To determine the extent to which movies popular with adolescents feature characters who jointly engage in violence and other risk behaviors. We hypothesized that violent characters engage in other risk behaviors equally often in films rated appropriate for children over 12 (PG-13) and Restricted (R)-rated films.
Content analysis of a sample of top-grossing movies from 1985 to 2010 (n = 390). We coded movies for the presence of at least 1 main character who was involved in violence and either sex, tobacco, or alcohol use within a 5-minute movie segment and throughout a film.
Approximately 90% of the movies contained a segment with a main character involved in violence, and ~77% of the films had the same character engaging in at least 1 other risk behavior. A violent character was portrayed most often partaking in alcohol-related and sexual behaviors. G and PG movies had less co-occurrence than PG-13 or R-rated movies, but there was no statistical difference between PG-13 and R-rated movies with regards to violence co-occurring with other risk behaviors. These trends did not vary over time.
Popular films that contain violent characters also show those characters engaging in other risk behaviors. Similar rates of co-occurrence between PG-13 and R-rated films suggest that the Motion Picture Association of America ratings system is not sensitive to the joint portrayal of violence and alcohol, sex, and tobacco-related risk behaviors. The on-screen clustering of violence with other risk behaviors is cause for concern and worthy of additional research.
确定青少年喜爱的电影中,共同表现暴力和其他风险行为的角色的程度。我们假设,在适合 12 岁以上儿童观看的 PG-13 级和限制级(R)电影中,暴力角色同样经常从事其他风险行为。
对 1985 年至 2010 年最卖座电影的样本进行内容分析(n=390)。我们对电影进行编码,以确定至少有 1 个主要角色在 5 分钟的电影片段和整部电影中参与暴力行为以及性行为、吸烟或饮酒行为。
约 90%的电影包含一个主要角色参与暴力的片段,约 77%的电影中同一个角色至少从事 1 种其他风险行为。暴力角色最常被描绘为参与与酒精相关和性行为。G 和 PG 级电影的共同发生频率低于 PG-13 或 R 级电影,但 PG-13 级和 R 级电影在暴力与其他风险行为共同发生方面没有统计学差异。这些趋势随着时间的推移没有变化。
包含暴力角色的流行电影也展示了这些角色从事其他风险行为。PG-13 级和 R 级电影之间相似的共同发生率表明,电影协会评级系统对暴力与酒精、性行为和烟草相关风险行为的共同描绘不敏感。屏幕上暴力与其他风险行为的聚类令人担忧,值得进一步研究。
