Santos-Iglesias 1 , S.E. Byers 21 University of Granada, Granada, Spain, 2 University of New Brunswick,Fredericton, NB, CanadaSexual satisfaction is determined by sexual communication, howeveronly the role of sexual self-disclosure has been tested. Other forms ofsexual communication such as sexual assertiveness or nonverbal sexualcommunication have never been tested before. The aim of the presentstudy is to analyze the extent to which sexual satisfaction in couples isindividually and uniquely related to various forms of sexual communication,such as verbal and nonverbal communication and sexual andnonsexual self-discolsure. And also to test whether there is an instrumentalpathway between each of these forms of sexual communicationand sexual satisfaction in both male and female partners. One hundredcouples will be surveyed online from both a Canadian and a Spanishuniversity to collect data on sexual and nonsexual self-disclosure,verbal and nonverbal sexual communication, as well as sexual satisfactionaccording to the instrumental pathway. Results will provide evidencefor the contribution of different forms of sexual communicationover and above sexual self-disclosure to couples’ sexual satisfaction andhow these forms contribute to the components of the instrumentalpathway. Also they will allow to compare Canadian and Spanishsamples and to analyze cross-cultural differences. Results will alsoprovide valuable information for therapeutical interventions.91TURNING SEXY THOUGHTS INTO SEXYBEHAVIOURS: HETEROSEXUAL DATERS’SEXUAL INITIATION BEHAVIOURSD.C. Simms, S. ByersPsychology, University of New Brunswick, Fredericton, NB, CanadaIntroduction: Sexual initiation behaviours contribute to sexual satisfactionin long-term couples (Byers & Heinlein, 1989). To explore thisrelationship in short-term daters, the current study used the Theoryof Planned Behaviour (Ajzen, 1992) to investigate daters’ sexual initiationbehaviors, and their association with sexual satisfaction.Method: Participants were 151 young adults (75% female; M = 20.9years) in heterosexual dating relationships. All completed an onlinesurvey.Results: Compared to women, men initiated more frequently, hadstronger sexual initiation intentions, and perceived more positive socialnorms regarding initiation. However, the men and women did notdiffer in their attitudes towards initiating or perceptions of their competenceto initiate. Finally, more frequent sexual initiations were associatedwith greater sexual satisfaction for both men and women.Discussion: While cognitive aspects of the initiation script are egalitarian,initiation behaviors are guided by gender-discrepant sociosexualnorms. Additionally, initiation behaviors are associated with sexualsatisfaction within dating relationships.92DEFINITION OF SEXUAL SATISFACTION,A QUALITATIVE ANALYSIS OF ON-LINERESPONDENTS IN COHABITATION: THEROLE OF GENDER, SEXUAL ORIENTATION,RELIGION AND SEXUAL PROBLEMSP. Pascoal 1 , I. Narciso 1 , N.M. Pereira 21 Faculdade de Psicologia, Universidade de Lisboa, Lisboa, 2 Departamento deCiências da Saúde, Universidade Lusofona de Ciências e Tecnologias, Lisbon,PortugalObjective: Definitions of sexual satisfaction have been derived fromtheory or research-driven conceptual definitions, but little is knownabout how people in relationships conceptualize sexual satisfaction forthemselves, using their own words. Our goal was to assess differencesin personal definitions of sexual satisfaction associated with gender,sexual orientation, and the presence of sexual problems.Method: Participants were 973 individuals (59% women and 41%men) living with a partner who completed an on-line survey.Results: Thematic analysis using NVivo indicated that two majorthemes: one related to pleasure and one related to relationship andintimacy. It also identified some subthemes. There were some differencesin definitions based on whether individuals identified as male orfemale, were in a mixed-sex or same-sex relationship, and had or hadnot sexual problems.Discussion: The results are used to highlight the strength and problemsassociated with existing definitions and measures of sexualsatisfaction.93SYMPOSIUM TITLE: GID AND BRAINFUNCTION: INTRODUCTION ANDOVERVIEW OF CURRENT RESEARCH IN GIDG.
