In addition to a general depressive symptom factor, a complete picture must include factors reflecting typical\/atypical vegetative symptoms, cognitive symptoms (hopelessness\/suicidal ideation), and an agitated symptom factor characterized by anxiety, guilt, helplessness and irritability. Prior cross-cultural studies, factor analyses of MD in Western populations and empirical findings in this sample showing risk factor profiles similar to those seen in Western populations suggest that our results are likely to be broadly representative of the human depressive syndrome.<\/jats:p><\/jats:sec>","DOI":"10.1017\/s003329171300192x","type":"journal-article","created":{"date-parts":[[2013,8,7]],"date-time":"2013-08-07T09:11:08Z","timestamp":1375866668000},"page":"1391-1401","source":"Crossref","is-referenced-by-count":42,"title":["The
