Canadian subjects (N = 120) completed four psychological scales. Three of the scales were directly related to risk-taking behavior. These were the Sensation Seeking Scale (SSS V; Zuckerman, 1979), the Tension Risk Adventure Inventory (TRAI; Keinan et al., 1984) and the Telic Dominance Scale (TDS; Murgatroyd et al., 1978). In addition, subjects completed the Desire for Control Scale (DCS; Burger and Cooper, 1979) to investigate the role of desire for control in risk-taking. The results indicated (1) significant differences between age and sensation seeking (2) a four-factor structure for the TRAI following factor analysis with this Canadian sample (3) numerous intra- and inter-scale relationships obtained from correlation analyses of and (4) four major dimensions arising from PCA of the four inventory scales.
