Psychometric Properties of the Instrument for Scoring Clinical Outcomes of Research for Epidermolysis Bullosa patient score (iscorEB-p): a patient-reported outcome measure.

BACKGROUND: In contrast to clinical diagnosis via external examination, patient-related outcome measures (PROMs) allow access to patients' internal perceptions. In the case of epidermolysis bullosa (EB) - a rare disease characterized by a wide variety of symptoms and individual disease courses - it is important to integrate the patient's perspective into diagnostic processes. The Instrument for Scoring Clinical Outcomes of Research for EB (iscorEB) is an EB-specific measurement tool, combining a clinician score (iscorEB-c) and a patient questionnaire (iscorEB-p). OBJECTIVES: The aim of this study is to establish the iscorEB-p as an independent PROM tool by exploring its psychometric properties. METHODS: Sample-based psychometric testing and evaluation were performed on data collected via a multinational online cross-sectional study. RESULTS: Data analysis was performed with n = 95 participants across all EB types. The reliability and internal consistency of the iscorEB-p was excellent (α = 0.90). Principal component analysis with a varimax rotation resulted in a two-factor solution, explaining 55.6% of the total variance, with the distinct factors 'everyday life functioning' and 'specific EB symptoms'. Convergent validity was shown by high correlations to the Satisfaction With Life Scale (r = -0.52, P < 0.001), the Quality of Life in Epidermolysis Bullosa questionnaire (r = 0.72, P < 0.001) and the Epidermolysis Bullosa Family Burden of Disease questionnaire (r = -0.73, P < 0.001). CONCLUSIONS: The iscorEB-p is a reliable and valid instrument to assess patient-reported health status of people with EB.

Epidermolysis bullosa (EB) is a rare chronic condition characterized by fragility of the skin. Even minimal friction leads to the formation of blisters and wounds. People with EB are often called 'butterfly children' because their skin is as fragile as a butterfly's wings. EB affects about 500,000 people worldwide and there is currently no cure. As EB is a chronic disease, it is associated with constantly changing periods of better and worse health. To monitor the impact of EB on patients, it is important to record a range of relevant possible symptoms using a valid questionnaire. The Instrument for Scoring Clinical Outcomes of Research for EB (iscorEB) is such a measurement tool, combining a clinician score (iscorEB-c) and a patient questionnaire (iscorEB-p). However, until now, the patient questionnaire could only be used in addition to the clinician score. In this study, we aimed to emphasize patients' perspectives and strengthen the patient questionnaire so that it can be used independently. The questionnaire can support patients to assess even minimal changes over a period of the last 4 weeks. We collected data from 95 patients with EB from all over the world. Through statistical analysis, we found that the questionnaire is a useful new standalone instrument to obtain a patient-based view of their health status. Overall, our study findings suggest that the iscorEB-p is a reliable and valid tool and could be usefully applied in clinical practice, as an addition to quality-of-service monitoring and in future research studies.

Psychometric reliability, validity, and generalizability of 3MSE scores among American Indian adults: the Strong Heart Study.

OBJECTIVE: Modified Mini-Mental State Examination (3MSE) is often used to screen for dementia, but little is known about psychometric validity in American Indians. METHODS: We recruited 818 American Indians aged 65-95 for 3MSE examinations in 2010-2013; 403 returned for a repeat examination in 2017-2019. Analyses included standard psychometrics inferences for interpretation, generalizability, and extrapolation: factor analysis; internal consistency-reliability; test-retest score stability; multiple indicator multiple cause structural equation models. RESULTS: This cohort was mean age 73, majority female, mean 12 years education, and majority bilingual. The 4-factor and 2nd-order models fit best, with subfactors for orientation and visuo-construction (OVC), language and executive functioning (LEF), psychomotor and working memory (PMWM), verbal and episodic memory (VEM). Factor structure was supported for both research and clinical interpretation, and factor loadings were moderate to high. Scores were generally consistent over mean 7 years. Younger participants performed better in overall scores, but not in individual factors. Males performed better on OVC and LEF, females better on PMWM. Those with more education performed better on LEF and worse on OVC; the converse was true for bilinguals. All differences were significant, but small. CONCLUSION: These findings support use of 3MSE for individual interpretation in clinic and research among American Indians, with moderate consistency, stability, reliability over time. Observed extrapolations across age, sex, education, and bilingual groups suggest some important contextual differences may exist.

Reliability, validity, and responsiveness of the Arabic version of HIT-6 questionnaire in patients with migraine indicated for preventive therapy: A multi-center study.

BACKGROUND: The Headache Impact Test (HIT-6) is an important patient-reported outcome measure (PROM) in migraine prevention trials. OBJECTIVES: This study aimed to (i) assess the reliability and validity of the Arabic version of HIT-6 in Arabic-speaking patients experiencing migraine, and (ii) evaluate the responsiveness of HIT-6 following migraine preventive therapy. METHODS: In this prospective study, patients with migraine (n = 145) were requested to fill out a headache diary, the Arabic version of HIT-6, and Migraine Disability Assessment Scale (MIDAS) at two time points (baseline and 3 months after initiation of prophylactic treatment). Some respondents (n = 73) were requested to fill out HIT-6 again 1 week from the baseline for test-retest reliability. The intensity of migraine headache attacks was evaluated using the Visual Analogue Scale (VAS). An anchor-based method was used to establish the minimal important change (MIC) value and responsiveness of HIT-6. RESULTS: The total scores of HIT-6 were significantly correlated to a fair degree with MIDAS (r = 0.41), as well as VAS (r = 0.53), and monthly migraine days (r = 0.38) at the baseline while at the follow-up (after 3 months), the correlations were of moderate degree with MIDAS scores (r = 0.62) and monthly migraine days (r = 0.60; convergent validity). Reliability estimates of the Arabic HIT-6 were excellent (Cronbach's α = 0.91 at baseline and 0.89 at follow-up). The average measure interclass correlation coefficient (ICC) value for the test-retest reliability was 0.96 (95% confidence interval = 0.94-0.98, p < 0.001). The HIT-6 total score is sensitive to change, being significantly reduced after prophylactic treatment compared to before (effect size = 1.5, standardized response mean = 1.3). A reduction from baseline of 4.5 on HIT-6 showed the highest responsiveness to predict improvement with an area under the curve equal to 0.66, sensitivity of 80%, specificity of 45%, and significance at 0.021. Changes in the HIT-6 total score were positively correlated with changes in monthly migraine days (r = 0.40) and VAS scores (r = 0.69) but not with changes in the score of MIDAS (r = 0.07). CONCLUSION: The Arabic version of HIT-6 is valid, reliable, and sensitive to detect clinical changes following migraine prophylactic treatment with a MIC of 4.5 points.

Reliability and Validity of the Turkish Translation of the PedsQL™ 3.0 Neuromuscular Module for 2-to 4-Year-Olds in Spinal Muscular Atrophy.

BACKGROUND: The Pediatric Quality of Life Inventory™ (PedsQL™) Neuromuscular Module (PedsQL™ 3.0 NM) evaluates the health-related quality of life in children who are affected by neuromuscular diseases. This study's aim is to assess the adaptation of the PedsQL™ 3.0 NM Turkish version (PedsQL™ 3.0 NM-TR) for 2- to 4-year-olds in spinal muscular atrophy (SMA). METHODS: The procedure of translating the PedsQL™ 3.0 NM into Turkish was conducted in accordance with the translation methodology outlined by the PedsQL™ measurement model. The PedsQL™ 3.0 NM-TR was administered to 54 parents of children with SMA aged 2 to 4 years. The test-retest reliability and intraclass correlation coefficient (ICC) were measured for reliability analysis. Cronbach's α coefficient and item score correlations were calculated for internal consistency. Concurrent construct validity was evaluated by Pearson correlations between the outcomes of the PedsQL™ 4.0 Generic Core Scale (PedsQL™ 4.0 GCS) and the PedsQL™ 3.0 NM. RESULTS: The PedsQL™ 3.0 NM-TR total score shows excellent reliability. The Cronbach's α values for the PedsQL™ 3.0 NM ranged between 0.871 and 0.906, while those for the PedsQL™ 4.0 GCS ranged between 0.843 and 0.897. Test-retest ICC values for the PedsQL™ 3.0 NM-TR ranged between 0.812 and 0.917, and for the PedsQL™ 4.0 GCS ranged between 0.773 and 0.899. The relationship between the PedsQL™ 3.0 NM-TR and the subscores of the PedsQL™ 4.0 GCS demonstrated a range of correlations from excellent to fair, indicating the interplay between two scales. CONCLUSION: This study established the PedsQL™ 3.0 NM-TR as reliable, valid, and feasible for use in children aged 2 to 4 years with SMA.

Psychometric properties and normative data of the Italian version of the Cognitive Function at Work Questionnaire: a screening tool for detecting subjective cognitive complaints at work.

INTRODUCTION: Considering the extension of working life due to socioeconomic and political factors, many people may experience cognitive complaints (CC) at their workplace, with severe consequences on their quality of life. The identification of workers reporting significative SCC is crucial to eventually address them to an objective neuropsychological evaluation and implement cognitive interventions to guarantee workers' well-being. Since no Italian questionnaires for detecting CC were designed for occupational settings, the aim of the study was to validate the Italian version of the Cognitive Function at Work Questionnaire (CFWQ) and to provide its normative data. MATERIALS AND METHODS: Internal consistency, convergent and divergent validity, and factorial structure of the CFWQ were evaluated. A regression-based procedure served to compute percentiles of CFWQ and its subscales. RESULTS: Four hundred twenty-one participants without psychiatric and/or neurological disorders completed the survey. We found that the Italian CFWQ included 26 items, with a good internal consistency (Cronbach's alpha = 0.897) and a six-factor structure (memory, language, processing speed, abstract thinking/behavioral control, behavioral inertia, planning ability). CFWQ score did not correlate with empathy but correlated strongly with memory scores and moderately with anxiety and depression scores. CONCLUSIONS: The Italian CFWQ showed good psychometric properties, in analogy with the original English scale. Therefore, it can be successfully employed in organizational contexts to possibly identify workers with CC and therefore with possible co-occurrent psychological, behavioral, and cognitive consequences.

The Epilepsy Surgery Satisfaction Questionnaire (ESSQ-19): Italian language translation and validation.

OBJECTIVE: Epilepsy surgery can be proposed as a treatment option in people with focal epilepsy, however satisfaction with epilepsy surgery in Italy remains unknown. We aimed to validate in Italy an instrument to measure patient satisfaction with epilepsy surgery, the 19-item Epilepsy Surgery Satisfaction Questionnaire (ESSQ-19). METHODS: Consecutive patients with epilepsy who received epilepsy surgery between the years 2018-2021 at Modena Academic Hospital were recruited and provided clinical and demographic data. The Italian version of the ESSQ-19 and other three questionnaires were completed to assess construct validity. To evaluate the validity and reliability of the tool Spearman's rank correlation, and internal consistency analysis were performed. RESULTS: 66 out of 79 eligible patients participated in the study (22 females; median age 37 years). The mean values of satisfaction for each domain of the IT-ESSQ-19 were: seizure control 83.4; (SD 16.7), psychosocial functioning 79.3 (SD 17.1), surgical complications 90.8 (SD 14.9), and recovery from surgery 81.4 (SD 16.9). The mean summary score was 83.7 (SD 13.3). The questionnaire was shown to have high internal consistency in the four domains (Cronbach's alpha = 0.82-0.93), and no significant floor/ceiling effects of the summary score. The ESSQ-19 scores significantly correlated with other instruments to support construct validity. It also demonstrated good discriminant validity for being seizure free [AUC 0.72; 95% CI = 0.56-0.88], and to endorse depression [AUC 0.76, 95% CI = 0.56-0.96]. SIGNIFICANCE: The Italian version of the ESSQ-19 is a reliable and valid self-reported questionnaire for assessing patient satisfaction with epilepsy surgery.

Validation of the Italian version of the Questionnaire for Impulsive-Compulsive Disorders in Parkinson's Disease-Rating Scale (QUIP-RS) in an Italian Parkinson's disease cohort.

INTRODUCTION: Impulse control disorders (ICDs) frequently occur in Parkinson's disease (PD), and an early identification is essential to prevent severe psychosocial consequences. The Questionnaire for Impulsive-Compulsive Disorders in Parkinson's Disease-Rating Scale (QUIP-RS) has been developed to evaluate the severity of ICDs along with a range of impulsive-compulsive behaviors (ICBs) in PD; however, its Italian version has not yet been validated. METHODS: One hundred consecutive outpatients with PD were administered an Italian version of the QUIP-RS and a brief neuropsychological assessment to evaluate global cognitive status and scales to measure depression, apathy and impulsive disorders. We evaluated the internal consistency, convergent and divergent validity, and factorial structure of QUIP-RS. We also explored the possible association between QUIP-RS scores and clinical factors and dopaminergic medication. RESULTS: Subsyndromal ICDs manifestations were observed in 54% of the patients, and one in four (22%) reported two or more ICDs or related behaviors. The QUIP-RS demonstrated good internal consistency (Cronbach's alpha = 0.806) and construct validity, and its factorial structure reflected different ICDs and ICBs domains. No association emerged between QUIP-RS scores and the clinical aspects of PD and dopaminergic medication. CONCLUSION: We provided, for the first time, an Italian translation of the QUIP-RS and demonstrated its feasibility in clinical and research settings. Severity of ICDs was independent of clinical factors and dopaminergic medication, underlining the need to adopt a broader perspective on their etiopathology in PD.

Évaluation de la structure factorielle et des qualités psychométriques de l'Échelle de Fatigue Pandémique parmi la population adulte québécoise: Evaluation of the factorial structure and psychometric qualities of the Pandemic Fatigue Scale among Quebec adult population.

OBJECTIVE: The objective of the study is to evaluate the factorial structure and the psychometric qualities of the Pandemic Fatigue Scale among the Quebec adult population. METHOD: The data analyzed come from a web survey conducted in October 2021 among 10 368 adults residing in Quebec. The scale's factor structure and invariance by gender, age and language used to complete the questionnaire were tested using confirmatory factor analyses. Convergent and divergent validity were also assessed. Finally, the reliability of the scale was estimated from the alpha and omega coefficients. RESULTS: The analyzes suggest the presence of a bidimensional structure in the sample of Quebec adults with informational fatigue and behavioral fatigue. The invariance of the measure is noted for sex, for age subgroups and for the language used for the questionnaire. The results of convergent and divergent validity provide additional evidence for the validity of the scale. Finally, the reliability of the scale scores is excellent. CONCLUSION: The results support the presence of a bidimensional structure as in the initial work of Lilleholt et al. They also confirm that the scale has good psychometric qualities and that it can be used among the adult population of Quebec.

Psychometric properties of the Chinese version of the Hypertension Belief Assessment Tool.

BACKGROUND: Hypertension is prevalent in China. Hypertensive patients suffer from many health problems in life. Hypertension is a common chronic disease with long-term and lifelong characteristics. In the long run, the existence of chronic diseases will affect the patient's own health beliefs. However, people's health beliefs about Hypertension are not explicit. Therefore, it is vital to find a suitable instrument to comprehend and improve the health beliefs of hypertensive patients, thus, better control of blood pressure and improvement of patient's quality of life are now crucial issues. This study aimed to translate the Hypertension Belief Assessment Tool (HBAT) into Chinese and examine the psychometric properties of the Chinese version of the Hypertension Belief Assessment Tool in hypertensive patients. METHODS: This is a cross-sectional study. We translated the HBAT into Chinese and tested the reliability and validity of the Chinese version among 325 hypertensive patients. RESULTS: The Chinese version of the scale contains 21 items. The Exploratory Factor Analysis (EFA) revealed six factors and explained 77.898% of the total variation. A six-factor model eventually showed acceptable fit indices in the Confirmatory Factor Analysis (CFA). With modified Confirmatory Factor Analysis, the fit indices were Chi-square/Degree of Freedom (CMIN/DF) = 2.491, Comparative Fit Index (CFI) = 0.952, Incremental Fit Index (IFI) = 0.952, Root-mean-square Error of Approximation (RMSEA) = 0.068, Tucker Lewis Index (TLI) = 0.941. The HBAT exhibits high internal consistency reliability (0.803), and the scale has good discriminant validity. CONCLUSION: The results suggest that the HBAT is a reliable and valid instrument for assessing the beliefs of Chinese hypertensive patients.

Assessing intrinsic capacity in Taiwan: Initial psychometric properties of the Integrated Care for Older People Screening Tool for Taiwanese (ICOPES-TW).

BACKGROUND: The World Health Organization (WHO) proposed the concept of intrinsic capacity (comprising composite physical and mental capacity) which aligns with their concepts of healthy aging and functional ability. Consequently, the WHO promotes the Integrated Care for Older People (ICOPE) framework as guidance for geriatric care. Consequently, each government should have a screening tool corresponding to ICOPE framework to promote geriatric care. The present study examined the initial psychometric properties of the Taiwan version of ICOPE (i.e., ICOPES-TW). METHODS: Older people (n = 1235; mean age = 72.63 years; 634 females [51.3%]) were approached by well-trained interviewers for participation. A number of measures were administered including the ICOPES-TW, WHOQOL-AGE (assessing quality of life [QoL]), Clinical Frailty Scale (assessing frailty), Barthel Index (assessing basic activity of daily living [BADL]), and Lawton Instrumental Activities of Daily Living Scale (assessing instrumental activity of daily living [IADL]). RESULTS: The ICOPES-TW had a two-factor structure (body functionality [eigenvalue = 1.932] and life adaptation [eigenvalue = 1.170]) as indicated by the results of exploratory factor analysis. Internal consistency of the ICOPES-TW was low (Cronbach's α = 0.55 [entire ICOPES-TW], 0.45 (body functionality factor), and 0.52 (life adaptation factor). ICOPES-TW scores were significantly (i) positively correlated with age (r = 0.321), IADL (r = 0.313), and frailty (r = 0.601), and (ii) negatively correlated with QoL (r=-0.447), and BADL (r=-0.447), with all p-values < 0.001. CONCLUSION: The ICOPES-TW could be a useful screening tool for healthcare providers to quickly evaluate intrinsic capacity for Taiwanese older people given that it has moderate to strong associations with age, BADL, IADL, QoL, and frailty.

Development and validation of the osteoporosis scale among the system of quality of life instruments for chronic diseases QLICD-OS (V2.0).

BACKGROUND: Quality of life of osteoporosis patients had caused widespread concern, due to high incidence and difficulty to cure. Scale specifics for osteoporosis and suitable for Chinese cultural background lacked. This study aimed to develop an osteoporosis scale in Quality of Life Instruments for Chronic Diseases system, namely QLICD-OS (V2.0). METHODS: Procedural decision-making approach of nominal group, focus group and modular approach were adopted. Our scale was developed based on experience of establishing scales at home and abroad. In this study, Quality of life measurements were performed on 127 osteoporosis patients before and after treatment to evaluate the psychometric properties. Validity was evaluated by qualitative analysis, item-domain correlation analysis, multi-scaling analysis and factor analysis; the SF-36 scale was used as criterion to carry out correlation analysis for criterion-related validity. The reliability was evaluated by the internal consistency coefficients Cronbach's α, test-retest reliability Pearson correlation r. Paired t-tests were performed on data of ​​the scale before and after treatment, with Standardized Response Mean (SRM) being calculated to evaluate the responsiveness. RESULTS: The QLICD-OS, composed of a general module (28 items) and an osteoporosis-specific module (14 items), had good content validity. Correlation analysis and factor analysis confirmed the construct, with the item having a strong correlation (most > 0.40) with its own domains/principle components, and a weak correlation (< 0.40) with other domains/principle components. Correlation coefficient between the similar domains of QLICD-OS and SF-36 showed reasonable criterion-related validity, with all coefficients r being greater than 0.40 exception of physical function of SF-36 and physical domain of QLICD-OS (0.24). Internal consistency reliability of QLICD-OS in all domains was greater than 0.7 except the specific module. The test-retest reliability coefficients (Pearson r) in all domains and overall score are higher than 0.80. Score changes after treatment were statistically significant, with SRM ranging from 0.35 to 0.79, indicating that QLICD-OS could be rated as medium responsiveness. CONCLUSION: As the first osteoporosis-specific quality of life scale developed by the modular approach in China, the QLICD-OS showed good reliability, validity and medium responsiveness, and could be used to measure quality of life in osteoporosis patients.

Cross-cultural adaptation and psychometric evaluation of the social frailty scale in Iranian older adults.

BACKGROUND: Social frailty is a holistic concept encompassing various social determinants of health. Considering its importance and impact on health-related outcomes in older adults, the present study was conducted to cross-culturally adapt and psychometrically evaluate the Social Frailty Scale in Iranian older adults in 2023. METHODS: This was a methodological study. The translation and cross-cultural adaptation of the Social Frailty Scale 8-item (SFS-8) was conducted according to Wild's guideline. Content and face validity were assessed using qualitative and quantitative methods. Then, 250 older adults covered by comprehensive health centers were selected using multistage random sampling. Participants completed the demographic questionnaire, the Abbreviated Mental Test score, the SFS-8, and the Lubben Social Network Scale. Construct validity was assessed by principal component analysis (PCA) and known-group comparisons. The Mann‒Whitney U test was used to compare social frailty scores between the isolated and non-isolated older adults. Internal consistency, equivalence, and stability were assessed using the Kuder-Richardson method, the intraclass correlation coefficient (ICC), the standard error of measurement (SEM), and the minimum detectable change (MDC). The ceiling and floor effects were also assessed. The data were analyzed using JASP 0.17.3. RESULTS: The ratio and index of content validity and the modified kappa coefficient of all the items were 1.00. The impact score of the items was greater than 4.6. PCA identified the scale as a single component by removing two questions that could explain 52.9% of the total variance in the scale score. The Persian version of the Social Frailty Scale could distinguish between isolated and non-isolated older adults (p < 0.001). The Kuder-Richardson coefficient, ICC, SEM, and MDC were 0.606, 0.904, 0.129, and 0.358, respectively. The relative frequencies of the minimum and maximum scores obtained from the scale were 34.8 and 1.2, respectively. CONCLUSIONS: The Persian version of the Social Frailty Scale (P-SFS) can be used as a valid and reliable scale to assess social frailty in Iranian older adults.

Development of a real-world simulated instrument for evaluating visuospatial working memory: a preliminary psychometric study on older adults.

BACKGROUND: A prevalent challenge in neuropsychological assessment, particularly when utilizing instruments designed for controlled laboratory environments, is that the outcomes may not correspond to an individual's real-life status. Accordingly, assessments of visuospatial working memory (VSWM) conducted in such settings might fail to capture certain facets of this function, as it operates in real life. On the other hand, entirely ecological assessments may risk compromising internal validity. This study aimed to develop an intermediate mode of assessment that measures VSWM in older adults by employing a setting, a task, and a response format that aligns closely with both laboratory and ecological assessments. Furthermore, a preliminary investigation was carried out to study the variations in spatial cognition among different demographic groups. METHODS: In a two-session study, 77 healthy older adults, eight patients with mild cognitive impairment (MCI), and seven patients with Alzheimer's disease (AD) were recruited to complete the wayfinding questionnaire (WQ), the Corsi block-tapping task (CBTT), and the Spatial Memory Table (SMT). The SMT is a novel instrument developed specifically for this study, aiming to provide a more accurate measure of VSWM performance in older adults' everyday life. Test-retest and split-half reliabilities, as well as the face, content, concurrent, convergent, and known-groups validities, were analyzed to investigate the psychometric properties of the SMT. RESULTS: The analyses were mainly centered on studying the psychometric properties of the SMT. Test-retest reliability (r = .753, p < .001) and split-half reliability (ρSC = 0.747) were found to be acceptable. Concurrent validity using CBTT (r = .264, p = .021), convergent validity using WQ subscales (navigation and orientation: r = .282, p = .014; distance estimation: r = .261, p = .024), and known-groups validity using the SMT scores among people with MCI and AD (χ2 = 35.194, df = 2, p < .001) were also indicative of the instrument's good validity. Data analysis also revealed acceptable levels of face validity (U = 4.50; p = .095) and content validity (CVR ≥ 0.60). As a result of comparing VSWM and wayfinding variables across genders and education levels, a significant difference was observed for navigation and orientation and spatial anxiety between women and men (p < .05). None of the variables were different among education levels. CONCLUSION: The SMT was found to be a reliable and valid tool for measuring VSWM performance in older adults. Given these findings, the SMT can be regarded as a measure that sufficiently approximates both laboratory and real-life demands for VSWM. Additionally, the instrument demonstrated a preliminary acceptable capacity to differentiate between healthy individuals and those with MCI and AD.

The psychometric properties of the Six-Spot Step Test - a systematic review using the COSMIN guidelines.

OBJECTIVE: Accurate and reliable balance measures are important for prescribing fall prevention treatments and monitoring their effectiveness. Thus, we aimed to systematically review the psychometric properties of the Six-Spot Step Test, an increasingly used measure of dynamic balance. DATA SOURCES: A literature search using the free-text term "Six-Spot Step Test" was performed on 12 February 2024, in Medline, Embase, Rehabilitation & Sports Medicine and SPORTDiscus. Eligibility criteria were adults aged 18 or more, trials evaluating the psychometric properties of the Six-Spot Step Test, and English-language articles. Conference abstracts were excluded. REVIEW METHODS: Two investigators screened and selected data independently and assessed the methodological quality and evidence using the COSMIN Risk of Bias checklist and modified GRADE approach. One investigator extracted study characteristics such as design, population and psychometric properties. RESULTS: Of the 159 articles identified, 16, evaluating multiple measurement properties, were included in the final analysis. A total of 1319 people participated, including people affected by Stroke, multiple sclerosis, Parkison's disease, chronic inflammatory polyneuropathy and older adults with balance problems. Eight articles assessing reliability (n = 618, intraclass correlations coefficient ≥0.7, minimal detectable change = 22%) and 12 construct validity (n = 1082, 83% true hypothesis, area under the curve >0.7) exhibited sufficient methodological quality with high-level evidence, while two studies (n = 167) examining responsiveness showed very low evidence. CONCLUSION: Apart from responsiveness, robust evidence supports the reliability and validity of the Six-Spot Step Test for assessing dynamic balance in a specific group of individuals with neurological diseases and older adults. Further, it is considered feasible for clinical use.

ICD-11 post-traumatic stress disorder and complex post-traumatic stress disorder in mental health support-seeking former-serving Australian defence force veterans.

BACKGROUND: ICD-11 complex post-traumatic stress disorder is a more severe condition than post-traumatic stress disorder, and recent studies indicate it is more prevalent among military samples. In this study, we tested the psychometric properties of the International Trauma Questionnaire, assessed the relative prevalence rates of post-traumatic stress disorder and complex post-traumatic stress disorder in the sample population and explored relationships between complex post-traumatic stress disorder and post-traumatic stress disorder and a range of risk factors. METHODS: Survey participants (N = 189) were mental health support-seeking former-serving veterans of the Australian Defence Force (ADF) recruited from primary care. Confirmatory factor analysis was used to test the factorial validity of the International Trauma Questionnaire. RESULTS: The latent structure of the International Trauma Questionnaire was best represented by a two-factor second-order model consistent with the ICD-11 model of complex post-traumatic stress disorder. The International Trauma Questionnaire scale scores demonstrated excellent internal reliability. Overall, 9.1% (95% confidence interval = [4.8%, 13.5%]) met diagnostic requirements for post-traumatic stress disorder and an additional 51.4% (95% confidence interval = [44.0%, 58.9%]) met requirements for complex post-traumatic stress disorder. Those meeting diagnostic requirements for complex post-traumatic stress disorder were more likely to have served in the military for 15 years or longer, had a history of more traumatic life events and had the highest levels of depression, anxiety and stress symptoms. CONCLUSION: The International Trauma Questionnaire can effectively distinguish between post-traumatic stress disorder and complex post-traumatic stress disorder within primary care samples of Australian Defence Force veterans. A significantly greater proportion of Australian Defence Force veterans met criteria for complex post-traumatic stress disorder than post-traumatic stress disorder. Australian military mental health services should adopt the International Trauma Questionnaire to routinely screen for complex post-traumatic stress disorder and develop complex post-traumatic stress disorder specific interventions to promote recovery in Australian Defence Force veterans with complex post-traumatic stress disorder.

Factor Analysis and Validation of the Disturbing Dream and Nightmare Severity Index in an Inpatient Sample.

STUDY OBJECTIVES: The Disturbing Dream and Nightmare Severity Index (DDNSI) has been used widely in research and clinical practice without psychometric evidence supporting its use in clinical samples. The present study aimed to explore and confirm the factor structure of the DDNSI in an inpatient sample. We also sought to test the measure's construct validity. METHODS: Two samples of U.S. inpatients including adult (N = 937) and adolescent (N = 274) participants provided data on nightmares (i.e. DDNSI), sleep quality (i.e. the Pittsburgh Sleep Quality Index) and related psychopathology symptoms (e.g. depression, posttraumatic stress disorder, anxiety). RESULTS: Exploratory and confirmatory factor analyses found the six original items of the DDNSI to load onto a single latent factor. CONCLUSIONS: The DDNSI was found to be a valid measure of nightmare frequency and distress, as it was significantly correlated with the items related to disturbing dreams, and the DDNSI was able to differentiate between nightmares and psychopathology symptoms. Though this research comes nearly two decades after the initial creation and use of the DDNSI, it provides a foundation for the scientific rigor of previous and future studies on nightmares using the DDNSI.

A therapist-administered self-report version of the Walking Index for Spinal Cord Injury II (WISCI): a psychometric study.

OBJECTIVE: To develop a self-report version of the Walking Index for Spinal Cord Injury II (WISCI II) and to test its reliability and validity. STUDY DESIGN: Psychometric study. SETTING: Spinal cord injury (SCI) rehabilitation centres in Australia and Italy. PARTICIPANTS: Eighty people with SCI were recruited from a sample of convenience. METHODS: Two self-report versions of the WISCI II were developed. Both versions were administered in English at the Australian site, and in Italian at the Italian site through an online platform. The format of the first self-report version (SR-V1) was similar to the original face-to-face WISCI II. The second self-report version (SR-V2) had more questions, but each question required participants to focus on one aspect of walking at a time. Participants completed SR-V1 and SR-V2 with assistance from research physiotherapists on two separate occasions, three to seven days apart. The original WISCI II was then administered through a face-to-face assessment by an independent physiotherapist. The intra-rater reliability and validity of SR-V1 and SR-V2 were determined with intraclass correlation coefficients (ICC) and percent close agreements. RESULTS: The data from the Australian and Italian sites were pooled. The validity and reliability of the two self-report versions were very similar, with SR-V2 performing slightly better than SR-V1. The ICC (95% confidence interval) of SR-V2 was 0.87 (0.81-0.92). The ICC reflecting the agreement between the self-report and the face-to-face WISCI was 0.89 (0.84-0.93). CONCLUSION: Both versions of the self-report WISCI II provide a reasonable substitute for a face-to-face assessment although therapists preferred SR-V2.

Translation and validation of prolonged grief disorder (PG-13) scale in Urdu among bereaved adolescents with intellectual disability.

BACKGROUND: The study aimed to translate and validate the Prolonged Grief Disorder (PG-13) scale from English into Urdu language. This involved examining its psychometric properties, evaluating its factor structure and assessing both convergent and discriminant validity. The study was conducted within the cultural context of Pakistan and focused on the assessment of manifestations of grief, including symptoms of prolonged grief, in adolescents with mild-to-moderate intellectual disability (ID). The PG-13 scale was selected for this study due to its demonstrated accuracy in measuring prolonged grieving symptoms in bereaved population. METHOD: A total of 140 adolescents, aged 10-19 years according to the World Health Organization (WHO) 2018 criteria, were selected from 14 cities in Pakistan. These participants had lost loved ones within the time span of the last 4 years. The WHO (2018) guidelines for translation, adaptation, and validation were followed. RESULTS: The findings suggest that the translated and validated PG-13 scale has adequate psychometric properties, with Cronbach alpha coefficient of .97. Confirmatory factor analysis supports a single-factor structure for the scale, with factor loadings ranging from .80 to .95. CONCLUSION: The PG-13 Urdu version is a reliable and validated scale available for assessing grieving symptoms in the Pakistani context.

Measuring older adults' wellbeing when transitioning into assisted living facilities: a confirmatory factor analysis of the Mueller assessment of transition (MAT).

OBJECTIVES: Older adults' wellbeing during the transition into an assisted living facility (ALF) is not well understood and may influence their wellbeing. The Mueller Assessment of Transition (MAT) was created to measure the impact of transition on older adults' wellbeing. Early developmental testing of the MAT revealed a hypothesized model with two constructs (adjustment strategies and constraints to wellbeing). Therefore, the purpose of this study was to confirm the factor structure of the MAT with a representative sample of older adults transitioning into ALFs. METHODS: In a nationwide sample, 108 older adult participants completed the MAT to measure wellbeing when relocating into ALFs. Confirmatory factor analysis (CFA) assessed the structural validity of the MAT. Internal consistency was evaluated, and chi-square tests of association for regional differences in MAT scores were also conducted. RESULTS: The CFA produced strong fit indices to confirm the hypothesized 2-factor (constraints to wellbeing and adjustment strategies) model of the MAT. Cronbach's alpha for the internal consistency was 0.784 and chi-square test indicated no significant regional differences. CONCLUSION: The MAT was established as a valid and reliable standardized assessment. Implications for using the MAT as a tool to measure older adults' wellbeing and future research are discussed.

Evidence of validity and reliability of the Colombian version of Addenbroke's Cognitive Examination Revised (ACE-R).

OBJECTIVE: The purpose of this study is to provide evidence that supports the validity and reliability of the Colombian version of the Addenbrooke's Cognitive Examination Revised (ACE-R) in comparison to the MMSE at assessing and finding patients with Mild Cognitive Impairment (MCI). Additionally, the study aims to determine the optimal cut-off scores based on the age of a population with a low education level. METHOD: This study included 314 individuals (235 participants diagnosed with MCI and 79 cognitively healthy) who live in two different rural departments (states) in Colombia. The participants were recruited for this study through community clubs for the older adults. Most of the individuals were female (236), the average age was 65.95 years of age (SD= 7.8), and the average education level was of 3.78 years (SD = 1.79). It is important to note that the sample only included people with a maximum of 6 years of schooling. RESULTS: A ROC analysis indicated that the ACE-R is more effective than the MMSE at evaluating and finding MCI individuals within the three groups. The cut-off points for the Under 60 years of age group was 83.50 (sensitivity 0.880% and specificity 0.632%); 61-69 years of age 80.50 (sensitivity 0.714% and specificity 0.677%); and Over 70 years of age was 79.50 (sensitivity 0.750% and specificity 0.659%). The internal consistency analysis with MacDonald's Ω determined reliability indicators ≥70 in the ACE-R, except for the age range of 61 to 69 years. CONCLUSION: The Colombian version of the ACE-R demonstrates to be a valid and reliable global cognitive screening tool. It is effective at discerning MCI individuals from healthy within a group of participants with a low education level.
