Egoism and Altruism

Egoism and Altruism

Voluntary behavior with the intent to help other people is called prosocial behavior. Why do people help other people? Is personal benefit such as feeling good about oneself the only reason people help one another?

Social Exchange Theory

Social Exchange Theory

As formulated by John Thibaut and Harold Kelley, Social Exchange Theory explains human relationships as economic-like exchanges that maximize rewards and minimize costs. This theory suggests that individuals engage in relationships to gain benefits and reduce burdens, similar to economic transactions. It has been widely applied to various types of relationships, including romantic, professional, and social interactions.Rewards and Costs in RelationshipsRelationship rewards include emotional...

Social Exchange Theory

Social Exchange Theory

We have discussed why we form relationships, what attracts us to others, and different types of love. But what determines whether we are satisfied with and stay in a relationship? One theory that provides an explanation is social exchange theory. According to social exchange theory, we act as naïve economists in keeping a tally of the ratio of costs and benefits of forming and maintaining a relationship with others (Rusbult & Van Lange, 2003).

Longitudinal Research

Longitudinal Research

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...

Surveys

Surveys

Often, psychologists develop surveys as a means of gathering data. Surveys are lists of questions to be answered by research participants, and can be delivered as paper-and-pencil questionnaires, administered electronically, or conducted verbally. Generally, the survey itself can be completed in a short time, and the ease of administering a survey makes it easy to collect data from a large number of people.

Self-Serving Bias

Self-Serving Bias

Self-serving bias is a cognitive phenomenon in which individuals attribute positive outcomes to internal factors such as their abilities, intelligence, or effort while attributing negative outcomes to external circumstances. This cognitive distortion helps maintain self-esteem but can also impede objective self-assessment.Theoretical Explanations of Self-Serving BiasTwo primary theories explain the self-serving bias: the cognitive explanation and the motivational explanation.The cognitive...

Summary

Understanding donor return behavior is crucial for blood supply. Repeat donors are more likely to be male, older, and married, with previous donation history significantly predicting return.

Area of Science:

Blood Transfusion Medicine
Public Health
Donor Behavior Studies

Background:

Maintaining an adequate blood supply necessitates understanding and improving donor return behavior.
Converting first-time blood donors into repeat donors is a key strategy for blood centers.

Purpose of the Study:

To analyze the characteristics of first-time versus repeat whole blood donors in China.
To identify predictors of donor return behavior for subsequent whole blood donations.

Main Methods:

Compared characteristics of 241,552 whole blood (WB) donations from first-time and repeat donors in China (2008).
Analyzed return behavior of 54,394 WB donors from Jan-Mar 2008 for subsequent donations within 2008 using logistic regression.

Main Results:

First-time donors constituted 64% of all donations; repeat donors were typically male, older, and married.
14% of donors who donated between Jan-Mar 2008 returned for subsequent donations by year-end.
Previous donation count and collection location (vehicle vs. center) were strongest predictors; prior donations increased return likelihood significantly (3.7-11.0x).

Conclusions:

The majority of China's blood supply originates from first-time donors.
Targeted strategies are essential to encourage first-time donors to become repeat donors.
