Impact of Sociodemographic, Psychological, and Quality of Life Factors on Dual-Task Performance in Elderly Iraqis

"The study involves several assessments to evaluate the impact of various factors on dual-task performance in elderly individuals:~1. Sociodemographic Assessment: Collection of data on age, gender, education, income, marital status, and other relevant factors.~2. Psychological Assessment: Use of the Depression Anxiety Stress Scales-21 (DASS-21) to measure levels of depression, anxiety, and stress.~3. Quality of Life Assessment: Utilization of the World Health Organization Quality of Life Brief Form (WHOQOL-BREF) to assess physical health, psychological health, social relationships, and environment.~4. Dual-Task Performance Evaluation: Measurement of the ability to perform a cognitive task (counting backward by threes) simultaneously with a motor task (Nine-Hole Peg Test). The dual-task cost (DTC) is calculated to quantify the impact of cognitive load on motor performance."
