This paper describes the constructs of pathological self-deception (the inability to detect the negative effect of one’s own behaviour) and mystification (an extreme form of self-deception which affects daily life) by way of a brief historical review of the instruments used to evaluate self-deception and desirability. The Self-Deception and Mystification Inventory (IAM-40) is presented for the first time; it is made up of forty items and five factors (insincerity, manipulation, denial mechanisms, an interested perception of reality and mystification).
The general objective of this investigation is to validate the Inventory of Self-Deception, including both its general scale and the factors and constructs of self-deception and mystification, in a study of 159 addict patients (clinical population sample) and 124 general population participants. Significant differences are found, as predicted, between both subpopulations, with a greater level of pathology of all studied indicators in the clinical sample. The clinical existence of self-deception and mystification is concluded. The IAM-40 is also proven to be an adequate and useful instrument for diagnostic purposes and for day-to-day clinical management. The critical discussion is based on a proposal for psychotherapeutic and sociotherapeutic ad hoc treatment.
