Overview

As an emotion is accompanied by various physiological responses, body language, goal directed behaviour, appraisal etc. Caliberation of anhedonia can be done by various ways, e.g. behavioral , electrophysiological, hemodynamic, interview-based measures, and self-reports.

Diagnostic Criteria

Assessing rather than diagnosis is made for anhedonia as it is not a psychiatric disorder in itself. Self-questionnaires have been more frequently such as,

  • Chapman Physical Anhedonia Scale the (PAS) and its revised forms, it is a 61 item instrument
  • Revised Physical Anhedonia Scale (R-PAS)
  • Fawcett-Clark Pleasure Scale (FCPS)
  • Snaith-Hamilton Pleasure Scale (SHPS or SH APS)

Above instruments caliberate hedonic capacity. However the psychometric properties are different. Patients with higher scores on self-report measures of anhedonia tends to have lower hedonic responses to,

  • Emotive pictures
  • Positive emotional scripts, and sucrose solution
  • Emotion-eliciting slides w.r.t. facial expression and heart rate.[1][2][3]

Social Anhedonia

There are several self-report psychometric measures of schizotypy which each contain subscales related to social anhedonia:

  • Revised Social Anhedonia Scale—Chapman Psychosis Proneness Scales [4][5]
  • No Close Friends Subscale—Schizotypyal Personality Questionnaire [6]
  • Introverted Anhedonia Subscale—Oxford Liverpool Inventory of Feelings & Experiences [7]
