Turkish Validity and Reliability of The Self-Perceived Health Scale: How Do Quality of Life, Psychological Well-Being, and Health Promotion Behaviors Affect Perceived Health in Older Adults?

The study aims to validate and assess reliability of the Turkish version of a tool for Self-Perceived Health (SPH) in older adults, while exploring its associations with quality of life (QoL), psychological well-being (PWB), and geriatric health promotion (GHP) behaviors. Methods included scree plots, Kaiser-Meyer-Olkin measure, Bartlett’s test, variance percentage, and reliability statistics (Cronbach’s alpha, Spearman-Brown coefficient, Hotelling’s T-squared test, and Bland-Altman plots). Pearson correlation and linear regression analyses were conducted. 1202 participants (mean age: 66.62 ± 6.43 years, 58.9% female) took part. Factor loadings ranged from 0.471 to 0.941, with Cronbach’s Alpha measuring at 0.946. Bland-Altman analysis indicated interchangeability between SPH and SF-12. Regression analysis revealed several factors influencing SPH: being male, transitioning to metropolises, employment, improved economic status, non-smoking, alcohol consumption, regular medication use, and the increase in PWB and GHP behaviors. The study confirms the Turkish SPH scale's validity and reliability, shedding light on factors impacting older adults' health perceptions.
