Post-traumatic stress disorder (PTSD) is a mental and behavioral disorder that develops from experiencing a traumatic event, such as sexual assault, warfare, traffic collisions, child abuse, domestic violence, or other threats on a person's life or well-being. Symptoms may include disturbing thoughts, feelings, or dreams related to the events, mental or physical distress to trauma-related cues, attempts to avoid trauma-related cues, alterations in the way a person thinks and feels, and an increase in the fight-or-flight response. These symptoms last for more than a month after the event and can include triggers such as misophonia. Young children are less likely to show distress, but instead may express their memories through play. A person with PTSD is at a higher risk of suicide and intentional self-harm.
Psychological trauma is an emotional response caused by severe distressing events that are outside the normal range of human experiences. It must be understood by the affected person as directly threatening the affected person or their loved ones generally with death, severe bodily injury, or sexual violence; indirect exposure, such as from watching television news, may be extremely distressing and can produce an involuntary and possibly overwhelming physiological stress response, but does not produce trauma per se. Examples of distressing events include violence, rape, or a terrorist attack.
Psychological resilience is the ability to cope mentally and emotionally with a crisis, or to return to pre-crisis status quickly.

Childhood trauma is often described as serious adverse childhood experiences (ACEs). Children may go through a range of experiences that classify as psychological trauma; these might include neglect, abandonment, sexual abuse, emotional abuse, and physical abuse. They may also witness abuse of a sibling or parent, or have a mentally ill parent. These events can have profound psychological, physiological, and sociological impacts leading to lasting negative effects on health and well-being. These events may include antisocial behaviors, attention deficit hyperactivity disorder (ADHD), and sleep disturbances. Additionally, children whose mothers have experienced traumatic or stressful events during pregnancy have an increased risk of mental health disorders and other neurodevelopmental disorders.

In psychology, posttraumatic growth (PTG) is positive psychological change experienced as a result of struggling with highly challenging, highly stressful life circumstances. These circumstances represent significant challenges to the adaptive resources of the individual, and pose significant challenges to the individual's way of understanding the world and their place in it. Posttraumatic growth involves "life-changing" psychological shifts in thinking and relating to the world and the self, that contribute to a personal process of change, that is deeply meaningful.

Social ecology studies relationships between people and their environment, often the interdependence of people, collectives and institutions. Evolving out of biological ecology, human ecology, systems theory and ecological psychology, social ecology takes a “broad, interdisciplinary perspective that gives greater attention to the social, psychological, institutional, and cultural contexts of people-environment relations than did earlier versions of human ecology.” The concept has been employed to study a diverse array of social problems and policies within the behavioural and social sciences.

Early childhood trauma refers to various types of adversity and traumatic events experienced during the early years of a person's life. This is deemed the most critical developmental period in human life by psychologists. A critical period refers to a sensitive time during the early years of childhood in which children may be more vulnerable to be affected by environmental stimulation. These traumatic events can include serious illness, natural disasters, family violence, sudden separation from a family member, being the victim of abuse, or suffering the loss of a loved one. Traumatic experiences in early childhood can result in severe consequences throughout adulthood, for instance developing post-traumatic stress disorder, depression, or anxiety. The effects of this trauma can be experienced very differently depending on factors such as how long the trauma was, how severe and even the age of the child when it occurred. Negative childhood experiences can have a tremendous impact on future violence victimization and perpetration, and lifelong health and opportunity. However, not all children who are exposed to negative stimuli in early childhood will be affected severely in later life; some children come out unscathed after being faced with traumatic events, which is known as resilience. Many factors can account for the invulnerability displayed by certain children in response to adverse social conditions: gender, vulnerability, social support systems, and innate character traits. Much of the research in this area has referred to the Adverse Childhood Experiences Study (ACE) study. The ACE study found several protective factors against developing mental health disorders, including mother-child relations, parental health, and community support. However, having adverse childhood experiences creates long-lasting impacts on psychosocial functioning, such as a heightened awareness of environmental threats, feelings of loneliness, and cognitive deficits. Individuals with ACEs are more prone to developing severe symptoms than individuals in the same diagnostic category.
