Evaluate the study by Van iJzendoorn and Kroonenberg (1988). (8) Flashcards
Their meta-analysis used secondary data from studies into attachment undertaken by other researchers.
Using secondary data means that they cannot be certain that the studies were conducted reliably by the original researchers, so the data they used may be flawed
The data source search identified suitable studies using strict criterion, such as excluding samples of children over 2 years old.
Strict criterion increases the reliability of the data sources gathered as they could be sure that the studies were comparable
A large sample of 32 studies was used, including 8 different countries which in total involved 1,990 strange situations.
The sample is representative of a large, cross-cultural population which increases the generalisability of the findings.
They planned to use Ainsworth et al (1978) as a baseline sample distribution to measure their findings against.
The overall distribution of attachment in the US studies did not match Ainsworth’s suggestions, therefore there was no baseline measure, limiting cross-cultural comparisons.
