This study examined the effects of song-based group music therapy on the exercise stress and positive psychological capital of youth soccer players. Eighty youth soccer players were assigned to either a song-based music therapy group or a control group. For the analysis of the effects of song-based group music therapy, the Exercise Stress scale and the Athlete Positive Psychological Capital scale were administered before and after the intervention. The collected data were analyzed using an independent sample t test and paired t test. The results were as follows. First, the experimental group showed a significantly lower posttest score on the exercise stress measure than the control group (p < .01). The control group showed a significant increase from pretest to posttest on the exercise stress measure (p < .05). Second, the experimental group scored significantly higher at posttest than the control group on the positive psychological capital measure (p < .01). The control group demonstrated a statistically significant decrease from pretest to posttest on the positive psychological capital scale (p < .05). The results suggest that song-based group music therapy is an effective treatment method that lowers exercise stress and raises positive psychological capital of youth soccer players.

The aim of this study is to investigate the demographical differences in technostressors(cause technological stresses). Although previous studies have been conducted to investigate the factors that affect technostress, little studies have examined the differences in demographic factors. Therefore, this study empirically attempts to investigate how level of technostressors differ by demographic factors. Independent sample t-test was used to identify differences after dividing sample into two groups. The technostressors used in this work are work overload, life invasion, complexity of technology, job insecurity, pace of technological change. We found that, sex and position show a significant difference in pace of technological change. In the educational level, there is a difference between work overload. Work overload, life invasion, complexity of technology, and pace of change show differences in age group. In computer knowledge, there are differences in complexity technology, job insecurity, and pace of change. On the other hand, there is no difference in computer using hours. Conclusions and implications are discussed in final section.
