Objective: Anhedonia, which is defined as diminished capacity of
having pleasure, is a common symptom in many mental disorders. It has
been aimed in this study to adapt to the Turkish language the Snaith-
Hamilton Pleasure Scale Clinician Administered Form (SHAPS-C) and
examining reliability and validity of Snaith-Hamilton Pleasure Scale
Clinician Administered Turkish Form (SHAPS-C-TR) which measures
anhedonia in clinical and healthy samples.
Method: Two groups consisting of 63 participants consulting the
psychiatry clinic and 67 non-clinical participants were included in the
study. Data were collected with the Turkish version of the SHAPS-C
(the SHAPS-C-TR), the Beck Depression Inventory (BDI), the
Montgomery-Asberg Depression Rating Scale (MADRS) and the
Positive Negative Affect Scale (PANAS).
Results: The Kuder-Richardson internal consistency coefficient for
the entire participants, the clinical and the non-clinical group were,
0.765, 0.813 and 0.657 respectively. The intra-class coefficient for
test-retest reliability was 0.732. The total score on the SHAPS-C-TR
significantly correlated with the scores on the anhedonia items of the
BDI and the MADRS but not the scores on anxiety items. The PANAS
positive symptoms scores were negatively correlated with the SHAPSC-
TR total score. In the clinical group, the participants followed up
with depression had significantly higher SHAPS-C-TR score than the
rest of the participants. A similar difference was not demonstrated by
the scores of the clinical group participants followed up with anxiety
disorder. Scores on the SHAPS-C-TR did not vary with respect to the
demographic characteristics of the participants.
Conclusion: The SHAPS-C-TR is a valid and reliable measurement
tool to assess anhedonia in both clinical and non-clinical individuals
irrespective of differences in demographic features.
