Previous research in the field of gambling has contributed to understanding the etiology and phenomenology of gambling addiction, as well as potential interventions for individuals with gambling disorders. However, most studies have focused primarily on gamblers themselves. Significant others - partners, parents, children, and friends - have been largely overlooked in research, despite scientific evidence indicating a range of harmful psychosocial consequences they experience. Gambling-related harm is often hidden and difficult to quantify, and a major limitation of existing instruments lies in their insufficient differentiation by relationship type, which consequently limits their applicability in clinical practice. The aim of this project is to contribute to a more comprehensive scientific understanding of gambling-related harm among significant others, and to develop and validate specific self-assessment instruments - separately for parents and partners of individuals with gambling problems. Using a mixed-methods approach, the research will be conducted in four phases: (1) literature review and analysis of findings from a pilot project (quantitative methodology), (2) qualitative research (focus groups with significant others; N=24 participants), (3) construction and validation of self-assessment instruments (N≈200 participants), and (4) quantitative research on a national sample (N≈200) aimed at identifying gambling-related harms experienced by significant others as well as other relevant correlates. The key scientific contribution of this project lies in the development and validation of new self-assessment instruments for measuring gambling-related harm among significant others, specifically adapted to relationship type (parents or partners of individuals with gambling problems). This approach overcomes the limitations of currently available international instruments. Furthermore, the project has evidence-based practical implications, including the creation of guidelines for the application of these instruments in practice and the development of psychosocial interventions targeting significant others of individuals with gambling addiction.
