One hundred and forty-two male and female undergraduates, aged 17–44, completed questionnaire measures of attachment style, alexithymia, self-esteem, positive and negative affectivity, and symptom reporting.
Fearful and preoccupied attachment styles, negative affectivity, and alexithymia were all significantly associated with increased symptom reporting, while the dismissing attachment style was not. Regression analyses showed that the relationship between fearful attachment and symptom reporting was partly, but not fully, mediated by alexithymia and negative affectivity, while that between preoccupied attachment and symptom reporting was mediated mainly by negative affectivity. Low self-esteem was associated with symptom reporting only via its association with negative affectivity.
Fearful and preoccupied attachment styles are both associated with symptom reporting via a negative model of the self and increased negative affectivity, but alexithymia is an additional predictor of symptom reporting in individuals with fearful attachment. This difference is thought to be linked to the model of others developed in early interactions with caregivers.
