Material and Methods: 50 cases diagnosed with Bipolar Disorder, depressive episode (BD) and 50 cases diagnosed with Major Depressive Disorder (MDD) according to DSM-IV, are recruited into this study. Healthy individuals from our hospital staff are taken into this study. These healthy individuals do not have any psychiatric sympthoms and psychiatric treatment according to SCID-NP. Scale validity, internal consistency and reliability are stated by factor analysis and another test correlations. Sensitivity, specificity, prevalence and cut off point are determined by ROC curve. Results: The average point of SHPS in cases diagnosed with BD and MDD are higher than healthy individuals (p= 0.01 ve p< 0.001). Internal consistency of the scale is calculated as 0.92. In factor analysis, physical pleasure correspondes 48 % of the variance, social pleasure correspondes 22 % of the variance. There found a moderate correlation between SHPS and Hamilton Depression Rating Scale (HDRS). Sensitivity is determined as 0.935 and specificity is determined as 0.820 in ROC curve. According to this prevelance is determined as 10.9 % and cut off point is calculated as 28 and more in 95 % confidence interval. Conclusion: It is stated that SHPS distinguishes the cases diagnosed with BD and MDD from healthy individuals. Turkish forms of SHPS is valid and reliable instrument, also short, simple, based on self report and easy to apply. [Cukurova Med J 2015; 40(2.000): 252-257]
