The mean of the number of hours played per week was 21.9, and the median was 20. Players under the age of 23 tend to play about 2 hours more each week than players over 22 (23.2 -vs- 21.2, p = .01, significant, but a trivial difference with this sample size). There were no gender differences.
A multiple regression analysis using age, gender, motivations and personality traits revealed that the motivation to socialize and find group affiliation were the best predictors of hours of play per week. Even though the contribution coefficients seem small, for comparison note that between the lowest and highest scoring players on the Social motivation is a difference of about 8.5 hours played per week (from 17.1 to 25.5 hours).
Is there a correlation between hours per week played and how often a player groups with people they've played with before? I find personally that if I play less than 10 hours a week (at random times) I almost always have to group with strangers since most of the people I played with before are offline or have leveled way past me.
Indeed. The main reason I play so often is so that I can keep up with the others in my guild and those I befriend in the early days. Also so that I can get to a higher level to help out my guild-mates especially.
It is scary to think that some play for 40 or more hours per week without relising that they are 'addicted'. Although only 7.9% of people fit into this catagory that turns into about 10.6 million people in the US alone. I am basing my calculations on another paper which states that roughly half of all americans play video games at least once a day.
Is there any correlation to hours of gameplay and eccentricities in behavior?
I likely play approximately 20 hours per week on average. To Josh, would a person who read books or watched TV for 40 hours a week be addicted? Is 10-15 hours of each activity better than 40 hours of just 1?
I think there is a percentage of people who might stay on longer due to an addiction, but far more because it's the most entertaining thing they have available to them. An activity is considered an addiction when it starts to interfere with other life activities such as work, social interaction, etc.
