RESUMO
OBJECTIVE: Describe the frequency and characteristics of Mexican Social Security workers with malingering disorder that request disability pension. MATERIAL AND METHODS: Comparative survey made among 136 workers seen during 2001, which were divided into three groups: malingering workers (MW), workers without disability (WOD), and workers with disability (WWD). We administered the Z Test for scaled variables and Z2 Test for nominal variables to identify group differences RESULTS: The incidence ofmalingering was of 2.2/100,000 workers. Mean age was 41.9 +/- 10.1 years, 440 was the average number of days of labor disability; 51 (37%) workers were malingerers. 35 (26%) workers were work disabled and 50 (37%) without disability. Malingerers had higher level of schooling compared with WOD and WWD (p < 0.02); most worked at the Social Security (p < 0.05), with lower number of previous jobs (p < 0.05), presented longer work disability (p < 0.05). Depressive symptoms were not frequently noted (p < 0.025) and all had normal electroencephalogram and brain computed tomography studies. CONCLUSIONS: Malingering workers who request work disability pensions follow a particular pattern that differs from other workers that request disability assessment at the Social Security Institute of Mexico.

Objetivo: Describir la frecuencia y características de los trabajadores afiliados a la Seguridad Social con trastornos de simulación que solicitan pensión por invalidez. Material y métodos: Encuesta comparativa realizada en 136 trabajadores atendidos durante 2001, en quienes se identificaron tres grupos: trabajadores simuladores (TS), trabajadores sin invalidez (TSI), y trabajadores con invalidez (TCI). Para identificar las diferencias entre grupos, se aplicó la prueba z para variables escalares, y prueba de χ2 para variables nominales. Resultados: La incidencia de simuladores fue de 2.2/100,000 trabajadores. La edad media de los trabajadores fue: 41.9 ± 10.1 años, 440 fue el promedio de días de incapacidad laboral; 51(37%) trabajadores presentaron simulación. 35(26%) trabajadores fueron invalidados para el trabajo y 50(37%) sin invalidez. Los trabajadores simuladores tienen mayor nivel de escolaridad que TSI y TCI (p < 0.02); laboran mayoritariamente en la seguridad social (p < 0.05), con menor número de empleos previos (p < 0.05), presentan incapacidad laboral de mayor duración, (p<0.05), los síntomas depresivos son infrecuentes (p < 0.025) con electroencefalograma y tomografía normales. Conclusiones: Los trabajadores simuladores que demandan pensión por invalidez para el trabajo presentan características particulares diferentes a otros trabajadores que solicitan un estado de invalidez.
