Summary
This study translated the China Rural Middle-Aged and Elderly Health Literacy Scale (CREHLS) into Turkish. The validated CREHLS is a reliable tool for assessing health literacy in older Turkish adults.
Area of Science:
- Gerontology
- Public Health
- Health Services Research
Background:
- Inadequate health literacy in older adults restricts access to essential healthcare services.
- The "China Rural Middle-Aged and Elderly Health Literacy Scale" (CREHLS) is a key instrument for assessment.
- Adapting and validating health literacy tools for diverse populations is crucial.
Purpose of the Study:
- To translate the CREHLS into Turkish.
- To perform psychometric validity and reliability analyses of the Turkish version of CREHLS.
- To provide a culturally relevant tool for assessing health literacy in elderly Turkish individuals.
Main Methods:
- The CREHLS was translated into Turkish.
- A sample of 338 elderly individuals (mean age 64.8 years, 53% female) from Izmir, Türkiye, participated.
- Psychometric properties were evaluated using reliability and validity analyses, including Confirmatory Factor Analysis (CFA).
Main Results:
- The Turkish CREHLS demonstrated high internal consistency (Spearman-Brown coefficient = 0.935).
- Item-total correlations were strong, generally ranging from 0.7 to 0.8.
- Adequacy for factor analysis was excellent (0.956), indicating robust structural validity.
Conclusions:
- The Turkish version of the CREHLS is a valid and reliable instrument.
- This scale can effectively measure health literacy among elderly individuals in Türkiye.
- The findings support the use of the Turkish CREHLS to improve healthcare access for older adults.

01:21Health Literacy
5.2K
Health literacy is an individual's or a community's capacity to comprehend, receive, read, and use relevant healthcare information and services. The World Health Organization (WHO, 2018) defines health literacy as the cognitive and social skills that determine the ability of individuals to gain access to, understand, and use information in ways that promote and maintain good health. As a result, the WHO helps individuals manage long-term health concerns, participate in preventative...

01:15Drug Dosing: Geriatric Patients
209
Elderly individuals encompass a diverse population with varying degrees of age-related physiological changes. Defining the elderly presents challenges, as the geriatric population is often arbitrarily categorized as individuals older than 65. However, many individuals in this group lead active and healthy lives, with an increasing number surpassing 85 years and falling into the older elderly category. Physiological changes associated with aging impact performance capacity and homeostatic...

01:18Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Excretion
217
In geriatric patients, renal physiology undergoes significant changes, including diminished renal blood flow and a lower glomerular filtration rate (GFR), leading to alterations in medication clearance. Drugs such as aminoglycoside antibiotics, lithium, and digoxin, which rely on glomerular filtration for removal from the body, particularly impact pharmacokinetics. These drugs tend to have slower clearance rates in older adults, necessitating careful dosage considerations.Evaluation of renal...

01:00Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Distribution
215
Drug distribution in the human body is influenced by several factors, including plasma protein concentration, body composition, blood flow, tissue-protein concentration, and tissue fluid pH. Among these, changes in plasma protein concentration and body composition due to aging significantly affect how drugs are distributed within the body. Specifically, aging is associated with a decrease in albumin levels by about 10% and an increase in α1-acid glycoprotein levels. These alterations are...

01:18Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Metabolism
181
Geriatric patients show significant variation in how their bodies process medications, which can change how effective and safe treatments are. The liver is the primary organ where drug metabolism occurs, involving two main types of chemical reactions: phase I and II. Phase I metabolism is driven by the cytochrome P450 enzyme system, which includes key types such as CYP3A, CYP2D6, and CYP2C9. Research indicates that while aging doesn't notably alter the levels or activity of these enzymes, it...

01:29Assessment of the Gastrointestinal System II: Health Perception Pattern
432
Assessing the gastrointestinal (GI) system is a complex process that begins with collecting subjective data. This data, collected through patient interviews, provides crucial insights into the patient's health history, perception patterns, and lifestyle habits, all contributing significantly to GI health.
Health Perception Patterns
Health perception patterns offer valuable insights into a patient's lifestyle habits and how they may impact their GI health. These patterns include:
