Doctoral foundation

The research from which CDT developed.

Doctoral thesis · 2020

Does Constructed Development Theory Exist as a Conceptual Measure of Self-Awareness in the moment?

Stevens, D. J. (2020). Does Constructed Development Theory Exist as a Conceptual Measure of Self-Awareness in the moment? [Doctoral thesis, Coventry University]. ResearchGate.

The original mixed-methods research programme: its methods, construct definitions, findings and limitations. It provides initial support for parts of CDT while leaving questions for independent validation.

Title follows the ResearchGate record. The later AQ/TQ distinction should not be projected back onto the thesis’s original measures.
