In 1955, the American Medical Association (AMA) officially recognized alcoholism as a disease, marking a turning point in how addiction was treated and understood. This recognition opened the door to exploring the psychological impact on families and the intergenerational transmission of dysfunction. [1]

In 1969, Canadian researcher Margaret Cork published The Forgotten Children, drawing attention to the struggles faced not only by people with alcohol dependency, but by their children as well. [2]

During the 1970s, the term "Adult Children of Alcoholics" began to emerge among clinicians and patients alike. In 1983, educator Janet G. Woititz published Adult Children of Alcoholics, which brought the concept into mainstream awareness. [3]

Originally applied to families affected by alcoholism, the concept gradually expanded to include any household marked by abuse, excessive pressure, or other forms of dysfunction — ultimately encompassing what we now call dysfunctional families more broadly.

John Bradshaw's 1988 work further detailed the emotional consequences experienced by children raised in such environments, helping to solidify ACoA theory in popular and clinical discourse. [4]

ACoA individuals are often characterized by emotional suppression, excessive self-responsibility, and avoidance of close relationships — patterns that frequently persist into adulthood.

From the 1980s through the 1990s, support for ACoA individuals grew significantly, with increases in psychotherapy options and peer support groups. Today, the ACoA framework remains an important focus in psychology and counseling.

The following studies were reviewed in developing the ACoA scale used in this assessment.

· Woititz (1983) [3]
In Adult Children of Alcoholics, Woititz identified key traits common among ACoA individuals, including emotional suppression, excessive self-responsibility, and avoidance of close relationships.

· Bradshaw (1988) [4]
Bradshaw examined the far-reaching effects of dysfunctional family environments, identifying behavioral patterns such as codependency, loss of personal agency, and denial as characteristic of these households.

· Sasano et al. (1998) [5]
In researching the relationship between dysfunctional families and ACoA tendencies, Sasano and colleagues developed a single-factor ACoA scale, which informed our approach.

Licensed psychologists, clinical psychologists, and graduate-level psychology professionals conducted a series of brainstorming sessions. Items were then grouped using the KJ method and refined through expert review. The final scale comprises six factors with four questions each, as listed below.

• 【Family Dysfunction】
• Our home was not a place where emotions could be freely expressed
• Someone in the family had emotional outbursts
• A family member was controlling or domineering
• Home did not feel like a safe or secure place



• 【Persistent Memory】
• My family's attitudes from childhood still stay with me today
• My relationship with my family continues to be a source of emotional burden
• I pushed myself to meet my family's expectations
• I made decisions based on how my family might react



• 【Unstable Self-Worth】
• I often feel that I lack value as a person
• I am strongly influenced by how others evaluate me
• I hold back from taking action because I lack confidence in myself
• I keep blaming myself even for small mistakes



• 【Emotional Suppression】
• I find it hard to express my true feelings honestly
• I tend to go along with others rather than saying what I really think
• I keep holding back sadness and anger
• I suppress my emotions and deal with them internally



• 【Difficulty in Relationships】
• I feel a sense of distance even from people I am close to
• I tend to avoid getting deeply involved with others
• I am overly conscious of how others see me
• Even when I trust someone, I easily feel that they will betray me



• 【Excessive Responsibility】
• I try to solve other people's problems as if they were my own
• I feel like I have to be the one to work hard
• I put others first even at the expense of myself
• I hesitate to ask others for help
