AI Article Synopsis

  • The study aimed to assess the reliability of the Two-dimensional Mood Scale (TDMS) for evaluating mood in elderly patients with dementia.
  • It involved 100 participants and measured various mood states, calculating reliability scores using intraclass correlation coefficients (ICC), minimal detectable change (MDC), and internal consistency through McDonald's omega.
  • Results showed generally acceptable reliability for the TDMS, with ICC values ranging from 0.54 to 0.74 and MDC values indicating the precision of mood state changes in this population.

Article Abstract

The purpose of this study was to evaluate the reliability of the Two-dimensional Mood Scale (TDMS) for mood assessment among older adults with dementia. The study included 100 elderly patients with dementia admitted to two hospitals. For each mood state measured by the TDMS, the intraclass correlation coefficient of agreement (ICC) was calculated to evaluate test-retest reliability. Scores corresponding to the minimal detectable change (MDC) in each mood state at the individual level (MDC) was also calculated to evaluate measurement error, while McDonald's omega was calculated to evaluate internal consistency. The TDMS ICC was 0.54 for vitality, 0.74 for stability, 0.70 for pleasure, and 0.55 for arousal. The MDC was 6.89 for vitality, 5.88 for stability, 9.96 for pleasure, and 4.11 for arousal. McDonald's omega ranged from 0.60 to 0.84. The TDMS has generally acceptable reliability for the self-assessment of mood states by older adults with dementia.

Chronic back pain (CBP) is a global health concern with significant societal and economic burden. While various predictors of back pain chronicity have been proposed, including demographic and psychosocial factors, neuroimaging studies have pointed to brain characteristics as predictors of CBP. However, large-scale, multisite validation of these predictors is currently lacking.

Survivorship after pediatric critical illness is high in developed countries, but many suffer physical morbidities afterwards. The increasing focus on follow-up after critical illness has led to more pediatric studies reporting muscle mass changes (using ultrasound), albeit with different results. A systematic literature review was undertaken examining muscle mass changes, assessed by ultrasound of the quadriceps femoris muscle in children who are critically ill.

In the Philippines, the co-occurrence of two or more types of malnutrition in an individual, also known as intra-individual double burden of malnutrition (DBM), has rarely been investigated. This study aimed to determine the prevalence of and the factors associated with DBM at the individual level among Filipino women of reproductive age (WRA) using the data collected from the 2018 Philippine Expanded National Nutrition Survey. For this study, intra-individual DBM was defined as the co-existence of overweight or obesity and anemia in an individual.
