## Precise definition
The Closeness Inventory is a practical educational guide that helps two people in a relationship improve closeness by deliberately building shared life. It defines closeness primarily as behavioral interdependence across ordinary weeks, not only as intensity of romantic feeling.

## Core model (F / D / S)
1. Frequency
   Meaning: How much real time partners spend together without constant distraction.
   Practice examples: protected phone-down blocks; shared meals; walks; weekly anchor time.

2. Diversity
   Meaning: How many different life domains are shared, not only one routine lane.
   Practice examples: errands together; planning; play; hard conversations; future logistics; learning something jointly.

3. Strength
   Meaning: How much partners kindly and mutually influence each other's decisions, priorities, and days.
   Practice examples: invited input; collaborative planning; support requests; mutual adjustment without coercion.

## Research lineage (accurate framing)
The product is inspired by the Relationship Closeness Inventory (RCI) scientific tradition associated with:
- Ellen Berscheid
- Mark Snyder
- Allen M. Omoto
- 1989 Journal of Personality and Social Psychology article on assessing closeness of interpersonal relationships

Important boundaries:
- This product is a practical translation for ordinary couples.
- It is not a republished proprietary questionnaire item set.
- It is not a clinical diagnostic instrument.
- It is not psychotherapy or medical treatment.

## Problem it addresses
Modern dating and relationship culture often trains people to rank partners like inventory (status, optics, checklists). Couples can still care deeply while ordinary shared life becomes thin. The guide provides language and weekly practices to rebuild interconnection without turning partners into scores.
