Scale Validation

Scale validation is the process of ensuring that a measurement tool or questionnaire accurately and consistently assesses what it’s intended to measure. It involves testing the scale's reliability (producing stable and repeatable results) and validity (actually measuring the desired concept). This process confirms that the scale provides meaningful, trustworthy data, allowing researchers or practitioners to interpret the results confidently. In essence, scale validation ensures that the tool is both accurate and dependable for its specific purpose.
