To assess the interrater reliability, concurrent validity, and responsiveness of the Children's Eating and Drinking Activity Scale (CEDAS). Interrater reliability was assessed using an online questionnaire completed by speech and language therapists working in hospital and community settings. Participants (n=39) applied CEDAS to 12 vignettes. Interrater reliability was calculated using Krippendorff's alpha (α). Additionally, CEDAS was applied retrospectively to consecutive speech and language therapy referrals at a single hospital (n=85, median age 11 years 2 months, range 1 week-17 years 1 month). Responsiveness was assessed by comparing median CEDAS scores at referral, after initial speech and language therapy assessment, and at discharge. The Functional Status Scale (FSS) feeding domain was used to evaluate concurrent validity. Interrater reliability was excellent (Krippendorff's α=0.927). CEDAS was responsive to change, with expected score increases seen between referral and discharge (Z=-4.37, p < 0.001), and initial assessment and discharge (Z=-3.23, p < 0.001). Strong concurrent validity was established with the FSS (rs=-0.77 to -0.99, p < 0.003). CEDAS demonstrates excellent interrater reliability across clinical settings. It is a responsive tool with established construct validity when used in an acute hospital setting.

Accurate assessment of upper limb motor function is critical for guiding effective rehabilitation strategies in stroke survivors. The Fugl-Meyer Assessment for Upper Extremity (FMA-UE) is a widely used clinical tool, yet it is time-consuming and subject to inter-patient variability. A low-cost, computer vision-based exergame was developed to provide a remote rehabilitation alternative that also enables motor assessment. This approach represents a promising alternative for scalable and objective assessment, but requires validation. This study aims to evaluate the feasibility and preliminary validity of a computer vision-based exergame system for assessing upper limb motor function in individual post-stroke. Specifically, it investigates correlations between kinematic features derived from gameplay and FMA-UE scores. It is expected that gameplay-derived metrics, such as range of motion, jitter index, and average hand angle, will show moderate to strong correlations with the FMA-UE, supporting the exergame's potential as a remote assessment tool. This is a cross-sectional feasibility and preliminary concurrent validity pilot study with 15-30 individuals with chronic stroke. Participants will perform a markerless camera-based exergame producing pseudo-3D hand coordinates using MediaPipe-based hand tracking. Kinematic features, including range of motion, average hand angle, and jitter index, will be extracted from gameplay. Each participant will also be evaluated using the FMA-UE by a certified therapist. Correlation and regression analyses will assess the relationship between exergame metrics and clinical scores. Usability will be assessed using the System Usability Scale (SUS). We expect moderate to strong correlations between selected gameplay metrics and FMA-UE scores, particularly for range of motion, average hand angle, total traveled distance, jitter index, and score. The system is also expected to demonstrate high usability, indicating its feasibility for broader use in rehabilitation settings. If validated, the proposed exergame may serve as an accessible and scalable digital tool to support future development of objective assessment tools in stroke rehabilitation, potentially reducing clinical workload and enabling remote evaluations. A future large-scale study will evaluate test-retest reliability, longitudinal responsiveness, and home-based implementation.

Psychometric properties of a child health status questionnaire for Thai children with lupus: Nursing practice implications.

Pediatric caregiver stress specific to autism spectrum disorder (ASD) is associated with adverse outcomes, including reduced mental and physical well-being and family functioning. The Pediatric Inventory for Parents, short-form (PIP-SF), is a self-report measure of pediatric stress in caregivers of children with chronic health conditions. This study aims to fill a gap in the empirical literature by evaluating the psychometric properties of the PIP-SF within the previously excluded pediatric population of caregivers of children with ASD. Participants were a national sample of 363 female caregivers of children diagnosed with ASD. They completed the PIP-SF and measures related to general stress, anxiety, gratitude, perceptions of child vulnerability, and ASD characteristics. The PIP-Frequency and PIP-Difficulty demonstrated good to excellent internal consistency. Concurrent and convergent validity were evidenced by statistically significant positive correlations between the PIP-SF and key scales. Supporting discriminant validity, the scales evidenced nonsignificant correlations with a scale measuring gratitude. Scores on both scales did not significantly differ between caregivers of younger versus older children; caregivers of children with higher ASD characteristics. reported statistically significantly higher PIP-SF scores than those with lower characteristics. A unidimensional model for both scales met criteria for good fit. Results of the current study provide preliminary evidence supporting sufficient validity and reliability of the PIP-SF among female caregivers of children with ASD.

The Pediatric Inventory for Parents measures the frequency and difficulty of parental disease-related stress. We describe the psychometric properties and evaluation of the Norwegian version for mothers of infants with CHD. The Pediatric Inventory for Parents contains 42 items within four domains: (1) communication, (2) emotional functioning, (3) medical care, and (4) role function. Participants assessed the frequency and difficulty of disease-related stressful events over the previous seven days. Data were collected from 48 Norwegian-speaking mothers of infants with CHD one month after hospital discharge. The psychometric properties of the frequency subscale were explored using exploratory factor analysis, and the discriminant and concurrent validity of the total scale were examined. Factor analysis revealed that some items had poor loadings in our sample of mothers of infants with CHD. Cronbach's alpha in domains was between 0.69 and 0.90. The Pediatric Inventory for Parents discriminated between stress levels in CHD severity in both subscales and all domains (p-values 0.03 to 0.001). Difficulty of disease-related stress and symptoms of depression were moderately correlated (r = 0.56 to 0.63). The domains on the frequency subscale were multidimensional, and some items had lack of relevance to the population studied. Despite this, the Pediatric Inventory for Parents differentiated between stress in different CHD severity groups and correlated moderately with symptoms of depression. We recommend developing an infant version of the instrument. If the original version is used in mixed populations, lack of relevance of some items to infants should be accounted for.

Understanding individual differences in eating behavior is a central challenge in psychological research. Because broad traits show only weak-to-moderate links to eating, and most measures focus on behavioral outcomes, belief-level, domain-specific constructs connecting global traits to situation-specific behaviors have not been a primary focus of existing measurement approaches. This study introduces and empirically validates "Thoughts on Eating" (ToE) as a domain-specific belief system positioned between stable personality traits and specific eating behaviors. We conducted two sequential studies with Japanese adults. In Phase 1, we collected free-text responses from 100 participants to generate candidate items, then administered the resulting scale to a stratified sample of 552 adults to identify the dimensional structure of ToE through exploratory and confirmatory factor analyses. In Phase 2, we examined test-retest reliability and concurrent validity using the Expanded Mindful Eating Scale (EMES) and the Dutch Eating Behavior Questionnaire (DEBQ) in a follow-up sample of 434 participants. Exploratory and confirmatory analyses supported seven factors: "Enriching One's Heart," "Encouraging Social Communication," "Realizing Oneself," "Sustaining Oneself," "Respecting Food," "Indifference to Eating," and "Disliking Eating." The latter two represent fundamental evaluative orientations that are not well captured by most existing eating-related measures. The scale demonstrated adequate temporal stability and theoretically coherent associations with established measures. Associations with demographic variables and eating behaviors indicated that ToE is shaped by the intersection of individual characteristics and sociocultural contexts, supporting its characterization as an intermediate-level construct that is more stable than situational attitudes yet more context-sensitive than global traits. Our findings establish that ToE is a theoretically sound construct that reflects belief orientations that have received limited systematic attention in individual-differences research on eating. This study proposes a multi-level structure as a foundation for integrating personality, social, cultural, and clinical psychology perspectives, which is expected to advance our understanding of individual differences in eating behavior.

Telehealth could expand access to specialised concussion care; however, physiotherapists report low confidence in assessing physical symptoms remotely. This study adapted measures of vestibular, oculomotor, cervical and autonomic function for telehealth delivery, and evaluated their feasibility and comparability with in-person assessment. Using a repeated-measures design, 16 participants with concussion and 20 controls completed assessment modalities in random order (3×4 block randomisation). Feasibility was evaluated through completion rates, technical issues, adverse events and clinician feedback. Concurrent validity was examined using percentage agreement, Cohen's kappa, and sensitivity and specificity analyses. Telehealth assessment was feasible; most concussion participants and all controls completed the protocols, there were minimal technical issues, no adverse events and shorter administration times. Clinicians reported high usability and efficiency. High agreement and sensitivity were observed across vestibular, ocular convergence, autonomic and cervical range of motion measures. Nuanced assessment of ocular smooth pursuits showed lower agreement, and a potential ceiling effect on autonomic assessment was identified. This study preliminarily supports the feasibility and comparability of telehealth compared with in-person physical concussion assessments. Assessment of smooth pursuits and autonomic function require protocol refinement to enhance accuracy. Replication in larger samples is required to establish comparability.

Flexibility is a foundational motor skill in rhythmic gymnastics and is crucial for successful performance. While existing flexibility assessments, such as the frontal splits on an elevated surface, have been used in the field for years, psychometric properties have been underexamined. Preliminary reliability of the frontal splits on an elevated surface has been established only recently, while validity remains underexplored. The current study aimed to examine the construct validity (convergent and discriminant validity) and concurrent criterion validity of the frontal split on an elevated surface test in rhythmic gymnasts. Fifty-six rhythmic gymnasts aged between 13.63±2.25 years were included in the study. The flexibility of gymnasts was assessed using three tests: a frontal split on an elevated surface, both with a tape measure and a goniometer; a forward bend on a bench; and a frontal split with hand support in standing. Gymnasts (Participant Classification Framework (PCF) Tier 3-4 - highly trained/national to elite/international) were tested for correlations with related/unrelated constructs, in addition to standards, and for group differences (preferred limb, competition tiers). The preferred limb demonstrated superior frontal split performance (p &lt; 0.05), while Tier 3-4 groups showed no significant differences (p &gt; 0.05), likely reflecting ceiling effects at elite levels. The frontal split on an elevated surface test, measured with a tape measure at maximum foot height, demonstrated good construct validity (both convergent and discriminant) and concurrent criterion validity in rhythmic gymnasts, whereas the goniometer assessment of the same test failed due to unreliability in the hypersplit positions. The frontal split on an elevated surface test with a tape measure provides a practical, International Gymnastics Federation (FIG)-aligned tool.

BackgroundLoneliness during adolescence has increased worldwide in recent years and has been consistently associated with a broad range of adverse psychosocial outcomes. The availability of valid and reliable measures is essential for the early identification of loneliness and for the rigorous evaluation of intervention effectiveness. Nevertheless, multidimensional, psychometrically validated instruments for assessing loneliness in Greek adolescents remain limited.ObjectiveThe aim of the present study was to examine the psychometric properties of the Greek version of the Relational Provisions Loneliness Questionnaire (RPLQ; Hayden-Thomson, 1989), which assesses social and emotional dimensions of loneliness (i.e., integration and intimacy) within family and peer relationships.MethodsThe sample consisted of 503 students aged 13-14years, recruited from secondary schools through stratified random sampling. The factor structure was tested via Confirmatory Factor Analysis, while internal consistency, validity evidence, and measurement invariance across gender were examined.ResultsThe four-factor model demonstrated the best fit (CFI = .997, TLI = .997, RMSEA = .032, SRMR = .050) and yielded high standardized factor loadings (λ = .63-.93). Internal consistency was high across all dimensions (ω = .87-.92), and convergent, discriminant, and concurrent validity were supported. Measurement invariance across gender was supported at the configural, metric, and scalar (threshold) levels.ConclusionsThe Greek version of the RPLQ is a valid and reliable instrument for the multidimensional assessment of adolescent loneliness, supporting its use in research and prevention efforts.

Objective The ability to tolerate incomplete knowledge, or uncertainty, is a central clinical competence, yet it is an understudied topic. The few measures of therapist uncertainty tolerance that exist require clinical experience, limiting their usefulness for tracking development through training. We present the development and initial validation of the Clinician Helpful and Hindering Uncertainty Scale (CHUS), designed for use across all stages of clinical training. Method Based on comprehensive conceptual clarification, 68 items were constructed to reflect six facets denoting attitudes toward and dealing with uncertainty. Using confirmatory factor analysis (CFA), the measure’s conceptual fit and psychometric properties were examined in a combined sample of 376 English-speaking psychotherapists and students. Construct and concurrent validity were assessed through associations with self-efficacy, intolerance of uncertainty, professional self-doubt, and coping. Qualitative interviews with 15 participants explored the potential utility of CHUS in training. Results CFA supported a 30-item, six-factor structure. Factors showed good internal consistency (McDonald’s ω = .74-.91) and expected correlations with established measures. Qualitative analyses suggested that CHUS stimulated self-reflection and was viewed as helpful for professional development. Conclusion The CHUS shows promising initial psychometric properties and may represent a useful multidimensional measure of clinical uncertainty for research and training purposes.

To translate, culturally adapt, and validate the Roland-Morris Disability Questionnaire (RMDQ) for Malay-speaking individuals with low back pain (LBP) in Malaysia. A methodological study was conducted following established international guidelines for cross-cultural adaptation and psychometric validation. The process included forward-backward translation, expert review, content validation, face validation, and psychometric testing among individuals with LBP. Content and face validity indices were evaluated by rehabilitation professionals (n=8) and individuals with LBP (n=9). Psychometric testing was conducted with 102 participants to assess internal consistency, test-retest reliability (n=31), concurrent validity using the Malay Oswestry Disability Index, and known-groups validity. All items demonstrated excellent content and face validity (I-CVI, I-FVI, S-CVI/Ave, and S-FVI/Ave=1.00). The Malay RMDQ showed high internal consistency (Cronbach's α=0.932) and excellent test-retest reliability (ICC=0.996). Concurrent validity with the Malay Oswestry Disability Index was moderate (r=0.742, p<0.001). A preliminary known-groups comparison showed a statistically significant difference in the Malay RMDQ scores between participants with LBP and those without LBP (p=0.03). The Malay RMDQ demonstrated preliminary psychometric support, including evidence of reliability, validity, and cultural appropriateness, for assessing disability in individuals with LBP. Future research should explore its responsiveness and utility in broader populations.

Weight stigma internalization among postpartum women may differ from other populations owing to childbirth, breastfeeding, and postnatal physical recovery. Two instruments to assess the concept of weight stigma internalization-the Weight Self-Stigma Questionnaire (WSSQ) and the Weight Bias Internalization Scale (WBIS)-have not been validated in postpartum women. This study aims to evaluate and compare the reliability, factor structure, and concurrent validity between the WBIS and WSSQ in Chinese postpartum women. A total of 476 postpartum women (mean age 30.96 ± 4.67 years) completed the WSSQ and WBIS, as well as other relevant measures regarding perceived weight stigma, psychological outcomes, and eating behaviors. Height and weight were used to calculate the body mass index (BMI). Statistical analyses were performed using internal consistency analysis, confirmatory factor analysis, and correlation analysis. Both the WSSQ and the WBIS were found to have excellent internal consistency. In addition, both were associated with postpartum BMI, perceived weight stigma, adverse psychological outcomes, and restrained and emotional eating behaviors. Differently, the two-factor structure of the WSSQ was supported among postpartum women, but the one-factor WBIS was not. The WSSQ is a reliable and valid measurement tool for assessing weight stigma internalization in postpartum women. The structure of WBIS requires further validation and modification in future research.

Concurrent validity and reliability of a telehealth-based administration of the Craig Hospital Inventory of Environmental Factors in people with rheumatoid arthritis.

This study evaluated the psychometric properties of the Farsi version of the Saint Louis University Mental Status (SLUMS) examination, marking the first such investigation. The sample comprised 200 participants: 75 with normal cognition, 74 with mild cognitive impairment (MCI), and 51 with dementia. Concurrent validity was assessed using the MMSE and NUCOG; divergent validity employed the GDS-15. Exploratory factor analysis showed a unidimensional structure. Internal consistency (Cronbach's α = .719) and test-retest reliability (ICC = .717) were satisfactory. SLUMS correlated highly with MMSE (r = .787) and NUCOG (r = .861), but moderately with GDS-15 (r = -.376). It effectively discriminated dementia from MCI but showed limited ability to differentiate normal cognition from MCI. The Persian SLUMS is a suitable screening tool for detecting dementia, though caution is advised when distinguishing MCI from normal cognition.

ABSTRACT Background Predatory conferences (PCs) scam researchers by compromising them financially and professionally. This study presents the empirical development of the Pre-Attendance Conference Evaluator (PACE) to help academics assess a conference’s legitimacy. Materials and Method An expert group of six academics validated a preliminary list of PC traits. After identifying latent constructs through pilot testing, the list underwent four iterations based on statistical factor loadings to assess reliability, predictive validity, and concurrent validity. Later, confirmatory factor analysis included a battery of model-fit indices to assess the scale’s dimensionality. Results Content validity ratio and semi-structured interviews reduced the number of PC traits from 70 to 29. Cronbach’s alpha and the Kaiser-Meyer-Olkin test indicated 15 items suitable for factor analysis. Parallel analysis of pilot-testing data from 800 conference-level observations revealed the scale’s unidimensionality. Eventually, 11 items showed strong factor loadings and a high fit across model indices. Concurrent validity assessed by 616 conference-level observations showed high correlations (rs = 0.73–0.80) with existing tools. High predictive validity (>0.9) and test-retest reliability (ICC = 0.47–0.68) indicated moderate-to-good temporal stability. The ROC analysis yielded a cutoff score of < 14 to deem a conference predatory. Conclusion PACE demonstrated acceptable validity and reliability as a tool for diagnosing potentially predatory conferences.

Lower urinary tract symptoms (LUTS) impose a signi!cant burden on quality of life. Currently, no validated Thai version of the Lower Urinary Tract Dysfunction Research Network Symptom Index-29 (LURN SI-29) or its short form (SI-10) exists. Unlike the International Prostate Symptom Score (IPSS), LURN instruments comprehensively assess incontinence, pain, urgency, voiding, and nocturia across sexes. The study aimed to translate the LURN SI-29 and SI-10 into Thai and to evaluate their psychometric properties. A prospective, cross-sectional study was conducted involving 137 patients with LUTS at a tertiary hospital in Thailand. Translation was performed in accordance with Patient-Reported Outcome Consortium guidelines. Internal consistency (Cronbach's alpha), test-retest reliability (intraclass correlation coe"cient (ICC)), concurrent validity against the Thai IPSS, discriminant validity, and clinical agreement (Bland-Altman analysis). The Thai LURN SI-29 and SI-10 demonstrated excellent internal consistency (! = 0.94 and 0.85) and test-retest reliability (ICC = 0.84 and 0.82), which remained robust across all educational levels. Both instruments correlated strongly with the IPSS total score (" = 0.85 and 0.80; P < .001). Furthermore, median LURN-SI scores increased signi!cantly stepwise across IPSS mild, moderate, and severe grades (P < .001). Exploratory domain-level analysis suggested possible sex-related symptom patterns, with men scoring higher on voiding di"culties, while women exhibited greater incontinence and pelvic pain. The Thai LURN SI-29 and SI-10 are valid, reliable, and culturally appropriate. By capturing a broader symptom domain not included in the IPSS, they may support a more comprehensive LUTS evaluation. The SI-10 is ideal for rapid screening, while the SI-29 facilitates detailed assessment. Cite this article as: Jiraanankul V, Likitpanpisit P, Pattanasuwon T, et#al.
