How HalfWay Works

A comprehensive guide to our scientifically-backed attachment assessment system: the published 36-item ECR-R (Fraley, Waller, & Brennan, 2000), how responses become anxiety and avoidance scores, and how HalfWay maps those to four attachment styles.

Assessment Process Overview

1. Profile Creation

Partners provide basic demographics and relationship duration to establish context for assessment.

2. ECR-R Assessment

Each partner completes a 36-question scientifically validated attachment assessment independently.

3. Score Calculation

Responses are processed through our algorithm to calculate anxiety and avoidance dimension scores.

4. Insights & Recommendations

Personalized relationship guidance based on your unique attachment style combination.

The ECR-R Framework

Scientific Foundation

HalfWay uses the published 36-item Experiences in Close Relationships—Revised (ECR-R) questionnaire (Fraley, Waller, & Brennan, 2000)—the same stems and reverse-key rules described in standard ECR-R scoring instructions. It remains one of the most widely used self-report measures of adult romantic attachment.

Why this instrument

  • • Two subscales: attachment-related anxiety (18 items) and avoidance (18 items)
  • • Validated extensively in relationship and personality research
  • • 7-point agree–disagree items, with published reverse-keyed items per subscale

ECR-R questionnaire and scoring (PDF) — full item wording and official scoring key (Fetzer Institute handout).

Two-Dimensional Model

ECR-R measures attachment along two independent dimensions:

Attachment-Related Anxiety

Fear of abandonment, need for reassurance, worry about partner's love and availability.

Attachment-Related Avoidance

Discomfort with intimacy, difficulty depending on others, preference for emotional distance.

Assessment Structure

36-Question Framework

Anxiety Dimension (18 questions)

Sample items (anxiety scale):

  • • "I'm afraid that I will lose my partner's love."
  • • "I often worry that my partner doesn't really love me."
  • • "When my partner is out of sight, I worry that he or she might become interested in someone else."
  • • "I rarely worry about my partner leaving me." (reverse-keyed)

Avoidance Dimension (18 questions)

Sample items (avoidance scale):

  • • "I prefer not to show a partner how I feel deep down."
  • • "I feel comfortable sharing my private thoughts and feelings with my partner." (reverse-keyed)
  • • "I don't feel comfortable opening up to romantic partners."
  • • "I get uncomfortable when a romantic partner wants to be very close."

Scoring Scale

Each question is rated on a 7-point Likert scale (1 = Strongly Disagree, 7 = Strongly Agree):

1 - Strongly Disagree
2 - Disagree
3 - Somewhat Disagree
4 - Neither Agree nor Disagree
5 - Somewhat Agree
6 - Agree
7 - Strongly Agree

Note: This 7-point scale matches the published ECR-R. HalfWay shows items 1–36 in order; research studies often randomize item order, which does not change how subscale scores are computed.

Score Calculation Algorithm

Step-by-Step Process

Each raw answer is a number 1–7. For items that are reverse-keyed, the value used in scoring is 8 − raw so that higher always means higher anxiety or higher avoidance on that subscale. Then each dimension score is the mean of those transformed values across that subscale's 18 items (all items are answered in HalfWay).

1

Transform each item

If the item is reverse-keyed: use 8 − response; otherwise use response.

2

Average by dimension

Mean of transformed values for items 1–18 (anxiety) and 19–36 (avoidance).

3

Classify style (midpoint split)

Compare each mean to 4.0 (the midpoint of the 1–7 scale) to assign secure, anxious, avoidant, or fearful-avoidant (see below). This is a fixed cutoff, not a split at your sample's median.

Reverse-keyed item numbers (published ECR-R)

  • Anxiety: items 9, 11
  • Avoidance: items 20, 22, 26, 27, 28, 29, 30, 31, 33, 34, 35, 36

Mathematical Formulas

Per item (before averaging):

x' = 8 − x if item is reverse-keyed, else x' = x

Anxiety score (items 1–18):

anxiety_score = mean(x' for items 1–18)

Avoidance score (items 19–36):

avoidance_score = mean(x' for items 19–36)

Example (illustrative)

Suppose the 18 transformed anxiety values (after reverse-coding items 9 and 11) sum to 95. Then anxiety_score = 95 ÷ 18 ≈ 5.28.

With a 4.0 cutoff, a mean ≥ 4.0 counts as "high" on that dimension for style classification.

Attachment Style Classification

Four-Category Model

Secure

Low Anxiety + Low Avoidance

Anxiety < 4.0 AND Avoidance < 4.0

Anxious (Preoccupied)

High Anxiety + Low Avoidance

Anxiety ≥ 4.0 AND Avoidance < 4.0

Avoidant (Dismissive)

Low Anxiety + High Avoidance

Anxiety < 4.0 AND Avoidance ≥ 4.0

Fearful-Avoidant (Disorganized)

High Anxiety + High Avoidance

Anxiety ≥ 4.0 AND Avoidance ≥ 4.0

Classification Logic (Pseudocode)

if (anxiety < 4.0 && avoidance < 4.0) {
    style = "secure"
} else if (anxiety >= 4.0 && avoidance < 4.0) {
    style = "anxious"
} else if (anxiety < 4.0 && avoidance >= 4.0) {
    style = "avoidant"
} else {
    style = "fearful-avoidant"
}
