The evaluation of transdiagnostic model based on Lynch’s theory with regard to depression in nonclinical population

The objective of this study were to investigate Lynch’s theory of psychopathology with regard to depression. students from three universities in Tehran (n= ۵۲۱) was selected by convenience sampling method. The measures used in this study were negative temperament scale of Schedule of Non-adaptive and Adaptive Personality, Temporal Experience of Pleasure Scale, maladaptive perfectionism subscales of Frost Multidimensional Perfectionism Scale, Ambivalence over Emotional Expressiveness Questionnaire, Personal Need for Structure Scale, Inventory of Interpersonal Problems, Social Safeness and Pleasure Scale and Beck Depression Inventory. The results showed that the model has good fit with data. Bootstrap analysis also confirmed the mediating role of over-controlling and social disconnectedness. Accordingly, the interaction of sensitivity to threats, sensitivity to rewards and parental perfectionism leads to development of an over-controlling coping style; this coping style leads to disturbance in social connectedness and subsequently to depression. Therefore, the results of this study support the Lynch’s model of psychopathology for depression.
