“…A limitation of this work is that the MrOS sample is restricted to primarily white men, most of whom have higher educational attainment and lower prevalence (24%) of greater perceived mental fatigability than other comparable cohorts (Cohen et al, 2021; Simonsick et al, 2018). We also excluded individuals without complete data (more likely to be Black or Asian, older, lower cognitive function scores, and reported worse health, all p <0.05).…”

“…Each model began with one personality trait of interest. Age was included in all models as it is known to be correlated with perceived mental fatigability (Wasson et al, 2019; Cohen et al, 2021). Covariates were entered into the four models for each personality trait one group at a time: first demographics, then psychological/behavioral factors, and last health-related conditions.…”

Objective Examine the association between personality measures and perceived mental fatigability. Methods We performed a cross-sectional analysis in N=1670 men, age 84.3±4.1 years. Multivariable linear regression models were used to examine the covariate adjusted association between personality measures (conscientiousness, optimism, goal reengagement, and goal disengagement) and perceived mental fatigability (measured with the validated 10-item Pittsburgh Fatigability Scale, PFS). Results One standard deviation lower conscientiousness (β=−0.91, p<.0001) and optimism (β=−0.63, p<.0001), and higher goal reengagement (β=0.51, p=.01) scores were independently associated with higher PFS Mental scores adjusted for age, cognitive function, self-reported health status, depressive symptoms, sleep disturbance, physical activity, and goal disengagement. Discussion Lower conscientiousness, optimism, and higher goal reengagement were linked with more severe perceived mental fatigability in older men. Personality traits may potentially contribute to early risk assessment for fatigability in later life. Future work should be longitudinal in nature and include personality assessments to confirm the temporality of the relationships observed.

“…In a recent study that reported validation results for the Dutch PFS for older adults, the Dutch version had good content validity and construct validity, but confirmatory factor analysis of the original factor structure showed poor model fit (with SRMR and CFI values of 0.29 and 0.75, respectively) [27]. In another recent study involving people with and without chronic disease, convergent validity and discriminant validity were supported for the PFS [22]. Our findings partially support the validity of the K-PFS, but future studies should investigate its construct, discriminant, and criterion validity.…”

“…Our study showed that 71.1% of women had greater physical fatigability (M = 20.47, K-PFS Physical score ≥ 15) and that 52.6% had greater mental fatigability (M = 14.35, K-PFS Mental score ≥ 13). A previous study involving two generations of family members enriched for exceptional longevity and their spouses (N = 2355, M:73.7 years) using the same PFS instrument reported that physical fatigability prevalence was higher in older aged groups (e.g., 60-60 years: 28%, 90-108 years: 89.5%) [28], and another study involving 2,361 older adults (M:73.6 years) also showed that mental fatigability was strikingly greater with age (e.g., 60-60 years: 14.5%, 90-108 years: 67.2%) [22]. Compared to the previous two studies, we found it noteworthy that even after an average of more than 7 years, women with breast cancer (M:55.4 years) still experienced greater fatigability equivalent to very old adults.…”

“…Each item is rated on a scale ranging from 0 (no fatigue) to 5 (extreme fatigue), and possible total scores range from 0 to 50; higher scores indicate greater physical and mental fatigability. The PFS Physical score of 15 or above indicated a greater level of physical fatigability, and the PFS Mental score of 13 or above was identified as indicating a greater level of mental fatigability [20][21][22]. In a previous study, the instrument was found to have high concurrent and convergent validity in relation to performance fatigability, mobility, physical function, and fitness, and its internal consistency was good, with a Cronbach's alpha for fatigability of 0.88 [16].…”

Background Fatigability has recently emerged in oncology as a concept that anchors patients’ perceptions of fatigue to defined activities of specified duration and intensity. This study aimed to examine the psychometric properties of the Korean version of the Pittsburgh Fatigability Scale (K-PFS) for women with breast cancer. Methods This cross-sectional study involved 196 women with breast cancer recruited from a tertiary hospital in Seoul, Korea. Reliability was evaluated using Cronbach’s alpha, and confirmatory factor analysis was conducted to examine the factor structure of the K-PFS. Four goodness-of-fit values were evaluated: (1) the comparative fit index (CFI), (2) the Tucker–Lewis index (TLI), (3) the root mean square error of approximation (RMSEA), and (4) the standardized root mean square residual (SRMR). Results Of the 196 survivors, 71.1% had greater physical fatigability (K-PFS Physical score ≥ 15) and 52.6% had greater mental fatigability (K-PFS Mental score ≥ 13). The Cronbach’s alpha coefficient for the total K-PFS scale was 0.926, and the coefficients for the physical and mental fatigability domains were 0.870 and 0.864, respectively. In the confirmatory factor analysis for physical fatigability, the SRMR value (0.076) supported goodness of fit, but other model fit statistics did not (CFI = 0.888, TLI = 0.826, and RMSEA = 0.224). For mental fatigability, although three goodness-of-fit values were acceptable (CFI = 0.948, TLI = 0.919, and SRMR = 0.057), the RMSEA value (0.149) did not indicate good model fit. However, each item coefficient was statistically significant (> 0.5), and the K-PFS was therefore found to be valid from a theoretical perspective. Conclusion This study provides meaningful information on the reliability and validity of the K-PFS instrument, which was developed to meet an important need in the context of breast cancer survivors. Additional research should examine its test–retest reliability and construct validity with performance measures.

Association of fatigue, inflammation, and physical activity on gait speed: the Long Life Family Study

et al. 2021

View full text Add to dashboard Cite

Background: Fatigue, inflammation, and physical activity (PA) are all independently associated with gait speed but their directionality is not fully elucidated.Aims: Evaluate the bidirectional associations amongst fatigue, inflammation, and PA on gait speed. Methods:This cross-sectional study included probands (n=1,280, aged 49-105) and offspring (n=2,772, aged 24-88) in the Long Life Family Study. We assessed gait speed, fatigue with the question "I could not get going", inflammation using fasting interleukin-6 (IL-6) and high sensitivity C-reactive protein (CRP), and self-reported PA as walking frequency in the past two weeks. The two generations were examined separately using linear mixed modeling.Results: Lower fatigue, lower IL-6, and greater PA were all associated with faster gait speed in both generations (all p<0.05); lower CRP was only associated with faster gait speed in the
