In case there are some missing aspects from the measurement or you included irrelevant aspects, the validity is at stake. In order to generate valid results, it’s essential that the content of the survey, test or any measurement method you use must cover the relevant & necessary areas of the subject it intends to measure. Anxiety can be measured by symptoms such as restlessness, edginess, difficulty concentrating, and others.Ĭontent validity is used for evaluating if a test can represent the different aspects of a specific construct. Happiness can be measured by the indicators such as high energy, positivity, frequency of laughing, and smiling. We can only measure emotions based on a collection of indicators. Construct validity examples:Įmotions don’t have any unit that can help us measure them directly. So, the questionnaire should include only the relevant questions that can effectively gauge the popular indicators of depression. Suppose you plan to build a questionnaire for the diagnosis of depression, it’s essential for you to know: is your questionnaire really able to measure the construct for depression? Or does it measure the respondent’s behavior, level of happiness, or some different construct?įor attaining construct validity, it’s imperative to make sure that the indicators you use are cautiously developed on the relevant existing knowledge. What does construct validity mean?Ĭonstruct validity is a great way of ensuring that the measurement method aligns well with the construct that you aim to measure. Although, these may comprise wider concepts too that are applied to social groups or bigger organizations, such as social responsibilities, freedom of choice, gender equality, freedom of speech, etc. The constructs may constitute characteristics seen in individuals like happiness, intelligence, satisfaction, fitness, depression, etc.
However, you can measure it by observing the indicators that are related to it. What is a construct?Ī construct can be defined as a characteristic or concept that you cannot observe directly. It plays a key role in signifying the overall validity of a specific method.
With the help of construct validity, it becomes easy to evaluate if a particular measurement tool actually represents the thing that we want to measure.
