Objective: To summarize psychological longitudinal research (including population, method, and design characteristics) on family-related outcomes in Austria using a scoping review approach.Background: Evidence-based family policy and practice rely on country-specific research and evidence syntheses to aid in decision making. Longitudinal psychological research on family outcomes provides crucial information about families in a changing society, but an evidence synthesis for Austria is currently lacking.Method: Adhering to PRISMA guidelines, we searched five scientific databases (PsycInfo, PSYNDEX, Pubmed, Scopus, Web of Science) and conducted manual searches to identify additional grey literature. Ten sources (range sample sizes: 22 to 5,000) reporting on six data collection efforts between 1991 and 2015 were identified. Results were summarized narratively.Results: The majority of the samples consisted of heterosexual nuclear families, while research on more diverse family types is needed. Methods were primarily quantitative and conventional in design, but noteworthy exceptions exist. Comprehensive longitudinal data collection efforts across child development are lacking for the new millennium.Conclusion: State-of-the-art research implementing a triangulation of methods, designs, and perspectives that incorporates diverse family types using an intersectional approach is needed to draw accurate conclusions about the changing family landscape in Austria.
