ABSTRACT

Background: Anhedonia is one of the negative symptoms of schizophrenia. For better understanding and creating a good strategy for patient’s treatment sometimes we need to know the level of anhedonia. We conducted the study of adaptation and validation the Snaith-Hamilton pleasure scale for Ukrainian speaking persons. Material and methods: Totally 328 persons were randomized on schizophrenia spectrum and healthy controls groups: 205 Ukrainian-speaking inpatients with schizophrenia spectrum disorders and 123 healthy volunteers people. These groups were similar with respect to race (white Caucasian), gender, age, socioeconomic status. For assessment we used Ukrainian adaptation of the Snaith-Hamilton pleasure scale, Positive and Negative Syndrome Scale, Montgomery-Asberg depression rating scale. For calculating was used SPSS 20 for Windows. Results: In observed groups we found significant difference in age (p<0,05), marital (p<0,01) and occupational (p<0,01) statuses, and in anhedonia level (p<0,05). Among patients anhedonia had observed in 52,2% cases with a common average score on SHPS of 36,4±13,95 points (normal ≥ 40 points). They had so called “Social” anhedonia. Patients were very anhedonic in interests and social interactions. Healthy controls in general were non-anhedonic. They had anhedonia in 21,1% cases. The common score on SHPS was 45,07±7,39 points. The sensitivity of the scale is 58%, specificity 78%, PPV is 82%. Accuracy of the scale is 0,66. Conclusions: The Snaith-Hamilton Pleasure Scale Ukrainian language version had shown moderate sensitivity but good specificity. The scale has excellent reliability, good current validity, and good positive predictive value; its use may facilitate negative assessment in patients with schizophrenia spectrum disorders in daily psychiatry clinical practice and in research studies.
