Comment on: Is Pornography Use Associated with Sexual
Difficulties and Dysfunctions among Younger Heterosexual Men?
Surprisingly, given its potential clinical relevance,
very few studies have attempted to investigate rela-
tionships between pornography consumption and
common sexual dysfunctions and problems (in
the following referred to as “sexual difficulties”).
When having done so, the designs employed have
predominantly been case study designs or focus
group designs and the method of data collection
qualitative. Alternatively, personal or clinical expe-
riences have been utilized. Although important,
such studies and experience alone may not be
brought to bear on effects of the consumption
of pornography. Consequently, the study by
Landripet and Stulhofer offers a long and valuable
cross-cultural beginning to the quantitative explo-
ration of associations between pornography con-
sumption and sexual difficulties.
More generally, elements of the study by
Landripet and Stulhofer reflect critical issues in
research on pornography. First, the sample most
likely constitutes a non-probability sample. This is
characteristic of much of the available research on
pornography today [1]. This problem may some-
what be offset by including short, valid, and reli-
able measures of pornography consumption in
future large population based national studies on
sexuality and sexual behaviors. Considering the
prevalence rates of pornography consumption and
the frequency by which pornography is consumed,
in particular among men, this seems both highly
relevant and high time.
Second, the study finds only one significant
association between pornography consumption
and the outcomes studied (i.e., erectile dysfunc-
tion) and emphasizes that the size (magnitude) of
this relationship is small. However, in pornogra-
phy research, the interpretation of “size” may
depend as much on the nature of the outcome
studied as the magnitude of the relationship found.
Accordingly, if the outcome is to be considered
“sufficiently adverse” (e.g., sexual aggressive
behaviors), even small effect sizes may carry con-
siderable social and practical significance [2].
Third, the study does not address possible mod-
erators or mediators of the relationships studied
nor is it able to determine causality. Increasingly,
in research on pornography, attention is given to
factors that may influence the magnitude or direc-
tion of the relationships studied (i.e., moderators)
as well as the pathways through which such influ-
ence may come about (i.e., mediators) [1,3]. Future
studies on pornography consumption and sexual
difficulties may also benefit from an inclusion of
such focuses.
Fourth, in their concluding statement, the
authors suggest that a number of factors are more
likely related to sexual difficulties than pornogra-
phy consumption. To better assess this, as well as
the relative contribution of each of these variables,
the use of comprehensive models able to encom-
pass both direct and indirect relationships between
variables known or hypothesized to influence the
outcome may be advised [3].
Overall, the study by Landripet and Stulhofer
provides first and an interesting cross-cultural and
quantitative insights into possible associations
between pornography consumption and sexual dif-
ficulties. Hopefully comparable future studies may
use this as a stepping stone to further advance the
research on relationships between pornography
consumption and sexual difficulties among both
men and women.
