Work with IAD Research

The Institute for Adult Development works with postgraduate researchers, supervisors, universities, research groups and organisations investigating adult development, self-awareness, metacognition, cognitive complexity and the construction of human response.

Researchers do not need to begin by agreeing with CDT. Rigorous replication, critique, comparison and investigation of the theory’s limits are welcomed alongside its extension and application.

Postgraduate support Research advisory

Clarify a dissertation or thesis question, identify relevant CDT constructs and understand the theory’s research genealogy.

Universities & research groups Academic collaboration

Develop comparative studies, publications, grant proposals and interdisciplinary research partnerships.

Design & analysis Methods and measurement

Consider study design, construct definition, instruments, coding, mixed methods, replication and responsible interpretation.

Organisations & institutions Commissioned research

Scope rigorous studies into adult development, leadership cognition, education, awareness and developmental practice.

CDT knowledge base Resources and access

Locate primary sources, historical materials and research resources, with data access considered through appropriate governance.

Speaking & review Specialist contribution

Invite a research seminar, critical discussion, subject-matter review or contribution to an academic event.

Bring a question, not a predetermined result. IAD Research supports inquiry capable of strengthening, refining or challenging the theory—not research designed merely to endorse it.
Section 2

Research leadership

Dr Darren Stevens

Founder and Research Director · Originator of Constructed Development Theory

Dr Stevens is available as a research collaborator, subject-matter adviser and independent research consultant. He supports researchers in navigating CDT’s constructs, evidence, unresolved questions and developing research programme.

His contribution can be a single specialist consultation or a longer collaboration shaped around the project, institution, research stage and available funding.

Academic boundary: IAD Research does not replace formal university supervision, institutional ethics approval or academic governance. Formal supervisory, examining or co-investigator roles remain subject to appointment by the relevant institution.
Section 3

Research overview

Constructed Development Theory began as an original programme of doctoral research and has since become a framework used by other researchers to form and investigate their own questions. The IAD’s research role is to document that development accurately, encourage rigorous inquiry and make the available evidence easier to find and assess.

Independent academic use is an important milestone, but it is not presented here as validation by itself. Each study should be evaluated on its research question, method, evidence and conclusions.

Editorial principle: this index will separate completed work, work in progress and proposed research. Details will be added only when they can be published accurately and, where appropriate, with the researcher’s permission.
Section 4

CDT research genealogy

The genealogy records how CDT has moved from the originator’s research into independent academic application. Over time, this section can show not only chronology but also how later studies adapt, question or extend the original constructs.

Foundational research

Doctoral origins of CDT

Dr Darren Stevens’ doctoral research provided the empirical and conceptual foundations from which Constructed Development Theory was developed.

Theory development

Frameworks, constructs and applied methods

CDT developed into an interconnected research programme addressing awareness, the construction of thinking, Cognitive Intentions and Dynamic Intelligence across adult contexts.

Independent uptake

Postgraduate research by other scholars

Two Master’s degrees have now been completed by researchers other than CDT’s originator, with CDT forming a significant part of their academic work.

Emerging programme

New questions, settings and methods

The next phase is to support transparent replication, critique and extension while connecting researchers working across disciplines and regions.

A living genealogy: as the body of work grows, verified studies will be linked to the CDT construct, prior study or applied domain from which they developed. This will make adaptation, critique and extension visible without treating every use of CDT as validation.
Section 5

Completed postgraduate research

This register will provide a stable record of completed dissertations and theses that use, examine or extend CDT. Public entries should include enough information for readers to locate or request the work.

Completed · Master’s research · 2022 Investigation into Procedural & Organisational Justice, Police Legitimacy and Thinking Styles of Lancashire Constabulary Employees

Joseph Spears-Smith’s mixed-methods study examined how Lancashire Constabulary employees understood and enacted procedural and organisational justice, and how awareness and Thinking Styles may influence police legitimacy and “policing by consent”.

Reported findings Procedural and organisational justice were not at the forefront of interviewees’ conscious awareness. The study also found that volunteers could deliver these forms of justice without consciously recognising that they were doing so. The research record identifies further implications where Thinking Styles may constrain delivery or where recruitment and promotion repeatedly select similar styles.

Examiner or supervisor details will appear only when already public or permission has been given.
Section 6

Current research programme

IAD Research is building a programme around questions that can test CDT’s constructs, examine their limits and place them in dialogue with established work across adult development, metacognition, psychology, education and organisational research.

Applied research programme · Team of three IAD Policing & Justice Research Collaborative

Research into police decision-making, investigative thinking, procedural justice, legitimacy, leadership and adult development. Explore the programme →

Proposals invited Independent replication and comparative studies

Re-examine a CDT claim using a new sample, established comparison measure, different cultural setting or independent analytic team.

Partners invited Multi-site and interdisciplinary research

Connect adult development with leadership, education, coaching, cognitive science, organisational life or therapeutic practice.

Project transparency: active studies will be listed only when their scope and public status are confirmed. Each entry will identify whether it is proposed, registered, collecting data, under analysis or being prepared for publication.
Section 7

Core research themes

CDT supports research at the intersection of adult development, cognition, awareness and applied practice. The following themes provide a growing structure for organising studies and identifying gaps.

Awareness and cognitive complexity

How dynamic awareness and the construction of thinking can be conceptualised, observed and measured, including AQ and TQ.

Cognitive Intentions

The underlying heuristics that shape attention, interpretation, choice and response across contexts.

Dynamic Intelligence

The live developmental process connecting Intention, Awareness, Choice and Response, including the IACR process model.

Development in practice

Applications of CDT in coaching, leadership, education, organisational life and other adult-development settings.

Assessment and methodology

Reliability, validity, coding, measurement, mixed methods and the responsible interpretation of developmental data.

Critical and comparative inquiry

Replication, boundary conditions and comparison with related developmental, cognitive and metacognitive theories.

Section 8

Publications & preprints

This catalogue will bring together peer-reviewed articles, books and chapters, conference papers, working papers and preprints. Entries should state their review status and link to the authoritative publisher, repository or persistent identifier.

Publication status matters: peer-reviewed work, postgraduate theses, conference outputs, working papers and preprints will be labelled distinctly. Researchers should cite the specific primary source in which the CDT construct, model or instrument they use is defined, using the bibliographic style required by their institution.
Section 9

Datasets & evidence base

The evidence register will describe the empirical basis available for scrutiny and further inquiry. Its purpose is to clarify what exists, what can be accessed and what restrictions apply—not to imply that all data can or should be openly released.

Foundational research corpus Foundational CDT research corpus

Public descriptions of the doctoral programme report a historical corpus of more than 8,200 Identity Compass self-report profiles, alongside smaller quantitative and qualitative studies. The thesis remains the primary source for assessing the design, analysis, findings and limitations.

Data care: participant confidentiality, informed consent, research ethics and relevant data-protection law take priority over openness. Where raw data cannot be shared, the IAD can still publish useful metadata, methods, codebooks and access procedures.
Section 10

Research standards & governance

IAD Research aims to make collaboration easier without weakening the academic, ethical and legal responsibilities attached to research involving people, developmental assessment or personal data.

Independent scrutiny Critical findings, null results, replication failures and boundary conditions are part of a credible research programme.
Transparent status Proposals, registered studies, preprints and peer-reviewed outputs are identified accurately and not presented as equivalent.
Ethics before access Informed consent, participant confidentiality, safeguarding, institutional approval and data-protection law take priority over openness.
Conflicts made visible The originator’s involvement, IAD support, funding, instrument interests and other relevant relationships should be declared.
Scope of IAD involvement: advice, collaboration or resource access does not constitute ethics approval, institutional sponsorship or formal supervision unless a separate appointment and governance process explicitly establishes that role.
