Attachment narratives are increasingly used as a diagnostic tool in the therapeutic work with children in middle childhood. This, however, demands extensive procedures to ensure its adequate analysis and reliability.Thus, a new diagnostic instrument has been developed. It is a short version of the coding procedure used in the German Attachment Story Completion Task (GASCT) andmakes use of the idea of traffic lights. It can be understood quite intuitively and can be applied time-economically in practice. Instead of a qualitative classification into four attachment groups it results in a five-graded clinical assessment of the child's attachment security towards his or her attachment figures. This can be compared to the attachment security score of the GASCT. Psychometric qualities of the "Attachment Story Completion Light" were analyzed in a sample of 50 patients of a child and adolescent psychiatric hospital aged between four and eight years. Reliability was high, validity of the new instrument was also satisfying, regarding it's association with the original GASCT. For applying the new attachment screening tool a supervised training is required.The tool will enable practitioners to better recognize strengths and difficulties in the attachment representations of children and to plan adequate individualized therapy. As a rating identifying developmental risks, the instrument can help to clarify therapeutic procedures as well as service delivery for child and family.
