You may find it interesting to read about attachment type correlations with certain countries/ cultures, from a developmental psychology textbook I have: Perhaps surprisingly, the relative incidence of different attachment styles, as measured using Ainsworth’s Strange Situation, varies dramatically across cultures (Thompson, 1998; Van IJzendoorn & Kroonenberg, 1988). Consider, for example, the substantial cultural differences shown in Table 6.2. The majority of German infants studied were measured as insecurely attached (mostly avoidant, or Type A). Japanese infants showed no avoidant attachments whatsoever, and they were almost three times as likely as their American counterparts to show anxious (Type C) attachments. Finally, one group of Israeli children showed almost 10 times as many anxious attachments as Swedish children. Because the procedure used in the Strange Situation is relatively straightforward, it does not seem that these variations can be explained by simple methodological discrepancies in how the assessments were conducted (Harwood et al., 1995; Thompson, 1998; Van IJzendoorn & Kroonenberg, 1988).
