Videotaped Cue for Urge to Drink Alcohol
The urge to drink alcohol can be robustly and reliably induced via actual exposure to a person's preferred alcoholic beverage. Unfortunately, these exposure paradigms are unwieldy for functional magnetic resonance imaging studies. The goal of this study was to examine whether viewing a personalized videotaped cue could induce alcohol craving. The following hypotheses were tested: (1) individualized cue videotapes can reliably elicit the urge to drink alcohol in alcohol-dependent participants and (2) alcohol drinking histories can predict reactivity to cue.
DSM-IV criteria were used to identify an alcohol-dependent group (ADG). Controls included a light-drinking group and a moderate-drinking group. Urge to drink alcohol was assessed at baseline and after each of five in vivo exposure conditions: water (W), alcohol 1 (A1), mood induction (M), alcohol 2 (A2), and relaxation (R). The entire exposure session was videotaped. Each participant's video footage was digitally edited to produce a 17.5-min cue that was presented to the participant 24 to 72 hr later. Ratings of urge to drink alcohol across the five exposure conditions were compared for both the in vivo and the video exposure sessions.
Fourteen participants (five in the light-drinking group, four in the moderate-drinking group, and five in the ADG) completed both sessions. Participants in each group showed differences between neutral cue exposure (W and R) and alcohol-related cue exposure (A1, M, and A2) in both the in vivo cue session (p < 0.002) and the videotape session (p < 0.02). Post hoc comparisons among the groups to alcohol-related cues established that, in both sessions (p(in vivo) = 0.04; p(videotape) = 0.04), the ADG demonstrated the greatest urge to drink.
Alcohol cue reactivity can be reliably induced and assessed in alcohol-dependent participants via personalized videotapes. History of alcohol consumption is positively correlated with the degree of cue reactivity. This study advances our ability to assess alcohol cue reactivity in the absence of alcohol.

- "Ostensibly, the level of cue-reactivity has intrinsic value in addiction studies. For instance, it has been found to be positively correlated with the degree of alcohol consumption (Streeter et al., 2002). Other investigations have found that the reactivity to drugrelated cues correlates with maintenance of drug use and relapse (Juliano and Brandon, 1998). "

ABSTRACT: Abuse liability is thought to possibly be lower in long- than in short-acting opioids because lower peak serum levels may be less likely to induce psychoactive effects.
We compared patient responses to extended-release morphine, hydrocodone plus acetaminophen, and placebo in a randomized, double-blind crossover study using markers of abuse liability. Patients indicated their craving for drugs on 5 visual analog scales (VASs), completed the Addiction Research Center Inventory, and underwent cue reactivity testing. To perform the latter, subjects watched a video intended to produce a positive or a negative affect, after which a vial of medication was or was not presented (the cue) and then indicated their craving for drugs on 5 different VASs (the reactivity).
Differences in Addiction Research Inventory scores were statistically significant but clinically unimportant. Neuropsychological test results were mixed and unrelated to the medications studied. Cue reactivity did not differ among conditions but was uniformly high.
Using several markers of abuse liability, long-acting opioids do not have lower abuse potential than do short-acting opioids or placebo. Although cue reactivity did not differ among the conditions, uniformly high results in these patients suggest that it may have some value as a component of abuse liability testing.

- "First, ceiling effects are known to be especially relevant to craving assessment.16 Substantial evidence demonstrates that exposure to alcohol cues increases the level of alcohol craving in abstinent alcoholics.17,18 Alcoholic patients who rated their craving level near the endpoint of the scale when first exposed to the cue-laden VR environment could have failed to report the actual increase in the level of craving caused by social pressure.

ABSTRACT: This study was conducted to assess the interaction between alcohol cues and social pressure in the induction of alcohol craving.
Fourteen male patients with alcohol dependence and 14 age-matched social drinkers completed a virtual reality coping skill training program composed of four blocks according to the presence of alcohol cues (x2) and social pressure (x2). Before and after each block, the craving levels were measured using a visual analogue scale.
Patients with alcohol dependence reported extremely high levels of craving immediately upon exposure to a virtual environment with alcohol cues, regardless of social pressure. In contrast, the craving levels of social drinkers were influenced by social pressure from virtual avatars.
Our findings imply that an alcohol cue-laden environment should interfere with the ability to use coping skills against social pressure in real-life situations.

ABSTRACT: Stress and conditioned responses to drug cues have been implicated as critical factors in relapse to drug use. In the animal literature, both the conditioned effects of drug-related stimuli and the unconditioned effects of foot-shock stress have been well documented to reinstate extinguished drug-seeking behavior. What has remained largely unexplored, however, is the significance of stimuli conditioned to foot-shock stress for the resumption of drug seeking. Additionally, although relapse is often the result of several risk factors acting in combination, the possibility that interactions among risk factors such as conditioned stress and drug cues may intensify drug-seeking behavior has received little experimental attention.
The purpose of this study was to examine the individual and interactive effects of a stimulus conditioned to foot-shock stress (STRESS CS) and a stimulus conditioned to ethanol reward (EtOH CS) on the reinstatement of ethanol-seeking behavior following extinction.
Male Wistar rats were trained to orally self-administer 10% ethanol on a fixed-ratio 3 schedule of reinforcement. The EtOH CS was established by response-contingently pairing 0.5 s illumination of a white cue light with each reinforced response. The STRESS CS was established by pairing a continuous white noise (70 dB) with intermittent foot shock (10 min; 0.5 mA; 0.5 s on; mean off period of 40 s). Ethanol dependence was induced by an ethanol vapor-inhalation procedure. After ethanol-maintained instrumental responding was extinguished by withholding ethanol and the EtOH CS, reinstatement tests were conducted.
Both exposure to the STRESS CS and response-contingent presentation of the EtOH CS reinstated extinguished responding at the previously active, ethanol-paired lever without further ethanol availability. When response-contingent availability of the EtOH CS was preceded by exposure to the STRESS CS, interactive effects of these stimuli on responding were observed. However, both the individual and interactive effects of the STRESS CS and the EtOH CS reached statistical significance only in rats with a history of ethanol dependence but not in ethanol-nondependent rats.
The results confirm that both conditioned stress and ethanol cues elicit ethanol-seeking behavior and, more importantly, that these stimuli produce interactive effects resulting in an increased ethanol-seeking response. The findings also indicate that susceptibility to ethanol seeking induced by conditioned stress and alcohol cues depends significantly on the history of prior alcohol exposure.
