Attachment Insight

Features
Read full description

Attachment Insight helps you understand how you relate to partners, friends, and the people you care about, using a research-based questionnaire grounded in attachment science, not a gimmicky quiz. Unlike most attachment questionnaires, this app asks about your general patterns across close relationships, not just one romantic partner, giving you a broader and more accurate picture of how you relate to the people you care about. The questionnaire measures two key dimensions of adult attachment: Attachment anxiety: how much you worry about rejection or abandonment Attachment avoidance: how comfortable you feel with closeness and depending on others You'll answer 45 statements about how you typically feel in close relationships. At the end you'll receive a two-dimensional map showing exactly where your scores sit, a label for your attachment pattern (secure, anxious, dismissive avoidant, or fearful avoidant), and concise notes on common thoughts, feelings, and behaviours associated with your pattern. WHY ATTACHMENT INSIGHT? Research-based: Built on established attachment research measuring the two core dimensions used across academic and clinical contexts. No ads, no subscription: One small payment. No intrusive banners, no paywalls. Honest and transparent: We explain what we are measuring and what your scores can and cannot tell you. Attachment patterns are described as changeable tendencies, not fixed diagnoses. Private by design: Attachment Insight does not collect, store, or share any personal data. All responses and scores live only in the app's temporary memory and are gone the moment you close it. Nothing is sent to any server. WHAT'S INCLUDED Full 45-item attachment questionnaire Anxiety and avoidance scores plotted on a visual two-dimensional map Attachment pattern description and reflection notes Retake anytime and compare results manually via the share feature IMPORTANT NOTE Attachment Insight is an educational tool. It does not provide medical, psychological, or therapeutic advice and is not a substitute for professional care. If you are struggling in your relationships or your mental health, please consider speaking with a qualified mental health professional.
