Abstract
BACKGROUND AND AIMS Craving is central in the definition of addictive disorders because of its diagnostic and prognostic value. Its measurement is essential in clinical practice. Previous reviews provided a better overview of existing instruments; however, they do not consider emerging substances and behaviors such as sexual addictions. Our objectives were threefold: (1) to provide a systematic review of craving assessment instruments and their psychometric characteristics within a transdiagnostic approach, (2) to highlight and map their conceptual relationships and (3) to identify potential sexual craving assessment instruments. METHODS The review was conducted using Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) methodology. The PubMed, Embase, PsychInfo and Cochrane/Central databases were searched for publications that met the following inclusion criterion: validation studies of craving assessment instruments, regardless of target substance or behavior. The original search identified 4561 references and included 147 articles. Each selected study was a peer-reviewed publication. RESULTS This review provides a synthesis of the psychometric properties of 36 original instruments and identified 93 variations of these instruments (e.g. translations). We were able to highlight five transdiagnostic families of instruments, each corresponding to a conceptual model. Only one instrument for assessing craving in the domain of compulsive sexual behavior, focused on pornography use, has been identified: the Pornography Craving Questionnaire. CONCLUSION This review mapped all craving assessment instruments from a transdiagnostic perspective, finding 36 original instruments and 93 variations. The evolution of instruments to measure craving mirrors the evolution of the concept of craving which has progressively integrated cognitive, conditioning and sensory dimensions, and attests to the importance of the context of assessment. Development of an instrument to measure 'sexual craving' is needed and could be based on the data from our review.

A meta-analysis of craving studies in schizophrenia spectrum disorders. Schizophr Res 2020; 222:49-57.

Abstract
OBJECTIVE DSM-5 Substance Use Disorders (SUD) are frequent and debilitating comorbidities displayed by patients with schizophrenia spectrum disorders (SZ). One crucial feature of SUD is drug craving, an intense desire to consume a substance, commonly divided into reward and relief dimensions. Here, we conducted a meta-analysis of studies investigating craving in individuals with both SUD and SZ in order to examine whether these patients exhibit a distinct pattern of craving as compared to patients with SUD without SZ. METHOD Meta-analysis based on the PRISMA guidelines. RESULTS Sixteen relevant publications were identified by a systematic search of databases, which included 1219 individuals (589 SUD-SZ and 630 SUD-without-SZ). Of the 16 studies, 11 focused on tobacco, 3 on cannabis and 2 on cocaine. When considered across all studies, SUD-SZ had significantly higher scores than SUD-without-SZ for global craving with medium effect size (knumber of studies = 16, Zr = 0.20 [0.15, 0.26], equivalent d = 0.41, P < 0.001). Discrete patterns emerged for reward (k = 7, Zr = 0.10 [0.02, 0.17], equivalent d = 0.20, P < 0.05) and relief (k = 7, Zr = 0.25 [0.17, 0.33], d = 0.52, P < 0.001) craving, and the direct comparison revealed a significantly greater effect for relief than reward (χ2(1) = 7.40 P = 0.007). CONCLUSION These results suggest that SUD-SZ cases experience higher craving, more specifically for relief, in comparison to patients with SUD-without-SZ. These clinical findings can foster the development of tailored addiction therapies for this specific comorbid population.

Efficacy, acceptability and tolerability of antipsychotics in patients with schizophrenia and comorbid substance use. A systematic review and meta-analysis. Eur Neuropsychopharmacol 2019; 29:32-45.

Abstract
Patients with schizophrenia and substance related comorbidity or substance induced psychotic disorder are difficult to treat. Although the prevalence of a comorbid substance use is approximately 40% in schizophrenia, such patients are usually excluded from clinical trials. We therefore performed a random-effects meta-analysis of all randomized controlled antipsychotic drug trials in this patient subgroup. We searched multiple databases up to May, 2018. The primary outcome was the reduction of substance user; secondary outcomes were craving, mean reduction of substance use, overall change in schizophrenia symptoms, positive and negative symptoms, response, dropouts, quality of life, social functioning, weight gain, sedation, prolactin, extrapyramidal side effects and use of antiparkinsonian medication. We identified 27 references from 19 RCTs published from 1999 to March 2017 including 1742 participants. The most frequent types of substance abuse were cannabis (8 studies) and cocaine (6 studies) use/dependence. Clozapine was superior to other antipsychotics for reduction of substance use and risperidone to olanzapine for craving. Olanzapine, clozapine and risperidone showed superiority for symptom reduction compared to some other drugs. When reported, results of side-effects followed known patterns. The evidence-base is considerable (19 RCTs), however, firm conclusions cannot be drawn due to small sample sizes of individual studies and insufficient reporting.

Abstract
BACKGROUND Cocaine dependence is a public health problem characterised by recidivism and a host of medical and psychosocial complications. Cocaine dependence remains a disorder for which no pharmacological treatment of proven efficacy exists. OBJECTIVES To evaluate the efficacy and the acceptability of antipsychotic medications for cocaine dependence. SEARCH METHODS This review is an update of a previous Cochrane review published in 2007. We searched up to 15 July 2015 in Cochrane Drugs and Alcohol Group Specialised Register (searched in CRSLive); the Cochrane Library (including the Cochrane Central Register of Controlled Trials (CENTRAL); the Database of Abstracts of Reviews of Effects (DARE)); PubMed; EMBASE; CINAHL and Web of Science. All searches included non-English language literature. SELECTION CRITERIA All randomised controlled trials and controlled clinical trials with focus on the use of any antipsychotic medication for the treatment of cocaine dependence. DATA COLLECTION AND ANALYSIS We used standard methodological procedures expected by Cochrane. MAIN RESULTS We included 14 studies (719 participants). The antipsychotic drugs studied were risperidone, olanzapine, quetiapine, lamotrigine, aripiprazol, haloperidol and reserpine. Comparing any antipsychotic drugs versus placebo, we found that antipsychotics reduced dropout: eight studies, 397 participants, risk ratio (RR) 0.75 (95% confidence interval (CI) 0.57 to 0.97), moderate quality of evidence. We found no significant differences for any of the other primary outcomes considered: number of participants using cocaine during the treatment, two studies, 91 participants: RR 1.02 (95% CI 0.65 to 1.62); continuous abstinence, three studies, 139 participants: RR 1.30 (95% CI 0.73 to 2.32); side effects, six studies, 291 participants: RR 1.01 (95% CI 0.93 to 1.10); and craving, four studies, 240 participants: RR 0.13 (-1.08 to 1.35). For all of these comparisons we rated the quality of evidence as low.Comparisons of single drug versus placebo or versus another drug are conducted in few trials with small sample sizes, limiting the reliability of the results. Among these comparisons, only quetiapine seemed to outperform placebo in reducing cocaine use, measured by grams per week: mean difference (MD) -0.54 (95% CI -0.92 to -0.16), by US dollars spent per week: MD -53.80 (95% CI -97.85 to -9.75), and by craving: MD -1.23 (95% CI -2.19 to -0.27), but results came from one study with 60 participants.The major limitations of the studies were the high risk of attrition bias (40% of the included studies) and low quality of reporting, mainly for the risk of selection bias, performance and detection bias, that we rated as being at unclear risk for 75% to 80% of the studies. Furthermore, most of the included studies did not report results on important outcomes such as side effects, or use of cocaine during treatment and craving, which prevented the possibility of including them in statistical synthesis. AUTHORS' CONCLUSIONS At present, there is no evidence supporting the clinical use of antipsychotic medications in the treatment of cocaine dependence, although results come from only 14 trials, with small sample sizes and moderate to low quality of evidence.

Abstract
BACKGROUND The Obsessive Compulsive Drug Use Scale (OCDUS) and the Desires for Drug Questionnaire (DDQ) are two frequently used drug craving questionnaires. Although both heroin and cocaine versions of the questionnaires exist, only the heroin versions have been psychometrically evaluated. The present study was conducted to evaluate the psychometric qualities of the cocaine versions of the OCDUS (OCDUS-C) and DDQ (DDQ-C). METHODS Cocaine-dependent inpatients (n = 101) completed both scales as well as a Visual Analogue Craving Scale (VACS), an alternative, one-item index for assessing momentary craving. We examined the reliability (internal consistency), construct validity (factor structure), and concurrent validity (correlations among both questionnaires, the VACS, and indicators of severity of dependence). A subsample also completed the OCDUS-C and DDQ-C for a second time, one week after the initial administration to obtain a preliminary investigation of the test-retest reliability. RESULTS In general, both questionnaires displayed good internal consistency, test-retest reliability, and concurrent validity. Further, the construct validity of both the DDQ and OCDUS was demonstrated by means of confirmatory factor analyses showing the expected three-factor models. CONCLUSION Our results indicate that the OCDUS and DDQ for cocaine are both easy to administer and reliable instruments to assist the clinical practitioner or researcher to measure craving in cocaine dependent subjects. Moreover, the factor structure for the cocaine versions were similar to the heroin versions, indicating the OCDUS and the DDQ can be reliably used to measure craving for both substances, enabling a direct comparison between heroin and cocaine craving.

Abstract
This study aimed to develop a scale (Obsessive-Compulsive Cocaine Scale [OCCS]) for measuring cocaine craving based on the Obsessive Compulsive Drinking Scale (OCDS). We tested the scale on 116 French-speaking cocaine users. The scale was reliable (Cronbach's α= 0.93). It was significantly correlated with a visual analogue scale of craving (r = 0.641, p < .001) and discriminated between cocaine-dependant subjects (score 36 ± 11) and abusers (score 17 ± 9, p < .001). Prospective tests on a sample of 20 subjects showed that the OCCS score changed over 3 weeks of treatment and was significantly correlated with the visual analogue scale of craving (r = 0.492, p = .038). Principal component analysis identified three factors: resistance, intensity, and interference. The OCCS questionnaire could be used to repeatedly assess cocaine craving in prospective studies in cocaine addicts. (Am J Addict 2012;00:1-7).

Abstract
Measures of subjective drug craving - often defined as the experience of an intense or compelling urge or desire - may be used to predict relapse, evaluate psychological and pharmacological treatments, and test theories of addiction and craving. This review summarizes both direct self-report questionnaires and indirect behavioral, physiological and reaction time measures designed to assess craving for alcohol, amphetamines, cocaine, heroin, marijuana, and tobacco. Multi-item questionnaires have typically been based on one of four underlying conceptualizations of addiction or craving (obsessive-compulsive, approach-avoidance, multi-dimensional, intensity-frequency-duration). Most multi-item self-report questionnaires have high internal consistency, correlate significantly with single-item craving ratings, and demonstrate several aspects of construct validity. Proposed indirect or proxy measures of craving include drug dreams, speed of drug consumption, willingness to work for drug access, selection of monetary rewards over drug access, psychophysiological reactivity, and attentional bias to drug cues. These proxy measures of craving are presumed to obviate self-report biases, to be less subject to conscious self-control, and to reflect craving which the person may not be able to articulate; however, there have been too few demonstrations of their validity and they have too many practical limitations to supplant self-report measures of craving at this time.

Abstract
INTRODUCTION Although craving plays an important role in relapse, there are few brief, valid and reliable instruments to measure the desire to use cocaine in routine clinical practice. The 45-item Cocaine Craving Questionnaire-Now (CCQ-Now) is widely used in research, but its length makes its use in everyday clinical work relatively impractical. This study sought to determine the psychometric properties of the CCQ-Brief, a measure composed of 10 items from the CCQ-Now, in treatment-seeking cocaine abusers. METHOD Subjects with cocaine abuse or dependence (n=247) completed the CCQ-Brief, the CCQ-Now, the Voris Cocaine Craving Scale, the Beck Depression Inventory-II, the Beck Anxiety Inventory, and the Addiction Severity Index. RESULTS The CCQ-Brief was significantly correlated with the CCQ-Now (r=.85, p<.01), the CCQ-Now with the items in common with the CCQ-Brief removed (r=.78, p<.01), all four subscales of the VCCS (craving intensity: r=.47, p<.01; mood: r=.27, p<.01; energy: r=.30, p<.01; sick feelings: r=.28, p<.01), the BDI-II (r=.39, p<.01), the BAI (r=.35, p<.01) and recent drug use (r=.26, p<.01). The internal consistency of the CCQ-Brief was strong (alpha=.90). DISCUSSION The CCQ-Brief is a valid and reliable instrument that can be easily administered as a measure of current cocaine craving.

Abstract
OBJECTIVE Although a growing body of research suggests that atypical neuroleptic medications are efficacious in the treatment of cocaine addiction among individuals with schizophrenia, more rigorously controlled trials are needed. To extend this research, we performed a 6-week double-blind study comparing olanzapine to haloperidol with the primary objective of reducing cue-elicited cocaine craving and the secondary aims of decreasing substance use, improving psychiatric symptoms, and determining an effect size for future studies. METHODS Thirty-one subjects with cocaine dependence and schizophrenia were randomized to olanzapine or haloperidol, underwent a cue-exposure procedure, and completed psychiatric and substance abuse ratings. RESULTS Individuals in the olanzapine group who completed the study had a significant reduction on the energy subscale of the Voris Cocaine Craving Scale at study completion compared with individuals in the haloperidol group. The olanzapine-treated group also had lower, but not statistically significant, PANSS General Psychopathology Subscale scores and fewer positive urine toxicology screens compared with those in the haloperidol group. CONCLUSION This small, but rigorously controlled, pilot trial provides additional evidence for the use of atypical antipsychotics for the treatment of individuals with co-occurring schizophrenia and cocaine dependence. Reductions in craving were associated with medium to large effect sizes.

Abstract
Comorbid cocaine abuse adversely affects clinical outcomes in schizophrenia. Using a prospective, randomized, parallel group design (N = 24), we tested the hypothesis that patients with schizophrenia treated with olanzapine have reduced cocaine craving and abuse compared with those treated with haloperidol. In addition, we examined whether this differential effect correlated with reductions in extrapyramidal symptoms, positive and negative symptoms, and/or depression. There were no significant differences overall in proportions of positive drug screens between treatment groups; no differences in positive, negative, or depressive symptoms; and few differences between treatment conditions in extrapyramidal symptoms. However, craving for cocaine was rated significantly lower by patients treated with haloperidol compared with patients treated with olanzapine. Important study limitations include a small sample size and high attrition rates. Larger controlled studies are necessary to determine optimal antipsychotic therapy for patients with schizophrenia and comorbid cocaine abuse.

Abstract
Cocaine craving has been implicated as a major factor underlying addiction and drug relapse. From a cognitive viewpoint, craving may reflect, in part, attentional processing biased in favor of drug-related cues and stimuli. Schizophrenic individuals (SZ), however, abuse cocaine in high numbers but typically manifest baseline cognitive deficits that impair their ability to selectively allocate their attentional resources. In this study, we examined the relationship between attentional bias and craving in patients with cocaine dependence (COC; n=20), schizophrenic patients comorbid for cocaine dependence (COC+SZ; n=23), as well as two other comparison groups using a modified version of the Stroop test to include cocaine-relevant words. Results revealed that only the COC patients demonstrated Stroop interference on the cocaine-related words. Moreover, COC patients' attentional processing biases were significantly associated with their cocaine craving severity ratings. COC+SZ patients, in contrast, did not demonstrate Stroop interference and manifested significantly fewer craving symptoms than their COC counterparts. These results suggest that COC+SZ patients' inability to selectively encode their drug-use experience may limit and shape their subjective experience of craving cocaine and motivation for cocaine use.

Abstract
Cocaine use causes an initial increase in dopamine and serotonin neurotransmission that is largely responsible for the pleasurable and reinforcing effects of the drug. Dysregulation of these neurotransmitters during withdrawal plays an important role in craving. Recent research has focused on the use of dopamine and serotonin antagonists early in recovery to reduce cocaine craving in both schizophrenic and non-schizophrenic cocaine dependent patients. This 2-week, double blind, placebo-controlled study compared risperidone vs. placebo in reducing cue-elicited cocaine craving. Thirty-four subjects with cocaine dependence were randomized to either risperidone or a placebo and underwent a weekly cue-exposure procedure. Although both groups had a reduction in craving over time, there were no significant differences among those treated with risperidone (n=19) compared to those taking a placebo (n=16) on the four craving dimensions. The results do not support the hypothesis that risperidone reduces cocaine craving among non-schizophrenic cocaine-dependent individuals.

Abstract
BACKGROUND We previously reported that cocaine-dependent patients with a reduced blue cone b wave electroretinogram (ERG) responses had significantly more cue-elicited craving. METHODS A new series of 21 recently withdrawn cocaine-dependent patients completed a craving questionnaire at baseline and following cue exposure; an ERG was also performed. RESULTS Cocaine-dependent patients with a blunted ERG blue cone response (<0.5 microV) showed greater increases in craving following cue exposure. When subjects were included from our preliminary study (N = 14), these differences became highly significant. CONCLUSIONS Patients with a reduced ERG response may represent a subgroup more vulnerable to cocaine craving and future relapse.
