Which of the following is an operational definition of happiness?
An individual’s feeling of joy
An individual’s sense of achievement and spirituality
An individual’s self-rating on a 10-point happiness scale
An individual’s feeling of contentment
The correct answer and explanation is :
The correct answer is:
“An individual’s self-rating on a 10-point happiness scale.”
Explanation:
An operational definition defines a concept in terms of specific, measurable, and observable criteria. It allows researchers to quantify and study abstract concepts like happiness by providing a clear method for measurement.
Among the given options, “An individual’s self-rating on a 10-point happiness scale” is the only choice that meets the criteria of an operational definition. This is because it provides a numerical scale that can be used to collect data, compare results, and analyze trends in a structured manner.
The other options—“An individual’s feeling of joy,” “An individual’s sense of achievement and spirituality,” and “An individual’s feeling of contentment”—are subjective and vague. These descriptions are conceptual definitions rather than operational ones, meaning they describe happiness in a broad way but do not provide a concrete method for measurement.
For example, saying that happiness is a “feeling of joy” does not explain how to measure that joy. Different people may define joy differently, making it difficult for researchers to collect consistent data. However, by asking individuals to rate their happiness on a scale, researchers can quantify happiness, compare responses across groups, and analyze patterns over time.
Operational definitions are crucial in psychology and research because they ensure clarity, reliability, and replicability. Without operational definitions, concepts like happiness would remain too abstract to study scientifically. The use of a 10-point scale, surveys, or physiological indicators (like heart rate or brain activity) are common ways to operationalize emotions and mental states in psychological research.
