Violent media content and aggressiveness in adolescents: A negative feedback-loop model

Discussion
Results of this study largely support the negative feedback-loop model for the
relationship of violent media content use and aggressiveness among adolescents. The
hierarchical tests of increment or decrement to the
2
fit statistic supported both
Hypotheses 1 and 2. In these data, prior aggressiveness predicted increases in use of
violent media content, consistent with a selective exposure perspective. Nonetheless, the
effect of prior violent media content use on increases in aggressiveness was significant
even after accounting for the selective exposure effects.
The individual path coefficients were also consistent with the proposed model
except for the time 1 to time 2 path from aggressiveness to violent media content use. In
other words, one can argue that in these data an indirect path exists from time 1 violent
media use to time 2 aggressiveness to time 3 violent media use, consistent with the
negative feedback-loop model. However, support is qualified by the fact that the
corresponding indirect path from time 1 aggressiveness to time 2 violent media use to
time 3 aggressiveness has one segment (the first) that did not reach statistical
significance. Support was therefore more consistent for the violent media content use to
aggression relation than for the reverse. It should be noted, though, that the stability path
between time 1 and time 2 media use was particularly high; the lack of effect of time 1
aggressiveness on time 2 use of violent media content might have been due to lack of
change in media use to predict.
