Classroom-based interdependent group contingencies increase children's physical activity

Pilot study testing the effects of a multicomponent intervention for increasing moderate-intensity physical exercise

Physical inactivity has been associated with several health problems, including diabetes, obesity, and heart disease. Although many of these health problems are preventable through regular exercise, a small percentage of the adult population engages in the recommended levels. Reinforcement-based interventions have been implemented successfully to promote physical activity, but studies targeting moderate or vigorous physical exercise using behavior-analytic interventions are scarce. The purpose of the current study was to investigate the feasibility of a multicomponent intervention that provided monetary incentives for increasing running, jogging, or brisk walking distance for five adults. The intervention lasted 6 weeks and comprised weekly goal setting, feedback, public posting, and group contingencies. The results of the study suggest that the intervention may be feasible and effective at increasing moderate physical activity to levels recommended by the federal guidelines, but further research is warranted.

Using a group game increases preschoolers' step count

Children should engage in at least 60 min of physical activity daily to develop or maintain healthy habits (Centers for Disease Control and Prevention, 2021a). Previous research suggests that contingent attention is a powerful tool for increasing moderate to vigorous physical activity. In this study, the researchers examined the effects of a group game on steps per minute at recess in an inclusive classroom with preschoolers. The researcher taught the game called the T-Rex game in which the game rules (chasing students who were moving) involved contingencies for natural attention to follow moderate to vigorous physical activity. The results showed a functional relation between step count and the group game in which students engaged in higher step counts when the group game was in place than during baseline. These findings extend other work by demonstrating that contingent attention embedded in group games can increase step count.

Differential Reinforcement of Low Frequency Behavior as an Interdependent Group Contingency for Children Diagnosed with Autism Spectrum Disorder

An ABAB reversal design was employed to evaluate the effect of differential reinforcement of low (DRL) frequency behavior as an interdependent group contingency on the frequency of vocal disruptions of five males, 6-14-years old, diagnosed with an autism spectrum disorder. The results showed lower frequencies of vocal disruptions during intervention conditions as compared to baseline conditions; the combination of DRL and interdependent group contingency was effective at reducing the target behavior from baseline levels. Implications of concurrent interventions for the applied setting are discussed.

Goal Setting with Latinx Families of Children with Intellectual and Developmental Disabilities: Case Studies

Behavioral community psychology focuses on studying issues that matter to communities, unpacking contextual factors that impact people's behaviors, and identifying strategies to address such issues. Goal setting is one such strategy often used by behavioral psychologists. Grounded in the values of behavioral community psychology and a behavior analysis paradigm, this study illustrated two case studies of Latinx parents of children with disabilities where goal-setting strategies were implemented to promote behavior change. The first case study focused on the promotion of healthy lifestyle behaviors and routines among Latinx families of children with disabilities in the United States. The second case study examined goal setting related to youth development by parents of adolescents with disabilities in Colombia. In both cases, participants received training on goal setting and had opportunities to discuss progress toward achieving their goals, share action steps taken, and discuss the contextual challenges or barriers that they experienced. The results indicate that behavioral goal-setting procedures can be effective in helping parents attain their goals and brainstorm strategies for addressing behavioral and contextual challenges. Implications for future research advancing behavioral community psychology are discussed.

Effect of Group Contingency Type on Walking: Comparisons of Effectiveness and Cost Efficiency

Group contingency (GC) is an effective and cost-efficient strategy that can be successfully applied to technology-based interventions. This study examined the relative effectiveness and cost efficiency of three types of technology-based group contingencies on walking among adults. Seventy two students were divided into teams of three. Each team was randomly assigned to one of three GC conditions (independent, interdependent, or dependent) and underwent 66 days of technology-based group contingency intervention. Sixty five participants completed the intervention and 61 completed the follow-up assessment 2 months later. Step counts and self-reported walking activity increased after the intervention under all three conditions. The proportion of participants that met the target step counts was significantly higher under the dependent group contingency condition. However, 2 months later, intervention effects were not maintained under any condition. For cost efficiency, the increase in step count per point was significantly higher under the interdependent group contingency condition. Group cohesion and social validity (point satisfaction and point utility) were significantly higher under the dependent group contingency condition. Finally, the clinical implications and limitations of this study are discussed.

The Use of Self-Monitoring and Technology to Increase Physical Activity: A Review of the Literature

The current obesity epidemic and inactive lifestyles of many Americans lead to health problems for millions of Americans and in turn, millions of dollars in medical bills. One aspect of this problem is the lack of physical activity that people engage in. Self-monitoring techniques have been used in the past to increase physical activity. However, there has not been a systematic review of the literature on this research to date. Furthermore, as technology that is user-friendly and assists in self-monitoring physical activity becomes more available to the public, it is important to investigate its use when used in conjunction with self-monitoring. The purpose of this review was to determine how self-monitoring techniques and technology have been applied to increase physical activity across multiple populations. A systematic review of the literature identified 19 articles. Results indicated that the majority of studies used more than one type of self-monitoring intervention. The most popular type of technology used with self-monitoring were fitness trackers. Future research should continue to examine the most effective methodologies that produce lasting behavior change in physical activity.

Effects of Daily and Reduced Frequency Implementation of the Good Behavior Game in Kindergarten Classrooms

An effective group contingency, the Good Behavior Game (GBG), has been implemented successfully with a wide range of age groups. However, improvements in student behavior are often not observed when the GBG is abruptly terminated, and research has yet to evaluate the effects of the GBG when the frequency of implementation is reduced. The purpose of the current study was to evaluate the effect of the GBG, implemented daily initially then on a less frequent schedule. The study utilized a multiple baseline design across three kindergarten classrooms to evaluate the effectiveness and maintenance of the GBG at reducing classwide and target student disruptive behavior (DB) and increasing classwide and target student academic engagement. Reduced Frequency data were collected while withholding implementation of the GBG. The results indicate that the GBG was highly effective in improving classwide behavior, which was maintained throughout the final Reduced Frequency phase in which the GBG was reduced in frequency, and moderately effective in improving target student behavior during both phases.

Data presentation options to manage variability in physical activity research

This paper presents seven tactics for managing the variability evident in some physical activity data. High levels of variability in daily step-count data from pedometers or accelerometers can make typical visual inspection difficult. Therefore, the purpose of the current paper is to discuss several strategies that might facilitate the visual interpretation of highly variable data. The seven strategies discussed in this paper are phase mean and median lines, daily average per week, weekly cumulative, proportion of baseline, 7-day moving average, change point detection, and confidence intervals. We apply each strategy to a data set and discuss the advantages and disadvantages.
