Please n one that good standards of peer reviewing constrain me JP to give you the original manuscript. I also had to anonymize identifying selective in get toation in the review. This review is meant as an example of the style used in writing a review you do not drive home to see all the details. Please note that this review is longer than the one you be requested to write.This is a highly interesting show on a timely subject, the impact of filth use in adolescence on birth conversance in early adulthood. Based on Zillmans programmatic bite active the influence of unrestrained dirty word on adolescents and to a greater extent late(a) search on teen daters use of internet pornography, the study develops a representative on how adolescent pornography use whitethorn affect human relationship intimacy in young adulthood. The study concludes that on that point is, at best, marginal support for Zillmanns cl aim that prolonged exposure to pornography is associated with f amiliar callousness (p. 13). The strengths of the study allow in, in my view, the focus on an under-enquiryed dependent protean its attempt to build and test a determine and the (attempted) investigation of versed activity disagreeences. The weaknesses include, in my view, the theoretical underdevelopment of the model and several severe methodological problems. metaphysical development of the modelBy the standards of Journal ANONYMIZED, the scheme section (pp. 2-4) is real numberly short. turn in journals of other disciplines (e.g., Journal of Adolescent Health) such(prenominal) a short introduction is requested, pieces in ANONYMIZED argon expected to be much specific astir(predicate) the theoretical underpinnings of the study. Although brevity is always preferable, a study that develops and tests a new model does require a somewhat more thorough c onceptual definition of the various influences in the model and, closely Copernicanly, a precept for these influences.Co nceptual definitions and rationale for the cistrons in the model The model has four components, exposure to pornography, pornographic reality, acceptance of amateur sex, and relationship intimacy. However, on p. 2, m each more suppositions are outlined (based on Zillmanns stem) habituation, finishing set up in monetary value of perceived knowledgeable behaviors, distrust in intimate partners, abandonment of exclusivity as a norm of romantic relationships, and greater endorsement of promiscuity. None of these concepts is tested. Moreover, on p. 3, several other concepts are mentioned, including distrustful attitudes close to love, sexual pleasure without affection, sexual callousness, and decreasing emotional attachment. age the latter concepts are related to what is tested, they are not the same. Scanning by dint of the studies that Zillmann and Bryant published in the 1980s, it expires clear that they have probably something else in chief when they talk about *sexual* callousness than an impaired ability to form intimate relationships (p. 4). Finally, it remains indecipherable why pornographic realism is an important addition to the model suggested by Zillmann. This is certainly not to say that the reports model is unrelated to Zillmanns ideas, only when the writing should aim for more conceptual clarity. Key concepts wishing to be defined. Moreover, it needs to be outlined how the rouge concepts of the model relate to Zillmanns ideas as well up as when and why they differ.Rationale for the influences hypothesized in the modelThe model hypothesizes that amateur attitudes toward sex mediate the effect of pornography on intimacy. Pornographic realism is included as a covariate of pornography use (although it is claimed that it is investigated as a mediator, p. 4). However, the rationale for hypothesizing these processes remains vague. First, how precisely are recreational attitudes related to sexual cordialization and the sexual script conc ept (p. 3)? How, and why, are these attitudes affected by pornography? These questions should not be answered on the basis of empirical regularities (as through with(p) on pp. 3-4), but on the basis of more elaborate theorizing. Second, why is pornographic realism a covariate (at least in the model tested)? From the citation on p. 4, it rather seems a mediator. This needs some clarification and elaboration, too. sexual urge differencesThe compend of gender differences occupies considerable space in the digest and discussion. However, a rationale is largely lacking why such differences need to be investigated. There is sufficient evidence that females use pornography less practically than males do (i.e., gender as a direct predictor), but it is essential to outline why the processes hypothesized may differ by gender (i.e., gender as a moderator).Methodological problemsI would like to stress that any research on the issue of the study is admirable, given the enormous ethical, p ractical, methodological, statistical issues involved. In my evaluation, I take this into account. That said, I do have to grind away some potentially unpleasant questions about the design of the study operationalization of the key card procedure/ sample and analysis.Design and operationalization of key measureThe paper aims at testing a causative model, but relies on cross-sectional data. The paper outlines on p. 4 that the study includes a time component by asking respondents to indicate their pornography use at long times 14 and 17. Several problems arise. First, cross-sectional data do not permit causal conclusions related to media effects. At the very least, this needs to be acknowledged explicitly and prominently. Also, language suggesting causal relations should be avoided. Second, asking respondents retrospectively about their pornography use at the ages of 14 and 17 raises some questions. why at ages 14 and 17? Adolescence usually spans the period between age 12 and 17 . Why was exposure not measured, for instance, for age 12 (early adolescence), age 15 (middle), and age 17 (late)? Third, self-reported retrospective measures of sensitive behavior are prone to multiple biases, most notably memory bias and social desirability bias.These biases already plague measures that relate, for instance, to the past week. But how can such measures meaningfully be applied to behavior that happened, for the oldest respondents, 11 years agone? Fourth, what exactly were the solvent categories? Never suggests a vague-quantifier shell (e.g., neer, rarely,sometimes, often, very often), which carries a lot of problems, most notably the problem that vague quantifiers leave it up to the respondent to decide what the categories mean. However, the positive anchor of the scale is every day. Was the scale thus a scale asking about specific frequencies (e.g., once a week, less than once a week). Again, how can such frequencies be assessed validly after so much time? Any teaching on the validity and reliability of the measure along with a rationale for the operationalization is highly welcome.Fifth, how does this measurement strategy assess prolonged exposure, the key concept in Zillmanns paper? Assessing retrospectively the use of pornography does not tell us much about the trajectory of porn use. Finally, a retrospective measure is not the same as a measure taken at a certain point in the past, in contrast to what is claimed on p. 4. I perfectly understand that longitudinal research is cumbersome, particularly in that area. That said, it seems difficult to see how the retrospective measurement of pornography use tackles the causal problems inherent in cross-sectional research. In sum, there are several serious issues with the operationalization of one of the key variables, which urgently need to be addressed.Procedure/ SampleThe paper is unfortunately very design about the procedure and sample of the look back. Given the self-selection problems in sex research, I was surprised to read that few precautions were taken to minimize this bias. Why was snowballing not avoided, but even encouraged (p. 5)? Why did the study not include some simple quotas, most notably for gender (see below)? Was there a control of whether a particular respondent filled in the survey multiple times? In addition, I assume that informed approve was explicitly asked for, but this should be mentioned briefly. Finally, is there an indication of how many respondents were contacted and what the response rate was? There are also several important questions about the sample. First, why was the study limited to sexually active students? Sexual hold out may create a limiting boundary condition for what the paper is interested in.Second, why was the age frame limited to 18- to 25-year olds? Is this related to the theory of emerging adulthood? Third, why was the study limited to university students? We complain about such convenience samples in experimental r esearch. Theremay be even more concerns about such samples in survey research. While the concerns raised in the previous paragraphs address very severe defects, they may even be multiplied by the fact that twice as many women as men filled in the questionnaire. This is a essential problem because the basic conclusion of the paper is that the model only whole works for women, but not for men. To be sure, the paper mentions these shortcomings in the discussion section, but that does unfortunately not reduce its importance.Table 2 shows small to reclaim zero- dress correlations for men and women. However, with twice as many women as men in the sample, an r = -.11 is significant for women, while an r = .13 is not significant for men. two for men and women, the correlations are in the same direction. I guess that, with an embody number of men and women (e.g., 350 each), the model would largely hold for both. This would also be a more reasonable sample size in terms of statistical po wer consideration. In conclusion, there is reason to believe that one of the main conclusions of the paper is a result of a severe shortcoming in the sample procedure of the study.AnalysisThe general problems with the gender analysis notwithstanding, I was wondering why the paper does not apply a multiple-group analysis. This is a more rigorous way of testing whether the various paths differ between women and men than the strategy currently employed. I was wondering whether the SEM analysis used item-parceling strategies. Otherwise, there need to be more manifest indicators in the models. Finally, the statistical testing of indirect effects (i.e., whether they differ significantly from zero) has become a standard procedure and should be included. DiscussionIn the unprovoked of the problems raised above, some of the conclusions raised in the discussion section may need some reconsideration. (This is my opinion, and the authors may or may not bring home the bacon them). First, I am hesitant to agree with the paper that the findings have miniscule if any practical significance (p. 10). The discussions about effect sizes in media effects research in particular and the social sciences in general have been outlined elsewhere and do not have to be perennial here. Against that backdrop, an explained variance of 8% (with two predictor variables related to pornography) inrecreational attitudes and of 16% in relationship intimacy does not seem useless to me. It may indeed be that other variables (family, peers etc.) have a greater influence, but this needs some more backing in order to contextualize the effects found.I agree with the paper that the moral panic that surrounds pornography finds no support in any research published so far. However, this does not mean that the effects found in this paper and elsewhere are trivial, at least when considered in the context of media effects research and against the backdrop of the methodological and statistical problems tha t this kind of research faces. Second, it seems to me that the paper contradicts itself when, on the one hand, it rejects main effects as too simplistic (p. 3) and, on the other hand, describes the found indirect effects as practically insignificant. No serious media effects researcher would disagree that media effects are typically not direct and that a focus on the how and why of such effects is important. If we can explain how precisely media affect populate, then this may have enormous practical significance, especially if we can outline which people may be affected and which may not (in line with Malamuths ideas).Third, I agree that love maps and sexual scripts may explain sexual attitudes and behavior, probably even better than media use (p. 11). But it remains unclear to me where, precisely, this is tested in the model. Some clarification may be helpful. Fourth, it may also be helpful to specify how the distinction between imagined and real sex lives relates to the model tes ted, apart from outlining that perceptions of pornographic realism may never fully translate into peoples actual sex lives.In sum, this is important and interesting research. However, the theoretical, conceptual, and methodological weaknesses currently outweigh the strengths of the paper so that its contribution to our knowledge about how the use of pornography affects relationship intimacy in adulthood is limited.
