There has long been interest in describing emotional experience in terms of underlying dimensions, but traditionally only two dimensions, pleasantness and arousal, have been reliably found. The reasons for these findings are reviewed, and integrating this review with two recent theories of emotions (Roseman, 1984;Scherer, 1982), we propose eight cognitive appraisal dimensions to differentiate emotional experience. In an investigation of this model, subjects recalled past experiences associated with each of 15 emotions, and rated them along the proposed dimensions. Six orthogonal dimensions, pleasantness, anticipated effort, certainty, attentional activity, self-other responsibility/control, and situational control, were recovered, and the emotions varied systematically along each of these dimensions, indicating a strong relation between the appraisal of one's circumstances and one's emotional state. The patterns of appraisal for the different emotions, and the role of each of the dimensions in differentiating emotional experience are discussed.

Form C of the Multidimensional Health Locus of Control (MHLC) scales is an 18 item, general purpose, condition-specific locus of control scale that could easily be adapted for use with any medical or health-related condition. Data from 588 patients with one of four conditions--rheumatoid arthritis, chronic pain, diabetes, or cancer--were utilized to establish the factor structure of Form C and to establish the reliability and validity of the resultant four subscales: Internality; Chance; Doctors; and Other (powerful) People. The alpha reliabilities of the subscales are adequate for research purposes. Data from the arthritis and chronic pain subjects established that the Form C subscales were moderately stable over time and possessed considerable concurrent and construct validity. Some discriminant validity of Form C with Form B of the MHLC was also demonstrated.

Recent research has indicated strong relations between people's appraisals (Smith & Etlsworth, 1985
