ABSTRACT
Despite this, individual TV viewing tends to be somewhat more stable in the beginning and in the end of the period studied - that is, in childhood and in young adulthood, respectively - than it is during adolescence. Comparing the two periods with equal intervals between measurements, the relative viewing level turns out to be most stable at the end of the age period, that is, between 19 and 21 years of age. This is only to be expected, both considering the fact that many habits are not really established before adulthood, and the fact that the most turbulent teenage period has now passed. The proportion of unexplained variance in TV viewing at the age of 21 is .59 and .57, respectively, indicating that between them, the three variables of earlier TV viewing, gender and social background are able to explain no less than about half the variation in TV viewing at this age.
