Dimensions are different parts of a construct that are coherently linked to make it up as a whole. Simple constructs tend to be narrowly defined, while complex constructs are broader and made up of dimensions. Observations: Ask participants to perform simple tasks, such as picking up an object or drawing a cat, and observe which hand they use to execute the tasks.Ī more complex concept, like social anxiety, requires more nuanced measurements, such as psychometric questionnaires and clinical interviews.A simple survey question: Ask participants which hand is their dominant hand.

For example, a concept like hand preference is easily assessed: You need to investigate a collection of indicators to test hypotheses about the constructs.Ĭonstructs can range from simple to complex. You can’t directly observe or measure these constructs. Example: ConstructsPsychologists develop and research constructs to understand individual and group differences. It’s a variable that’s usually not directly measurable. Frequently asked questions about construct validityĪ construct is a theoretical concept, theme, or idea based on empirical observations.Criterion validity: Do the results accurately measure the concrete outcome they are designed to measure?.Face validity: Does the content of the test appear to be suitable to its aims?.Content validity: Is the test fully representative of what it aims to measure?.Types of measurement validit圜onstruct validity is one of four types of measurement validity. You need multiple observable or measurable indicators to measure those constructs or run the risk of introducing research bias into your work. It’s crucial to establishing the overall validity of a method.Īssessing construct validity is especially important when you’re researching something that can’t be measured or observed directly, such as intelligence, self-confidence, or happiness. Start citing Construct Validity | Definition, Types, & ExamplesĬonstruct validity is about how well a test measures the concept it was designed to evaluate.
