Individual differences in emotional complexity: their psychological implications.

Two studies explored the nature and psychological implications of individual differences in emotional complexity, defined as having emotional experiences that are broad in range and well differentiated. Emotional complexity was predicted to be associated with private self-consciousness, openness to experience, empathic tendencies, cognitive complexity, ability to differentiate among named emotions, range of emotions experienced daily, and interpersonal adaptability. The Range and Differentiation of Emotional Experience Scale (RDEES) was developed to test these hypotheses. In Study 1 (N=1,129) students completed questionnaire packets containing the RDEES and various outcome measures. Study 2 (N=95) included the RDEES and non-self-report measures such as peer reports, complexity of representations of the emotion domain, and level of ego development measured by a sentence completion test. Results supported all of the hypotheses, providing extensive evidence for the RDEES's construct validity. Findings were discussed in terms of the role of emotional complexity in ego maturity and interpersonal adaptability.

Culture-specific patterns in the prediction of life satisfaction: roles of emotion, relationship quality, and self-esteem.

This study was conducted to explore the culture-specific roles of emotion, relationship quality, and self-esteem in determining life satisfaction. It was hypothesized that maintaining good interpersonal relationships would make individuals in collectivistic cultures not only feel good about their lives but also feel better about themselves. Furthermore, two emotion variables--emotional expression and emotion differentiation--were proposed as possible determinants of relationship quality. It was hypothesized that emotional expressiveness would be more important for maintaining good interpersonal relationships in individualistic societies but emotion differentiation would be more important in collectivistic cultures. These hypotheses were tested with Euro-American, Asian American, Korean, and Chinese groups using multigroup analyses in a structural equation model. Results supported all proposed hypotheses and indicated that emotion differentiation contributes to maintaining good interpersonal relationships in collectivistic cultures, which contributes to self-esteem and satisfaction with life.

Predicting posttraumatic distress in hospitalized trauma survivors with acute injuries.

OBJECTIVE: Each year approximately 2.5 million Americans are hospitalized after sustaining traumatic physical injuries. Few investigations have comprehensively screened for posttraumatic symptomatic distress or identified predictors of posttraumatic stress disorder (PTSD) in representative samples of surgical inpatients. METHOD: The subjects were 101 randomly selected survivors of motor vehicle crashes or assaults who were interviewed while hospitalized and 1, 4, and 12 months after injury. In the surgical ward, inpatients were screened for PTSD, depressive, and dissociative symptoms, for prior trauma, for pre-event functioning, and for alcohol and drug intoxication. Patient demographic and injury characteristics were also recorded. Random coefficient regression models were used to assess the association between these clinical, injury, and demographic characteristics and PTSD symptom levels over the year after the injury. RESULTS: Of the 101 surgical inpatients, 73% screened positive for high levels of symptomatic distress and/or substance intoxication. At 1, 4, and 12 months after the injury, 30%-40% reported symptoms consistent with a diagnosis of PTSD. High ward PTSD symptom levels were the strongest and most parsimonious predictor of persistent symptoms over the course of the year. Greater prior trauma, stimulant intoxication, and female gender were also associated with higher symptom levels. Increasing injury severity, however, was not associated with higher PTSD symptom levels. CONCLUSIONS: Clinical and demographic characteristics readily identifiable at the time of surgical inpatient hospitalization predict PTSD symptoms over the year after injury. Effectiveness trials that test screening and intervention procedures for at-risk inpatients should be developed.
