ObjectivesTo compare self-reports of five basic emotions across four samples: healthy, chronic pain, depressed and PTSD, and to investigate the extent to which basic emotion reports discriminate between individuals in healthy or clinical groups.
MethodsIn total, 439 participants took part in this study: healthy (N = 131), chronic pain (N = 220), depressed (N = 24) and PTSD (N = 64). Participants completed the trait version of the Basic Emotion Scale (Dalgleish & Power, 2004). Basic emotion profiles were compared both within each group and between the healthy group and each of the three other groups. Discriminant analysis was used to assess the extent to which basic emotions can be used to classify participants as belonging to the healthy group or one of the clinical groups.2
ResultsIn the healthy group, happiness was experienced more than any other basic emotion.This was not found in the clinical groups. In comparison to healthy participants, the chronic pain group experienced more fear, anger and sadness; the depressed group reported more sadness; and the PTSD group experienced all of the negative emotions more frequently. Discriminant analysis revealed that happiness was the most important variable in determining whether an individual belonged to the healthy group or one of the clinical groups. Anger was found to further discriminate between depressed and chronic pain individuals.
ConclusionThe findings demonstrate that basic emotion profile analysis can provide a useful foundation for the exploration of emotional experience both within and between healthy and clinical groups.
Key Practitioner Message• More frequent experiences of happiness relative to discrete negative emotions most clearly discriminate between individuals in healthy and clinical groups.More frequent anger experiences further discriminate between individuals with chronic pain and those with depression while disgust levels help discriminate between those with PTSD and depression.• More frequent experiences of high arousal negative emotions -fear, anger and disgust are characteristic of individuals with PTSD.• Fear is the most frequently experienced negative emotion in both healthy and clinical groups. Higher levels of fear compared to other discrete negative emotions are not necessarily an indicator of psychopathology. Consideration of emotional profiles more generally and the relative frequency with which happiness is experienced relative to negative emotions may be more useful in delineating between healthy individuals and those with chronic pain, depression or PTSD.
3Although emotions play an important role in psychopathology, few studies have applied models of everyday emotions to research in psychopathology. Nonetheless,
