Characterizing Transdiagnostic Processes Underlying the Drive to Socially Engage: A Multimeasurement Factor Analytic InvestigationAltered drive to socially engage is a transdiagnostic feature across multiple psychopathologies. Yet, lack of clarity regarding specific processes that constitute social drive, along with insufficient measurement methods, has hindered understanding in this area. This study ascertained the feasibility of approximating difficulties within specific fine-grained social drive processes as proposed by 2 theoretical frameworks: “orienting,” “wanting,” “pursuing,” “liking,” “learning,” and “reticence” within a reward processing framework and “orienting,” “seeking and maintaining,” and “liking” within a social motivation framework.
