa antibullying program in Latin America.ClinicalTrials.gov, Identifier: NCT02898324 .

Project description:BackgroundThough the Rwandan Ministry of Health (MOH) prioritizes the scale-up of postpartum family planning (PPFP) programs, uptake and sustainability of PPFP services in Rwanda are low. Furthermore, highly effective long-acting reversible contraceptive method use (LARC), key in effective PPFP programs, is specifically low in Rwanda. We previously pilot tested a supply-demand intervention which significantly increased the use of postpartum LARC (PPLARC) in Rwandan government clinics. In this protocol, we use an implementation science framework to test whether our intervention is adaptable to large-scale implementation, cost-effective, and sustainable.MethodsIn a type 2 effectiveness-implementation hybrid study, we will evaluate the impact of our PPFP intervention on postpartum LARC (PPLARC) uptake in a clinic-randomized trial in 12 high-volume health facilities in Kigali, Rwanda. We will evaluate this hybrid study using the RE-AIM framework. The independent effectiveness of each PPFP demand creation strategy on PPLARC uptake among antenatal clinic attendees who later deliver in a study facility will be estimated. To assess sustainability, we will assess the intervention adoption, implementation, and maintenance. Finally, we will evaluate intervention cost-effectiveness and develop a national costed implementation plan.DiscussionAdaptability and sustainability within government facilities are critical aspects of our proposal, and the MOH and other local stakeholders will be engaged from the outset. We expect to deliver PPFP counseling to over 21,000 women/couples during the project period. We hypothesize that the intervention will significantly increase the number of stakeholders engaged, PPFP providers and promoters trained, couples/clients receiving information about PPFP, and PPLARC uptake comparing intervention versus standard of care. We expect PPFP client satisfaction will be high. Finally, we also hypothesize that the intervention will be cost-saving relative to the standard of care. This intervention could dramatically reduce unintended pregnancy and abortion, as well as improve maternal and newborn health. Our PPFP implementation model is designed to be replicable and expandable to other countries in the region which similarly have a high unmet need for PPFP.Trial registrationClinicalTrials.gov NCT05056545 .

Project description:BACKGROUND:The content of online computer-tailored interventions is often determined to match an individual's characteristics, beliefs, and behavioral factors. These content-tailored interventions lead to better message processing and a higher likelihood of behavior change such as smoking cessation. However, a meta-analysis of online computer-tailored interventions showed that effect sizes, albeit positive, remain small, suggesting room for improvement. A promising strategy to enhance the effectiveness of online computer-tailored interventions is to tailor the message frame (ie, how a message is communicated) based on the preferred communication style of the user in addition to content-tailoring. One factor that determines an individual's communication style preference is the need for autonomy; some individuals prefer an autonomy-supportive communication style (offering choice and use of suggestive language), whereas others might prefer a directive communication style, which is replete with imperatives and does not provide choice. Tailoring how messages are presented (eg, based on the need for autonomy) is called message frame-tailoring. OBJECTIVE:The aim of the present study was to test the effectiveness of message frame-tailoring based on the need for autonomy, in isolation and in combination with content-tailoring, within the context of an online computer-tailored smoking cessation intervention. The primary outcome measure was the 7-day point-prevalence of smoking abstinence. Secondary outcomes were perceived message relevance, self-determined motivation to quit smoking, and sociocognitive beliefs. METHODS:A randomized controlled trial with a 2 (message frame-tailoring vs no message frame-tailoring) by 2 (content-tailoring vs no content-tailoring) design was conducted among adult smokers intending to quit smoking (N=273). RESULTS:Structural equation modeling revealed that the content-tailored condition increased smoking abstinence rates 1 month after the start of the intervention (beta=.57, P=.02). However, neither message frame-tailoring nor its interaction with content-tailoring significantly predicted smoking abstinence. In our model, message frame-tailoring, content-tailoring, as well as their interaction significantly predicted perceived relevance of the smoking cessation messages, which consequently predicted self-determined motivation. In turn, self-determined motivation positively affected attitudes and self-efficacy for smoking cessation, but only self-efficacy consequently predicted smoking abstinence. Participants in the control condition perceived the highest level of message relevance (mean 4.78, SD 1.27). However, messages that were frame-tailored for individuals with a high need for autonomy in combination with content-tailored messages led to significantly higher levels of perceived message relevance (mean 4.83, SD 1.03) compared to those receiving content-tailored messages only (mean 4.24, SD 1.05, P=.003). CONCLUSIONS:Message frame-tailoring based on the need for autonomy seems to be an effective addition to conventional content-tailoring techniques in online smoking cessation interventions for people with a high need for autonomy; however, this is not effective in its current form for people with a low need for autonomy.

Project description:BACKGROUND: Intensive lifestyle intervention significantly reduces the progression to diabetes in high-risk individuals. OBJECTIVE: It is not known whether a program of moderate intervention might effectively reduce metabolic abnormalities in the general population. DESIGN: Two-arm randomized controlled 1-year trial. PATIENTS: Three hundred and thirty-five patients participated from a dysmetabolic population-based cohort of 375 adults aged 45-64 years in northwestern Italy. MEASUREMENTS: We compared the effectiveness of a general recommendation-based program of lifestyle intervention carried out by trained professionals versus standard unstructured information given by family physicians at reducing the prevalence of multiple metabolic and inflammatory abnormalities. RESULTS: At baseline, clinical/anthropometric/laboratory and lifestyle characteristics of the intervention (n = 169) and control (n = 166) groups were not significantly different. The former significantly reduced total/saturated fat intake and increased polyunsaturated fat/fiber intake and exercise level compared to the controls. Weight, waist circumference, high-sensitivity C-reactive protein, and most of the metabolic syndrome components decreased in the intervention group and increased in the controls after 12 months. Lifestyle intervention significantly reduced metabolic syndrome (odds ratio [OR] = 0.28; 95% CI 0.18-0.44), with a 31% (21-41) absolute risk reduction, corresponding to 3.2 (2-5) patients needing to be treated to prevent 1 case after 12 months. The intervention significantly reduced the prevalence of central obesity (OR = 0.33; 0.20-0.56), and hypertriglyceridemia (OR = 0.48; 0.31-0.75) and the incidence of diabetes (OR = 0.23; 0.06-0.85). CONCLUSION: A lifestyle intervention based on general recommendations was effective in reducing multiple metabolic/inflammatory abnormalities. The usual care by family physicians was ineffective at modifying progressive metabolic deterioration in high-risk individuals.
