The Relationship Between Attachment Style and Postformal Thought

The purpose of the present study was to investigate the relationship between attachment styles and postformal thought ability and to test the comparability of three methods of testing for postformal thought. In a sample of 119 participants, postformal thought levels and attachment styles were assessed using postformal thought questionnaires and an attachment style scale. It was predicted that individuals with secure attachment styles would exhibit higher levels of postformal thought ability than individuals with anxious–ambivalent or avoidant attachment styles. It was also predicted that the three postformal tests would have equivalent results. Results indicated that attachment and postformal thought were not related and that the three measures of postformal thought were equivalent. Results are discussed in terms of the relationship between attachment styles and individuals’ abilities to perform complex problem-solving tasks and/or dilemmas.
