They conducted a meta-analysis of data from various studies that used the Strange Situation procedure to assess attachment patterns in infants
The studies included samples from different cultures and countriesworldwide
Findings: Van Ijzendoorn & Kroonenberg
They found that variation within cultures was 1.5x greater than variation between cultures.
These results led them to conclude that secure attachment is the norm and that this type of attachment is the best for healthydevelopment
How much data did Van Ijzendoorn & Kroonenberg analyse?
32 studies
8 different countries
2000 infant participants
Aim: Van Ijzendoorn and Kroonenberg (1988)
aimed to investigate if attachmentstyles (secure and insecure) are universal across cultures, or culturallyspecific (vary considerably from place to place, due to traditions, the social environment, or beliefs about children)
Findings: Van Ijzendoorn and Kroonenberg (1988)
Non-westerncollectivistcountries like Japan (27%) & Israel (29%) revealed a higher incidence of resistant than avoidant children
whereas individualisticwesterncountries like Germany (35%) had a higher incidence of avoidant than resistant
Chinese findings revealed the lowest rate of secure attachments (50%) with the remaining children falling into the other categories equally
Britain had the highest rate of secure attachments (75%).
