Final answer:
Job satisfaction is the term used to describe the pleasant feeling when one's job aligns with their important values, and it's most strongly affected by the work content itself. Job satisfaction is measured using questionnaires and is a key area of focus within organizational psychology, a subfield of I-O psychology.
Step-by-step explanation:
The term for the pleasant feeling resulting from the perception that one's job fulfills important job values is job satisfaction. Job satisfaction is impacted by various factors such as the work itself, the individual's personality, and the cultural context. Edwin Locke defined job satisfaction as the state of feeling resulting from appraising one's job experiences, where it encompasses both cognitive and affective aspects.
Research has indicated that work content, which involves factors like variety, difficulty level, and role clarity, is the most strongly predictive factor of overall job satisfaction. This prevailed over other factors such as financial rewards, suggesting the importance of the work's intrinsic characteristics over extrinsic rewards. Moreover, job satisfaction can be measured through different methods, such as questionnaires with Likert scales.
Additionally, within the field of I-O psychology, job satisfaction is primarily studied under the branch of organizational psychology. This field examines various aspects of the workplace and how they influence employees' attitudes and behaviors, including their levels of job satisfaction.
