Despite the rapid evolution of measurement technologies in biomedicine and genetics, most of the recent studies aiming to explore the genetic background of multifactorial diseases were only moderately successful. One of the causes of this phenomenon is that the bottleneck of genetic research is no longer the measurement process related to various laboratory technologies, but rather the analysis and interpretation of results. The commonly applied univariate methods are inadequate for exploring complex dependency patterns of multifactorial diseases which includes nearly all common diseases, such as depression, hypertension, and asthma. A comprehensive investigation requires multivariate modeling methods that enable the analysis of interactions between factors, and allow a more detailed interpretation of studies measuring complex phenotype descriptors. In this paper we discuss various aspects of multivariate modeling through a case study analyzing the effect of the single nucleotide polymorphism rs6295 in the HTR1A gene on depression and impulsivity. We overview basic concepts related to multivariate modeling and compare the properties of two investigated modeling techniques: Structural Equation Modeling and Bayesian network based learning algorithms. The resulting models demonstrate the advantages of the Bayesian approach in terms of model properties and effect size as it allows coherent handling of the weakly significant effect of rs6295. Results also confirm the mediating role of impulsivity between the SNP rs6295 of HTR1A and depression.

According to modern psychological theories the human life implies continuous development, the efficient solution of age-specific problems is necessary to the successful transition of age-periods. The phases of transition are very vulnerable against the accidental stressors and negative life-events. Thus the problem-solving capacity may run out, which impairs chance of the successful coping with stressful events. It may result in some negative consequences, such as different psychopathological symptoms (depression, anxiety, psychosis) or even suicidal behaviour. For that reason we have to pay special attention to the symptoms of psychological crisis and the presuicidal syndrome. In certain life-cycle transitions (such as adolescent, middle or elderly age) the personality has special vulnerability to the development of psychological and psychopathological problems. In this article the most important features of life-cycles and psychopathological symptoms are reviewed. The developmental and age-specific characteristics have special importance in understanding the background of the actual psychological crisis and improving the efficacy of the treatment. Using the complex bio-psycho-socio-spiritual approach not only the actual psychopatological problems, but the individual psychological features can be recognised. Thus the effective treatment relieves not only the actual symptoms, but will increase the chance for solving further crises.

Depression is a highly prevalent mental illness with increasing burden for the patients, their families and society as well. In spite of its increasing importance, we still do not have complete understanding either of the phenomenology or the etiopathological background of depression, and cross-country, cross-ethnic and cross-cultural differences in the prevalence and symptomatic manifestation of depression further obscure this picture. Culturally-related features of depressive illness are gaining more importance in clinical practice with the increasing migration trends worldwide. In spite of the differences replicated in multiple studies, no exhaustive explanations are offered so far. In the present paper we describe the most consistently replicated findings concerning the most important cross-national differences in the rates and characteristics of depression with a short comment on possible background factors.
