Longitudinal psychological research on family outcomes provides crucial information about families in a changing society, but an evidence synthesis for Austria is currently lacking. Therefore, we aim to summarize psychological longitudinal research on family-related outcomes in Austria using a scoping review approach. Adhering to PRISMA guidelines, we searched five scientific databases (PsycInfo, PSYNDEX, Pubmed, Scopus, and Web of Science) and conducted manual searches to identify additional grey literature. Ten sources reporting on six data collection efforts between 1991 and 2015 were identified. Most samples consisted of heterosexual nuclear families, while research on more diverse family types is needed. Methods were primarily quantitative with conventional designs, but noteworthy exceptions exist. Comprehensive longitudinal data collection efforts across child development are lacking for the new millennium. State-of-the-art research implementing a triangulation of methods, designs, and perspectives that incorporate diverse family types is needed to draw accurate conclusions about the changing family landscape in Austria.
