This paper presents a novel psychological model of the socio-cognitive management of uncertainty, the semiotic dimensional model (SDM). The SDM claims that uncertainty increases the momentum of affect-laden meanings in meaning-making. This is so because affective meanings provide a simplified interpretation of the world that restores the experience of being able to make sense of the reality destabilized by uncertainty. Moreover, the SDM models the affective meanings in terms of low-dimensional mental phase space (MPS). Each dimension of the MPS detects a facet of the context. The lower the MPS dimensionality, the lower the number of facets of the context processed, therefore, the more simplified the meaning-making is. We attained the first empirical validation of the SDM in a sample of 120 Italian people. First, the SDM assumption that the low-dimensional MPS is the computational descriptor of affective meaning was tested. Second, an experimental study was designed in which uncertainty was manipulated so as to assess its effects on the dimensionality of participants' MPS. It was hypothesized that uncertainty induces a decrease in the MPS dimensionality. Results were consistent with both hypotheses. Theoretical implications of the SDM and its relationship with other theories are discussed and future research direction outlined. [ABSTRACT FROM AUTHOR]

When people receive a diagnosis of chronic or non-communicable disease, they need to reorganize their lives to understand and accommodate the changes associated with the new health condition. This reorganization, which involves the activation of a process through which meaning is given to the illness, could be fostered by narrative methods also in the context of Primary Care. The Sense of Grip on Disease (SoGoD) model intends to focus on the role of sense-meaning-making processes in the psychological adjustment to non-communicable illness, emphasizing the patients' role in managing their own health condition. In this study, the authors propose a mixed-method research method which implies the adaptation of the narrative interview on the Sense of Grip on Disease. The interview was administered to 31 adults suffering from non-communicable diseases and has been analyzed with a theory-driven approach, which aims to explore the modalities of five narrative functions: organization of temporality, integration of illness, expression of emotions, social sharing and orientation to action. Through a Multiple Correspondence Analysis and a Cluster Analysis, the authors have identified two different 'Grip Profiles', called "Dynamic Profile" and "Compliant Profile", representative of different degrees of flexibility, integration and adjustment to disease.
