Psychometric Properties of the Cultural Intelligence Scale in a Saudi Arabian Context

The purpose of this study was to evaluate the psychometric properties of the cultural intelligence scale (CQS) in a Saudi Arabian context. The CQS was administered to a random sample of 553 undergraduate students at Hail University. Results of a confirmatory factor analysis (CFA) supported the four‐factor structure of the CQS: cognitive, metacognitive, motivational, and behavioral. In addition, the results of a second‐order CFA indicated that these four factors can be further collapsed into one general factor. The CQS showed adequate internal consistency and test–retest reliability as well as convergent and discriminant validity. The results further revealed no significant differences between males and females. In sum, results suggest that the Arabic version of the CQS is a reliable and valid instrument for measuring an individual's intercultural intelligence.     

Motivational effects of enhancing expectancies and autonomy for motor learning: An examination of the OPTIMAL theory

The OPTIMAL theory proposes that enhancing expectancies and autonomy facilitate motor performance and learning (Wulf & Lewthwaite). Present study with two experiments aimed to examine this proposition by using a modified dart throwing as motor task. In both experiments, motor learning (i.e., retention test) was enhanced by practice conditions, which enhance expectancies for future performance and support learners’ autonomy. Moreover, they led to significantly superior self-efficacy scores during all acquisition phase, retention, and transfer tests. Findings of the present study provided support for propositions of the OPTIMAL theory. Results are discussed in terms of motivational aspects of enhancing expectancies and autonomy and their role on facilitating motor learning.     

Psychometric Properties of the Persian Version of Spiritual Well-Being Scale in Patients with Acute Myocardial Infarction

The purpose of this study was to assess the psychometric properties of the Persian version of Spiritual Well-Being Scale (SWBS) in patients with acute myocardial infarction. A multisite, cross-sectional survey was employed to determine the instrument’s reliability (Cronbach’s α and construct reliability) and validity (face, content, and construct). Using systematic sampling of adult outpatients at primary care clinic sites in the Qazvin City, Iran (N = 300), it was found that the Cronbach’s alpha and construct reliability of both factors associated with the SWBS were above 0.7. The construct validity of the scale was determined using exploratory factor analysis. The findings supported two factors: relation with God and relation with life. Further investigation through confirmatory factor analysis (eigenvalues of greater than one) confirmed a third factor construct associated with the SWBS. A total of 50.65 % of the variance were explained by these three factors. The overall findings of the study demonstrated that the SWBS is a valid and reliable instrument that has potential utility in future research and clinical practice settings.
