The purpose of this study was to assess reports by psychologists and social workers in lawsuits regarding grandparent visitation rights in Barcelona (Spain). Seventy-three reports written during a five-year period were analysed Sixty-three per cent of cases recommended grandparents being granted visitation rights. A content analysis of the reports revealed that they were more likely to contain negative rather than positive comments about a family member (especially grandparents). Finally, the analysis showed that aspects such as grandparent abilities and a hidden agenda on the part of grandparents were associated with a recommendation that a visitation schedule be denied, whereas the presence of a strong bond between grandparents and the grandchild was related to a favourable recommendation. The article discusses directions for further research and the potential value of drawing up guidelines to assess grandparent rights in the event of family conflict.
