Abstract
BACKGROUND AND OBJECTIVES Patients with obsessive-compulsive disorder (OCD) have reported higher anger and aggression than healthy individuals in previous studies using explicit measures. However, studies using implicit measures have demonstrated mixed results. The aim of the present study was to investigate implicit aggressiveness in OCD using an approach-avoidance task (AAT). METHODS Seventy-eight patients with OCD and 37 healthy controls underwent structured clinical interviews and measures of anger, OCD, and depressive symptoms as well as a computerized AAT that included aggressive, peaceful, negative, and positive stimuli. RESULTS In line with previous studies, patients with OCD reported higher scores on explicit anger. With respect to the implicit measure, repeated measures ANOVAs did not show any differences in mean reaction times for pushing compared to pulling aggressive versus peaceful and negative versus positive words. However, analyses of specific OCD symptom dimensions demonstrated significantly faster reaction times for pulling compared to pushing aggressive words for patients with high scores in the OCD symptom dimensions obsessing and hoarding. LIMITATIONS Eighty percent of patients with OCD showed psychiatric comorbidities and all were seeking treatment. CONCLUSION The present study supports previous studies reporting the absence of higher aggressiveness in patients with OCD compared to healthy controls using implicit measures. However, in contrast to previous studies, we found an implicit approach bias towards aggressive self-statements for OCD patients scoring high in the symptom dimensions obsessing and hoarding compared to healthy controls. Future studies should further elucidate putative functional relationships between different OCD symptom dimensions and implicit aggressiveness.

Abstract
Background and aim Problematic pornography use (PPU) can be a manifestation of compulsive sexual behavior disorder (CSBD). Studies investigating PPU confirm approach-avoidance tendencies in response to pornographic stimuli in this population. This study show indications of the significance of the efficacy of imaginal retraining, a variant of approach bias modification, as an intervention for PPU. Methods A total of 274 participants (86.5% male; mean age = 30.65, SD = 10.13) with self-reported PPU were randomized to imaginal retraining (instruction video) or a waitlist control group. Assessments were conducted online at baseline and after the six-week intervention period. The primary outcome was a reduction in problematic pornography use. Compulsive sexual behavior, sexual desire, depressiveness, and satisfaction with the intervention served as secondary outcomes. Results Retention was low (51.7%), but comparable between groups. The retraining was performed at least once a week (the per-protocol [PP] criterion) by 51.4% of participants. The PP analyses of 111 participants showed a significant reduction in problematic pornography use (primary outcome) in the intervention compared to the control group. The intention-to-treat analyses (ITT), however, did not corroborate this result. Despite low adherence, participants rated their satisfaction with the intervention positively. Discussion and Conclusion Imaginal retraining can function as a low-threshold self-help intervention for PPU to overcome help-seeking barriers and may reduce PPU in a subgroup of users. Low adherence limits the results of this trial. Given the need for low-threshold interventions for PPU and/or CSBD, further research should focus on increasing adherence and should evaluate retraining for clinical groups. Modifications to augment efficacy are suggested.

Abstract
BACKGROUND Up to 79 % of older adults with depression do not receive treatments commensurate with guideline recommendations. Metacognitive Training-Silver (MCT-Silver) is a low-intensity group training, which aims to reduce depressive symptoms by targeting (meta)cognitive beliefs. METHODS A randomized controlled trial comparing MCT-Silver (n = 41) to cognitive remediation (n = 39) was conducted with older adults with major depressive disorder and/or dysthymia. Clinician-rated depression (Hamilton Depression Rating Scale [HDRS, primary outcome]), self-reported depression (Beck Depression Inventory-II [BDI-II]), negative cognitive beliefs, positive metacognitive beliefs, rumination, health status, quality of life, and neurocognitive functioning were assessed at baseline, eight weeks (post) and three months (follow-up). RESULTS Both groups demonstrated moderate to large reductions in depression. No superior effects of MCT-Silver on clinician-rated depression (HDRS) were detected. MCT-Silver led to greater reductions in self-reported depression and rumination at post- and follow-up. Despite this, scores at post- and follow-up assessments were similar for both groups. MCT-Silver's effect on depressive symptoms was moderated by baseline rumination, positive metacognitive beliefs and previous treatment experience. MCT-Silver was evaluated as superior according to patient appraisals. LIMITATIONS Conclusions are limited by divergent findings on measures of depression and that the study was conducted during the COVID-19 pandemic. CONCLUSIONS Whereas no superior effect of MCT-Silver was found for the primary outcome, there was a significant effect of MCT-Silver for self-reported depression and rumination. Patients endorsing rumination and positive metacognitive beliefs as well as those without previous psychological treatment may benefit more from MCT-Silver.

Abstract
BACKGROUND Despite the existence of evidence-based therapy options for the treatment of chronic pain and comorbid depressive symptoms (e.g., CBT), many individuals remain untreated. Treatment gaps result from a lack of specialists, patient fear of stigmatization, or patient immobility. Internet-based self-help interventions could serve as an anonymous and flexible alternative treatment option. In a pilot study, chronic pain patients with comorbid depressive symptoms who used a generic Internet-based depression program showed a significant reduction in depressive symptoms (but not pain symptoms) compared to a waitlist control group. Based on these findings, we developed the low-threshold, anonymous, and cost-free Internet-based self-help intervention Lenio that is tailored to the specific needs of chronic pain patients with comorbid depressive symptoms. Lenio is accompanied by the smartphone application (app) COGITO designed to increase therapeutic success. With Lenio and COGITO addressing both chronic pain and depressive symptoms, the trial aims to increase treatment effects of online interventions for chronic pain patients by reducing both depressive symptoms and pain. METHODS The effectiveness of the Internet-based self-help intervention and accompanying smartphone app will be evaluated in a randomized controlled trial (RCT). A total of 300 participants will be randomized into an intervention group (Lenio/COGITO), an active control group (depression-focused smartphone app), or a waitlist control group. Assessments will be done at baseline, after an 8-week intervention period (post), and after 16 weeks (follow-up). The primary outcome is the post-assessment reduction in "pain impairment" (mean value of impairment in daily life, free time, and work) as assessed by the DSF (German pain questionnaire). Secondary outcomes will include the reduction in depressive symptoms as well as in the severity of pain. DISCUSSION Lenio is one of the first Internet-based interventions to reduce chronic pain and depression that will be empirically evaluated. Internet-based interventions could offer a promising alternative to conventional face-to-face psychotherapy in the treatment of chronic pain patients. The primary objective of the current study is to add essential insight into the feasibility, effectiveness, and acceptance of Internet-based interventions for people with chronic pain and depressive symptoms.

Abstract
BACKGROUND Imaginal retraining (IR) is a self-help technique that targets automatic approach tendencies toward appetitive stimuli. In a randomized controlled trial (RCT; N = 384), IR reduced craving for high-calorie foods after a six-week intervention period (small effect). The aim of the present study was to evaluate long-term effects of IR in this sample. METHODS One year after baseline, participants from the initial RCT were recontacted. A visual analogue scale measuring craving, the Food Cravings Questionnaire-Trait-reduced (FCQ-T-r), the Three-Factor Eating Questionnaire, the Beck Depression Inventory, quality of life, and subjective appraisal of the intervention were assessed online. Participants were classified as users or nonusers based on self-reported usage of IR over the previous year. RESULTS Linear-mixed models showed no significant interaction effects of time and group for any outcome (trend level effects were found for two subscales of the FCQ-T-r). Yet, higher usage of IR was associated with greater symptom reduction. Although overall subjective appraisal of the intervention was comparably good to the initial study, usage of IR and completion rate were unsatisfactory. LIMITATIONS Main limitations of the present study include the nonrandomized group allocation and the low completion rate. CONCLUSIONS This study did not find evidence for the long-term efficacy of IR in individuals with craving for high-calorie foods. Only upon high usage of IR, improvement was found. However, low completion rate and usage of the intervention may have resulted in a Type-II error. Future studies may consider low-intensity professional guidance to increase adherence and assess the long-term effects of IR in RCTs.

Abstract
Imaginal retraining (IR) is a treatment derived from approach bias modification to reduce strong craving for high-calorie food. The push component (IRpush) seems to be the most effective element according to a recent dismantling trial. Conclusions derived from prior studies are limited, however, by small sample sizes and restriction of participants to women. The present study aimed to overcome these limitations and also tested a new variant of IR (3P; decoupling with the elements pull, pause, push), which has previously been found to be more effective than the standard protocol in individuals with problematic alcohol use. The study was conducted online. A total of 1,106 participants with strong craving for high-calorie food were randomized to different brief interventions of IR or a passive control group. Before and after the interventions, participants indicated their craving for high-calorie food and appraised food pictures. The main conditions of interest were IRpush and 3P. The other two experimental conditions did not contain a motor element and served as active control conditions. IRpush proved the most effective intervention and reduced craving by approximately 18%, which was significantly larger than in the passive control group. IRpush worked especially well for those with higher initial weight, higher cravings, and more dysfunctional eating behavior. The novel 3P technique significantly reduced craving across time and was especially effective for those with high BMI and craving. The study suggests that a simple self-help component of imaginal retraining, IRpush, can decrease craving for high-calorie food to a relevant extent. Future trials should elucidate whether different forms of substance-related and behavioral addictions require adapted IR or 3P protocols to increase effectiveness.

Abstract
The aim of the present study was to examine the dimensional structure of the Gambling Attitudes and Beliefs Survey (GABS). The GABS was administered to a sample of 415 individuals with self-reported problem or pathological gambling who were taking part in two different treatment studies preregistered with the German Clinical Trials Register (DRKS00013888) and ClinicalTrials.gov (NCT03372226). Exploratory factor analyses revealed a three-factor structure. We labeled the factors sensation seeking/illusion of control, luck/gambler's fallacy, and attitude/emotions. Subsequent confirmatory factor analyses proved the three-factor model superior to the one-factor model proposed by the developers of the GABS. All dimensions were significantly correlated with symptom severity scores. Group comparisons showed significantly higher factor scores on the first factor (sensation seeking/illusion of control) for individuals reporting both skill-based and chance-based gambling compared to those reporting only chance-based gambling. The present study questions the unidimensionality of the GABS. A multidimensional assessment of gambling-related cognitive biases, beliefs, and positively valued attitudes may be useful in determining treatment outcomes and goals and in the development of novel interventions.

Abstract
INTRODUCTION Craving alcohol is a core symptom of alcohol use disorder (AUD) and an important target for treatment. A new line of treatment for AUD aims at overriding the urge to consume alcohol by changing implicit cognitions via approach bias modification (ApBM). In a prior study, we tested a variant of ApBM called imaginal retraining, which reduced craving. As addiction and body-focused repetitive behaviors (BFRBs) share important symptoms (e.g., inability to resist urges), for the present study we merged imaginal retraining with a technique aimed at BFRB, called decoupling, to augment treatment effects. We hypothesized that the new technique, which is called 3P, would lead to a greater reduction in craving relative to (active) control conditions. METHODS The study was conducted online. Data from 227 participants were considered. Participants were randomized to 1 out of 5 conditions. Craving for alcohol before and after the brief intervention was the primary outcome. RESULTS Only the 3P condition lessened craving by approximately one third at an almost medium effect size (improvement: 34.5%, p = 0.003, d = 0.458). Effects were significantly larger relative to the wait-list control and two active control conditions (p's < 0.02; greater reduction than imaginal retraining at a small but nonsignificant effect size). DISCUSSION/CONCLUSION If replicated, the combination of imaginal retraining and decoupling (3P) represents a promising, easy-to-implement self-help technique to reduce immediate craving. Long-term effects in participants with formally diagnosed AUD have not yet been investigated.

Abstract
INTRODUCTION Imaginal retraining is a self-help technique that adapts the principles of approach bias modification to the imagination. Imaginal retraining has been shown to reduce craving and addictive behaviours in 3 randomized controlled trials (RCTs) on problematic alcohol consumption, overweight, and tobacco use. To date, there have been no studies evaluating the long-term efficacy of the intervention. The aim of the present study was to generate first hypotheses on the long-term efficacy of imaginal retraining in smokers in a controlled 1-year follow-up study. MATERIALS AND METHODS We recontacted the 345 participants who had taken part in an RCT on imaginal retraining for smokers 1 year later. The survey was carried out online and assessed craving for tobacco (primary outcome), smoking behaviour, well-being, and subjective appraisal. Individuals who applied the technique at least once during the previous year were categorized as the training group, whereas participants who never performed the training were categorized as the no-training group. Data were analysed using linear mixed models (LMMs). The study was preregistered as DRKS00021044. RESULTS The completion rate was 45.5%. Less than 40% used the intervention at least once in the previous 12 months. LMM analyses showed a significant reduction in craving for tobacco for the training compared to the no-training group after 1 year. No significant group differences emerged in smoking behaviour, depressive symptoms, or quality of life. Subjective appraisal of the intervention was favorable, similar to the initial study. CONCLUSION The present study provides preliminary support for the long-term efficacy of imaginal retraining on craving for tobacco but not on smoking behaviour, highlighting the importance of multimodal treatment concepts in smoking cessation that target a variety of maintaining factors. Future studies need to investigate the long-term efficacy of the intervention in prospective RCTs that test alternative ways of conveying the technique to improve adherence.

Abstract
Imaginal retraining is a variant of approach bias modification and transfers the method into one's own mind. As the technique contains multiple elements, this pilot study aimed to dismantle which of its components is most efficient in reducing craving for high-calorie food. A total of 113 women were randomly allocated to one out of six conditions containing a short intervention to mentally manipulate a picture displaying high-calorie foods. Four of the interventions involved different combinations of elements of the imaginal retraining technique, while the remaining two conditions comprised thought suppression or merely observing a picture. Participants rated their level of craving, as well as three pictures containing healthy and unhealthy foods regarding their pleasantness before and after the interventions took place. Within-group changes were assessed with paired t-tests (in case of non-normal data Wilcoxon paired t-tests) and between-group differences with one-way ANOVAs (non-parametric Kruskal-Wallis tests). A trend level reduction in craving was found in the imaginal retraining condition with and without a movement. A post hoc analysis of both conditions joint together showed a statistically significant reduction in craving. In addition, positive picture appraisal for unhealthy foods was significantly reduced in both imaginal retraining conditions (with and without movement) with medium to large effect sizes. This study demonstrated that imaginal retraining with an arm movement can reduce craving and picture appraisal for high-calorie foods significantly in a one-time application. It is a promising technique to reduce appraisal for unhealthy high-calorie foods. Future studies should repeat the experiment in situations of high craving and allow for a personalized selection of stimuli.

Abstract
The majority of individuals with problematic and pathological gambling remain untreated, and treatment barriers are high. Internet-based interventions can help to address existing barriers, and first studies suggest their potential for this target group. Within a randomized controlled trial (N = 150) with two assessment times (baseline and post-intervention), we aimed to investigate the feasibility, acceptance, and effectiveness of a self-guided Internet-based intervention targeted at gambling problems. We expected a significant reduction in gambling symptoms (primary outcome) and depressive symptoms as well gambling-specific dysfunctional thoughts (secondary outcomes) in the intervention group (IG) compared to a wait-list control group with access to treatment-as-usual (control group, CG) after the intervention period of 8 weeks. Results of the complete cases, per protocol, intention-to-treat (ITT), and frequent user analyses showed significant improvements in both groups for primary and secondary outcomes but no significant between-group differences (ITT primary outcome, F(1,147) = .11, p = .739, ηp2 < .001). Moderation analyses indicated that individuals in the IG with higher gambling and depressive symptoms, older age, and comorbid anxiety symptoms showed significant improvement relative to the CG. The intervention was positively evaluated (e.g., 96.5% rated the program as useful). Possible reasons for the nonsignificant between-group differences are discussed. Future studies should include follow-up assessments and larger samples to address limitations of the present study.

Abstract
Imaginal retraining is a noncomputerized variant of cognitive bias modification, an intervention aimed at reducing craving in substance use disorders and behavioral addictions. We conducted a dismantling study to elucidate which of its multiple components are effective and hence essential ingredients of the training and which are ineffective (and hence perhaps dispensable) in reducing craving. We randomized 187 smokers to one out of six conditions that instructed participants to perform a brief intervention. In four of these, participants were instructed to perform isolated components of the imaginal retraining protocol, and in the two other conditions participants either suppressed or simply observed (control condition) the image of a cigarette. Before and after the intervention, participants were asked to rate their level of craving and how pleasant they found three smoking-related images. We examined within-group changes by means of paired t-tests separately across conditions (trial registration: DRKS00021044). Mental distancing from cigarettes (without a corresponding actual physical movement; non-motor retraining) led to a significant decline in craving (paired t-test), which remained significant when compared to the control condition. The effects of other components of the retraining were less consistent. The present study shows that a single therapeutic "dose" of distinct components involved in imaginal retraining can reduce craving for cigarettes. Future trials should investigate the effectiveness of components of imaginal retraining not yet tested (e.g., mood induction) and whether combinations and repetition of single components strengthen or dilute efficacy.

Abstract
Approximately 90% of problem and pathological gamblers remain untreated. This treatment gap may be diminished by the implementation of low-threshold treatment programs. As cognitive distortions play a crucial role in the development and maintenance of gambling problems, interventions targeting gambling-related biases may be particularly effective. The aim of the present study was to examine the feasibility, acceptance, and safety of a novel metacognitive training for individuals with gambling problems (Gambling-MCT). Twenty-five participants were included in an uncontrolled pilot trial with two assessment points (intervention). The intervention comprised eight training modules targeting gambling-specific cognitive distortions. At baseline and post assessment, symptom severity, as measured with the PG-YBOCS, and gambling-related cognitive distortions, as measured with the GABS, were assessed. In addition, interim assessments measuring session-specific changes were conducted. Subjective appraisal was examined after each module and also post treatment. On average, participants took part in 4.16 (SD = 2.84) training sessions. Both intent-to-treat and per protocol analyses showed significant improvements on the PG-YBOCS and the GABS (dz = 0.37–1.37). After Bonferroni correction for multiple testing, linear mixed models for the analysis of session-specific changes showed no deterioration in participants’ mental state after any of the modules. Subjective appraisal of Gambling-MCT was good. The present pilot study provides first evidence for the feasibility, acceptance, and safety of Gambling-MCT. Recruitment of participants remains challenging, emphasizing the importance of overcoming patient-related treatment barriers. Future studies need to investigate the efficacy of Gambling-MCT in randomized controlled trials.

Abstract
OBJECTIVES Smoking is a highly prevalent addictive behavior with severe and life-shortening health consequences. This is the first study to evaluate the efficacy of a newly developed imaginal variant of approach bias modification (ABM) (i.e., imaginal retraining) for the reduction of craving for tobacco and actual smoking behavior. METHODS We randomized 345 smokers to imaginal retraining (self-help manual) or a control group (either active control or wait-list control). Assessments were carried out online. The treatment interval was 6 weeks. Craving for tobacco represented the primary outcome. The study was registered as DRKS00016860. RESULTS Retention was 79.7% with no difference between groups. The intention-to-treat (ITT) analyses were significant for the primary outcome (Visual Analogue Scale on craving for tobacco) as well as subjective reduction of smoking (45.5 vs. 26.4%) in favor of imaginal retraining. In the treatment group, 47.6% performed the exercises at least once. This subgroup (per-protocol [PP] sample) showed a significant reduction in tobacco dependency as measured with the Cigarette Dependence Scale (short and long forms) and the Fagerström Test for Nicotine Dependence relative to controls. Number of daily cigarettes declined to a greater extent in imaginal retraining in the PP but not ITT analysis. A small dose-effect relationship emerged between craving and frequency of performance of the technique. CONCLUSION When used regularly, imaginal retraining may reduce craving for tobacco and actual smoking behavior in a subgroup of smokers. In view of the large subgroup that did not read the manual or did not perform the exercises, alternative ways of conveying the imaginal retraining technique should be sought (e.g., demonstration via video clips). To conclude, imaginal retraining may represent a simple low-threshold technique to reduce smoking and assist current evidence-based treatment programs targeted at abstinence. It needs to be tested whether its mechanism of action deviates from standard ABM.

Abstract
Overweight and obesity are epidemic conditions. Obesity is associated with somatic and psychological sequelae, including serious life-shortening disorders (e.g., diabetes). This study aimed to evaluate the efficacy of a newly developed imaginal variant of approach bias modification (i.e., imaginal retraining) for the reduction of craving for high-calorie food. In a randomized controlled trial, 384 women with a body mass index above 25 were allocated to a wait-list control group or to two variants of imaginal retraining (ratio: 1; 0.5; 0.5). The two intervention groups were sent a manual on imaginal retraining. One group was explicitly encouraged and instructed to use electronic reminders (RER); the standard retraining group (RS) was not encouraged to use electronic reminders. Assessments were 6 weeks apart and were carried out online. Craving for high-calorie food represented the primary outcome (based on the Visual Analog Scale, VAS). Secondary outcomes included the Food Cravings Questionnaire (FCQ-T-R). The study was registered as DRKS00017220. Women in the RER group utilized the retraining technique more often than those in the RS condition, and utilization frequency in turn was associated with improvement on craving and eating behavior scales. Both intention-to-treat and per-protocol analyses showed a favorable effect of the RER group, which achieved significance on the primary outcome, as well as on several other outcomes relative to controls at a small to medium effect size. For those participants who measured their weight before and after the assessment using a scale, weight loss in the RER group was significantly greater compared to the control group. Both retraining groups (RER: 39.4%; RS: 31.1%) reduced their subjective amount of eating relative to controls (24.2%). Approximately two-thirds of the sample (68.3%) performed the exercises at least once during the study period. The present results show that, when used regularly, imaginal retraining may reduce craving for high-calorie food in overweight and obese women. Of note, there was also evidence suggestive of weight reduction, although no diet or lifestyle change was recommended in the manual. Because a large subgroup neither read the manual nor performed the exercises, we recommend that future imaginal retraining be conveyed via short video clips.
