Encouraging LPG Adoption in Ghana: A Factorial Randomized Clinical Trial to Enhance LPG Adoption & Sustained Use

The Risks, Attitudes, Norms, Abilities, and Self-Regulation (RANAS) Model is a health behavior change intervention, which has been successfully used in the area of water, sanitation, and hygiene. It draws from numerous health behavior theories, including the Theory of Planned Behavior, the Health Action Process, and the Health Belief Model. The model posits that the five factor blocks (risks, attitudes, norms, abilities, and self-regulation) that must be aligned toward the new behavior in order to influence change. A series of activities target each block accordingly.

Product demand is influenced, in part, by accessibility. Investigators are testing the degree to which this is true for liquefied petroleum gas (LPG) by establishing a direct delivery system for communities randomized to this treatment arm. Individuals in these communities are able to contact a 'delivery agent', contracted by the Kintampo Health Research Centre, who will: 1) retrieve their cylinder, 2) refill with LPG, and 3) return to the participant. The cost of delivery is free to the participant (paid by the study), but the participant is expected to fully pay for their own LPG.
