Metacognitive biases have been repeatedly associated with transdiagnostic psychiatric dimensions of \'anxious-depression\' and \'compulsivity and intrusive thought\', cross-sectionally. To progress our understanding of the underlying neurocognitive mechanisms, new methods are required to measure metacognition remotely, within individuals over time. We developed a gamified smartphone task designed to measure visuo-perceptual metacognitive (confidence) bias and investigated its psychometric properties across two studies (N = 3410 unpaid citizen scientists, N = 52 paid participants). We assessed convergent validity, split-half and test-retest reliability, and identified the minimum number of trials required to capture its clinical correlates. Convergent validity of metacognitive bias was moderate (r(50) = 0.64, p < 0.001) and it demonstrated excellent split-half reliability (r(50) = 0.91, p < 0.001). Anxious-depression was associated with decreased confidence (β =  - 0.23, SE = 0.02, p < 0.001), while compulsivity and intrusive thought was associated with greater confidence (β = 0.07, SE = 0.02, p < 0.001). The associations between metacognitive biases and transdiagnostic psychiatry dimensions are evident in as few as 40 trials. Metacognitive biases in decision-making are stable within and across sessions, exhibiting very high test-retest reliability for the 100-trial (ICC = 0.86, N = 110) and 40-trial (ICC = 0.86, N = 120) versions of Meta Mind. Hybrid \'self-report cognition\' tasks may be one way to bridge the recently discussed reliability gap in computational psychiatry.

OBJECTIVE: Psychological suffering in patients with Malignant Mesothelioma (MM) is different from the one experienced by patients with other cancers due to its occupational or environmental etiology and its peculiar symptomatology and prognosis (i.e., poor prognosis, reduced effectiveness of the therapies, poor quality of residual life, and advanced age at the time of diagnosis). Therefore, the Mesothelioma Psychological Distress Tool-Patients (MPDT-P) has been developed to evaluate the specific profile of psychological suffering in this population. This paper describes the item selection, factor analysis, and psychometric evaluation of the revised MPDT-P.
METHODS: The analyses of the current work aimed to confirm the factorial structure found in the first version of the MPDT-P. In the case of nonfit, it aimed to find an alternative structure and causes of nonfit in the model. The search for the fit of the factorial model was conducted using a Bayesian approach.
RESULTS: The two-factor model reported in the first version of the instrument did not fit the data. Confirmatory Bayesian analyses showed adequate fit for the three-factor solution. Based on the content of the items, we labeled the factors as dysfunctional emotions, claims for justice, and anxieties about the future.
CONCLUSIONS: Integrating the MPDT-P into clinical practice could help clinicians gain insight into the specific suffering related to MM and investigate potential differences related to different occupational and environmental exposure contexts.

El AFE de los 66 cuestionarios documentó la unidimensionalidad de la escala a partir del cumplimiento de todos los criterios utilizados para su verificación. Su confiabilidad fue excelente (Alfa de Cronbach: 0,917) y su puntaje tuvo muy alta correlación con los criterios de referencia externos (POEM: Spearman\'s Rho 0,85; p < 0,0001; DLQI Spearman\'s Rho = 0,81; p < 0,0001).
CONCLUSIONS: La versión traducida al español y adaptada transculturación del cuestionario ADCT tiene características psicométricas apropiadas, lo que contribuirá a optimizar los procesos de cuidado de pacientes de habla hispana.

The Social Interaction Anxiety Scale (SIAS) is a globally used scale for clinical diagnostic purposes for social anxiety disorder (SAD). This article investigates the psychometric properties of the SIAS, followed by its adaptation and validation in Urdu. The study consisted of two phases. The initial phase involved the translation of the scale, and the second phase was of a cross-sectional nature and consisted of evaluating factor structure and psychometric properties of the scale. For this purpose, the study enrolled a purposive sample of 573 adults aged between 18 to 45 years (mean [standard deviation (SD)] age: 23.68 [4.28] years) with a diagnosis of SAD. The sample was recruited from educational institutes, hospitals, and clinics in Lahore, Pakistan. The data was collected using a demographic form and the Urdu version of the SIAS, along with the Multidimensional Psychological Flexibility Inventory (MPFI). The analyses of the study were carried out using SPSS V27 and AMOS V24. Confirmatory factor analysis revealed a single factor structure of the Urdu version of the SIAS consisting of 16 items. The psychometric values of the scale shown were excellent, as Cronbach\'s alpha equaled 0.91, convergent validity r equaled 0.37 at p less than 0.01 with psychological inflexibility, and discriminant validity r equaled -0.47 at p less than 0.01 with psychological flexibility. The study concluded that the Urdu version of the SIAS was a valid and reliable measure for the assessment of social anxiety in the Pakistani population.

OBJECTIVE: The objective of this study was to examine the psychometric properties of the EQ-5D-Y-3 L, Patient Reported Outcomes Measurement System 25-item version profile v2.0 (PROMIS-25), and Pediatric Quality of Life Inventory™ version 4.0 Generic Core Scale (PedsQL 4.0) in Chinese pediatric patients with spinal muscular atrophy (SMA).
METHODS: The data used in this study were obtained via a web-based cross-sectional survey. Parents of pediatric patients with SMA completed the proxy-reported EQ-5D-Y-3 L, PedsQL 4.0, and PROMIS-25 measures. Information about socioeconomic and health status was also obtained. The ceiling and floor effects, factorial structure, convergent validity, and known-group validity of the three measures were assessed.
RESULTS: Three hundred and sixty-three parents of children aged from 5 to 12 completed the questionnaires. Strong floor effects were observed for the physical function components of the PROMIS-25 (41.3%) and PedsQL 4.0 (67.8%). For EQ-5D-Y-3 L, 84.6% of the respondents reported having \"a lot of\" problems with the dimensions \"walking\" and \"looking after myself.\" Minimal ceiling or floor effects were observed for the EQ-5D-Y-3 L index value. The confirmatory factor analysis supported a six-factor structure for the PROMIS-25, but did not support a four-factor structure for the PedsQL 4.0. All hypothesized correlations of the dimensions among the three measures were confirmed, with coefficients ranging from 0.28 to 0.68. Analysis of variance showed that EQ-5D-Y-3 L demonstrated better known-group validity than the other two measures in 14 out of 16 comparisons.
CONCLUSIONS: The EQ-5D-Y-3 L showed better discriminant power than the other two measures. The physical health dimensions of all three measures showed the significant floor effects. These findings provide valuable insights into the effectiveness of these measures at capturing and quantifying the impact of SMA on patients\' health-related quality of life.

The Dimensional Obsessive-Compulsive Scale (DOCS) is widely used to measure obsessive-compulsive disorder (OCD) severity across four broad symptom dimensions (i.e., contamination, responsibility for harm, unacceptable thoughts, symmetry). Despite its proven utility, there is reason to suspect that the unacceptable thoughts subscale conflates different types of unacceptable thoughts that are meaningfully distinct from one another. In the current study, we first evaluated the psychometric properties of a newly developed DOCS violent and/or aggressive thoughts subscale. We then examined the factor structure, psychometric properties, and diagnostic sensitivity of a seven-factor version of the DOCS that includes the four original DOCS subscales and three more-specific versions of the unacceptable thoughts scale (i.e., sexually intrusive thoughts, violent and/or aggressive thoughts, and scrupulous or religious thoughts). The sample included 329 residential and intensive outpatients, the majority of which had a diagnosis of OCD (75.2%). The new unacceptable thoughts subscales demonstrated convergent and discriminant validity with unique associations between the subscales and depression, suicide, and perceived threat from emotions that were not present in the broader unacceptable thoughts subscale. The seven-factor version of the DOCS demonstrated slightly lower levels of diagnostic sensitivity than the original DOCS. Thus, the four-factor version of the DOCS is recommended for screening purposes. A score of 40 or higher on the seven-factor version of the DOCS best predicted a diagnosis of OCD. Overall, the three additional unacceptable thoughts subscales appear to be distinct factors that have potential value in research and clinical settings.

BACKGROUND: Understanding patient satisfaction is key to advancing pharmacy services and improving health outcomes. There is a lack of a translated and psychometrically validated tool in the Arabic language to measure patient satisfaction with pharmacy services.
OBJECTIVE: To translate the English version of the PSPSQ 2.0 into Arabic language, culturally adapt, and verify its reliability and validity.
METHODS: A community pharmacy in Riyadh, Saudi Arabia.
METHODS: A cross-sectional study was conducted between April 2021 and June 2022 among patients with diabetes attending a community pharmacy. The International Society for Pharmacoeconomics and Outcomes Research good practice guidelines for linguistic translation and cultural adaptation were used to translate and culturally adapt the English version of PSPSQ 2.0 into Arabic. The Arabic version of PSPSQ 2.0 was subjected to factor analysis using principal component analysis with varimax rotation to evaluate its validity and Cronbach\'s alpha was used to assess the reliability of PSPSQ 2.0.
RESULTS: A total of 129 (68.2% male, and mean age 50 (SD: 11.9) years) patients with diabetes participated in the study. The analysis was undertaken for the items in each of the three domains of PSPSQ 2.0: quality of care, interprofessional relationship and overall care. Exploratory factor analysis revealed validity of 92.7%, 80.5% and 96.2%, respectively. The Arabic version of PSPSQ 2.0 had high internal consistency with Cronbach\'s alpha scores 0.99, 0.95 and 0.98 for the three measured domains, respectively. The sample adequacy was 0.924.
CONCLUSIONS: The PSPSQ 2.0 was successfully translated and culturally adapted into the Arabic language and had acceptable validity and reliability to measure patient satisfaction with services provided by pharmacists in community pharmacies.

The Level of Personality Functioning Scale-Self-Report (LPFS-SR) operationalizes Criterion A of the DSM-5 Alternative Model for Personality Disorders. The current study aimed 1) to examine the internal consistency of the Portuguese version of the LPFS-SR in a community sample and a clinical sample, 2) to compare non-clinical participants (N = 282, Mage = 48.01, SD = 10.87) with two samples of clinical participants, one composed of patients with a personality disorder diagnosis (PD sample, n = 40, Mage = 46.18, SD = 13.59) and the other of patients with other psychiatric diagnoses (OD sample, n = 148, Mage = 49.49, SD = 11.88), with respect to LPFS-SR dimensions and total score, 3) to examine the capacity of the LPFS-SR to discriminate between samples through the ROC curve analyses, and 4) to examine the factor structure of the Portuguese version of the LPFS-SR. The Portuguese version of the LPFS-SR revealed adequate internal consistency results, akin to the original data, in the community and clinical samples. The community sample differed significantly from both clinical samples in all the LPFS-SR dimensions and total score. The ROC curve analysis indicated an optimal cut-off for the total score of 272.00, corresponding to a sensitivity of 75% and a specificity of 89%, in the PD vs. community samples. The LPFS-SR total score discriminative capacity between the PD and OD samples was lower, albeit also significant (area-under-the-curve of .63; p = .027; 95% CI: .52-.74). The current study provided evidence of the LPFS-SR\'s unidimensionality in both community and clinical samples. Although this study has limitations, its findings contribute to a deeper understanding of the LPFS-SR construct, as well as to its cross-cultural validation.

BACKGROUND: A primary palliative care model for cystic fibrosis (CF) recommends using the Integrated Palliative Care Outcome Scale (IPOS) for screening. Validation of the IPOS is needed.
METHODS: This secondary analysis utilized baseline data from a multisite trial of the palliative care model, Improving Life with CF. Adults with CF completed the IPOS, the Memorial Symptom Assessment Scale-CF (MSAS-CF), the CF Questionnaire-Revised (CFQ-R), the Patient Health Questionnaire (PHQ-8), the Generalized Anxiety Disorder (GAD-7), and the Perceived Stress Scale (PSS). IPOS structure was assessed using Cronbach α coefficients and a factor analysis. Construct validity was evaluated through bivariate relationships between IPOS scores and other questionnaire scores, and linear regressions assessing the extent to which the IPOS explains variance in quality-of-life domains.
RESULTS: The sample comprised 256 adults with complete IPOS data. α coefficients were .86 for the IPOS total score, .81 for the Physical Symptoms subscale, .79 for the Emotional Symptoms subscale, and .63 for the Communication/Practical Issues subscale. A two-component factor structure best aligned with the current subscales. IPOS scores were significantly associated with other measures; associations with MSAS-CF and CFQ-R subscales differentiated the IPOS Physical and Emotional subscales. The IPOS total score provided unique information about the variance in the CFQ-R Physical Functioning and Respiratory Symptoms domain scores.
CONCLUSIONS: In adults with CF, the IPOS has acceptable internal consistency and there is evidence of construct validity. These findings support adoption of the IPOS in the primary palliative care model for CF.

Cognitive decline, particularly in dementia, presents complex challenges in early detection and diagnosis. While Item Response Theory (IRT) has been instrumental in identifying patterns of cognitive impairment through psychometric tests, its parametric models often require large sample sizes and strict assumptions. This creates a need for more adaptable, less demanding analytical methods. This study aimed to evaluate the effectiveness of Mokken scale analysis (MSA), a nonparametric IRT model, in identifying hierarchical patterns of cognitive impairment from psychometric tests. Using data from 1164 adults over 60 years old, we applied MSA to the orientation subscale of ACE-III. Our analysis involved calculating scalability, monotone homogeneity, invariant item ordering (IIO) and response functions. The MSA effectively retrieved the hierarchical order of cognitive impairment patterns. Most items showed strong scalability and consistent patterns of cognitive performance. However, challenges with IIO were observed, particularly with items having adjacent difficulty parameters. The findings highlight MSA\'s potential as a practical alternative to parametric IRT models in cognitive impairment research. Its ability to provide valuable insights into patterns of cognitive deterioration, coupled with less stringent requirements, makes it a useful tool for clinicians and researchers.
