Comparative analysis: MindNavigator vs. psychodiagnostic assessment
A case comparison (December 2025) contrasting a MindNavigator Free report with a traditional psychodiagnostic report—and highlighting why ecological validity and context (e.g., school trajectory) are critical in interpretation.

Executive summary
We compare a traditional psychodiagnostic report (PO) with a MindNavigator Free report for the same adolescent. Both identify similar executive-function themes. The key difference lies in interpretation and ecological validity: how test outcomes are weighed against proven real-world functioning.
Key finding: interpretation vs. real-world functioning
In the PO, an education-level conclusion was drawn from test scores that did not match years of proven school functioning. The MindNavigator Free report doesn’t “solve” this by itself, but it does help frame the core issues as executive execution (how) rather than capacity (whether).
Why this matters clinically
Ecological validity (track record) is often a stronger indicator than a single test session—especially with ADHD, overload, or low test motivation. This case shows how quickly interpretation can derail when school trajectory and context factors are not explicitly incorporated.
1. Methodological comparison
Three approaches, each with their own strengths: from quick screening to comprehensive diagnostics.
2. Multi-informant approach
Multi-informant data is a strength of traditional diagnostics (youth, parents, school). MindNavigator Free is primarily single-informant (self-report), and is therefore best positioned as a preparatory layer: fast, accessible, and useful for clarifying the clinical question.
Current (Free): single-informant
The Free report captures the youth’s self-view of executive functioning. Clinically relevant (insight, subjective burden), but it benefits from triangulation: parent/school observations and context factors often determine “where” and “when” problems emerge.
What Premium can add
Premium can add parent perspective and additional context questions (including school history). This makes discrepancies visible and strengthens interpretation against “test-day effects” and context-blind conclusions.
3. Convergent findings
Despite different methodologies, both reports identify largely the same core patterns—supporting validity as a preparatory intake layer.
- Inhibition/impulse control: clearly flagged in both reports.
- Planning & organization: consistently identified as challenging.
- Flexibility as a strength: a notable alignment (normal/strong range).
- Working memory: both indicate vulnerability, with PO measuring it more explicitly via standardized testing.
4. The validity issue: where interpretation can derail
In this case, tension emerged between test outcomes and proven real-world functioning. This is not "tests are bad", but an interpretive risk when ecological validity, existing diagnoses, and context factors are not sufficiently weighted.
The core errors (in brief)
Test scores were interpreted as a hard ceiling for educational level, while the adolescent had been at pre-university level for 5 years without repeating a grade (started at gymnasium). With ADHD and variable test engagement, performance under artificial conditions is especially vulnerable to underestimation.
Existing diagnosis insufficiently incorporated
The adolescent had an official dyslexia diagnosis (dysorthographia, DSM-5 F81.1), registered with the national quality institute, with structural school accommodations (extra time, laptop, audiobooks). This diagnosis was explicitly mentioned by parents during intake AND known to the school informant. Yet dyslexia was only mentioned in passing in the conclusion, without systematic integration in: the developmental history, WISC-V score interpretation (especially processing speed and working memory), or treatment recommendations.
The pattern where Picture Concepts scores higher than Digit Span is often seen in dyslexia (phonological vs. visual-spatial working memory). This was not considered in the interpretation.
Disproportionate school advice
The report recommended adjusting to a lower educational track, while: the adolescent had been at pre-university level for 5 years without grade repetition, started at gymnasium, scored above average on verbal comprehension (a core skill for pre-university), and the failing grades in year 4 were a dip, not representative of the entire school career. No consideration was given to first implementing interventions (ADHD treatment, optimizing dyslexia support) before adjusting school level.
💡 Professionele takeaways: (1) Actively ask about existing diagnoses and process them systematically. (2) Explicitly weigh track record (school trajectory). (3) Phrase conclusions in terms of execution/conditions ("how") rather than capacity ("whether"). (4) Consider interventions before recommending structural changes.
5. How MindNavigator helps prevent this
MindNavigator systematically asks for the context that was missing in this case: existing diagnoses, school history, and prior support. This information is structurally integrated into the report.
Standard intake questions (Premium)
- •Are there existing diagnoses? (dyslexia, ADHD, ASD, etc.) — with space for details and registration numbers
- •What accommodations/support does the adolescent already receive? (extra time, tools, guidance)
- •School trajectory: current level, starting point, grade repetitions, track changes
- •What are the strong subjects and where are the challenges?
- •Are there life events or changes that may be relevant?
Why this makes a difference
In the case study, dyslexia was mentioned in passing despite explicit reporting by parents AND awareness by the school informant. MindNavigator enforces this information through structured questions and automatically integrates existing diagnoses into interpretation. Discrepancies between informants (youth vs parent/school) are explicitly shown.
“Example report phrasing: "There is an existing dyslexia diagnosis (nationally registered) with school accommodations. The executive profile shows challenges in working memory and processing speed — patterns often associated with dyslexia. The 5-year pre-university track without grade repetition suggests capacity is not the core issue; challenges appear primarily executive in nature."”
Practical use in your workflow
Use this output as a preparatory layer: faster triage, better question formulation, and a richer starting point for clinical observation.
- Pre-intake triage: who needs specialist diagnostics, and who mainly benefits from psychoeducation/strategies?
- Hypothesis building: where do you expect context discrepancies (school vs home) and why?
- Psychoeducation: language and strategies that adolescents actually want to use (empowering, concrete).
- Shared decision making: explicitly separate “known” vs “to be assessed”.
8. Positioning implications
This case supports a complementary positioning: MindNavigator as preparation for or an adjunct to professional trajectories—not a replacement.
- "Multi-informant without waiting": youth + parent in one accessible format.
- "Context professionals miss": school history is captured systematically.
- More robust than test-day dependent measurements: multiple perspectives + objective school-trajectory context.
- Scalable to school context: prepared for mentor/teacher perspective.
- Complementary to diagnostics: ideal as preparation/adjunct, not a replacement.
