Marvin Zuckerman's Work on Dimensions of Sensation Seeking Reveals Four

Marvin Zuckerman's work on dimensions of sensation seeking reveals four dimensions to this trait: (1) thrill and adventure seeking susceptibility to boredom (e.g., being easily bored by predictable experiences and people) . These dimensions are theoretically independent. A researcher was interested in designing a new questionnaire to measure sensation seeking. A 16-item questionnaire using a 5-point Likert scale (1 = strongly disagree, 2 = disagree, 3 = neither, 4 = agree, 5 = strongly agree) was devised and given to 750 people. Based on the SPSS output below, what could you conclude?
