Introduction: To evaluate the perception of lung cancer in the general population to identify obstacles in patient-doctor communications. Methods: A prospective nationwide survey was conducted using a questionnaire and lexical approaches given to 2200 healthy subjects selected within a representative polling database. Results: Of the 1469 subjects eligible for full analysis, most were well informed regarding the epidemiological changes to lung cancer and the main risk factors. The overall survival of patients with lung cancer (32%) was overestimated, and the survival of patients with early stages of lung cancer was underestimated (52%). Lung cancer was identified as a severe disease (82%) with a worse prognosis than other cancers. Most of the population was aware of the main treatments available, except for targeted therapy. Using lexical analyses, we observed that a major proportion considered lung cancer to be a tobacco-induced, life-threatening disease that involved major treatment, and a minor proportion considered it to be an environmentally induced disease. Compared with breast cancer, lung cancer was characterized by a greater feeling of guilt and was more frequently associated with lifestyle. Conclusions: We have identified knowledge gaps in the perception of lung cancer and have highlighted a need for a public information campaign on lung-cancer screening to promote the good survival rate from early-stage disease and the progress achieved with new therapeutic strategies. © 2014 by the International Association for the Study of Lung Cancer.

Self-face recognition has been shown to be impaired in schizophrenia (SZ), according to studies using behavioral tasks implicating cognitive demands. Here, we employed an eye-tracking methodology, which is a relevant tool to understand impairments in self-face recognition deficits in SZ because it provides a natural, continuous and online record of face processing. Moreover, it allows collecting the most relevant and informative features each individual looks at during the self-face recognition. These advantages are especially relevant considering the fundamental role played by the patterns of visual exploration on face processing. Thus, this paper aims to investigate self-face recognition deficits in SZ using eye-tracking methodology. Visual scan paths were monitored in 20 patients with SZ and 20 healthy controls. Self, famous, and unknown faces were morphed in steps of 20%. Location, number, and duration of fixations on relevant areas were recorded with an eye-tracking system. Participants performed a passive exploration task (no specific instruction was provided), followed by an active decision making task (individuals were explicitly requested to recognize the different faces). Results showed that patients with SZ had fewer and longer fixations compared to controls. Nevertheless, both groups focused their attention on relevant facial features in a similar way. No significant difference was found between groups when participants were requested to recognize the faces (active task). In conclusion, using an eye tracking methodology and two tasks with low levels of cognitive demands, our results suggest that patients with SZ are able to: (1) explore faces and focus on relevant features of the face in a similar way as controls; and (2) recognize their own face. © 2016 Bortolon, Capdevielle, Salesse and Raffard.

Background Although some studies reported specifically self-face processing deficits in patients with schizophrenia disorder (SZ), it remains unclear whether these deficits rather reflect a more global face processing deficit. Contradictory results are probably due to the different methodologies employed and the lack of control of other confounding factors. Moreover, no study has so far evaluated possible daily life self-face recognition difficulties in SZ. Therefore, our primary objective was to investigate self-face recognition in patients suffering from SZ compared to healthy controls (HC) using an "objective measure" (reaction time and accuracy) and a "subjective measure" (self-report of daily self-face recognition difficulties). Method Twenty-four patients with SZ and 23 HC performed a self-face recognition task and completed a questionnaire evaluating daily difficulties in self-face recognition. Recognition task material consisted in three different faces (the own, a famous and an unknown) being morphed in steps of 20%. Results Results showed that SZ were overall slower than HC regardless of the face identity, but less accurate only for the faces containing 60%-40% morphing. Moreover, SZ and HC reported a similar amount of daily problems with self/other face recognition. No significant correlations were found between objective and subjective measures (p > 0.05). Limitations The small sample size and relatively mild severity of psychopathology does not allow us to generalize our results. Conclusions These results suggest that: (1) patients with SZ are as capable of recognizing their own face as HC, although they are susceptible to ambiguity; (2) there are far less self recognition deficits in schizophrenia patients than previously postulated. © 2015 Published by Elsevier Ltd.

This study explored the mediation effect of metacognitive beliefs on the relationship between intrusive thoughts and emotional distress in schizophrenia (N=49) and obsessive-compulsive disorder (OCD) (N=35). Intrusive thoughts impact on anxiety and depression through beliefs about uncontrollability and danger of thoughts in schizophrenia. Negative beliefs in general mediated the effect of intrusive thoughts on anxiety in obsessive-compulsive disorder. The results suggest that metacognitive beliefs may be a vulnerability factor for emotional and psychological disorder. © 2014 Elsevier Ireland Ltd. Source

Recent literature has shown the role of social factors, such as childhood negative experiences and attachment styles, in the genesis of psychotic symptoms. So far, despite this association with childhood negative experiences and a wide range of psychiatric disorders, no study has yet attempted to assess early maladaptive schemas (EMSs) in patients with schizophrenia as primary diagnosis. A sample of 48 patients diagnosed with schizophrenia and 44 control participants answered the schema questionnaire short form's French validation, and were assessed with the positive and negative syndrome scale as well as a scale of depression symptomatology. Results showed that, after controlling for depression, patients with schizophrenia achieved higher scores than control subjects on six EMSs. The EMSs were associated with positive, but not negative, symptomatology. After controlling for depression, only the Mistrust/Abuse schema was a significant predictor of positive symptoms accounting for a small portion (12.4%) of the variance. The results highlight the importance of focusing not only on the schizophrenic symptoms but also on the person and his or her subjective development of self. Therefore, these results suggest that Young's schema theory may be applied to schizophrenic patients. © 2013 Elsevier Ireland Ltd. Source
