The Unified Intimacy Intelligence Assessment synthesizes validated instruments from attachment science, the Gottman Institute, sexual response research, values psychology, and emotional intelligence into a single integrated framework. Every question maps to published research. Every score has a citation.
Every question maps to validated instruments with published Cronbach's alpha, test-retest reliability, and cross-cultural validation data.
Domain weights reflect clinical importance: Attachment (30%), Communication (25%), Sexual (20%), Values (15%), EI (10%) — based on meta-analytic effect sizes.
Unlike siloed assessments, we model cross-domain interactions. Your attachment affects your sexuality, which affects your communication, which affects your values.
Click each domain to see the specific instruments, reliability coefficients, validation data, and seminal papers that inform your scores.

Good science requires honesty about limitations. Here's exactly where the UIIA stands and what we're doing to improve.
The UIIA is a living instrument. Like the research it's built on, it evolves with new data, new participants, and new scientific findings.
Norming study with 1,000+ respondents to establish population benchmarks
Item Response Theory (IRT) analysis to optimize question discrimination and difficulty
Adaptive testing — questions adjust based on prior answers for higher precision in fewer items
Couples comparison module with dyadic scoring and interaction pattern analysis
Longitudinal tracking — retake every 90 days to measure growth and pattern shifts
AI-enhanced interpretation with natural language processing for open-ended responses
