Evaluating of Biofeedback Training to Reduce College Students and Employees’s Anxiety

[[abstract]]Recently, people feel various stress in their daily life. When faced with these stress, people often use some kind of coping strategy that not only ineffective but also prove negtive and harmful result. There have some kind of useful therapy in professional area, especially biofeedback training. however, according to all kind of study, whether biofeedback training can reduce anxiety or not, still not consistently result. So, this stduy controlled some potential confusion variables that investigate college students and employees are use biofeedback training to controlle thair respiratory rate, heart rate and heart rate variability, whether reducing anxiety level or not . This study use pretest-posttest equivalent-group design. Experiment 1 recruited 30 college students with anxiety problems. Participants were randomly assigned to the biofeedback group (10 members, six weeks of biofeedback training), relaxation training group (10 members, six weeks of relaxation training) or control group (10 members, no intervention) . Biofeedback group recive biofeedback trianing for six weeks, once a week, 30 minutes every time. Out the experiment room, Participants need to do biofeedback training homework at least once a week. Relaxation training group recive relaxation training for six weeks, once a week, 30 minutes every time. Out the experiment room, Participants need to do relaxation training homework at least once a week. Control group are waiting for six weeks. Experimental tools include pretest-posttest Beck Anxiety Inventory scores, respiratory rate, heart rate and heart rate variability, and then analyze descriptive statistics and ANOVA. Experiment 2 recruited 30 employees with anxiety problems. Experiment 2's laboratory procedures, tools, statistical analysis are the same as Experimental 1. Both College Students and employees's anxiety scores appear significant differences between biofeedback group and control group. Compare with control gurop, biofeedback training can significant reduceing mental anxiety level. However, among the three groups, respiration rate, heart rate and heart rate variability are no significant differences. Compare with three groups, biofeedback training can not significant improving physical anxiety symptoms. According to results, college students and employees can effectively reduce mental anxiety level by biofeedback training. however, biofeedback training can not significant improving physiological symptoms of anxiety, such as respiratory rate, heart rate and heart rate variability. discussion about participant characteristics, number of participants, experimental design and statistical analysis, and then to suggest future recommendations
