The work–family interface can be viewed as a process in which daily fluctuations in work demands and resources influence family functioning and behavior, and vice versa. This study aimed to test the daily processes of both directions of the work–family interface through two studies. The first study consisted of 103 male and female workers from 17 Brazilian states. The participants’ ages ranged from 20 to 61 years (M = 33.68; SD = 9.13). Each participant answered a daily questionnaire over the course of 10 days, totaling 1,030 answers. The second study’s sample consisted of 101 male and female workers from 15 states in Brazil. Participants’ ages ranged from 20 to 62 years (M = 33.77; SD = 8.46). Each participant answered the daily questionnaire over the course of ten days, with the number of answers totaling 1,010. The first study showed that at the daily level, perceived work-related demands and social support at work were significantly related to family satisfaction. The second study indicated that at the daily level, perceived family demands and family social support showed significant associations with job satisfaction. Positive affect had a mediating role in these relationships, whereas the use of problem-solving coping strategies had a moderating role. Both studies also showed that the relationships identified remain significant when the variables were tested at different times: independent variables, mediating variable and moderator variable on one day, and the dependent variable on the following day. Day-to-day implications for organizations are discussed, and suggestions for a future research agenda on the work–family interface are presented.

测试工作家庭界面的两个方向：日记研究

工作-家庭界面可以看作是工作需求和资源的日常波动影响家庭功能和行为的过程，反之亦然。本研究旨在通过两项研究测试工作-家庭界面两个方向的日常过程。第一项研究由来自巴西 17 个州的 103 名男性和女性工人组成。参与者的年龄从 20 岁到 61 岁不等（米= 33.68;标清= 9.13)。每个参与者在 10 天内回答了一份每日问卷，总共有 1,030 个答案。第二项研究的样本包括来自巴西 15 个州的 101 名男性和女性工人。参与者的年龄从 20 岁到 62 岁不等（米= 33.77;标清= 8.46）。每位参与者在十天的时间里回答了每日问卷，答案总数为 1,010。第一项研究表明，在日常层面，感知到的工作相关需求和工作中的社会支持与家庭满意度显着相关。第二项研究表明，在日常层面，感知到的家庭需求和家庭社会支持与工作满意度有显着关联。积极情绪在这些关系中起中介作用，而使用解决问题的应对策略起调节作用。两项研究还表明，当变量在不同时间进行测试时，所确定的关系仍然显着：第一天是自变量、中介变量和调节变量，第二天是因变量。
