OBJECTIVE To develop a simple , valid , repeatable , and readily underst and able patient-oriented assessment measure for monitoring disease activity in children and adults with atopic eczema . DESIGN Qualitative semistructured patient interviews identified a list of symptoms of atopic eczema . These symptoms were quantitatively analyzed in a larger patient population to identify which symptoms were important to patients and amenable to monitoring as part of a scoring system . SETTING The outpatient Department of Dermatology at the Queen 's Medical Centre , University Hospital , Nottingham , Engl and , and 5 local general practice s. PATIENTS Four hundred thirty-five patients with atopic eczema . RESULTS Seven symptoms were incorporated into the final patient-oriented eczema measure using a simple 5-point scale of frequency of occurrence during the previous week , with a maximum total score of 28 . Validity testing against the Dermatology Life Quality Index , Children 's Dermatology Life Quality Index , and patients ' global severity assessment s showed good correlation ( r = 0.78 , r = 0.73 , and r = 0.81 , respectively ; P<.001 ) . Internal consistency was high ( Cronbach alpha = 0.88 ) , and test-retest reliability was good , with 95 % of scores falling within 2.6 points on repeat testing ( mean score difference , 0.04 ; SD , 1.32 ) . Individual variables in the measure demonstrated sensitivity to change during a 4-week in-clinic period and an 18-week r and omized controlled clinical trial . CONCLUSION The patient-oriented eczema measure is a practical self-assessed measurement tool for monitoring aspects of atopic eczema that are important to patients in routine clinical practice or in the clinical trial setting Objective To vali date the Eczema Area and Severity Index ( EASI ) by assessing its internal consistency , reliability and sensitivity to change and by correlating it to other efficacy parameters . Background Fatigue is a common symptom of chronic hepatitis C virus ( cHCV ) infection and a common side effect of interferon-based treatment for cHCV . This study provides confirmatory evidence of the reliability and validity of the Fatigue Severity Scale ( FSS ) to document fatigue in cHCV research and identifies values that indicate clinical ly important differences in FSS to aid in interpreting fatigue in cHCV clinical trials . Methods The study used data from two double-blind , r and omized , placebo-controlled , Phase IIb trials evaluating the efficacy and safety of simeprevir plus peginterferon-α/ribavirin  in treatment-naïve ( PILLAR , n = 386 ) and treatment-experienced patients ( ASPIRE , n = 462 ) with cHCV infection . Patients completed the FSS and EuroQoL 5 dimension question naire ( EQ-5D ) at baseline and at regular intervals throughout both trials . Reliability was assessed using Cronbach ’s coefficient α at Week 24 ( internal consistency reliability ) and intraclass correlation ( ICC ) between FSS at Weeks 12 and 24 in stable patients ( < 0.5 g/dL hemoglobin [ Hb ] change between Weeks 12/24 ) . Correlation with the EQ-5D visual analog scale ( VAS ) and “ Usual Activity ” domain score was used to assess concurrent validity . Clinical validity was evaluated using a case-control method to link spontaneously reported fatigue and anemia adverse events ( AEs ) during the study to FSS scores . Results FSS total scores demonstrated good reliability ( Cronbach ’s α : 0.95 , 0.96 ; ICC : 0.74 , 0.86 for PILLAR and ASPIRE , respectively ) and concurrent validity ( correlation with EQ-5D VAS : -0.63 , -0.66 ) with a monotonic relationship between the EQ-5D “ Usual Activities ” item response and FSS . Clinical validity was confirmed by a significant difference between cases and controls for fatigue AEs ( p < 0.05 ) ; however , anemia defined by AE or Hb abnormalities was only weakly related to FSS score . Analyses indicate that a change of 0.33–0.82 in mean FSS scores represents a meaningful improvement in fatigue , and a one-point change is a conservative indicator of an important change in individual FSS scores . Conclusion A difference of ≥0.7 in mean FSS scores can be considered a clinical ly important difference within groups over time or between groups . A one-point change or less in individual FSS scores indicates a clinical ly relevant change in fatigue Background : Insomnia is a prevalent health complaint that is often difficult to evaluate reliably . There is an important need for brief and valid assessment tools to assist practitioners in the clinical evaluation of insomnia complaints . Objective : This paper reports on the clinical validation of the  Insomnia Severity Index ( ISI )  as a brief screening measure of insomnia and as an outcome measure in treatment research . The psychometric properties ( internal consistency , concurrent validity , factor structure ) of the ISI were evaluated in two sample s of insomnia patients . Methods : The first study examined the internal consistency and concurrent validity of the ISI  in 145 patients evaluated for insomnia at a sleep disorders clinic . Data from the ISI were compared to those of a sleep diary measure . In the second study , the concurrent validity of the  ISI  was evaluated in a sample of 78 older patients who participated in a r and omized-controlled trial of behavioral and pharmacological therapies for insomnia . Change scores on the  ISI  over time were compared with those obtained from sleep diaries and polysomnography .  Comparisons were also made between ISI scores obtained from patients , significant others , and clinicians . Results : The results of Study 1 showed that the  ISI  has adequate internal consistency and is a reliable self-report measure to evaluate perceived sleep difficulties . The results from Study 2 also indicated that the ISI is a valid and sensitive measure to detect changes in perceived sleep difficulties with treatment . In addition , there is a close convergence between scores obtained from the ISI patient 's version and those from the clinician 's and significant other 's versions . Conclusions : The present findings indicate that the ISI is a reliable and valid instrument to quantify perceived insomnia severity . The ISI is likely to be a clinical ly useful tool as a screening device or as an outcome measure in insomnia treatment research BACKGROUND The evaluation of asthma symptoms is a core outcome measure in asthma clinical research . The Asthma Symptom Utility Index ( ASUI ) was developed to assess the frequency and severity of asthma symptoms . The psychometric properties of the ASUI are not well characterized , and a minimal important difference ( MID ) is not established . OBJECTIVES We assessed the reliability , validity , and responsiveness to change of the ASUI in a population of adult asthmatic patients . We also sought to determine the MID for the ASUI . METHODS Adult asthmatic patients ( n = 1648 ) from 2 previously completed multicenter r and omized trials were included .  Demographic information , spirometric results , ASUI scores , and other asthma question naire scores  were obtained at baseline and during follow-up visits . Participants also kept a daily asthma diary . RESULTS The internal consistency reliability of the ASUI was 0.74 ( Cronbach α ) . Test-retest reliability was 0.76 ( intraclass correlation ) . Construct validity was demonstrated by significant correlations between ASUI scores and Asthma Control Question naire scores ( Spearman correlation r = -0.79 ; 95 % CI , -0.85 to -0.75 ; P < .001 ) and Mini Asthma Quality of Life Question naire scores ( r = 0.59 ; 95 % CI , 0.51 - 0.61 ; P < .001 ) . Responsiveness to change was demonstrated , with significant differences between mean changes in ASUI scores across groups of participants differing by 10 % in percent predicted FEV(1 ) ( P < .001 ) and by 0.5 points in Asthma Control Question naire scores ( P < .001 ) . Anchor-based and statistical methods support an MID for the ASUI of 0.09 points . CONCLUSIONS The ASUI is reliable , valid , and responsive to changes in asthma control over time . The MID of the ASUI ( range of scores , 0 - 1 ) is 0.09 Objective We examine the reliability and validity of the Patient Health Question naire Anxiety and Depression Scale (PHQ-ADS)—which combines the nine-item Patient Health Question naire depression scale and seven-item Generalized Anxiety Disorder scale — as a composite measure of depression and anxiety . Methods Baseline data from 896 patients enrolled in two primary -care based trials of chronic pain and one oncology- practice –based trial of depression and pain were analyzed . The internal reliability , st and ard error of measurement , and convergent , construct , and factor structure validity , as well as sensitivity to change of the PHQ-ADS were examined . Results The PHQ-ADS demonstrated high internal reliability ( Cronbach & agr ; values of .8 to .9 ) in all three trials . PHQ-ADS scores can range from 0 to 48 ( with higher scores indicating more severe depression/anxiety ) , and the estimated st and ard error of measurement was approximately 3 to 4 points . The PHQ-ADS showed strong convergent ( most correlations , 0.7–0.8 range ) and construct ( most correlations , 0.4–0.6 range ) validity when examining its association with other mental health , quality of life , and disability measures . PHQ-ADS cutpoints of 10 , 20 , and 30 indicated mild , moderate , and severe levels of depression/anxiety , respectively . Bifactor analysis showed sufficient unidimensionality of the PHQ-ADS score . PHQ-ADS change scores at 3 months differentiated ( p < .0001 ) between individuals classified as worse , stable , or improved by a reference measure , providing preliminary evidence for sensitivity to change . Conclusions The PHQ-ADS may be a reliable and valid composite measure of depression and anxiety which , if vali date d in other population s , could be useful as a single measure for jointly assessing two of the most common psychological conditions in clinical practice and research . Trial Registration : Clinical trials.gov Identifier : NCT00926588 ( SCOPE ) ; NCT00386243 ( ESCAPE ) ; NCT00313573 ( INCPAD ) Background : Assessment of chemotherapy-induced peripheral neuropathy signs and symptoms has been hampered because of the lack of simple , reliable , and valid measures . Objective : The study objective was to examine the internal consistency and interrater reliability as well as the structural validity of a 5-component total neuropathy score-reduced ( TNSr ) variant and a chemotherapy-induced neuropathy-specific Neuropathic Pain Scale . Methods : One hundred seventeen out patients receiving taxanes or platinums  were assessed by a consistent nurse practitioner using the 2 instruments . Ten subjects participated in interrater reliability testing . Results : Mean scores and SDs for individual items were low . The strength item was deleted because of low interitem correlations and a floor effect . The reflex item was deleted because of low interitem correlations and its negative influence on Cronbach & agr;. Pin sensibility was deleted because of low factor loadings . The TNSr-short form and the chemotherapy-induced neuropathy-specific Neuropathic Pain Scale formed 2 distinct factors , providing evidence of structural validity . Cronbach & agr ; 's for the 2 instruments were .80 and .96 , respectively . The TNSr interrater reliability results suggested acceptable rater concordance , but minor revisions could further improve scoring precision . Conclusion : Clinimetric evidence supports the use of 2 new instruments when monitoring taxane- and platinum-related neuropathy and pain . Further instrument modifications are recommended , followed by additional testing in diverse population s. Implication s for Practice : With these new instruments , nurses can more easily incorporate prospect i ve neuropathy assessment into daily clinical practice . The outcome will be improved symptom awareness by oncology clinicians and patients , leading to fewer chemotherapy-induced peripheral neuropathy-related devastating effects on functionality and quality of life Background Implementation outcome measures are essential for monitoring and evaluating the success of implementation efforts . Yet , currently available measures lack conceptual clarity and have largely unknown reliability and validity . This study developed and psychometrically assessed three new measures : the Acceptability of Intervention Measure ( AIM ) , Intervention Appropriateness Measure ( IAM ) , and Feasibility of Intervention Measure ( FIM ) . Methods Thirty-six implementation scientists and 27 mental health professionals assigned 31 items to the constructs and rated their confidence in their assignments . The Wilcoxon one- sample signed rank test was used to assess substantive and discriminant content validity . Exploratory and confirmatory factor analysis ( EFA and CFA ) and Cronbach alphas were used to assess the validity of the conceptual model . Three hundred twenty-six mental health counselors read one of six r and omly assigned  vignettes depicting a therapist contemplating adopting an evidence -based practice ( EBP ) . Participants used 15 items to rate the therapist ’s perceptions of the acceptability , appropriateness , and feasibility of adopting the EBP . CFA and Cronbach alphas were used to refine the scales , assess structural validity , and assess reliability . Analysis of variance ( ANOVA ) was used to assess known-groups validity . Finally , half of the counselors were r and omly assigned to receive the same vignette and the other half the opposite vignette ; and all were asked to re-rate acceptability , appropriateness , and feasibility . Pearson correlation coefficients were used to assess test-retest reliability and linear regression to assess sensitivity to change . Results All but five items exhibited substantive and discriminant content validity . A trimmed CFA with five items per construct exhibited acceptable model fit ( CFI = 0.98 , RMSEA = 0.08 ) and high factor loadings ( 0.79 to 0.94 ) . The alphas for 5-item scales were between 0.87 and 0.89 . Scale refinement based on measure-specific CFAs and Cronbach alphas using vignette data produced 4-item scales ( α ’s from 0.85 to 0.91 ) . A three-factor CFA exhibited acceptable fit ( CFI = 0.96 , RMSEA = 0.08 ) and high factor loadings ( 0.75 to 0.89 ) , indicating structural validity . ANOVA showed significant main effects , indicating known-groups validity . Test-retest reliability coefficients ranged from 0.73 to 0.88 . Regression analysis indicated each measure was sensitive to change in both directions . Conclusions The AIM , IAM , and FIM demonstrate promising psychometric properties . Predictive validity assessment is planned BACKGROUND AND PURPOSE To be useful for clinical research , an outcome measure must be feasible to administer and have sound psychometric attributes , including reliability , validity , and sensitivity to change . This study characterizes the psychometric properties of the Stroke Impact Scale ( SIS ) Version 2.0 . METHODS Version 2.0 of the SIS is a self-report measure that includes 64 items and assesses 8 domains ( strength , h and function , ADL/IADL , mobility , communication , emotion , memory and thinking , and participation ) . Subjects with mild and moderate strokes completed the SIS at 1 month ( n=91 ) , at 3 months ( n=80 ) , and at 6 months after stroke ( n=69 ) . Twenty-five subjects had a replicate administration of the SIS 1 week after the 3-month or 6-month test . We evaluated internal consistency and test-retest reliability . The validity of the SIS domains was examined by comparing the SIS to existing stroke measures and by comparing differences in SIS scores across Rankin scale levels . The mixed model procedure was used to evaluate responsiveness of the SIS domain scores to change . RESULTS Each of the 8 domains met or approached the st and ard of 0.9 alpha-coefficient for comparing the same patients across time . The intraclass correlation coefficients for test-retest reliability of SIS domains ranged from 0.70 to 0.92 , except for the emotion domain ( 0.57 ) . When the domains were compared with established outcome measures , the correlations were moderate to strong ( 0.44 to 0.84 ) . The participation domain was most strongly associated with SF-36 social role function . SIS domain scores discriminated across 4 Rankin levels . SIS domains are responsive to change due to ongoing recovery . Responsiveness to change is affected by stroke severity and time since stroke . CONCLUSIONS This new , stroke-specific outcome measure is reliable , valid , and sensitive to change . We are optimistic about the utility of measure . More studies are required to evaluate the SIS in larger and more heterogeneous population s and to evaluate the feasibility and validity of proxy responses for the most severely impaired patients BACKGROUND Patient-reported outcomes ( PROs ) are essential for evaluating treatment effects on health-related quality of life and symptoms from the patient 's perspective . This study sought to evaluate the psychometric properties of the nine-item Functional Assessment of Cancer Therapy/National Comprehensive Cancer Network Colorectal Cancer Symptom Index ( FCSI-9 ) in a metastatic colorectal cancer ( mCRC ) population . METHODS The FCSI-9 and EQ-5D were administered every 2 - 4 weeks to mCRC subjects in a phase III clinical trial . Three hundred ninety-one mCRC subjects completed the question naires at baseline and at least one follow-up assessment . Internal consistency reliability , test-retest reliability , construct validity , known groups validity , responsiveness , and the minimum important difference ( MID ) of the FCSI-9 were evaluated . RESULTS The internal consistency and test-retest reliability of the FCSI-9 were acceptable ( 0.81 and 0.76 , respectively ) . Construct validity was supported based on moderate correlations with the EQ-5D . Known groups validity was evaluated by examining the FCSI-9 scores of subjects categorized by their Eastern Cooperative Oncology Group performance status ( PS ) score . Subjects with better PS scores reported significantly higher FCSI-9 scores than those with lower PS scores at both baseline and week 8 . Responsiveness , as measured by Guyatt 's statistic , was 0.77 from baseline to week 8 and 0.60 from week 4 to week 12 . Considering all data together , the MID of the FCSI-9 is estimated to be in the range of 1.5 - 3.0 points . CONCLUSION Results provide preliminary evidence of the reliability , validity , and responsiveness of the FCSI-9 Objective : To evaluate the reliability and responsiveness to change of an audit tool to assess adherence to evidence of effectiveness in the  speech and language therapy ( SLT ) management of poststroke dysphagia . Design : The tool was used to review SLT practice as part of a r and omized study of different education strategies . Medical records were audited before and after delivery of the trial intervention . Setting : Seventeen SLT departments in the north-west of Engl and participated in the study . Subjects : The assessment tool was used to assess the medical records of 753 patients before and 717 patients after delivery of the trial intervention across the 17 departments . A target of 10 records per department per month was sought , using systematic sampling with a r and om start . Analysis : Inter- and intra-rater reliability were explored , together with the tool 's internal consistency and responsiveness to change . Results : The assessment tool had high face validity , although internal consistency was low ( r a=0.37 ) . Composite scores on the tool were however responsive to differences between SLT departments . Both inter- and intra-rater reliability ranged from ‘ substantial ’ to ‘ near perfect ’ across all items . Conclusions : The audit tool has high face validity and measurement reliability . The use of a composite adherence score should , however , proceed with caution as internal consistency is low Background and Purpose — The National Institutes of Health Stroke Scale ( NIHSS ) is accepted widely for measuring acute stroke deficits in clinical trials , but it contains items that exhibit poor reliability or do not contribute meaningful information . To improve the scale for use in clinical research , we used formal clinimetric analyses to derive a modified version , the mNIHSS . We then sought to demonstrate the validity and reliability of the new mNIHSS . Methods — The mNIHSS was derived from our prior clinimetric studies of the NIHSS by deleting poorly reproducible or redundant items ( level of consciousness , face weakness , ataxia , dysarthria ) and collapsing the sensory item into 2 responses . Reliability of the mNIHSS was assessed with the certification data originally collected to assess the reliability of investigators in the National Institute of Neurological Disorders and Stroke ( NINDS ) rtPA ( recombinant tissue plasminogen activator ) Stroke Trial . Validity of the mNIHSS was assessed with the outcome results of the NINDS rtPA Stroke Trial . Results — Reliability was improved with the mNIHSS : the number of scale items with poor & kgr ; coefficients on either of the certification tapes decreased from 8 ( 20 % ) to 3 ( 14 % ) with the mNIHSS . With the use of factor analysis , the structure underlying the mNIHSS was found identical to the original scale . On serial use of the scale , goodness of fit coefficients were higher with the mNIHSS . With data from part I of the trial data , the proportion of patients who improved ≥4 points within 24 hours after treatment was statistically significantly increased by tPA ( odds ratio , 1.3 ; 95 % confidence limits , 1.0 , 1.8;P = 0.05 ) . Likewise , the odds ratio for complete/nearly complete resolution of stroke symptoms 3 months after treatment was 1.7 ( 95 % confidence limits , 1.2 , 2.6 ) with the mNIHSS . Other outcomes showed the same agreement when the mNIHSS was compared with the original scale . The mNIHSS showed good responsiveness , ie , was useful in differentiating patients likely to hemorrhage or have a good outcome after stroke . Conclusions — The mNIHSS appears to be identical clinimetrically to the original NIHSS when the same data are used for validation and reliability . Power appears to be greater with the mNIHSS with the use of 24-hour end points , suggesting the need for fewer patients in trials design ed to detect treatment effects comparable to rtPA . The mNIHSS contains fewer items and might be simpler to use in clinical research trials . Prospect i ve analysis of reliability and validity , with the use of an independently collected cohort , must be obtained before the mNIHSS is used in a research setting OBJECTIVE To test the reliability and validity of the 51-item Field Test Version of the National Eye Institute Visual Function Question naire ( NEI-VFQ ) across 5 common chronic eye conditions . DESIGN Prospect i ve observational cohort study of persons with 1 of 5 chronic eye diseases who were scheduled for nonurgent visits in ophthalmology practice s or had low vision from any cause , and a reference sample of persons without eye disease . SETTING Six university-based ophthalmology practice s and the National Eye Institute Clinical Center , Bethesda , Md. PATIENTS Eligible participants had to have 1 of the following eye conditions : age-related cataracts , age-related macular degeneration , diabetic retinopathy , primary open-angle glaucoma , cytomegalovirus retinitis , or low vision from any cause . Each of the 7 sites also enrolled persons in a reference sample . Reference sample participants had no evidence of underlying eye disease but were scheduled for either screening eye examinations or correction of refractive error . All eligible persons had to be aged 21 years or older , English speaking , and cognitively able to give informed consent and participate in a health status interview . MEASUREMENTS AND MAIN RESULTS To provide the data needed to assess the reliability and validity of the 51-item NEI-VFQ  , all subjects completed an interview that consisted of the 51-item NEI-VFQ , the Medical Outcomes Study 36-Item Short-Form Health Survey , and at least 1 measure of vision-targeted functional status . Estimates of internal consistency and test-retest reproducibility indicate that the 51-item NEI-VFQ is reliable . Tests of association with other scales and clinical variables support the construct validity of the survey . CONCLUSIONS In this cross-sectional study , the 51-item NEI-VFQ seems to be reliable and valid and should be a useful tool for group-level comparisons of vision-targeted , health-related quality of life in clinical research . Additionally , the psychometric properties of the NEI-VFQ were not influenced by the type or severity of the underlying eye disease , suggesting that the measure will provide reproducible and valid data when used across multiple eye conditions The  Patient Evaluation Measure ( PEM ) , The  Michigan H and Outcome Question naire ( MHQ )  and the Disabilities of the Arm , Shoulder and H and ( DASH ) score were assessed independent of their originators for reliability , construct and criterion validity and acceptability , using an ease of use question naire . These were administered in r and om order to 100 patients with different h and and wrist disorders and with different impairments of movement , pain , sensation and strength . The internal consistency of all three question naires was very high suggesting redundancy in the questions . All question naires were reproducible and valid for finger and wrist disorders , but less for nerve disorders . All had poor construct validity . The PEM was the easiest to underst and and complete , taking the least time . Correlation between the scales is high and conversion equations were calculated . All three are reliable and reproducible patient completed question naires , but the PEM is the easiest to use . The validity of all is suspected for nerve disorders Objective : To examine the reliability , validity and responsiveness of the generic Current Perceived Health 42 ( CPH42 ) Profile in Chinese patients with neck pain in Hong Kong . Design : A prospect i ve observational study . Setting : Physiotherapy outpatient departments . Subjects : Two sample s with 472 consecutive adult patients with neck pain from seven physiotherapy outpatient departments in Hong Kong . Methods : Subjects were requested to complete the CPH42 Profile , and their pain intensity was measured using the 11-point numerical rating scale ( NRS ) . They were observed and measured at the beginning of physiotherapy , at seven days , at week 3 and at week 6 after treatment began . Results : The CPH42 Profile had very good test – retest reliability and internal consistency ( intraclass correlation coefficient 0.91 , Cronbach 's alpha 0.90 ) . Validity was confirmed by a moderate correlation with the NRS at the beginning of treatment and week 6 ( rank correlation 0.41–0.53 ) . Moreover , a significant difference in scores was found between those who had sought medical consultation and /or had taken medication because of neck pain than those who did not . The responsiveness measured from the beginning of treatment to week 3 and week 6 ( st and ard response means of 0.33 and 0.36 ) was comparable to the respective changes in pain intensity . Conclusion : The CPH42 Profile has been shown to demonstrate good reliability and validity , and it is sensitive to changes in severity over time . It is suitable for use as an outcome measure for evaluation of patients with neck pain
CLINICAL IMPLICATION S Only SCORAD , EASI , and POEM currently perform adequately .
BACKGROUND Valid and reliable outcome measurements are a prerequisite for evidence -based practice .
The comparative validity and reliability of outcome measurements for assessing atopic eczema ( AE ) severity is unclear .
OBJECTIVE We sought to assess the validity , reliability , sensitivity to change , and ease of use of outcome measurements for AE .
We also sought to give recommendations on which outcomes to use in clinical research and for clinical monitoring .
