JYVASKYLA ÜNİVERSİTESİ AKTİF YAŞLANMA ÖLÇEĞİ: GEÇERLİLİK VE GÜVENİLİRLİK ÇALIŞMASI
The purpose of this study is to conduct the Turkish validity and reliability analysis of Active Aging Scale (University of Jyvaskyla Active Aging Scale: UJACAS) developed by Rantaten and others (2018). Survey method was used in the research. Participants of the study are residents of Ankara Keçiören Nursing House and members of Turkey Pensioners' Association of Ankara Branch. Also participants consist of 146 people over 65 years of age. Data were collected by demographic information, Active Aging Scale and Satisfaction with Life Scale. IBM SPSS Statistics 23 program and Winsteps program were used to analyze the data. Test-retest reliability coefficient and Cronbach's alpha reliability coefficient values of the scale total and sub-dimensions were found to be over 0.90. In addition, Active Aging Scale(AAS) was found to be a good fit (internal structure validity) and reliable (PSI = 0.97) scale according to the goodness of fit statistics and reliability values of Rasch model. As a result of the analyzes, It was concluded that the scale was adequate to the Rasch model and the total scale score consisted of 4 subscales (Goals, Functional Capacity, Opportunity and Aktivitiy) including one-dimensional active aging implicit structure. 65 years of age and older in Turkey was determined to be a reliable and valid measurement tool that can be used to determine the level of active aging of elderly individuals.
