VAN IJZENDOORN AND KROONENBERG
- included secure, insecure avoidant and resistant participants across a range of countries
- they looked at the differences within the same countries to get an idea of variations on culture
- 32 studies of attachment where strange situation was used, 8 countries and 15 in the USA
- yield of 1990 children in total
- secure attachment was the most common classification in all countries but ranged from 50% in China, 75% in Britain
- in individualist cultures rates of insecure-resistant attachment was similar to Ainsworth (under 14%), but this wasn't the case with collectivists samples from China, Japan and Israel, where rates were above 25%
- cultural differences in distribution of insecure attachment
- variation of results IN the same country = 150% more than BETWEEN countries
- in USA 46% securely attached, compared to one sample as high as 90%
- assessed 76 12month old babies using the strange situations to see if the proportion of attachment types still matched previous studies
- mums were reasonably varied in terms of education levels, (57% uni degree, 40% high school, 2% didn't finish high school)
Their professions (48% employees, 13% professionals, 39% didn't work/worked part time)
- 50% was secure, 36% avoidant, lower rate of secure attachment than prev
- researchers suggested it was due to incr of mums working and using childcare
- cultural differences make massive differences in patterns of attachment
