The dyadic effects of personality traits on depression in advanced lung cancer patients and caregivers: The mediating role of acceptance of illness

Mapping the terrain: a scoping review of empirical studies on the big five personality traits and QoL in China

The relationship between personality traits and Quality of Life (QoL) has garnered increasing scholarly attention, particularly within the context of China. This scoping review synthesizes existing literature on the connection between the Big Five personality traits (Openness, Conscientiousness, Extraversion, Agreeableness, and Neuroticism) and QoL among the Chinese population. The review explores correlations, measurement instruments, and theoretical frameworks employed in these studies. The study's significance lies in the profound implications for healthcare policies, organizational behavior, and social welfare programs in China, where rapid social and economic changes impact well-being. Investigating personality traits' impact on QoL can inform tailored interventions benefiting diverse Chinese subpopulations. This review addresses three primary research questions: (1) How do the Big Five personality traits correlate with QoL in different Chinese subpopulations, and what are the mediating or moderating factors? (2) What instruments assess these traits and QoL in the Chinese cultural context, and how are they validated? (3) What theoretical or disciplinary frameworks guide this research in China? Following a systematic PRISMA-ScR framework and a customized "C-BFQLC" protocol, the study identified 170 relevant documents. After rigorous screening, ten studies met the inclusion criteria, constituting 5.03% of the initial records. This scoping review critically examines the interplay between the Big Five personality traits and QoL in China, a context marked by rapid socioeconomic changes and cultural diversity. Employing a systematic approach guided by the PRISMA-ScR framework and our unique 'C-BFQLC' protocol, we meticulously analyzed 170 documents, selecting nine that met our rigorous inclusion criteria. Despite the emerging nature of this research area in the Chinese context, our study reveals significant insights into how individual personality traits influence various dimensions of well-being. The implications of these findings are profound, extending beyond academic discourse to inform healthcare policies, organizational behavior, and social welfare programs in China. Our review not only offers a comprehensive synthesis of the current research landscape but also identifies critical gaps in the literature. It emphasizes the urgent need for further culturally nuanced research to understand the complex dynamics of personality traits and QoL in China. This work lays a foundational framework for future investigations and the development of tailored interventions aimed at enhancing the well-being of diverse Chinese populations, including the elderly, people with disabilities, and specific occupational groups.

Dyadic effects of family resilience on quality of life in patients with lung cancer and spousal caregivers: The mediating role of dyadic coping

PURPOSE

This study explored the effects of family resilience on quality of life (QOL) and examined whether dyadic coping mediates these effects in patients with lung cancer and their spousal caregivers.

METHODS

In total, 313 dyads were recruited from three tertiary hospitals in Fujian Province, China, between March and July 2022. Study participants independently completed sociodemographic and clinical characteristics questionnaires, the Shortened Chinese version of the Family Resilience Assessment Scale, the Dyadic Coping Inventory, and the 8-Item Short-Form Health Survey. Data analysis utilized the actor-partner interdependence mediation model (APIMeM).

RESULTS

Family resilience of both patients with lung cancer and their spouses were positively and directly associated with their own QOL, which was mediated by dyadic coping. Family resilience did not significantly influence the partners' QOL. The APIMeM model produced acceptable fit (χ2/df = 2.857, RMSEA = 0.077, CFI = 0.992, TLI = 0.941, and NFI = 0.998).

CONCLUSION

Dyadic coping mediated both actor and partner effects between family resilience and QOL, and there was no significant direct partner effect between individual family resilience and their partner's QOL. The development of efficient family- or dyad-based interventions is essential to improve family resilience and encourage dyadic coping strategies among patients with lung cancer and their spousal caregivers who experience poor family resilience and low dyadic coping. Such interventions have the potential to enhance QOL for both parties.

Neuroticism as a moderator of symptom-related distress and depression in 4 noncancer end-of-life populations

OBJECTIVES

Neuroticism is a significant predictor of adverse psychological outcomes in patients with cancer. Less is known about how this relationship manifests in those with noncancer illness at the end-of-life (EOL). The objective of this study was to examine the impact of neuroticism as a moderator of physical symptoms and development of depression in patients with amyotrophic lateral sclerosis (ALS), chronic obstructive pulmonary disease (COPD), end-stage renal disease (ESRD), and frailty in the last 6 months of life.

METHODS

We met this objective using secondary data collected in the Dignity and Distress across End-of-Life Populations study. The data included N = 404 patients with ALS (N = 101), COPD (N = 100), ESRD (N = 101), and frailty (N = 102) in the estimated last 6 months of life, with a range of illness-related symptoms, assessed longitudinally at 2 time points. We examined neuroticism as a moderator of illness-related symptoms at Time 1 (∼6 months before death) and depression at Time 2 (∼3 months before death) using ordinary least squares regression.

RESULTS

Results revealed that neuroticism significantly moderated the relationship between the following symptoms and depression measured 3 months later: drowsiness, fatigue, shortness of breath, wellbeing (ALS); drowsiness, trouble sleeping, will to live, activity (COPD); constipation (ESRD); and weakness and will to live (frailty).

SIGNIFICANCE OF RESULTS

These findings suggest that neuroticism represents a vulnerability factor that either attenuates or amplifies the relationship of specific illness and depressive symptoms in these noncancer illness groups at the EOL. Identifying those high in neuroticism may provide insight into patient populations that require special care at the EOL.

Changes in maternal and paternal body composition during the transition to parenthood (TRANSPARENTS)

OBJECTIVE

The transition to parenthood might negatively influence health-related behavior and can result in increased adiposity. The aim of this study was to investigate how body composition in mother-father dyads changes from pregnancy up to 6 months post partum.

METHODS

Anthropometrics were collected from 144 nulliparous couples at 12 weeks of gestation (PG12) and 6 weeks (PP6WK) and 6 months (PP6M) post partum. A longitudinal dyadic confirmatory factor analysis model was used to analyze changes in body composition. Body composition was treated as a latent variable using BMI, body fat percentage, and waist circumference as indicators.

RESULTS

For women, latent means increased at 6 weeks post partum (PP6WK - PG12: +1.115, SE: 0.117, p < 0.001), decreased again at 6 months post partum (PP6M - PP6WK: -0.368, SE: 0.107, p < 0.001), but remained above baseline levels (PP6M - PG12: +0.747; SE: 0.115, p < 0.001). For men, the latent means at follow-up were higher than at baseline (PP6WK-PG12: +0.370, SE: 0.075; PP6M-PG12: +0.366, SE: 0.084, both p < 0.001).

CONCLUSIONS

Increases in latent means correspond to unfavorable changes in BMI, body fat percentage, and waist circumference. These changes were observed from the beginning of pregnancy up to 6 months post partum. Weight management for both women and men during pregnancy and the early postpartum period is recommended and fathers should be included in pre- and postnatal standard care.

Caregiver activation of relatives of patients with advanced cancer

OBJECTIVE

Relatives of patients with advanced cancer often have many caring responsibilities. Not everyone may have sufficient knowledge, skills, and confidence-also known as caregiver activation-to provide such care. We assessed caregiver activation in relatives and its association with their personal characteristics and their own well-being.

METHODS

A cross-sectional study among relatives of patients with advanced cancer. Measures included caregiver activation (C-PAM), resilience, personal self-care, caregiver burden, depressive symptoms, quality of life, and social well-being. The C-PAM distinguishes four levels of activation, ranging from poor (level 1) to adequate (level 4). Bivariate and multivariable regression analyses were performed.

RESULTS

Two hundred fifty-four relatives were included; 32% had level 1 activation, 30% level 2, 27% level 3 and 11% level 4. Higher levels of caregiver activation were found among partners, those who provided more hours of informal care, were more resilient, and scored higher on personal self-care. Higher caregiver activation was associated with lower caregiver burden, less depressive symptoms, and better social well-being.

CONCLUSION

In our study, the majority of relatives seem insufficiently prepared to provide care for their loved one. Supporting them in gaining knowledge, skills, and confidence to provide such care may improve their own well-being.
