van IJzendoorn & Kroonenberg
Evaluation
Procedure:
- Conducted a meta-analysis of 32 studies across 8 countries.
- The studies selected used the Strange Situation to assess attachment type between infant and mother.
- 15 studies had been conducted in the US.
- Overall results from 1,990 children were analysed.
Findings:
- Secure attachment was the most common attachment type in every country.
- Insecure-avoidant was the next most common except in Israel and Japan.
- The variation within countries was 150% greater than variation across countries. E.g. one study in the US found only 46% securely attached compared to another sample as high as 90%
Unrepresentative of Culture
Imposed Etic
Large Samples
- By combining results of attachment studies carried out in different countries, you end up with a very large sample.
- This increasing internal validity by reducing the impact of anomalous results caused by bad methodology or very unusual participants.
- SS was designed by an American researcher based on a British theory.
- Trying to apply this to another culture is known as imposed etic.
- For example, in SS a lack of separation anxiety and pleasure on reunion may indicate an insecure attachment.
- But in Germany this is seen as independence.
- Meta-analysis by van IJzendoorn and Kroonenberg claimed to study cultural variation, whereas the comparisons were really between countries.
- Within any country, there are many different cultures with different child-rearing practices.
- Sagi found distributions of attachment type in an urban setting were similar to Western studies, but a rural sample had more IR individuals.
- Means that comparisons between countries may have little meaning and the particular cultural characteristics of the sample need to be specified.
Alternative Explanation for Cultural Similarity
Lacks Validity
- The SS lacks validity.
- Kagan suggested attachment type is more related to temperament than the relationship with the PAF.
- The SS is not measuring attachment, just anxiety.
- Bowlby's explanation for cultural similarities is that they are due to attachment being innate and universal.
- V & K proposed an alternative explanation, suggesting that small cross-cultural differences reflect the effects of the mass media which advocate similar notions of parenting.
Italian Study
Simonella et al. (2014):
- Investigated if the proportion of current attachment types match findings of previous research.
- Assessed 76 one year olds using the SS.
- 50% - secure and 36% - IA.
- Lower rate of secure type compared to previous findings. This could be due to mothers of young children having to work increasingly long hours and use childcare.
- This suggests cultural changes can have a dramatic impact on patterns of secure and insecure attachment.
Korean Study
Jin et al. (2012):
- Compared proportions of attachment types in Korea to other studies.
- Assessed 87 children using the SS.
- Overall proportions of secure and insecure babies were similar to most countries.
- Those classed as insecurely attached were all resistant except for one avoidant child.
- This is similar to the attachment type found in Japan.
- This similarity can be explained in terms of child rearing style as Japan and Korea have similar child-rearing practices.
