(No) escape from reality? Cigarette craving in virtual smoking environments

Cue-reactivity targeted smoking cessation intervention in individuals with tobacco use disorder: a scoping review

Objectives

Cue-reactivity is a critical step leading to the emergence of addictive psychology and the triggering of addictive behaviors within the framework of addiction theory and is considered a significant risk factor for addiction-related behaviors. However, the effect of cue-reactivity targeted smoking cessation intervention and the cue-reactivity paradigms used in the randomized controlled trials varies, which introduces more heterogeneity and makes a side-by-side comparison of cessation responses difficult. Therefore, the scoping review aims to integrate existing research and identify evidence gaps.

Methods

We searched databases in English (PubMed and Embase) and Chinese (CNKI and Wanfang) using terms synonymous with 'cue' and 'tobacco use disorder (TUD)' to April 2023, and via hand-searching and reference screening of included studies. Studies were included if they were randomized controlled trials taking cue-reactivity as an indicator for tobacco use disorder (TUD) defined by different kinds of criteria.

Results

Data were extracted on each study's country, population, methods, timeframes, outcomes, cue-reactivity paradigms, and so on. Of the 2,944 literature were retrieved, 201 studies met the criteria and were selected for full-text screening. Finally, 67 pieces of literature were selected for inclusion and data extraction. The results mainly revealed that non-invasive brain stimulation and exercise therapy showed a trend of greater possibility in reducing subjective craving compared to the remaining therapies, despite variations in the number of research studies conducted in each category. And cue-reactivity paradigms vary in materials and mainly fall into two main categories: behaviorally induced craving paradigm or visually induced craving paradigm.

Conclusion

The current studies are still inadequate in terms of comparability due to their heterogeneity, cue-reactivity can be conducted in the future by constructing a standard library of smoking cue materials. Causal analysis is suggested in order to adequately screen for causes of addiction persistence, and further explore the specific objective cue-reactivity-related indicators of TUD.

A Qualitative Investigation of Staff Feedback on an Online Learning Module on Smoking Cessation in a German Healthcare Company

Quitting smoking is a powerful way for patients to improve their own wellbeing and to significantly reduce the risk of health problems. Evidence shows that health professionals can effectively intervene in order to prevent and stop tobacco smoking in their patients. Online learning modules have proved to be effective in terms of transferring knowledge and skills. In an urban community hospital setting in Germany, a novel e-learning course for staff on the treatment of tobacco dependence was implemented in 2021. In this study, we analyzed free-text feedback of participants completing this online module in order to examine the feasibility and acceptance of this new format. We were able to reach a reasonable proportion of staff. Our qualitative analysis showed that most feedback was positive and described the module as well-designed and helpful. Some staff, however, expressed extremely negative views and did not see smoking cessation support as essential to their role in healthcare. We argue that in order to achieve a shift in attitude in healthcare staff, a change in German policy is required which includes the creation of smoke-free environments and the adherence to smoke-free policies on hospital sites. Furthermore, the provision of smoking cessation support in line with the WHO Framework Convention on Tobacco Control and a true understanding of the role of all healthcare professionals in promoting health of patients and staff will be essential.

Approach-Bias Retraining and Other Training Interventions as Add-On in the Treatment of AUD Patients

In the past two decades, a variety of cognitive training interventions have been developed to help people overcome their addictive behaviors. Conceptually, it is important to distinguish between programs in which reactions to addiction-relevant cues are trained (varieties of cognitive bias modification, CBM) and programs in which general abilities are trained such as working memory or mindfulness. CBM was first developed to study the hypothesized causal role in mental disorders: by directly manipulating the bias, it was investigated to what extent this influenced disorder-relevant behavior. In these proof-of-principle studies, the bias was temporarily modified in volunteers, either temporarily increased or decreased, with corresponding effects on behavior (e.g., beer consumption), in case the bias was successfully manipulated. In subsequent clinical randomized controlled trials (RCTs), training (away from the substance vs. sham training) was added to clinical treatment. These studies have demonstrated that CBM, as added to treatment, reduces relapse with a small effect of about 10% (similar effect size as for medication, with the strongest evidence for approach-bias modification). This has not been found for general ability training (e.g., working memory training), although effects on other psychological functions have been found (e.g., impulsivity). Mindfulness also has been found to help people overcome addictions, and different from CBM, also as stand-alone intervention. Research on (neuro-)cognitive mechanisms underlying approach-bias modification has pointed to a new perspective in which automatic inferences rather than associations are influenced by training, which has led to the development of a new variety of training: ABC training.

To Get High or to Get Out? Examining the Link between Addictive Behaviors and Escapism

Background: Escapism is a tendency to seek escape and distraction from reality or real-life problems. Past research regards escapism as a negative inducement that leads to adverse consequences when combined with substance use and other addictive activities. Existing knowledge on escapism's connection to addiction is mostly based on studies with restricted populations and lacks a comprehensive view.Objectives: Using an extensive data set, our aim was to investigate whether escapism has a consistent association with different types of addictive behaviors. In this study, we examined (1) the extent to which escapism is related to alcohol consumption, smoking, drug use, and gambling and (2) whether escapism moderates the relation between problem drinking and life satisfaction.Methods: We used cross-sectional survey data from a nationally representative stratified random sample of 2,285 respondents aged 16 to 80 years (mean [M] 45.18; standard deviation [SD] 18.75; 51.25% males) living in Finland. Linear and logistic regression models estimated the association of escapism and alcohol consumption, smoking, drug use, and gambling. The second part of the analysis focused on life satisfaction.Results: Escapism was associated with alcohol consumption, smoking and drug use, but not with gambling. Escapism moderated the association between life satisfaction and problematic alcohol use, indicating that problem drinking with escapist motives predicts lower life satisfaction than problematic alcohol use alone.Conclusions/Importance: Escapism bears a consistent relation to substance use and is a particularly strong predictor of alcohol consumption. Escapism can serve as an initial motive, a reinforcer, and an amplifier of addictive behaviors.

Clinical Relevance of Immersive Virtual Reality in the Assessment and Treatment of Addictive Disorders: A Systematic Review and Future Perspective

(1) Background: Virtual reality (VR) has been investigated in a variety of psychiatric disorders, including addictive disorders (ADs); (2) Objective: This systematic review evaluates the current evidence of immersive VR (using head-mounted displays) in the clinical assessment and treatment of ADs; (3) Method: PubMed and PsycINFO were queried for publications up to November 2020; (4) Results: We screened 4519 titles, 114 abstracts and 85 full-texts, and analyzed 36 articles regarding the clinical assessment (i.e., diagnostic and prognostic value; n = 19) and treatment (i.e., interventions; n = 17) of ADs. Though most VR assessment studies (n = 15/19) showed associations between VR-induced cue-reactivity and clinical parameters, only two studies specified diagnostic value. VR treatment studies based on exposure therapy showed no or negative effects. However, other VR interventions like embodied and aversive learning paradigms demonstrated positive findings. The overall study quality was rather poor; (5) Conclusion: Though VR in ADs provides ecologically valid environments to induce cue-reactivity and provide new treatment paradigms, the added clinical value in assessment and therapy remains to be elucidated before VR can be applied in clinical care. Therefore, future work should investigate VR efficacy in randomized clinical trials using well-defined clinical endpoints.

Virtual Reality-Based Treatment Approaches in the Field of Substance Use Disorders

Purpose

Substance use disorders (SUD) are burdening chronic conditions characterized by high relapse rates despite severe negative consequences. Substance-related cues that elicit craving by means of automatic physiological and behavioural responses have long been suggested to predict relapse. One major mechanism contributing to relapse behaviour are cue-induced behavioural approach tendencies towards the addictive agent. Recently, there has been an emerging interest in virtual reality (VR)-based approaches to assess and modify craving and its related responses. This review aims at elucidating (1) VR techniques applied in the field of SUD, (2) VR as an induction/assessment tool for biopsychological correlates of craving and (3) VR-based therapeutic approaches.

Findings

There is an emerging number of studies focusing on different substances of abuse incorporating VR in craving induction/assessment as well as therapy. Despite some limitations as missing of randomized controlled clinical trials with large samples and missing data on the long-term effects of VR treatment, the VR approach showed consistent results in eliciting and reducing craving across different substances.

Summary

This review suggests virtual reality as a promising tool for the assessment and treatment of craving among individuals with substance use disorders. Because of its ecological validity, VR unifies the benefits of a laboratory setting with the advantages of a realistic environment. Further studies with large samples and randomized controlled clinical trials using more homogenous VR techniques as well as assessment of objective biophysiological craving markers are required.
