Abstract
Item Parameter Drift occurs over time for various reasons; when test items lose their initial characteristics, such as difficulty and discrimination parameters. Including cases of item parameter drift are revealed, excessive repetition, changes in the education system, and the position of items and the parameters of poor initialization. Item parameter drift causes of the invariance to be violated. There are two types of uniform (change of discrimination parameter) and non-uniformity (change of difficulty parameter) drift. Conceptually and methodologically, this concept is parallel to the concept of differential functioning, with the difference that instead of group differences the periods are examined. In order to after observing the undimensionality, with a little change, the recognition of differential item functioning methods is used. After identifying the drift, it must be determined whether changes in the content, motivation conditions, response time and place of the item are compared with when the item was created. If any of these conditions exist, the item must be removed from the set of items or be reset to the parameter.

Abstract
The purpose of the present study was to investigate the factor structure and internal consistency of the Harman-Jones (2011) attitude toward the emotion scale (ATES) among the highschool grade 2 students in the academic year of 2018-2019. The statistical population of this study includes all second-grade students in Tehran and a sample of 252 high school students in Fatemiyeh high school in the 6th area of 14th region city of Tehran and the tool used to measure Harman-Jones's attitude toward the emotion. The findings of the exploratory analysis indicated that this scale is by the culture of Iranian adolescents, covering five factors of attitude toward anger, sadness, agony, fear, and pleasure, which together account for 58.92% of the total variance. The items related to these five factors have a T value of above 1.96 and a useful load factor of more than 0.4 and a standard load of more than 0.3. The fitting indices were also reached to desirable proportions, and since RMSEA is less than 0.08, the relative chi-square is less than 3, and the GFI, NFI, CFI, and IFI fit index is 0.9, so the 5-factor model discovered in the analysis Exploration has been confirmed in the confirmation analysis and is consistent with the culture of Iranian adolescents over 16 years of age. Also, each of the five factors has an alpha value higher than 0.7, which is consistent with internal consistency.

Abstract
Providing a valid scale for measuring compassion for others in Iranian society is part of the research needs. The purpose of this study was to investigate the validity and reliability of the Sussex-Oxford Compassion for Others Scale (SOCS-O) in a sample of Iranian married individuals, who lived in Iran in the second half of 1399 and the first half of 1400. 315 Iranian married people (265 females and 50 males) were selected by convenience sampling method and responded to the Sussex-Oxford Compassion for Others Scale (SOCS-O; Gu et al., 2020). Exploratory and confirmatory factor analyses were used to evaluate the construct validity. The results of exploratory factor analysis showed the four-factor structure for the scale of compassion for others in Iranian society, which differed from the main model of the scale in terms of factor and item. Confirmatory factor analysis supported the 4-factor structure and the indicators showed acceptable model fit. Cronbach's alpha of the whole scale was 0.90 and the alpha coefficients of factors were between 0.71 and 0.86, which indicates the desired internal consistency of this scale in Iranian society. The results of this study show the desired validity and reliability of the Persian version of this scale and provide a reliable tool for measuring compassion for others to experts.
