Extrinsic factors refer to external influences or conditions that can affect an individual's behavior, attitudes, or characteristics. These factors can include social, cultural, economic, and environmental influences that impact a person's decisions and actions. In research, extrinsic factors are often studied in relation to how they shape individuals' behavior and contribute to outcomes such as academic achievement, job performance, health outcomes, and overall well-being. Understanding and addressing extrinsic factors can help researchers and practitioners develop interventions and strategies to improve individuals' quality of life and success.
