Fifty-three breast cancer patients completed an Internet-based diary measuring daily negative affect and positive affect and daily negative and positive events for seven consecutive evenings shortly after surgery. The authors used Hierarchical Linear Modeling (Raudenbush and Bryk in Hierarchical linear models: applications and data analysis methods. Sage, Thousand Oaks, CA, 2002) to examine moderators of affective differentiation, or the daily relationship between the patients' negative affect and positive affect. Strong affective differentiation is characterized by the relative independence of negative and positive affect. There were no significant Level 1 (within-subject) moderators of affective differentiation. However, at Level 2 (between-subject), as predicted, increased age was associated with stronger affective differentiation, as was greater use of planning to cope with breast cancer. Also as predicted, increased anxiety and greater use of behavioral disengagement and denial coping were associated with weaker affective differentiation. The results suggest the value of the affective differentiation construct, and a daily diary methodology, for research on the daily lives of breast cancer patients.

    • "In particular, our samples were largely comprised of Caucasian college students, and the results may not generalize to other populations. The restricted age range is also relevant considering that some studies have found that affective differentiation increases with age (Carstensen et al., 2000; Dasch et al., 2010). Finally, our measures of PA and NA assessed emotion over the preceding few hours in Study 1 (as compared to ''current mood'' in Studies 2 and 3), which does not necessarily capture the experience of those emotions simultaneously.

    ABSTRACT: Affective differentiation is the degree to which positive affect (PA) and negative affect (NA) are uncorrelated. The dynamic model of affect (Zautra, Potter, & Reich, 1997) posits that the link between PA and NA should be stronger when stress is high. Because neuroticism relates to more negative everyday stress perceptions and therefore higher daily stress, we hypothesized that neuroticism should be associated with lower affective differentiation on a daily basis. We examined how neuroticism impacts momentary affective differentiation in undergraduate students (n = 126) using an experience sampling design with mood monitored four times daily for one week. We found that neuroticism moderates the within-person relationship between PA and NA: those who are higher in neuroticism experience less affective differentiation. This effect was not mediated or moderated by recent major life stress. We replicated the main finding in two subsequent samples (n = 102 and n = 120, respectively), and thus present the first large set of studies to demonstrate consistently that neuroticism moderates the within-person link between PA and NA.

    ABSTRACT: Aim The international literature rarely concerns itself with the refusal of treatment. We have studied the adaptation and subconscious defence mechanisms triggered in patients at the time of proposing adjuvant chemotherapy after cancer surgery. Materials and methods This longitudinal clinical study based on 50 breast cancer patients compares the psychological factors involved in the making of decisions following oncological consultation. Results Eighty-two percent of patients accepted chemotherapy while 18% refused it. The Accepting group usually exhibits depression in its reaction whereas the Refusing group generally has more hostile traits. Anxiety, significantly higher in the Accepting group than in the Refusing group, seems to be linked to feelings that are repressed by the patient that submits to the medical advice. Conversely, patients refusing the treatment tend to exhibit their hostility towards doctors and medicine verbally. Conclusion Changes in doctor- patient communication, coupled with a greater knowledge of the personality of patients, may help encourage patients to accept the treatment offered to them.
