Summary
Understanding factors influencing repeated blood donation (RBD) is key for effective interventions. Positive outcome expectations and self-efficacy, alongside mitigating negative experiences, are crucial for promoting RBD behavior.
Area of Science:
- Health Psychology
- Behavioral Science
- Social Cognitive Theory
Background:
- Repeated blood donation (RBD) is vital for blood supply.
- Multidimensional factors influence RBD behavior.
- Effective interventions require understanding these influences.
Purpose of the Study:
- To test a three-stage social-cognitive process model predicting RBD behavior.
- To integrate social-cognitive theory, health action process approach, and theory of planned behavior.
- To identify key mediators and moderators of RBD behavior.
Main Methods:
- 850 blood donors surveyed online in Zhejiang, China.
- Social-cognitive factors measured at baseline.
- RBD behavior tracked via blood donation records for 6 months.
- Structural equation modeling used to test the proposed model.
Main Results:
- Information sources (observational learning, experiences) influenced outcome expectation.
- Outcome expectation and maintenance self-efficacy serially mediated the link between information sources and RBD intention/behavior.
- RBD intention fully mediated the effects of negative experiences, outcome expectation, and self-efficacy on RBD behavior.
Conclusions:
- Findings support a three-stage social-cognitive model for RBD.
- Interventions should focus on enhancing positive outcome expectations and maintenance self-efficacy.
- Mitigating negative donor experiences is essential for promoting sustained blood donation.

01:15Causes of Social Behavior II: Cognitive Processes
205
Cognitive processes affect social behavior by guiding how individuals perceive, interpret, and respond to social stimuli. These mental processes enable individuals to assess others' behaviors, attribute causes to their actions, and form expectations based on past experiences.Causes of Behavior and Social JudgmentsIndividuals determine the causes of others' behaviors by distinguishing between personal traits and external circumstances. For example, if a friend frequently arrives late, an...

01:28Automatic Processing and Automatic Social Behavior
253
Automatic processing refers to the cognitive operations that occur without conscious intent or awareness, playing a fundamental role in shaping social cognition and behavior. These processes enable individuals to navigate complex social environments efficiently by relying on mental shortcuts and pre-existing knowledge structures known as schemas. One of the most influential mechanisms underlying automatic processing is priming, which subtly activates mental representations through exposure to...

Sometimes we want to see how people change over time, as in studies of human development and lifespan. When we test the same group of individuals repeatedly over an extended period of time, we are conducting longitudinal research. Longitudinal research is a research design in which data-gathering is administered repeatedly over an extended period of time. For example, we may survey a group of individuals about their dietary habits at age 20, retest them a decade later at age 30, and then again...

01:23Cognition and Behavior

Social psychology examines the complex interplay between individual mental processes and social interactions. Historically, the field was divided into two domains: social behavior and social cognition. Researchers focusing on social behavior analyzed actions within social contexts, such as conformity, aggression, or cooperation. Meanwhile, social cognition researchers investigated how people perceive, interpret, and mentally represent their social environments. However, modern perspectives no...

Longitudinal studies are also widely used in other medical and social science fields. For instance, in cardiovascular research, they can monitor patients' health over decades to identify risk factors for heart disease, such as high cholesterol or smoking, and evaluate the long-term effectiveness of preventive measures. Similarly, in mental health studies, researchers might follow individuals from adolescence into adulthood to understand the development and progression of conditions like...

01:30Social Cognitive Perspective on Personality
1.0K
Social cognitive perspectives on personality emphasize the importance of conscious awareness, beliefs, expectations, and goals in shaping behavior. These perspectives incorporate behaviorist principles, such as learning through reinforcement and conditioning, but extend beyond them by highlighting human reasoning and planning. Unlike traditional behaviorist views, social cognitive theory focuses on how individuals reflect on their past experiences and plan for future outcomes by considering...
