Reliability and validity of the functioning assessment short test for older adults with bipolar disorder (FAST-O)

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.

Breathlessness is a common and distressing symptom in older adults and an independent predictor of adverse outcomes. Yet, its multidimensional assessment has not been validated in older adults. We apply and validate the Multidimensional Dyspnoea Profile (MDP) in a sample of adults 75 years and older in Belgium.Breathlessness was rated with the MDP, modified Borg dyspnoea scale, numerical rating scale for intensity and unpleasantness both before and after exertion (the short battery of physical performance tests (SPPB)), as well as with the Medical Research Council dyspnoea scale. The Hospital Anxiety and Depression Scale (HADS) assessed the affective status. Factor structure was analysed with exploratory principal components analysis, internal consistency with Cronbach's alpha and concurrent validity with Spearman's correlation coefficients with other breathlessness scales, HADS and SPPB scores.In 96 participants (mean age: 85 years; 34% men) who rated breathlessness at both assessment points, exploratory principal components analysis identified two components: immediate perception (IP) and emotional reaction (ER) explaining most of MDP item variance (65.37% before and 71.32% after exertion). Internal consistency was moderate to high for MDP-IP (Cronbach's alpha=0.86 before and 0.89 after exertion) and MDP-ER (Cronbach's alpha= 0.89 before and 0.91 after exertion). The correlation patterns of MDP-IP and MDP-ER with other tests confirmed concurrent validity.The domain structure, reliability and concurrent validity of MDP for breathlessness before and after exertion were confirmed in a sample of adults 75 years and older, supporting its use and further research for the multidimensional profiling of breathlessness in older adults.

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.

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 BackgroundResponsiveness of Physicians (ROP) is defined as the social actions by physicians aimed at meeting the legitimate expectations of healthcare users. Even though patients’ expectations regarding ROP have increased during the COVID-19 pandemic, the psychometrically-validated ROP-Scale is difficult to apply in hospital settings. The goal of this study is to validate the existing ROP-Scale to measure the responsiveness of hospital physicians during the ongoing COVID-19 pandemic in Bangladesh.MethodsWe conducted a cross-sectional phone survey involving 213 COVID-19 hospital patients, randomly selected from the government database. We applied the Delphi method for content validity, exploratory factor analysis for construct validity, Cronbach's alpha and corrected item-total correlation for internal consistency reliability, and Pearson's correlation between the scale and overall patient satisfaction for concurrent validity.ResultsAfter removing survey items based on data sufficiency, collinearity, factor loading, and internal consistency, the final version of the COVID-19 ROP-Scale consisted of 12 items, grouped under Courteousness, Informativeness, Financial Sensitivity, and Treatment Provision Sensitivity domains. The scale was internally consistent, with a Cronbach's alpha coefficient of 0.83. The corrected item-total correlation ranged between 0.37 and 0.72. Concurrent validity was ascertained by the high correlation (0.78) between patient satisfaction and the COVID-19 ROP-Scale. Based on the median domain score, the highest- and the lowest-scoring responsiveness domain was 'Courteousness' (7.45) and 'Financial sensitivity' (1.85), respectively, whereas the highest- and the lowest-scoring item was 'Respect during the consultation' (8.16), and 'Providing treatment cost estimate before starting treatment' (1.78).ConclusionsThe 12-item COVID-19 ROP-Scale was demonstrated to be feasible, valid, and internally consistent. Therefore, at a time when many countries, including Bangladesh, have started experiencing new pandemic waves, its application can help amend past mistakes in health service provision and improve care for the hospitalised COVID-19 patients or other patients suffering from similar conditions. This study can contribute to the national decision-making regarding hospital care, open up further avenues in the health policy and system research, and eventually improve the quality of care provided to Bangladeshi patients seeking hospital services. Moreover, findings yielded by this study can be incorporated into doctors' medical education and in-service training.

IntroductionBreathlessness is a cardinal symptom in cardiorespiratory disease. An instrument for measuring different aspects of breathlessness was recently developed, the Multidimensional Dyspnea Profile (MDP). This study aimed to validate the MDP in terms of the underlying factor structure, internal consistency, test–retest reliability and concurrent validity in Swedish outpatients with cardiorespiratory disease.MethodsOutpatients with stable cardiorespiratory disease and breathlessness in daily life were recruited. Factor structure of MDP was analysed using confirmatory factor analysis; internal consistency was analysed using Cronbach’s alpha; and test–retest reliability was analysed using intraclass correlation coefficients (ICCs) for patients with unchanged breathlessness between assessments (baseline, after 30–90 min and 2 weeks). Concurrent validity was evaluated using correlations with validated scales of breathlessness, anxiety, depression and health-related quality of life.ResultsIn total, 182 outpatients with cardiorespiratory disease and breathlessness in daily life were included; 53.3% were women; main diagnoses were chronic obstructive pulmonary disease (24.7%), asthma (21.4%), heart failure (19.2%) and idiopathic pulmonary fibrosis (18.7%). The MDP total, immediate perception and emotional response scores, and individual item scores showed expected factor structure and acceptable measurement properties: internal consistency (Cronbach’s alpha, range 0.80–0.93); test–retest reliability at 30–90 min and 2 weeks (ICC, range 0.67–0.91); and concurrent validity. There was no evidence of a learning effect. Findings were similar between diagnoses.DiscussionMDP is a valid instrument for multidimensional measurement of breathlessness in Swedish outpatients across cardiorespiratory diseases.

Background: Bipolar disorder (BD) is often misdiagnosed as major depressive disorder (MDD) in older patients. This study examined the psychometric properties of the 33-item Hypomania Checklist (HCL-33) and its accuracy to differentiate BD from MDD among older adults. Method: A total of 215 depressed older patients were recruited; 107 were diagnosed with BD (71 with BD-type I and 36 with BD-type II) and 108 with MDD. Principal components analysis (PCA) was used to explore the factor structure of the HCL-33. Cronbach’s alpha was calculated to test the internal consistency. Intra-class correlation coefficient (ICC) was used to measure test-retest reliability. The receiver operating characteristic (ROC) analysis was used to generate the optimal cut-off value to differentiate between BD and MDD. Results: Two factors were identified in the PCA analysis accounting for 33.9% of the total variance. The Cronbach’s alpha value for the HCL-33 was 0.912, with 0.922 for factor I and 0.664 for factor II. The test-retest reliability was excellent (ICC: 0.891). The optimal cut-off of the HCL-33 total score for discriminating between MDD and BD was 14, with a sensitivity of 88.8% and specificity of 82.4%. Conclusion: The HCL-33 had satisfactory reliability and validity and could be used to distinguish BD from MDD in older adults.

IntroductionBreathlessness is the cardinal symptom in both cardiac and respiratory diseases, and includes multiple dimensions. The multidimensional instrument Dyspnoea-12 has been developed to assess both physical and affective components of breathlessness. This study aimed to perform a clinical validation of the Swedish version of Dyspnoea-12 in outpatients with cardiorespiratory disease.MethodsStable outpatients with cardiorespiratory disease and self-reported breathlessness in daily life were recruited from five Swedish centres. Assessments of Dyspnoea-12 were performed at baseline, after 30–90 min and after 2 weeks. Factor structure was tested using confirmatory factor analysis and internal consistency using Cronbach’s alpha. Test–retest reliability was analysed using intraclass correlation coefficients (ICCs). Concurrent validity at baseline was evaluated by examining correlations with lung function and several instruments for the assessment of symptoms and health status.ResultsIn total, 182 patients were included: with the mean age of 69 years and 53% women. The main causes of breathlessness were chronic obstructive pulmonary disease (COPD; 25%), asthma (21%), heart failure (19%) and idiopathic pulmonary fibrosis (19%). Factor analysis confirmed the expected underlying two-component structure with two subdomains. The Dyspnoea-12 total score, physical subdomain score and affective subdomain scores showed high internal consistency (Cronbach’s alpha 0.94, 0.84 and 0.80, respectively) and acceptable reliability after 2 weeks (ICC total scores 0.81, 0.79 and 0.73). Dyspnoea-12 showed concurrent validity with the instruments modified Medical Research Council scale, COPD Assessment Test, European Quality of Life-Five Dimensions-Five levels, the Functional Assessment of Chronic Illness Therapy-Fatigue, the Hospital Anxiety and Depression Scale, and with forced expiratory volume in 1 s in percentage of predicted value. The results were consistent across different cardiorespiratory conditions.ConclusionThe Dyspnoea-12 is a valid instrument for multidimensional assessment of breathlessness in Swedish patients with cardiorespiratory diseases.
