According to the positive psychology background, the focus on constructive dimensions of individual functioning implies a critical change on the paradigm from the merely analysis focused on individual pathology (and on the need to repair the damage) to an approach focused on self-actualization and well-being (Seligman & Csikszentmihalyi, 2000). Despite the progressive investment in this area, the study of distress and disorders has been greater than in the positive individual functioning. As such, in order to address the limitations of traditional models of mental health, a range of theoretical models, with different labels but focused on the same conceptual meanings, has emerged from the positive psychology framework. For instance, there are authors proposing a Dual-factor system of mental health (Greenspoon & Saklofske, 2001), others the The two continua model of mental illness and health (Westerhof & Keyes, 2010) and others the Dual-factor model of mental health (Wang, Zhang & Wang, 2011). All these models suggest that mental health must be viewed as a complete state, reflecting the integration of a positive (well-being) and a negative (psychopathology) dimension of adjustment, in two continuums but related factors (Wang et al., 2011; Westerhof et al., 2010). This conceptualization of mental health has been empirically tested and results supported the model with two separate dimensions (Keyes, 2005; Wilkinson & Walford, 1998). This evidence of a dual-factor model of mental health allows the classification of
