mental health, but few controlled trials have evaluated their effectiveness among young people". Although much of the available studies find a high number of mindfulness acceptability among students and teachers, more research needs to be conducted on its effects on well-being and mental health for students. In a firmly controlled experiment, Johnson, Burke, Brinkman, and Wade evaluated "the impact of an existing and widely available school-based mindfulness program". According to their research, "no improvements were demonstrated on any outcome measured either immediately post-intervention or at three-month follow-up". Many questions remain on which practices best implement effective and reliable mindfulness programs at schools, and further research is needed to identify the optimal methods and measurement tools for mindfulness in education. Business Mindfulness training appears to be getting popular in the business world, and many large corporations have been incorporating mindfulness practices into their culture. For example, companies such as Google, Apple, Procter & Gamble, General Mills, Mayo Clinic, and the U.S. Army offer mindfulness coaching, meditation breaks and other resources to their employees to improve workplace functioning. The introduction of mindfulness in corporate settings still remains in early stages and its potential long-term impact requires further assessment. Mindfulness has been found to result in better employee well-being, lower levels of frustration, lower absenteeism and burnout as well as an improved overall work environment. Law Legal and law enforcement organizations are also showing interest in mindfulness: Harvard Law School's Program on Negotiation hosted a workshop on "Mindfulness in the Law & Alternative Dispute Resolution." Many law firms offer mindfulness classes. Prison-programs Mindfulness has been taught in prisons, reducing hostility and mood disturbance among inmates, and improving their self-esteem. Additional studies indicate that mindfulness interventions can result in significant reductions in anger, reductions in substance use, increased relaxation capacity, self-regulation and optimism. Government Many government organizations offer mindfulness training. Coping Strategies is an example of a program utilized by United States Armed Forces personnel. The British Parliament organized a mindfulness-session for its members in 2014, led by Ruby Wax. Scientific research Effects and efficacy of mindfulness practice Mindfulness has gained increasing empirical attention since 1970 and has been studied often as an intervention for stress reduction. Meta analyses indicate its beneficial effects for healthy adults, for adolescents and children, as well as for different health-related outcomes including weight management, psychiatric conditions, heart disease, sleep disorders, cancer care, adult autism treatment, multiple sclerosis, and
