Pornography Consumption

Pornography is generally defined here as Playboy, Penthouse and Hustler magazines.
Subjects indicated on a 5-point scale ranging from “never” to “every issue” how often
they read from a list of 15 magazines, 11 of which were general interest magazines, 4
of which were the sexually explicit magazines mentioned above. Malamuth, Addison
& Koss (2000) recommend that a general operational definition of pornography is
best to avoid issues of interpretation by the subject and the experimenter, and
demand-effects based on what the experimenter thinks pornography does or does not
do. Furthermore, the concrete and objective operational definition of the scale’s
maximum level as “every issue” was a refinement over the subjective wording used
in (Malamuth, Addison & Koss, 2000), which indicated the maximum based on the
subjects perception of “very frequently.”
Sexual Aggression

Sexual Experiences Survey for Males, (SES). 10 items. The “perpetrator” version of
this questionnaire (Koss & Dinero, 1988; Koss & Gidycz, 1985; Koss & Oros, 1982)
asks male participants to report whether they have engaged in various sexual
behaviors; specifically, it asks males to report their history of sexual aggression,
including coercive and assaultive sexual behaviors legally within the definition of
rape. Participants in this study were asked how many times they had engaged in each
act, and responded on a five point scale ranging from “0 times” to “more than 4
times.” This response format differs from the original dichotomous format used in
Malamuth et al. 1995, and was intended to yield more sensitive differentiation in the
range of sexual aggression. Participants’ histories of sexual aggression (including
sexual coercion and sexual assault) were calculated as a total frequency score.

Statistical Procedures

Structural equation modeling was used for its combination of aspects of both “factor
analysis” and “path analysis.” For example, SEM enabled us to ‘capture’ the shared
variance within the facets of the “General Hostility” construct (irritability, low-empathy,
negative masculinity). Structural equation modeling also enabled us to fully explore the
mediation effects between factors and the dependent variable of sexual aggression.
Finally, the relationship among higher order factors could be included in the model and
organized within a hierarchical framework. The degree to which the level of organization
used was appropriate or not was indicated by statistical tests.
