Developmental psychology
Attachment theory, originally developed by John Bowlby, focuses on the importance of open, intimate, emotionally meaningful relationships. Attachment is described as a biological system or powerful survival impulse that evolved to ensure the survival of the infant. A child who is threatened or stressed will move toward caregivers who create a sense of physical, emotional and psychological safety for the individual. Attachment feeds on body contact and familiarity. Later Mary Ainsworth developed the Strange Situation protocol and the concept of the secure base.
Ilan Meyer
Meyer developed a model of that describes the relationship of social stressors and mental disorders and helps to explain LGBT health disparities. The model has guided his and other investigators’ population research on LGBT health disparities by identifying the mechanisms by which social stressors impact health and describing the harm to LGBT people from prejudice and stigma. The Institute of Medicine (IOM) cited the model as one of four cross-cutting perspectives (the only one stemming from LGBT scholarship) recommended for the study of LGBT health.
