Previous evidence has demonstrated a relationship between insecure attachment and the development of emotional dependence towards an individual's partner. However, the possibility that this relationship may be indirect and mediated by individual factors such as difficulties in emotional regulation has not previously been explored. Consequently, the objectives of the present study were to analyze the (i) differences in emotional dependence on an individual's partner and difficulties in emotional regulation capacity according to secure, preoccupied or dismissing attachment style and (ii) mediating role of difficulties in emotional regulation in the relationship between both insecure attachment styles and emotional dependence on an individual's partner. The sample comprised 741 participants ranging in age from 18 to 30 years (M = 21.32, SD = 2.93). The mediations were tested with linear regressions with the macro PROCESS v4.0. The results showed that emotional dependence on a partner and difficulties in emotional regulation were greater among individuals who had developed a dismissing attachment compared those with secure or preoccupied attachment. Likewise, the mediation model confirmed the mediating role of difficulties in the capacity for emotional regulation in the relationship between dismissing attachment and emotional dependence, with rejection of negative or discomfort-generating emotions predominating. The findings provide preliminary evidence that rejection of negative emotional experiences may play an important role in the relationship between insecure dismissing attachment style and emotional dependence on an individual's partner. Consequently, it is recommended that emotional dependence intervention programs include of the management of intolerance to negative emotions.
