Psychometric assessment of a Chinese version of a mindfulness practice quality measurement tool.

Mindfulness training is increasingly popular in China. The challenge of evaluating mindfulness practice objectively and accurately has attracted research attention. However, previous studies in China focused primarily on the quantity rather than the quality of mindfulness training. The Practice Quality - Mindfulness (PQ-M) can provide a solution. Consequently, the present study aimed to validate and assess the internal consistency and construct validity of the Chinese version of the Practice Quality - Mindfulness (Ch-PQ-M) in a non-clinical sample. One hundred and sixty participants (female:81) were recruited to practice 20min of mindfulness training daily for four consecutive days and to complete the Ch-PQ-M, the State Anxiety Inventory, and the Peace of Mind Scale immediately after each mindfulness practice. The Five Facet Mindfulness Questionnaire, the Trait Anxiety Inventory, and the Positive and Negative Affect Scale were administered pre- and post- 4-day treatment. Construct validity (confirmatory factor analysis), internal consistency, test-retest reliability, predictive validity and construct validity were examined. Ch-PQ-M demonstrated acceptable internal consistency and test-retest reliability. Confirmatory factor analysis supported the established two-factor model (perseverance and receptivity). The Ch-PQ-M attention score was significantly associated with changes of trait anxiety. It improved with short-term mindfulness practice. The perseverance score consistently correlates with scores on peace of mind, state anxiety, trait anxiety, and observe and nonreactivity. The receptivity score remains consistently correlated with the nonjudging. These findings suggest that Ch-PQ-M is a valid instrument for evaluating individual mindfulness quality for a single-session practice. Our findings suggest that Ch-PQ-M (especially for the Ch-PQ-M perseverance score) has acceptable psychometric properties and is a reliable and valid instrument for assessing mindfulness practice quality in the Chinese cultural context.

Psychometric properties of the Thai version of the Simple Knee Value in patients with patellofemoral pain

Purpose This study aimed to translate the Simple Knee Value (SKV) into Thai and evaluate its psychometric properties as a single-question assessment tool. Methods The SKV was translated into Thai according to international guidelines. Psychometric properties were assessed in adults aged 18–50 years with patellofemoral pain. Participants completed questionnaires at baseline, 2 weeks, and 2 months. Results Seventy-six patients with patellofemoral pain (mean age 36.8 ± 8.3 years, 56.6% female) participated in this prospective cohort study. SKV scores were moderately correlated with those of the Knee Injury and Osteoarthritis Outcome Score–Patellofemoral Subscale (KOOS-PF) and the Anterior Knee Pain Scale (AKPS). The test-retest reliability was high, with an intraclass correlation coefficient of 0.79 (95% confidence interval: 0.65–0.88). The SKV change scores effectively differentiated between improved and unimproved patients, with a minimal important change of 12.5 points. Conclusions The SKV demonstrated acceptable psychometric properties for assessing patellofemoral pain in young to middle-aged adults. This single-question patient-reported outcome measure is simple and easy to use in daily clinical practice and can serve as an adjunctive assessment tool in patellofemoral pain research.

Basic instruments for measuring the quality of life in patients after stroke (literature review)

Improvements in drug therapy have led to an increase in the number of patients surviving after the acute period of the stroke. A significant proportion of stroke patients experience consequences such as impaired motor function, psychological and social disorders. This affects the quality of life (QoL) of patients. General and specialized tests are used to assess the QoL in patients after a stroke. The purpose of the study. Systematization of information about the main questionnaires used in assessing QoL in patients after the acute period of stroke. The search for relevant sources devoted to the topic of work was carried out in the bibliographic database Pubmed / Medline and the Google information system. The following keywords were used in the search queries: “quality of life”, “stroke”, “indicators” etc. Test names were also used as keywords. The characteristics of a number of general and specialized questionnaires that allow analyzing QoL in patients after a stroke are considered. Key practical information about the main questionnaires used abroad is summarized. Information on their applicability in domestic studies of QoL in patients who have suffered from a stroke is presented. The instruments that are most widely used in foreign practice are noted. The tests reviewed (general and specific) have usually acceptable psychometric properties (validity and reliability), although none are ideal or suitable for all situations. Continuing the development of comprehensive methods for assessing QoL in patients with stroke consequences at are best suited for everyday clinical practice remains one of the important tasks of medicine. Further development and widespread introduction of promising methods of QOL analysis into regular medical practice will increase the information content of assessments of the outcomes of therapy and rehabilitation.

To speak or not to speak? A secondary data analysis to further explore the context-insensitive avoidance scale.

Inflexibly relying on avoidance of expression may increase and perpetuate pain-related emotional distress in patients with chronic pain. The context-insensitive avoidance (CIA) scale was recently developed to measure the degree to which patients avoid expressing their pain and distress in social situations. This study explored the psychometric properties of the CIA scale in a new sample. This study uses baseline data from a treatment trial for n = 115 patients with chronic pain and co-occurring emotional distress. Reliability and construct and criteria validity were studied using the same instruments as in the original psychometric study and further explored in two new measures. A series of multiple regression analyses were conducted to assess the relationship between the CIA scale and criteria variables compared to the other psychological constructs. The CIA scale showed good reliability. Significant correlations between high scores on the CIA scale and low scores on self-compassion and activity engagement could be replicated. Significant correlations between high scores on the CIA scale and high scores of pain intensity and pain interference could also be replicated. In the exploring part of this study, validity was extended to general problems with emotion regulation and to satisfaction with life in general and contact with friends but not to satisfaction with family, partner, or sexual life. Avoidance of expression was the only significant predictor of pain intensity. This study could replicate acceptable psychometric properties of a scale measuring CIA of expression. As in the original study, avoidance of expression was associated with increased suffering. Clinically, this instrument may be used to identify patients who may otherwise remain in aggravating silence. Theoretically, it introduces the important concept of context sensitivity to the field of chronic pain. Limitations include uncertainty about causal relationships, and that several important social situations were not examined.

The Perceived Weight Stigma Scale and Weight Self-Stigma Questionnaire: Rasch analysis, confirmatory factor analysis, and network analysis among Chinese adolescents

ObjectivesThe objectives of the present study were to (i) re-evaluate and expand the psychometric properties of two weight stigma instruments—the Perceived Weight Stigma Scale (PWSS) and the Weight Self-Stigma Questionnaire (WSSQ) among a large sample of adolescents using advanced psychometric methods and (ii) examine how the different types of weight stigma (i.e., PWSS and WSSQ) are associated with psychological distress. Study designCross-sectional study. MethodsIn September 2023, a cross-sectional survey utilising convenience sampling was used to recruit 9995 adolescents (mean age = 16.36 years [standard deviation = 0.78]; 57.8% males). They completed the PWSS, WSSQ, and a measure on psychological distress. The data were analysed using Rasch analysis, confirmatory factor analysis (CFA), structural equation modelling (SEM), and network analysis. ResultsThe CFA and Rasch model results showed acceptable psychometric properties regarding factor structure, factor loading, difficulty, and infit and outfit mean squares (except Items 4 and 7 of the PWSS). There was no substantial differential item functioning for any tested items across the sex and weight categories. The CFA and SEM results showed promising validity indices with significant associations between both weight stigma scales and psychological distress (i.e., depression, anxiety, and stress). Network analysis showed inter-variable connectivity between nodes PWSS3 (“People act as if they are afraid of you”) and WSSQF7 (“I feel insecure about others’ opinions of me”). ConclusionsBoth weight stigma scales had acceptable psychometric properties and were significantly associated with psychological distress, although each assessed different types of weight stigma. This suggests that researchers and clinicians can use these scales to reliably and validly assess weight stigmas among adolescents.

Psychometric properties of Persian version of the advanced activities of daily living scale: A psychometric study on Iranian older adults

This study was conducted to determine the psychometric properties of the Persian version of an AADL scale in Iranian older adults. A total of 237 males and females aged over 60 years old were recruited. Personal information questionnaires, the CASP-19 Quality of Life, and AADL questionnaires were used for data collection. SPSS 24 and IBM AMOS 24 were used for data processing and analysis. Three factors that had eigenvalues higher than one were extracted, which explained 51.2 % of the total variances. The Cronbach α of the total score was 0.76, and it was >0.64 for each extracted factor. The goodness of fit indices indicated an acceptable fit to the data in confirmatory factor analysis. The culturally modified Persian version of the AADL scale has acceptable psychometric properties and is proper for evaluating the advanced activities of daily living in the Iranian population.

Psychometric properties of the Persian version of the workplace fun scale among nurses: a cross-sectional study

Previous research has highlighted the importance of workplace fun in enhancing employee satisfaction and performance, particularly in high-stress professions like nursing. However, a notable gap exists in understanding how workplace fun is perceived and measured among nurses in Persian-speaking countries. This study addresses this gap by translating the Workplace Fun Scale and assessing its psychometric properties among nurses. The findings will provide insights into the scale’s applicability in these contexts and pave the way for healthcare organizations to significantly explore ways to enhance nurses’ enjoyment of work in Persian-speaking countries. This survey, which involved 321 nurses from medical education centers in Ardabil, was conducted with a meticulous and rigorous methodology. Standard questionnaires collected the data, including a demographic form and the translated Workplace Fun Scale. The study examined the three aspects of workplace fun: fun activities, coworker socializing, and manager support for fun. Confirmatory factor analysis was used to validate the structure, and reliability was assessed through retest coefficients, Cronbach’s alpha coefficients, and composite reliability coefficients. The data were analyzed using SPSS version 14 and LISREL version 8.8, ensuring the highest research standards. The validity of both form and content was confirmed through translation and reverse translation. The Workplace Fun Scale showed high internal consistency and reliability, with significant Cronbach’s alpha coefficients, composite reliability, and two-week retest coefficients of 0.859, 0.885, and 0.459, respectively (all at the p < 0.01 level). Fit indices, including GFI (0.97), AGFI (0.94), CFI (0.99), NFI (0.98), TLI (0.97), and SRMR (0.04), indicated a good fit of the measurement model, confirming the validity of the scale in assessing workplace fun. The confirmatory factor analysis results indicated that the translated version of the workplace fun scale, adapted from Tews, exhibited a robust factor structure and internal homogeneity within the Iranian sample. Furthermore, the scale demonstrated positive internal validity and reliability in Persian translation. These findings suggest that the scale possesses acceptable psychometric properties, making it a valuable tool for assessing workplace fun among nurses in Persian-speaking countries.

Validation of the Multidimensional Scale of Perceived Social Support among LGBT population in Serbia

Abstract Background Social support represents the belief that one is valued, cared for, and loved by others in a social network and a lack of it may lead to adverse outcomes such as a relapse into depression or emotional distress in physically ill patients. The Multidimensional Scale of Perceived Social Support (MSPSS) is an instrument aimed to measure an individual’s perception of how much he or she receives outside social support. This study aimed to examine the validity and reliability of the Serbian version of MSPSS in a sample of LGBT population in Serbia. Methods The cross-sectional study included 504 respondents, members of the LGBT population living in Serbia. The instrument used was the MSPSS as a self-report measure, containing twelve items rated on a 7-point Likert scale. MSPSS consists of three sub-scales: Family, Friends, and Significant Others. Exploratory (EFA) and confirmatory factor analyses (CFA) were performed with two independent random samples. Results The average score on the scale of social support was 5.58±0.84 (scale of social support by family 4.62±1.41, scale of social support by friends 5.93± 1.99, and scale of social support by the significant others 6.20±0.96, respectively). The Cronbach’s alpha for the entire social support scale was α = 0.772. The three-factor structure of the MSPSS was proved with EFA and CFA. The factor loadings varied between 0.630-0.817. The three factors explained a total of 52.68% of the variance (factor 1- 28.62%, factor 2. 13.16%, factor 3- 10,90%). The three-factor model was adopted during the CFA when the three-factor model CFI (comparative fit index) was 0.969. Conclusions The MSPSS has shown good reliability, internal validity and construct validity and can be used as a convenient measure of social support among the LGBT population. Both EFA and CFA yield a three-factor structure consistent with the theory underlying the measure’s development. Key messages • The results of the study suggest that the Multidimensional Scale of Perceived Social Support has acceptable psychometric properties for use with the LGBT population. • This study supports the use of the MSPSS for assessing community-based collaboration using the three-factor model among the LGBT population.

The patient-reported outcome measure for older people living with frailty receiving acute care (PROM-OPAC): field-testing and validation

BackgroundCurrent acute healthcare service metrics are not meaningful for older people living with frailty. Healthcare knowledge, situational security, and physical and psychosocial function are important outcomes typically not collected. The use of patient-reported outcome measures (PROMs) could support these assessments. Existing instruments are not comprehensive as they typically consider function, while older people with frailty also value enablement (self-determination and security in health and healthcare). This study field-tested and validated a PROM for older people with frailty receiving acute care (PROM-OPAC) to measure enablement.MethodsPeople aged 65+ with Clinical Frailty Scale 5–8 were recruited within seventy-two hours of an emergency attendance. Iterations of the novel instrument were administered over three stages: (1) preliminary field-testing for reliability (response distribution and internal consistency) and structure (exploratory factor analysis, EFA); (2) intermediate field-testing of an improved instrument for reliability and structure; (3) final draft validation assessing reliability, structure (confirmatory factor analysis, CFA), and construct validity based on a priori hypotheses. Feasibility was appraised throughout using data completeness and response rates and times.Results241 people participated. Three items of a preliminary seven-item measure had poor response distribution or loading and were accordingly improved. The intermediate instrument had interpretability issues and three items required further improvement. The final eight-item draft had acceptable reliability (Cronbach’s alpha: 0.71), structure (two factors for self-determination and security; RMSEA: 0.065; TLI: 0.917; CFI: 0.944), and construct validity (lower scores from respondents waiting longer and requiring admission). Feasibility was promising (response rate 39%; 98% responses complete; median completion time 11 (IQR: 12) minutes).ConclusionsAdministration of the PROM-OPAC appeared feasible and the instrument had acceptable psychometric properties. Further evaluation is required to assess generalisability.

Psychometric properties of the preschool strengths and difficulties questionnaire (SDQ) in UK 1-to-2-year-olds.

The SDQ demonstrated satisfactory psychometric properties, suggesting that it may be a useful tool for the detection of early mental health difficulties, particularly externalising symptoms, even in very young toddlers. Further research is needed to validate the SDQ in younger populations and to establish cut-off scores for clinical interpretation. The implications of these findings are discussed. • Clinically significant emotional and behavioural problems can and do emerge in early toddlerhood. • Parenting interventions can reduce mental health problems. • Valid, reliable, brief, and affordable tools are needed to identify very young children who may benefit from such support. • The Strengths and Difficulties Questionnaire was found to have acceptable factor structure and psychometric properties for use with young children aged 1-2 years old in the UK. • The externalising subscale in particular shows promise as an early screening tool.

The psychometric properties of the Pearlin Mastery Scale in persons living with restless legs syndrome.

Restless Legs Syndrome (RLS) is a neurological disorder characterized by an urge to move arms and legs, commonly combined with distress, pain and motor restlessness. It can cause fragmented sleep, daytime symptoms, and decreased quality of life. Pharmacological treatment can suppress symptoms, but not cure. When challenged with illness, people may turn to their inner psychological resources such as self-esteem and mastery. The Pearlin Mastery scale was developed to study stress and coping, is commonly used in people with chronic illnesses, however, not yet validated in people with RLS. The aim was to test reliability and construct validity of the Pearlin Mastery Scale in persons with RLS. A cross-sectional postal survey including the Pearlin Mastery Scale, Restless Legs Syndrome-6 Scale, Pittsburgh Sleep Quality Index and Patient Health Questionnaire was sent out to members (n = 1500) of the national RLS association and 788 (52.5%) agreed to participate. Data were analyzed using classical test theory, Confirmatory factor analysis and Rasch measurement theory analysis. Hypothesis testing for construct validity was done by bivariate correlation analyses. Most respondents were women (65%), retired (71%) and had a mean-age of 70.8 years (SD 11.4). The 7-item version of the Pearlin Mastery Scale showed poor fit to the one factor model. After omitting the two positively worded items (i.e., item 4 and 6), the 5-item version was found to be unidimensional, with satisfactory internal consistency. However, all items showed considerable ceiling effects. No measurement variance was seen regarding age-groups or sex. Higher level of mastery was moderately correlated with less depressive symptoms but only weakly correlated to RLS-related sleep problems. The 5-item version of the Pearlin Mastery Scale is suggested to be used in persons with RLS due to its acceptable psychometric properties. The instrument could be applied as an outcome measure for behavioral change interventions aiming to support mastery in RLS.

Sleep-related measurements to assess sleep disturbances among people living with dementia in nursing homes: a systematic review.

There is a high prevalence of sleep disturbances among people living with dementia (PLWD) in nursing homes. Reliable and valid measurements are needed to assess these disturbances. The aim of this systematic review was to identify, analyze and synthesize studies of sleep-related measurements to assess sleep disturbances in PLWD. The databases PubMed, CINAHL, and PsycINFO were systematically searched in 2019; the search was updated in March 2024. The inclusion criteria were as follows: participants with dementia or probable dementia in any care setting; and studies that reported at least one of the following aspects: (I) theoretical and conceptual frameworks, (II) user or patient involvement by type of users in measurement development, (III) feasibility and practicability of measurements, and (IV) results of psychometric analyses. The quality of the included studies was evaluated using the COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) criteria and the quality appraisal tool for studies of diagnostic reliability (QAREL) tool. A total of 5169 studies were identified; ultimately, 15 studies describing three self-administered measurements, three proxy-administered measurements and two technological measurements were included. No sleep-related measurement showed acceptable psychometric properties in any of the COSMIN domains. No measurement without adaptation can be recommended for PLWD in nursing homes. If existing measurements are used in clinical practice, the self-perspective of PLWD should be taken into account. If this is no longer fully possible, proxy-rating perspectives in combination could be an option. Future research on sleep-related measurements should be strictly based on international consensus-based psychometric quality criteria.

Adaptation and psychometric assessment of a sexual and reproductive empowerment scale in Arabic among refugee and non-refugee adolescent girls.

Sexual and reproductive empowerment (SRE) is an important determinant of women's and girls' health yet measuring it is complex due to cultural and domain-specific variations. This study describes the process of adapting an SRE scale consisting of four domains (self-efficacy; future orientation; social support; and safety) and testing its psychometric properties among Arabic speaking adolescent girls in Lebanon. An SRE scale developed in a Western context was adapted in four steps: (1) reviewing the scale and selecting culturally appropriate domains for translation to standard Arabic; (2) conducting cognitive interviews with 30 11-17-year-old adolescent girls in Lebanon; (3) administering the scale to 339 refugee adolescent girls who participated in an early marriage intervention; and (4) conducting confirmatory factor analysis (CFA) on the data to assess the scale's psychometric properties. The original model for the 13-item, four-domain adapted scale demonstrated poor fit in CFA. After iteratively removing two items, scale properties were improved, albeit were not optimal. The validity and reliability results for the self-efficacy domain were acceptable. Cognitive interview data revealed that Arab adolescent girls understood self-efficacy in relational terms, recognizing that autonomous decision-making is not necessarily favored but is influenced by parents and family. This study presents an effort to customize an SRE scale for use in studies on the health of adolescent girls in an Arab cultural context. Findings from cognitive interviews highlight the importance of taking into consideration relationality in adolescent sexual and reproductive decision-making. The self-efficacy domain in the adapted scale demonstrates acceptable psychometric properties and is recommended for use in health studies to capture SRE.

An initial validation of a new measure of client change in a correctional sample

ABSTRACT Ideally, when an individual enters the Criminal Justice System there is the goal and expectation that they will, over time and through intervention, change from the individual who perpetrated the crime(s) toward adopting a non-criminal identity. However, there are currently few measures of change with established validity for predicting post-program or post-release outcomes with correctional samples. The Client Change Scale [CCS; Serin & Lloyd, 2018] was developed to address this gap to provide an empirically grounded systematic measure of factors relevant for change. This study was the first to assess the psychometric properties of the CCS with post-release outcomes and to predict recidivism outcomes with a Canadian release cohort using archival data. The sample included 390 adult males under community supervision by the Correctional Service of Canada (CSC) between 2015 and 2017. Overall, the CCS reflected acceptable psychometric properties. Additionally, an exploratory factor analysis revealed that all 16 items of the CCS should be retained and provided evidence for separate but correlated consideration of internal and external change factors. These initial findings suggest the CCS has the potential to improve decision-making throughout an individual’s time in the criminal justice system by utilizing a person-centered approach in support of improving client success and subsequent public safety.

Tools for assessing the quality of life of hysterectomized women: A systematic review.

Since hysterectomy surgery is a major and invasive procedure, it can affect the quality of life of women in many ways. This study aimed to review and critique the psychometric properties of tools used to measure the quality of life of hysterectomized women. An advanced search was conducted in international (PubMed, Web of Science, Scopus, PsycINFO, Embase) as well as national databases (SID and Magiran) to retrieve articles published from 2000 to 2024, using keywords related to hysterectomy and quality of life. Then, the psychometric properties of the tools found in these articles were evaluated by COSMIN checklist. The psychometric properties of tools were analyzed using the COSMIN checklist. Among the 20 general and specific tools examined, content validity had not been evaluated in 15 tools, construct validity had not been evaluated in four tools, criterion validity had not been evaluated in eight tools, internal consistency had not been evaluated in five tools, responsiveness had not been evaluated in 16 tools, and interpretability had not been assessed in 18 tools, and measurement error had not been evaluated in any of the tools. The results showed that none of the evaluated tools have all the criteria of Cosmin's checklist. Of course, construct validity and reliability had been assessed in most of the tools. Meanwhile, there was no tool to measure the quality of life of hysterectomized women specifically. Therefore, it seems that developing a tool with acceptable psychometric properties is necessary to measure the quality of life of hysterectomized women specifically.

Translation, cross-cultural adaptation, and validation of the Italian version of the Parkinson's disease caregiver burden questionnaire (PDCB-I).

To translate and cross-culturally adapt the Parkinson's Disease Caregiver Burden questionnaire (PDBC) into Italian language and to evaluate the psychometric properties of the Italian version in terms of test-retest reliability, internal consistency, and construct validity. The PDBC-I was developed by forward-backward translation to establish correspondence with the original English latest version. Psychometric properties were estimated in a sample of primary caregivers of individuals with Parkinson's disease. Reliability testing included internal consistency (Cronbach's alpha), test-retest reliability (ICC), the standard error of measurement (SEM) and the minimal detectable change (MDC), also expressed as percentage (MDC%). Validity was estimated by comparing the PDBC -I to the Caregiver Burden Inventory (CBI) and the Short Form 36 (SF-36) (Pearson correlation coefficient). The questionnaire was administered to 65 caregivers, showing internal consistency of 0.934. ICC value was 0.811 (95% CI 0.708-0.880) for test-retest reliability, and the SEM and the MDC (MDC%) were 5.04 and 13.97 (38.21%), respectively. Low to moderate correlation with all other investigated scales (CBI: r=0.693; SF-36 physical score: r=-0.309; SF-36 mental score: r=-0.588; SF36 total score: -0.470) were found. Despite the PDCB-I holds acceptable psychometric properties to be used in clinical settings of Italian-speaking Countries as a measure of caregiver burden in caregivers of individuals with Parkinson Disease, the caregiver might require the support of a clinician to finalize the compilation of the questionnaire.

Lille Apathy Rating Scale-Patient Version in Stroke Survivors: Psychometric Properties and Diagnostic Accuracy

ObjectivesThis study evaluated the factorial structure, psychometric properties, and diagnostic accuracy of the Persian version of the Lille Apathy Rating Scale-Patient version (LARS-P) in stroke survivors. ParticipantsThis study comprised 105 stroke survivors and 41 healthy controls. Methods and SettingExploratory factor analysis was used to determine the factors of the LARS-P. The acceptability, reliability, and validity of the LARS-P were also assessed. Agreement between the LARS-P and the Lille Apathy Rating Scale-informed version (LARS-I) was evaluated using the Bland-Altman plot. The diagnostic accuracy of the LARS-P was determined by categorizing stroke survivors into apathetic and nonapathetic groups based on the “diagnostic criteria of apathy.” ResultsThe exploratory factor analysis showed 3 factors (action initiation and social life; novelty and motivation; and emotional and self-awareness), explaining 67.35% of the variance. Cronbach's alpha was 0.85 for between-items and 0.74 for between-subscales. Intra-class correlation coefficient (ICC)2,1 was >0.88 for test-retest and inter-rater reliability. The LARS-P showed moderate to strong correlations with the LARS-I and Neuropsychiatric Inventory-Apathy subscale (r = 0.70–0.82). In addition, the LARS-P had significant moderate correlations with 2 subscales of the Hospital Anxiety and Depression Scale, modified Rankin Scale, Barthel Index, and Lawton Instrumental Activities of Daily Living (r or ƿ = 0.47–0.63). There was a 96.19% agreement between LARS-P and LARS-I. The identified cutoff point (>17) for LARS-P exhibited 77.14% sensitivity and 90% specificity in diagnosing apathetic and nonapathetic stroke survivors. Conclusions and ImplicationsThe LARS-P exhibits acceptable psychometric properties in stroke survivors, presenting a promising instrument for assessing apathy through a multidimensional framework.

The Turkish version of the Skin Tear Knowledge Assessment Instrument (OASES): Validity and reliability study.

This study was conducted to adapt the Skin Tear Knowledge Assessment Instrument (OASES) into Turkish and to verify its validity and reliability. This study was conducted on 314 nurses in Türkiye between November 2023 and February 2024 to test the psychometric properties of OASES. The instrument consists of 20 items clustered into six domains. The cultural adaptation process was carried out according to the International Testing Commission guidelines: Turkish translation, expert panel, content validity, translation back to English, preliminary study and the final version of the instrument. To check the validity of the multiple-choice test, item difficulty and discriminating index were analysed. The reliability of the instrument was evaluated to the retest 14 days after the first test. Scale level content validity by 11 experts in wound care was 0,97 (I-CVI = 0.8-1.0). In the item analysed of the OASES, the item difficulty index was 0,51 (p-value = 0.34-0.76) and the discriminating index was 0.40 (D-value = 0.26-0.51). The 2-week test-retest intraclass correlation coefficient of the overall instrument was 0.90 (95% CI = 0.79-0.95). The Turkish version of OASES is a valid and reliable measurement instrument to evaluate nurses' knowledge levels regarding skin tears with acceptable psychometric properties. It can be applied in nursing education, research and practice to evaluate the knowledge of Turkish speaking nurses about skin tears.

Reliability, validity and minimal detectable change of the Chinese Version of the Assessment of Physical Activity in Frail Older People (APAFOP-C)

BackgroundPhysical activity (PA) is essential in mitigating frailty syndrome, and it is necessary to measure PA in older adults with frailty. Assessment of Physical Activity in Frail Older People (APAFOP) is a suitable patient-reported outcome measure (PROM) for assessing PA among older adults with frailty. This study aimed to determine the reliability, validity and minimal detectable change of the Chinese version of the APAFOP (APAFOP-C).MethodsThis cross-sectional validation study was designed to measure the reliability and criterion validity of the APAFOP-C with 124 frail community-residing older adults. APAFOP-C was completed twice within an interval of 7–17 days to determine test-retest reliability. The investigator triangulation method was used to investigate inter-rater reliability, and a pedometer was used as the reference measurement to assess the criterion validity. Reliability and criterion validity were assessed using the intraclass correlation coefficient (ICC2,1), Pearson correlation coefficient for normally distributed variables, Spearman correlation coefficient, Wilcoxon signed-rank test for skewed variables, and the minimal detectable change at 95% level of confidence (MDC95). Agreement assessment was conducted using Bland-Altman plots for inter-rater reliability and criterion validity. Kendall’s W test assessed absolute agreement among three raters in inter-rater reliability. The Mann-Whitney U test was used to evaluate whether any particular day was more representative of certain daily activities.ResultsTotal PA on any arbitrarily chosen day illustrates daily activity (Z= -0.84, p = 0.40). The APAFOP-C exhibited strong-to-very strong test-retest reliability (ICC2,1=0.73–0.97; Spearman ρ = 0.67–0.89), and the total PA score demonstrated MDC95 < 10%. Inter-rater reliability was also strong-to-very strong (ICC2,1=0.96–0.98; Spearman ρ = 0.88–1.00), and moderate criterion validity when compared with total PA score on pedometer readings (Spearman ρ = 0.61). Limits of agreement among different raters regarding the APAFOP-C and the pedometer were narrow.ConclusionThe APAFOP-C was found to have limited but acceptable psychometric properties for measuring PA among community-dwelling older adults with frailty in China. It was a feasible comparative PROM for assessing PA worldwide. Practitioners can develop individualized exercise programs for frail older adults and efficiently track changes in PA utilizing the APAFOP-C.
