Research discovered that people with depression and anxiety who had a traumatic childhood often grew up to be angry adults, and that the more severe the trauma, the more enraged the adult. This complicates the treatment of depression and anxiety, in addition to affecting social interactions and mental health.
The study was presented at the European Congress of Psychiatry in Paris.
More than 40% of patients with both anxiety and depression were shown to be prone to anger, according to earlier research. Comparatively, just 5 per cent of healthy controls have this problem. The ongoing Netherlands Study of Depression and Anxiety, which was created to look at the progression of depression and anxiety disorders over many years, provided the data for the current study.
Beginning in 2004, the study took participants between the ages of 18 and 65 and began to question them about their childhood; by the end of the study, 2276 people had taken part. Working over years they were able to discover if there had been any history of childhood trauma, such as parental loss, parental divorce, or being placed in care. They also asked participants about neglect, and emotional, physical and sexual abuse. The participants were also later checked for a variety of psychiatric symptoms related to depression and anxiety, including their tendency to anger and how this manifested itself.
Lead researcher Nienke De Bles (Leiden University, the Netherlands) said: "There is surprisingly little research on anger in general. The Netherlands Study of Depression and Anxiety is a well-established study which has produced a lot of good scientific data, but there has not been any significant work looking at the data on childhood trauma and seeing if this is linked to increased levels of anger. We have now found that there is a link".
We found that anxious or depressed people with a history of emotional neglect, physical or psychological abuse, were between 1.3 and 2 times more likely to have anger problems. We also found that the more traumatic the childhood experience, the greater the tendency towards adult anger. We can't definitively say that the trauma causes the anger, but the link is clear.
We found that children who suffered emotional neglect had an increased tendency to grow into adults who were irritable or easily angered, whereas those who had been physically abused had a greater tendency towards anger attacks or antisocial personality traits. Sexual abuse tended to result in a suppression of anger, possibly because of a greater sensitivity to rejection - but this needs to be confirmed".
She continued: "Being easily angered can have several consequences. It can make personal interactions more difficult, and it can have consequences for your mental health and well-being. But people who get angry easily also have a greater tendency to discontinue psychiatric treatment, so this anger may mean that it reduces their chances of a better life".
If the person but bottles the anger up, the therapist may not see it. We believe that it should be standard practice to ask depression and anxiety sufferers about anger and past trauma, even if the patient is not exhibiting current anger. Psychiatric treatments for past trauma may differ to treatment for current depression, so the psychiatrist need to try to understand the cause so that they can offer the correct treatment to each patient".
