The relation between subjective and objective measures of everyday life activities in persons with multiple sclerosis.

OBJECTIVES: To investigate the relation between subjective and objective performance-based measures of functional status in persons with multiple sclerosis (MS), and to compare their performance with healthy controls. DESIGN: A between-groups design, using a correlational approach to examine the relation between objective and subjective measures of functional capacity. SETTING: Outpatient rehabilitation research institution. PARTICIPANTS: Seventy-four subjects with clinically definite MS and 35 healthy controls. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: The Executive Function Performance Test (EFPT), Functional Assessment of Multiple Sclerosis (FAMS), and Functional Behavior Profile (FBP). RESULTS: MS participants reported more difficulties performing functional tasks than did the healthy controls. MS participants also performed significantly worse on the EFPT than healthy controls. However, all correlations between subjective and objective functional measures were nonsignificant. After controlling for depressive symptomatology, EFPT performance was significantly associated with FBP scores, but not FAMS scores. CONCLUSIONS: The lack of association between objective performance-based measures and subjective self-report measures of functional activities is a challenge to outcomes measurement and has implications for assessment of functional performance. Results are discussed in terms of the different dimensions that these tools are measuring and their respective strengths and limitations.

Reliability and validity of the multiple sclerosis quality of life inventory in older individuals.

PURPOSE: Despite the increasing number of older individuals with multiple sclerosis (MS), there is a paucity of research on this subpopulation. Health-related quality of life (HRQOL) has received extensive attention in MS; however samples tend to be young. The present study assesses the internal consistency reliability and construct validity of the MS Quality of Life Inventory (MSQLI), a widely employed measure of HRQOL, in older individuals. METHOD: Select subscales of the MSQLI and other measures of mental health and physical functioning were administered by telephone to 30 randomly selected older ( >or= 60) individuals and a gender-matched sample of younger ( < 60) individuals. Reliability estimates were calculated separately for each group. Construct (convergent) validity was assessed by examining the pattern of correlations between MSQLI subscales and measures of related constructs in the two groups. RESULTS: Reliability estimates were similar in the two groups. With few exceptions, the correlations measuring convergent validity were in the expected direction, and of considerable magnitude, in both groups. CONCLUSIONS: Results provide preliminary evidence that the MSQLI is a reliable and valid instrument for use with older individuals. The slightly different pattern of results observed in the validity analysis might be explained by an adjustment hypothesis. Future research on HRQOL in this subpopulation is encouraged.

Rethinking cognitive function in multiple sclerosis: a nursing perspective.

Cognitive impairment is a common problem in multiple sclerosis (MS); up to 65% of patients exhibit some neuropsychological dysfunction during the course of their disease. It is a major contributing factor to unemployment, accidents, impairment of daily functioning, and loss of social activity in those affected by MS. The areas of cognition typically impaired are memory, attention, information processing, executive functions, and visuospatial skills. Cognitive dysfunction is independent of disease duration and level of disability; cognitive decline may begin in the earliest stages of MS before patients become even mildly disabled. Structural brain imaging studies show a positive correlation between the extent of brain atrophy and cognitive dysfunction. Despite its prevalence in MS, cognitive dysfunction often goes undiagnosed or is misdiagnosed as depression, stress, stubbornness, lack of intelligence, or psychosis. Because nurses play such an important role in the care of patients with MS, they are in a position to identify patients with cognitive dysfunction, educate patients and their families on ways to cope with cognitive deficits, and counsel patients on available treatment options. Practical guidelines help nurses identify and care for cognitively impaired MS patients.
