The study primarily aimed to analyze and scale the items of the WHO Quality of Life Measure (WHOQOL-100) issued by the World Health Organization, and to examine its differential item functioning (DIF) according to Andrich\u2019s Rating Scale Model, on a sample of university students in the Capital Secretariat\u2013 Sana\u2019a.<\/p>\n

The study yielded a number of key findings summarized as follows:<\/p>\n

    \n
  • The Rating Scale Model proved effective in scaling the Quality of Life Measure, with 94 items fitting the model.<\/li>\n
  • All items that fit the model fell within acceptable MNSQ value ranges.<\/li>\n
  • The Yemeni version of the Quality of Life Measure demonstrated strong psychometric properties.<\/li>\n
  • A number of items were identified as exhibiting differential item functioning with respect to gender (male\/female), field of specialization (scientific\/humanities), and type of education (public\/private).<\/li>\n
  • The researcher attributed these differences to the cultural context of Yemeni society.<\/li>\n<\/ul>\n

    In light of these findings, the researcher recommended:<\/p>\n

      \n
    • Adopting the Yemeni version of the Quality of Life Measure to assess quality of life among Yemeni university students.<\/li>\n
    • Conducting further studies on the Quality of Life Measure across different segments of Yemeni society using the Rating Scale Model and other Item Response Theory (IRT) models, given their objectivity.<\/li>\n<\/ul>\n

      The dissertation defense was attended by a number of academics, researchers, and specialists, students, colleagues, and the researcher\u2019s family.<\/p>\n
