Validity issues, or validiteitskwesties in Dutch, refer to problems or concerns related to the accuracy and trustworthiness of measurement instruments, research findings, or conclusions drawn from data. In essence, they question whether what is being measured or concluded is truly what it purports to be.

There are several types of validity that can be questioned. Construct validity, for example, addresses whether a test or measurement accurately reflects the theoretical concept it aims to measure. Content validity is concerned with whether the content of a measure adequately covers the entire domain of the concept it is intended to assess. Criterion validity examines how well a measure predicts or correlates with an external criterion. Internal validity focuses on the extent to which causal conclusions can be drawn from a study, ensuring that observed effects are due to the manipulated variables and not confounding factors. External validity, on the other hand, deals with the generalizability of research findings to other populations, settings, and times.

Validity issues can arise from various sources, including poorly designed research methods, ambiguous operational definitions, biased sampling, or inappropriate statistical analyses. Addressing these issues is crucial for ensuring the reliability and meaningfulness of research and assessments. Researchers and practitioners must critically evaluate potential validity threats and implement strategies to mitigate them to strengthen the credibility of their work.
