Family planning study 1

Because prior parenting experiences (e.g., parity, the sex of current children) often change individuals’ fertility intentions (Balbo, Billari, &amp; Mills, 2013), this work focused exclusively on fertility decision-making practices of childless individuals. The sample was also limited to individuals of reproductively viable age; defined as ages 18-45 (see Toulemon &amp; Testa, 2005). The current work obtained an internet-based sample of 241 participants, with an average age of 22 years (<i>SD</i> = 5.33), through both general population and university sources (Mechanical Turk, N = 80; SONA [university students], N = 55; Reddit, N = 106). All participation was via Qualtrics software. Thirty-five participants indicated that they were parents and were therefore excluded from further analysis (resulting in N = 206). Mechanical Turk participants were compensated 25 cents for their participation, SONA participants were enrolled in a large Midwestern University and compensated with course credit for their participation, and Reddit participants did not receive any compensation for their participation. The current sample was predominantly female (59.7%), White/Non-Hispanic (80.6%), heterosexual (87.4%), and involved in a romantic relationship (46.6%).

由于既往育儿经历（如生育胎次、现有子女的性别）通常会改变个体的生育意愿（Balbo、Billari与Mills，2013），本研究仅聚焦于无子女个体的生育决策行为。本研究的样本同时限定于生育适龄期个体，即年龄介于18至45岁之间（参见Toulemon与Testa，2005）。本研究通过大众渠道与高校招募渠道（机械Turk（Mechanical Turk）：N=80；SONA[高校学生渠道]：N=55；红迪（Reddit）：N=106）招募了241名线上参与者，其平均年龄为22岁（标准差（SD）=5.33），所有参与流程均通过Qualtrics软件完成。其中35名参与者自述为人父母，因此被排除在后续分析之外，最终有效样本量为206。机械Turk参与者可获得25美分的参与报酬，SONA渠道的参与者来自美国中西部某大型高校，可获得课程学分作为参与奖励，而红迪渠道的参与者未获得任何形式的报酬。本研究样本以女性为主（占比59.7%），白人/非西班牙裔群体占比80.6%，异性恋群体占比87.4%，且有46.6%的参与者处于恋爱关系中。
