We examined the relationship between socioeconomic status (SES) and endorsement of honour. We studied the SES-honour link in 5 studies (N = 13,635) with participants recruited in different world regions (the Mediterranean and MENA, East Asian, South-East Asian, and Anglo-Western regions) using measures that tap into various different facets of honour. Findings from these studies revealed that individuals who subjectively perceived themselves as belonging to a higher (vs.

Objectives: The EQ Health and Wellbeing (EQ-HWB) is a new generic measure that captures constructs beyond health-related quality of life, with a 25-item long form and a shorter 9-item version (EQ-HWB-S). This study aimed to assess the psychometric performance of both versions in breast cancer, which is the most prevalent cancer worldwide, and compare them with other instruments.

Methods: A longitudinal survey in Indonesia (2023-2024) with 300 female patients used the EQ-HWB, 5-level EQ-5D (EQ-5D-5L), Functional Assessment of Cancer Therapy - General (from which Functional Assessment of Cancer Therapy Eight Dimension [FACT-8D] was derived), and Warwick-Edinburgh Mental Wellbeing Scale (WEMWBS, from which the Short WEMWBS was derived).

Background: Financial toxicity describes the impairment of financial wellbeing in patients due to the burden of cancer diagnosis and care. The COST: A Functional Assessment of Chronic Illness Therapy Measure of Financial Toxicity (FACIT-COST) is the most widely used cancer-specific measure of subjective financial toxicity, having been validated in multiple languages, but not in Indonesian. This study aimed to validate the Indonesian version of FACIT-COST in a breast cancer sample.

In the past decade, the concept of dyadic coping as a buffer against stress in romantic relationships has received much attention in Western countries, but it has rarely been studied in non-Western countries and among parents with school-aged children. The aim of the present study was to investigate the moderating effect of dyadic coping on the link between financial strain and marital satisfaction, as well as the mediating effect of marital satisfaction on the relationship between financial strain and quality of life. There were 751 heterosexual couples whose eldest child aged 7-12 years in West Java, Indonesia (mean age husband = 37.

Unlabelled: PURPOSE  : To assess gender differences in COVID-19 related changes in home and work responsibilities longitudinally, and determine whether these differences, together with other potential risk and protective factors, are associated with depression, anxiety, and post-traumatic stress disorder (PTSD) symptomatology.

Method: Symptoms of depression, anxiety, and PTSD were measured using an online survey instrument, between May 2020 and April 2021, in four waves completed at 3-monthly intervals. Analyses were based on data from the COvid MEntal healTh (COMET) survey which investigated the mental health effects of the COVID-19 outbreak spanning 13 countries on five continents in N = 7,909 participants.

Introduction: Emotion dysregulation is a transdiagnostic marker for vulnerability and has high comorbidity rates across various range of disorders among adolescents and young adults, highlighting the crucial need for precise assessment tools to recognize its significant impact on well-being. The Difficulties in Emotion Regulation Scale Short Form (DERS-SF) is a comprehensive instrument designed to measure the ability to regulate emotion. This study aimed to investigate the psychometric properties of DERS-SF among the non-clinical population, particularly high school and university students in Indonesia.

The Indonesian government implemented a large-scale social restriction policy as part of the efforts to tackle the COVID-19 pandemic. This policy impacted the population, including mothers, and caused considerable psychological distress. Individual efforts to cope (avoidant and approach coping strategies) and support from significant persons might help handle the distress experienced by mothers.

Background: The EuroQol Group recently developed two new instruments, the EQ Health and Wellbeing (EQ-HWB) and the EQ Health and Wellbeing short version (EQ-HWB-S). The EQ-HWB and EQ-HWB-S are intended to capture a broad range of health and broader quality of life aspects, which may be relevant to general public members, patients, their families, social care users and informal carers. This study assesses the content validity of the Italian version of the two instruments in a sample of Italian patients, social care users and informal carers.

Objectives: To estimate a Saudi-specific value set for the EQ-5D-5L questionnaire using the EuroQol Valuation Technology program and the EuroQol Group's standard protocol.

Methods: Participants were quota-sampled from the Saudi adult population based on residency location, age group, gender, education level, and employment status. The participants were guided through the completion of composite time trade-off (cTTO) and discrete choice experiment (DCE) tasks by trained interviewers using EuroQol Valuation Technology software.

Objectives: A growing interest in healthcare costs and patients' health-related quality of life (HRQoL) exists in the context of the increasing importance of health technology assessment in countries with high numbers of the HIV and tuberculosis (TB) patient populations, such as Indonesia. This study aimed to analyze the HRQoL and out-of-pocket (OOP) costs of HIV, TB, and TB/HIV coinfected participants in a city in Indonesia with a high prevalence of HIV and TB.

Methods: A cross-sectional survey was conducted in the voluntary counseling and testing and lung clinics of Bekasi City Public Hospital (Indonesia) from January to March 2018.

One of the important outcomes to define the success of cancer treatment is the health-related quality of life (HRQoL) that can be measured using generic and/or specific instruments. Our study aims to define the cancer patients' HRQoL in some hospitals in Indonesia as measured by the European Organization for Research and Treatment for Cancer (EORTC QLQ-C30) and the EQ-5D-5L, to define the differences of cancer patients' HRQoL referring to patients' characteristics, and to explore determinants of cancer patients' HRQoL. We recruited 451 cancer patients using a cross-sectional design in two referral hospitals in Central Java, Indonesia, using the purposive sampling technique.

Background And Objectives: Methods for estimating health values in adult populations are well developed, but lag behind in children. The EuroQol standard protocol to arrive at value sets for the youth version of the EQ-5D-Y-3L combines discrete choice experiments with ten composite time trade-off values. Whether ten composite time trade-off values are sufficient remains to be seen and this is one of the reasons the protocol allows for experimental expansion.
