Abstract
Background and Objective: To measure the mental strength and ability of human and structures that exist in field of positive psychology some instruments are required. The aim of the present study was to investigate the psychometric properties of Simpson's Hope Scale in Iranian university students.
Methods: In this descriptive-survey research 1000 students of the 18-34 age group and the 23.9±5.13 mean were selected through categorical cluster sampling method from among different Iranian universities, and the participant answered Snyder's Hope Scale, Oxford Happiness Scale, Hardiness Scale, Beck Hopelessness Inventory, Riff's Psychological Well-being Scale as well as Simpson's (1999) Hope Scale (with minor changes).
Results: Of meaningful significance (p<0/01) were Coefficients of Cronbach's Alpha (0.94), split-half (0.85), convergent validity (with Hardiness, (0.40), Happiness, (0.64), Psychological Well-being, (0.47), divergent validity (with Hopelessness, -0.25). Exploratory factor analysis showed that 40-items Hope scale for adults had five latent factors that explain 56% of the variance. Second order confirmatory factor analysis indicated that the five factors had high factor loadings on one latent factor and therefore six factors model was fitted with the data (AGFI=0.93, RMSEA= 0.037, NFI=0.98).
Conclusion: The results showed that this test has high reliability and validity and can be used in other researches as well.
