ABSTRACT
To assess motivations associated with sexual intimacy, a need for sexual intimacy scale (NSIS) was developed within a needs-based framework, focusing on needs for sex, affiliation, and dominance. Participants were 347 individuals associated with two large Southern California universities. Both exploratory and confirmatory factor analyses (EFA and CFA) were utilized, as were multiple attitudinal and behavioral measures for validation purposes. EFA found 22 items to be associated with the three need sets, with good internal consistency reliability. CFA confirmed these findings, and promising construct and criterion validities were also noted for the factors. Those reporting a greater need for sex noted more lifetime sex partners and one-night stands, but were less likely to use condoms. Individuals with affiliation needs were more likely to be truthful with their partners and more likely to practice safe-sex. Those reporting dominance needs want to control their partners sexually, but were less likely to use condoms. Men were found to exhibit greater needs for sex, while women reported higher levels of affiliation need. Sexual health and primary prevention concerns are discussed.
Notes
1CFA Model 2 (modified model) with one cross-loading and nine within factor error covariations: Need for Sex (Item 1 with 3; 2 with 5,6); Need for Affiliation (Item 1 with 3, 5, 6; 7 with 9); Need for Dominance (Item 1 with 2, 3).
2CFA results forced a 3-factor solution with items allowed to load only on the factor suggested by EFA (unless otherwise noted).
3Item also crossloads .38 on Need for Sex.
