Borderline Intellectual Functioning: Consensus and good practice guidelines

Introduction: The Borderline Intellectual Functioning (BIF) is conceptualized as the frontier that delimits normal intellectual functioning from intellectual disability (IQ 71-85). In spite of its magnitude, its prevalence cannot be quantified and its diagnosis has not yet been defined. Objectives: To elaborate a conceptual framework and to establish consensus guidelines. Method: A mixed qualitative methodology, including frame analysis and nominal groups techniques, was used. The literature was extensively reviewed in evidence based medical databases, scientific publications, and the grey literature. This information was studied and a framing document was prepared. Results: Scientific publications covering BIF are scarce. The term that yields a bigger number of results is Borderline Intelligence. The Working Group detected a number of areas in which consensus was needed and wrote a consensus document covering the conclusions of the experts and the framing document. Conclusions: It is a priority to reach an international consensus about the BIF construct and its operative criteria, as well as to develop specific tools for screening and diagnosis. It is also necessary to define criteria that enable its incidence and prevalence. To know what interventions are the most efficient, and what are the needs of this population, is vital to implement an integral model of care centred on the individual. (C) 2011 SEP y SEPB.
