Development and validation of a measure of sexual motivation

该项目的主要目标是制定和验证一套评估性动机的措施。所采用的测量方法是植根于激励理论帐户的性动机，强调的潜力，性刺激激活一个中央的动机状态，旨在获得性满足。它是基于有效性的概念，需要一个属性的因果关系的影响，其措施和成功应用这一原则在动机科学的基础上分析想象力的图片故事的证据。该项目的具体目标是：（1）在内容编码和自动文本分析的基础上，开发性需求图片故事测量方法;（2）开发一套适当的图片，用于引出故事;（3）确定nSex测量的（编码器间、重测、图片/响应曲线）;（4）测试nSex测量对动机核心现象的预测有效性（注意力，情感，心理生理学和激素，联想学习，工具学习/行为，日常生活中的性活动频率及其与情感幸福感的关系）;（5）检验其收敛效度和判别效度。研究1的结果表明，色情刺激的启动会导致图片故事中表达的动机意象发生明显变化。在该项目的第一阶段，三个实验性唤醒程序-启动，电影和录音-将用于唤醒的方法和避免方面的性动机（研究2-6）。它对故事内容的影响，客观和主观的影响措施，和生理措施将被检查。在确定所有研究中一致出现的图像和标记词后，由此产生的内容编码和文本分析工具将用于该项目的第二阶段，该项目使用图片故事nSex措施来评估性动机的倾向方面。研究7将使用眼动追踪来检查nSex和对色情刺激的注意定向之间的关联。研究8将探讨中性刺激和色情刺激之间的关联的形成中的nSex的作用。研究9着眼于nSex的作用，在行为偏好的色情刺激和内隐学习的刺激-反应序列的差异加强色情刺激。研究10是一项纵向设计（1个月）的实地研究，其中参与者被给予两次图片故事nSex测量（女性：一次在卵泡期，一次在黄体期），提供三份唾液样本用于评估性腺类固醇，并每两天报告一次他们的情绪健康和性活动。新的nSex措施的收敛性和判别效度将通过与性动机的自我报告措施，人格特质的措施和其他动机的内容编码措施进行比较来确定。

The main goal of this project is the development and validation of a set of measures for the assessment of sexual motivation. The measurement approach employed is rooted in incentive-theory accounts of sexual motivation that emphasize the potency of sexual incentives for activating a central motive state aimed at obtaining sexual satisfaction. It is based on a concept of validity that requires evidence for a causal effect of an attribute on its measure and successful applications of this principle in motivation science based on the analysis of imaginative picture stories. The specific objectives of the project are: (1) Development of picture-story measures of the need for sex (nSex) based on content-coding and automated text analysis; (2) development of a suitable picture set for eliciting stories; (3) determination of the reliability (inter-coder, retest, picture/response profile) of the nSex measures; (4) testing the predictive validity of the nSex measures for core phenomena of motivation (attention, affect, psychophysiology and hormones, associative learning, instrumental learning/behavior, frequency of sexual activity in daily life and its association with emotional well-being); (5) examining its convergent and discriminant validity. Findings from a pilot experiment (Study 1) show that priming with erotic stimuli leads to distinct changes in motivational imagery expressed in picture stories. In a first phase of the project, three experimental arousal procedures - priming, movies, and audio recordings - will be used for the arousal of approach and avoidance aspects of sexual motivation (Studies 2-6). Its effects on story content, objective and subjective measures of affect, and measures of physiology will be examined. After identifying imagery and marker words that emerge consistently across all studies, the resulting content-coding and text analysis tools will be used in the second phase of the project, which uses picture-story nSex measures to assess dispositional aspects of sexual motivation. Study 7 will use eye tracking to examine the association between nSex and attentional orienting to erotic stimuli. Study 8 will examine the role of nSex in the forming of associations between neutral stimuli and erotic stimuli. Study 9 looks at the role of nSex in behavioral preferences for erotic stimuli and implicit learning of stimulus-response sequences differentially reinforced by erotic stimuli. Study 10 is a field study with a longitudinal design (1 month) in which participants are administered the picture-story nSex measures twice (women: once in follicular, once in luteal phase), provide three saliva samples for the assessment of gonadal steroids, and report every two days on their emotional well-being and sexual activity. Convergent and discriminant validity of the new nSex measures will be determined via comparison to self-report measures of sexual motivation, measures of personality traits, and content-coding measures of other motives.
