“…The sample sizes in 11 studies [ 7 , 8 , 53 , 73 , 76 – 79 , 81 , 85 , 92 ] were relatively small: the group sizes (TG and CG) ranged from 10 to 24 participants. The most frequently studied research populations were healthcare professionals (12 studies) [ 7 , 53 , 73 , 76 , 77 , 79 – 81 , 84 , 86 , 90 , 91 ] (e.g., nurses, nurse aides, nursing leaders, physicians, social workers, psychologists, psychotherapists, physical therapists, psychiatrists) and teachers (five studies) [ 75 , 83 , 85 , 88 , 89 ]. Five studies [ 7 , 8 , 79 , 81 , 85 ] involved participants with the same occupation; four studies [ 83 , 85 , 88 , 89 ] investigated respondents from related occupations (i.e., elementary, secondary, or high school teachers).…”
