Introduction: Although different tools have been designed to measure mindfulness, none of these tools comprehensively examined the dimensions of mindfulness together. Moreover, they were related to a specific age group only. In response to this research gap, the Droutman et al.'s Mindfulness Scale (AAMS) is designed with 19 items to measure four dimensions of mindfulness for both groups of adolescents and adults. The aim of the present study was to investigate the psychometric properties of Droutman et al.'s Mindfulness Scale in two groups of students. Methods: The present study, in the form of a psychometric study, sought to investigate the validity and reliability of the Droutman et al.'s Mindfulness Scale. The study participants were 525 people (220 university students and 305 school students) who were studying in 1397-98 academic year and completed Droutman et al.'s Mindfulness Scale, Gilbert et al.'s Social safeness and pleasure scale, Keyes & Magyar-Moe Emotional well –being scale, and Kraaij & Garnefski behavioral emotion regulation questionnaire. The Data were analyzed using correlation coefficient, Cronbach's alpha coefficient and confirmatory factor analysis. Results: The results of confirmatory factor analysis confirmed the four factors of attention and awareness, being non- reactive, being non-judgmental and being self- accepting. The results of correlation with other tests also confirmed the convergent validity of the scale. The Cronbach's alpha method was used to determine the reliability of the scale, with all coefficients indicating an acceptable internal consistency of the subscales and the total score of the scale. Conclusion: The results show that the Droutman et al.'s mindfulness scale has a very good validity and reliability in Iranian university and school students, and It is effective in measuring mindfulness in the four dimensions mentioned. The results are based on research and theoretical evidence.

This research has been carried out with the aim of study psychometric properties of Sampad’s Entrance Tests using Rasch measurement model. In this study, answer sheets of 2872 students(1542 boys and 1330 girls) were selected by means of multistage random sampling. The data were analysed using the unidimensional Rasch simple logistic model with Winsteps software . The results revealed that all items of the test showed good model–data fit. The range of items location parameter were -2.48 to 1.83. Also the showed that targeting is not good. On the whole, the findings of this research showed that the Sampad’s Entrance Test does not have good measurement qualities, so should not be used to select students for Talent middle schools.This research has been carried out with the aim of study psychometric properties of Sampad’s Entrance Tests using Rasch measurement model.

Backgrounds: Recent studies showed that beside the person with addiction great number of person are with personality in the risk of addiction, but the measurement of this characteristic in Iran needs to instrument that similar to culture of this country.
Objectives: The purpose of this study was the Preparing and normalization of addiction potential scale among students of Tehran universities.
Methods: after design, scale indicating 60 item were administrated to a sample of 90 addict and 540 students of Tehran universities.
Result: this scale distinguished between addict and non addict students. The reliability coefficients was estimated through internal consistency using cronbach alpha coefficient and was (α=0.88) . The validity of this scale investigated in two different ways: construct validity and face validity. The result obtained from analysis showed this scale consists of ten factors and is highly valided. T score was calculated for normalization.
Conclusion: overall indicated that the use of the addiction potential scale in researches, therapy and screening is useful.
