<p>A relationship breakup has emotional, behavioral and social consequences that affect people who decided to terminate the relationship (agents) and those who were abandoned (passives). The goal of this study is the validation in a Mexican sample (n = 1106) a scale to measure breakup consequences in the actors of the romantic dissolution -passives and agents- and explore the differences in breakup consequences in relation with attachment styles. A final scale was obtained with 25 items distributed across 4 factors with good psychometric properties (Cronbach’s Alpha=0.94, 62.20% of the total explained variance). Regarding the second goal of this study, in the passive participants was identified the predominance of anxious and safe attachment styles; whereas in the agents the avoidant and safe attachment styles were more noticeable.</p>
