The criteria of Cloninger et al. and von Knorring et al. for subgrouping alcoholics: a comparison in a clinical population

There is increasing evidence that meaningful subgroups of alcoholics may exist. Cloninger et al. and von Knorring et al. have developed criteria to delineate what both call type 1 and type 2 alcoholism. However, when we compared their criteria in a predominantly inpatient sample of male alcoholics, we found large differences between the approaches in identifying type 1 and type 2 alcoholism. Concordance was equally low in a subsample of 34 alcoholics exhibiting antisocial behavior and when subjects were divided by whether the first alcohol‐related problem began before or after 20 years of age. Similar findings emerged when we limited our analyses to primary alcoholics and alcoholics with no other mental disorders.

Cerebrospinal fluid monoamine metabolites in alcoholic patients who attempt suicide.

Reduced cerebrospinal fluid (CSF) levels of the serotonin metabolite 5‐hydroxyindoleacetic acid have been reported to be commonly associated with suicidal behaviour. Alcoholics are known to often manifest suicidal behaviour. Therefore, we compared cerebrospinal fluid levels of monoamine metabolites in alcoholics who had (n= 20) and had not (n= 108) attempted suicide and healthy volunteers (n= 30). There were no significant differences among the 3 groups for CSF levels of either 5‐hydroxyindoleacetic acid, the dopamine metabolite homovanillic acid, norepinephrine, or the norepinephrine metabolite 3‐methoxy‐4‐hydroxy‐phenylglycol.

Substance abuse among subjects screened out from an alcoholism research program

Three hundred and eight subjects were screened over the phone for admission to an inpatient alcohol treatment research unit. Using a structured interview, the prospective patients were asked questions regarding demographics, drinking history, previous treatments, physical health, family history, and a detailed history of past and present substance use. Drug use was studied as regular use versus no use or brief experimental use of five drug categories: cannabinoids, stimulants, sedatives, opiates, and hallucinogens. Fifty-one percent of the men and 48% of the women reported regular use of one or more of the drugs in addition to alcohol. For women, the amount of alcohol intake was positively correlated with use of stimulants (r = .32, p = .001), cannabinoids (r = .24, p = .019), sedatives (r = .30, p = .003), and hallucinogens (r = .30, p = .003). For men, correlations between the amount of alcohol intake and drug use were weaker but significant for stimulants (r = .21, p = .002), opiates (r = .15, p = .028), and hallucinogens (r = .15, p = .029). Women with alcoholic mothers displayed higher alcohol intake than women with nonalcoholic mothers (p = .02) and also showed more frequent use of most drugs. Although men with alcoholic fathers also showed greater alcohol intake compared to men with nonalcoholic fathers, the two groups did not differ in drug use. Younger subjects of both sexes were more likely to use cannabinoids, stimulants, opiates, and hallucinogens. Alcohol and sedative use was relatively constant across all age groups.
