Background The rate of traumatic brain injuries (TBIs) due to the accidents is high around the world. Patients with mild TBIs may suffer from some psychological disorders, including aggression, and mental fatigue, and thus their quality of life decreased. Among different treatments for TBI, two treatments, namely transcranial direct current stimulation (tDCS), and mindfulness-based stress reduction (MBSR) have shown to be effective. Therefore, this study aimed to compare the effects of these two treatments on mental fatigue, aggression and quality of life in mTBI patients. Materials and methods This randomized controlled trial study was conducted on 48 TBI patients referred to emergency and neurosurgery departments of Shahid Beheshti Hospital, Kashan, Iran. They were selected using the convenience sampling method. Data were collected using the mental fatigue scale, the World Health Organization Quality of Life-BREF (short version), and the Buss–Perry Aggression Questionnaires. Then, the data were analyzed using a Mixed Repeated Measures ANOVAs, and the Levene and Kolmogorov–Smirnov tests by SPSS-23 software. Results The mean age of patients in the three groups of MBSR, tDCS and control were 69.38 + 6.11 (25% male), 25.40 + 12.11 (25% male) and 69.37 + 0.2 (18.8% male), respectively. There was no significant difference between the three groups in terms of mental fatigue, quality of life and aggression (P < 0.05). In addition, the results showed that there was a significant difference between the main effect of time and the interaction between time and group (P < 0.001). Conclusions Both MBSR and tDCS methods are effective in reducing the mental fatigue and aggression and increasing quality of life of mTBI patients; MBSR treatment, as indicated in the present study, can be more effective than tDCS in patients with mTBI.

Compensatory strategies play an important role in second language (L2) processing because of limited language knowledge and ensuing anxiety and could help assure understanding and void communication breakdown. Previous studies about compensatory strategies largely adopt laboratory settings and neglect the strategies in authentic oral communication. Accordingly, the present study investigated compensatory strategies used by Chinese university students in online videoconferences with their US peers during a five-week virtual exchange project. We interviewed 27 Chinese students twice, once after the first-week videoconference, the other after the last-week videoconference. The English as a Foreign Language (EFL) learners in this study could adopt compensatory strategies of different levels. Their strategy use, however, was not flexible enough as several types of strategies were repeatedly used, while other types were rarely implemented. The virtual exchange could help the EFL learners employ compensatory strategies more often, of higher levels, and with increased immediacy. The results can help to establish more targeted English teaching and learning.

Background: The rate of traumatic brain injuries (TBIs) due to the accidents is high around the world. Patients with mild TBIs may suffer from some psychological disorders, including aggression, and mental fatigue, and thus their quality of life decreased. Among different treatments for TBI, two treatments, namely transcranial direct current stimulation (tDCS), and mindfulness-based stress reduction (MBSR) have shown to be effective. So, this study aimed to compare the effects of these two treatments on mental fatigue, aggression and quality of life in mTBI patients.Materials and methods: This randomized controlled trial was conducted on 2000 TBI patients referred to emergency and neurosurgery departments of Shahid Beheshti Hospital, Kashan, Iran, in 2017. They were selected using the convenience sampling method. Data were collected using the mental fatigue scale, the World Health Organization Quality of Life- BREF (short version), and the Buss-Perry Aggression Questionnaires. Then, the data were analyzed using a Mixed Repeated Measures ANOVAs, and the Levene and Kolmogorov-Smirnov tests by SPSS-23 software.Results: Data were collected from 48 patients with mTBI. The mean age of patients in the three groups of MBSR, tDCS and control were 69.38 + 6.11 (25% male), 25.40 + 12.11 (25% male) and 69.37 + 0.2 (18.8% male), respectively. There was no significant difference between the three groups in terms of mental fatigue, quality of life and aggression (P <0.05). Also, the results showed that there was a significant difference between the main effect of time and the interaction between time and group (P <0.001).Conclusions: Both MBSR and tDCS methods are effective in reducing the mental fatigue and aggression and increasing quality of life of mTBI patients; MBSR treatment, as indicated in the present study, can be more effective than tDCS in patients with mTBI.Trial registration: Thailand Registry of Clinical Trials, TCTR20180827003 Registered on August 24, 2018.
