Evaluation of Internal Construct Validity and Unidimensionality of the Brachial Assessment Tool, A Patient-Reported Outcome Measure for Brachial Plexus Injury

IntroductionCrohn’s perianal fistulas are challenging for patients and clinicians. Many do not respond to available treatments and despite recommendations by a global consensus, there are currently no specific patient-derived quality of life tools to measure response to treatment. We present a new validated patient-reported outcome measure (PROM) for this complicated disease phenotype.MethodsA draft questionnaire was generated using unstructured qualitative patient interviews on the experience of living with Crohn’s perianal fistula, a nationwide multidisciplinary consensus exercise, a systematic review of outcomes assessing medical/surgical/combined treatment and a patient and public involvement day. Psychometric properties were assessed including construct validity (by comparison with the Hospital Anxiety and Depression Scale (HADS) and the UK Inflammatory Bowel Disease Questionnaire (UK-IBDQ)), and reliability and responsiveness was assessed by test–retest analysis.ResultsData from 211 patients contributed to development of a final 28-item questionnaire. The Crohn’s Anal Fistula Quality of Life (CAF-QoL) demonstrated good internal consistency (Cronbach’s alpha 0.88), excellent stability (intraclass correlation 0.98) and good responsiveness and construct validity, with positive correlation with the UK-IBDQ and HADS.ConclusionThe CAF-QoL scale is ready for use as a PROM in research and clinical practice. It complements objective clinical evaluation of fistula by capturing impact on the patient.

Background Prospects of a participation measure to be valid across cultures are debatable. Existing stroke outcome measures had been shown to have limited validity when used within Indian sociocultural contexts. Aim To develop and validate a patient-reported outcome measure of participation in daily activities appropriate for patients with stroke living in an Indian sociocultural context. Methods The scale was developed in two phases: scale development and psychometric testing. Items were derived from a conceptual framework of participation in daily activities of patients who had experienced stroke within an Indian context. The final version of the scale consisted of 25 items. A total of 377 patients diagnosed with stroke were recruited from two tertiary care hospitals and five physiotherapy outpatient rehabilitation centers in India. Psychometric testing of the scale included investigation of internal consistency, unidimensionality, construct validity (known group and convergent validity), and test–retest reliability. Results The scale items demonstrated good internal consistency (Cronbach’s alpha = .94). Confirmatory factor analysis results showed acceptable goodness of fit. The scale has shown good construct validity and test–retest reliability (intraclass correlation coefficient = 0.80). The scale differentiated patients with low and high disability severity (mean difference = 34, 95% CI = 27 to 39) and moderately associated with physical and instrumental activities of daily living ( r = 0.64, p < .001) and social participation domains of stroke impact scale ( r = 0.44, p < .001) and Barthel index ( r = 0.59, p < .001). Conclusion The Indian Stroke Scale has shown preliminary evidence of validity to support its use as a patient-reported outcome measure for evaluating poststroke participation in daily activities among patients with stroke in India.

AbstractOur aim was to validate a Finnish version of the Eating Assessment Tool (F-EAT-10) for clinical use and to test its reliability and validity in a multicenter nationwide study. Normative data were acquired from 180 non-dysphagic participants (median age 57.0 years, 62.2% female). Dysphagia patients (n = 117, median age 69.7 years, 53.0% female) referred to fiberoptic endoscopic evaluation of swallowing (FEES) completed F-EAT-10 before the examination and after 2 weeks. Patients underwent the 100-ml water swallow test (WST) and FEES was evaluated using the following three scales: the Yale Pharyngeal Residue Severity Rating Scale, Penetration-Aspiration Scale, and the Dysphagia Outcome Severity Scale. An operative cohort of 19 patients (median age 75.8 years, 57.9% female) underwent an endoscopic operation on Zenker’s diverticulum, tight cricopharyngeal muscle diagnosed in videofluorography, or both. Patients completed the F-EAT-10 preoperatively and 3 months postoperatively. The cut-off score for controls was < 3 (sensitivity 94.0%, specificity 96.1%) suggesting that ≥ 3 is abnormal. Re-questionnaires for test–retest reliability analysis were available from 92 FEES patients and 123 controls. The intraclass correlation coefficient was excellent for the total F-EAT-10 score (0.93, 95% confidence interval 0.91–0.95). Pearson correlation coefficients were strong (p < 0.001) for each of the questions and the total score. Internal consistency as assessed by Cronbach’s alpha was excellent (0.95). Some correlations between findings in FEES and 100-ml WST with F-EAT-10 were observed. The change in subjective symptoms of operative patients paralleled the change in F-EAT-10. F-EAT-10 is a reliable, valid, and symptom-specific patient-reported outcome measure for assessing dysphagia among Finnish speakers.
