## **Participants** ## Data from approximately 128 couples was collected as part of a larger study on romantic relationships, ideals, and responsiveness. Participants were recruited by Qualtrics Panel, and both partners had to consent to participation to be included in the study. Additionally, all participants had to be able to speak and read English fluently, be at least 18 years or older, and must have been involved in a heterosexual romantic relationship of at least 4 months duration to be eligible to participate. ## **Procedures** ## Participation in this study occurred online, and involved anonymously and privately answering a number of questions regarding sexual ideals at two times (Part 1 and Part 2). Part 1 of this study began with a number of questions that gathered background information, then asked participants about their ideal sexual relationship and their perceptions of their partner’s ideal sexual relationship. Additional questions about communication, boredom, and participants' health were also included. After completing Part 1 of this study, participants were asked to complete Part 2 two weeks later. Part 2 consisted of questions about sexual ideals, communication, satisfaction, and health. For the purposes of the current study, only Part 1 data regarding participants' experiences of relational boredom, their perceptions of their partner's boredom, relationship quality, boredom coping strategies, and relationship security will be used. See the attached Instruments doc for the full measures used.
