Psychometric properties of the Manchester Child Attachment Story Task: An Italian multicentre study

The paper describes a multicentre study of the psychometric properties of the Manchester Child Attachment Story Task in a sample of 230 Italian children aged 4 to 8 years. The task’s internal consistency and inter-rater reliability were investigated; in addition, multiple discriminant analysis was used to explore the contribution of individual coding system scale scores to overall categorical attachment classification. The instrument showed acceptable psychometric properties, especially with respect to Disorganization and Coherence scales. However, our results also suggest that some subscales of the coding system could be modified in order to improve reliability. The implications of our results for future research and further test validation are discussed.
