“…As did Breslin and Sobell (1999), the present researchers call on the peer review process to enforce strict reporting methodology, thus ensuring that published articles have suffi cient internal validity and generalizability. One possible method of accomplishing this is journal editors requesting that authors follow CONSORT (Moher et al, 2001) or TREND (Des Jarlais et al, 2004) guidelines, including reporting information on dropout rates and characteristics of participants who dropout.…”

“…Moncrieff and Drummond (1998) surveyed 25 of the most cited alcohol studies and found that external validity was generally poor due to insuffi cient methodology reporting. Breslin and Sobell (1999) summarized that conclusions based on alcohol absorption studies are diffi cult to derive because of the lack of detailed methodology reporting. This defi cit in reporting exists across subdisciplines in psychology.…”

“…One aspect of reporting that has been overlooked in wait-list control studies is dropout rate (e.g., Gutmann et al, 2004). Ironically, some research assessing methodology reporting has omitted dropout rate as a variable of inquiry (e.g., Breslin & Sobell, 1999). Knowledge about dropout rates and differences between dropouts and continuers allow for evaluations of the results and validity of clinical interventions (Sifers et al, 2002), thus they are an important topic for investigation.…”

Reporting practices regarding dropouts in wait-list control studies hold great importance for the ability to replicate, generalize, and draw conclusions from research. This concern is applicable to all psychological research utilizing wait-list controls, regardless of purpose of research (e.g., treatment outcome). The current study assessed the present state of reporting practices in this type of experimental design and discussed the limitations and implications of the insufficient reporting found. 171 articles from psychology journals utilizing wait-list control design were surveyed regarding the reporting of the number of dropouts from the wait-list control and experimental conditions, characteristics and assessment scores of the dropouts, and total dropouts. Variables that are crucial to interpreting research findings are not consistently reported. Additionally, journal impact factor and year of publication were positively correlated with the adequacy of reporting. Consistencies with previous findings were noted, and suggestions for remedying the reporting inadequacies were discussed.

“…Historically, relatively few double-blind studies have reported results from systematic manipulation checks (Breslin & Sobell, 1999; Hughes and Krahn, 1985). The studies that have reported such results have often focused on the placebo condition, during which most participants indicate they received at least some alcohol, experienced an increase in subjective intoxication, or both (e.g., Cronce & Corbin, 2010; Corbin et al, 2008; Giancola, 2006; Greenstein et al, 2010).…”

“…Since alcohol expectancies vary widely and may be important factors in human laboratory studies, the ASP represents a potentially important tool to capture acute responses in persons uninfluenced by recruitment into an “alcohol study” or by the knowledge of exclusively receiving alcohol during laboratory sessions. On the larger issue of assessing blinding, it is suggested that future research investigations address and routinely report on expectancy reduction, effectiveness of blinding, and ascertainment of manipulation checks (Breslin & Sobell, 1999). …”

A fundamental goal of double-blind alcohol challenge studies is to reduce alcohol expectancies, though there is little research on the effectiveness of blinding procedures and their relationship to acute alcohol responses. This study examined social drinkers’ perception of beverage content and related alcohol response during three separate double-blind experimental sessions with placebo, low dose alcohol (0.4 g/kg), and high dose alcohol (0.8 g/kg). Using the Alternative Substance Paradigm, participants (N=182) were informed that the beverage they consumed might contain alcohol, a stimulant, a sedative, or a placebo. At several timepoints, subjective and objective measures were obtained and participants were asked to identify which substance they received. During both placebo and low dose alcohol sessions, 33% and 50% of participants, respectively, did not correctly identify the beverage content; during the high dose alcohol session, 20% did not correctly identify the beverage. While correct and incorrect identifiers at any dose level did not differ on major background variables, drinking characteristics, or psychomotor performance during these sessions, they did differ on self-reported subjective responses, with greater sedation reported by incorrect identifiers in the placebo and high dose conditions. In sum, results suggest that the Alternative Substance Paradigm may be a viable option for alcohol laboratory studies, particularly for repeated sessions in within-subjects designs and in cases where the experimenter wants to reduce expectancy by not revealing a priori that alcohol is being administered.

Background The primary goal of this study was to establish a paradigm for credibly administering placebo alcohol to underage drinkers. We also sought to create a new, valid procedure for establishing placebo alcohol believability. Method Participants were 138 American college students (66.7% female) predominantly (90.0%) under the legal drinking age. Groups of 2–3 participants and one same-sex confederate consumed mixed drinks, purportedly containing alcohol, ad-lib in a naturalistic bar-laboratory for 20 minutes. All beverages, however, were non-alcoholic but we used visual, olfactory, and taste cues to maximize placebo credibility. Also, the confederate made two scripted statements designed to increase the perception of drinking real alcohol. After the drinking portion, participants responded to survey items related to alcohol consumption and intoxication. Next, they were individually debriefed, with open-ended responses used to make a determination of whether the participant was deceived with respect to placebo alcohol. Results All participants estimated consuming some amount of alcohol. However, using a more conservative criteria for estimating alcohol believability based on the debrief, 89.1% of participants were classified as deceived. Deceived participants were much more likely to estimate having a positive Blood Alcohol Content, and to say their current level of intoxication was typical given the amount of alcohol consumed than non-deceived participants. Discussion Credibly administering placebo alcohol to underage drinkers is possible. This approach carries great potential for future laboratory work. In addition, the methodology used here to classify participants as deceived or not deceived appears valid based on self-reported BAC estimation and intoxication levels.
