Attachment theory is considered an explanatory framework for understanding non-suicidal self-injury. Despite theoretical postulations, few studies have examined links between romantic attachment and its interconnected systems (the caregiving and sexual systems) and self-injury. This study investigated whether self-injurious thoughts and behaviours could be predicted by the functioning of the three systems. Two-hundred and sixty-three young adults participated in the study. Results revealed that participants endorsing self-injurious thoughts experience greater attachment anxiety and avoidance, controlling and compulsive romantic caregiving behaviours, and lower sexual satisfaction than participants with no thoughts. Conversely, findings indicate that the behavioural systems did not predict self-injurious behaviours. Such findings suggest that dimensions of the three interrelated behavioural systems hold unique roles in understanding young adult self-injurious thoughts, and that the constructs that predict self-injurious thoughts may differ from those that predict self-injurious behaviours.

This study compares levels of couple agreement about positive and satisfying features of their relationship as reported by a remarried sample (n = 70) couples and a more general sample of couples largely in their first marriage or committed de facto relationship (n = 100 couples). The ENRICH inventory (Olson et al., 1982) was used with the general sample and the ENRICH-Anew inventory (Schultz & Schultz, 1987) was used for the remarried sample, thereby providing the measures of positive couple agreement, which can in turn serve as indicators for strengthening family relationships. There were no statistically significant differences between the two samples, indicating commonalities in stresses and strengths experienced by the two samples. However, there are suggestions in the data that issues related to children and parenting were subject to lower levels of agreement for the remarried couples. The comparison couples produced lower levels of agreement in the areas of conflict resolution and relating to partner's family and friends.
