Excessive use of social networking services (SNS) is known to have a significant negative impact on mental health in university students. In this study, we conducted an online questionnaire survey of university students and analyzed 146 responses in order to clarify the relation between SNS addiction and self-compassion among university students. As a result, it was found that there was a significant negative relationship between SNS addiction and self-compassion in the university students. In addition, the subscales of "self-judgment," "isolation," and "over-identification" were significantly associated with SNS addiction. These results suggest that selfcompassion education may help reduce the deterioration of mental health caused by SNS addiction.

In clinical practice, the attitude of the practice supervisor, such as the nurse or teacher, is important because it influences the learning of the nursing students. Nursing students learn a great deal through the relationships they form with nursing subjects (patients, family members, and other nursing subjects) and through the practice of nursing. The attitudes of practice supervisors, patients, and family members are believed to influence nursing students' confidence and motivation for the next stage of their practice. The purpose of this study was to examine how self-compassion, experiences of praise from practice instructors and patients/families, students' own psychological responses to experiences of praise, and achievement of practice goals affect nursing students' sense of on-the-job practice efficacy. Field practice efficacy consisted of "understanding and helping the subject efficacy," "maintaining relationships with friends efficacy," and "maintaining relationships with instructors and learning attitude efficacy. Multiple regression analysis revealed that the experience of being praised for the student's behavior, such as "being praised for working hard" and "being praised for studying well," had an effect on "understanding and helping the target" efficacy. In addition, psychological reactions such as "I feel motivated," "I am happy," and "I feel confident," which occur as a result of being praised, affected "the efficacy of maintaining relationships with friends. In addition, self-compassion, "experience of being praised for behavior," and "achievement of practice behavior goals" influenced "maintenance of relationship with instructor and learning attitude efficacy. This indicated that nursing students being given positive feedback and verbal praise by practice instructors, patients, and family members influenced their achievement of practice behavior goals and their self-efficacy for their next field practice.
