Aligning Organizational Priorities and System Policies to Support Implementation Scale-Up of a Tailored Classroom-Based Physical Activity Intervention in Low-Resource Schools

BACKGROUND

A mismatch between organizational priorities and system-level policies can negatively impact implementation and sustainment of classroom-based physical activity (PA) interventions. The purpose of this study was twofold: (1) present methods to systematically identify organization- and system-level implementation barriers, and (2) align organizational priorities and system policies by designing multi-level implementation strategies. This alignment will support implementation scale-up of a tailored PA intervention in one low-resource intermediate school district (ISD; 16 districts, 32 schools) in central Michigan.

METHODS

Multi-level assessments of organizational readiness were conducted using the Hexagon Discussion and Analysis Tool to assess intervention-context fit, the Wellness School Assessment Tool 3.0 to evaluate district PA policy strength and comprehensiveness, and semi-structured interviews were conducted to assess administrative support and priorities related to PA programming.

RESULTS

Our assessments revealed three implementation barriers: limited structural capacity to sustain teacher training, limited resources across districts and school buildings to support teachers, and misalignment of ISD and district PA policies and priorities.

CONCLUSIONS

Greater attention to organizational capacity and existing infrastructure should be considered a priori to support effective implementation and sustainment of PA interventions in low-resource schools.

A Novel Policy Alignment and Enhancement Process to Improve Sustainment of School-Based Physical Activity Programming

The purpose of the current study was twofold: (1) to evaluate the strength and comprehensiveness of district wellness policies in one central Michigan intermediate school district (ISD; 16 districts), and (2) to pilot a novel policy alignment and enhancement process in one district within the ISD to improve sustainment of district-wide physical activity (PA) programming. Policy evaluation and alignment were determined using WellSAT 3.0. The Exploration, Preparation, Implementation, Sustainment (EPIS) framework was used to guide a seven-step policy alignment and enhancement process. Initial evaluation of the PA policy for the ISD revealed a strength score of 19/100 (i.e., included weak and non-specific language) and 31/100 for comprehensiveness (i.e., mentioned few components of the Comprehensive School Physical Activity Program). For the pilot school district, initial strength scores were 19/100 and 38/100 for comprehensiveness (exploration). An alignment of the tailored PA policy with current practices resulted in a 100% increase in strength (score of 38/100), and 132% increase in comprehensiveness (score of 88/100; preparation). However, district administrators encountered barriers to adopting the tailored policy and subsequently integrated the PA requirements into their curriculum guide and school improvement plan (implementation and sustainment). Future research should examine the effectiveness of our EPIS-informed policy evaluation, alignment, and enhancement process to promote widespread increases in student PA.

Rapid cycle adaptation of a classroom-based intervention to promote equity in access to youth physical activity

Our objective was to systematically adapt Interrupting Prolonged sitting with ACTivity (InPACT), a classroom-based physical activity intervention, for home delivery to equitably increase access to structured youth physical activity opportunities during the COVID-19 pandemic. Key steps in the rapid-cycle research adaptation process included: (Step 1) identifying partner organizations; (Steps 2 and 3) engaging in problem and knowledge exploration to examine the problem from different perspectives; (Steps 4 and 5) initiating solution development and testing by selecting an intervention and adapting the format and content for home delivery. Using Rapid RE-AIM to guide online assessment and refinement of InPACT at Home; and (Step 6) utilizing dissemination strategies to extend the reach of the program. Core elements of the InPACT program that were retained included: the use of exercise videos, maintenance of the intervention dose, and teacher-led physical activities. Key adaptations included: utilization of physical education specialists to develop the exercise videos, incorporation of health messaging in videos, and utilization of dissemination strategies (intervention website) to reach K-12 students across the state. Intervention website reach included all 83 counties in Michigan, but goals were not met for website pageviews (5,147; 85% of goal) and video view duration (7 min 19 sec; 37% of goal). Accordingly, dissemination was expanded to include public television broadcasting (monthly viewers: 500,000) and videos were shortened to 8 minutes. Dissemination and implementation science frameworks guided the rapid adaptation of an existing intervention, InPACT, to equitably increase access to structured youth physical activity opportunities at home during the pandemic.

[Bonding of glass-ionomer cements to tooth hard tissues under various experimental conditions]

In this study the enamel- and dentin-bonding properties of two glass-ionomer cements (ChemFil-II and Ketac-Bond) were evaluated under various test conditions in vitro. The tests showed the following results: 1. ChemFil-II exhibits a significantly stronger bond to the hard tooth substances than Ketac-Bond in the short term test (the samples were stored 2 days in synthetic saliva). The stability of the bond made with ChemFil-II, however, proves in the long term test (the samples were stored 150 days in synthetic saliva) to be less than that made with Ketac-Bond. 2. Acid-conditioning of the enamel does not statistically effect a change in the stability of the bond to any significant degree. Corresponding conditioning of the dentin, on the other hand, causes a definite reduction of the bond to be obtained. 3. Deviations from the powder-liquid mixing ratio recommended by the manufacturer result in a statistically significant reduction in the bond stability, whether these involve an increase in the amount of powder or rather a decrease.
