Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Households enrolled into the control and the BioLite arms of GRAPHS (the parent study) will receive clean LPG cookstoves for their participation in the study (clinicaltrials.gov registration: NCT01335490). The objective of this study is to test the relative impact of two approaches to encourage stove use: providing a behavior change intervention and offering convenient access to LPG refueling. The investigators hypothesize that these interventions will increase overall use of LPG cook stoves.
Prior evidence on the role of health information in promoting the adoption of health-promoting technology is limited, and the results are mixed. Although little work has been done to investigate the importance of accessibility to sustained use of cookstoves, accessibility remains one of the basic market drivers of product demand.
A total of 27 communities will be cluster randomized, with 979 study households nested throughout the sites. The study arms will be arranged as a 2x2 factorial design, with approximately equal numbers of households in each arm.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Control
All individuals in each arm will receive a new LPG cookstove. The control arm will receive an orientation for safe operation of the new LPG stove. Participants in the control arm will, however, receive no other intervention.
No interventions assigned to this group
No Delivery, Educational Intervention
All individuals in each arm will receive a new LPG cookstove. This intervention arm receives a health promotion intervention based on the Risks, Attitudes, Norms, Ability, and Self-Regulation (RANAS) model.
RANAS Behavior Change Intervention
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.
Delivery, No Educational Intervention
All individuals in each arm will receive a new LPG cookstove. This intervention arm receives free direct delivery of their LPG cylinder refills upon demand.
Infrastructural Intervention - Direct Delivery
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.
Agent Delivery, Educational Intervention
All individuals in each arm will receive a new LPG cookstove. This intervention arm receives free direct delivery of their LPG cylinder refills upon demand. Participants in this arm also receive a health promotion intervention based on the Risks, Attitudes, Norms, Ability, and Self-Regulation (RANAS) model.
