Participants included 266 individuals aged 55 and over living in Izmir, Turkey. The process of developing the scale includes the following stages: problem identification, item pool creation, expert opinion, form shaping, pilot application, and finalizing the scale. The exploratory factor analysis revealed that the scale consists of 6 different dimensions, and the variance explained by these dimensions was found to be 65.184%. The acceptable values for the scale's fit indicators are as follows: chi(2)/df0.90, IFI > 0.90, TLI > 0.90, CFI > 0.90, RMSEA < 0.08, and SRMR < 0.08. These values indicate an appropriate fit between the model and the data set. It was determined that the scale of factors affecting the joy of life in older adulthood is valid and reliable. The scale consists of six dimensions and 23 items.eninfo:eu-repo/semantics/closedAccessOld AgeJoy of LifeScale DevelopmentPsychological CollapseAdaptation in AgingArticle124WOS:001477427000001Q3
