Given the intergenerational changes in current societies, it is important to have an appropriate tool to examine the personal values of adolescents in order to identify and meet their needs.Therefore, this study investigated the psychometric properties of the Personal Values Questionnaire and its relationship with personality organization in adolescents residing in Tehran during the2023-2024academic year.This research was fundamental in purpose and descriptive in methodology. The target population comprised all secondary school adolescents in Tehran during the 2023-2024academic year. A multi-stage cluster random sampling technique was employed, resulting in a sample of 356 adolescents. The sample individuals responded to the 21-item Personal Values Questionnaire(PVQ)by Schwartz et al.(2001)and the37-item Inventory of Personality Organisation (IPO) by Kernberg (2001).Data analysis was conducted using confirmatory factor analysis(CFA), Cronbach's alpha, Pearson correlation coefficients, and regression analysis, performed within AMOS24 software.The results indicated that the items within each of the ten components of the PVQdemonstrated acceptable capacity to measure their respective constructs, and that each component also exhibited acceptable capacity to measure the four higher-order dimensions of personal values.In the results of confirmatory factor analysis, it was found that the items of each of the ten components of the Personal Values Questionnaire have acceptable power to measure those components and each of the components also has acceptable power to measure the four dimensions of personal values (protection, self-enhancement, openness to change, self-transcendence)(df/2=2.39, CFI=0.917, GFI=0.918, AGFI=0.868 and RMSEA=0.062).It was also found that the correlation coefficients between the components of the Personal Values Questionnaire and the components of personality organization are negative and significant. Based on this finding, it can be said that the Personal Values Questionnaire has concurrent validity. According to the results of the present study, it can be said that the PVQ is a suitable tool for examining the personal values of adolescents in Iranian society.
