Association of perceived inequality, relative deprivation and loneliness with the trajectory of anger in university students.

Objective: To examine the trajectory of anger and its psychosocial predictors (i.e., perceived social inequality, relative deprivation, and loneliness) as well as its association with anxiety and depression.

Do posttraumatic stress symptoms predict trajectories of sleep disturbance and fatigue in patients with breast cancer? A parallel-process latent growth model.

Objective: Using a parallel-process latent growth model (LGM), this study examined whether posttraumatic stress symptoms (PTSS) are associated with the trajectory of sleep disturbance (SD) and fatigue and whether the SD trajectory mediates the PTSS-fatigue relationship.

Methods: Data were from 215 patients with breast cancer recruited from a tertiary hospital in South Korea. A self-report survey was administered at four time points during the course of adjuvant chemotherapy.

Trajectory of fear of cancer recurrence and beliefs and rates of medication adherence in patients with breast cancer.

Objective: This study examined the growth trajectory of fear of cancer recurrence (FCR) and its predictors, and the association of that trajectory with the beliefs and rates of medication adherence in patients with breast cancer.

Methods: Two hundred and ten patients with breast cancer undergoing adjuvant endocrine therapy in a university hospital in Seoul, Korea, were followed up five times over 18 months following surgery, and data from the final 162 patients were analyzed.

Results: Latent class growth analysis identified three classes.

A network analysis of the Brief Illness Perception Questionnaire in patients with rheumatic diseases and human immunodeficiency virus infection.

To examine the construct of illness perception (IP) as measured by the Brief Illness Perception Questionnaire (BIPQ) using network analysis in patients with rheumatic diseases (RD) and with human immunodeficiency virus infection and acquired immune deficiency syndrome (HIV/AIDS). Cross-sectional and multicentre survey. The BIPQ and the Hospital Anxiety and Depression Scale.

Profiles of depressive symptoms and the association with anxiety and quality of life in breast cancer survivors: a latent profile analysis.

Purpose: The aim of this study was to examine profiles of depressive symptoms and the association with anxiety and quality of life (QOL) in breast cancer survivors.

Methods: A cross-sectional multicenter survey involving 5 hospitals in Korea was implemented between February 2015 and January 2017. A self-report survey included the Patient Health Questionnaire-9, Short Form 36, and State and Trait Anxiety Scale.

Cross-Cultural Validation of the Korean Version of the Chalder Fatigue Scale.

Purpose: University students are vulnerable to fatigue. If not adequately dealt with, fatigue might develop into various health problems and negatively affect quality of life (QOL). The present study examined psychometric properties of the Korean version of the Chalder Fatigue Scale (K-CFQ) in university students.
