First, one needs to differentiate between suicides that attempts that unintentionally resulte in death and intended deaths. The reverse are intended suicides that failed and are registered as attempts. Second, is the factor age. One needs sufficient fysical skills (development to commit suicide. Also, below the age childrensee death as reversal. Hence, most 'suicides' before that age  aren't real suicides. They may be attempts to visit a deceased beloved person. Third. (pre-)adolescents and adults can plan their death. Some do this for quite some time. It only needs a trigger to committing the suicide. Fourth, quite a few suicides weren't intended to die, they were attempts to stop inbarable pain, thoughts or hallucinations. Last but not least, there is the problem of definitions.

In my view, l think if children have an underlying predisposition such depression, any masked form of abnormal personalities associated with psychosis may plan and execute their suicidal idealizations. Furthermore, their psychological enigma coupled with delusions of paranoia, hallucinations etc that cant be experienced properly to them; may help in the elucidation of this phenomena from the mental health point of view. Hope that helps Doctor

As a therapist for 24 years, I have personally talked with children who truly wanted to die.  Some of these (the youngest was 5 years old, others 7 areas old and up) had heard about different methods of suicide and were considering the methods available to them.  Some had attempted to kill themselves (hanging, pills, running in front of oncoming vehicles, shooting themselves, walking into a dangerous river, etc.) and were interrupted (hanging cord broke, cut down by someone, someone came along, told a trusted adult hours before, etc., etc.    It all had to do with the very intense level of emotional pain they were feeling at the time.    Note:  I am speaking of experience in the United States.

Problematic remains the question of whether children younger than 9 y.o.a. can sufficiently Judge the essence of death. At least most of them cannot. I agree that pain, emotional or physical, plays an essential role in committing suicide.

In almost all episodes of suicides children only imitated the act of suicide they  had watched in films or TV serials..

and causes of most attempts ....were conflicts in the family front...with parents..

Children blindly imitate the way of responding to emotional trauma...

they will never plan or attempt or execute the act if they are ignorant about the definition or meaning of suicide...

they will never plan or commit ... even if they know what is "suicide"..

they will only imitate ....if they know what  "suicide"  is...and how it is being done...

Dear Jeny,

Is this your opinion, your personal practice opinion or is this a result of a study. In latter case I would very much appreciate this respective paper(s).

I would summarise all that has been said with the idea that this is too general a belief, and most likely we will be able to find children (and adults!) who can and who cannot plan or succeed in committing suicide. I would like, however, to ask the reason for this question. Is it theoretical or clinical? I assume that as a clinician, I would not rely on such a view in order not to treat a child with death ideas. 

Refer to the works of professor Béatrice Marianne Ewalds-Kvist  - but to add - planning as executable function is determined by access to resources and intensity of the concern - in terms of stimulus availability and access to it 

Interesting question ... I am trying to study adolescent and youth suicide in the context of my country, and I use roughly age group of 15-25 years old. Somehow some reports of suicides also use this age group. I think the latest government publication here indicated the youngest person who committed suicide (as defined) was something like 14 years old. I am not sure what is the prevalence of completed suicide in your country for those

developmentally a behavior is possible at any age - given the severity of the concern.

You need to unpack two things "belief" and "biological age" more accurately - as sociology provides overview of factors and psychological lens can be used to explore motivations to the behavior - but as commented earlier "children" need to be defined more accurately in terms of biological age - generally within a Criminal Code context - suicide of a child - even if suicide is not recorded as such in Coroner Reports...

Also, the construct of belief needs to be quantified...

And equally - you need to then define what "suicide" means in terms of how does a child perceive this - otherwise you are trying to impose an adult worldview on a child in terms of expectancy of a behavior

Thank you all for the brilliant ideas and responses. They are helpful. 

Any other contribution is welcome.
