Worldview is the overarching framework through which individuals perceive themselves and their world. It dictates (a) what information individuals seek and (b) how they organize, process, and determine the meaning of information in their social world. Thus, this construct allows for the concurrent examination of both (a) intra-individual-level beliefs and values and (b) external factors that affect behavior. It explores how individuals' unique experience of their world interacts with their self-perceptions to guide the decision-making process. An improved understanding of individuals' worldviews could be used to match interventions to targeted populations at risk to improve health outcomes.
