I. V. Zavadskii and the beginnings of behavioral pharmacology: an historical note and translation.

I. V. Zavadskii, who worked in Pavlov's laboratory between 1907 and 1909, performed a study that has many of the characteristics of modern behavioral pharmacology. He studied the effects of alcohol, morphine, cocaine and caffeine on the conditioned salivary reflex. A translation of his paper and some brief comments on his life are presented.     

Test-retest reliability of retrospective self-reports in three populations of alcohol abusers

The reliability of alcohol abusers' retrospective self-reports was evaluated using a time-line follow-back interview technique. Independent groups of male subjects were interviewed in three different treatment settings (outpatient,n=12; inpatient,n=12; residential,n=12) on two separate occasions to assess the test-retest reliability of their self-reports of daily drinking and related events occurring 1 year prior to treatment. Correlational and scatterplot analyses generally showed a high correlation and low discrepancy between the two sets of interview responses for all groups. However, since some population differences were found in the reliability of reports for some variables, further research is needed to delineate the conditions under which reliable and valid retrospective self-reports can be obtained from different populations of alcohol abusers.This research was supported, in part, by Grant No. AA07072 from the National Institute on Alcohol Abuse and Alcoholism to Vanderbilt University.     

Drinking in a patchy environment: the effect of the price of water.

Rats in a laboratory foraging paradigm searched for sequential opportunities to drink in two water patches that differed in the bar-press price of each "sip" (20 licks) of water within a bout of drinking (Experiment 1) or the price and size (10, 20, or 40 licks) of each sip (Experiment 2). Total daily water intake was not affected by these variables. The rats responded faster at the patch where water was more costly. However, they accepted fewer opportunities to drink, and thus had fewer drinking bouts, and drinking bouts were smaller at the more costly patch than at the other patch. This resulted in the rats consuming a smaller proportion of their daily water from the more costly patch. The size of the differences in bout frequency and size between the patches appears to be based on the relative cost of water at the patches. The profitability of each patch was calculated in terms of the return (in milliliters) on either effort (bar presses) or time spent there. Although both measures were correlated with the relative total intake, bout size, and acceptance of opportunities at each patch, the time-based profitability was the better predictor of these intake measures. The rats did not minimize bar-press output; however, their choice between the patches and their bout sizes within patches varied in a way that reduced costs compared to what would have been expended drinking randomly. These data accord well with similar findings for choices among patches of food, suggesting that foraging for water and food occurs on the basis of comparable benefit-cost functions: In each case, the amount consumed is related to the time spent consuming.     

KNOWING WHEN TO SAY WHEN: A SIMPLE ASSESSMENT OF ALCOHOL IMPAIRMENT

The use of writing samples as indices of alcohol impairment was explored. Students at a campus fraternity party wrote a sentence and their signatures before and after consuming alcohol (in beer and mixed drinks). Later, undergraduate and graduate students attempted to discriminate between pre- and postparty handwriting samples. The average percentage of correct discriminations of entrance and exit writing samples was 83.7% for sentences and 67.5% for signatures, and the percentage of correct discriminations increased directly with the blood alcohol concentration of the partier who gave the writing sample. When a partier's blood alcohol concentration reached 0.15, all of the judges accurately discriminated 90% or more of the sentences, and 25 of the 28 judges correctly discriminated at least 80% of the signatures. All of the judges correctly discriminated at least 90% of the 18 sentences written by partiers with a blood alcohol concentration of 0.12 or more. Implications of these findings for reducing the risk of driving while intoxicated are discussed, as well as directions for follow-up research.     

Development of a drinking self-efficacy questionnaire

Self-efficacy has been postulated as a construct of central importance in the acquisition, maintenance, and treatment of addictive behavior. To date research has largely examined the role of outcome expectancies but literature on the relationship of self-efficacy and drinking is still unclear. This paper describes the development and psychometric properties of a Drinking Self-Efficacy Questionnaire (DSEQ). In Study I, 251 students were used to test the factor structure of the DSEQ. Factor analysis of the DSEQ showed three clear factors accounting for 60% of the common variance. These factors can be summarized as self-efficacy in situations characterized by social pressure, opportunistic drinking, and emotional relief. Study II used 138 people from a general community sample and discriminant analyses showed that the DSEQ has good discriminant validity. The findings suggest that the DSEQ has potential for use in research examining the role of drinking self-efficacy in problem drinkers.This paper was partly supported by grants from the NH&MRC to Dr. Oei.     

Congruence couple therapy for alcohol use and gambling disorders with comorbidities (part I): Outcomes from a randomized controlled trial

A nonblinded randomized trial was conducted at two Canadian provincial outpatient addiction clinics that tested the effectiveness of a systemic congruence couple therapy (CCT) versus individual-based treatment-as-usual (TAU) on nine clinical outcomes: (1) primary outcomes—alcohol use and gambling, psychiatric symptoms, and couple adjustment; (2) secondary outcomes—emotion regulation, substance use, depression, post-traumatic stress symptoms, and life stress. Data of primary clients and partners (N = 46) were analyzed longitudinally across baseline, posttreatment (5 months), and follow-up (8 months). Alcohol use disorder (95%) and gambling disorder (5%) were in the severe range at baseline, and co-addiction was 27%. Psychiatric comorbidity was 100%, and 18% of couples were jointly addicted. Between-group comparison favored CCT in primary outcomes with medium-to-large effect sizes (Cohen's h = 0.74–1.44). Secondary outcomes were also significantly stronger for CCT (Cohen's h = 0.27–1.53). Within-group, for all primary outcomes, a significant proportion of symptomatic CCT clients and partners improved, converging with ANOVA results of large effect sizes (0.14–0.29). All secondary outcomes improved significantly in CCT with large effect sizes (0.14–0.50). TAU showed significant within-group improvement in alcohol use, other substance use, and life stress with large effect sizes (0.16–0.40). Primary clients and partners made largely equivalent improvement within CCT and within TAU. Results were triangulated with clients' satisfaction ratings and counselors' reports. Overall, significant within-group effects were detected for CCT both clinically and statistically and between-group difference favored CCT. Future trials are required to validate these promising findings.     

EEG Biofeedback for Addictive Disorders—The State of the Art in 2004

This paper reviews studies of brainwave biofeedback as a therapeutic technique for substance use disorder. This modality is attractive as a medication free, neurophysiologic, and self actualizing treatment for a substance based, brain impaired and self-defeating disorder. Three approaches are described and the literature for each reviewed. Alpha–theta occipital feedback was originally employed to facilitate autosuggestion in hypnagogic states to augment standard therapy approaches in substance abuse treatment programs and appears most suited for chronic treatment resistant alcoholics. Beta augmentation feedback in conjunction with alpha/theta feedback has been employed in mixed substance abuse and stimulant abuse with good results. Individualized brainwave biofeedback based on correcting EEG abnormalities, or based on addressing comorbid conditions is a third approach that has been described, and may be most appropriate where confounding comorbid conditions are present. Although effectiveness in certain hard to treat populations (conventional treatment resistant alcoholics, crack cocaine addicts, cognitively impaired substance abusers) is promising, better-designed controlled studies are needed.     

Shifting Winds: Using Ancestry DNA to Explore Multiracial Individuals’ Patterns of Articulating Racial Identity

This study explored how genotype information affects identification narratives of multiracial individuals. Twenty-one multiracial individuals completed individual interviews before and after receiving a DNA analysis to clarify their genetically based racial ancestry. Based on results, this article proposes patterns of articulating racial identity by multiracial individuals. Four patterns extend evolving research in multiracial identification, namely (1) the individual articulates a monoracial identity; (2) the individual articulates one identity, but this can shift in response to various conditions; (3) the individual articulates an extraracial identity, opting out of traditional categories applied to race; and (4) the person distinguishes traditional categories of race from culture and owns the two identities in different ways. Implications of these findings are discussed. First, adding new ancestry DNA information further muddles the neat categories of race, consistent with the view of race as socially constructed. Second, results emphasize the fluidity of identification for multiracial individuals. Third, DNA information challenges the neat percentages people tend to associate with their backgrounds. Particularly for younger multiracial individuals, there was less of a sense that race was a real thing and more that culture played a big part in how they saw themselves.
