Validity and reliability of Bayer Activities of Daily Living (Bayer- ADL) scale in the Iranian elderly dementia population: Is there distinguish between illiterate and literate demented in functional dependency?

This validation study is discriminant and concurrent, with the Bayer-Activities of Daily Living (Bayer-ADL) tool among the Iranian elderly dementia illiterate and literate. The tools Bayer-ADL, Global Deterioration Scale (GDS), Mini Mental State Examination (MMSE), ADL-Barthel, and instrumental activities of daily living (IADL) were applied to find Bayer-ADL correlations in 311 dementia outpatients that were ≥60 years old. The Iranian version Bayer-ADL scores between illiterate and literate dementia elderly, based on GDS, observed good discrimination values (0.923 sensitivity and 0.750 specificity) in illiterate people, and excellent discrimination values were achieved (sensitivity 0.919 and 0. 986 specificity) in literate dementia elderly. The suggested cutoff points were 1.79 for illiterate and for the Iranian literate dementia elderly 1.82, based on GDS. Both forms (24 and 25 items) of Bayer-ADL were correlated to GDS, ADL, and IADL. Bayer-ADL is a valid tool to distinguish physical dysfunction between illiterate and literate of the Iranian dementia elderly; however, some revisions in the components are needed for the illiterate elderly. Generally, the findings presented in the Iranian version Bayer-ADL could be useful to both clinical purpose and international studies.

Screening for elder abuse in geriatric outpatients: reliability and validity of the Iranian version Hwalek-Sengstock Elder Abuse Screening Test (H-S/EAST).

The present research seeks the notion of the appropriateness of "Hwalek-Sengstock Elder Abuse Screening Test (H-S/East)", and psychometric properties to analyses cultural aspects of elder abuse in the Iranian community dwellers referred to clinics. In this cross-sectional validation study 364 participants, 60 years and over were selected from outpatient' clinics. The SF-36, GDS-15, and AMT scores were used for concurrent validity. The Brief Abuse Screen for the Elderly (BASE) scale was examined to determine the sensitivity and specificity of the Iranian version H-S/East. The elder abuse rate in participants was 29.4% based on cutoff ≥4, while a significant correlation was found in Iranian version H-S/EAST with depression and SF-36 subscale MCS at P < .01, and four factors observed. Optimal cutoff ≥4 obtained with 82.8% sensitivity and 84.5% specificity. It seems the Iranian version of H-S/East demonstrates concurrent validity and fair reliability in elderly outpatients, while construct validity should be carried out in the Iranian elder illiterate population and other languages/cultures.

Iranian Version of Barthel Index: Validity and Reliability in Outpatients' Elderly.

BACKGROUND: Validation study of Barthel Index for elderly patients being attended in outpatient and rehabilitation clinics in Iran. METHODS: Face-to-face interview with 395 out patients geriatric 60+ years was done in a cross-sectional study. The internal consistency Barthel-ADL was used to approve reliability. Criterion validity and factor analysis were used to verify validity. RESULTS: Reliability the Iranian version BI was significant at 0.938. In criterion validity analysis, the high correlation tools included Functional Ambulation Category (FAC) and Foot and Ankle Ability Measure (FAAM-subscales ADL) at 0.947 and -0.945, respectively. In factor analyses, two domains obtained, the variance of 10 items achieved 69.79%; also, the Item Total Correlation (ITC) of each item was measured. CONCLUSIONS: The Barthel Index shows a good validity and reliability, and recommended to use in the Iranian geriatric outpatients in evaluating physical ability.

Comparison of Two Validation Nutrition Tools in Hospitalized Elderly: Full Mini Nutritional Assessment and Short-form Mini Nutritional Assessment.

BACKGROUND: The aim was to determine validity, reliability, and cutoff of full-mini nutritional assessment (MNA) and MNA-short form (SF) also which one was better for the screening of malnutrition in the Iranian hospitalized elderly. METHODS: In this cross-sectional validation study, 96 hospitalized elderly ≥60 years selected from two hospitals in Tehran. Anthropometric measures (body mass index [BMI], mid-arm circumference [MAC], calf circumference [CC], abdomen, and waist skinfold thickness) and laboratory tests (albumin and hemoglobin levels, and red blood cell count were performed. Nutrition tools (full-MNA and MNA-SF), cognition tool (mini-mental state examination, depression scale (Geriatric Depression Scale15 and activities of daily living (ADL) index (Modified Barthel-ADL) were administered. RESULTS: The full-MNA scores were significantly correlated to measures of MAC, BMI, waist, and CC. The MNS-SF scores were significantly related to measures of MAC, waist, and CC. Serum albumin showed a poor correlation with both tools. At cutoff 24 in full-MNA had a sensitivity 75% and specificity 77.8% and the MNA-SF considered 62.5% sensitivity and 65.3% specificity at cutoff 10.50 to detect well-nourished from malnourished subjects. The internal consistencies of both tools were >90%. In exploratory factor analysis, six components found for full-MNA and two components for MNA-SF. Known group validity of full-MNA was reflected significant differences between geriatric patients with expected higher full-MNA scores and patients with expected lower scores (BMI ≥24 vs. BMI <24 or bed ulcer or assisted food intake). CONCLUSIONS: It seems the Persian version of full-MNA is more appropriate in comparison to MNA-SF for screening malnutrition in the Iranian hospitalized elderly patients.

Psychometric properties of the Persian version of the nutritional form for the elderly (NUFFE) in nursing home residents.

Background: The Nutritional Form for the Elderly (NUFFE) is a newly developed tool. This study aimed to carry out a psychometric evaluation of the Persian version of NUFFE (NUFFE-P) among nursing home residents. Methods: Nursing home participant's aged ≥ 60 years (n=97) were enrolled. The inclusion criteria were residency for at least 6 months in the nursing home, and ability to communicate. Exclusion criteria included cognitive impairment, having depressed mood, severe hearing loss, problems in upper and lower extremities also, history of hospital admission during 6 months before enrollment. Anthropometric measures, laboratory tests, three-day food intake, NUFFE-P version, Mini Nutritional Assessment (MNA), Barthel Index (BI) and Geriatric Depression Scale (GDS-15) were assessed. The relationship between the NUFFE-P and MNA scores was considered as concurrent validity. Results: The Cronbach's alpha coefficient of NUFFE-P tool was 0.76. The intraclass correlation coefficient for the total score between two raters obtained 0.98 (CI 0.97-0.99). The correlation coefficient between the NUFFE-P and the MNA scores was -0.75 (p<0.01). Four factors were extracted for the NUFFE-P in an exploratory factor analyses. Sensitivity 69.8% and 100% and specificity 75.7% and 85.6% were achieved to detect elderly at medium risk (cutoff=6), and at high risk of under-nutrition (cutoff=11) respectively. Conclusion: The NUFFE-P has sufficient psychometric properties in nutritional status screening among the Iranian elderly nursing homes residents.
