Meta-analysis is a statistical tool used to combine and synthesise the results of multiple independent studies on a particular topic. To this end, researchers isolate important moderators and mediators to investigate their influence on outcomes. This paper introduces a novel approach to meta-analysis, known as multidimensional meta-analysis (mi-MA), to study memory performance in those with obsessive–compulsive disorder (OCD). Unlike traditional meta-analyses, mi-MA allows researchers to extract multiple data points (e.g., using different measures) from single studies and groups of participants, facilitating the exploration of relationships between various moderators while avoiding multicollinearity issues. Therefore, in the first instance, we outline the use of the mi-MA approach to quantify the impact of complex models of memory performance in individuals with OCD. This approach provides novel insights into the complex relationship between various factors affecting memory in people with OCD. By showcasing the effectiveness of mi-MA in analysing intricate data and modelling complex phenomena, the paper establishes it as a valuable tool for researchers exploring multifaceted phenomena, both within OCD research and beyond.

Despite infectious pandemics proving particularly detrimental to those with Obsessive-Compulsive Disorder (OCD), the investigation of analogous experimental paradigms is lacking. To address this gap, we conducted two studies employing vignettes that depicted contamination-related situations commonly experienced during a pandemic (e.g., Coughing into hands and failing to use hand sanitizer). We manipulated the salience of these vignettes across three levels: high contamination, low contamination, and a neutral control condition. Our examination of state anxiety and disgust responses in all participants revealed the successful manipulation of the vignettes’ impact. Specifically, individuals with more severe OCD symptoms reported significantly higher levels of state disgust and anxiety for both high and low contamination vignettes, in contrast to the group with lower symptom severity. No significant differences were observed in the neutral vignette condition between the high- and low-scoring groups. Interestingly, for those with higher OCD symptoms, high salience contamination-focused vignettes resulted in similarly elevated state disgust and anxiety, regardless of whether the vignettes were situated in public (Study 1) or domestic (Study 2) settings. This suggests that the heightened sensitivity to contamination-related scenarios observed in individuals with OCD symptoms in the present study is not confined to a specific context. These findings support the use of contamination-focused vignettes as analogues for studying infectious pandemics and provide valuable insights into OCD models, interventions, and future research.

Objective: The development of serious games for mental wellbeing is a topic of growing interest. The increase in acceptance of games as a mainstream entertainment medium combined with the immersive qualities of games provides opportunities for meaningful support and intervention in mental wellbeing. Method: We conducted a systematic review and exploratory meta-analysis to examine if aspects of the interventions influenced outcomes as measured via overall effect sizes. We employed a multilevel meta-analytic approach to accommodate the interdependency of effect sizes (18 effect sizes from 14 studies, with 2027 participants). Results: Overall, the main effect for gaming interventions on any outcome variable was small to medium sized, d =.35 (confidence interval [.23, 47], p <.001). Results revealed that the only significant moderator was the nature of the intervention. Specifically, only interventions that included a rational emotional behavioural focus significantly predicted an improvement in depression and/or anxiety in participants. Conclusion: The findings reveal promising effects for therapeutic games for mental health, but replications are needed, alongside the addressing of methodological and procedural concerns.

We employed a multilevel meta-analytic approach to accommodate the interdependency of effect sizes (18 effect sizes from 14 studies, with 2027 participants). Results: Overall, the main effect for gaming interventions on any outcome variable was small to medium sized, d = 0.35 (CI: .23, 47, p < .001). Results revealed that the only significant moderator was the nature of the intervention. Specifically, only interventions that included a Rational Emotional Behavioural focus significantly predicted an improvement in depression and/or anxiety in participants. Conclusion: The findings reveal promising effects for therapeutic games (TGs) for mental health, but replications are needed, alongside the addressing of methodological and procedural concerns.

Despite extensive coverage of a relationship between memory performance and executive function in the obsessive-compulsive disorder (OCD) literature, the relative contributions of specific aspects of executive control have remained elusive. We, therefore, extend our previous multilevel meta-analysis (Persson et al., 2021), where demand on executive function was the most significant determinant of memory deficits in OCD, and provide a finer-grained analysis of executive control via a segregation into top-down (attentional control, maintenance and updating, planning) and bottom-up (perceptual integration, perceptual salience) contributions. Our multilevel meta-analytic approach allowed us to accommodate the interdependency of 255 effect sizes from 131 studies, totaling 4,101 OCD patients. Results revealed that maintenance and updating (top-down) and perceptual integration (bottom-up) predicted memory performance generally, and specifically in those with clinical OCD. Exploratory analyses suggested that this effect may be somewhat different among subclinical OCD groups; however, these findings should be considered with conceptual and analytical caveats in mind. We explain these results via deficient sensory (perceptual integration) and working memory (maintenance and updating) gating mechanisms and propose a model to accommodate their expression in OC symptoms. In conclusion, our meta-analysis has expanded understanding of cognitive performance in OCD and identifies the possibility of untapped cognitive targets for intervention.

Despite the widespread implementation of digital learning spaces (DLS) generally in Higher Education and for COVID-19 social distancing guidelines, a coherent and unified quantification of core aspects of the DLS on student learning has remained elusive. Therefore, this work extends the earlier work of Harkin and Nerantzi (2021), where we employed Lefebvre’s (1991) Trialectic of Space to explain physical, mental, and social aspects of the DLS. In the present paper, we now quantify Lefebvre’s original dimensions (physical, mental, social) and an Extended Lefebvrian Model (ELM; adding emotional experiences) on the depth of learning (DoL) of 188 university students at an undergraduate and postgraduate level. Results revealed that physical, mental, and social dimensions explained 42% of the variance in DoL, with emotion explaining an additional 6% which justifies its addition to our ELM (48%). Furthermore, postgraduate students experienced increased anxiety, held poorer mental representations of the DLS, and rated their DoL lower versus undergraduates. Using our findings as a guide, we highlight improvements to pedagogical practice within the DLS along physical, mental, social, and emotional dimensions to improve the experiences and learning of students in the DLS.

The National Student Survey (NSS) indicates that students are less satisfied with Assessment and Feedback versus other dimensions of the NSS in Higher Education Institutions (HEIs) across the United Kingdom (UK). HEIs generally rely on quantitative Likert responses within the NSS to assess the quality of their provision while ignoring written comments. However, we propose that analysis of written comments is essential to understand students’ lived and multidimensional experiences. Therefore, we utilised a Framework Analysis to investigate students' written responses for assessment and feedback in the 2020 NSS. We identified high (n = 4) and low-scoring (n = 4) departments as those that scored the highest and lowest on assessment and feedback at an HEI institution in the UK. These groups scored above and below the NSS national average for assessment and feedback of 72.6% (Office for Students, 2020), at 84.6% and 66%, respectively. Our analysis of 10,628 words revealed five main themes of interaction and experience, assessment clarity, assessment fairness, timing, inspiration for the present and future, and eleven sub-themes. We used the frequency of words concurrently with these themes to identify areas of good pedagogical practice. For example, high-scoring departments provided easy-to-follow lectures (Theme 1) and assessment guidance (Theme 2), students perceived feedback as fair (Theme 3), tutors were appropriately responsive to students' attempts at communication (Theme 4), and assessments had clear applicability to future employability (Theme 5). Our findings highlight the suitability of our approach for academics and HEIs to improve their understanding and provision of assessment and feedback. We provide recommendations to improve assessment and feedback at a unit, program, and HEI level.

Since the conception and exponential growth of social networking sites (SNSs), technology has advanced sufficiently to allow access to them at any moment for any reason. This has given users a “virtual space” (VS) in which to communicate and “live” within (e.g., Facebook), a space which disparate research has shown to have an impact on users’ behaviors, thoughts, and emotions. The present study aimed to examine the potential for SNSs to influence the physical, mental, and social well-being of undergraduate students. To explore this in a unified fashion, we conducted in-depth interviews with 25 participants across three qualitative studies. All interview transcripts were analyzed using a recursive deductive thematic analysis. Lefebvre’s trialectic of space was examined for its applicability to students’ experiences of VS vis-à-vis SNSs. Lefebvre’s spatial triad provides a novel and coherent framework to untangle and explain the multifaceted and often complicated nature of SNS use. Analysis found correspondence between Lefebvrian triadic space and SNSs to explain the pervasive, dominant, and sometimes pathological role that SNSs can have upon everyday functioning. Implications are that a Lefebvrian approach can inform future research as a means to untangle and explain the multifaceted and often complicated nature of SNS use.

Even though memory performance is a commonly researched aspect of obsessive-compulsive disorder (OCD), a coherent and unified explanation of the role of specific cognitive factors has remained elusive. To address this, the present meta-analysis examined the predictive validity of Harkin and Kessler’s (2011b) executive function, binding complexity, and memory load (EBL) Classification System concerning affected versus unaffected memory performance in OCD. We employed a multilevel meta-analytic approach (Viechtbauer, 2010) to accommodate the interdependent nature of the EBL model and interdependency of effect sizes (305 effect sizes from 144 studies, including 4,424 OCD patients). Results revealed that the EBL model predicted memory performance; that is, as EBL demand increases, those with OCD performed progressively worse on memory tasks. Executive function was the driving mechanism behind the EBL’s impact on OCD memory performance, as it negated binding complexity, memory load, and visual or verbal task differences. Comparisons of subtask effect sizes were also generally in accord with the cognitive parameters of the EBL taxonomy. We conclude that standardized coding of tasks along individual cognitive dimensions and multilevel meta-analyses provides a new approach to examine multidimensional models of memory and cognitive performance in OCD and other disorders.
