psychometric evaluation of the persian academic major satisfaction scale (p-amss) in iranian nursing students

Background & objective: the aim of this study was to assess the validity of the persian version of the academic major satisfaction scale (p-amss) among iranian nursing students.material & methods: a cross-sectional study was carried out from january to march 2023. a total of 231 undergraduate nursing students completed demographic information and the p-amss. the data were analyzed using exploratory (efa) and confirmatory factor analysis (cfa).results: the mean (± sd) score of academic major satisfaction among nursing students was 25.47 ± 6.4. the efa results revealed a single factor that accounted for 63% of the total variance. the cfa results indicated a good fit (χ2(6) = 8.53, p = 0.202, cmin/df = 1.422, cfi = 0.99, nfi = 0.99, tli = 0.99, rmsea (90% ci) = 0.043 [ 0.00;0.1]). the p-amss demonstrated good internal consistency and reliability (α=0.907; ω=0.921). measurement invariance was confirmed across gender.conclusion: the p-amss, consisting of 6 items, is a brief scale with strong psychometric properties suitable for evaluating academic major satisfaction among iranian nursing students.
