Investigating the Reliability and Validation of Luchiano and His Collegue's Thought Control Ability Questionnaire

According to pervious researches it seems that thought control ability is a one-dimensional trait and it differs from one person to another. The aim of the current study was to investigate the reliability and validation of Thought Control Ability Questionnaire –TCAQ- (Luchiano et al.، 2005) among students. The statistical population of the study included all the students of psychology and educational sciences، in the University of Isfahan. 275 students were selected as sample through simple random sampling and responded to TCAQ and Penn State Worry Questionnaire-PSWQ- (Meyer et al.، 1990). Factor analysis and correlation coefficient used for analyzing data. Findings indicated that factor analysis with one dimension explains 43. 7 percent of variance and the factor loadings of 23 items is higher than 0. 59 (P<0. 01) and therefore suitable. Concurrent validity of Thought Control Ability Questionnaire with Penn State Worry Questionnaire was confirmed (P<0. 01). Also، the results showed that men compared to women and old people compared to younger people have higher thought control (P<0. 01). According to findings، researchers can use a new and short instrument that makes comparing and assessing individual’s thought control easier.
