Insecure Attachment and Subclinical Depression, Anxiety, and Stress: A Three-Dimensional Model of Personality Self-Regulation As a Mediator.

Although the effects of insecure attachment on vulnerability, incidence, and developing mental disorders have been confirmed by many studies, the mechanism of this effect is still unknown. Therefore, the main aim of this study was to investigate the mediating and moderating role of the three-dimensional model of personality self-regulation in the relationship between insecure attachment and subclinical depression, anxiety, and stress. Four hundred Iranian students at Shiraz University were recruited and completed the following scales: the Revised Adult Attachment, Depression Anxiety Stress, Integrative Self-Knowledge, Mindful Attention Awareness, Self-Control, and Self-Compassion. Results showed that there was a moderate correlation among all the variables under study in the expected directions. Multiple mediating models analyses indicated that regarding the relationship between insecure attachment and depression, the components of integrative self-knowledge, self-control, and self-compassion functioned as mediators. However, regarding the relationship between insecure attachment and anxiety and stress, the components of integrative self-knowledge, mindfulness, and self-compassion relatively functioned as mediators. Further, our results showed that only mindfulness and self-compassion were identified as moderators in the relationship between insecure attachment and depression. It is concluded that insecure attachment may cause psychological damage due to deficiency in the components of the three-dimensional model of personality self-regulation, and that mindfulness and self-compassion may play a protective role in the relationship between insecure attachment and depression.
