M.S. Ritsner (ed.), Anhedonia: A Comprehensive Handbook Volume II: Neuropsychiatric And Physical Disorders, DOI 10.1007/978-94-017-8610-2_2, © Springer Science+Business Media Dordrecht 2014 Abstract The main objective of this chapter was to carry out a selective review of the main measuring instruments used for the assessment of anhedonia and hedonic capacity. First, we briefl y discuss the historical origins of the concept of anhedonia. Given that one’s conceptualization of a given latent construct guides the development and/or selection of measurement instruments, we consider various conceptualizations and operational defi nitions of anhedonia and hedonic capacity. While doing this, we briefl y discuss the hypothesized special relationship that is thought to exist between anhedonia and schizotypy, the latent construct underlying a diathesis for schizophrenia-spectrum disorders. Following this, we present some clinical interviews and self-report instruments used in the assessment of anhedonia. Some of the instruments are stand-alone measures of anhedonia and/or hedonic capacity (as an indirect measure of anhedonia), while other assays of anhedonia are obtained within the context of a more general assessment of negative symptoms. We have chosen to focus only on those interviews and self-report measures that are either new or of special relevance to research and clinical assessment of schizotypy, schizophrenia, Chapter 2 Measuring Anhedonia in SchizophreniaSpectrum Disorders: A Selective Update

Neuropsychological functioning and social anhedonia: results from a community high-risk study.
Social anhedonia has shown promise as a vulnerability marker for schizophrenia-spectrum pathology. Validity data have come, in part, from findings indicating that cognitive deficits occurring in schizophrenia are also evident in individuals with elevated levels of social anhedonia. However, prior research on this topic has been limited because it has been based almost exclusively on the study o...

Failures to replicate results in psychiatric genetics might be due to our inability to define the heritable phenotype. Instead of relying entirely on classical nosographical approaches, the use of a candidate symptom approach to identify more homogeneous forms of diseases among affected subjects and subclinical traits among first-degree relatives may increase genetic validity. Anhedonia may be ...

College undergraduates (n = 34) identified by deviant scores (at least 1.96 SD above the mean) on the Revised Social Anhedonia (SocAnh) Scale (M. Eckblad, L. J. Chapman, J. P. Chapman, & M. Mishlove, 1982) were compared with control participants (n = 139) at an initial assessment and at a 10-year follow-up evaluation. Twenty-four percent of the SocAnh group were diagnosed with schizophrenia-spe...

Social anhedonia has been employed in psychometric high-risk studies to identify putative schizotypes. To date, this research has focused almost exclusively on college samples. The current study sought to examine the validity of social anhedonia as an indicator of risk for schizophrenia-spectrum disorders within a community sample. Furthermore, we evaluated the role of other individual differen...

Social anhedonia is a promising vulnerability marker for schizophrenia-spectrum pathology. Prior research has demonstrated that individuals with psychometrically-defined social anhedonia show a range of "schizophrenia-like" neurocognitive abnormalities. However, this research is limited in that it is based largely on the study of college students. The present article reports findings from a lon...
