What term refers to the extent to which a theory is internally consistent?

The term that refers to the extent to which a theory is internally consistent is logical soundness. Logical soundness signifies that the premises of a theory lead to conclusions that are coherent and do not contradict each other. This coherence ensures that the theory can adequately explain the phenomena it intends to address and provides a stable framework within which the concepts and propositions of the theory operate.

A theory that exhibits logical soundness demonstrates that its assertions can be logically derived from its foundational premises, making it a reliable guide for understanding and analyzing crime-related behaviors or patterns. This quality is crucial for any theoretical framework, as it establishes the credibility and trustworthiness of the theory in the field of criminology.

In contrast, experimental validation concerns the ability of a theory to be tested and confirmed through empirical research, while statistical significance relates to the likelihood that observed results are not due to chance. Theoretical robustness is about the theory's ability to withstand scrutiny and remain applicable across various contexts, but it does not specifically address internal consistency. Therefore, logical soundness precisely captures the internal coherence that is essential for a credible theoretical foundation.
