VALIDITY

Validity in Psychological Research
Explore the importance of validity in psychological investigations. Validity refers to how accurately a test or study measures what it intends to measure. Internal validity assesses whether results are caused by the independent variable, while external validity considers whether findings can be generalised to real-life and broader populations. Face and concurrent validity assess whether measures are appropriate and match existing, validated tests. Validity is improved through clear operationalisation, controlled procedures, realistic settings, representative samples, and standardised instructions
