Objectives: The aim of the current study was to develop and evaluate the validity and reliability of Persianself-report version ofSwanson, Nolan and Pelham rating scale (version IV) (SNAP-IV). Method: The study population consisted of all 13 to 15 year-old female students of Shiraz city. To prepare the Persian self-report form of SNAP-IV rating scale, the English text of the scale (parent form) was translated into Farsi. Then some changes were made in the translated text in line with self-report form of the scale. The content, response framework, and expressiveness of Persian form were confirmed by psychologist referees. Then, 290 students who were selected through convenient sampling method completed the questionnaire. To assess construct validity, the Letter-Number Sequencing subtest was conducted on 30 students. Also, SNAP-IV rating scale (parent form) was given to the parents of these 30 students. Data were analyzed using descriptive statistics (mean, standard deviation and skewness), Pearson’s correlation and exploratory factor analysis. Results: The results of the exploratory factor analysis revealed two distinct factors of inattention and hyperactivity/impulsivity. These two factors explained 38.23% of total variance. Cronbach's alpha coefficient, Spearman-Brown coefficient and Guttman split-half coefficient for inattention dimension were 0.81, 0.81 and 0.80, respectively and for hyperactivity/impulsivity were 0.75, 0.65 and 0.64, respectively. Conclusion: Based on the results, the Persian self-report version of the SNAP-IV can be used for assessing and screening adolescents with attention deficit/ hyperactivity disorder.
