They also aim to find out whether the patients are satisfied with the help provided, whether the latter intend to consult their GP in case of a crisis, what their present psychosocial functioning is and whether there were any recurrences of suicidal behaviour. The psychosocial functioning is measured by means of the following instruments (which have been validated internationally): the General Health Questionnaire (GHQ12), the Beck Hopelessness Scale (BHS), the Positive and Negative Affectivity Scale (PANAS).
Le fonctionnement psychosocial est mesuré à l’aide des instruments suivants (validés internationalement): General Health Questionnaire (GHQ12), l’échelle de Beck, qui évalue l’anxiété et la dépression, Positive and Negative Affectivity Scale (PANAS).

Nevertheless, some studies, including the 2004 Belgian Health Survey discussed above, throw some light on this problem in so far as they focus on measuring notions such as psychological illbeing (Book II of the Health Interview Survey – Belgium 2004, pp 204-209): “The psychological well-being assessed in the 2004 Belgian Health Survey is measured by means of an instrument (GHQ-12, General Health Questionnaire) that uses scores ranging from 0 to 12. A higher score indicates a higher probability/severity of psychological ill-being.
« Le bien-être/mal-être psychologique évalué dans l’enquête de santé en Belgique de 2004 est mesuré grâce à un outil (GHQ-12, General Health Questionnaire) dont l’échelle de mesure va de 0 à 12, où un score plus élevé indique une plus grande probabilité/sévérité du mal-être psychologique.
