Abstract [en]

Responsible gambling (RG) tools are globally widespread; they aim to prevent or decrease the harm caused by gambling. However, existing research suggests that several included features do not decrease gambling or significantly reduce the subsequent harm. Most of the previous studies have used gambling data to understand the changes in gambling behavior. However, the literature lacks research regarding gamblers' experience and perception of RG tools, which may provide insight into increasing the usage and effectiveness of RG tools. This mixed-methods study aimed to explore gamblers' perception of their risk assessment in the RG tool Playscan regarding developing harmful gambling problems. Overall, 757 participants rated the perceived accuracy of their risk assessment and their perception of the overall RG tool that conducted the assessment. Participants were also allowed to leave a comment providing feedback, which was analyzed using thematic analysis. Quantitative data was analyzed using logistic regression and structural equation modeling. Qualitative analyses revealed that most of the participants were pleased with the risk assessment and found it helpful. Moderated mediation analysis showed that participants' assessment agreement partially mediated the association between expressing a negative view and their general view of Playscan. These results highlight the need to decrease the level of disagreement for promoting a better general view of RG tools to potentially increase their usage and effectiveness.

Abstract [en]

GamTest is a self-rating scale of negative consequences of gambling, included in the popular responsible gambling tool Playscan as part of an overall risk assessment and feedback feature. Two previous psychometric evaluations of this instrument yielded contradictory results: in an online high-gambling population, a five-factor model was supported and the instrument had overall good psychometric properties, but in a low-gambling population, the same factor structure was not supported. Because GamTest is used with both low- and high-gambling populations, more psychometric research is needed to fully understand how the instrument works. The current study examined, for the first time, psychometric performance among a sample of low-gambling respondents using a Rasch analysis. Results indicated that the instrument could be improved by decreasing the scale-steps and removing several problematic items demonstrating misfit. Furthermore, the findings indicated that some items functioned differently depending on gender, and that a shortened, improved nine-item version could not differentiate between different levels of risk. Our findings suggest that the instrument would arguably benefit from being adapted for use in a low-gambling population.

Abstract [en]

Background: Internet-based cognitive behaviour therapy (ICBT) is a promising format for treating different psychiatric disorders. In addition, several clinical trials have found positive results when using it to target transdiagnostic processes, such as perfectionism. However, few qualitative investigations have been conducted on the experiences of clients undergoing such treatments.

Method: In the current study, clients completing 12-week guided ICBT for perfectionism responded to open-ended questions at post-treatment. In total, 30 out of 62 (48.4%) described their impressions of its content and the support provided by their guide.

Results: The results were analysed qualitatively using thematic analysis. Five themes were found in the responses: Learning how to do things differently, Noticing the positives, Feeling safe to be honest, A comfortable treatment format and Barriers to treatment.

Conclusions: The results suggest that many clients were able to achieve a change in perspective in relation to their perfectionism and started facing their fears. They were also able to report the benefits of doing things differently as part of treatment, such as an improvement in their interpersonal relationships. Most clients were also positive about the treatment format, enjoying its flexibility and the encouragement offered by their therapist. However, obstacles such as conflicting commitments, personal difficulties, time-consuming and comprehensive treatment modules, and a desire for more support were brought up by some, suggesting that there are aspects that could be considered in the future.

Abstract [en]

Workplace health promotion programs (WHPPs) refer to a set of health promotion and protection strategies implemented at a worksite and designed to meet the health and safety needs of employees. One important question for WHPPs is how middle management experience their participation in a WHPP. This study aims to explore this question further by applying a qualitative content analysis to interviews with thirteen managers and ten human resource officers participating in a WHPP focusing on problem gambling. The WHPP consisted of two components: policy implementation and skills-development training. The participants were interviewed about their experiences of these two components and the implementation process. The qualitative content analysis resulted in six themes: (1) Expectations of the skills-development training, (2) Experiences of and prior beliefs about problem gambling, (3) A good foundation, (4) The difficult conversation, (5) Appreciated aspects of the training sessions, and (6) Remaining obstacles. The results suggest that the presentation of cases, facts, and general knowledge was appreciated by most participants. However, participants also expressed that they would benefit from tailored interventions, more support in the policy implementation process, and following up on the results.

Abstract [en]

Ample evidence supports the use of Virtual Reality for anxiety disorders. Throughout 20 years of research there have continuous advancements, not only in the quality of studies but also in the diversity of populations included as well as the technological progresses developed. All those steps forwards are accurately compiled in several meta-analysis, reviews and chapters. Nonetheless, there is no evidence yet on the potential negative effects and its moderators that Virtual Reality treatment strategies can provoke.

From the diversity of negative effects’ operationalizations, this study uses the deterioration rates concept defined as the worsening of the clinical symptomatology from the pre-test scores to the post-test scores using the Reliable Change Index (RCI). An individual patient data meta-analyses (IPDMA) approach that systematically reviewed all the randomized control trials in Virtual Reality and gathered 16 datasets from the total 35 studies conducted within the field of research. A total of 846 patients constitutes the sample of the study. RCI’s for each primary outcome measure is performed as well as moderator analyses for demographic variables. In this talk the results will be discussed in terms of their clinical and research implications regarding the current status and future challenges of Virtual Reality therapy in the clinical psychology realm.

Abstract [en]

Background: Perfectionism can become a debilitating condition that may negatively affect functioning in multiple areas, including mental health. Prior research has indicated that internet-based cognitive behavioral therapy can be beneficial, but few studies have included follow-up data.

Objective: The objective of this study was to explore the outcomes at follow-up of internet-based cognitive behavioral therapy with guided self-help, delivered as 2 separate randomized controlled trials conducted in Sweden and the United Kingdom.

Methods: In total, 120 participants randomly assigned to internet-based cognitive behavioral therapy were included in both intention-to-treat and completer analyses: 78 in the Swedish trial and 62 in the UK trial. The primary outcome measure was the Frost Multidimensional Perfectionism Scale, Concern over Mistakes subscale (FMPS CM). Secondary outcome measures varied between the trials and consisted of the Clinical Perfectionism Questionnaire (CPQ; both trials), the 9-item Patient Health Questionnaire (PHQ-9; Swedish trial), the 7-item Generalized Anxiety Disorder scale (GAD-7; Swedish trial), and the 21-item Depression Anxiety Stress Scale (DASS-21; UK trial). Follow-up occurred after 6 months for the UK trial and after 12 months for the Swedish trial.

Results: Analysis of covariance revealed a significant difference between pretreatment and follow-up in both studies. Intention-to-treat within-group Cohen d effect sizes were 1.21 (Swedish trial; 95% CI 0.86-1.54) and 1.24 (UK trial; 95% CI 0.85-1.62) for the FMPS CM. Furthermore, 29 (59%; Swedish trial) and 15 (43%; UK trial) of the participants met the criteria for recovery on the FMPS CM. Improvements were also significant for the CPQ, with effect sizes of 1.32 (Swedish trial; 95% CI 0.97-1.66) and 1.49 (UK trial; 95% CI 1.09-1.88); the PHQ-9, effect size 0.60 (95% CI 0.28-0.92); the GAD-7, effect size 0.67 (95% CI 0.34-0.99); and the DASS-21, effect size 0.50 (95% CI 0.13-0.85).

Conclusions: The results are promising for the use of internet-based cognitive behavioral therapy as a way of targeting perfectionism, but the findings need to be replicated and include a comparison condition.

Abstract [en]

During the last two decades, Internet-delivered cognitive behavior therapy (ICBT) has been tested in hundreds of randomized controlled trials, often with promising results. However, the control groups were often waitlist, care-as-usual or attention control. Hence, little is known about the relative efficacy of ICBT as compared to face-to-face cognitive behavior therapy (CBT). In addition, the long-term effects of ICBT is largely unknown.

In this presentation a systematic review and meta-analysis, which included 1418 participants, will be presented. Out of the 2078 articles screened, a total of 20 studies met all inclusion criteria. These included studies on social anxiety disorder, panic disorder, depression, body dissatisfaction etc. Results showed a pooled effect size at post-treatment of Hedges g = 0.05 (95% CI, -0.09 to 0.20), indicating that ICBT and face-to-face treatment produced equivalent overall effects.

We also reviewed studies in which the long-term effects of guided ICBT were investigated. Following a new set of literature searches in PubMed and other sources meta-analytic statistics were calculated for 14 studies involving a total of 902 participants, and an average follow-up period of three years. The duration of the actual treatments was usually short (8-15 weeks). The pre-to follow-up (>2 yrs) effect size was Hedge’s g = 1.52, but with a significant heterogeneity. The average symptom improvement across studies was 50%.

While the overall results indicate equivalence, there have been few studies of the individual psychiatric and somatic conditions so far, and for the majority, guided ICBT has not been compared against face-to-face treatment. Thus, more research, preferably with larger sample sizes, is needed to establish the general equivalence of the two treatment formats. While effects may be overestimated, it is likely that therapist-supported ICBT can have enduring effects.

Internet-supported and therapist-guided cognitive behaviour therapy (ICBT) is effective for a range of problems in the short run, but less is known about the long-term effects with follow-ups of two years or longer.This paper reviews studies in which the long-term effects of guided ICBT were investigated. Following literature searches in PubMed and other sources meta-analytic statistics were calculated for 14 studies involving a total of 902 participants, and an average follow-up period of three years. Studies were from Sweden (n = 11) or the Netherlands (n = 3). Long-term outcome studies were found for panic disorder, social anxiety disorder, generalized anxiety disorder, depression, mixed anxiety and depression, obsessive-compulsive disorder, pathological gambling, stress and chronic fatigue. The duration of the treatments was usually short (8–15 weeks). The pre-to follow-up effect size was Hedge’s g = 1.52, but with a significant heterogeneity. The average symptom improvement across studies was 50%. Treatment seeking in the follow-up period was not documented and few studies mentioned negative effects.While effects may be overestimated, it is likely that therapist-supported ICBT can have enduring effects. Long-term follow-up data should be collected for more conditions and new technologies like smartphone-delivered treatments.
