MANY POPULAR assumptions about children of alcoholics are being questioned by new research, posing a challenge to the hugely popular therapy movement directed at them and other "adult children" of problem families.
Although proponents of the movement say they have scientific support for their views, critics are unconvinced.
The therapy is based on the idea that the childhood experiences of "adult children of alcoholics," or "ACOAs," have left them with unique emotional patterns and problems.
These include, for example, feeling different from others, putting up a false front, being reluctant to stand up for themselves and failing to enjoy life as much as they would like.
But a new study has found that most people feel this way. The researchers charge that these and other basic beliefs of the ACOA movement are so vague or true of so many people that almost everyone identifies with them.
In short, they are so universal that they are devoid of therapeutic usefulness. These researchers say these statements, which seem more specific than they are, are similar to those used by fortune tellers or astrologers; they call them "Barnum statements," after the huckster P.T. Barnum.
Proponents of the movement concede that more research is needed on the adult children of alcoholics. But they say scientists studying the transmission of alcoholism from generation to generation have ignored the clinical experience of therapists who treat children of alcoholics.
"Only recently has there begun to be research directed by the ACOA outlook," said Dr. Claudia Black, a psychologist who is director of a treatment center for children of alcoholics in Cerritos, Calif.
The proponents cite positive results from a new study, one of the few designed specifically to test a major idea of the movement, that children of alcoholics are drawn to help partners who exploit them.
"The reason there's not yet enough research on adult children of alcoholics is that academics have focused on things like the role of genetics in alcoholism, or on the 20 percent of children of alcoholics who have the worst problems and so can be easily studied because they are in a hospital or in jail," said Dr. Black, who has written several books on the subject.
But many researchers remain skeptical. "Most of the beliefs popularized by the ACOA movement have never been tested scientifically," said Dr. Kenneth Sher, a psychologist at the University of Missouri, who is the author of "Children of Alcoholics: A Critical Appraisal of Theory and Research," published last year by the University of Chicago Press.
It was Dr. Sher, with Mary Beth Logue, a graduate student, who conducted a recent study to test whether basic tenets of the ACOA movement owed their appeal to their being Barnum statements.
First they combed the popular literature to identify key propositions about the traits of children of alcoholics. They then used an experimental ruse to test whether those traits would be seen as better fitting themselves by 112 sons and daughters of alcoholics than by 112 men and women whose parents were not alcoholics.
The participants, all college students, were recruited for what they were told was the validation of a newly developed personality test. After responding to questions in the test, the students were shown a personality profile that was purportedly based on their answers.
The profiles were actually either from popular descriptions of the traits of children of alcoholics or statements taken from previous research on the Barnum effect, such as, "You have some personality weaknesses."
About two-thirds of the men and women said the descriptions fit them well, regardless of whether the statements were from the list of traits of adult children of alcoholics or from the known Barnum statements. Results of the study will be published later this year in Professional Psychology.
"A lot of people resonate with the popular descriptions of children of alcoholics because they are universal truths or vague enough," Dr. Sher said. But, he added, because these personality traits do not distinguish children of alcoholics from most other people, they have little use in making diagnoses or specifying what kind of treatment would be most effective.
"It's a legitimate concern that some clinical claims about adult children of alcoholics are so broad they seem to apply to everyone," said Dr. Timmen Cermak, a psychiatrist at Genesis, a San Francisco treatment center that specializes in the problems of adult children of alcoholics.
"But whenever there is a new clinicalentity, like child abuse, you have to focus on the most general truths to raise public awareness; then you can start looking at the complexities," added Dr. Cermak, whose book, "Evaluating and Treating Adult Children of Alcoholics" (Johnson Institute), was published last year.
