The experience of being diagnosed with and treated for cancer is an extremely stressful experience for most individuals. Historically, the literature on stress and coping has focused on negative outcomes, such as depression and anxiety, in relation to one‘s experience with cancer. Under-represented in the literature has been a theoretical framework that examines positive and transformative experiences that may occur throughout the cancer experience. The current study assessed interpersonal variables that rarely have been investigated in relation to one‘s experience with cancer (i.e., received social support and unsupportive interactions) and their association with depressive symptoms, positive emotion, and posttraumatic growth in a sample of men and women recently diagnosed with cancer. The main research design was cross-sectional (although longitudinal analyses were conducted on an exploratory basis), and self-report data were collected from 60 participants who had been diagnosed with cancer on average 5.68 months prior to data collection. Contrary to hypotheses, hierarchical regression equations indicated that received social support was not related to any of the outcome variables. However, unsupportive responses from a main support person were found to be significantly and positively related to participants‘ reports of depressive symptoms and posttraumatic growth within the context of their cancer experience. A major contribution of the present study is that it called attention to the importance of studying unsupportive interactions separately from social support. Moreover, this is the first study to investigate the relationship between unsupportive interactions and posttraumatic growth in a sample of recently diagnosed cancer patients. Findings were surprising in that the more unsupportive responses individuals with cancer received from a main support person, the more personal growth they reported. The results from the present study have important research and clinical implications for understanding the relationship between unsupportive interactions and posttraumatic growth among men and women who have been diagnosed with cancer.

The objective of this study was to investigate the association between both social support and unsupportive interactions and psychological outcomes, in a sample of college students who recently had experienced a stressful event. The research design was cross-sectional, and data were collected from 142 college students. As hypothesized, a significant positive association was found between unsupportive interactions received by participants and depressive symptoms. Contrary to hypotheses, no significant associations were found between unsupportive interactions and positive emotion or posttraumatic growth. Additionally, no significant relationship was evident between received emotional support and the outcome variables. Exploratory analysis revealed that positive reappraisal mediated the relationship between total received support and posttraumatic growth. A major contribution of the present study is evidence for unsupportive interactions significantly predicting depressive symptoms in a college-aged sample. Additionally, the current study adds to the literature concerning the correlates of posttraumatic growth.

Heart rate variability (HRV), a physiological marker of autonomic nervous system (ANS) engagement, has been associated with a wide variety of clinical and psychological processes. High frequency (HF) HRV power, specifically, has been linked with the parasympathetic nervous system (PNS) and self-regulation. The current inquiry used a random effects growth model to study the HF HRV response to an emotional task and to predict individual differences in HF HRV as a function of trait hostility, neuroticism, and emotion regulation strategies (e.g., positive reappraisal, positive refocusing). Results indicated that the task engaged both branches of the ANS. HF HRV was not related to either hostility or neuroticism. However, positive reappraisal was associated with both high baseline values of HF HRV (i.e., greater initial parasympathetic activation) and lower rates of reactivity (i.e., less parasympathetic withdrawal). Overall, these results add to the evidence that positive reappraisal is a powerful component of emotion regulation and may be an important intervention target.
