Alfred Adler in the context of "Psychoanalytic"

Lifestyle is the interests, opinions, behaviours, and behavioural orientations of an individual, group, or culture. The term "style of life" (German: Lebensstil) was introduced by Austrian psychologist Alfred Adler in his 1929 book, The Case of Miss R., with the meaning of "a person's basic character as established early in childhood". The broader sense of lifestyle as a "way or style of living" has been documented since 1961. Lifestyle is a combination of determining intangible or tangible factors. Tangible factors relate specifically to demographic variables, i.e. an individual's demographic profile, whereas intangible factors concern the psychological aspects of an individual such as personal values, preferences, and outlooks.

A rural environment has different lifestyles compared to an urban metropolis. Location is important even within an urban scope. The nature of the neighborhood in which a person resides affects the set of lifestyles available to that person due to differences between various neighborhoods' degrees of affluence and proximity to natural and cultural environments. For example, in areas near the sea, a surf culture or lifestyle can often be present.

Psychoanalysis is a set of theories and techniques of research to discover unconscious processes and their influence on conscious thought, emotion and behavior. Based on dream interpretation, psychoanalysis is also a talk therapy method for treating mental disorders. Established in the early 1890s by Sigmund Freud, it takes into account Darwin's theory of evolution, neurology findings, ethnology reports, and, in some respects, the clinical research of his mentor Josef Breuer. Freud developed and refined the theory and practice of psychoanalysis until his death in 1939. In an encyclopedic article, he identified its four cornerstones: "the assumption that there are unconscious mental processes, the recognition of the theory of repression and resistance, the appreciation of the importance of sexuality and of the Oedipus complex."

Freud's earlier colleagues Alfred Adler and Carl Jung soon developed their own methods (individual and analytical psychology); he criticized these concepts, stating that they were not forms of psychoanalysis. After the author's death, neo-Freudian thinkers like Erich Fromm, Karen Horney and Harry Stack Sullivan created some subfields. Jacques Lacan, whose work is often referred to as Return to Freud, described his metapsychology as a technical elaboration of the three-instance model of the psyche and examined the language-like structure of the unconscious.

Personality describes the behavioral, cognitive, and emotional patterns that make up a person’s unique adjustment to life. Personality is relatively stable, but can change over time due to experiences and developmental processes. Although there is no consensus definition of personality, most theories in personality focus on traits, motivation, skills, and identity.

Research in personality psychology generally attempts to explain the characteristics of a person that underlie differences in behavior. Personality characteristics are related to many life outcomes, such as work and relationship success, to mental health, well-being and longevity. Over time, psychologists have taken many different approaches to study personality, which can be organized across dispositional, biological, intrapsychic (psychodynamic), cognitive-experiential, social and cultural, and adjustment domains. The various approaches used to study personality today reflect the influence of the first theorists in the field, a group that includes Sigmund Freud, Alfred Adler, Gordon Allport, Hans Eysenck, Abraham Maslow, and Carl Rogers.

Depth psychology (from the German term Tiefenpsychologie) refers to the practice and research of the science of the unconscious, covering both psychoanalysis and psychology. It is also defined as the psychological theory that explores the relationship between the conscious and the unconscious, as well as the patterns and dynamics of motivation and the mind. The theories of Sigmund Freud, Carl Gustav Jung, and Alfred Adler are all considered its foundations.

The term style of life (German: Lebensstil) was used by psychiatrist Alfred Adler as one of several constructs describing the dynamics of the personality.
