Biomedical and psychosocial risk factors include a family history of depression, parental conflict, female sex, poor peer relationships, childhood abuse or neglect, stressful life events, negative thinking, and chronic illness.
One negative change is the dramatic increase in the probability of developing clinical depression, a psychological disorder characterised by low mood accompanied by a variable set of other symptoms such as change in appetite, and sleep, loss of concentration, guilt and suicidality that persist for at least 2 weeks and impairs function.
