Although it has been stated that the majority of suicidal people give definite warnings of their suicidal intention, a percentage of suicidal people may dissemble (or mask), possibly 20%. The aim of this psychological autopsy (PA) study was to explore the mask of suicide, examining age and sex of the decedent, and survivors’ relationship to the deceased. A PA study in Norway, with 120 survivors/informants, was undertaken. Overall, 80% of informants reported manifest and/or latent content of deception (dissembling); well above the 20% suggested. Three main themes emerged from the interviews of the 95 survivors that were related to the mask. In the opinion of the bereaved, reasons for the mask were due to: 1) Inability to adjust/impairment; 2) Relational problems; and 3) Weakened resilience. Differences in masking or (self) deception were found in the age of the decedent, but not in sex, nor in the survivors’ closeness of the relationship. Older deceased people were perceived to exhibit more dissembling, associated to the suicide. Limitations are noted in this beginning study into the mask of suicide, and it is concluded that much greater research is needed to unmask the dangerous dissembling, maybe in some, self-deception.
