This study concerns an evaluation of anxiety levels in jailees awaiting trial in a county jail. Detecting anxiety which had been overtly controlled, and apparently hidden called for the use of a projective technique. Such an instrument would have the additional advantage of minimizing the effect of the observer upon the observed.

The development of smartphones packed with applications has brought great convenience to, and improved the quality of, people’s daily lives, but it has also changed people’s behavior. People spend more and more time on mobile phones every day, leaving them distracted, affecting their sleep quality, and thereby giving rise to the concept of smartphone addiction. As a major group of smartphone users, college students have also experienced situations in which the use of mobile phones has decreased their learning efficiency as they try to escape from academic pressure. This article presents quantitative research on college students in Halmstad and aims to explore the connection between smartphone addiction and interaction anxiousness. Data was collected from a sample of 123 smartphone-using college students using an incidental sampling method; questionnaires provided a scale to rate smartphone addiction and interaction anxiousness. Statistical Product and Service Solutions (SPSS) 23 was used to analyse descriptive statistics, Pearson correlation, independent-sample t-test, and regression and so on.  According to the results, smartphone addiction is not common among college students. The overall status of college students’ interaction anxiousness is close to a moderate level. Levels of interaction anxiousness varied significantly depending upon gender, subject and grade. There is a significant positive correlation between smartphone addiction and interaction anxiousness. Interaction anxiousness has a certain predictive effect on smartphone addiction.

The purpose of this study is to determine the levels of anxiety in college freshmen and seniors from the Departments of Science and Art at North Texas State College by using the Taylor Manifest Anxiety Scale. It is hoped that the findings uncovered by this study will be of help to others interested in investigating and exploring this area.
