Background: ‘Mobile phone addiction’ is considered as a compulsive and addictive disorder in the 21st century, and excessive usage of mobile phone can lead to addiction. Objectives: The present research aims to study construction and psychometric properties of the Mobile Phone Addiction Questionnaire Method: Using the multi-stage random sampling method, 200 subjects (including100 males and 100 females) were selected from among the 3rd-grade high school students in District 1 of Ahwaz city. Results: The results of the factor analysis showed that the Mobile Phone Addiction Questionnaire consisted of 13 questions as well as the three subscales of creativity loss, tendency, and loneliness, and that its reliability and validity enjoy a good fitness. Confirmatory factor structure also confirmed the suggested three-factor model of the Questionnaire. Conclusion:The mentioned questionnaire can be used for diagnosis of mobile phone addiction and performing the related studies.

Children are different regarding the type of activities. Some of them are hyperactive characterized with unwanted, non-purposeful movements. Diagnosis of this disorder needs appropriate and precise methods.
The purpose of this study is to analyze the structure and validity of questionnaires used for the diagnosis of attention deficit hyperactivity disorder.
Research population consisted of teachers of exceptional children and parents of hyperactive children. One hundred people (54 parents and 46 teachers) were selected using multistage and random sampling. Data were collected through questionnaires (exploratory factor analysis).
Exploratory factor analysis indicated that the questionnaires used for the diagnosis of attention deficit/hyperactivity disorder consist of 35 items and 5 factors, including memory and attention deficit (9 items), responsibility and organization (9 items), non-purposeful movements (8 items), cooperating with others (5 items), and impulsivity (4 items). The questionnaire has an adequate reliability (Cronbach's alpha for the entire questionnaire = 0.70, first factor = 0.85, second factor = 0.72, third factor = 0.81, fourth factor = 0.68, and fifth factor = 0.65). To determine the validity of the text, Adult Behavior Checklist (Barkley and Murphy, 1998) was used. Correlation coefficient was estimated as 0.295, which is significant at p<0.003. This is indicative of the adequate validity of the questionnaire.
This study suggests that the questionnaire used for the diagnosis of attention deficit/hyperactivity disorder is effective and has adequate reliability and validity.

Method: 247 (142 females and 105 males) students of Payame Noor University of Ahvaz were selected using randomly multi-stage cluster sampling method. Results: A factor analysis, using the principal components analysis (vaimax rotation) resulted in three factors that consisted of 61/11% of variance. Cronbach's Alpha reliability coeffients (internal consistency) were satisfactory for the whole scale was ./85 (first factor: 0/77 , second: 0/6 & third factor: 0/70. Factor analysis showed that constructed test combined from 3 factor (deliberating procrastination, Physical-mental causing procrastination, and procrastination causing without programming. Validity of this test obtained through relation between Tuckman (1991) questionnaire with constructed test (0/ 35). Conclusion: It can be concluded that the academic procrastination test has a good reliability and validity, and is a useful instrument to assess students' academic procrastination.
