Illness perceptions as a mediator between emotional distress and management self-efficacy among Chinese Americans with type 2 diabetes

Preliminary Validation of the Revised Illness Perception Questionnaire for Patients with Nasopharyngeal Carcinoma in China

Nasopharyngeal carcinoma is a common and highly malignant cancer in southern China. It is important to accurately assess the illness perception of nasopharyngeal carcinoma according to the common-sense model of self-regulation. The purpose was to validate the Chinese version of the Revised Illness Perception Questionnaire for patients with Nasopharyngeal carcinoma. A cross-sectional survey of 631 patients with Nasopharyngeal carcinoma was conducted in Guangzhou, China. The reliability of the scale was evaluated using Cronbach's alpha. The factor structure was assessed using exploratory factor analysis (EFA) of each dimension. The EFA revealed that the 29-item self-rated scale has a seven-factor structure consistent with the original scale and explained 67.3% of the variance after extraction and rotation. The scale showed satisfactory reliability. The item-total correlations ranged from -0.16 to 0.64 (p < 0.05). The item-subscale correlations ranged from 0.46 to 0.91 (p < 0.05). The item-other subscale correlations ranged from -0.38 to 0.51 and from -0.21 to 0.56 (p < 0.05). Significant correlations were found between the timeline (acute/chronic) (r = 0.224, r = 0.166), consequences (r = 0.415, r = 0.338), timeline cyclical (r = 0.366, r = 0.284), emotional representations (r = 0.497, r = 0.465), personal control (r = -0.122, r = -0.134), treatment control (r = -0.135, r = -0.148), and illness coherence (r = -0.261, r = -0.213) subscales, and depression, anxiety (p < 0.05). The scale revealed acceptable reliability, factorial validity, and construct validity. It could be used to assess the illness representations of Chinese patients with nasopharyngeal carcinoma.

The relationship between patient empowerment and related constructs, affective symptoms and quality of life in patients with type 2 diabetes: a systematic review and meta-analysis

Introduction

The aim of this systematic review is to assess the relationship between patient empowerment and other empowerment-related constructs, and affective symptoms and quality of life in patients with type 2 diabetes.

Methods

A systematic review of the literature was conducted, according to the PRISMA guidelines. Studies addressing adult patients with type 2 diabetes and reporting the association between empowerment-related constructs and subjective measures of anxiety, depression and distress, as well as self-reported quality of life were included. The following electronic databases were consulted from inception to July 2022: Medline, Embase, PsycINFO, and Cochrane Library. The methodological quality of the included studies was analyzed using validated tools adapted to each study design. Meta-analyses of correlations were performed using an inverse variance restricted maximum likelihood random-effects.

Results

The initial search yielded 2463 references and seventy-one studies were finally included. We found a weak-to-moderate inverse association between patient empowerment-related constructs and both anxiety (r = -0.22) and depression (r = -0.29). Moreover, empowerment-related constructs were moderately negatively correlated with distress (r = -0.31) and moderately positively correlated with general quality of life (r = 0.32). Small associations between empowerment-related constructs and both mental (r = 0.23) and physical quality of life (r = 0.13) were also reported.

Discussion

This evidence is mostly from cross-sectional studies. High-quality prospective studies are needed not only to better understand the role of patient empowerment but to assess causal associations. The results of the study highlight the importance of patient empowerment and other empowerment-related constructs such as self-efficacy or perceived control in diabetes care. Thus, they should be considered in the design, development and implementation of effective interventions and policies aimed at improving psychosocial outcomes in patients with type 2 diabetes.

Chronic Conditions and Psychological Distress in Older Asian Americans: The Mediating Role of Subjective Health Perception

Given the importance of understanding the connection between physical and mental health in old age, the study examined the mediating role of subjective health perception in the relationship between chronic conditions and psychological distress among older Asian Americans. Using data from 533 Asian Americans aged 60 and over in the 2016 Asian American Quality of Life Study, the direct and indirect effect models were tested with multivariate linear regressions and the PROCESS macro. Results show that chronic conditions pose significant risks to psychological distress and that subjective health perception mediates their association. The observed role of subjective health perception as an intervening step between physical and mental health offers implications for gerontological social work research and practice by highlighting the importance of positive self-appraisals for the health and well-being in later years of life.

Relationship between illness perception, fear of progression and quality of life in interstitial lung disease patients: A cross-sectional study

AIMS AND OBJECTIVES

This study aimed to investigate whether fear of progression mediates the association between illness perception and quality of life among interstitial lung disease patients.

BACKGROUND

So far, the physiological treatment of interstitial lung disease is limited. In addition to immunosuppressants such as glucocorticoids, two anti-fibrosis drugs (pirfenidone and nintedanib) have shown moderately beneficial effects on slowing the progression of interstitial lung disease fibrosis. However, none of these drugs has shown reliable or strong beneficial effects on improving quality of life. Psychological care and mental health support strategies focusing on improving patients' quality of life are particularly important.

DESIGN

A cross-sectional study.

METHODS

A convenience sample of patients suffering from interstitial lung disease were enrolled from August to December 2019. Data including sociodemographic and clinical characteristics, illness perception, fear of progression and quality of life were collected. The descriptive analysis and Pearson correlations were analysed by SPSS 26.0 (IBM Corp.). PROCESS v3.4 (by Andrew F. Hayes) macro was applied to analyse the mediating effects. We used the STROBE checklist to report the results.

RESULTS

Both illness perception and fear of progression were correlated with quality of life. Fear of progression mediated the association between illness perception and quality of life. The indirect effect was 0.121, and the proportion of intermediary effect in the main effect was 26.36%.

CONCLUSION

Interstitial lung disease patients experience relatively poor quality of life and fear of progression exerts a mediating role between illness perception and quality of life.

RELEVANCE TO CLINICAL PRACTICE

This study alerts medical staff to pay attention to negative illness perception and excessive fear, which is helpful to formulate effective interventions to manage interstitial lung disease patients' quality of life.
