Abstract

Aim: The main purpose of the present study is to determine the psychometric properties of the life orientation test of Scheier, Carver and Bridges (1994) among Iranian women. Method: The correlation method was used to investigate the factorial structure of the LOT. About 400 individuals including the mothers of female school students in region 1 of Tehran participated in the study. At first, 120 women answered the LOT 10 participants per each variable. Then 200 women answered the LOT, stress assessment scale Royeli, Rosch, Jaryka and Vaughn (2005), the satisfaction with life scale Diner, Emmons, Larsen and Griffin (1985) and the list of positive and negative effects Watson, Clark and Tellegen (1988) 20 participants per each variable. Results: The results showed that the LOT is composed of two factors including optimism and pessimism. The results of confirmatory factor analysis showed that the two-factor structure of the LOT had a good fit to the data. Moreover, the results of correlation between the optimism and pessimism dimensions with the LOT were 0.33 and 0.35, and with positive affect 0.33 and -0.20 and with negative affect -0.22 and 0.26 respectively, and with cognitive assessments including threat -0.20 and 0.30, challenge 0.18 and -0.20 and resources 0.22 and 0.17. The internal consistency coefficients of optimism and pessimism were 0.88 and 0.77 respectively (P=0.001). Conclusion: The LOT is a valid and reliable scale to measure the preferred style of Iranian women in predicting future positive and negative events.
