“…The instrument demonstrates excellent accessibility, reliability, validity, and good responsiveness to change in PWA (Hilari et al, 2003) and people with stroke with or without aphasia (SAQOL-39g, Hilari et al, 2009). It has been adapted for several languages, including in Europe: Italian (Posteraro, et al, 2004), Greek (Kartsona & Hilari, 2007;Efstratiadou et al, 2012), Spanish (LataCaneda et al, 2009), Norwegian (Berg, Haaland-Johansen, & Hilari, 2010), and Flemish (Manders, Dammenkens, Leemans, & Michiels, 2010). Furthermore, the SAQOL-39 is currently used in large-scale evaluations of the effectiveness of aphasia therapy in Germany (Baumgaertner et al, 2013) and Australia (Godecke et al, 2014).…”

“…Studies in samples that were not defined specifically by cerebrovascular disease were excluded (e.g. heart failure and diabetes) [4,5,6,7,8,9]; 2 studies used the MoCA to assess the convergent [10] and discriminant [11] validity of other tests in stroke patients; since they reported no evidence relevant to the validity of the MoCA for assessment of cognitive impairment, these papers were excluded. Reference lists of included papers were examined to identify additional papers for inclusion.…”

Cognitive impairment is common among patients with stroke or other cerebrovascular disease and influences long-term outcome, including occupational functioning. Recognition and monitoring of mild cognitive impairment is thus essential to good patient care. The Montreal Cognitive Assessment (MoCA) has been suggested as a brief screening test of vascular cognitive impairment. This paper presents a critical review of the research literature evaluating the validity and utility of this test with the aim of informing future clinical and research practice. A total of 30 papers employing the MoCA in the context of cerebrovascular disease were identified. Reporting of the methods and results of such studies tended to fall short of the established reporting guidelines. Under-specification of the exclusion criteria applied and their impact make it difficult to assess the potential impact of sampling bias and loss to follow-up. Nevertheless, content validity evidence suggests that the MoCA covers most of the domains that represent cognitive impairment in cerebrovascular disease, with mixed evidence for its preferential sensitivity to the type of cognitive impairment encountered in the context of vascular disease. Evidence clearly supports the need to establish norms and cut-offs for the MoCA that are culturally appropriate and that are matched to the range of cognitive impairment that is present in the population being assessed. Recent modifications of the MoCA have been developed for assessing patients with visual impairment or restricted mobility, which may reduce the impact of ‘untestability' on cognitive screening in the clinic or research context. The MoCA correlates well with other measures of cognitive and functional abilities in patients with cerebrovascular disease, and may also predict future response to rehabilitation and long-term occupational outcome. Further research is needed to provide evidence for the validity of the MoCA in longitudinal studies. However, it compares favourably to the Mini Mental State Examination as a screening test that is sensitive to the milder forms of cognitive impairment that often accompany cerebrovascular disease.

“…This study aimed to assess proxy-self-report agreement on the Greek version of the SAQOL-39g (Kartsona & Hilari, 2007). The Greek SAQOL-39g has strong psychometric properties, with excellent acceptability (minimal missing data; no floor/ceiling effects), test-retest reliability (ICC = 0.96 scale, 0.83 -0.99 domains), internal consistency (Cronbach's alpha 0.96 scale, 0.92 -0.96 domains), and convergent (r = 0.53 -0.80 scale; 0.54 -0.89 domains) and discriminant validity (r = 0.52 scale; 0.04 -0.48 domains) (Efstratiadou, Chelas, Ignatiou, Christaki & Hilari, 2012). We expected to replicate the findings of previous research.…”

Health related quality of life (HRQL) measures are increasingly used to evaluate stroke interventions. People with severe aphasia after stroke may be unable to self-report on such measures, necessitating the use of proxy respondents. This study explored the level of agreement between people with aphasia and their proxies on the Greek Stroke and Aphasia Quality of Life Scale-39 generic version (SAQOL-39g) and whether this agreement was influenced by proxy levels of depression and carer strain. Methods: Participants were people with aphasia (PWA) who were over six months post-stroke and medically stable. Proxies were nominated by the PWA and had to see them at least twice a week. PWA completed the Frenchay Aphasia Screening Test and the Greek SAQOL-39g. Proxies completed the Greek SAQOL-39g proxy version, the General Health Questionnaire-12 and the Caregiver Strain Index. Results: 23 pairs of people with aphasia and their proxies took part. Proxies rated people with aphasia as more severely affected than they rated themselves. The difference was significant for the overall scale and the physical and communication domains (p < 0.05); yet the bias introduced by these differences was small to moderate, with effect sizes ranging from 0.15 to 0.47. The strength of the agreement between people with aphasia and proxies was excellent for the overall scale and all three domains (ICC = 0.79-0.97). The level of agreement was not associated with carer strain or emotional distress. We conclude that clinicians and researchers can use proxy ratings to evaluate the quality of life of people with severe aphasia but need to be aware of trends in proxy reporting and take these into account when interpreting data.
