Abstract Background: The Pittsburgh Fatigability Scale (PFS) was developed to capture fatigue and demand in a single tool, filling a gap that no validated questionnaire existed to measure perceived fatigability. Since fatigability is a more sensitive measure of a person’s susceptibility to fatigue, we validated the simplified-Chinese version of the PFS among Chinese community-dwelling older adults.Methods: The PFS was translated into the simplified-Chinese by the translation, retro-translation method. Internal consistency of the Physical subscale of the PFS was evaluated by Cronbach’s alpha. Convergent validity and discriminant validity were evaluated against physical performance measures (i.e., Short Physical Performance Battery & Timed Up and Go Test) and daily living performance (i.e., Barthel Index & Instrumental activity of daily living).Results: The simplified-Chinese version of PFS Physical scores showed strong internal consistency (Cronbach’s alpha=0.81). Higher PFS Physical scores were associated with worse physical performance, and daily living performance (|correlation coefficient| range: 0.36-0.56, p<.001). Age- and sex-adjusted PFS Physical scores had moderate to good overall discrimination for correctly classifying people by their physical performance and daily living performance (AUCs range 0.70-0.87, p<.001)Conclusions: The PFS simplified-Chinese version is a valid instrument to assess perceived physical fatigability in Chinese-speaking older adults with good convergent validity. Thus, the PFS, with low cost and greater feasibility, is a desired tool to measure fatigability in large population studies.

Abstract Background The Pittsburgh Fatigability Scale (PFS) was developed to capture fatigue and demand in a single tool, filling a gap that no validated questionnaire existed to measure perceived fatigability. Since fatigability is a more sensitive measure of a person’s susceptibility to fatigue, we validated the simplified-Chinese version of the PFS among Chinese community-dwelling older adults. Methods This cross-sectional study was conducted in an urban community in Beijing between November 2018 and July 2019. The PFS was translated into simplified-Chinese by the translation, retro-translation method. Internal consistency of the Physical subscale of the PFS was evaluated by Cronbach’s alpha. Convergent validity and discriminant validity were evaluated against physical performance measures (i.e., Short Physical Performance Battery & Timed Up and Go Test) and daily living performance (i.e., Barthel Index & Instrumental activity of daily living). Results Our study included 457 participants, including 182 men (39.8%) and 275 women (60.2%). The age range of the included participants was 61–96 years (mean = 84.8 years, SD = 5.8 years). The simplified-Chinese version of PFS Physical scores showed strong internal consistency (Cronbach’s alpha = 0.81). Higher PFS Physical scores were associated with worse physical performance, and daily living performance (|correlation coefficient| range: 0.36–0.56, p < .001). Age- and sex-adjusted PFS Physical scores had moderate to good overall discrimination for correctly classifying people by their physical performance and daily living performance (AUCs range 0.70–0.87, p < .001). Conclusions The PFS simplified-Chinese version is a valid instrument to assess perceived physical fatigability in Chinese-speaking older adults with good convergent validity. Thus, the PFS, with low cost and greater feasibility, is a desired tool to measure fatigability in large population studies.

Abstract Background Recently we validated the simplified-Chinese version of the Pittsburgh Fatigability Scale (PFS) Physical subscale. Next step is to validate the PFS Mental subscale in order to introduce a reliable measure of perceived mental fatigability among Chinese community-dwelling older adults. Methods This cross-sectional study was conducted in an urban community in Beijing. Internal consistency of the PFS Mental subscale was evaluated by Cronbach’s alpha. The participants were divided in half to evaluate the factor structure validity by exploratory factor analyses and confirmatory factor analysis. Convergent validity and discriminant validity were evaluated against cognitive function (assessed by MOCA) and global fatigue from FRAIL Scale. Results Our study included 370 participants (mean=83.8 years). The simplified-Chinese version of PFS Mental subscale showed strong internal consistency (total Cronbach’s alpha=0.82, each items Cronbach’s alpha ranged from 0.78 – 0.83). The results of exploratory factor analysis showed all 10 items loaded on two factors: moderate to high and low intensity activities, which explained 60.8% of the total variance. Confirmatory factor analysis showed fit indices: SRMSR = 0.090, RMSEA = 0.120, CFI = 0.89. PFS Mental scores demonstrated moderate concurrent and construct validity against cognitive function (r = -0.24, P&lt;.001). Additionally, the PFS Mental subscale had strong convergent validity, discriminating according to established cognitive impairment or FRAIL Scale fatigue testing cut points, with differences in PFS Mental scores ranging from 3.2 to 8.4 points. Conclusions The PFS Mental subscale simplified-Chinese version is a valid tool to assess perceived mental fatigability in Chinese-speaking older adults.

OBJECTIVE : To compare the reliability and convergent validity of instruments assessing quality of life in Brazilian older adults. METHODS : Cross-sectional study of 278 literate, community-dwelling older adults attending a municipal university for the elderly in Sao Carlos, SP, Southeastern Brazil between 2006 and 2008. The Brazilian versions of the SF-36 and WHOQOL-BREF instruments to assess quality of life were compared. Cronbach’s alpha coefficient was used to estimate reliability and Pearson’s correlation for comparison between the two scales. RESULTS : Most of participants were women (87.8%) with a mean age of 63.83±7.22 years. Both scales showed an acceptable internal consistency – WHOQOL-BREF Cronbach’s alpha was 0.832 and SF-36 was 0.868. There was a weak (r ≤ 0.6) correlation between the related fields in the two questionnaires. CONCLUSIONS : The SF-36 and WHOQOL-BREF are reliable instruments for clinical and research uses in Brazilian older women. To select one, researchers should consider which aspects of quality of life they aim to capture because of weak convergent validity signs. This study’s results indicate that WHOQOL-BREF may be more relevant to evaluate changes in the quality of life of older women because it prioritizes responses to the aging process and avoids focusing on impairment.

Abstract Background: Fear of falling (FOF) is a very pervasive problem among older adults. Consequently, many scales have been developed for its assessment. The Modified Fall Efficacy Scale (MFES) is one of the most popular FOF scales. The MFES was originally developed for use in developed countries, and thus may not be entirely suitable for use in developing countries due to cultural and environmental differences between the two country categories. This study was therefore designed to cross-culturally adapt and validate the MFES to Igbo culture and environment among community-dwelling older adults in Nnewi community using established guidelines.Methods : The original English version of the MFES (E-MFES) was translated, synthesized, back-translated, subjected to expert panel review, and pretested before producing the final Igbo version of the MFES (I-MFES). The E-MFES, the I-MFES and the Short Falls Efficacy International were randomly administered to consecutively recruited 109 consenting older adult residents of Nnewi (43.1% males; mean age=74.45±8.78 years). Obtained data was analysed using frequency counts, percentages, mean, standard deviation, Mann-Whitney U test, Spearman rank-order test, Cronbach’s alpha and principal component analysis at 0.05 level of significance.Results : All the 14 items on the E-MFES were retained on the I-MFES. There was no significant difference between the corresponding scores on the E-MFES and the I-MFES (p<0.05). The correlations between the corresponding scores on the I-MFES and the M-FES were all excellent (rho=0.97-1.00) indicating evidence of concurrent validity of the I-MFES. The correlation between the total scores on the I-MFES and the Short Falls Efficacy International was excellent (rho=9.3) indicating evidence of convergent validity. The Cronbach’s alpha value of the I-MFES is 0.97 showing evidence of excellent internal consistency.Conclusion : The I-MFES is a valid and reliable tool, and thus can be used as an outcome measure on Igbo older adults.

Abstract Background Many frequently used instruments fail to assess psychosocial functioning in patients with bipolar disorder. The Functioning Assessment Short Test (FAST) was developed in order to tackle this problem and to assess the main functioning problems experienced by patients with bipolar disorder. However, the original FAST is not fully applicable in older adults due to the domain of occupational functioning. The aim of our study was to validate an adapted version for Older adults (FAST-O) in a group of older adults with bipolar disorder (OABD). Methods 88 patients aged 50 years and over diagnosed with bipolar disorder were included. We adapted the items in the area of “work-related functioning” of the FAST into items assessing “societal functioning”. Several measurements were conducted in order to analyse the psychometric qualities of the FAST-O (confirmatory factor analysis for internal structure, Cronbach’s alpha for internal consistency, Spearman’s rho for concurrent validity, Mann–Whitney U test for discriminant validity). Results Mean age in the study sample was 65.3 (SD = 7.5) and 57.3% was female. The internal structure was most similar to the internal structure of the original FAST. The internal consistency was excellent (Cronbach’s alpha = .93). The concurrent validity when correlated with the Social and Occupational Functioning Assessment Scale was low, but significant. The FAST-O was also able to distinguish between euthymic and symptomatic OABD patients. Conclusions The FAST-O has strong psychometric qualities. Based on our results, we can conclude that the FAST-O is a short, efficient solution in order to replace global rating scales or extensive test batteries in order to assess daily functioning of older psychiatric patients in a valid and reliable manner.

IntroductionThe Oxford Happiness Inventory (OHI) 29-Item, each involving the selection of four options that are different for each item. Although there is an Arabic version, it is not identical to the original version in terms of the number of items and response.Objectivesto evaluate the psychometric properties of the Arabic adaptation OHI and its factorial structure in undergraduate sample.MethodsThe participants were 720 first year undergraduate Kuwaitis: 360 males mean age = 20.38 ± 1.60 and 360 females; mean age = 19.71 ± 1.39 (t = 5.87, P < 0.001). The Arabic version of OHI (Argyle, Martin, & Crossland) was administered to participants. The internal consistency reliability, factor structure, and convergent validity of the OHI with Life Orientation Test (LOT-R, Adult Hope Scale (AHS), Satisfaction With Life Scale (SWLS) were assessed as well as divergent validity of the OHI with Beck Depression Inventory-II (BDI-II)ResultsInternal consistency was satisfactory for the OHI (Cronbach's alpha = 0.87) for males and (Cronbach's alpha = 0.86) for females. The results revealed no significant gender differences on happiness (F = 1.77, P > 05). Principal component analyses (PCA) showed that a seven-component solution explains %50.50 of the total variance for males and 51.47% for females. The OHI positively correlates with the following variables: SWLS (r = .52), LOT-R (r = 0.56) AHS (r = .48) while the OHI correlates negatively with BDI-II (r = -54).ConclusionsFindings confirm that the OHI provides satisfactory validation, and thus it can be recommended as a measure of happiness among Arab samples.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Purpose This study aims at translating and adapting a common and widely used proxy rated cognitive screening tool – Informant Questionnaire on Cognitive Decline in the Elderly (IQCODE) into Hausa language and also to evaluate the instrument’s psychometric properties. Design/methodology/approach IQCODE was translated and adapted using a qualitative process involving experts and the adapted version was then evaluated against a gold standard (Diagnostic and Statistical Manual of Mental Disorder V criteria for neurocognitive disorders) with older adults subjects (N = 100), while its reliability (internal consistency) was also evaluated. Descriptive statistics of mean and frequencies, and inferential statistic of receiver operating curve analysis and Cronbach’s alpha coefficient were used for data analysis at an alpha level set at 0.05. Findings The Hausa IQCODE has a sensitivity value of 73.3%, specificity value of 71.8% and optimal cut-off values of between 3.2 and 3.3. For his adapted instrument the area under the Curve (AUC) curve is 0.79 (95% CI: 0.663–0.919; std. err: 0.066; P = 0.000), and Cronbach’s alpha value of 0.819 was obtained indicating that the adapted instrument has good internal consistency. Research limitations/implications The adapted IQCODE is a valid and reliable proxy based cognitive screening tool for the older adult Hausa speakers in Maiduguri. However, clinician and researcher might want to consider different optimal cut-off points when using this tool to screen or to monitor cognitive changes among older adults. Originality/value This research paper translated and adapted Hausa IQCODE into Hausa language. And it gives information on the validity and reliability of the adapted tool alongside with new optimal cut-off for cognitive screening by proxy among older adult patients in Nigeria.

Background: Maintaining dignity is important for successful aging, but there is lack of validated research instruments in the nursing literature to investigate dignity as perceived by the old people. Objective: This is a methodological study aiming to investigate the psychometric properties of the Greek version of Jacelon Attributed Dignity Scale as translated in the Greek language. Research design: A methodological approach consisting of translation, adaptation, and cross-cultural validation. A sample of 188 Greek-speaking old Cypriot persons drawn from the Hospital outpatient departments was asked to complete the Greek versions of Jacelon Attributed Dignity Scale and the Instrumental Activities of Daily Living. Data analyses included internal consistency reliability (Cronbach’s alpha coefficient), item analysis, and exploratory factor analysis using principal component method with orthogonal varimax rotation. Ethical considerations: The study protocol was approved by the National Bioethics committee according to the national legislation. Permission to use the research instrument was granted from the author. Information about the aim and the benefits of the study was included in the information letter. Findings: Cronbach’s alpha for Greek version of Jacelon Attributed Dignity Scale was 0.90. Four factors emerged explaining 65.28% of the total variance, and item to total correlation values ranged from 0.25 to 0.74 indicating high internal consistency and homogeneity. Mean item score in Instrumental Activities of Daily Living was 5.6 (standard deviation = 1.7) for men and 6.7 (standard deviation = 1.7) for women, and the correlations between demographics, Instrumental Activities of Daily Living, and the four factors of the Greek version of Jacelon Attributed Dignity Scale were low; also in multiple linear regression, the values of R2 are presented low. Discussion: Demographic characteristics and degree of functionality seem to be associated with some of the dimensions of dignity but with low correlations; therefore, they cannot predict attributed dignity. Conclusion: The Greek version of Jacelon Attributed Dignity Scale is a valid and reliable tool to measure attributed dignity in Greek-speaking older adults, but further testing of the psychometric properties and other potential factors that may affect the attributed dignity is needed.

Background: Infertility is a public health problem and can lead to depressive symptoms. In recent years, the WHO-five Well-being Index (WHO-5) has been used as a screening measure for depression, but study on psychometric properties in people with infertility is scarce. The objective of this study was to examine the reliability and validity of the Persian version of the WHO-5 in people with infertility. Methods: Overall, 539 infertile patients from a referral infertility center in Tehran, Iran in the period between May and Aug 2017, completed the WHO-5, along with other psychological measures: the Patient Health Questionnaire-9 (PHQ-9) and the Hospital Anxiety and Depression Scale (HADS). Construct validity and internal consistency of WHO-5 were evaluated using confirmatory factor analysis (CFA) and Cronbach’s alpha, respectively. Convergent validity was examined by relationship with PHQ-9 and HADS. Results: The prevalence of poor well-being was 44.3% and that of depression was 18.6%. CFA confirmed the unidimensional factor structure of the WHO-5. Internal consistency of the WHO-5 was good (Cronbach’s alpha=0.858). The WHO-5 significantly correlated with the PHQ-9 (r=-0.522), HADS-anxiety (r=-0.524) and HADS-depression (r=-0.630), confirming convergent validity. Conclusion: The WHO-5 is a short and easy to use questionnaire with satisfactory reliability and validity that appears suitable for use as a screening test for depressive symptom in infertile people. In addition, the prevalence of depression and poor well-being was very high in this population.

Introduction. Valid and feasible measures to properly assess the most impaired areas of functioning in various groups of patients with mental disorders would allow the development and evaluation of interventions designed to modify the specific environmental barriers that contribute to patients´ disability. Objective. This article seeks to evaluate the internal consistency and construct and convergent validity of the Spanish version of the World Health Organization’s Disability Assessment Schedule WHODAS 2.0, as well as its relationship with sociodemographic variables and symptomatic severity in Mexican patients with and without psychotic symptoms. Method. The WHODAS 2.0 and the Social and Occupational Functioning Assessment Scale SOFAS were administered to 153 patients with any of the following diagnoses: affective disorders, anxiety disorders, stress-related disorders, and psychotic disorders. Results. The WHODAS 2.0 showed high internal consistency in patients with psychotic symptoms (Cronbach’s alpha = .92) and without psychotic symptoms (Cronbach’s alpha = .89). Nevertheless, only in patients without psychotic symptoms, was a significant negative correlation between WHODAS (disability) and SOFAS (functioning) total scores observed, together with significant differences in WHODAS scores between those with mild and severe symptomatology. Discussion and conclusion. The WHODAS 2.0 is an adequate measure of disability in patients without psychotic symptoms. It could be used as a complementary measure of disability in those with psychotic symptoms. Further studies are required to determine other psychometric properties of the WHODAS 2.0, particularly those related to temporal stability and sensitivity to change.
