This script implements Millisecond's computerized version of the THE SELF-ASSESSMENT ANHEDONIA SCALE (SAAS) by Olivares et al (2005). Anhedonia is the reduced ability to experience pleasure.
Olivares,JM, Berrios, GE, & Bousoño, M. (2005). The self-assessment anhedonia scale (SAAS). Neurology Psychiatry and Brain Research 12(3):121-133. DOI:10.1037/t00443-000
6 minute
self-report measure consisting of 27 questions, each with 3-point Likert Scales
(intensity, frequency, and change scales)
intensity: slider scale with anchors "A LOT" (0) - "NOT AT ALL" (10) in this script, the anchor "NOT AT ALL" is used instead of 'NOTHING'
frequency: slider scale with anchors "NEVER" (10) - "ALWAYS" (0)
change: slider scale with anchors "SAME AS BEFORE" (0) - "LESS THAN BEFORE" (10)

Summary Variables |
|
| saasTotalAnhedoniaScore | Sum of all scores (3*27), Range 0-810 |
| saasPhysicalAnhedoniaScore | Sum of items 1, 2, 4, 7, 9, 10, 13, 14, 15, 23, 24, 26; Range: 0-360 |
| saasIntellectualAnhedoniaScore | Sum of items 3, 5, 11, 12, 19, 20, 21, 25, 27; Range: 0-270 Note (KB): q27 seems similar to q14 but was included into this subscale by Olivares et al (2005) |
| saasSocialAnhedoniaScore | Sum of items 6, 8, 16, 17, 18, 22; Range: 0-180 |
| saasTIS | Sum of all 27 intensity responses ('a'), Range: 0-270 |
| saasTFS | Sum of all 27 frequency responses ('b'), Range: 0-270 the responses were reversed scored before they were added up |
| saasTCS | Sum of all 27 change responses ('c'), Range: 0-270 |
Individual Responses (A = Intensity; B = Frequency (Reversed Scored); C = Change) |
|
| q1a | The intensity response to q1 on a scale from 0-10 Example: if RAW response was 84 (out of 100), the score would be 8.4 |
| q1b | The intensity response to q1 on a scale from 0-10 reversed scored. Example: if RAW response was 84 (out of 100), the reversed score would be 1.6 |
| q1c | The change response to q1 on a scale from 0-10 Example: if RAW response was 84 (out of 100), the score would be 8.4 (same for q2-q27) |
