The study aimed to investigate the teachers’ awareness regarding twice-exceptional students. We investigated two domains of such awareness, namely, awareness of special needs, learning difficulties, and socio-emotional problems faced by the twice-exceptional student and self-efficacy in the area of instructional strategies, legal regulations, and knowledge about how to proceed with the twice-excep- tional student. Our research has shown that teachers have a relatively high level of awareness of the specific needs of students with special educational needs, regardless of the cultural context. Teachers from Turkey, Poland and Bulgaria showed a higher awareness compared to their colleagues from the Czech Republic and Italy.

This individual participant data meta-analysis aimed to investigate the effectiveness of cognitive behavioral therapy with a trauma focus (CBT-TF) for posttraumatic stress disorder (PTSD). Furthermore, we examined the effect of moderators on PTSD symptom severity. This study included randomized controlled trials comparing CBT-TF to an inactive or active comparison group for adults with PTSD. The primary and secondary outcomes were PTSD symptom severity and remission, respectively. Moderators included sociodemographic and clinical variables. Twelve studies compared CBT-TF with inactive (n = 625) and 11 with active comparison conditions (n = 706). The one-stage individual participant data meta-analysis found that CBT-TF was more effective than inactive comparison conditions (β = -0.78; OR = 2.34) and not significantly different from active comparison conditions (β = 0.02; OR = 0.53) in reducing PTSD symptom severity and achieving PTSD remission, respectively. When comparing CBT-TF with inactive treatments, moderator analysis found that divorced participants had greater PTSD symptoms postintervention following CBT-TF than participants who were single, cohabitating, or married receiving CBT-TF, both in the completer (β = 0.93) and full-sample (β = 0.59) analyses. For the active treatment comparison, moderator analysis found that participants taking psychotropic medication had lower PTSD symptoms following CBT-TF than those not taking psychotropic medication in the completer analysis (β = -0.39). Based on our moderator analyses, further research is needed to understand the effect of psychotropic medication on the CBT-TF intervention process. Moreover, divorced participants with PTSD receiving CBT-TF might benefit from enhanced support. (PsycInfo Database Record (c) 2025 APA, all rights reserved).

BackgroundOver 6 million people have fled their homes in response to the full-scale invasion of Russian armed forces into Ukraine and are forcibly displaced since the start on 4 February 2022. Refugees, both adults and children, have a high risk of developing mental health disorders, in particular post-traumatic stress disorder, depression and anxiety disorders. Research into the mental health of Ukrainian families and their needs is urgently needed. The primary aim of this study is to increase our understanding of the consequences of potentially traumatic events for the mental health of parents and children. This may inform the development of mental health and psychosocial support interventions which can be readily implemented in the family context.Methods and analysisWe will conduct a four-wave longitudinal online survey study among Ukrainian families displaced to the Netherlands. This study is a part of the Nadiya data collection, intended to assess the mental health responses of Ukrainian refugee families to the stress of war, forced migration, family separation and adaptation to new circumstances in their hosting country. Participants are assessed at four time points, approximately 6 months apart. Data collection for T1 started in May 2023. We aim to recruit a total of n=1500 participants at T1, of which n=1000 adults (18 years and older) and n=500 children (8–11 years) and teenagers (12–17 years). To investigate symptom profiles and associated risk and protective factors among parents and children, we will use latent class growth modelling.Ethics and disseminationThe data collection procedure has been approved by the Ethical Committee of the Faculty of Social Sciences of Utrecht University. Data will be deposited, stored and shared using Utrecht University’s institutional research data repository Yoda. This research project is part of the Global Collaboration on Traumatic Stress; all authors are affiliated with this network. The findings will be published in peer-reviewed, open access journals and further disseminated through conference presentations, news updates at the project website and on the websites of the Dutch Society for Traumatic Stress Studies (www.ntvp.nl), and the European Society of Traumatic Stress Studies, as well as through media contributions.Trial registration numberThe current study was registered on 26 March 2024 on The Open Science Framework (OSF): https://doi.org/10.17605/OSF.IO/9FP7U.

Pressure-relieving footwear helps prevent foot ulcers in people with diabetes. The footwear design contributes to this effect and includes the insole top cover. We aimed to assess the offloading effect of materials commonly used as insole top cover. We measured 20 participants with diabetes and peripheral neuropathy for in-shoe peak pressures while walking in their prescribed footwear with the insole covered with eight different materials, tested in randomized order. Top covers were a 3 mm or 6 mm thick open or closed-cell foam or a 6 mm thick combination of open- and closed-cell foams. We re-assessed pressures after one month of using the top cover. Peak pressures were assessed per anatomical foot region and a region of interest (i.e., previous ulceration or high barefoot pressure). Walking comfort was assessed using a 10-point Likert scale. Mean peak pressure at the region of interest varied between 167 (SD:56) and 186 (SD:65) kPa across top covers (p < 0.001) and was significantly higher for the 3 mm thick PPT than for four of the seven 6 mm thick top covers. Across 6 mm thick top covers, only two showed a significant peak pressure difference between them. Over time, peak pressures changed non-significantly from -2.7 to +47.8 kPa across top cover conditions. Comfort ratings were 8.0 to 8.4 across top covers (p = 0.863). The 6 mm thick foams provided more pressure relief than the 3 mm thick foam during walking in high-risk people with diabetes. Between the 6 mm thick foams and over time, only small differences exist. The choice of which 6 mm thick insole top cover to use may be determined more by availability, durability, ease of use, costs, or hygienic properties than by superiority in pressure-relief capacity.

BackgroundThe reported level of lumbar paraspinal intramuscular fat (IMF) in people with low back pain (LBP) varies considerably across studies using conventional T1- and T2-weighted magnetic resonance imaging (MRI) sequences. This may be due to the different thresholding models employed to quantify IMF. In this study we investigated the accuracy and reliability of established (two-component) and novel (three-component) thresholding models to measure lumbar paraspinal IMF from T2-weighted MRI. MethodsIn this cross-sectional study, we included MRI scans from 30 people with LBP (50% female; mean (SD) age: 46.3 (15.0) years). Gaussian mixture modelling (GMM) and K-means clustering were used to quantify IMF bilaterally from the lumbar multifidus, erector spinae, and psoas major using two and three-component thresholding approaches (GMM2C; K-means2C; GMM3C; and K-means3C). Dixon fat-water MRI was used as the reference for IMF. Accuracy was measured using Bland-Altman analyses, and reliability was measured using ICC3,1. The mean absolute error between thresholding models was compared using repeated-measures ANOVA and post-hoc paired sample t-tests (α = 0.05). ResultsWe found poor reliability for K-means2C (ICC3,1 ≤ 0.38), moderate to good reliability for K-means3C (ICC3,1 ≥ 0.68), moderate reliability for GMM2C (ICC3,1 ≥ 0.63) and good reliability for GMM3C (ICC3,1 ≥ 0.77). The GMM (p < .001) and three-component models (p < .001) had smaller mean absolute errors than K-means and two-component models, respectively. None of the investigated models adequately quantified IMF for psoas major (ICC3,1 ≤ 0.01). ConclusionsThe performance of automated thresholding models is strongly dependent on the choice of algorithms, number of components, and muscle assessed. Compared to Dixon MRI, the GMM performed better than K-means and three-component performed better than two-component models for quantifying lumbar multifidus and erector spinae IMF. None of the investigated models accurately quantified IMF for psoas major. Future research is needed to investigate the performance of thresholding models in a more heterogeneous clinical dataset and across different sites and vendors.

Adolescence is a period marked by important physical and social changes, which often leads to an increase of body dissatisfaction. Recent studies have shown an association between interoception and body dissatisfaction in female adolescents. One variable that may contribute to the association between interoceptive awareness and body dissatisfaction is intolerance of uncertainty (IU). This study aims to investigate multiple facets of interoceptive awareness, IU, and their relations with body dissatisfaction in adolescent girls. In a cross-sectional study, a convenience sample of 307 adolescent girls (mean age = 17.73; SD = 1.02) was recruited in the Netherlands in 2022. Three questionnaires were completed measuring interoceptive awareness, IU, and body dissatisfaction. A moderation analyses using a multiple hierarchical regression was used to investigate associations between variables. Correlation analyses indicated that several facets of lower interoceptive awareness (Not distracting, Not worrying and Trusting) were related to higher levels of body dissatisfaction. IU only marginally moderated the relationship between several domains of interoceptive awareness (Notice, Attention regulation and Emotional awareness) and body dissatisfaction. Findings suggest that experiencing bodily signals as ambiguous and uncertain may result in more complex body image issues. Within certain domains of interoceptive awareness, IU may affect the process of appraising bodily signals. Furthermore, adolescent girls who do not feel safe in their body and who find it difficult to distract their thoughts when experiencing pain or discomfort in their body may be particularly at risk for developing more complex body image disturbances and may benefit from interventions improving both interoceptive awareness and IU. Moreover, future research should focus on interoceptive awareness and IU as potential underlying mechanisms for body image issues.

LAY SUMMARY Research has shown time and time again that war has an impact on the mental well-being of Veterans and their families. But what does that impact look like when a mission is characterized by severe violations of norms and values (in other words, moral injury)? In this study, family members of Dutch Veterans talked about the impact on their lives of a mission gone bad in the former Yugoslavia, 25 years after it happened. Although most of the families were doing well, all of the families felt left alone in taking care of their Veterans after they returned and in dealing with negative press coverage. For the well-being of all, they expressed the need for more appreciation for and acknowledgement of Veterans and their families.

Prolonged grief disorder, a condition characterized by severe, persistent and disabling grief, is newly included in ICD-11 and DSM-5-TR. Prolonged grief symptoms can be effectively treated with face-to-face or internet-delivered cognitive behavioral therapy. Traumatic losses may elicit higher prevalence of severe grief reactions. While face-to-face cognitive behavioral therapy appears efficacious in treating prolonged grief symptoms in traumatically bereaved individuals, it is not yet clear if internet-based cognitive behavioral therapy is efficacious for this population. Therefore, we investigated the efficacy of a 12-week internet-delivered cognitive behavioral therapy for people bereaved through traffic accidents in a randomized waitlist-controlled trial (registration number: NL7497, Dutch Trial Register). Forty adults bereaved though a traffic accident were randomized to internet-based cognitive behavioral therapy (n = 19) or a waitlist control condition (n = 21). Prolonged grief, posttraumatic stress and depression symptoms were assessed at baseline, post-treatment and 8-week follow-up. Dropout in the treatment condition was relatively high (42%) compared to the control condition (19%). Nevertheless, multilevel analyses showed that internet-based cognitive behavioral therapy strongly reduced prolonged grief, posttraumatic stress and depression symptoms relative to the control condition at post-treatment and follow-up. We conclude that internet-based cognitive behavioral therapy appears a promising treatment for traumatically bereaved adults.

Victims of crimes have been granted increasing procedural rights to participate in the juridical process since the mid 1990s. However, knowledge about the (anti)-therapeutic effect of participation is limited. We examined the associations between symptom levels of persistent complex bereavement disorder (PCBD), posttraumatic stress disorder (PTSD), and depression and the intention to participate in a criminal trial. Furthermore, we investigated the mediating role of state anger in these associations. People who lost loved ones after a plane disaster with flight MH17 (N = 203) completed questionnaires within three weeks before the start of the criminal trial. Mediation analyses indicated that people, who did not intend to actively participate in the trial by delivering a written or oral victim statement, were less likely to experience anger, which is, in turn, associated with attenuated psychopathology levels. State anger explains 68% of the effect of the intention to exercise the right to speak on PCBD levels. An important limitation is the cross-sectional study design, which precludes conclusions about temporal associations. More research is needed to improve preparation and support of bereaved people when they intend to exercise their victim rights during a criminal trial.
