The role of hurtful and healing messages on eating disorder symptomology and recovery     

Victoria Orrego Dunleavy  Ekaterina Malova 《Qualitative Research Reports in Communication》2019,20(1):58-66

This study analyzed how clinically diagnosed women with eating disorders described the hurtful messages from parents, siblings, and peers that triggered eating disorder symptomology as well as the healing messages that assisted with coping and recovery. Three themes overlapping across all groups were revealed for hurtful messages: 1) critical, 2) social modeling, and 3) direct comparison. Our findings show that fathers, siblings, and peers similarly used teasing. Other points of distinction were uncovered for fathers: aggressive messages and denial of eating disorder. Competition with female siblings and friends was also a triggering factor for young females with eating disorders. Four distinct categories of healing messages were identified: 1) emotional, 2) instrumental, 3) informational, and 4) appraisal. Point of distinction for friends’ and siblings’ healing messages was absence of negative comments about weight and appearance. Results were able to encapsulate both helpful/supportive and hurtful/unsupportive messages, and these findings will be helpful for treatment centers who may incorporate them in recovery programs.  相似文献

The Relationship Between Social Support and Type 2 Diabetes Risk     

Kristin G. Maki 《Communication Research Reports》2018,35(1):12-21

Prior research links social support with several positive health outcomes. However, less is known about the association between social support and Type 2 diabetes risk factors, such as glycemic control. This study uses a nationally representative sample from the National Longitudinal Study of Adolescent to Adult Health (Add Health) to examine the relationship between social support and glycated hemoglobin A1c (HbA1c) levels. The data were analyzed through hierarchical logistic regression. Results indicate an inverse relationship between elevated HbA1c levels and individuals’ satisfaction with their partners’ daily interactions. Implications include the possibility of reducing Type 2 diabetes risk through communication interventions highlighting the importance of maintaining positive daily interactions.  相似文献   

A Replication of Xu & Burleson (2001) “Effects of Sex,Culture, and Support Type on Perceptions of Spousal Social Support: An Assessment of the ‘Support Gap’ Hypothesis in Early Marriage”     

Meara H. Faw  Jacquelyn Harvey  Hairong Feng 《Communication Studies》2018,69(3):314-325

In response to recent calls regarding the social sciences’ “replication crisis,” we have endeavored to replicate Xu and Burleson’s (2001) research study, “Effects of Sex, Culture, and Support Type of Perceptions of Spousal Support: An Assessment.” This study, which examines the support gap hypothesis and its different manifestations among men and women from the United States of America and China, has contributed greatly to scholarly conversations on social support, sex, culture, and support gaps. Results from our study partially replicate Xu and Burleson’s (2001) original findings and provide general empirical evidence for the support gap hypothesis. Differences in findings between the two studies and their implications are discussed.  相似文献   

Living with a rare health condition: the influence of a support community and public stigma on communication,stress, and available support     

Xun Zhu  Rachel A. Smith  Roxanne L. Parrott 《Journal of Applied Communication Research》2017,45(2):179-198

People affected by rare diseases often have limited coping resources and sometimes face stigma. They build communities with others who share their conditions, but not all members may benefit from these communities. This study investigated how adults with a rare genetic health condition (Alpha-1 antitrypsin deficiency; AATD) think about both the Alpha-1 community and public stigma about AATD, and how these cognitions predict their communication responses and well-being. The results showed that people with AATD-encountered stigmatization from various sources. Stronger public stigma predicted more secrecy, more stress, and less available support. Stronger group identification with the Alpha-1 community predicted less secrecy; stronger group activism predicted more available support and more communication to challenge stigmatizers. Post hoc analyses showed significant interactions between public stigma and group cognitions on communication to challenge stigmatizers. Practical implications for bolstering communities to improve the well-being of people with rare diseases were discussed.  相似文献   

Relational Maintenance and Social Support in the Aftermath of Sudden and Expected Death     

Jonathon K. Frost  James M. Honeycutt  Stephanie K. Heath 《Communication Research Reports》2017,34(4):326-334

Bereavement is a state of grieving after the loss of a loved one. Past research has suggested that bereavement is particularly challenging, both physically and emotionally, in the aftermath of unexpected death. Here, we examine bereavement in which death occurred suddenly, compared to a chronic condition where death was expected, in terms of perceived social support and relational maintenance with the deceased in the form of imagined interactions and social media interactions. Results indicated that individuals experiencing sudden death bereavement were more likely to engage in both postmortem relational maintenance techniques and perceived less social support than individuals in the expected death bereavement group. Results are discussed in terms of previous findings.  相似文献   

Anonymity and Interaction in an Online Breast Cancer Social Support Group     

Katie K. Kang 《Communication Studies》2017,68(4):403-421

Despite the benefits of using online social support groups, prior research does not provide a solid understanding of the online factors related to an individual’s supportive interaction. Accordingly, this study aims to explore how various aspects of anonymity predict different levels of social support engagement. The current study uncovers that visually identifiable group members are more likely to get supportive responses than are visually anonymous members. Also, when support group members are visually and discursively identifiable, they are more likely to get supportive messages than those who are visually and discursively anonymous. Additionally, the more identifiable support group members are, the more they receive positive messages. Practical implications for the role of social support group members’ anonymity/identifiability on the overall social support process are presented.  相似文献
