Sexual Ideals ------------- The data for the current analyses come from a dyadic study that was designed to determine if discrepancies in partners' sexual ideals were associated with relationship and sexual satisfaction, investments, quality of alternatives, commitment, sexual communication, and the perception that the relationship would dissolve in the future. To this end, members of N = 207 participating couples were each asked to indicate their own sexual ideals across a diverse set of 30 items (more information [here][1]). Differences in pornography use may reflect wider differences in personally held sexual ideals within relationships, in which case, controlling for differences in personally held sexual ideals may reduce or eliminate the associations between pornography use and sexual / relationship satisfaction that we have already established. ***Analyses:*** 1. The 30 sexual ideal items used in this study were purposely selected to represent a diverse range of sexual ideals, and thus, likely do not represent a unidimensional assessment of sexual ideals. To be used for our purposes, the 30 items will first be subjected to a Maximum likelihood Exploratory Factor Analysis with an oblique rotation. The number of factors that we will extract will depend on a consideration of a scree plot, parallel analysis, model fit, and conceptual interpretation. Factor scores will be computed for all retained factors. 2. A concordance-discordance variation of the actor-partner interdependence model predicting sexual / relationship satisfaction (e.g., Kenny, Kashy, & Cook,2006) will be applied to each of the dimensions that emerge in step (1). The basic model will include actors' factor scores on a dimension, their partners' factor scores on the same dimension, and the interaction between actors' and partners' scores. The resulting coefficients will be compared against the basic pattern that we have established for solitary pornography use, namely, a positive interaction term in the context of negative actor and / or partner effects. 3. To determine if similarity-dissimilarity in sexual ideals explains the effects of concordance-discordance in solitary pornography use, we will add the frequency of actors' solitary pornography use, the frequency of partners' solitary use, and their interaction, to each of the models outlined in (2). We will also consider a "grand" model that will simultaneously estimate all of the models outlined in (2) in addition the relevant predictors for solitary pornography use. [1]: https://osf.io/whz5p/
