Norwegian version of the Edinburgh cognitive and behavioural ALS screen: Construct validity, internal consistency, inter-rater, and test-retest reliability.

BACKGROUND: Research collaboration highlight a need for validated tests in other languages than English. Translation and culture adjustments may threaten essential features of the original instrument. OBJECTIVE: To assess the internal consistency, inter-rater and test-retest reliability, and construct validity of the Norwegian version of the Edinburgh Cognitive and Behavioural Amyotrophic Lateral Sclerosis (ALS) Screen (ECAS-N). METHODS: Performance of 71 subjects with ALS, 85 healthy controls (HC) and 6 controls with Alzheimer's disease (AD) were assessed with the ECAS-N. Test-retest interval was four months. Internal consistency was evaluated using Cronbach's alpha; reliability was assessed using intraclass correlation coefficient (ICC), Cohen's kappa, and Bland Altman plot. Five hypothesis, including the Montreal Cognitive Assessment (MoCA) screen, was evaluated for construct validity. RESULTS: ECAS-N total score produced a Cronbach's alpha of 0.65, had excellent inter-rater reliability (ICC = 0.99) and acceptable test-retest reliability (ICC = 0.73). Construct validity analysis suggested valid use of the ECAS-N to distinguish people with ALS-specific cognitive impairment from HC (p = 0.001) and those with AD (p = 0.002). The MoCA and ECAS-N were moderately correlated (r = 0.53). CONCLUSION: The ECAS-N has potential to be used by different testers in clinical practice and research to screen patients with ALS who speak Norwegian and for documenting cognitive impairment over time.

The Assistive Device Situation for ALS Patients in Norway.

AIMS: There are limited analytical descriptions of the assistive device situation in Norway for patients with ALS and other motor neuron diseases. This study is aimed at investigating how patients, caregivers, and healthcare professionals (occupational therapists and physiotherapists) experience the assistive device situation. METHODS: Twenty-four interviews were conducted with patients with motor neuron disease, caregivers, and healthcare professionals involved in procurement and adaptation of assistive devices. Systematic text condensation was used to analyse the interviews. RESULTS: The majority of patients and caregivers had positive experiences of follow-up by the specialist healthcare service. Several found follow-up by the primary health service to be deficient owing to inadequate expertise, continuity, and resources. Healthcare professionals reported having a proactive approach to identifying needs for assistive devices, but for various reasons, application processes were often delayed. Several patients indicated a reluctance to use assistive devices and were ambivalent regarding proactivity. The availability of assistive devices for some functional impairments was described as inadequate. Some patients felt there was too little focus on sexuality in the follow-up. The respondents had a number of suggestions for improving the assistive device situation. CONCLUSIONS: Multidisciplinary ALS teams are found to ensure follow-up expertise and continuity. Healthcare professionals wish to take a proactive approach to assistive devices, but a number of bureaucratic obstacles occur. The study findings are preliminary and should be validated through a prospective national quality registry for motor neuron diseases.
