Attachment — AAS-9 two-factor model (anxiety / avoidance)
Two-factor CFA wins for emerging adults (N=307, TLI .985, CFI .993, RMSEA .044). We mirror this structure in our relationship context items.

Educational context only, not a diagnosis or clinical assessment. Product-authored items are labeled where validated instruments do not apply.
§ 01 — Findings
What the study found
- Two factors (anxiety and avoidance) explain attachment in emerging adults better than four-style categorical models.
- Anxiety α=.90, avoidance α=.74 in the AAS-9 validation.
- Four-plus ACEs, depression, and anxiety all predicted higher attachment insecurity.
§ 02 — Encoding
How we encode it
- Why we keep the dimensional anxiety/avoidance signal rather than collapsing to four styles.
- Why we exclude ACEs from the questionnaire (privacy + trauma-informed design) but retain the dimensional signals.
- A future AAS-9-aligned 9-item subscale could ship alongside our product-authored items with explicit provenance labeling.
