Table 1

The script choice, purpose, and outcomes.

ScriptPurposeOutcomes

Hopes and fearsTo elicit and to establish group expectations for a GMB sessionList of participants’ hopes and fears with regard to GMB workshop

Graphs over timeTo engage participants at the beginning of GMB session in framing the problem, initiating mapping, eliciting variables, and gathering input in deciding the reference modes for the workshopCandidate variables for the dynamic model or the map

DotsTo vote for what participants considered to be the most important drivers of the modeled problem (i.e., childhood obesity, trends over time identified in the graphs over time exercise)Prioritized choices and the rank of importance of factors contributing to the problem development and persistence over time (i.e., drivers of childhood obesity)

Causal-loop diagram (CLD)To explore the causal factors and the consequences of childhood obesity among Chinese Americans in their community; to pinpoint connections and the nature of the relationship between these factors; and to visualize various interactive causal pathways affecting the weight status of Chinese American childrenA causal loop diagram which may be described either in a report (in the case that only a qualitative model is built), or be used as a dynamic hypothesis on the basis of which formal modeling starts

Model reviewTo present a preliminary synthesis causal loop diagram for review and critique by workshop participantsA revised causal loop diagram and articulation of key feedback loops, narratives, themes, and group understanding of the correspondence between model structure and system behavior

Action ideasTo generate a list of intervention ideas based on the causal structure from the synthesis causal loop diagramA list of intervention ideas including a description of how those intervention ideas may act on the system, including feasibility and barriers and facilitators to impact
