Following a pilot study with a survey, researchers are exploring the relationship of prosocial behavior & health & well being. One feature of prosocial behavior is that it can generate positive emotions which are believed to have beneficial effects on health. To explore this relationship, the researchers design a study in which the participants are randomly assigned to 1 of 3 groups that vary in prosocial activity (ACTIVITY): 1-a group that has no specific intervention (control), 2-a group that is instructed to engage in positive emotional thoughts for one month; and 3-a group that works with a specific volunteer group for 5 hours a week for a month. The following information was collected: Age: recorded in the number of years of age reported on the survey; Gender: male (1) or female (2) as reported on the survey Health rating (Hrate): This is a composite of several measures of health including BMI, heart rate, blood pressure, cholesterol & triglycerides; and lung function. It is on a 0 (very poor health) to 100 (excellent health). Most physicians agree that a rating of 30 on this scale warning sign of serious health issues and a rating of 50 is acceptable health. This data is collected at the beginning of the study (Hratel) and at the end of the study (Hrate 2) Wellness rating (Wrate): Participants are asked to rate themselves in terms of how they are feeling health wise over the last week. This wellness rating is on a 0 (I feel terrible & am worried about my health) to 10 (I feel tremendous & I am in great shape). Physicians recognize that a rating of 3 or lower indicates that follow up measures should be taken and a rating of 6 or better indicates individuals have a positive sense of wellness.
