Which of the following is an operational definition of “happiness”?
a. It is a feeling of joy or contentment.
b. It is the number of times an individual smiles in an hour.
c. It is an individual’s self-rating on a 10-point happiness scale.
d. Both B and C are operational definitions of happiness.
The correct answer and explanation is :
Correct Answer:
d. Both B and C are operational definitions of happiness.
Explanation:
An operational definition defines a concept in measurable, observable terms, making it possible to study it scientifically. In psychology, concepts like “happiness” are abstract and subjective, so researchers must create operational definitions to measure them in a standardized way.
Why B and C Are Operational Definitions:
- Option B (the number of times an individual smiles in an hour) is an operational definition because it provides a quantifiable, observable way to measure happiness. Smiling is often linked to positive emotions, and counting smiles allows researchers to objectively assess happiness.
- Option C (an individual’s self-rating on a 10-point happiness scale) is also an operational definition because it translates happiness into a numerical value based on self-reported feelings. While subjective, self-reported scales are widely used in psychological research to measure emotions.
Why Option A Is Not an Operational Definition:
- Option A (a feeling of joy or contentment) is a conceptual definition rather than an operational one. It describes what happiness is but does not specify how to measure it in a research setting. While this definition helps in understanding the concept, it is too vague for scientific study.
In research, operational definitions are crucial because they allow for replication, comparison, and statistical analysis. Without them, studying abstract concepts like happiness would be impossible. By using measures like smile frequency and self-reported ratings, researchers can systematically investigate happiness and its influencing factors.
