Table 5 Examples of Intervention Functions implemented by fieldworkers to promote LPG gas use behaviors among women who are the household cooks

From: Designing a behavioral intervention using the COM-B model and the theoretical domains framework to promote gas stove use in rural Guatemala: a formative research study

Behavior Targeted Intervention function Example Method for assessing whether intervention function was achieved
Initiation of stove use and safety checking Training With another cook in home (preferably mother-in-law), demonstrate sequence of lighting stove, changing fuel tank and checking for leaks At next visit, other cook return-demonstrates steps for one of these sequences.
Recognize and avoid smoke exposures in family members, including children Education With other adult family members in home, discuss signs and symptoms of low birth weight, pneumonia and chronic obstructive pulmonary disease. Explain why smoke from cooking fires exacerbates conditions. Ask if they have seen conditions and what they can do to avoid smoke. At next visit, household member states two health conditions or diseases caused or exacerbated by HAP and names one action they have done to avoid smoke exposure.
Cooking with gas stove instead of woodstove Persuasion Show video of several women cooking together in smoke-free clean kitchen, with testimony from mother-in-law about how she likes her kitchen clean and free of smoke. Ask if this reflects the reality in their home. At next visit, praise them if they have used their gas stove more frequently (measured by days from last tank refill). If they have not, ask them what they remembered about video they saw last time.
Cooking with gas stove instead of woodstove Incentivization Tell family that they will receive a prize if they use their stove two times a day for one week. At next visit, reward the family with small bag of beans and rice if they adhered to stove use for 1 week
Cooking with gas stove instead of woodstove saves time Modelling Fieldworker discusses her use of gas stove and how this has benefitted her daughters-in-law who live with her, including their ability to earn more income performing other tasks, like raising animals to sell. Ask woman if she remembers the conversation with the fieldworker from the previous visit. Ask her what things she could do with more time freed up from cooking.
Initiate tank refill before field team’s next visit
(family level)
Enablement Ask tank delivery service to visit home with fieldworker to provide contact information and discuss future deliveries. Within one month after end of study, family has elicited LPG tank refill and the tank was delivered to the home.
Attempted/successful trouble shooting discussion with others in home of kitchen smoke risks (family level) Environmental Restructuring Discuss material costs for modifying kitchen to include an extra window with husband. Show a video of a man discussing the benefits to his family after he made this change. Trouble-shoot barriers and enablers to making structural changes in the home. At the end of the study, reassess if any household modifications have been done that improves ventilation in the kitchen, such as new window or added door, or new kitchen where gas stove is located.
