The Abrams geriatric self-neglect scale: introduction, validation and psychometric properties.

ABSTRACT: OBJECTIVE:Self-neglect is an imprecisely defined entity with multiple clinical expressions and adverse health consequences, especially in the elderly. However, research has been limited by the absence of a measurement instrument that is both inclusive and specific. Our goal was to establish the psychometric properties of a quantitative instrument, the Abrams Geriatric Self-Neglect Scale (AGSS). METHODS:We analyzed data from a 2007 case-control study of 71 cognitively intact community-dwelling older self-neglectors that had used the AGSS. The AGSS was validated against two "gold standards": a categorical definition of self-neglect developed by expert consensus; and the clinical judgment of a geriatric psychiatrist using chart review. Frequencies were examined for the six scale domains by source (Subject, Observer, and Overall Impression). Internal consistency was estimated for each source, and associations among the sources were evaluated. RESULTS:Internal consistency estimates for the AGSS were rated as "good," with the Subject responses having the lowest alpha and omega (0.681 and 0.692) and the Observer responses the highest (0.758 and 0.765). Subject and Observer scores had the lowest association (0.578, p < 0.001). Using expert consensus criteria as the primary "gold standard," the Observer and Overall Impression subscales were "good" at classifying self-neglect, while the Subject subscale was "fair." CONCLUSIONS:The AGSS correctly classified and quantified self-neglect against two "gold standards." Sufficient correlations among multiple sources of information allow investigators and clinicians to choose flexibly from Subject, Observer, or Overall Impression. The lower internal consistency estimates for Subject responses are consistent with self-neglectors' propensity to disavow symptoms. Copyright © 2017 John Wiley & Sons, Ltd.

Project description:BackgroundAlzheimer's disease (AD) is the most frequent cause of cognitive impairment. Community knowledge of the disease has proven to be a very important aspect of the development of interventions and the evaluation of their effectiveness. However, it is necessary to have standardized and recognized tools in different languages. The aim of the current study was to develop a cross-cultural adaptation of the Spanish Dementia Knowledge Assessment Scale (DKAS-S) and to assess their psychometric properties with cohorts of health students and professional and non-professional caregivers of AD patients from several regions of Spain.MethodsWe developed and translated the DKAS into Spanish following the forward-back-forward translation procedure. Then, we performed a cross-sectional study to assess the validity, reliability and feasibility of the DKAS-S. We also performed an analysis to obtain test-retest reliability measures. The study was performed in four medical centres across three regions in Spain. From May to September 2019, we administered the scale to students, professional and non-professional caregivers; including a subgroup of non-professional caregivers of patients with early-onset AD (< 65 years).ResultsEight hundred forty-six volunteer participants completed the DKAS-S: 233 students (mean age 26.3 ± 9.2 years), 270 professional caregivers (mean age 42.5 ± 11.7 years) and 343 non-professional caregivers of AD patients. (mean age was 56.4 ± 13.16). The DKAS-S showed good internal consistency (Cronbach's α = 0.819) and good test-retest reliability (time 1: 28.1 ± 8.09 vs time 2: 28.8 ± 7.96; t = - 1.379; p = 0.173). Sensitivity to change was also significant in a subgroup of 31 students who received education related to AD and dementias between each administration (time 1: 25.6 ± 6.03) to (time 2: 32.5 ± 7.12; t = - 5.252, p = 0.000). The validity of the construct was verified by confirmatory factor analysis, although there were challenges in the inclusion of some items in the original 4 factors.ConclusionsThe 25-item DKAS-S showed good psychometric properties for validity and reliability and the factorial analysis when it was administered to a population of students and professional and non-professional caregivers. It was a useful instrument for measuring levels of knowledge about dementia in Spanish population.

Project description:Positive mental health is crucial to individuals' total well-being and especially to their emotional, psychological, and social functioning. To assess the positive aspects of mental health, the Positive Mental Health Scale (PMH-scale) is being used as one of the most significant and practical short unidimensional psychological tools. However, the PMH-scale has not yet been validated for the Bangladeshi population nor has it been translated into Bangla. Therefore, the purpose of this study was to investigate the psychometric properties of the Bangla version of PMH-scale and validate it with the Brief Aggression Questionnaire (BAQ) and Brunel Mood Scale (BRUMS). The sample of the study consisted of 3145 university students (61.8% men) aged from 17 to 27 (M = 22.07, SD = 1.74) and 298 general population (53.4% men) aged from 30 to 65 (M = 41.05, SD = 7.88) of Bangladesh. The factor structure of the PMH-scale as well as measurement invariance for sex and age (age ≤30 years; age >30 years) were tested, using the confirmatory factor analysis (CFA). The CFA revealed that the originally proposed unidimensional model of PMH-scale had a good fit in the current sample which confirms factorial validity of the Bangla version of PMH-scale. The value of Cronbach's alpha (for both groups combined α = 0.85; for the student sample α = .85; and for the general sample α = .73) ensured the high internal consistency of the items. Concurrent validity of the PMH-scale was confirmed through the expected correlation with aggression (BAQ) and mood (BRUMS). The PMH-scale was also partially invariant over groups (student, general, men and women) indicating that the PMH-scale is equally applicable to student, general, men and women population. Therefore, this study tells us that the Bangla version of PMH-scale is a quick and easy-to-administer tool for assessing positive mental health in different groups of people in Bangladeshi culture. This work will also be useful for mental health studies in Bangladesh.
