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.

Project description:BACKGROUND:With the growing number of young-older adults (baby-boomers), there is an increasing demand for assessment tools specific for this population, which are able to detect subtle balance and mobility deficits. Various balance and mobility tests already exist, but suffer from ceiling effects in higher functioning older adults. A reliable and valid challenging balance and mobility test is critical to determine a young-older adult's balance and mobility performance and to timely initiate preventive interventions. The aim was to evaluate the concurrent validity, inter- and intrarater reliability, internal consistency, and ceiling effects of a challenging balance and mobility scale, the Community Balance and Mobility Scale (CBM), in young-older adults aged 60 to 70 years. METHODS:Fifty-one participants aged 66.4?±?2.7 years (range, 60-70 years) were assessed with the CBM. The Fullerton Advanced Balance scale (FAB), 3-Meter Tandem Walk (3MTW), 8-level balance scale, Timed-Up-and-Go (TUG), and 7-m habitual gait speed were used to estimate concurrent validity, examined by Spearman correlation coefficient (?). Inter- and intrarater reliability were calculated as Intra-class-correlations (ICC), and internal consistency by Cronbach alpha and item-total correlations (?). Ceiling effects were determined by obtaining the percentage of participants reaching the highest possible score. RESULTS:The CBM significantly correlated with the FAB (??=?0.75; p?<?.001), 3MTW errors (??=?-?0.61; p?<?.001), 3MTW time (??=?-?0.35; p?=?.05), the 8-level balance scale (??=?0.35; p?<?.05), the TUG (??=?-?0.42; p?<?.01), and 7-m habitual gait speed (??=?0.46, p?<?.001). Inter- (ICC2,k?=?0.97), intrarater reliability (ICC3,k?=?1.00) were excellent, and internal consistency (??=?0.88; ??=?0.28-0.81) was good to satisfactory. The CBM did not show ceiling effects in contrast to other scales. CONCLUSIONS:Concurrent validity of the CBM was good when compared to the FAB and moderate to good when compared to other measures of balance and mobility. Based on this study, the CBM can be recommended to measure balance and mobility performance in the specific population of young-older adults. TRIAL REGISTRATION:Trial number: ISRCTN37750605 .
