We used a mixed-method design to examine the attributions women in mixed-gender/sex relationships make for their partner's perceived pornography use and whether such attributions covary with women's relationship and sexual satisfaction. A final sample of 199 women completed measures of relationship satisfaction, sexual satisfaction, and their perceptions of partner's pornography use. Participants also completed three open-ended questions assessing their attributions of their partner's perceived pornography use. Qualitative analyses revealed 11 themes in women's attributions of their partner's perceived pornography use; some of the themes reflected on women themselves (e.g., being open-minded and accepting), whereas other themes reflected on the partner (e.g., partner is sexually bored) or the relationship (e.g., strong and trusting relationship). Furthermore, the women made positive, negative, and neutral attributions. Quantitative analyses showed that positive attributions were significantly more frequent than neutral or negative attributions and the latter two categories did not differ significantly from each other. Also, greater frequency of positive and neutral attributions and lower frequency of negative attributions were associated with higher relationship satisfaction and sexual satisfaction. Our results suggest that women make a range of attributions about their partner's pornography use and that this variation relates meaningfully to indices of relationship functioning.
