Self Harm

Borderline personality disorder (BPD) is characterized by deficits in emotion regulation and affective liability. Of this domain, ruminative behaviors have been considered a core feature of emotion dysregulation difficulties. Despite this, inconsistencies have existed in the literature regarding which rumination type is most prominent in those with BPD symptoms. Moreover, no meta-analytic review has been performed to date on rumination in BPD. Taking this into consideration, a meta-analysis was performed to assess how BPD symptoms correlate with rumination, while also considering clinical moderator variables (i.e., BPD symptom domain, co-morbidities, GAF score) and demographic moderator variables (i.e., age, gender, sample type, and education level). Analysis of correlation across rumination domains for the entire sample revealed a medium overall correlation between BPD symptoms and rumination. When assessing types of rumination, the largest correlation was among pain rumination followed by anger, depressive, and anxious rumination. Among BPD symptom domain, affective instability had the strongest correlation with increased rumination, followed by unstable relationships, identity disturbance, and self-harm/ impulsivity, respectively. Demographic variables showed no significance. Clinical implications are considered and further therapeutic interventions are discussed in the context of rumination.

Children With Intellectual Disability

Inattention is one of the significant problems that inhibit learning among children with intellectual disabilities. However, several strategies and therapies have been developed to solve the problem. This study, therefore, investigates the effectiveness of music therapy in enhancing attention among children with intellectual disability. A pretest-posttest control experimental research design was adopted. The experiment was carried out for six weeks using Music Therapy Treatment Package on 24 children with intellectual disability that were randomly selected Modupe Cole Momerial Childcare and Treatment Home/School, Akoka, Yaba, Lagos. A validated Attention Observation Rating Scale (AORS) with a reliability coefficient of 0.88 was used for this study. Three hypotheses were tested in the study, and Analysis of Covariance (ANCOVA) was used for data analysis. This study revealed that music therapy is effective in enhancing attention among children with intellectual disabilities. Sex and level of severity of the disability were also tested as moderator variables, but they have no significant main or interaction effect with music therapy in enhancing attention for children with intellectual disability. The finding is that music therapy is significantly effective in enhancing attention for children with intellectual disability regardless of their sex or level of severity. It was concluded that attention deficit could be improved for children with intellectual disability. Therefore, Music therapy was recommended for use in the school with adequate teacher training.

Shame has been found to be a core feature of borderline personality disorder (BPD). To date, there is no existing systematic review or meta-analysis examining shame in individuals with BPD as compared to healthy controls (HCs). A meta-analysis of 10 studies comparing reported shame in BPD patients to HCs was carried out. Demographic and clinical moderator variables were included to see if they have a relationship with the effect size. Results showed that those with BPD had more reported shame than healthy controls. In addition, in BPD patients and HCs, higher education level was related to lower reported shame. In HCs, it was found that those who were younger reported a higher level of shame. Finally, among BPD patients, there was a relationship between levels of reported shame and elevated PTSD symptomatology. These findings emphasize the clinical relevance of shame in individuals with BPD and the need to formulate psychotherapeutic strategies that target and decrease shame.

Our research aims to elucidate the factors that influence the terminological implantation of a term by proposing a new typology of those factors with a method revealing how their mechanism causes terminological variation in French-language ICT. We accomplish this through an analysis of four Francophone communities: France, Quebec, Belgium, and Switzerland. After establishing a new typology, which encompasses the terminological, socio-terminological, psycho-terminological, and extra-terminological factors, we propose a hypothetical model of their mechanism by introducing three statistical concepts—dependent, independent, and moderator variables—to elucidate these factors’ relationships. We verify our model in two steps. First, for the analysis of terminological and socio- terminological factors, we examine the relations between each factor and terminological implantation of 256 French ICT terms. For this, we begin by coding the terms according to a criterion established for each factor. We then carry out a correlation analysis with Spearman’s rank correlation. Second, we analyse the psycho-terminological and extra-terminological factors with statistical tests on the answers to our questionnaire, which show significant differences between these four linguistic communities. Our analysis confirms a significant difference between the three European countries and Quebec in the mechanism of the terminological implantation factors and we conclude that the psycho-terminological and extra-terminological factors play a decisive role in this difference, which we identify as diatopic.

The Impact

Background: Recent anti-aging interventions have shown contradictory impacts of (poly)phenols regarding the prevention of cognitive decline and maintenance of brain function. These discrepancies have been linked to between-study differences in supplementation protocols. This subgroup analysis and meta-regression aimed to (i) examine differential effects of moderator variables related to participant characteristics and supplementation protocols and (ii) identify practical recommendations to design effective (poly)phenol supplementation protocols for future anti-aging interventions. Methods: Multiple electronic databases (Web of Science; PubMed) searched for relevant intervention published from inception to July 2019. Using the PICOS criteria, a total of 4303 records were screened. Only high-quality studies (n = 15) were included in the final analyses. Random-effects meta-analysis was used, and we calculated standard differences in means (SDM), effect size (ES), and 95% confidence intervals (CI) for two sufficiently comparable items (i.e., psychomotor function and brain-derived neurotrophic factor (BDNF)). When significant heterogeneity was computed (I2 > 50%), a subgroup and meta-regression analysis were performed to examine the moderation effects of participant characteristics and supplementation protocols. Results: The reviewed studies support the beneficial effect of (poly)phenols-rich supplementation on psychomotor functions (ES = −0.677, p = 0.001) and brain plasticity (ES = 1.168, p = 0.028). Subgroup analysis revealed higher beneficial impacts of (poly)phenols (i) in younger populations compared to older (SDM = −0.89 vs. −0.47 for psychomotor performance, and 2.41 vs. 0.07 for BDNF, respectively), (ii) following an acute compared to chronic supplementation (SDM = −1.02 vs. −0.43 for psychomotor performance), and (iii) using a phenolic compound with medium compared to low bioavailability rates (SDM = −0.76 vs. −0.68 for psychomotor performance and 3.57 vs. 0.07 for DBNF, respectively). Meta-regressions revealed greater improvement in BDNF levels with lower percentages of female participants (Q = 40.15, df = 6, p < 0.001) and a skewed scatter plot toward a greater impact using higher (poly)phenols doses. Conclusion: This review suggests that age group, gender, the used phenolic compounds, their human bioavailability rate, and the supplementation dose as the primary moderator variables relating to the beneficial effects of (poly)phenol consumption on cognitive and brain function in humans. Therefore, it seems more advantageous to start anti-aging (poly)phenol interventions in adults earlier in life using medium (≈500 mg) to high doses (≈1000 mg) of phenolic compounds, with at least medium bioavailability rate (≥9%).

The Relationship

Reduced specificity of autobiographical memory has been well established in depression, but whether this ‘overgenerality’ extends to future thinking has not been the focus of a meta-analysis. Following a preregistered protocol, we searched six electronic databases, Google Scholar, personal libraries, and contacted authors in the field for studies matching search terms related to depression, future thinking, and specificity. We reduced an initial 7,332 results to 46 included studies, with 89 effect sizes and 4,813 total participants. Random effects meta-analytic modelling revealed a small but robust correlation between reduced future specificity and higher levels of depression (r = .13, p &lt; .001). Of the 11 moderator variables examined, the most striking effects related to the emotional valence of future thinking (p &lt; .001) and the sex of participants (p = .025). Namely, depression was linked to reduced specificity for positive (but not negative or neutral) future thinking, and the relationship was stronger in samples with a higher proportion of males. This meta-analysis contributes to our understanding of how prospection is altered in depression and dysphoria and, by revealing areas where current evidence is inconclusive, highlights key avenues for future research.
