Body Dysmorphic Disorder (BDD) is a psychiatric condition characterized by excessive preoccupation with perceived flaws in physical appearance, often encountered in dermatologic settings.
Objective
This study aims to validate the Arabic Body Dysmorphic Disorder Questionnaire (BDDQ), used in the dermatologic setting.
Methods
Using previous versions of BDDQ, we developed a scale that considers the dermatologic setting and conditions and translated it into Arabic. The new tool was assessed for its construct, structural, and criterion validity and reliability.
Results
The newly developed tool had an appropriate construct validity; it was unidimensional (57% variance explanation), with excellent internal consistency (Cronbach alpha = 0.889). The structural (significant inter-item and item-scale Spearman correlation coefficients) and criterion validity measures (AUC = 0.869) were also appropriate. Compared to a physician diagnosis of BDD, two cut-off values were defined for the scale: 11.5 for screening purposes (Se = 100%; Sp = 31%), and 18.5 for diagnostic purposes (Se = 83% and Sp = 83.5%).
Conclusion
This study developed and validated a quantitative scale in a dermatology setting, the Arabic BDDQ scale. Further studies are recommended to confirm the scale's efficiency for screening and diagnostic purposes.

Background
Major depressive disorder (MDD) and borderline personality disorder (BPD) are psychiatric conditions with overlapping clinical features but distinct pathologies. This study aims to explore the microvascular changes in superficial retinal capillary plexus (SRCP) in patients between MDD and BPD using Optical Coherence Tomography (OCT) and Optical coherence tomography angiography (OCTA), as well as determine their clinical diagnostic value.
Methods
The study involved 35 MDD patients, 36 BPD patients, and 36 healthy controls (HCs). OCTA and OCT were used to assess macular vessel density (MVD) and peripapillary vessel density (PVD), retinal nerve fiber layer (RNFL), and central retinal thickness (CRT). The study also evaluated the correlation of these ocular parameters with clinical symptoms.
Results
Both MDD and BPD patients showed significant reductions in MVD, RNFL and CRT compared to HCs (all p < 0.05). BPD patients exhibited more pronounced decreases in the foveal area, RNFL and CRT than MDD patients (all p < 0.05). These ocular changes were associated with BPD symptom severity (all p < 0.05). The RNFL and CRT demonstrated potential as diagnostic markers for BPD (AUROCs of 0.625 and 0.695, p < 0.05).
Conclusions
OCT and OCTA might differentiate between MDD and BPD by identifying specific ocular changes, suggesting distinct neurobiological mechanisms for each disorder. These technologies hold promise for improving diagnostic accuracy.

Objective
Estimate the psychometric properties of the interRAI Quality of Life for Mental Health and Addictions (interRAI QOL) instrument with users of Psychosocial Care Centers and participants of therapeutic groups in Primary Health Care, exploring age, gender, and service settings differences in quality of life.
Method
This quantitative study was conducted with 617 users from Psychosocial Care Centers and Primary Care services in two Brazilian states, Rio Grande do Sul and Rondônia. Data collection was carried out using the interRAI QOL. Confirmatory factor analysis and reliability assessment were performed using McDonald's Omega index. Non-parametric tests, including Mann-Whitney and Kruskal-Wallis, were conducted to compare the Quality-of-Life dimensions among participants based on age, gender, and care unit.
Results
The confirmatory factor analysis indicated a good fit for the hypothesized model (CFI = 0.97, RMSEA = 0.08). Reliability was adequate for all subscales according to McDonald's Omega, ranging from 0.71 to 0.88. Gender differences were observed in the well-being and health dimensions, while all dimensions except support showed significant differences based on age group. The care unit location also revealed significant differences across all dimensions. Participants from Psychosocial Care Center Alcohol and Drugs and from Primary Health Care show better QOL profiles than in other settings and regions.
Conclusion
The interRAI QOL demonstrated adequate psychometric properties and proved to be a valuable new instrument for assessing quality of life among individuals receiving care in the psychosocial care network.

Plasma phosphoethanolamine (PEA) has been proposed as a potential biomarker for depressive disorder. To further assess its diagnostic utility and relevance across psychiatric conditions, we conducted a larger observational study in a psychiatric primary care setting.
Methods
Between 2013 and 2020, 576 patients underwent DSM-5-based psychiatric assessments. Plasma PEA levels were measured in 295 patients with depressive disorders, 264 with other psychiatric disorders, and 17 with physical illnesses.
Results
PEA demonstrated moderate or high diagnostic accuracy for depressive disorder (AUC = 0.81, 95% CI: 0.78–0.85). Lower PEA levels were significantly associated with depression (OR = 16.30, p < 0.001).
Conclusions
These findings suggest that plasma PEA concentration may serve as a useful biomarker for depressive disorder. Further studies are warranted to explore its potential relationship with white matter pathology in psychiatric conditions.

Background
Growing research indicated that it is highly valuable and clinically beneficial to quantitatively measure and detect the potential presence of paranoid thinking. Among the various existing self-report instruments to measure paranoia, the Green et al. Paranoid Thoughts Scale (GPTS) was recommended as having the most well-defined, clearly articulated construct underlying its items, and the strongest psychometric qualities in general and clinical population samples. Yet, the psychometric performance of the GPTS remains unknown in the Arab language and culture. To address this gap, our study aimed to explore the psychometric properties of an Arabic translation of the shortest version of the scale (i.e., the GPTS-8).
Methods
A cross-sectional study was conducted. Data were collected during the period September 1st 2024 to January 31th 2025. A total of 552 Arabic-speaking general population adults from Tunisia aged 25.81 ± 4.86 years participated.
Results
Analyses provided support for a bidimensional model, with a first dimension referring to ideas of persecution and a second one corresponding to ideas of reference. The internal consistency reliability coefficients were high, with both Cronbach's alpha and McDonald's ω reported to be 0.83 for ideas of persecution and 0.83 for ideas of reference. Measurement invariance was established for both subscales, implying that the Arabic GPTS-8 measures the same underlying construct of paranoia in the same way across male and female respondents. Finally, paranoia scores correlated positively with psychotic experiences scores, indicating convergent validity, as well as with depression, anxiety and insomnia scores, supporting the concurrent validity of the scale.
Conclusion
By translating and validating GPTS-8 for the first time in Arabic, this study contributes to rendering the tool available to a broader array of clinicians and researchers who work with Arabic-speaking people. We believe the new Arabic version of the GPTS-8 will provide further encouragement to research and development in this yet-unexplored field among Arabic-speakers.

Background
Borderline Personality Disorder (BPD) is a severe and disabling condition. The Borderline Personality Disorder Checklist (BPDCL) was designed to specifically assess the subjective burden of a patient due to BPD symptoms. Various translations have been developed, but an assessment of the psychometric properties of these translations is needed. The aim was to examine the psychometric qualities of the BPDCL across different languages (i.e., Italian, Dutch, German, Spanish, English, and Greek).
Methods
Secondary data was used by reaching out to various researchers, who administered the BPDCL in previous studies. Five studies (N = 3199) conducted in Spain, Germany, Italy, the Netherlands, Australia, England, and Greece, were included in the current data set. The BPDCL was administered to BPD patients (N = 1131), Axis I disorder patients (N = 57), patients with other personality disorders (N = 225), and healthy controls (N = 1786). Item analyses and analyses assessing the known-groups and convergent validity were performed to investigate the psychometric properties of the checklist.
Results
Each version of the BPDCL, differing in language, demonstrated high-reliability coefficients (Cronbach's Alpha ranged from 0.93 to 0.96 and was 0.96 for the entire sample). The correlations between the BPDCL and other instruments, used in the studies, were weak to strong. Correlations greater than 0.55 were observed between the BPDCL and the scales BPDSI, SCL-90 and the BSI. In addition, the BPDCL seems to differentiate well between diagnostic groups. BPD patients scored the highest, followed by patients with other personality disorders, who in turn scored higher than Axis I disorder patients and healthy controls.
Conclusions
In general, the BPDCL possesses good psychometric properties and seems to be an adequate self-report instrument to measure the subjective burden of BPD patients.

Objectives
Gestational diabetes mellitus (GDM) affects a significant and growing proportion of women each year. We know little about how their needs and experiences change over the perinatal period. This study aims to explore the psychosocial and healthcare experiences of women with a GDM diagnosis from pregnancy to 12-month postnatal.
Methods
This is a qualitative, longitudinal study comprising of individual interviews with women diagnosed with GDM who live in the UK at three time points: 35-weeks’ gestation; 3-months postnatal; 12-months postnatal. Data will be analysed using template analysis. Comparisons will be made both between participants and timepoints to allow for biographical and temporal interpretations.
Results
This study will provide in-depth insights into women's lived-experiences, psychosocial needs, and interactions with healthcare services. Particular attention will be given to the transition between antenatal and postnatal periods.
Conclusion
Study findings will support the co-development of a tailored mother-infant dyad intervention grounded in women's needs and preferences across the perinatal period, aimed at improving long-term health outcomes for women and their children with a focus on diabetes prevention.

Objectives
The Cognitive Complaints Rating Scale in Bipolar Disorder (COBRA) is a brief self-report measure designed to capture Subjective Cognitive Complaints (SCC) experienced by patients with Bipolar Disorder (BD). This study aimed to translate the 16-item COBRA into Turkish (COBRA-TR) and comprehensively assess its psychometric properties.
Methods
We recruited 160 participants, consisting of 80 BD patients in remission and 80 controls. The psychometric evaluation included confirmatory factor analysis (CFA), calculation of internal consistency, and examination of divergent and convergent validity through Pearson's correlations with related scales. Statistical analyses were performed using the SPSSv29 and the Jamovi software of R Statistical Package.
Results
The COBRA-TR showed excellent internal consistency (Cronbach α = 0.898) and robust convergent validity, strongly correlating with the Cognitive Failures Questionnaire (r = 0.784; p < 0.001). It demonstrated moderate-to-high correlations with cognitive (r = 0.574; p < 0.001) and global functioning (r = 0.624; p < 0.001), as assessed by the Functioning Assessment Short Test. CFA provided strong support for a unidimensional factor structure. Furthermore, the COBRA-TR successfully differentiated patients from controls. Clinical variables minimally influenced the scale, though it showed weak correlations with subclinical depressive symptoms (r = 0.325; p = 0.003) and working memory performance (r = −0.250; p = 0.002).
Conclusion
Our findings highlight that the COBRA-TR is a highly reliable and valid tool, effectively capturing SCC among BD patients. Its brevity, ease of administration, and strong psychometric properties suggest its potential utility as a valuable instrument in both clinical practice and research settings.
目的双相情感障碍认知投诉评定量表（COBRA）是一种简短的自我报告量表，旨在记录双相情感障碍（BD）患者的主观认知投诉（SCC）。本研究旨在将16项COBRA翻译成土耳其语（COBRA- tr），并全面评估其心理测量特性。方法我们招募了160名参与者，包括80名缓解期BD患者和80名对照组。心理测量评估包括验证性因子分析（CFA），内部一致性计算，并通过Pearson与相关量表的相关检验发散效度和收敛效度。采用SPSSv29和R统计软件包中的Jamovi软件进行统计分析。结果COBRA-TR量表具有良好的内部一致性（Cronbach α = 0.898）和鲁棒的收敛效度，与认知失败问卷具有很强的相关性（r = 0.784; p < 0.001）。功能评估短测试显示，它与认知功能（r = 0.574; p < 0.001）和整体功能（r = 0.624; p < 0.001）具有中等到高度的相关性。CFA为一维因子结构提供了强有力的支持。此外，COBRA-TR成功地将患者与对照组区分开来。临床变量对量表的影响最小，但它与亚临床抑郁症状（r = 0.325; p = 0.003）和工作记忆表现（r = - 0.250; p = 0.002）呈弱相关性。结论我们的研究结果表明，COBRA-TR是一种高度可靠和有效的工具，可以有效地捕获BD患者的SCC。它的简洁，易于管理和强大的心理测量特性表明它在临床实践和研究环境中作为一种有价值的工具的潜在效用。

To revise the Brief Body Perception Questionnaire (BPQ-SF) for applicability in patients with coronary heart disease (CHD), and to examine its reliability and psychometric characteristics.
Methods
In Sample 1 (n = 371), items from the two subscales of the BPQ-SF were revised using expert consultation and item analysis, followed by exploratory factor analysis (EFA). Sample 2 (n = 350) was used for confirmatory factor analysis (CFA) and for evaluating structural validity, internal consistency, test–retest reliability, and criterion-related validity.
Results
The revised BPQ-SF consists of 30 items across two subscales: Body Awareness (15 items) and Autonomic Reactivity (15 items). The scale demonstrated good structural validity, internal consistency, and test–retest reliability. The total score was significantly and positively correlated with anxiety as measured by the Hospital Anxiety and Depression Scale-Anxiety subscale (HADS-A) (r = 0.368, p < 0.01).
Conclusion
The revised BPQ-SF shows sound reliability and validity in hospitalized patients with CHD and serves as a reliable tool for assessing interoceptive sensitivity and emotional states. It offers a valuable measurement basis for the early detection and intervention of anxiety in patients with coronary heart disease.

Background
Two of the most extensively utilized questionnaires for assessing symptoms of anxiety and depression are Beck Anxiety Inventory (BAI) and Beck Depression Inventory-second version (BDI-II).
Aim
Given the absence of normative data based on a representative Scandinavian cohort, the primary objective is to provide normative data from a representative Swedish general population sample and explore potential associations with sociodemographic variables.
Methods
Data was collected 2019 from a pre-stratified Swedish adult population sample (n = 2622).
Results
The average mean value showed: a mild level of anxiety (8.7 ± 9.5) and a minimal level of depression (3.4 ± 5.6). Higher BAI and BDI-II scores were observed in women and younger individuals. There was an association between educational attainment and BDI-II scores, where those with a bachelor's degree or higher reported a lower depression score. Results show that BAI and BDI-II deviate from normality but demonstrate excellent internal consistency (McDonald's omega 0.92 and 0.91, respectively). BAI had a poor model fit (RMSEA) 0.11), while BDI-II had a fair model fit (RMSEA 0.08).
Discussion
The present study presents normative data for BAI and BDI-II based on a representative sample from the Swedish general population. The model fit was not ideal, indicating caution, particularly for BAI.
