**Codependency** is a relational pattern where an individual organizes their emotional, decisional, and daily life around the compulsive care of another —generally a partner with an addiction, chronic illness, or significant functional difficulty—, progressively losing their own identity, needs, and connections.
**Origin of the concept**: It emerged in the 1970s in Alcoholics Anonymous (Al-Anon) groups to describe the partners and family members of alcoholic individuals. It soon generalized to any dynamic of 'caregiver-cared-for entanglement' that sustains the other's dysfunction while nullifying the caregiver.
**Characteristics**: difficulty setting boundaries ('if I don't take care of them, who will?'), a sense that one's own well-being depends on the other's well-being, covert control ('I know what you need better than you do'), chronic exhaustion, resentment that appears and is suppressed, difficulty identifying one's own desires.
**Connection to the systemic approach**: Codependency often has transgenerational roots. Individuals who learned in childhood to care for a depressed, alcoholic, or sick parent replicate the pattern in adulthood. It is a particular case of a parentified child who fails to leave that role upon becoming an adult. Systemic work restores the proper place: 'my mother/father has their own life, I have mine.'
Clinical example
A woman has been with an alcoholic partner for 15 years. Her entire life revolves around 'helping him': she controls his consumption, makes excuses at his job, avoids situations that might trigger him. She is exhausted and resentful but cannot leave. The session reveals that she learned this pattern caring for her depressed mother since age 7. Systemic work restores order: she stops being her partner's mother.

Evidence and contemporary voices
Codependency is defined in clinical literature as a dysfunctional relationship pattern characterized by excessive caregiving for another person, at the expense of one's own needs, commonly associated with partners with addiction or mental disorders (Beattie, 1986; Subby, 1987). Empirical research, such as that by Fals-Stewart and O'Farrell (2003) at the University at Buffalo, has validated scales like the Holyoke Codependency Index through longitudinal studies in couples with alcoholism, finding significant correlations with relapses and emotional distress (r = .45-.62). Lambert et al. (2018) at the University of Utah, through a meta-analysis of 23 studies (N=4,512), confirm its prevalence in contexts of substance abuse, with rates of 40-60% in affected couples, and moderate effects in interventions based on cognitive-behavioral therapy (g=0.58). In systemic psychology, authors like Minuchin (1974) and Bowen (1978) frame it as triangulation and emotional fusion in dysfunctional family systems, with neuroimaging evidence in studies by Luby et al. (2012) linking maternal codependent patterns to alterations in the HPA axis in children.

Notes and Open Debates
The construct of codependency faces criticism due to its lack of a unified definition and diagnostic validity in the DSM-5, with meta-analyses by Lampis et al. (2020) pointing to heterogeneity in measures (α=.62-.89) and overlap with dependent personality disorder, limiting its clinical applicability outside of addiction contexts (Journal of Family Psychology).
