Components of implementation, indicators, data collection and analysis

Component	Indicator	Data collection	Analysis
Preparation phase
Recruitment and evaluation	-Recruitment process -Participant number -Time to recruit -Refusal rates -Feasibility/suitability inclusion criteria -Obstacles recruitment -Relevance of program to population	-Project notes	-Document analysis [32]
Reach	Number of DSPs from team	Project notes during delivery	-Calculation of DSPs from team
Context	-Environment changes (physical, social, political) -Other interventions	-Questionnaire DSPs -Questionnaire managers -Interviews DSPs	-Check on changes in environment beside the program -Check on other interventions (yes/no)
Implementation phase
Dose delivered	Completion program	Project notes during delivery	-Calculation of completion of each part of the program
Dose received	-Execution of assignments -Activity during sessions	-Questionnaire DSPs -Reflection of trainers on sessions -Reflection of researcher (AO) on one session -Quality of assignments	-Descriptive statistics -Quality assignments checked with the following question: ‘Do the assignments show that the DSP understood the assignment?’ [23], and scored according to the following categories: ++ Almost everything on the assignment is correct, + there are more points on the assignment that are correct than points that are not correct, − there are fewer points on the assignment that are correct than points that do not match, -- almost everything on the assignment is not correct.
Fidelity	Execution of sessions by trainers	-Reflection of trainers on sessions -Reflection of researcher (AO) on one session	-Descriptive statistics
Acceptability/suitability program	-Fit of program in daily practice (trainers, DSPs, managers) -Acceptability of program for DSPs and managers -Time/capacity to complete program (DSPs, managers)	-Reflection of trainers on sessions -Questionnaire DSPs -Questionnaire managers -Interviews DSPs	-Document analysis -Descriptive statistics -Conventional content analysis [33]
Factors during implementation	-Facilitators/barriers during implementation (expertise, capacity, budget, equipment available)	-Project notes during implementation	-Document analysis
Evaluation of data collection process	-Feasibility/suitability data collection procedures (missing data, understanding questions, time-consuming) -Sensitivity of outcome measures to changes after the program	-Project notes during data collection -Evaluation of outcomes in relation to methods	-Document analysis
Outcomes
Changes after the program	-Goal achievement after program -Actual application in practice (DSPs, assignments, managers) -Attitude DSPs (T0, T1 and T2) -Food intake people with ID (T0, T2) -Physical activity of people with ID (T0, T2)	-Questionnaire DSPs -Questionnaire managers -Interviews DSPs -Assignments -Food diaries -Actigraph/Actiwatch/ Inventory of daily activity program	-Descriptive statistics -Conventional content analysis [33] -Application check assignments -Attitude changes: linear mixed models [34] in statistical programming language R [35]. -Food diaries: descriptive statistics, Wilcoxon signed Rank test -Actigraph: descriptive statistics, Wilcoxon signed Rank test -Actiwatch: descriptive statistics, calculating %inactive/active time -Inventory of daily activity program: descriptive statistics, Wilcoxon signed Rank test
