Longitudinal Study of Generations, California, 1971, 1985, 1988, 1991, 1994, 1997, 2000, 2005

The Longitudinal Study of Generations (LSOG), initiated in 1971, began as a survey of intergenerational relations among 300 three-generation California families with grandparents (then in their sixties), middle-aged parents (then in their early forties), and grandchildren (then aged 15 to 26). The study broadened in 1991 and now includes a fourth generation, the great-grandchildren of these same families. The LSOG, with a fully elaborated generation-sequential design, allows comparisons of sets of aging parents and children at the same stage of life but during different historical periods. These comparisons make possible the investigation of the effects of social change on inter-generational solidarity or conflict across 35 years and four generations, as well as the effects of social change on the ability of families to buffer stressful life transitions (e.g., aging, divorce and remarriage, higher female labor force participation, changes in work and the economy, and possible weakening of family norms of obligation), and the effects of social change on the transmission of values, resources, and behaviors across generations. The LSOG contains information on family structure, household composition, affectual solidarity and conflict, values, attitudes, behaviors, role importance, marital relationships, health and fitness, mental health and well-being, caregiving, leisure activities, and life events and concerns. Demographic variables include age, sex, income, employment status, marital status, socioeconomic history, education, religion, ethnicity, and military service.

《跨代纵向研究》（Longitudinal Study of Generations，简称LSOG），始于1971年，起初是对300个三代同堂的加利福尼亚家庭（其中祖父母当时六十余岁，中年父母当时四十初头，孙辈当时15至26岁）之间的跨代关系进行的一项调查。该研究在1991年得以拓展，如今已涵盖第四代，即上述家庭的曾孙辈。LSOG采用详尽的代际顺序设计，使得对处于相同生活阶段但在不同历史时期的老龄父母和子女群体进行比较成为可能。这些比较有助于研究35年间四代之间的社会变迁对代际团结或冲突的影响，以及社会变迁对家庭缓冲压力性生活转变（如老龄化、离婚再婚、女性劳动力参与度的提高、工作与经济的变化，以及家庭义务规范的潜在弱化）的能力的影响，以及社会变迁对价值、资源和行为在代际间传承的影响。LSOG包含了有关家庭结构、家庭组成、情感团结与冲突、价值观、态度、行为、角色重要性、婚姻关系、健康与体能、心理健康与福祉、照顾、休闲活动以及生活事件和关注点的信息。人口统计学变量包括年龄、性别、收入、就业状况、婚姻状况、社会经济历史、教育、宗教、种族和军事服务。数据集1（DS1 波次1-7）的代码手册长达5000余页；由于该文档篇幅庞大所引发的复杂问题，PDF内的搜索功能尚未启用。寻求特定变量的用户应使用PI代码手册内的搜索功能，或从研究页面使用变量搜索标签/选项进行搜索。
