The telehealth satisfaction scale: reliability, validity, and satisfaction with telehealth in a rural memory clinic population.

INTRODUCTION: Patient satisfaction is a key aspect of quality of care and can inform continuous quality improvement. Of the few studies that have reported on patient satisfaction with telehealth in programs aimed at individuals with memory problems, none has reported on the psychometric properties of the user satisfaction scales used. MATERIALS AND METHODS: We evaluated the construct validity and internal consistency reliability of the Telehealth Satisfaction Scale (TeSS), a 10-item scale adapted for use in a rural and remote memory clinic (RRMC). The RRMC is a one-stop interprofessional clinic for rural and remote seniors with suspected dementia, located in a tertiary-care hospital. Telehealth videoconferencing is used for preclinic assessment and for follow-up. Patients and caregivers completed the TeSS after each telehealth appointment. With data from 223 patients, exploratory factor analysis was conducted using the principal components analysis extraction method. RESULTS: The eigenvalue for the first factor (5.2) was greater than 1 and much larger than the second eigenvalue (0.92), supporting a one-factor solution that was confirmed by the scree plot. The total variance explained by factor 1 was 52.1%. Factor loadings (range, 0.54-0.84) were above recommended cutoffs. The TeSS items demonstrated high internal consistency reliability (Cronbach's alpha=0.90). Satisfaction scores on the TeSS items ranged from 3.43 to 3.72 on a 4-point Likert scale, indicating high satisfaction with telehealth. CONCLUSIONS: The study findings demonstrate high user satisfaction with telehealth in a rural memory clinic and the sound psychometric properties of the TeSS in this population.

Quality of life in early dementia: Comparison of rural patient and caregiver ratings at baseline and one year.

This study examined change in patient and caregiver ratings of patient quality of life (QOL) over one year in individuals with dementia living in rural and remote settings. The sample was selected from non-institutionalized patients who were assessed at an interprofessional memory clinic. Measures of QOL, cognitive function, depression, and functional ability were completed by the patient. Caregivers completed measures of patient QOL and behavior, and their own burden and distress. At baseline (clinic day) 119 patients and family caregivers were assessed. Thirty-two families had complete data at clinic day and one-year follow-up. There was no significant change in either patient or caregiver-rated QOL over one year. Significant predictors of patient self-rated QOL were patient symptoms of depressed mood and functional ability at clinic day, and symptoms of depressed mood and clinic day QOL at one year. Significant predictors of caregiver-rated patient QOL were caregiver burden, patient functional ability, and symptom severity at clinic day, and caregiver burden at one year. Patient and caregiver ratings of patient QOL were moderately associated, but neither patients nor their caregivers reported a significant change in patient QOL. Changes in QOL over time remain a unique individual experience that cannot be entirely predicted by analytical models.
