Question 1

What is a psychological fitness tracker?

Accepted Answer

A psychological fitness tracker is a platform that enables you to measure and monitor your psychological development over time — in the same way a fitness tracker monitors physical health metrics. The Self Index is the world's leading psychological fitness tracker, providing 13 validated psychometric assessments that build a longitudinal profile of your emotional intelligence, resilience, personality, and behavioural patterns. Unlike traditional personality tests that deliver a single static snapshot, theSelfIndex tracks how these dimensions change as you grow.

Question 2

How is theSelfIndex different from a personality test?

Accepted Answer

Traditional personality tests — including MBTI, Big Five, and similar instruments — provide a static snapshot of who you are at a single point in time. theSelfIndex is a longitudinal psychological tracking platform: it establishes your psychological baseline across multiple validated instruments and measures how your emotional intelligence, resilience, values, and behavioural patterns develop over time. The distinction is the difference between a photograph and a time-lapse — one captures a moment, the other reveals a trajectory.

Question 3

What is a psychological baseline?

Accepted Answer

A psychological baseline is your initial calibrated measurement across key psychological dimensions — emotional intelligence, resilience, character strengths, cognitive style, attachment patterns, and values. Establishing a baseline is the first step in longitudinal psychological tracking. theSelfIndex builds your baseline through its Emotional Intelligence assessment and expands it across all 13 instruments, enabling you to measure meaningful change over time.

Question 4

What is The Self Index?

Accepted Answer

The Self Index is a science-based psychological fitness tracker offering 13 validated psychometric instruments across five domains: Identity, Relationships, Cognition, Wellbeing, and Purpose. It is designed for adults seeking to establish a psychological baseline and track meaningful personal development over time — the psychological equivalent of a fitness tracker.

Question 5

Are the assessments scientifically validated?

Accepted Answer

Yes. Every assessment on The Self Index is based on peer-reviewed psychometric instruments used in academic research and clinical practice. These include the Big Five (OCEAN), the Schutte EI Scale, the Connor-Davidson Resilience Scale, the VIA Character Strengths inventory, and others. See our Methodology page for full references.

Question 6

Can I try the assessments for free?

Accepted Answer

Yes. Four free taster assessments are available with no account required: Attachment Style, Emotional Intelligence, Character Strengths, and Dark Triad. Each taster gives you a partial result and a prompt to unlock the full report and begin building your longitudinal psychological profile.

Question 7

How long does each assessment take?

Accepted Answer

Most assessments take between 5 and 12 minutes. The IQ assessment takes approximately 20 minutes. The full psychological profile (all 13 assessments) takes around 2 hours in total and can be completed across multiple sessions.

Question 8

Is my data private?

Accepted Answer

Yes. Your individual assessment results are never shared with third parties. In the school version, student results are kept strictly private and are never visible to teachers or school administrators — only anonymised aggregate data is available to schools.
