The Attachment Style Questionnaire (ASQ) (27) includes 40 items measuring five attachment styles based on the models proposed by Hazan and Shaver (24) and Bartholomew and Horowitz (25): Confidence, Discomfort with Closeness, Relationships as Secondary, Need for Approval, and Preoccupation with Relationships. Each item is evaluated on a 6-point Likert scale (1 = Strongly disagree, 6 = Strongly agree). The Italian version showed an acceptable internal consistency (0.67 < α < 0.74) (65). In the present study, internal consistency was acceptable to good (range of Cronbach's alphas = 0.79–0.85).
