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.

The main purpose of this study was to examine psychometric properties of a short version of the Self-Regulation Inventory (SRI-S) including reliability, validity, and exploratory factor analysis of the SRI-S in Iranian students. Six hundred and seventy six Iranian volunteers (294 males, 382 females) from universities in Iran were included in this study. All participants were asked to complete the SRI-S (Marques, Ibanez, Ruiperez, Moya, & Ortet, 2005), the Eysenck Personality Questionnaire-Revised Short Scale (EPQ-RS; Eysenck, Eysenck, & Barrett, 1985), and the Mental Health Inventory (MHI-28; Besharat, 2009). The results of exploratory factor analysis supported a single general factor of self-regulation and a five factor structure including Positive Actions, Controllability, Expression of Feelings and Needs, Assertiveness, and Well-Being Seeking. The convergent and discriminant validity of the SRI-S were supported by an expected pattern of correlations between the scale and the measures of personality and mental health. All correlation coefficients between the mean scores on the SRI-S and scores of the extraversion, neuroticism, psychological well-being, and psychological distress were statistically significant. Coefficient alpha estimates of internal reliability were between .90 and .97 for the SRI-S subscales. Test-retest reliability of the SRI-S was also calculated at the range of .71-.86. All correlations were statistically significant. It was concluded that the SRI-S can be considered as a reliable and valid scale to measure self-regulation in Iranian samples.
