Development and Validation of a Measure of the Resolution Phase of the Sexual Response Cycle: The Sexual Resolution Scale (SRS).

We developed and validated a measure of the depth of the resolution experience - the Sexual Resolution Scale (SRS). Portuguese-speaking participants responded to an online survey including the SRS whose eight items were derived from the literature on post-sex states: 1) deeply relaxed, 2) with elevated heart rate, 3) with intensified emotions, 4) more aware of body, 5) in a profound peace, 6) more imaginative, 7) more predisposed to talk about emotionally charged topics, 8) more predisposed to listen to emotionally charged topics. They also reported the intensity of satisfaction, desire, arousal, and orgasm, during the last sexual activity, and completed the Perceived Relationship Quality Components Inventory, and the Female Sexual Function Index or the International Index of Erectile Function. Principal Component Analysis and Confirmatory Factor Analysis revealed two dimensions: Internal Experience (items 1 to 6) and Openness to Communication (items 7 and 8). The two dimensions had good reliability. Invariance was confirmed between women and men. Nomological validity evidence was demonstrated: the two dimensions correlated with better sexual function during the last sexual activity and over the past 4 weeks. The SRS appears to be usable to measure the enjoyable aspects of the resolution phase of sexual intercourse.
