Measuring craving: A systematic review and mapping of assessment instruments. What about sexual craving?

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.

Longitudinal Assessment of a Manualized Group Treatment Program for Gambling Disorder: The Ohio Problem Gambling Treatment Model for Adults with Co-Occurring Disorders

Individuals with gambling disorder (GD) experience a host of negative psychosocial and physical health outcomes, yet few seek treatment. Of particular concern are individuals with co-occurring mental and behavioral health disorders, a group at higher risk for GD in the state of Ohio. To better serve this population, the Ohio Department of Mental Health and Addiction Services developed a group-based GD treatment manual for adults with co-occurring disorders. Over the course of 5 years, 353 individuals engaged in at least some of the manual's 12 weekly modules, and more than one-third (n = 122) completed the entire curriculum. Participants who completed all 12 modules completed pre-and post-tests, and after controlling for covariates, participants significantly decreased their GD symptom severity, though changes in self-esteem and gambling urges were non-significant. These findings suggest the treatment manual holds promise at reducing gambling behaviors for individuals with co-occurring disorders, but further research is warranted to explore best practices on how to intervene on the psychological antecedents to gambling in this population.

Gambling in adolescence: a narrative review of the last 20 years

BACKGROUND

Gambling has increasingly become a problem in adolescence over the last 20 years. Previous research has failed to identify exactly the level of involvement of adolescents in gambling, yet a relevant presence of addictive behaviors was noticed.

OBJECTIVE

This narrative review highlights the implications of adolescent gambling, taking into consideration the main risk and protection factors aimed at limiting gambling activity, as well as the main links with the impulse-control disorder, addiction, and behavioral addiction.

METHODS

The review process was conducted through Medline, Scopus, Web of Science and Google Scholar search engines. The considered keywords were "Gambling" AND "Adolescence," "Behavioral addiction," AND "Adolescence." The articles related to gambling and adolescence in the last 20 years were included in compliance with inclusion and exclusion criteria, to perform a consistent analysis of the phenomenon and the related maintenance factors.

RESULTS

Starting from 1067 articles, 107 were selected to denote the main thematic areas involved in the gambling problem. The online search was completed on December 13, 2019.

CONCLUSIONS

The narrative review of literature can facilitate the analysis of gambling problems in adolescence, as the main studies in the last 20 years showed the complexity of the problem, the links between addiction, and the most effective methods of prevention and treatment.

Neural substrates of cue reactivity and craving in gambling disorder

Cue reactivity is an established procedure in addictions research for examining the subjective experience and neural basis of craving. This experiment sought to quantify cue-related brain responses in gambling disorder using personally tailored cues in conjunction with subjective craving, as well as a comparison with appetitive non-gambling stimuli. Participants with gambling disorder (n=19) attending treatment and 19 controls viewed personally tailored blocks of gambling-related cues, as well as neutral cues and highly appetitive (food) images during a functional magnetic resonance imaging (fMRI) scan performed ~2-3 h after a usual meal. fMRI analysis examined cue-related brain activity, cue-related changes in connectivity and associations with block-by-block craving ratings. Craving ratings in the participants with gambling disorder increased following gambling cues compared with non-gambling cues. fMRI analysis revealed group differences in left insula and anterior cingulate cortex, with the gambling disorder group showing greater reactivity to the gambling cues, but no differences to the food cues. In participants with gambling disorder, craving to gamble correlated positively with gambling cue-related activity in the bilateral insula and ventral striatum, and negatively with functional connectivity between the ventral striatum and the medial prefrontal cortex. Gambling cues, but not food cues, elicit increased brain responses in reward-related circuitry in individuals with gambling disorder (compared with controls), providing support for the incentive sensitization theory of addiction. Activity in the insula co-varied with craving intensity, and may be a target for interventions.
