/**
 * ECR-R — Experiences in Close Relationships-Revised (adult attachment).
 *
 * 36 items on a 1–7 agreement scale: items 1–18 form the attachment
 * anxiety subscale, items 19–36 attachment avoidance (Fraley, Waller &
 * Brennan, 2000). Subscale results are reported as sums (18–126); the
 * published convention is the item mean — divide by 18. The dimensions
 * are continuous; no clinical cutoffs exist, so no bands are defined.
 *
 * Research use only: the items are published for use in the public
 * domain for non-commercial research; commercial use requires the
 * authors' permission. The Turkish locale pack reproduces the validated
 * YİYE-II adaptation (Selçuk, Günaydın, Sümer & Uysal, 2005).
