Illness perceptions and beliefs about medication: impact on health-related quality of life in adolescent kidney transplant recipients

The concept of treatment beliefs in children and adolescents with chronic health conditions: a scoping review

Children and adolescents with chronic health conditions are faced with ongoing challenges, making self-regulation crucial. As children grow up, they gradually develop differentiated beliefs about illness and treatment. While research indicates treatment beliefs as relevant factor on outcomes like adherence, the specific contents and dimensions of children's and adolescents' treatment beliefs remained unclear. This scoping review therefore aimed at the identification of treatment beliefs dimensions in children and adolescents with chronic health conditions, the underlying theoretical frameworks, and methodological operationalisation. Published literature was examined by applying systematic searches in electronic databases (Medline, PsycINFO, CINAHL) and comprehensive selection criteria, resulting in 49 included studies. The predominant treatment beliefs dimensions were necessity, concerns, perceived benefits and costs/barriers, and expectations. The latter can be differentiated into outcome, social, process, and structural expectations, and expectations of one's own role in the treatment process. In addition, dimensions that cover emotions and reasons for treatment were identified. The results are related to the methods and theoretical models applied, which were often adapted from adult research. However, additional and possibly more child-specific dimensions such as social expectations and emotions were found. This scoping review indicates several research gaps and discusses practical implications.

Family Environment, Social Support, and Health-Related Quality of Life in Adolescents Following Kidney Transplant

BACKGROUND

Kidney transplantation is the treatment of choice for pediatric end-stage renal disease. Transplant recipients often have better neurocognitive, academic, and health-related outcomes. While there is some evidence that health-related quality of life (HRQOL) improves following kidney transplant, other studies have found adolescent transplant recipients report lower overall HRQOL than healthy peers. Current research has focused on individual-level factors affecting adjustment to organ transplant, warranting examination of HRQOL from a systems perspective. Family environment and social support contribute to a system of proximal relationships that are crucial in adolescents' development, making them important factors to study in relation to HRQOL post-transplant.

METHODS

The current study utilized archival data of adolescent renal transplant patients who completed surveys about their family environment, social support, and HRQOL during routine transplant clinic visits.

RESULTS

Family cohesion, as well as social support from parents, classmates, and people in school, were positively correlated with HRQOL. Social support from people in school uniquely predicted variance in HRQOL, beyond the contribution of overall family environment after controlling for demographic factors. Relative to comparable adolescent samples, transplant recipients reported more optimal overall family environment, greater social support from teachers, and lower social support from close friends.

CONCLUSION

Psychosocial interventions for adolescent kidney transplant recipients may be enhanced by collaborating with school professionals and further bolstering strengths in the family environment. Kidney transplant recipients may benefit from long-term intervention, as decreased HRQOL appears to persist years post-transplant.

The rehabilitation treatment beliefs questionnaire-revised: assessing adolescents' treatment beliefs

OBJECTIVE

While there are several studies on children's and adolescents' beliefs about illness and medication treatment, there is limited research on their treatment beliefs in the context of rehabilitation. The Rehabilitation Treatment Beliefs Questionnaire (RTBQ) was the first instrument available to assess pediatric patients' rehabilitation-related treatment beliefs. However, the RTBQ had some limitations that we aimed to address in this study: We revised the content of the RTBQ to include previously unaddressed dimensions of rehabilitation-related treatment beliefs, and we thoroughly tested its psychometric properties based on a sizeable, multicenter sample of adolescents with different chronic diseases.

METHODS

Across 11 pediatric rehabilitation clinics throughout Germany, eligible patients aged 12-18 years with any chronic physical or mental health condition were invited to participate in an online survey. Psychometric evaluation included item analysis, exploratory factor analysis, internal consistency and construct validity.

RESULTS

The sample comprised N = 294 adolescents (M = 14.2 years) with various chronic conditions. Psychometric testing demonstrated a coherent factor structure with 6 interpretable scales covering process and outcome expectations, expectations of one's own role in the treatment process, structural expectations, concerns, and emotions, the latter three representing previously unaddressed dimensions of rehabilitation-related treatment beliefs. Internal consistency was acceptable to good. Construct validity analyses showed mostly hypotheses-consistent correlations with related constructs.

CONCLUSIONS

The revised RTBQ provides a psychometrically well-tested, adolescent-specific, and disease-generic instrument that captures multiple dimensions of rehabilitation-related treatment beliefs. Practical implications include identifying adolescents' beliefs about rehabilitation treatment in order to actively involve them in their illness management.

Kidney Transplantation Improves Health-Related Quality of Life in Older Recipients

Kidney transplantation is the best treatment for kidney failure in older patients. However, little is known regarding changes in health-related quality of life (HRQoL) from before to after transplantation and determinants of HRQoL in older kidney transplant recipients (KTR). We studied both, using data of older (≥65 years) patients waitlisted for kidney transplantation and older KTR 1 year after transplantation from the TransplantLines Biobank and Cohort Study. HRQoL was assessed using the SF-36 questionnaire. We included 145 older waitlisted patients (68% male, age 70 ± 4 years) and 115 older KTR at 1 year after transplantation (73% male, age 70 ± 4 years). Both mental (48.5 ± 8.4 versus 51.2 ± 7.7, p = 0.009) and physical (47.4 ± 8.5 versus 52.1 ± 7.2, p < 0.001) HRQoL were higher among included KTR, compared to the waitlisted patients. In paired analyses among 46 patients with HRQoL-data both before and after transplantation, there was a trend towards increased mental HRQoL (49.1 ± 8.4 to 51.6 ± 7.5, p = 0.054), and significantly increased physical HRQoL (48.1 ± 8.0 to 52.4 ± 6.7, p = 0.001) after transplantation. Among all assessed factors, the number of patient-reported immunosuppressive drug-related side effects was most strongly negatively associated with both mental and physical HRQoL. In conclusion, HRQoL is significantly higher among older KTR after kidney transplantation compared to older waitlisted patients.

Social support mediates the relationship between illness perception and psychosocial adaptation among young and middle-aged kidney transplant recipients in China

Background

No research has yet been done on social support's influence on the association between illness perception and psychosocial adaptation among young and middle-aged kidney transplant recipients in China. Accordingly, it remains unclear how medical personnel can assist patients in successfully adjusting to the early postoperative period and improving their health.

Objective

This study sought to explore the influence of illness perception and social support on the psychosocial adaptation of young and middle-aged recipients of kidney transplants in China during the early postoperative period.

Methods

This study adopted a cross-sectional design. The study included 236 young and middle-aged kidney transplant recipients from a tertiary hospital in China. Demographic and disease-related data were collected. Additionally, the Psychosocial Adjustment to Illness Scale-Self-Report, the Brief Illness Perception Questionnaire, and the Multidimensional Scale of Perceived Social Support were used to assess participants' psychosocial adaptation, illness perception, and social support, respectively. The model was examined using descriptive analysis, Pearson's correlation analysis, hierarchical multiple regression analysis, and the PROCESS Macro in SPSS 26.0.

Results

A total of 176 (74.56%) participants reported an average psychosocial adaptation score >50, which is relatively negative. Marital status, education level, residence, per capita monthly income (in Chinese yuan), medical insurance, work status, post-transplant time, body mass index, creatinine status, and complications were all related to psychosocial adaptation (p < 0.05). The more negative their illness perception and the worse their social support, the worse the psychosocial adaptation of young and middle-aged kidney transplant recipients. Further, the effect of illness perception on psychosocial adaptation was partially mediated by social support (36.56%).

Conclusion

In general, the psychosocial adaption level of young and middle-aged kidney transplant recipients was negative during the early postoperative period. Healthcare teams should assist patients in building a positive illness perception shortly following kidney transplantation, while also providing psychological care and support to help them cope with the onset of psychosocial issues.

Group-based trajectory modeling to identify health beliefs of COVID-19 vaccination and its predictors: A cohort study in China

OBJECTIVES

This study aimed to characterize distinct patterns of change in health beliefs and their dimensions of COVID-19 vaccination and to evaluate the predictors of various trajectory groups.

METHODS

A total of 1129 participants who completed two doses of COVID-19 vaccines in China were included in this prospective study. Participants' characteristics and health beliefs regarding COVID-19 vaccination were collected before and after the two doses of COVID-19 vaccination. A group-based trajectory model was used to identify the distinct longitudinal patterns of health beliefs and their dimensions. A multinomial logistic regression model was conducted to determine the predictors of different trajectory groups.

RESULTS

The group-based trajectory model identified two to four distinct patterns of global health beliefs and their domains, namely, very low-stable (16.1%), low-stable (30.2%), medium-stable (45.6%), and high-stable (8.1%) trajectories for global health beliefs. And the five domains of health beliefs showed two or three trajectory stable progression, which were similar to the global health beliefs trajectories. Sex, occupation post, adverse reactions foreboding, and quality of life were associated with the trajectory of global health beliefs or at least one domain of health beliefs.

CONCLUSIONS

During the study, individuals' health beliefs about COVID-19 vaccination were stable without the interference of external factors. Based on the impact of sex, occupation post, adverse reactions foreboding, and quality of life on individuals' health beliefs, personalized interventions can be developed to improve public health beliefs about COVID-19 vaccination and reduce vaccination hesitancy.

The psychosocial needs of adolescent and young adult kidney transplant recipients, and associated interventions: a scoping review

BACKGROUND

Renal transplantation is considered the gold standard treatment for end-stage kidney disease. Adolescent and young adult kidney transplant recipients have the highest rate of graft loss amongst transplanted patients. It is largely accepted this is due to psychosocial and behavioural difficulties, which impact adherence to prescribed therapies. This phenomenon is not isolated to a particular healthcare system having been observed in multiple countries across different continents. It is a global issue of concern. We sought to review the psychosocial needs of these patients, and the interventions designed to meet these needs.

METHODS

A scoping review was conducted based on Arksey and O'Malley's six-stage framework. Eligibility criteria included primary studies of any type that investigated the psychosocial needs of adolescent and/or young adult renal transplant recipients or studies which examined interventions designed to address these needs. Search strategies were developed and conducted on PsycINFO, PubMed, Embase, and CINAHL. Articles meeting the inclusion criteria were critically reviewed using a descriptive-analytical narrative method.

RESULTS

Thirty-nine studies met our inclusion criteria, 30 of which related to psychosocial needs, and the remainder examined psychosocial interventions. Four main themes were derived from our analysis of psychosocial needs literature, as follows: the need for (1) emotional support, (2) acceptance, (3) direction, (4) equality in healthcare. 2 main themes emerged from analysis of psychosocial intervention literature, namely: psychosocial (1) capability, (2) assessment. Despite the evidence that graft health is strongly associated with psychosocial wellbeing, findings revealed a significant lack of literature investigating how best to meet psychosocial needs. Trends were observed amongst intervention studies, namely interventions of novel and non-evidenced based design, with the aim of improving medication adherence through organisational strategies and education. However, literature regarding psychosocial needs showed non-adherence to therapies was not simply a result of disorganisation or lack of understanding, but rather, was founded on a recipient's idiosyncratic relationship with their prescribed therapies e.g., psychological, social or financial reasons for non-adherence.

CONCLUSIONS

Future research should be directed at investigating the efficacy of evidence-based interventions that empower the individual patient to overcome their specific barrier to an optimal relationship with their therapies.

Illness perceptions and health-related quality of life in individuals with overweight and obesity

INTRODUCTION

To understand how individuals (self-)manage obesity, insight is needed into how patients perceive their condition and how this perception translates into health outcomes (e.g., health-related quality of life, HRQOL). Our objectives were (1) to examine illness perceptions in individuals with overweight and obesity, and (2) to investigate associations of these perceptions with physical and mental HRQOL.

METHODS

In a cross-sectional analysis of the Netherlands Epidemiology of Obesity Study (n = 6432; 52% women), illness perceptions were assessed using the Brief Illness Perception Questionnaire, and HRQOL was assessed using the 36-Item Short-Form Health Survey. Illness perceptions were calculated for different categories of overall, abdominal, and metabolically unhealthy obesity. We investigated associations of illness perceptions with HRQOL using BMI-stratified multivariable linear regression analyses.

RESULTS

Compared to individuals with normal weight, individuals with obesity believed to a higher extent that their condition had more serious consequences [Mean Difference (95%CI): 1.8 (1.6-2.0)], persisted for a longer time [3.4 (3.2-3.6)], manifested in more symptoms [3.8 (3.6-4.0)], caused more worry [4.2 (3.9-4.4)] and emotional distress [2.0 (1.8-2.2)], but was more manageable with medical treatment [3.1 (2.9-3.4)]. They perceived to a lesser extent that they had personal control [-2.2 (-2.4, -2.0)] and understanding [-0.3 (-0.5, -0.1)] regarding their condition. These negative perceptions were less pronounced in individuals with abdominal obesity. Behaviour/Lifestyle was attributed by 73% of participants to be the cause of their obesity. Stronger negative illness perceptions were associated with impaired HRQOL, particularly the physical component.

CONCLUSION

Individuals with obesity perceived their conditions as threatening, and this seemed somewhat stronger in individuals with overall obesity than those with abdominal obesity. Behaviour/Lifestyle is a crucial target intervention and empowering self-management behaviour to achieve a healthy body weight may deliver promising results. In addition, strategies that aim to change negative perceptions of obesity into more adaptive ones may improve HRQOL.
