The repression/suppression of negative emotions has long been considered detrimental for breast cancer (BC) patients, leading to poor coping, progression of symptoms, and general lower quality of life. Therapies have focused on encouraging the expression of negative emotions. While group therapies have proven to be successful for BC patients, no study has looked at the role of expressing negative emotions during the therapeutic interaction. We examined written expressed emotions by women participating in a common form of psychosocial support, Internet based bulletin boards (BBs). Fifty-two new members to BC BBs were studied. They completed measures of quality of life and depression. After 6 months the measures were again assessed and messages during that time were collected and analyzed for emotional content. For the 52 women, results showed that greater expression of anger was associated with higher quality of life and lower depression, while the expression of fear and anxiety was associated with lower quality of life and higher depression. The expression of sadness was unrelated to change scores. Our results serve to challenge the commonly held belief that the expression of all negative emotions are beneficial for BC patients. Instead, expressing specific negative emotions are beneficial, while others are not.
This study tests the causal role of negative self-imagery in social anxiety. Low public-speaking anxious volunteers rehearsed a negative self-image, a positive self-image or a control image prior to giving a speech. As predicted, the negative image group felt more anxious, believed they performed less well and reported more negative thoughts than the positive image group. These findings do not appear to be due to changes in state anxiety, since they remained unchanged when anxiety was controlled in an analysis of covariance. The negative image group also reported more anxiety than the control group. Given that participants do not currently have anxiety problems, the findings are consistent with the idea that negative self-imagery has a causal role in the development and maintenance of social anxiety.
Cardiovascular changes occur during mental stress and in certain types of mood disorders. The neural basis for this phenomenon is unknown but it may be dependent on CNS neurons that provide branched projections to affective processing regions of the brain, such as the medial prefrontal cortex, and to the sympathetic outflow system. Because these putative neurons may be connected to these two target sites by chains of neurons, we performed double virus transneuronal tracing experiments and show here that a select subset of neurons in the medial preoptic nucleus (MPN), lateral hypothalamic area (LHA), and nucleus tractus solitarius (NTS) are co-linked to these two sites. Neurotensin MPN, orexin-containing LHA, and catecholamine NTS neurons were the major phenotypes involved in these projections. This novel class of neurons may coordinate cardiovascular changes seen in different emotional states.
