Need to Evaluate: NES (Jarvis and Petty 1996)

The scale of Need to Evaluate: NES were developed by Jarvis and Petty (1996) which is unidimensional measure using a 5-point Likert scale items where 1 = extremely uncharacteristic, 2 = somewhat characteristic, 3 = uncertain, 4 = somewhat characteristic, and 5 = extremely characteristic. The scale range from 16 to 80 items. This scale has five constructs are;

  • NES
  • Relation of the NES to Other Scales
  • Attitudes Toward Social and Political Issues
  • Spontaneous Evaluative Thought
  • Autobiographical Narratives

All five constructs components contain items specific to assessment of the positive and/or negative qualities of an object.

The authors state:

" Need to evaluate is believed to be an individual difference variable that affects, and is affected by, numerous socially based attitudes. Thus, the Need to Evaluate Scale (NES) assesses individual differences in the propensity to engage in evaluation."
