Validity of the Central Sensitization Inventory compared with traditional measures of disease severity in fibromyalgia

OBJECTIVE

The goal of this study was to explore additional evidence of convergent and discriminant validity of the Central Sensitization Inventory (CSI) in a large sample of subjects with fibromyalgia (FM).

METHODS

Patients were consecutively enrolled for a cross-sectional assessment comprehensive of three FM-specific measures (the revised Fibromyalgia Impact Questionnaire [FIQR], the modified Fibromyalgia Assessment Status [modFAS], and the Polysymptomatic Distress Scale [PDS]) and of CSI. To test the convergent validity, the Spearman's rho was used to measure the degree of correlation between the variables CSI and the FM-specific measures. To assess discriminant validity, CSI scores were grouped according to FIQR disease severity states, and differences between these groups studied with the Kruskal-Wallis test. Interpretative cutoffs were established with the interquartile reconciliation approach.

RESULTS

The study included 562 FM patients, 199 (35.4%) were classified as having central sensitization syndrome (CSI ≥40). CSI was largely correlated with modFAS (ρ = 0.580; p < 0.0001), FIQR (ρ = 0.542; p < 0.0001), and PDS (ρ = 0.518; p < 0.0001). The differences between the CSI scores in accordance with the FIQR were significant (p < 0.000001). CSI cutoffs proposed for FM: 21 between remission and mild severity, 30 between mild and moderate severity, 37 between moderate and severe disease, and 51 between severe and very severe disease.

CONCLUSION

The current study successfully showed additional evidence of the convergent and discriminant validity of the CSI in FM patients.

Developing and establishing the psychometric properties of the Strathclyde Citizenship Measure: A new measure for health and social care practice and research

There has been increasing interest and research attention towards citizenship-based practices and care within health and social care settings. A framework for implementing citizenship-based interventions has helped support the participation in society of persons who have experienced major life disruptions. Yet, having ways to measure the impact of citizenship 'in action' within specific socio-cultural contexts has proved challenging. We report on the development of the Strathclyde Citizenship Measure (SCM) which seeks to establish a psychometrically sound measure of citizenship that is relevant to the Scottish context. We outline the three phases of developing the SCM: (1) item generation, (2) item reduction and piloting, and (3) measure validation. Having generated items for the SCM using concept mapping techniques, we piloted it with 407 participants who completed an online survey of a 60-item version of the SCM. The aims were to assess the validity of the items and reduce the number of items using principal components analysis for the final measure. This resulted in a 39 item SCM. We then sought to establish the psychometric properties of this shorter version of the SCM through testing its reliability, convergent, concurrent and discriminant validity. The 39 item SCM was administered online to 280 Scottish residents along with additional measures including the Warwick-Edinburgh Mental Well-being Scale (WEMWBS), the Depression, Anxiety and Stress Scale (DASS21), the Sense of Belonging Instrument (SOBI-A); the Big Five Personality Inventory (Shortened Version; BFI-10) and the Personal Social Capital Scale (PSCS-16). The factor structure and dimensionality of the SCM was examined using exploratory factor analysis and it was found to be reliable and valid. This paper explores the potential for the application of the SCM across health and social care settings and identifies future work to develop citizenship tools to facilitate dialogues about citizenship across health and social care practice settings.

Development and Validation of the Minnesota Assessment of Pharmacogenomic Literacy (MAPL)

Ensuring that patients have an adequate understanding of pharmacogenomic (PGx) test results is a critical component of implementing precision medicine into clinical care. However, no PGx-specific validated literacy assessment has yet been developed. To address this need, we developed and validated the Minnesota Assessment of Pharmacogenomic Literacy (MAPLTM). Foundational work included a scoping review of patient and general public attitudes and experiences with pharmacogenomic testing, three focus groups, readability assessments, and review by experts and members of the general public. This resulted in a 15-item assessment designed to assess knowledge in four domains: underlying concepts, limitations, benefits, and privacy. For validation, 646 participants completed the MAPL as a part of a larger survey about pharmacogenomic research and statewide PGx implementation. Two items were deemed to be “too easy” and dropped. The remaining 13 items were retained in the final MAPL with good internal reliability (Cronbach’s alpha = 0.75). Confirmatory factor analysis validated the four-domain construct of MAPL and suggested good model performance and high internal validity. The estimated coefficient loadings across 13 questions on the corresponding domains are all positive and statistically significant (p < 0.05). The MAPL covers multiple knowledge domains of specific relevance to PGx and is a useful tool for clinical and research settings where quantitative assessment of PGx literacy is of value.

Characteristics of anatomic and reverse total shoulder arthroplasty patients who achieve ceiling scores with 3 common patient-reported outcome measures

BACKGROUND

Legacy shoulder outcome scores have postoperative ceiling scores effects when quantifying clinical outcomes for anatomic (aTSA) and reverse (rTSA) total shoulder arthroplasty patients. This study uses data from an international database of a single shoulder prosthesis using data from 30 different clinical sites to quantify and compare the percentage of aTSA and rTSA patients achieving postoperative ceiling scores with multiple outcome measures and defines the patient demographics, comorbidities, implant, and operative parameters associated with ceiling scores for each outcome measure.

METHODS

Clinical outcomes for 1817 aTSA and 2635 rTSA patients between 2007 and 2019 were quantified with the American Shoulder and Elbow Surgeons Standardized Shoulder Assessment Form (ASES), Simple Shoulder Test (SST), the University of California, Los Angeles (UCLA), Constant, and Shoulder Arthroplasty Smart (SAS) scores. The number of aTSA and rTSA patients with ceiling scores were calculated and sorted into those that achieved ceiling scores with the SST, ASES, and UCLA measures and compared to patients without ceiling scores. A univariate and multivariate analysis then identified the patient demographics, comorbidities, and implant and operative parameters associated with ceiling scores for each outcome measure.

RESULTS

aTSA patients achieved ceiling scores at a significantly greater rate than rTSA patients for all outcome measures, except SAS. The SST score was the most susceptible to ceiling scores (aTSA = 43.4%, rTSA = 34.1%, P < .0001), followed by the ASES (aTSA = 23.7%, rTSA = 13.3%, P < .0001) and UCLA (aTSA = 22.2%, rTSA = 10.6%, P < .0001) scores. Ceiling scores were least likely with the Constant (aTSA = 0.4%, rTSA = 0%, P = .0060) and SAS (aTSA = 0.1%, rTSA = 0%, P = .0750) scores. Male patients had a significantly higher ceiling score rate than female patients using the SST and ASES scores, and no differences in ceiling score rates were observed with the UCLA, Constant, or SAS scores. Finally, we identified numerous patient demographic, comorbidity, implant, and operative parameters associated with SST, ASES, and UCLA ceiling scores for aTSA and rTSA patients.

DISCUSSION

Postoperative ceiling scores occur at a high rate for aTSA and rTSA patients with the SST, ASES, and UCLA scores. Those most susceptible to ceiling scores are aTSA patients treated with cage glenoids, aTSA patients of lower body mass index, rTSA patients of male gender, rTSA patients with osteoarthritis diagnosis, and rTSA patients with subscapularis repair. Clinical researchers should consider using alternative scores, such as the SAS score, to ensure a more normalized distribution of data and more accurately quantify aTSA and rTSA outcomes.

Attitudes and practices towards vital signs monitoring on paediatric wards: Cross-validation of the Ped-V scale

PURPOSE

To develop and psychometrically test an instrument measuring the attitudes and practices towards vital signs (VS) monitoring in nurses caring for children on paediatric wards (Ped-V scale).

DESIGN AND METHODS

This is a multicentre cross-validation study with a cross-sectional design. The Ped-V scale was developed by adapting the V-scale to the paediatric context and administered to a convenience sample of clinical nurses working in paediatric wards from January to May 2020. The content validity of the Ped-V scale was evaluated by a group of 10 experts. The psychometric properties of the scale were tested through Exploratory Factor Analysis (EFA) and Confirmatory Factor Analysis (CFA).

RESULTS

Overall, 10 Italian hospitals participated in the study, and 640 questionnaires were completed (87% female). At EFA a 30-item version of the scale and four factors emerged. This solution was confirmed at CFA: F1) 'Inaccuracy of VS monitoring and workload'; F2) 'Clinical competence and communication'; F3) 'Standardization and protocol adherence'; F4) 'Misconceptions about key indicators'. Cronbach's alpha ranged between 0.63 and 0.85.

CONCLUSIONS

The Ped-V scale is valid and reliable for use in the paediatric context to identify barriers concerning nurses' self-efficacy, competences, and knowledge of clinical indicators of paediatric critical deterioration, attitudes towards accuracy, standardization, communication to senior team members and the appropriate use of technology in paediatric VS monitoring.

PRACTICE IMPLICATIONS

The Ped-V scale may assist in identifying gaps in nurses' attitudes and devising strategies to change nurses' beliefs, knowledge, skills and decreasing individual, local cultural or organizational barriers towards VS monitoring.

Development and psychometric validation of new questionnaires assessing experienced discrimination and internalised stigma among people with Covid-19

AIMS

To develop and validate two new standardised measures assessing, respectively, experienced discrimination (Covid-19 Experienced DISCrimination scale, CEDISC) and internalised stigma (COvid-19 INternalised Stigma scale, COINS) in people who had been infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) or had developed coronavirus disease 2019 (Covid-19) disease.

METHODS

Both the CEDISC and the COINS were developed in Italian and tested for ease of use, comprehension, acceptability, the relevance of items and response options within a focus group session. Online cross-sectional validation survey was conducted among adults infected with SARS-CoV-2 or who developed Covid-19 disease, members of a closed Facebook discussion group in Italy. Exploratory factor analysis (EFA) with Promax oblique rotation; the Kaiser-Meyer-Olkin (KMO) measure of sampling adequacy and the Bartlett's test of sphericity were used to assess the suitability of the sample for factor analysis. Reliability was assessed as internal consistency using Cronbach's alpha and as test-retest reliability using weighted kappa and intraclass correlation coefficient (ICC). Precision was examined by Kendall's tau-b coefficient.

RESULTS

Overall, 579 participants completed the CEDISC, 519 also completed the COINS, 155 completed the retest for both scales after two weeks. The 12 items of the CEDISC converged over a 2-factor solution ('social life' and 'close relations') accounting for 49.2% of the variance (KMO = 0.894; Bartlett's test p < 0.001); the 13 items of the COINS converged over a 3-factor solution ('self-perception', 'close relations' and 'social life') accounting for 67.7% (KMO = 0.827; Bartlett's test p < 0.001). Cronbach's α was 0.848 for the CEDISC, and 0.837 for the COINS. The CEDISC showed three items (25%) with kappa between 0.61 and 0.80 and seven (58.4%) between 0.41 and 0.60, with only two items scoring 0.21 and 0.40; the COINS had ten items (76.9%) with kappa ranging from 0.41 to 0.60, and three items below 0.31. ICC was 0.906 (95% CI, 0.871-0.932) for the, CEDISC and 0.860 (95% CI, 0.808-0.898) for the COINS. Kendall's tau-b ranged from 0.360 to 0.556 (p < 0.001) for the CEDISC and from 0.290 to 0.606 (p < 0.001) for the COINS.

CONCLUSIONS

Both the CEDISC and the COINS are two valid and reliable scales to be used in studies examining the role of stigma and discrimination of people infected with SARS-CoV-2 and Covid-19 patients, and in research evaluating interventions designed to mitigate stigma in this population.

Finalization and Validation of Questionnaire and Algorithm of SPUR, a New Adherence Profiling Tool

Purpose

The SPUR (Social, Psychological, Usage and Rational) Adherence Profiling Tool is a recently developed adaptive instrument for assessing key patient-level drivers for non-adherence. This study describes the SPUR questionnaire's finalization and psychometric evaluation.

Patients and Methods

Data were collected through an online survey among patients with type 2 diabetes included by general practitioners and diabetologists in France. The survey included four questionnaires, SPUR and three validated adherence measures: BMQ, MARS and ACCEPT. Item-level analysis and a partial credit model (PCM) were performed to refine the response option coding of SPUR items. The final item selection of SPUR was defined using a PCM and a principal component analysis (PCA). Construct validity, concurrent validity and known-groups validity were assessed on the final SPUR questionnaire.

Results

A total of 245 patients (55% men, mean age of 63 years) completed the survey remotely and were included in this analysis. Refining response option coding allowed a better discrimination of patients on the latent trait. After item selection, a short, an intermediate, and a long form composed the final SPUR questionnaire. The short form will be used to screen patients for risk and then the other forms will allow the collection of further information to refine the risk assessment and decide the best levers for action. Results obtained were supportive of the construct validity of the forms. Their concurrent validity was demonstrated: moderate to high significant correlations were obtained with BMQ, MARS and ACCEPT scores. Their known-groups validity were shown with a logical pattern of higher scores obtained for patients considered non-adherent and significant differences between the scores obtained for patients considered adherent versus non-adherent.

Conclusion

SPUR is a valid tool to evaluate the risk of non-adherence of patients, allowing effective intervention by providing insights into the respective individual reasons for lack of adherence.

An Evaluation of the Body Dysmorphic Disorder Symptom Scale as a Measure of Treatment Response and Remission in Psychotherapy and Medication Trials

The Body Dysmorphic Disorder Symptom Scale (BDD-SS) is a self-report tool that captures an array of representative behavioral and cognitive symptoms commonly displayed by individuals with BDD. The BDD-SS is regularly used among experts in the field, though its utility as a measure of treatment response has not yet been formally evaluated. Results from two clinical trials of BDD treatment were pooled from an archived database to create a sample of 220 BDD participants who received either psychosocial or medication-based interventions for BDD. We used baseline BDD-SS scores to describe psychometric properties, baseline correlations with other scales to examine the content validity of the BDD-SS, and longitudinal symptom data to evaluate capacity to detect clinically relevant change. Results indicated that the BDD-SS has good psychometric properties and is able to detect symptom change over time, although it showed lower rates of reliable change with treatment relative to the gold standard rater-administered Yale-Brown Obsessive-Compulsive Scale Modified for BDD (BDD-YBOCS). The BDD-SS offers meaningful information about treatment response in a self-report format and may be particularly useful to employ in clinical practice settings as a means of gathering symptom and treatment response data via self-report when rater-administered interviews are not feasible, although it may underestimate the extent of improvement with treatment.

Validation of the Modified Thai Cancer Survivor's Unmet Needs (T-CaSUN) for Cholangiocarcinoma Patients

Background:

Cancer survivors frequently experience of unmet demands that are linked to psychological illness, anxiety, and quality of life. Cholangiocarcinoma (CCA) survivors, on the other hand, still lack of validated tool to assess their particular requirements. The aims of this study were to adjust the Cancer Survivors’ Unmet Need Scale (CaSUN) to a shorter form and to examine its psychometric scale-specific features for the Thai CCA survivors.

Methods:

This cross-sectional study recruited 231 CCA survivors and randomly split them into 2 groups (group 1, n =115, and group 2, n =116). Firstly, we modified and translated the CaSUN to ensure Thai cultural adaptation. Secondly, we used the statistical methods to reduce some items, then an exploratory factor analysis (EFA) using group 1 to explore the factor structure of the T-CaSUN was done. Finally, a confirmatory factor analysis (CFA) using group 2 was conducted to confirm the modified structure suggested by the EFA and to test for the construct validity of the T-CaSUN.

Results:

Participants consisted of 231 CCA survivors. EFA and CFA organized the four components construct T-CaSUN, which included intensive care, information, relationship, and medical care. The T-CaSUN’s internal reliability was good (Cronbach’s alpha was 0.75). Furthermore, construct validity was linked to bodily consequences, anxiety and depression, support care needs, stage of cancer, and age. For assessing unmet needs among CCA survivors in Thailand, the T-CaSUN exhibited acceptable reliability and validity.

Conclusion:

The T-CaSUN demonstrated acceptable reliability and validity for assessing unmet needs among CCA caregivers in Thailand. This short form measurement can assist healthcare practitioners in providing successful individualized care by focusing on the particular requirements of these survivors.

SIBAT-A Computerized Assessment Tool for Suicide Ideation and Behavior: Development and Psychometric Properties

OBJECTIVE

Most assessments of suicidal ideation and behavior (SIB) are limited by reliance on a single assessor, typically a clinician or patient, with scant detail on patient-related drivers of SIB and inability to detect rapid change in SIB. Furthermore, many techniques do not include a semistructured interview, increasing rater variability. The Suicide Ideation and Behavior Assessment Tool (SIBAT) addresses these limitations.

DESIGN

More than 30 experts in scale development, statistics, and clinical management of suicidal patients collaborated over a greater than four-year period to develop the SIBAT. Input for content and validity was received from patients, clinicians, and regulatory authorities in the United States (US) and Europe. Psychometric properties of the SIBAT were evaluated in validation studies.

RESULTS

The SIBAT is organized into eight independent patient- or clinician-rated modules with branching logic and scoring algorithms, which necessitates computerization. Patient-reported information is first captured in Modules 1 to 5. Thereafter, an experienced clinician reviews the patient's report, conducts a semistructured interview (Module 6), and assesses the patient's suicide risk (Module 7) and optimal antisuicide management (Module 8). Input from cognitive interviews of diverse adult, adolescent, and clinician participants was incorporated into the final version of the SIBAT. Psychometric testing demonstrated good inter-rater reliability (intraclass coefficient range: 0.68-0.82), intra-rater reliability (weighted-kappa range: 0.64-0.76), and concurrent validity with other instruments for assessing SIB.

CONCLUSION

Patient- and clinician-based assessments and the psychometric studies summarized in this report support the validity and reliability of the SIBAT for capturing critical information related to assessment of SIB in adolescents and adults at risk for suicide.

Influence of psoriasis lesions' location and severity on psychosocial disability and psychopathology. Observational study and psychometric validation of the SAPASI Portuguese version

OBJECTIVES

The psychosocial impact of psoriasis is well documented. However, the contributing role of clinical disease characteristics is not satisfactorily explored. This study aimed to validate the Self-administered Psoriasis Area and Severity Index (SAPASI) to a Portuguese population (SAPASI-PT) and to perform its cross-validation, assessing how the results will generalize to an independent data set, with the Psoriasis Area and Severity Index (PASI), in order to assess the influence of psoriasis' severity on psychosocial disability and psychopathology.

METHODS

A cross-sectional study with 228 patients with psoriasis was carried out. Data was collected through a sociodemographic and clinical questionnaire, SAPASI-PT, the Psoriasis Disability Index (PDI) and the Brief Symptoms Inventory (BSI). The cultural and linguistic adaptation of SAPASI to a Portuguese version and the cross validation with PASI was carried out. Multiple associations between psychosocial disability, psychopathology and severity, discomfort and location of lesions were investigated through logistic regression models.

RESULTS

A good adjustment model for SAPASI-PT is found. Also, associations between psychosocial disability, psychopathology and the psoriasis severity and discomfort are found. The existence of lesions is positively associated with the severity of the disease. Patients with lesions in hands or genitals are those reporting a greater discomfort. The presence of lesions in hands is positively associated with PDI, i.e., with leisure and with treatment, marginally. Additionally, patients scoring higher in the personal dimension are found to have a significantly greater percentage of lesions in the genitals.

CONCLUSIONS

The psoriasis severity and location of lesions are important determinants of patients´ quality of life. Lesions on face, hands and genitals are associated with a higher impact on psychosocial wellbeing of patients. Psychological counselling should be considered within psoriasis treatment context in patients with the described disease manifestations.

Psychometric Properties of the Thai Version of Supportive Care Needs Survey-Partners and Caregivers (T- SCNS-P&C) for Cholangiocarcinoma Caregivers

Background:

Unmet needs of cancer patients and caregivers are also closely linked with patients and their family well-being. Identifying and focusing on caregivers’ unmet need have been recommended to reduce their burden and improve their quality of life (QOL). This study aimed to evaluate the psychometric properties of the Thai version of Supportive Care Needs Survey for Partners and Caregivers (T-SCNS-P&C) among Cholangiocarcinoma (CCA) caregivers.

Methods:

The T-SCNS-P&C was developed using standardized translation methodology. A total of 231 CCA caregivers completed the T- SCNS-P&C. The internal consistency of the scale was examined with Cronbach’s alpha. Construct validity was analyzed using Pearson correlations coefficient with the physical effects, stage, anxiety and depression, age, and education level. To assess the factorial validity of the T-SCNS-P&C, confirmatory factor analysis (CFA) was performed.

Results:

The T- SCNS-P&C indicated good readability and high content validity for use as an assessment tool among Thai CCA caregivers. All Cronbach’s α coefficients were above the minimum acceptable criterion of ≥0.70. For construct validity, higher physical effect scores and higher anxiety and depression scores, as well as poorer QOL scores and younger caregivers, were significantly positively associated with higher levels of unmet needs. CFA indicated that the four factor structure of the T-SCNS-P&C was a good fit to the data.

Conclusion:

The T-SCNS-P&C demonstrated acceptable reliability and validity for assessing unmet needs among CCA caregivers in Thailand. Using this simple assessment to target the individual needs of these caregivers can help healthcare professionals providing effective personalized care.

Evaluation of the Portuguese version of the London measure of unplanned pregnancy in Mozambique: A psychometric measurement study

Robust forms of measurement such as the London Measure of Unplanned Pregnancy (LMUP), which recognise the complexity of the construct of pregnancy planning/intention, are being adopted worldwide. The aim of this study was to evaluate the psychometric properties of the Mozambican Portuguese version of the LMUP. The Brazilian Portuguese interviewer-administered LMUP was culturally adapted for use in Mozambique and pre-tested with 28 women. Field testing included 524 women aged 16-42. Completion rates of LMUP items were 100%. LMUP scores 0-12 were captured. In terms of reliability (internal consistency), Cronbach's alpha was 0.90, item-rest correlations were <0.2, and all inter-item correlations were positive. In terms of construct validity, principal components analysis showed that measurement was unidimensional, confirmatory factor analysis showed good model fit, and all hypotheses were met. We conclude that the Mozambican Portuguese LMUP is reliable, valid and suitable to use in Mozambique.

The SPUR adherence profiling tool: preliminary results of algorithm development

OBJECTIVE

The SPUR (Social, Psychological, Usage, and Rational) Adherence Profiling Tool is a recently developed adaptive instrument for measuring key patient-level risk factors for adherence problems. This study describes the SPUR questionnaire's psychometric refinement and evaluation.

METHODS

Data were collected through an online survey among individuals with type 2 diabetes in the United States. 501 participants completed multiple questionnaires, including SPUR and several validated adherence measures. A Partial Credit Model (PCM) analysis was performed to evaluate the structure of the SPUR tool and verify the assumption of a single underlying latent variable reflecting adherence. Partial least-squares discriminant analyses (PLS-DA) were conducted to identify which hierarchically-defined items within each dimension needed to be answered by a given patient. Lastly, correlations were calculated between the latent trait of SPUR adherence and other patient-reported adherence measures.

RESULTS

Of the 45 candidate SPUR items, 39 proved to fit well to the PCM confirming that SPUR responses reflected one underlying latent trait hypothesized as non-adherence. Correlations between the latent trait of the SPUR tool and other adherence measures were positive, statistically significant, and ranged from 0.32 to 0.48 (p-values < .0001). The person-item map showed that the items reflected well the range of adherence behaviors from perfect adherence to high levels of non-adherence. The PLS-DA results confirmed the relevance of using four meta-items as filters to open or close subsequent items from their corresponding SPUR dimensions.

CONCLUSIONS

The SPUR tool represents a promising new adaptive instrument for measuring adherence accurately and efficiently using the digital behavioral diagnostic tool.

Spanish linguistic validation of the Self-efficacy questionnaire in communication skills

Background Self-efficacy is a critical element of social cognitive theory and refers to a person's estimation of their ability to complete a specific task. Self-efficacy scales evaluate the effectiveness of communication skills training programs. There were not validated scales in Spanish. Aims: to cross-culturally adapt the Self-efficacy questionnaire-12 scale in communication skills in Spanish, evaluate its psychometric properties, and analyse the sample's descriptive characteristics. Design: we conducted an instrumental study to develop evaluation scales. Methods: nursing students were invited to participate (N = 387). The inclusion criteria were: (1) enrolment in first or fourth academic course year; (2) not having received specific training in communication skills; and (3) understanding written and spoken Spanish fluently. A total of 334 undergraduates participated (86.3% response rate); their mean age was 21.9 years (SD = 5.8), 83.2% were female. Results: data showed high internal consistency (0.94) and a good fit to the model. The overall instrument score correlated with the attitude towards communication skills (r = 0.20; p < 0.001). Moderate communication self-efficacy scores were observed in these nursing students. Impact statement: Evaluating communication skills through self-efficacy scales allows teachers to know each student's perceived proficiency to handle communication with users safely and to understand users' needs, giving information about aspects to improve and to establish effective institutional strategies as one of the inherent characteristics of the concept of skills-based evaluation. Conclusions: The Spanish version of the Self-efficacy questionnaire-12 in communication skills was a valid and reliable instrument, essential for evaluating the perceived self-efficacy towards communication in nursing.

Adaptation to Brazilian Portuguese and Latin-American Spanish and psychometric properties of the Mental Illness Clinicians' Attitudes Scale (MICA v4)

OBJECTIVE

To describe translation to Spanish and Portuguese and adaptation of the Mental Illness Clinicians' Attitudes Scale version 4 (MICA v4).

METHODS

The questionnaire was administered to primary care physicians (PCPs) from four Latin-American countries, Brazil, Bolivia, Chile, and Cuba. The validation process included four phases: 1) translation of the questionnaire to Spanish and Portuguese; 2) assessment of face validity; 3) assessment of reliability; and 4) evaluation of construct validity with confirmatory factor analysis (CFA).

RESULTS

The study sample comprised 427 PCPs. The mean age of the Spanish-speaking sample (n = 252) was 40.1 (S.D = 9.7) years and the mean age of the Portuguese-speaking sample (n = 150) was 40.2 (S.D = 10.9) years. Both models demonstrated "appropriate" internal reliability. Total omega was 0.91 for the Spanish-speaking sample and 0.89 for the Portuguese-speaking sample. The CFA of both questionnaires showed an appropriate fit for a three-factor model (Portuguese: CFI = 0.927; TLI = 0.913; RMSEA = 0.066; Spanish: CFI = 0.945; TLI = 0.935; RMSEA = 0.068).

CONCLUSION

The Latin-American versions of the MICA v4 in Spanish and Brazilian Portuguese have appropriate psychometric properties, good internal consistency, and are applicable to and acceptable in the Latin-American context. The instrument proved its validity for collecting data on stigmatizing attitudes among health professionals in different contexts and cultures.

Patient-Reported Experience Measures in outpatient rheumatology care: a systematic review

Objectives

There is a growing acceptance of the need for routine implementation of patient-reported experience measures (PREMs) in health care. Rheumatology patients, as frequent and long-term users of care, stand to benefit from collection of experience-related data. The aim of this study was to perform a systematic review to identify and critically appraise the development and psychometric validation of PREMs in rheumatology.

Methods

Six databases were searched systematically from inception to 14 December 2020: MEDLINE, EMBASE, PsycINFO, SCOPUS, Cochrane and Google Scholar. We included articles in English that described the use or development of PREMs, with results of psychometric testing, in an adult outpatient rheumatology context. This study is registered with PROSPERO (CRD42021233819). Articles were appraised using the COnsensus Based Standards for the selection of health status Measurement Instruments (COSMIN) (i) Risk of Bias checklist and (ii) criteria for good measurement properties.

Results

The search yielded 3809 publications, and six studies met inclusion criteria. All the included studies on PREM development fulfilled COSMIN standards for 'doubtful' or 'inadequate' quality of instrument development. One study fulfilled a 'sufficient' rating for content validity, and the remainder fulfilled 'inconsistent' ratings. During validity testing, studies fulfilled between one and four of the eight COSMIN checklist criteria for good measurement properties.

Conclusion

Methodological concerns regarding instrument development and validation limit the generalizability of the existing six validated PREMs in use in rheumatology contexts. There is a need for further well-designed studies to validate existing and new PREMs in this area.

Psychometric validation of the Chinese version of the PROMIS Social Relationships Short Forms

AIM

This study aimed to culturally adapt and psychometrically validate the PROMIS Social Relationships Short Forms (PROMIS-SR) among Chinese patients with breast cancer.

DESIGN

A cross-sectional study.

METHOD

The PROMIS-SR was translated into simplified Chinese by strictly adhering to the Functional Assessment of Chronic Illness Therapy translation method and was subsequently tested among patients with breast cancer (N = 965). Eligible patients filled out the demographic information questionnaire, the PROMIS-SR, and the Functional Assessment of Cancer Therapy-Breast.

RESULTS

Confirmatory factor analysis (CFA) provided support for the original structure of the PROMIS-SR. All instruments reported strong known-group, cross-cultural and convergent validity, as hypothesized. Correlation coefficients ranged from 0.67 to 0.85, and Cronbach's α of all items were high (0.90-0.94).

Psychometric Validation of the Cardiff Wound Impact Schedule Questionnaire in a Spanish Population with Diabetic Foot Ulcer

Diabetic foot ulcers (DFU) negatively affect the quality of life (QoL) of people with diabetes. The Cardiff Wound Impact Schedule (CWIS) questionnaire has been designed to measure the QoL of people with chronic foot wounds. However, no studies have been specifically designed to validate this instrument in a Spanish population. In this prospective study, a total of 141 subjects with DFU were recruited. DFU was determined by performing physical examinations. Medical records were exhaustively reviewed to collect clinical variables. The CWIS was transculturally adapted by a group of experts and a group of patients with DFU. The SF-36 and EQ-5D generic instruments were used as reference tools. The questionnaires were administered at 7 days and 4, 12, and 26 weeks after the baseline assessment by personal interview with each of the study subjects. The psychometric properties of the instrument were assessed using statistical methods. The content validity had an average of 3.63 (90.7% of the maximum score of 4). The internal consistency of the CWIS subscales had a standardized Cronbach’s alpha range from 0.715 to 0.797. The reproducibility was moderate with an intraclass correlation coefficient (ICC) range from 0.606 to 0.868. Significant correlations between CWIS domains and SF-36 and EQ-5D subscales were observed, demonstrating a good criterion validity of the CWIS questionnaire (p < 0.001). However, the construct validity of the CWIS was not validated with a comparative fit index (CFI) of 0.69, a root mean square error of approximation (RMSEA) of 0.09, and a standardized root mean square residual (SRMR) of 0.10. The sensitivity to changes over time was optimal in the three domains (i.e., social life, well-being, and physical symptoms) (p < 0.001). In conclusion, the Spanish version of the CWIS shows acceptable psychometric properties to assess the QoL of subjects with DFU, except for its construct validity.

Psychometric Validation of the Arabic Fear of Illness and Virus Evaluation

Global infectious pandemics can affect the psychology and behavior of human beings. Several tools were developed to evaluate the psychological impact of such outbreaks. The present study aimed to examine the psychometric properties of the Arabic translated version of Fear of Illness and Virus Evaluation scale (FIVE). FIVE is a 35-item tool consisting of four subscales that measure Fears about Contamination and Illness, Fears about Social Distancing, Behaviors Related to Illness and Virus Fears and Impact of Illness and Virus Fears. The tool was translated into Arabic by using a forward-backward translation. The online questionnaire contained the following sections: demographics, FIVE, Fear of COVID-19 Scale (FCV-19S) and face validity questions. Non-probability convenient sampling technique was used to recruit participants via a mobile instant messaging application. Reliability, concurrent validity, face validity and factor analysis were examined. The data consisted of 509 adult participants who reside in Saudi Arabia. The internal consistency of the Arabic FIVE subscales was high (0.84-0.91) with strong concurrent validity indicated by positive correlations of FIVE subscales with FCV-19S. Factor analysis suggested slightly different factor structures (Fears of Getting Sick, Fears that Others Get Sick, Fears of the Impact on Social Life and Behaviors Related to Illness and Virus Fears). Our data showed a better fit using the proposed structures. The Arabic version of the FIVE showed robust validity and reliability qualities to assess fear of COVID-19 on Arabic adult population.

Pilot Validation Study on the Tavistock Relationships Observational Scale for the Assessment of the Quality of Dyadic Relationships in Couples in Which One Partner Has Dementia

BACKGROUND AND PURPOSE

Many people with dementia are cared for by their spouses. Poor quality of the dyadic relationship is a known risk factor for carer burden and mistreatment of the person with dementia. This study aimed to design and cross validate the Tavistock Relationships Observational Scale (TROS) for assessment of the quality of the relationship in such couples.

METHODS

The study was conducted within the context of the therapeutic intervention with n = 11 couples. Couples' video-recorded interactions were assessed independently by three psychologists using the 13-item TROS.

RESULTS

Cronbach alphas of the scale computed for the three raters were in the range 0.76-0.88 (on average 0.83), thus demonstrating high internal consistency of the scale. Fleiss Kappa coefficient for the three rates computed for 22 assessed videos ranged between 0.45 (moderate agreement) and 0.85 (almost perfect agreement) with 50% of coefficients being above 0.50, suggesting the good performance of the TROS in terms of yielding a satisfactory inter-rater agreement. The TROS also showed good external validity when using as validation criteria caregiving partner's burden (measured with the Zarid Burden Interview: the scales Social burden [Rho = -0.65, p = 0.021] and Role strain [Rho = -0.68, p = 0.014]), depression of the person with dementia (measured with the Cornell Scale for Depression in Dementia: Rho = -0.78, p = 0.020), and relationship satisfaction of the caregiving partner (measured with the dyadic adjustment scale: Rho = 0.52, p = 0.038). The TROS also showed a good capacity to detect the change in scores from time 1 to time 2; moreover, power analysis showed that the TROS can detect the change in scores even in very small samples (n = 5 couples).

CONCLUSIONS

The TROS may be a useful tool for a standardized assessment of the quality of dyadic relationships in couples with dementia in research, nursing, or clinical settings to assist clinical psychologist, nurses, or social workers in a preliminary evaluation of the situation of couples with dementia, to choose a suitable care or intervention, to assess the effectiveness of interventions focusing on improvement of dyadic relationships, or to assess the risk of spousal abuse or neglect of a person with dementia.

Monitoring Severity of Respiratory Syncytial Virus (RSV) in Infants and Young Children Using the Pediatric RSV Electronic Severity and Outcome Rating System (PRESORS): Results of Initial Quantitative Validation

Purpose

PRESORS ClinRO completed by clinicians and ObsRO completed by caregivers were developed to characterize the clinical course of respiratory syncytial virus (RSV) infection. This study describes preliminary analysis of PRESORS’ measurement properties using clinical trial data.

Patients and Methods

PRESORS ClinRO and ObsRO data were collected in a 28-day randomized, double-blind, Phase 1b trial of JNJ-53718678 or placebo in infants and children ≤24 months of age treated for RSV infection in hospitals. PRESORS data were scored and key psychometric properties of scores were evaluated, including ability to discriminate between known groups and to detect change over time. Time to resolution of RSV signs was explored using two responder definitions.

Results

Daily completion rates for PRESORS ClinRO and ObsRO were high for the 44 children in the study (median: 100% and 93%, respectively). Large floor effects were observed at baseline for signs of severe RSV infection that were either absent (cyanosis, fever, apnea) or rarely reported (reduced urination/dehydration, vomiting). Implausible ObsRO ratings suggested some caregivers could not accurately measure heart rate. Known-group validity was confirmed: children in poor health based on baseline ClinRO had mean baseline composite scores that were significantly worse for both ObsRO (p=0.001) and ClinRO (p<0.001) compared to those with better overall health. ObsRO (p=0.009) and ClinRO (p<0.001) composite scores were responsive to change in overall health status from baseline to Day 3. Mean scores for RSV sign dimensions decreased rapidly from baseline to Day 7 except for coughing and sleep ratings by caregivers. Time to recovery varied greatly depending on definitions used.

Conclusion

PRESORS ClinRO and ObsRO can inform endpoints and enable monitoring the clinical course of RSV in pediatric trials. Improved alignment between ClinRO and ObsRO and revisions ensuring caregivers can assess all signs will be addressed in revised PRESORS.

Validation of the Fear of COVID-19 Scale in a Sample of Pakistan's University Students and Future Directions

This study determined the psychometric validation of the English version of the Fear of COVID-19 Scale (FCV-19S). Findings demonstrated robust psychometric properties for the FCV-19S. CFA results showed that the FCV-19S was a good model fit to the data in a sample of 608 university students. The FCV-19S also showed good concurrent validity, as it was significantly and positively related to the Preventive Behaviors related to COVID-19 Scale and the Generalized Anxiety Disorder Scale as well as significantly and negatively related to the Warwick-Edinburgh Mental Well-being Scale. The scale also showed good internal consistency reliability. Further, the association of age with FCV-19S indicated that younger students experienced greater fear of COVID-19. The analyses of mean differences revealed that women as compared to men, bachelor's and master's students as compared to post-master's students, and unemployed students as compared to employed students experienced greater fear of the outbreak. Also, those suffering from severe anxiety experienced greater fear of COVID-19 followed by those suffering from moderate, mild, and minimal anxiety. Moreover, knowing someone suffering from the coronavirus, being afraid that someone close might contract the virus, and believing that the current COVID-19 situation adversely affects academic performance were linked to higher levels of fear of the pandemic. Practice implications, limitations, and avenues for future research are also discussed.

Test-Retest Reliability and Clinical and Research Validity of the 'Quality of Life Impact and Concerns' (QoLI&C) Measure

Hip dysplasia is a significant public health issue, representing the single largest cause for total hip arthroplasty in young adults. To gain insight into patient concerns and the impact of hip dysplasia on young adults, we developed a patient-centred outcome measure, the 'Quality of Life Impact and Concerns' (QoLI&C) measure. This short report provides additional evidence on test-retest reliability and suggests refinements to the measure to enhance its research and clinical utility.

Adaptation and psychometric validation of a questionnaire about organizational safety culture and climate for the Brazilian reality

Surveys are the most widely used instruments to assess safety opinions, attitudes and behaviours of workers, as a reflection of a dimensional manifestation of an organization's safety culture. The fact that there are few instruments of this nature adapted to the Brazilian reality motivated the attempt to validate tools used in Portugal in this field. The questionnaire to workers about occupational safety culture and climate (QTCCS) will be explored in this article. The main objective is to present the data from the cultural adaptation and psychometric validation process of this instrument, and it can be confirmed that this intention was properly achieved. Through a study carried out with a sample of 200 workers from a company in the northeast of Brazil, it was statistically confirmed that it is possible to maintain the factorial structure of the original instrument when applied to Brazilian workers of different characteristics.
