Eye movement desensitization and reprocessing (EMDR) in patients with a personality disorder

Background: Little is known about the effects of targeting memories of adverse (childhood) events in people with a personality disorder (PD). Objective: Determining the effectiveness of brief EMDR therapy in individuals with PD. Method: In a randomized-controlled trial, 97 outpatients with a PD as main diagnosis were allocated to either five (90 minutes) sessions of EMDR therapy (n = 51) or a waiting list (WL) control condition (n = 46) followed by 3 months of treatment as usual for their PD. Individuals with posttraumatic stress disorder (PTSD) were excluded. Measurements were performed on psychological symptoms, psychological distress, and personality dysfunctioning. Outcomes were compared at baseline, post-treatment, and at 3-month follow up. Data were analysed as intent-to-treat with linear mixed models. Results: EMDR therapy yielded significant improvements with medium to large effect sizes for the primary outcomes after treatment, i.e. psychological symptoms (EMDR: d =.42; control group: d =.07), psychological distress (EMDR: d =.69; control group: d =.29), and personality functioning (EMDR: d =.41; control group: d = −.10) within groups. At 3-month follow-up, after 3 months of TAU, improvements were maintained. Significant differences were found between both groups regarding all outcome measures in favour of the EMDR group at post-treatment (ds between −.62 and −.65), and at follow-up, after 3 months of TAU (ds between −.45 and −.53). Conclusions: The results suggest that EMDR therapy can be beneficial in the treatment of patients with PDs. More rigorous outcome

Metacognitive interpersonal therapy in group (MIT‐G) for young adults with personality disorders:A pilot randomized controlled trial

Young adults with personality disorders (PD) other than borderline are in urgent need of validated treatments to help them in managing important life transitions. Therapeutic interventions focused upon social and interpersonal difficulties may facilitate these individuals in maximizing opportunities for employment, forming stable romantic relationships, and belong to social groups. It is also important that they are offered evidence-based, first-line time-limited treatments in order to maximize effectiveness and reduce costs. We developed a 16-session programme of group-based Metacognitive Interpersonal Therapy (MIT-G) including psychoeducation on the main interpersonal motives, an experiential component enabling practice of awareness of mental states; and use of mentalistic knowledge for purposeful problem-solving. We report a feasibility, acceptability, and clinical significance randomized clinical trial. Participants meeting inclusion criteria were randomized to receive MIT-G (n = 10) or waiting list+TAU (n = 10). Dropout rate was low and session attendance high (92.19%). Participants in the MIT-G arm had symptomatic and functional improvements consistent with large effect sizes. In the MIT-G arm similarly large effects were noted for increased capacity to understand mental states and regulate social interactions using mentalistic knowledge. Results were sustained at follow-up. Our findings suggest potential for applying MIT-G in larger samples to further test its effectiveness in reducing PD-related symptoms and problematic social functioning

Effects of Mowing on Methane Uptake in a Semiarid Grassland in Northern China

Background: Mowing is a widely adopted management practice for the semiarid steppe in China and affects CH4 exchange. However, the magnitude and the underlying mechanisms for CH 4 uptake in response to mowing remain uncertain. Methodology/Principal Findings: In two consecutive growing seasons, we measured the effect of mowing on CH 4 uptake in a steppe community. Vegetation was mowed to 2 cm (M2), 5 cm (M5), 10 cm (M10), 15 cm (M15) above soil surface, respectively, and control was set as non-mowing (NM). Compared with control, CH4 uptake was substantially enhanced at almost all the mowing treatments except for M15 plots of 2009. CH4 uptake was significantly correlated with soil microbial biomass carbon, microbial biomass nitrogen, and soil moisture. Mowing affects CH 4 uptake primarily through its effect on some biotic factors, such as net primary productivity, soil microbial C\N supply and soil microbial activities, while soil temperature and moisture were less important. Conclusions/Significance: This study found that mowing affects the fluxes of CH4 in the semiarid temperate steppe of north China

Review on the validity of self-report to assess work-related diseases

Self-report is an efficient and accepted means of assessing population characteristics, risk factors, and diseases. Little is known on the validity of self-reported work-related illness as an indicator of the presence of a work-related disease. This study reviews the evidence on (1) the validity of workers' self-reported illness and (2) on the validity of workers' self-assessed work relatedness of an illness. A systematic literature search was conducted in four databases (Medline, Embase, PsycINFO and OSH-Update). Two reviewers independently performed the article selection and data extraction. The methodological quality of the studies was evaluated, levels of agreement and predictive values were rated against predefined criteria, and sources of heterogeneity were explored. In 32 studies, workers' self-reports of health conditions were compared with the "reference standard" of expert opinion. We found that agreement was mainly low to moderate. Self-assessed work relatedness of a health condition was examined in only four studies, showing low-to-moderate agreement with expert assessment. The health condition, type of questionnaire, and the case definitions for both self-report and reference standards influence the results of validation studies. Workers' self-reported illness may provide valuable information on the presence of disease, although the generalizability of the findings is limited primarily to musculoskeletal and skin disorders. For case finding in a population at risk, e.g., an active workers' health surveillance program, a sensitive symptom questionnaire with a follow-up by a medical examination may be the best choice. Evidence on the validity of self-assessed work relatedness of a health condition is scarce. Adding well-developed questions to a specific medical diagnosis exploring the relationship between symptoms and work may be a good strateg
