Reliability and Validity of SymTrak, a Multi-Domain Tool for Monitoring Symptoms of Older Adults with Multiple Chronic Conditions.

ABSTRACT:

Background

A reliable and valid clinically practical multi-domain self-report and caregiver-report tool is needed for tracking actionable symptoms in primary care for elderly patients with multiple chronic conditions (MCCs).

Objective

Assess internal consistency reliability, test-retest reliability, construct validity, and sensitivity to change for SymTrak.

Design and participants

Among 600 (200 patient-caregiver dyads, 200 patients without an identified caregiver) participants, SymTrak was telephone interviewer-administered at baseline and 3-month follow-up, and at 24 h post-baseline for assessing test-retest reliability in a random subsample of 180 (60 dyads, 60 individual patients) participants.

Main measures

Demographic questions, SymTrak, Health Utility Index Mark 3 (HUI3).

Key results

Exploratory factor analysis indicated a single dominant dimension for SymTrak items for both patients and caregivers. Coefficient alpha and 24-h test-retest reliability, respectively, were high for the 23-item SymTrak total score for both patient-reported (0.85; 0.87) and caregiver-reported (0.86; 0.91) scores. Construct validity was supported by monotone decreasing relationships between the mean of SymTrak total scores across the poor-to-excellent categories of physical and emotional general health, and by high correlations with HUI3 overall utility score, even after adjusting for demographic covariates (standardized linear regression coefficient?=?-?0.84 for patients; -?0.70 for caregivers). Three-month change in the SymTrak total score was sensitive to detecting criterion standard 3-month reliable change categories (Improved, Stable, Declined) in HUI3-based health-related quality of life, especially for caregiver-reported scores.

Conclusions

SymTrak demonstrates good internal consistency and test-retest reliability, construct validity, and sensitivity to change over a 3-month period, supporting its use for monitoring symptoms for older adults with MCCs.

Project description:BackgroundPrevious questionnaires targeting older adults' sedentary time have underestimated total sedentary time, possibly by not including all relevant specific sedentary behaviors. The current study aimed to investigate the criterion validity and test-retest reliability of a new questionnaire assessing a comprehensive set of sedentary behaviors. Additionally, we examined whether the criterion validity of the questionnaire differed according to age, gender and educational level.MethodsA sample of home-dwelling Belgian older adults (>64 years, n?=?508) completed a newly-developed questionnaire assessing twelve specific sedentary behaviors and wore an accelerometer for seven consecutive days as criterion measure. A subsample (n?=?28) completed the questionnaire a second time to examine test-retest reliability. Data collection occurred between September 2010 and October 2012.ResultsCorrelational analyses examining self-reported total sitting time and accelerometer-derived sedentary time yielded a Spearman's ? of 0.30. Using the Bland-Altman regression procedure, self-reported total sitting time underestimated accelerometer-derived sedentary time by -82 minutes/day for a participant with an average level of sedentary time (539 minutes/day). Corresponding 95% limits of agreement were wide (-364, 200 minutes/day). Better, but still not ideal, validity findings were observed in the younger, male and tertiary-educated subgroups. Acceptable test-retest reliability (ICC?>?0.70) was found for total sitting time, TV viewing, computer use, and driving a car.ConclusionValidity for older adults' self-reported total sitting time against accelerometer-derived sedentary time was not strong, but comparable to previous studies. However, underestimation of total sedentary time was lower compared to previous studies, possibly explained by the inclusion of additional specific sedentary behaviors. Further research is needed to develop self-report tools and objective criterion measures that accurately measure engagement in (specific) sedentary behavior(s) among different subgroups of the older population.
