Simonelli et al conducted a study in Italy to see if proportions of attachment types still matched prior research. Assessed 76 babies aged 12 months using the SS. They found 50% were secure, and 36% were avoidant. This was a lower rate of secure than in past studies, and higher rate of Type-A. Suggesting this is due to an increasing number of mothers with young children working longer hours with professional childcare. Suggesting attachment trends aren't static, they move with cultural change.
