The aim of the current study is to describe and explore basic family relations, parental bonding, and dyadic adjustment in families with offspring diagnosed with a psychotic disorder. The sample was made up of 120 participants, 60 in the clinical group (GCL) and 60 in the comparison group (GCP). All participants were assessed using the Basic Family Relations Evaluation Questionnaire (CERFB), the Parental Bonding Instrument (PBI), and the Dyadic Adjustment Scale (DAS). The results showed differences between the clinical and comparison groups in terms of perceptions of basic family relations, dyadic adjustment and parental bonding. The clinical group recorded less favorable results for all of these variables. More specifically, the study observed significant differences between the groups in parental function, overprotection and caring. This study deepens our understanding of how family assessment and relational diagnoses can serve as prevention and intervention tools for families affected by a psychotic disorder.
