Imago Theory emerged in the early 1980s when psychologists Harville Hendrix and Helen LaKelly Hunt proposed that adult romantic conflict mirrors childhood unmet needs. Their groundbreaking book, *Getting the Love You Want*, introduced the concept of the 'Imago'—the unconscious image of love formed in early years. This framework set the stage for tools that could translate abstract emotional patterns into observable exercises, eventually leading to the trust worksheet’s conception.
The actual worksheet appeared in the mid‑1990s as therapists sought a structured way to assess relational safety. By asking partners to rate trust in specific domains—communication, vulnerability, and reliability—the instrument provided quantifiable data for session planning. Its adoption coincided with a broader move toward evidence‑based practices in psychotherapy, and researchers began publishing early validation studies that linked higher worksheet scores with relationship satisfaction.
