Adolescents’ and Parents’ Experiences of Managing the Psychosocial Impact of Appearance Change During Cancer Treatment

Heidi Williamson; Diana Harcourt; Emma Halliwell; Hannah Frith; Melissa Wallace

Using combined qualitative data from multiple case study interviews and an online survey, this study explored the impact of appearance change on 22 adolescents receiving cancer treatment aged 13 to 18 years and six of their parents. Data were analyzed using template analysis. Appearance changes were a major concern. Adolescents typically struggled to adapt to new experiences and concerns related to this highly sensitive issue. Many felt anxious and self-conscious and were reluctant to reveal appearance changes in public. These feelings were compounded by the negative reactions of others (e.g., staring, teasing, and inappropriate questioning), which sometimes lead to avoidance of social activity and threats of noncompliance. Parents of these children felt ill-prepared to manage appearance-related anxieties. Adolescents wanted support to develop the practical and social skills necessary to maintain a “normal” appearance and manage the negative responses of others. However, some adolescents showed resilience and, with support from friends and family, developed strategies to manage their altered appearance and its social consequences. These strategies are explored, which can inform interventions to support adolescents and parents.

Genetic testing for BRCA1/2 mutations associated with hereditary breast and ovarian cancer reveals significant risk information about ones chances of developing cancer. It is important to study communication processes in families where members are undergoing genetic testing because the information received is crucial not just to the individual concerned but also to other members of the biological family. This study investigates family communication of BRCA1/2 test results from both the informants’ and recipients’ perspectives. A total of 10 female patients and 22 of their relatives were interviewed. Patients’ and their relatives described feelings of responsibility for sharing genetic information within the family to enable others to reduce their risks of developing cancer. However, there were limits to an individuals’ responsibility once key family members had been informed, who then had to take responsibility for continuing dissemination of information. Whilst there was an implicit responsibility to inform the family of a mutation, information was edited or withheld in the best interest of relatives, dependent upon their perceived emotional readiness, resilience and current life stage and circumstances. The pre-existing family culture and the impact previous cancer diagnoses had upon the family also influenced the process of communication. Findings are discussed in relation to extant literature and implications for clinical practice are considered.

Genetic testing for hereditary breast and ovarian cancer reveals significant risk information regarding ones chances of developing cancer that has potential implications for patients and their families. This study reports on the motivations and attitudes of index patients and their relatives towards genetic testing for hereditary breast and ovarian cancer. In total, 10 female index patients and 20 of their relatives were interviewed regarding their experiences of communicating genetic information within their families, and their motivations and attitudes towards genetic testing. The analysis found two types of ‘family groups’: groups strongly committed to genetic testing and groups uncertain about testing. Within committed family groups, index patients and their relatives felt obliged to be tested for others, leading some relatives to be tested without having fully thought through their decision or the implications of knowing their mutation status. These family groups also described considerations in relation to the value of testing for themselves. In family groups uncertain about testing, relatives had not attended for predictive testing, had postponed decision making until some point in the future or had expressed ambivalence about the value of testing for themselves. Results suggest the value of explicitly acknowledging motivations for genetic testing within the context of family obligations, relationships and communication, and the possible value of involving family members in genetic counselling and decision making from a familys first contact with genetic services.

Building our youth for the future

Linda-Gail Bekker; Leigh F. Johnson; Melissa Wallace; Sybil Hosek

Adolescents and young adults are at increased risk for HIV due to the many developmental, psychological, social, and structural transitions that converge in this period of the lifespan. In addition, adolescent deaths resulting from HIV continue to rise despite declines in other age groups. There are also young key populations (YKPs) that bear disproportionate burdens of HIV and are the most vulnerable, including young men who have sex with men (MSM), transgender youth, young people who inject drugs, and adolescent and young adult sex workers. As a society, we must do more to stop new HIV infections and untimely HIV‐related deaths through both primary and secondary prevention and better management approaches. Using an interwoven prevention and treatment cascade approach, the starting point for all interventions must be HIV counselling and testing. Subsequent interventions for both HIV‐negative and HIV‐positive youth must be “adolescent‐centred,” occur within the socio‐ecological context of young people and take advantage of the innovations and technologies that youth have easily incorporated into their daily lives. In order to achieve the global goals of zero infections, zero discrimination and zero deaths, a sustained focus on HIV research, policy and advocacy for YKPs must occur.

Background In South Africa, the prevalence of oncogenic Human Papillomavirus (HPV) may be as high as 64%, and cervical cancer is the leading cause of cancer-related death among women. The development of efficacious prophylactic vaccines has provided an opportunity for primary prevention. Given the importance of psycho-social forces in vaccine uptake, we sought to elucidate factors influencing HPV vaccination among a sample of low-income South African adolescents receiving the vaccine for the first time in Soweto. Methods The HPV vaccine was introduced to adolescents in low-income townships throughout South Africa as part of a nationwide trial to understand adolescent involvement in future vaccine research targeting human immunodeficiency virus (HIV). We performed in-depth semi-structured interviews with purposively-sampled adolescents and their care providers to understand what forces shaped HPV vaccine uptake. Interviews were recorded, transcribed, translated, and examined using thematic analysis. Results Of 224 adolescents recruited, 201 initiated the vaccine; 192 (95.5%) received a second immunization; and 164 (81.6%) completed three doses. In our qualitative study of 39 adolescent-caregiver dyads, we found that factors driving vaccine uptake reflected a socio-cultural backdrop of high HIV endemnicity, sexual violence, poverty, and an abundance of female-headed households. Adolescents exercised a high level of autonomy and often initiated decision-making. Healthcare providers and peers provided support and guidance that was absent at home. The impact of the HIV epidemic on decision-making was substantial, leading participants to mistakenly conflate HPV and HIV. Conclusions In a setting of perceived rampant sexual violence and epidemic levels of HIV, adolescents and caregivers sought to decrease harm by seeking a vaccine targeting a sexually transmitted infection (STI). Despite careful consenting, there was confusion regarding the vaccine’s target. Future interventions promoting STI vaccines will need to provide substantial information for participants, particularly adolescents who may exercise a significant level of autonomy in decision-making.

Community engagement and investment in biomedical HIV prevention research for youth: rationale, challenges, and approaches.

Jonathan M. Ellen; Melissa Wallace; Fredrick Sawe; Kevin Fisher

There has been a growing awareness of the importance of engaging communities in the development, testing, and eventual dissemination of biomedical strategies. Community engagement offers many benefits but comes with many challenges. This article will discuss these benefits and challenges and describe two examples of community engagement, Connect to Protect® in the United States, and the South African Studies on HIV in Adolescents Project in South Africa, that represent investment in community engagement as preparation for biomedical HIV prevention clinical trials for youth.

The Development of a Methodology for Examining the Process of Family Communication of Genetic Test Results

Jonathan A. Smith; Caroline Dancyger; Melissa Wallace; Chris Jacobs; Susan Michie

It is important to study communication processes in families where members are undergoing testing for genetic conditions because the information received from such testing is crucial not just to the individual concerned but also to other members of the biological family. This topic has received little research attention, in part because of the complexities of methodology required. In this paper we present the development of a method specifically designed for the examination of the content and process of communication of genetic information in families. The method aims to maximize ecological validity as far as is possible. We describe how participants and other family members are recruited and how data were collected. We outline three main data analytic strategies: a graphic to show how genetic information changes as it flows from clinic and through the family, an intensive qualitative analysis of the meaning and impact of the genetic information to different family members, and an informative genogram which plots key family dynamics. This method will be illustrated in relation to a study of ten family-groups where one individual has been found to carry a genetic mutation predisposing them to hereditary breast and ovarian cancer.

Adjustment to appearance changes resulting from meningococcal septicaemia during adolescence: A qualitative study

Melissa Wallace; Diana Harcourt; Nichola Rumsey

Statement of purpose: Meningococcal Septicaemia (ms) is an acute, life-threatening illness characterized by rapid progression and if not treated swiftly can result in death within hours. Those who survive may require skin grafting or amputation of digits and limbs, and be left with severe scarring. Despite the trauma associated with ms, surprisingly little research has been conducted to determine its psychosocial impact. This study therefore explored the impact of ms during adolescence, with an emphasis on adjustment to a permanently altered appearance following a life-threatening illness. Methods used: Eleven in-depth, semi-structured interviews were conducted with adolescents (7 female) and analysed using Interpretative Phenomenological Analysis (IPA). Results: Interviews highlighted the life-altering nature of the experience and the impact this had on finding meaning, life evaluation and adjustment to an altered appearance. Participants spoke at length about differences in themselves, ‘pre and post ms’, how they assimilated their altered self into life after ms, and the symbolisation attributed to their scars. Issues relating to healthcare provision also arose as a significant theme. Discussion: Participants demonstrated a high degree of resilience in response to their experiences. The means by which this has been achieved, including social comparison are examined in detail and offer a fertile area for further research.

BACKGROUND The epidemiology and impact of multiple concurrent Human papillomavirus (HPV) infections on the natural history of cervical disease is uncertain, but could have significant implications for cervical cancer prevention and HPV vaccination strategies. METHODS A cross-sectional prevalence study was conducted to determine the overall prevalence of HPV and the rate of multiple concurrent HPV infections, in a cohort of sexually active HIV-uninfected South African adolescents. HPV genotyping was performed using the polymerase chain reaction. RESULTS Overall prevalence of HPV was 64.1%. Multiple concurrent HPV infections were found in 43.6% of participants and 68% of HPV-infected participants. Non-vaccine high-risk HPV (HR-HPV) genotypes were found much more often than vaccine types (HPV16 and HPV18). CONCLUSIONS Our cohort of young South African females was found to have a high overall prevalence of HPV and multiple concurrent HPV infections. Most HR-HPV infections found were genotypes other than HPV16 or HPV18.

Background. HIV-infected adolescents may be at higher risk for high-grade cervical lesions than HIV-uninfected adolescents. The purpose of this study was to compare the prevalence of high-risk HPV (HR-HPV) infections and Pap smear abnormalities between these two groups. Methods. In this cross-sectional study, we compared the HPV DNA and Pap smear results between 35 HIV-infected and 50 HIV-uninfected adolescents in order to determine the prevalence of HR-HPV genotypes and cervical cytological abnormalities. Comparisons were made using Pearson χ 2 and independent-samples t-tests analyses, and associations between demographic and behavioral characteristics and HPV infections were examined. Results. HIV-infected participants were more likely to be infected with any HPV (88.6% versus 48.0%; P < 0.001) and with at least one HR-HPV (60.0% versus 24.0%; P = 0.001), and to have multiple concurrent HPV infections (68.6% versus 22.0%; P < 0.001). HPV 16 and 18 were relatively underrepresented among HR-HPV infections. Abnormal Pap test results were more common among HIV-infected participants (28.8% versus 12.0%; P = 0.054). A history of smoking was associated with HR-HPV infection. Conclusions. HIV-infected adolescents have an increased risk of infection with HR-HPV and of Pap test abnormalities. The majority of HR-HPV infections among our participants would not be prevented by the currently available vaccinations against HPV.
