[Changes of coefficients of sleep onset, sleep maintenance and awakenings in most common psychiatric disorders in inpatients].
BACKGROUND
The study's purpose was to find differences of selected psychopathological syndromes according to characteristic disturbances of sleep which are present in them.


METHODS
Among 194 patients (mean age: 42.27 +/- 14.15) 108 were women (mean age: 42.97 +/- 14.13) and 86 were men (mean age: 41.38 +/- 14.22). Psychiatric examination and sleep disturbance evaluation was done with the use of our own questionnaire: Multidimensional System for Evaluation of Sleep Disorders (MSESD) were performed the third day after admission to a psychiatric ward. Sleep was analysed according to coefficients which described falling asleep, sleep maintenance and awakenings. These coefficients were created according to parameters obtained from MSESD.


RESULTS
Coefficients obtained from the "schizophrenic disorders" and "personality disorders" groups did not differ significantly from the average coefficients for all the patients. The common feature among other groups of patients was the elevation of the coefficient of falling asleep especially for the "organic" and "depressive" disorders groups. The most pronounced elevation of the falling asleep coefficient was detected in the "depression without somatic features" group, however this elevation was also clearly seen in the "reactive disorders" group. In the latter group all other coefficients were also significantly elevated.


CONCLUSIONS
Constructed coefficients of sleep disturbances may be useful for diagnosing and differentiating the most often psychiatric disorders in inpatients.
