Lonely Index Methodology

Dimensions and weights

We score loneliness across five drivers. Each dimension is normalized to 0-100 percent (higher means more risk):

• Subjective Loneliness: felt connection and belonging.
• Expectation-Reality Gap: when hopes and outcomes diverge.
• Digital Dependence: the balance of online and in-person signals.
• Social Frequency: weekly opportunities to connect.
• Relationship Quality: depth, safety, reciprocity.

Total score S is a weighted blend (0 is best, 100 is worst):

S = 0.35 L + 0.25 G + 0.15 D + 0.125 (100 - F) + 0.125 * (100 - Q)

Reverse scored items are handled before aggregation; all subscales use the same 1-5 Likert base.

Reliability and confidence

• Short term noise: mood and context can sway answers; compare results across two to four weeks.
• Consistency: focus on direction and repeated confirmation (for example, total -6 with Gap -8).
• Actionability: small, repeated micro tasks create signal faster than a single burst of effort.

Ethics

• Minimization: we collect only what is needed to show progress and run your account.
• Anonymization: star map shares are opt in and can be public, anonymous, or private.
• Control: export or delete on request; the tool is educational, not medical advice.
