The relation between childhood and adult attachment is approximately __________.

Question

BlackTom AI · Accepted Answer

Longitudinal research finds a moderate positive correlation (about +.40) between childhood and adult attachment.

1) Relevant knowledge points and concepts
- Attachment theory (Bowlby, Ainsworth) posits early caregiver relationships shape internal working models that influence later relationships.
- Correlation (r) quantifies linear association; r ranges from -1 to +1. r^2 gives proportion of shared variance.
- Measurement: infant attachment typically via Strange Situation; adult attachment via interviews or self-report. Differences in measures and life events reduce perfect stability.

2) Step-by-step reasoning
- Empirical longitudinal studies and meta-analyses (e.g., Fraley and colleagues) report a moderate positive association, not zero or very large. This indicates continuity but also change.
- A value of about r = +.40 is commonly reported as the approximate effect size summarizing these studies.

3) Calculations (intermediate steps)
- If r = +0.40, then shared variance r^2 = 0.40^2 = 0.16.
- Interpretation: 16% of the variance in adult attachment is accounted for by childhood attachment; 84% is due to later experiences, measurement error, or other influences.

4) Why the correct answer is correct
- +.40 reflects moderate stability: early attachment increases the likelihood of similar adult attachment but leaves substantial room for change. This aligns with the literature reporting an average correlation near .3–.4 across studies.

5) Why the other options are incorrect
- 0 would indicate no relation; inconsistent with robust longitudinal findings.
- −.25 implies a modest negative relation, which contradicts the positive continuity observed.
- +.70 implies very high stability (r^2 = 49%), which overstates continuity; empirical data do not support such strong persistence.

6) Conclusion
The best choice, consistent with research evidence and the calculation above, is +.40. This matches the provided correct answer.
