| In research on child psychopathology often two broad domains of psychopathology are recognized. On the one hand the internalizing problems, like anxiety and depression. On the other externalizing problems, like aggression and delinquency. In many children however problems from both domains co-occur. Many questions can be asked regarding such co-occurrence. On the one hand questions on the causal factors that lead to co-occurrence. Do both problems result from a common factor? This could be genetic predisposition or problematic circumstances. Do problems from one domain cause problems from the other? For example delinquency might lead to depressive feelings. Apart from that there are methodological considerations. For example symptoms that are classified under both domains or biases in the way people judge the behavior of children. Many other questions can be asked regarding the consequences of co-occurrence. Do both domains develop independent, or do they influence each other? Will these children get treatment aimed at internalizing or externalizing problems? How do the co-occurring symptoms influence their interpersonal relations? Co-occurrence is an interesting, relevant and much debated topic in current psychopathology research. Although much progress has been made in the past decades, still many questions remain unanswered. The exact plan for my PhD is not yet complete, but my first article will be on consequences of co-occurrence for interpersonal relations and the can of help that is sought for these children. |
