This research examined the association between a novel measure of perceived partner availability and discordance between ideal and actual partner characteristics as well as trajectories of ideal partner preferences and perceptions of partner availability over time.
A clinic-recruited cohort of adolescent females (N = 92), aged 1619 years, were interviewed quarterly for 12 months using audio computer-assisted self-interview. Participants ranked the importance of characteristics for their ideal main sex partner and then reported on these characteristics for their current main partner. Participants reported on perceptions of availability of ideal sex partners in their neighborhood. Paired t-tests examined discordance between ideal and actual partner characteristics. Random-intercept regression models examined repeated measures.
Actual partner ratings were lower than ideal partner preferences for fidelity, equaled ideal preferences for emotional support and exceeded ideal preferences for social/economic status and physical attractiveness. Discordance on emotional support and social/economic status was associated with sex partner concurrency. Participants perceived low availability of ideal sex partners. Those who perceived more availability were less likely to be ideal/actual discordant on fidelity [OR = .88, 95% CI: .78, 1.0]. Neither ideal partner preferences nor perceptions of partner availability changed over 12 months.
Current main sex partners met or exceeded ideal partner preferences in all domains except fidelity. If emotional needs are met, adolescents may tolerate partner concurrency in areas of limited partner pools. Urban adolescent females who perceive low availability may be at increased risk for sexually transmitted infection (STI) because they may be more likely to have nonmonogamous partners.
本研究探讨了一种新的感知伴侣可得性的测量方法与理想伴侣特征和实际伴侣特征之间的不一致性，以及理想伴侣偏好和伴侣可得性感知随时间的变化轨迹。
从诊所招募了一组年龄在16至19岁之间的青春期女性（N = 92），通过音频计算机辅助自我访谈，每季度进行一次为期12个月的访谈。参与者对理想主要性伴侣的特征重要性进行排序，然后报告其当前主要伴侣的这些特征。参与者报告了对邻里中理想性伴侣可得性的感知。配对t检验用于检验理想伴侣特征与实际伴侣特征之间的不一致性。随机截距回归模型用于检验重复测量数据。
实际伴侣在忠诚方面的评分低于理想伴侣偏好，在情感支持方面与理想偏好相当，在社会/经济地位和身体吸引力方面超过理想偏好。情感支持和社会/经济地位方面的不一致与性伴侣并发有关。参与者认为理想性伴侣的可得性较低。那些认为可得性较高的人在忠诚方面出现理想/实际不一致的可能性较小[比值比 = 0.88，95%置信区间：0.78，1.0]。在12个月内，理想伴侣偏好和伴侣可得性感知均未发生变化。
当前的主要性伴侣在除忠诚之外的所有领域都达到或超过了理想伴侣偏好。如果情感需求得到满足，青少年可能会在伴侣资源有限的领域容忍伴侣并发。认为可得性较低的城市青春期女性可能感染性传播感染（STI）的风险增加，因为她们可能更有可能拥有非一夫一妻制的伴侣。
