Cross-situational emotionality is a well-established dimension of personality, however the ability to modulate emotional expression by social domain is also a key aspect of personality functioning. We describe a self-report measure, the Domain Emotional Expression Profile (DEEP), designed to assess 5 emotions and behaviours in relation to 5 social domains, and report 2 studies. Study 1 (N = 166 students) assessed construct validity based on predictions from attachment theory regarding distress expression, and explored other emotions and domains. Study 2 (N = 279 students) tested hypotheses based on findings from Study 1 and explored the status of friendship interactions. In Study 1, mean distress-expression comfort-seeking scores in family and partner interactions were substantially higher than in work and in a social (e.g. party) situation consistent with the attachment based prediction (p < .001). In exploratory analyses mean anger expression scores were similarly higher in family and partner relationships than in work and social situations. However distress expression was higher in partner than family interactions (p = .008) which was not the case for anger expression. Study 2 replicated these findings from Study 1, and indicated an intermediate position for friendships between family and partner, and work and social interactions. We report support for the construct validity of the DEEP and replicated evidence regarding the partitioning of anger expression across domains, together with new indications of friendship processes. This method of profiling emotional expression and behaviours across social contexts offers a way of characterising individual differences, including those associated with psychopathology.
