The Psychometric Properties and Standardization of the Scale of Positive and Negative Experience (SPANE) Among Third Grade Female High School Student in Tehran

The purpose of the present study was to standardize and study the psychometric properties (validity and reliability) of the scale of positive and Negative experience. 401 third grade students were multistage cluster randomly selected as sample of the study from high school in Tehran in the academic year 2015-16. The psychometric properties of the scale were assessed by Chronbachʼs Alpha, checking the construct and concurrent validities. The reliability of the scale using Chronbachʼs Alpha, Guttman, Spearman for positive feelings were 0.84, 0.70 and 0.80 and for Negative Feelings 0.78, 0.65 and 0.74 respectively. Also, the concurrent validity obtained by PANAS positive and Negative Feeling stale for positive and negative feelings were 0.87 and 0.83 respectively. The results of the factor analysis show that this scale holds two factors with suitable fit indexes. Therefore, the sale of positive and negative experience enjoys a desirable validity and reliability and can be used as a suitable diagnostic instrument
