Gender And Age

The 15-item version of the Geriatric Depression Scale (GDS-15) is widely employed to assess depression in old people, but it is unclear if there are biases in the total score depending on respondents’ gender and age. In the current study, we investigated the measurement equivalence of the GDS-15 to provide evidence that the test is a fair screening tool when administered to young-old, old-old, and oldest-old men and women. Item Response Theory-based Differential Item Functioning analyses were applied on a large sample of Italian old people. One item exhibited Differential Item Functioning when comparing men and women, and one item showed Differential Item Functioning across different age-groups. Nonetheless, the magnitude of Differential Item Functioning was small and did not produce any differential test functioning. The gender and age measurement equivalence of the GDS-15 confirms that the test can be used for clinical and research screening purposes.

Elder People

Depression in eldery couldn’t be easily detected because physical complaint was more often than emotional complaint. In severe case, depression could cause suicidal behaviour (Irawan, 2013). Therefore, elderly need assistance to deal with depression, and Emotional Freedom Technique (EFT) is one of the solution. Research design is pre-experimental design, using pre-test and post-test design. Before intervention, Geriatric Depression Scale test were given to one group of elder people. EFT intervention were given two times for four weeks, and Geriatric Depression Scale test were tested after intervention. Population was elder people who fulfill inclusion criterias, and 30 elderly were obatained. The significancy result was 0,000 (α = 0,05), it could be inferred that EFT has a strong relationship to depression scale. EFT could significantly reduce depression scale in elderly, so it can bes used effectively.

The purpose of this study was to examine the Geriatric Depression Scale (GDS) translated into Turkish for its reliability, discriminant validity, and factor structure in a sample of 276 community-dwelling elderly and 30 patients with major depression. One item (Item 5) was discovered to have conceptual difficulty for Turkish elderly and was transformed to negative form. Item 2 was transformed to positive form to keep the number of positive and negative items equal to that in the original GDS. A reasonable time stability with 1-week interval (r:.74) and a high level of internal consistency (α = .91) were observed. Student's t test resulted in a significant discriminant validity for the scale total score. Factor study with principal component analysis and varimax rotation gave rise to a structure with seven factors. Results of the same analysis with two factors were found to be easier to interpret. The first factor was composed of 19 items reflecting “depressive affect and thought content.” The other 11 items representing “decrease in motivation and cognitive functions” loaded in the second factor. In conclusion, the Turkish GDS was found to have reasonable time reliability, high internal consistency, and discriminant validity for Turkish elderly. Its two-factor structure can be used as an informative instrument for epidemiological studies, reflecting two main dimensions of depression in the elderly.
