DSM-5 May Change Categories on Substance Use

NEW ORLEANS — Proposed changes to the Diagnostic and Statistical Manual will likely put an end to separate diagnoses of substance “abuse” and “dependence,” distinctions that puzzled even addiction experts, members of the DSM-5 work group on substance-related disorders said at the meeting.

On the basis of discussions held during the meeting, it seems probable that both categories will be subsumed within the general diagnosis, “substance use disorder,” under an expanded DSM addiction section that will include for the first time a behavioral addiction, compulsive gambling.

“Change is good if change can be shown to do more good than bad and can be supported by data,” commented Dr. Marc A. Schuckit during a progress report presented by the APA DSM-5 substance-related disorders work group at the meeting.

If the prime objectives for inclusion in the DSM are making diagnoses that are clear, straightforward, flexible enough to be clinically useful, valid, “moderately” reliable, predictable, and inclusive of “the people who need help,” current substance use categories in the DSM-IV-R admittedly are “out of focus,” said Dr. Schuckit, professor of psychiatry at the University of California, San Diego.

However, the committee wants to be cautious, so that they do not “go from one very useful but not perfectly focused image to another very useful but not very well-focused image,” he said, noting that a rich database has been exceedingly useful in guiding directions for change.

For example, when data from studies representing more than 100,000 subjects were analyzed by the committee, DSM-IV diagnostic criteria for substance dependence were highly reliable and valid, but those for substance abuse were much lower and more variable, said Deborah S. Hasin, Ph.D., professor of clinical public health at Columbia University, New York, a work group committee member, and cochair of the meeting symposium.

The hierarchical relationship between abuse and dependence (with abuse only diagnosed in the absence of dependence) was “often misunderstood, even by people functioning at a very senior level [of the substance abuse research community],” she noted.

Confusion led to widely held, but false beliefs, such as the notion that abuse is a milder disorder than dependence, or that all individuals who are dependent also meet criteria for abuse, Dr. Hasin said.

The extensive data review conformed to what clinicians were seeing, that severity of dependence and of abuse, like other criteria, were intermixed, and that patients could have one of the disorders, or both.

A factor analysis of patient characteristics found “there really wasn't a good rationale to keep abuse and dependence separate,” Dr. Hasin said.

“The evidence seemed quite overwhelming.”

The new DSM, then, will most likely contain 11 potential diagnostic criteria for combined substance use disorder, with severity gauged on the number of criteria met. A patient who meets two criteria would merit a diagnosis of a disorder; a patient who met four or more would be considered to have a severe form of the disorder.

The specific diagnostic criteria for a substance use disorder also will likely change in the DSM-5, with craving being considered a potentially core feature of addiction for the first time.

Likely to be dropped from the list of criteria will be recurrent substance-related legal problems, Dr. Hasin said in an interview.

Nicotine use disorder is highly likely to be included under the substance use disorder umbrella, again on the basis of analysis of characteristics of patients enrolled in many studies that show convergence with other substance use disorders.

The new inclusion of a behavioral disorder—compulsive gambling—might appear as an addiction alongside substance use disorders for the first time, based on years of study, said committee member Dr. Eric Hollander, director of the Compulsive, Impulsive, and Autism Spectrum Disorders Program at Montefiore Medical Center and Albert Einstein College of Medicine, New York.

Currently classified as an impulse control disorder, a large body of evidence now supports compulsive gambling as an addiction, he said in an interview.

None of the working group members disclosed any relevant financial conflicts of interest with regard to the DSM-5.

An analysis found that 'there really wasn't a good rationale to keep abuse and dependence separate.'
