Problematic patterns of romantic attachment are not all the same, according to a new systematic review published in Archives of Sexual Behavior. Researchers found that manic love, emotional dependence, and love addiction each have distinct psychological profiles, suggesting they should be studied and treated as separate conditions rather than being grouped together.
Most romantic relationships contribute positively to people’s well-being. However, for some individuals, romantic relationships become marked by obsession, excessive dependence, or compulsive attachment that interferes with daily life. Scientists have used different names for these behaviors—including manic love, emotional dependence, and love addiction—but there has been little agreement about whether they describe the same or different problems.
The researchers set out to clarify this by reviewing decades of research and comparing the psychological characteristics associated with each form of problematic love behavior. They also wanted to determine whether these patterns differed depending on the gender composition of study samples.
Led by Magdalena Sánchez-Fernández, a researcher at the University of Cádiz in Spain, the team searched four major scientific databases and identified 102 eligible studies. The final sample included 55 studies on manic love, 34 on emotional dependence, and 13 on love addiction. Across the studies, sample sizes ranged from 63 to 3,375 participants, with the proportion of women varying from 0% to 94.2%.
The team discovered that each type of problematic love behavior was associated with a different pattern of psychological characteristics. For example, relationship satisfaction exhibited opposite patterns of association across the domains. Higher relationship satisfaction was significantly associated with emotional dependence, but lower relationship satisfaction was significantly associated with manic love attitudes.
Additionally, anxious insecure attachment was significantly associated with love addiction but was not a significant meta-analytic correlate of emotional dependence. These findings provide empirical support for the hypothesis that these behaviors are distinct psychological entities that must be investigated independently.
Among the three types of problematic love behaviors, emotional dependence was linked to the widest range of psychological and relationship factors. Emotional dependence was tied to alcohol and substance use, behavioral addictions, violence (both received and perpetrated), and relationship satisfaction. Low self-esteem emerged as a common feature of both emotional dependence and manic love, while behavioral addictions were linked to both emotional dependence and love addiction.
The researchers also identified notable gender differences. The relationship between manic love and jealousy, as well as between manic love and lower relationship satisfaction, was stronger in studies involving higher proportions of women. By contrast, the association between love addiction and anxious attachment was stronger in studies with more men. These findings indicate that gender may influence how problematic relationship behaviors develop or are expressed.
Sánchez-Fernández and colleagues concluded, “The ultimate intention of this study is to move beyond the pathologization of problematic romantic behaviors. We align with authors who argue that problematic behaviors are not clinical pathologies or syndromes but rather stem from maladaptive cognitions, behaviors, and coping strategies that result in negative daily life consequences.”
The authors note several important limitations. For instance, nearly every study included in the review used a cross-sectional design, meaning it is impossible to determine whether the psychological factors caused problematic love behaviors or resulted from them. The research also heavily relied on studies from the United States, Spain, and Italy, and the findings may not translate across all cultures or non-monogamous relationship styles.
