The biopsychosocial perspective refers to a coordinated way to deal with psychology that joins three alternate points of view and kinds of examination:biological, psychological, and social-cultural. The biopsychosocial approach is a comprehensive way to deal with understanding a person's conduct that credits it to numerous causes as opposed to only one. This viewpoint takes into consideration the way that the collaborations of our body, mind, and our condition all influence each other in various ways.
A longitudinal study is one that involves repeated observations of the same variables over a period of time (in the example, it was four years). The opposite type of study is a cross-sectional study (one that looks at the variables at a given moment).
