The Strange Situation procedure is used to assess individual differences in attachment types and can be used to investigate cultural variations.
Van Ijzendoorn & Kroonenberg's (1988) meta-analysis examined 32 studies from 8 countries and found that intra-cultural variation in attachment was greater than cross-cultural variation.
The study found that secure attachment was the most common (65%), followed by avoidant (21%) and resistant (14%).
Differences in socio-economic factors and levels of stress were speculated to contribute to the variations in attachment patterns.
Takahashi (1990) replicated the Strange Situation with Japanese infants and found distinct cultural differences in their responses. He found that 0% of infants were insecure-avoidant, 32% were insecure-resistant, and 68% were secure.
The strange situation has been used in a variety of cultural settings to identify whether patterns of attachments are universal or are subject to cultural influences.
Van Ijzendoorn studied cultural variations in the UK, USA, Sweden, Japan, China, Holland, Germany & Israel.
In the 32 studies nearly 2000 Strange Situation classifications were documented in total.
In Van Ijzendoorn's study average findings were consistent with Ainsworth’s original research.
Japan & Israel revealed a higher incidence of insecure resistant rather than insecure avoidant children.
Chinese findings revealed the lowest rate of secure attachments (50%) with the remaining children falling into the other categories equally.
It was concluded that there are cross-cultural differences in attachment.
Germany had a higher incidence of insecure avoidant (35%) than insecure resistant types.
Inter-cultural difference are between countries where as intra-cultural are differences within the same country.
The UK and Sweden had the highest rates of secure attachment types.
The UK had 75% of secure attachments.
Sweden had 74% of secure attachment types.
Germany had 35% of insecure avoidant attachment types.
Israel had the highest % of insecure resistant attachment types (29%).
In Van Ijzendoorn overall most children are securely attached.
In individualistic cultures secure attachment was greater.
In collectivist cultures the rates were greater for insecure attachment types when comparing individualistic cultures.
There was more variation from within the cultures (intra-cultural) especially in Israel.
