Asking "What's wrong in you life?" → Person sees more problems I think if you ask a person &quot;What's wrong in your life?&quot; several times (for example monthly) the person starts to focus on negative things.
Maybe questions like this can have a negative outcome. The person will focus on (maybe even search) things which are negative. These questions might influence his attention. And finally the person might get depressed or the relationship gets worse.
I am new to psychology. Is there a term for this? Or are there researches on this topic?

This is priming effect. There are some experiments closely related to your observation:

In this paper, the significant change in correlation between happiness and subject of previously asked question was observed, as against to the same question asked after the question about happiness.
Also framing effect can be related to your question: the way which question about person's life is asked can change the expected answer to the question (along with temporal opinion about given subject). When the process is repetitive, it can factor into more permanent change.

Related to this is also confrmation bias - in case of a question about some negative aspects of some subject (in this case life), more negative memories about it is primed, what substancially changes the way we process the subject
