Existing studies that assess the impact of cooking with dirty solid fuels on human beings tend to underestimate the adverse impact on welfare. This paper aims to address this research gap by examining the happiness benefits of transitioning from solid fuel to cleaner alternatives. Using an extensive panel dataset from China, which includes 150,248 observations collected from 43,251 survey respondents interviewed between 2010 and 2018, this study employs various complementary methodologies, such as the fixed-effect model, propensity score matching, and time-varying difference-in-differences, to overcome challenges related to treatment selection bias and unobserved time-invariant heterogeneity. Further, life satisfaction approach is used to evaluate the economic benefits of cooking energy transition. Our findings indicate that switching from firewood to LPG/natural gas/gas can significantly enhance individual subjective well-being (SWB). Although the improvement brought about by electricity is slightly lower than that of LPG/natural gas/gas, it remains substantial. Notably, the positive effect is more pronounced among specific demographic groups, including females, rural residents, and low-income families. Moreover, these well-being improvements can manifest quickly and persist many years before any noticeable enhancements in physical health. This effect further amplifies over time. However, biogas shows no significant effect on SWB. These findings underscore the importance of clean fuels that contribute to increased happiness, as they are more likely to be consistently adopted. Finally, we estimate that the economic benefits of the well-being improvements resulting from the use of LPG/natural gas/gas and electricity range between $5.15 and $5.44 per day.

UNASSIGNED: This study aims to investigate whether exercise adherence and positive mental character significantly affect subjective well-being among Chinese college students during the COVID-19 pandemic and whether positive mental character plays a mediating role.
UNASSIGNED: The study employed questionnaires, including the Exercise Adherence Scale, the Positive Mental Character Scale, and the Subjective Well-Being Scale, which were administered to students across seven universities in Henan Province, China. A total of 1,001 participants were analyzed in the final sample. Data were analyzed using SPSS 21.0 for descriptive statistics, independent samples T-test, correlation, and regression analyses. Furthermore, structural equation model with AMOS was conducted to examine the potential mediating effect of positive mental characteristics on the relationship between exercise adherence and subjective well-being.
UNASSIGNED: The results indicated significant differences in exercise adherence, positive mental character, and subjective well-being between male and female participants, with males scoring higher in all three domains. Among Chinese university students during the COVID-19 pandemic, there was a significant correlation among exercise adherence, positive mental character, and subjective well-being. Exercise adherence was found to have a significant and positive impact on both positive mental character and subjective well-being. Additionally, it was found that positive mental character had a significant positive association with subjective well-being. The mediating role of positive mental character in the relationship between exercise adherence and subjective well-being was partially supported.
UNASSIGNED: Exercise adherence among Chinese college students had a significant positive association on both positive mental character and subjective well-being throughout the COVID-19 pandemic. The exercise adherence can directly or indirectly enhance subjective well-being through its association with positive mental character. Therefore, positive mental and subjective well-being can be enhanced by consistent physical activity even during a pandemic.

BACKGROUND: Subjective wellbeing (SWB) and health are important facets of any person\'s life, and they tend to influence each other. This importance is reflected in the vastness of literature aiming to explore this association. However, most of this literature is based on sampling national population which may present different population characteristics to those of a province. Thus, the paper aims to investigate if the association between perceived health and SWB is moderated by population characteristics at a provincial level. We intend to add value to subjective wellbeing and health literature by reviewing the relationship between SWB and health in the Eastern Cape stratified by age, gender, rural and urban and different income classifications.
METHODS: Different population characteristics tend to associate to subjective wellbeing and health differently, therefore influencing how these two variables influence each other. Thus, the paper aims to investigate if the association between perceived health and SWB is moderated by population characteristics at a provincial level. Utilising the South African National Income Dynamics Survey from 2008 to 2017, this study examined the relationship between subjective wellbeing and health using a random effects model stratified according to aforementioned population characteristics.
RESULTS: A better perceived health status is associated with higher subjective wellbeing. A better subjective wellbeing is also associated with a higher health status. Determinants of subjective wellbeing and health associate with these variables differently besides income and employment which led to higher subjective wellbeing and health. Health associates to subjective wellbeing different across populations characteristics.
CONCLUSIONS: Subjective wellbeing and health are interdependent as reflected in the World Health Organisation (WHO) and United Nation (UN) statements. Higher income and level of education and being employed is associated with both higher SWB and health. Therefore, improving these economic outcomes maybe associated with an improvement in well-being and health as desired by WHO and UN. Provinces differ, and different population characteristics tend to associate with subjective wellbeing and health differently, therefore influencing how these two variables influence each other. Health improvement policies must consider subjective wellbeing. Well-being improvement policies need to be cognisant of the differences in provincial and population characteristics.

OBJECTIVE: Hopelessness is a risk factor for suicidal ideation, whereas subjective well-being and resilience are protective factors. Nevertheless, the complicated mechanism underlying these factors has not been fully investigated among older people with moderate to severe ADL limitations in nursing homes. This cross-sectional study investigated the potential role of resilience in mediating the relationship between hopelessness and suicidal ideation as well as whether subjective well-being can moderate this mediating effect.
METHODS: Older individuals (N = 332; aged ≥ 65 years; 158 males, 174 females) with moderate to severe ADL limitations from 10 nursing homes in Chongqing, China, completed this cross-sectional study from July to December 2022. Hopelessness, resilience, subjective well-being and suicidal ideation were measured. The mediating and moderating effects were explored via regression analysis with bootstrap methods.
RESULTS: A total of 32.8 % (109/332) of the participants reported current suicidal ideation. The relationship between suicidal ideation and hopelessness was partly influenced by resilience (indirect effect = 0.13, 95 % CI = 0.07∼.20). Subjective well-being moderated the impact of resilience on suicidal ideation (moderating effect = 0.01, 95 % CI = 0.00∼.01) and indirectly impacted the effect of hopelessness on suicidal ideation.
CONCLUSIONS: These results emphasize the importance of resilience and subjective well-being in mitigating suicidal ideation, which is a prevalent issue among older adults residing in nursing homes with moderate to severe ADL limitations in China.

UNASSIGNED: Disturbed sleep during infancy and early childhood can have a detrimental effect on parental sleep and consequently parental well-being. However, there is a paucity of research on how perceived child sleep problems and behavioural sleep interventions as treatment influence maternal subjective well-being.
UNASSIGNED: This study aimed to explore the incidence of subjective well-being in mothers of children with sleep problems and whether implementing two behavioural sleep interventions changed their well-being.
UNASSIGNED: The research was conducted in a community setting, with parents voluntarily approaching a sleep consultancy based in South Africa.
UNASSIGNED: Using data from 119 mothers voluntarily approaching a sleep consultancy in South Africa, a pre-test-post-test design was employed to investigate changes in life satisfaction, affect, couple satisfaction, perceived stress and depression approximately 3 weeks after implementation of a sleep intervention.
UNASSIGNED: Results indicate that mothers of children with sleep problems experienced moderate to high life satisfaction and positive affect although the presence of moderate negative affect, couple satisfaction and stress and mild depression suggest possible decreased subjective well-being.
UNASSIGNED: Findings suggest implementation of graduated extinction and extinction with parental presence sleep interventions may improve life satisfaction, affect, stress and depression but not couple satisfaction in the short-term.
UNASSIGNED: This study contributes towards understanding the effect of sleep loss on the subjective well-being of mothers and provides preliminary evidence regarding the benefits of two sleep interventions for improving maternal subjective well-being.

BACKGROUND: The burgeoning field of research on the dual-factor model of mental health (DFM) has highlighted its significance, yet the applicability of the DFM in military personnel and its longitudinal relationships with different dimensions of meaning in life remains unclear. This study aimed to clarify the applicability of the DFM for military personnel and to investigate longitudinal relationships between the dual factors of mental health (negative factor, positive factor) and the two dimensions of meaning in life (presence of meaning, search for meaning) in military personnel.
METHODS: In this study, data were collected in two waves (April and August 2023) from 227 Chinese military personnel. We constructed a dual-factor model with depression as the negative factor and subjective well-being as the positive factor, and we compared it with a single-factor model to determine if DFM could be applied to military personnel. We also constructed a cross-lagged model to investigate longitudinal relationships between depression, subjective well-being, presence of meaning, and search for meaning.
RESULTS: According to the findings, military personnel fit better with the DFM than with the single-factor model. Cross-lagged analysis results revealed that both the presence of meaning and the search for meaning negatively predicted depression and positively predicted subjective well-being.
CONCLUSIONS: The DFM had good applicability among military personnel. Both the presence of meaning and the search for meaning could improve military mental health, suggesting that both dimensions of meaning in life may be potential targets for improving military mental health.

UNASSIGNED: To assess the association between erectile dysfunction and subjective well-being among primary care patients with type 2 diabetes mellitus.
UNASSIGNED: This cross-sectional study included 340 men with type 2 diabetes treated in primary health care settings in the Ismailia governorate between April 2021 and April 2022. A multistage random cluster sampling technique was used. Sociodemographic data, disease characteristics, lifestyle, surgical and sexual history, and the Arabic translations of the abridged 5-item version of the International Index of Erectile Function (IIEF-5) Questionnaire, and the 5-item World Health Organization Well-Being Index (WHO-5) were gathered.
UNASSIGNED: Erectile dysfunction was identified in 72.94% of diabetic patients, with 55% mild or mild-to-moderate (ED I), and 17.9% moderate or severe (ED II). Twenty percent had Poor subjective well-being, with a mean WHO-5 index of 63.4 (± 15.4). Binary logistic regression analysis showed that education, diabetes duration, insufficient income, dyslipidemia, benign prostate hyperplasia, and IIEF-5 score were significantly associated with poor subjective well-being. Increasing IIEF-5 score was significantly associated with a 22% decrease in the odds of poor subjective well-being (OR: 0.78; 95% CI 0.66-0.93). Multinomial regression analysis showed that increasing score of the WHO-5 well-being index was associated with a 11% and 14% reduction in the odds of ED I and II, respectively (OR: 0.89 (95% CI 0.86-0.93), and 0.86 (95% CI 0.81-0.92), respectively).
UNASSIGNED: Erectile dysfunction and subjective well-being were interrelated. Early detection of erectile dysfunction is essential for improving the positive mental health of men with type 2 diabetes in primary care.

UNASSIGNED: The Internet is a popular source of health information, but too much research can cause anxiety (cyberchondria). Medical and non-medical personnel interpret information differently, leading to varying rates of cyberchondria. Smartphone addiction may also contribute to cyberchondria and impact mental health.
UNASSIGNED: The study was an epidemiological survey-based investigation with a cross-sectional design involving undergraduate students (aged 18 years or older) from Indian universities or colleges. The study utilized the Cyberchondria Severity Scale-Short Form (CSS-12), WHO-5 well-being index, and Smartphone Addiction Scale-Short Version (SAS-SV).
UNASSIGNED: A total of 1033 participants (53.1% females and 46.4% males) were recruited in the survey. Of the participants, 58.5% were pursuing medical or paramedical courses, while the remaining 41.5% belonged to the non-medical group. High-severity cyberchondria was present in about 4.4% of the students. The medical cohort demonstrated a significantly lower cumulative CSS in comparison to the non-medical cohort (t = - 3.90; P < 0.01). Smartphone addiction was observed in 57.2% of individuals in the medical group and 55.9% of individuals in the non-medical group (P = 0.68). Medical students had a significantly lower mean well-being score compared to non-medical students (58.4 vs. 59.6; P < 0.01). There was a positive correlation between cyberchondria severity and smartphone addiction, which was consistent across both groups.
UNASSIGNED: Medical students have less cyberchondria than non-medical students. Cyberchondria severity is linked to smartphone addiction. Non-medical students with cyberchondria have higher subjective well-being.

Positive Illusion, as an important mechanism of cognitive adaptation in positive psychology, enhances positive information feedback, thereby boosting self-worth. This study involved 803 college students from Shaanxi Province, China, surveyed between March 1 and August 31, 2023. The Positive Illusion, Psychological Resilience, and Subjective Well-Being scales were utilized to examine the characteristics and interrelationships of these constructs through path analysis. The findings indicated that college students\' levels of Positive Illusions were generally moderate to low (t = 75.04, p < .001), Psychological Resilience levels were low (t = 129.96, p < .001), and their Subjective Well-Being was generally good (t = 222.33, p < .001). Significant positive correlations were found between Subjective Well-Being and Psychological Resilience (r = 0.48, p < .01); Positive Illusions and Psychological Resilience (r = 0.59, p < .01); and Subjective Well-Being and Positive Illusions (r = 0.49, p < .01). Idealization, Controllability, and Optimism in Positive Illusions partially mediated the relationship between Psychological Resilience and Subjective Well-Being, with mediation effect proportions of 16.13%, 12.43%, and 12.69% respectively. Pathways for enhancing college students\' Subjective Well-Being are explored, offering relevant theoretical and practical guidance for mental health.

Research consistently demonstrates a positive association between dispositional optimism (DO) and subjective well-being (SWB). This study takes a step forward by exploring potential mechanisms underlying this relationship, with a specific focus on the mediating role of mindful self-care (MSC). We conducted a cross-sectional online survey involving 312 Singaporean adults. Participants completed questionnaires assessing their DO, MSC practices, and overall SWB. Our findings confirmed a significant link between DO and SWB, with individuals exhibiting higher optimism reporting greater well-being. Importantly, the relationship was mediated by MSC, suggesting that optimism motivates individuals to engage in MSC practices, which in turn, enhances SWB. Moreover, DO was linked to all SWB subcomponents, even after controlling for MSC as a mediator. Among the six MSC facets, self-compassion and purpose, supportive relationships, and mindful awareness emerged as significant mediators. This study adds to the growing body of evidence recognizing the positive role of DO and MSC in improving well-being outcomes. It highlights the potential of interventions aimed at cultivating optimism as a promising approach for enhancing mindful self-care practices and ultimately promoting well-being in adults.
