Happiness and its relation to psychological well-being of adolescents

Happy people are always similar: The evidence from brain morphological and functional inter-subject correlations

A fundamental question in the study of happiness is whether there is neural evidence to support a well-known hypothesis that happy people are always similar while unfortunate people have their own misfortunes. To investigate this, we employed several happiness-related questionnaires to identify potential components of happiness, and further investigated and confirmed their associations with personality, mood, aggressive behaviors, and amygdala reactivity to fearful faces within a substantial sample size of college students (n = 570). Additionally, we examined the functional and morphological similarities and differences among happy individuals using the inter-subject representational similarity analysis (IS-RSA). IS-RSA emphasizes the geometric properties in a high-dimensional space constructed by brain or behavioral patterns and focuses on individual subjects. Our behavioral findings unveiled two factors of happiness: individual and social, both of which mediated the effect of personality traits on individual aggression. Subsequently, mood mediated the impact of happiness on aggressive behaviors across two subgroup splits. Functional imaging data revealed that individuals with higher levels of happiness exhibited reduced amygdala reactivity to fearful faces, as evidenced by a conventional face-matching task (n = 104). Moreover, IS-RSA demonstrated that these participants manifested similar neural activation patterns when processing fearful faces within the visual pathway, but not within the emotional network (e.g., amygdala). Morphological observations (n = 425) indicated that individuals with similar high happiness levels exhibited comparable gray matter volume patterns within several networks, including the default mode network, fronto-parietal network, visual network, and attention network. Collectively, these findings offer early neural evidence supporting the proposition that happy individuals may share common neural characteristics.

Adolescents' stress and depressive symptoms and their associations with psychological flexibility before educational transition

INTRODUCTION

Relatively little is known about individual differences in adolescent psychological flexibility and its associations with symptoms of stress and depression. This study examined different profiles of adolescent stress and depressive symptoms and their associations with developing psychological flexibility before the critical educational transition.

METHODS

The data were derived from a general sample of 740 Finnish ninth-grade adolescents (Mage  = 15.7 years, 57% female) who were assessed twice during the final grade of their basic education. The data were analyzed using growth mixture modeling.

RESULTS

Four profiles of stress and depressive symptoms were identified during a school year: (1) no stress and no depressive symptoms (None; 69%); (2) mild and decreasing stress and depressive symptoms (Decreasing; 15%); (3) low but increasing stress and depressive symptoms (Increasing; 6%); and (4) high and stable levels of stress and depressive symptoms (High; 10%). The adolescents in these profiles differed from each other in their initial levels and changes of psychological flexibility. The initial level of psychological flexibility was highest in the no-symptom profile group. We observed simultaneous change trends in symptoms and psychological flexibility during a school year. When symptoms decreased, psychological flexibility increased, and when symptoms increased, psychological flexibility decreased.

CONCLUSIONS

A bidirectional pattern of relationships between psychological flexibility and psychological symptoms was found. Despite initially high level of skills in psychological flexibility, some adolescents, unexpectedly, experienced increased symptoms of stress and depression during the school year. The results call for further studies to explore in-depth the developmental diversity in adolescents' well-being and its antecedents.

The Impact of Optimism and Internal Locus of Control on Workers’ Well-Being, A Multi-Group Model Analysis before and during the COVID-19 Pandemic

The COVID-19 crisis led to changes in different areas of workers’ lives, as well as repercussions in stress management, social relationships, and perception of personal and professional growth. Considering this, well-being in the workplace is crucial to carrying out effective activities and performance, and it is also essential to verifying the impact of the pandemic on the current situation of workers’ overall well-being. The study investigates the mediation of Personal Growth (PG) between two personal resources at work, Internal Locus (LOCI) and Optimism (OPT), on the Pemberton Happiness Index (PHI), an important multi-faceted indicator of well-being. This study was conducted on respondents performing professions (n = 666), both before (2019, n = 410) and during the pandemic (2020, n = 256). The relationships were tested simultaneously using a multi-group structural equation model (MPLUS7). The estimated model shows that personal resources at work increase PG (LOCI mostly during the pandemic; OPT mostly before the pandemic); OPT directly increases PHI; PG increases PHI (mostly before the pandemic); and personal resources increase through PG and PHI (LOCI more during the pandemic; OPT more before the pandemic). The study is cross-sectional, as it was not possible to compare the same workers over two years. The research offers ideas for activation of training programs, support and development of individual resources, and personal growth aimed at improving well-being and the work experience for workers.

The Relationship between Children's School Adaptation, Academic Achievement, Happiness, and Problematic Smartphone Usage: A Multiple Informant Moderated Mediating Model

The school environment is a primary realm of life for school-aged children and thus their adaptation to school and academic performance may affect their degree of happiness. The age of smartphone users has declined, and problematic smartphone usage has widely expanded such that young children are also affected by such devices. This study assessed adaptation to school, academic achievement, problematic smartphone usage, and general happiness in a panel data sample of 695 Korean 10-year-old children and their teachers and mothers, and a moderated mediation model of these variables was tested. Results revealed that school adaptation affected general happiness of children through academic performance, and problematic smartphone usage demonstrated significant moderating effects on the relationship between school adaptation and academic achievement. Specifically, in children with a high level of adaptation to school life, the difference in problematic smartphone usage did not affect academic performance. However, lower level of adaptation led to greater differences in academic performance depending on problematic smartphone usage, and children with high problematic smartphone usage showed poorer academic performance. This study is meaningful because variables related to adaptation of 10-year-old children were collected from multiple informants. In addition, this study focused on general happiness, a positive factor, as the outcome variable to test the effects of variables related to school and problematic smartphone usage. Limitations include that a causal relationship cannot be examined, and qualitative differences in smartphone usage were not measured.

Happiness and Achievement Motivation among Iranian Nursing Students: A Descriptive Correlational Study

Background

Happiness and achievement motivation are two important concepts in students' lives. Therefore, this study was aimed at investigating the association between happiness and achievement motivation in undergraduate nursing students and examining their relationship with students' demographic characteristics.

Method

A descriptive correlational study was undertaken; 255 undergraduate nursing students enrolled in one nursing school in an urban area of Iran during the academic year 2017-2018 were included in the study using census method sampling. The demographic data questionnaire, Oxford Happiness Questionnaire (OHQ), and Hermans Achievement Motivation Questionnaire (HAMQ) were used for data collection. Data were analyzed using univariate analysis and multivariate linear regression analysis.

Results

The total mean (SD) of happiness and achievement motivation scores were 40.73 (11.20) and 82.61 (7.50), respectively. There was a direct significant correlation between happiness and achievement motivation (r = 0.36, p < 0.001). An inverse significant association between happiness and students 21-24 years old (β = −3.99, p < 0.03) was found. There was a direct significant association between happiness and being married (β = 5.33, p = 0.03) and interest in nursing (β = 4.78, p = 0.02). Additionally, achievement motivation was associated directly with female gender (β = 1.93, p = 0.03) and interest in nursing (β = 3.71, p = 0.005) and inversely associated with studying in the fourth academic year (β = −3.06, p = 0.03) and history of course drops (β = −3.45, p = 0.002).

Conclusion

Our study indicated that there was a direct significant relationship between happiness and achievement motivation in undergraduate nursing students. Therefore, officials and nursing education lecturers should consider programs to increase students' happiness, such as counseling or emotional support programs and workshops.

Measuring Happiness in Adolescent Samples: A Systematic Review

Background: Happiness is a phenomenon that relates to better mental and physical health and even longevity. There has been an increase in surveys assessing subjective well-being as well as happiness, one of the well-being components that reflect one’s feelings or moods. Happiness is mostly measured in adult samples. There is a lack of an overview of the tools used to evaluate adolescent happiness, so this paper aimed to review them. Methods: A literature search was performed in the PubMed and PsycArticles databases (2010–2019). In total, 133 papers met the eligibility criteria for this systematic review. Results: The results are grouped according to the type of measure, single or multiple items, that was used in a study. Almost half of the studies (64 of 133) evaluated subjective happiness using single-item measures. The most commonly used scales were the 4-item Subjective Happiness Scale and the Oxford Happiness Questionnaire. Among the 133 articles analyzed, 18 reported some validation procedures related to happiness. However, in the majority of cases (14 studies), happiness was not the central phenomenon of validation, which suggests a lack of happiness validation studies. Conclusions: Finally, recommendations for future research and for the choice of happiness assessment tools are presented.

The Association of Salivary Serotonin With Mood and Cardio-Autonomic Function: A Preliminary Report

BACKGROUND

Serotonin plays an important role in mood regulation and depression. However, it is not clear whether the levels of serotonin in saliva are related to current mood.

AIM

To test the association of salivary serotonin concentrations with mood, as well as cardiovascular and autonomic parameters.

MATERIALS AND METHODS

Saliva samples were obtained from collegiate runners and output parameters were examined before and after physical activity.

RESULTS

Salivary serotonin concentration was negatively associated with current mood (β = -0.32, 95%CI -0.62 to -0.02, p = 0.037, analysis adjusted for potential confounders), but insignificantly with measured cardiovascular and autonomic parameters.

CONCLUSIONS

Salivary serotonin may reflect current mood. The results are preliminary and require further evaluation.

Effect of Chief Executive Officer’s Sustainable Leadership Styles on Organization Members’ Psychological Well-Being and Organizational Citizenship Behavior

Situational leadership theory and the contingency approach of leadership were utilized and applied based on situational theory. Based on a total of four foundational theories, that is, bottom-up spillover theory, theories of prosocial behavior, and so on, this study empirically analyzed what influence a chief executive officer’s (CEO’s) sustainable leadership styles (servant, ethical, and authentic leadership) have on the psychological well-being and organizational citizenship behaviors of organization members. The study was conducted on adult employees of midsized or larger companies (including subsidiaries) across four countries: South Korea, the United Kingdom, the United States, and South Africa. Data were obtained from 649 adult employees. SmartPLS was used to conduct structural equation modeling analysis of the data. The results were as follows: (1) CEOs’ servant and authentic leadership styles had statistically significant positive (+) effects on employees’ psychological well-being; however, ethical leadership did not. (2) CEOs’ ethical leadership had a statistically significant (+) effect on employees’ organizational citizenship behavior; however, servant and authentic leadership did not. (3) Employees’ psychological well-being had a statistically significant (+) effect on organizational citizenship behavior. CEOs are attracting more attention than ever, leading companies in today’s rapidly changing times. This suggests that it is necessary to comprehend principles that show when, where, and how important leaders are and sustainable leadership styles that can increase their chances of success. Moreover, this study derived constructive implications that a leader can overcome today’s challenges through sustainable leadership styles.

Mental health and well-being of children in the Philippine setting during the COVID-19 pandemic

The coronavirus disease 2019 (COVID-19) pandemic has subjected the mental health and well-being of Filipino children under drastic conditions. While children are more vulnerable to these detriments, there remains the absence of unified and comprehensive strategies in mitigating the deterioration of the mental health of Filipino children. Existing interventions focus on more general solutions that fail to acknowledge the circumstances that a Filipino child is subjected under. Moreover, these strategies also fail to address the multilayered issues faced by a lower-middle-income country, such as the Philippines. As the mental well-being of Filipino children continues to be neglected, a subsequent and enduring mental health epidemic can only be expected for years to come.

Effects of the School-Based Integrated Health Promotion Program With Hydroponic Planting on Green Space Use and Satisfaction, Dietary Habits, and Mental Health in Early Adolescent Students: A Feasibility Quasi-Experiment

Background: School-based green space activities have been found to be beneficial to the physical activity level and lifestyle habits of adolescent students. However, their effects on green space use and satisfaction, mental health, and dietary behaviors required further investigation. This study aimed to investigate the effects of school-based hydroponic planting integrated with health promotion activities in improving green space use, competence and satisfaction, healthy lifestyle, mental health, and health-related quality of life (QoL) among early adolescent students in secondary schools.

Methods: This study adopted a three-group comparison design (one control and two intervention groups). Secondary school students (N = 553) of grades 7–9 participated in either (1) hydroponic planting (two times per week for 8 months) integrated with health promotion activities; (2) only health promotion activities (one time per week for 6 weeks); or (3) control group. Outcomes assessed by questionnaire included green space use and satisfaction, life happiness, lifestyle, depressive symptoms, and health-related QoL.

Results: After adjusting for sex and school grade, the scores in “green space distance and use” and “green space activity and competence” were significantly better in the intervention groups than in the control group. Hydroponic planting integrated with health promotion activities was also associated with better scores in dietary habits and resistance to substance use. Intervention groups had a higher score in “Green space sense and satisfaction” and life happiness when compared with the control group.

Conclusions: Our study shows that the school-based hydroponic planting integrated with health promotion activities were feasible and, to a certain extent, useful to improve green space use and competence, dietary habits, and resistance to substance use among early adolescent students in secondary schools in urban areas. Future studies should address the limitations identified, for example, designing a randomized controlled trial that could fit school schedules to generate new evidence for physical and mental health in adolescent communities.

Urban Adolescence: The Role of Neighbourhood Greenspace in Mental Well-Being

Mental health and well-being in adolescence are associated with many short- and long-term outcomes. The evidence suggests that greenspace may play a role in adolescents' mental well-being, but we do not know much about the specifics of this link. In this paper, we investigated the role of other factors in the association. In a cross-sectional study, we investigated the role of neighbourhood greenspace in emotional and behavioural outcomes in 11-year-old urban adolescents participating in the UK Millennium Cohort Study (n = 4,534). We used linear regression models to test for an association of greenspace with self-esteem, happiness, positive mood, negative mood, and antisocial behaviour. We also investigated effect modification/moderation by garden access, physical activity, and perceived area safety. We did not find a main effect of greenspace, but we did find interaction effects. First, in adolescents without a garden, higher levels of greenspace were associated with lower levels of self-esteem and positive mood. Second, in adolescents who reported lower levels of physical activity, higher levels of greenspace were associated with lower levels of negative mood. Third, in adolescents who perceived their areas to be unsafe, higher levels of greenspace were associated with higher levels of antisocial behaviour. Our findings suggest that merely more greenspace in the neighbourhood may not be sufficient to promote the mental well-being of urban adolescents in the UK. However, greenspace does seem to have an influence under certain conditions which should be investigated further in future studies.

Core self-evaluations and psychological well-being: the mediating role of work-to-family enrichment

Purpose

How or whether dimensions of work-to-family enrichment (WFE) mediate the relationship between an individual's core self-evaluations (CSEs) and their psychological well-being (PWB) is yet to be explained. The purpose of this study is to examine the role of three WFE dimensions in mediating between CSEs and PWB in Indian bank employees.

Design/methodology/approach

The present study collected data from 222 full-time bank employees working in Indian nationalized banks. The authors tested the study hypotheses using parallel mediation analysis.

Findings

The result showed positive associations among CSEs, all WFE dimensions (development, affect and capital-based) and PWB. Parallel mediation analysis suggested that two WFE dimensions (affect and capital-based) mediated the relationship between CSEs and PWB.

Research limitations/implications

The use of a single source of data (Indian nationalized banks) limits the generalizability of the findings.

Practical implications

Senior management at these banks may build a happier and more satisfied workforce by implementing appropriate training and personality development programs. Empowering and rewarding employees for the desired performances may help them appreciate their self-worth, enrich their quality of life (by gaining positive resources from work-family interactions) and ultimately improve their PWB.

Originality/value

The research literature has been relatively silent on the mediating role of individual dimensions of WFE. The present study adds to the existing body of knowledge by exploring the role of individual dimension-based WFE in the relationship between CSEs and PWB.

Psychological Impact of the Lockdown in Italy Due to the COVID-19 Outbreak: Are There Gender Differences?

The COVID-19 emergency has hit the whole world, finding all countries unprepared to face it. The first studies focused on the medical aspects, neglecting the psychological dimension of the populations that were forced to face changes in everyday life and in some cases to stay forcedly at home in order to reduce contagion. The present research was carried out in Italy, one of the countries hardest hit by the pandemic. The aim was to analyze the perception of happiness, mental health, and the sense of loneliness experienced by adults during the lockdown due to the COVID pandemic. Specifically, the variables will be examined in relation to gender difference, living alone, with partner, or with partner and children. The research followed a quantitative approach using an online questionnaire. The project involved 1100 subjects from whom 721 participants (75.5% women) were extrapolated. Of them, 17.3% claimed to live alone, 39.5% with their partner, and 43.1% with their partner and children. The results show that people in general experienced a lower level of happiness and mental health and higher levels of loneliness compared to normative sample. The lockdown and pandemic condition due to COVID-19 seems to have canceled the gender differences in the perception of happiness and mental health, while it seems to have increased the perception of loneliness experienced by males compared to the pre-pandemic condition. In addition, those who lived alone perceived a greater level of loneliness than those who lived with their partner or partner and children. Unexpectedly, no significant differences emerged regarding the level of happiness and mental health between those who had direct contact with the virus and those who did not. These data should make political decision-makers reflect on the need to pay more attention to the implications that such drastic measures as a lockdown can have on people's psychological well-being.

Adolescents' Bipolar Experiences and Suicide Risk: Well-being and Mental Health Difficulties as Mediators

Bipolar disorder is usually accompanied by a high suicide risk. The main aim was to identify the risk and protective factors involved in suicide risk in adolescents with bipolar experiences. Of a total of 1506 adolescents, 467 (31%) were included in the group reporting bipolar experiences or symptoms, 214 males (45.8%) and 253 (54.2%) females. The mean age was 16.22 (SD = 1.36), with the age range between 14 and 19. Suicide risk, behavioral and emotional difficulties, prosocial capacities, well-being, and bipolar experiences were assessed through self-report. Mediation analyses, taking gender as a moderator and controlling age as a covariate, were applied to estimate suicide risk. The results indicated that the effect of bipolar experiences on suicide risk is mediated by behavioral and emotional difficulties rather than by prosocial behavior and subjective well-being. Specifically, emotional problems, problems with peers, behavior problems, and difficulties associated with hyperactivity were the most important variables. This relationship was not modulated by gender. However, the indirect effects of some mediators varied according to gender. These results support the development of suicide risk prevention strategies focused on reducing emotional difficulties, behavioral problems, and difficulties in relationships with others.

Sources of academic stress among Iranian adolescents: a multilevel study from Qazvin City, Iran

Background

Academic stress can cause mental and physical problems and affect adolescents’ healthy development. This study aimed to estimate academic stress and explore its sources at the individual- and school levels among school-going adolescents in the city of Qazvin, Iran.

Results

This cross-sectional study used a stratified cluster sampling to recruit 1724 students aged 12–19 years from 53 schools in Qazvin City. Data were collected using a validated self-administered questionnaire. The mean academic stress score was 45.7 (95% CI 45.2, 46.3). The stress level was statistically higher among older 47.5 (95% CI 46.7, 48.3) than younger 44.1 (95% CI 43.4, 44.9) adolescents. The main academic stressors included: future uncertainty 69.7 (95% CI 68.8, 70.7), academic competition 58.5 (95% CI 57.3, 59.6), and interaction with teachers 56.1 (95% CI 55.3, 56.9). Gender, educational period, school type, family socioeconomic status, and father’s education were associated with academic stress.

Conclusions

We conducted a multilevel study using a random sample of male and female students in the city of Qazvin, Iran. Results indicated moderate levels of stress among Iranian adolescents. The academic stress was associated with several individual and school-level variables. Students and their families and teachers need education on stress prevention methods and coping mechanisms. Future research should focus on developing and testing multilevel policies and interventions to improve students’ mental health and academic performance.

Academic Stress and Adolescents Mental Health: A Multilevel Structural Equation Modeling (MSEM) Study in Northwest of Iran

Background: We aimed to determine the relation of different sources of academic stress and adolescents´ mental health through mediator variables on the student and school levels.

Study design: A cross-sectional study.

Methods: Overall, 1724 students aged 12-19 yr were selected from 53 high schools in Qazvin City, northwest instead of central Iran through stratified cluster sampling. The sources of academic stress include family conditions, education system, future concerns, academic competitions, interaction with teachers, school disciplines, peer pressure, parental involvement, and financial problems. Academic self-efficacy and self-concept were the mediator constructs. The students and schools´ information were considered on levels 1 and 2, respectively. A Multilevel Structural Equation Modeling (MSEM) analysis was done.

Results: High value of academic stress was associated with reduction of mental health. On the student level, the academic stress caused by the families 0.31 (95% CI: 0.28, 0.34), peers 0.29 (95% CI: 0.27, 0.32), and the education system 0.21 (95% CI: 0.18, 0.24) had the highest impact on the adolescentsˊ mental health, respectively. There was a direct and indirect relation between academic stress and mental health through the self-concept. On the school level, only family conditions stress had a relation with mental health (P=0.015, b=1.08). Academic self-efficacy showed no significant relation in the model.

Conclusion: The stress from the family is the most important source of stress associated with adolescent mental health. Self-concept unlike academic self-efficacy had an important mediating role in the relation between different sources of academic stress and adolescents' mental health.

Effects of a mental health promotion intervention on mental health of Iranian female adolescents: a school-based study

BACKGROUND

Poor mental health is common among adolescents. Given the increasing burden of poor mental health among adolescents in developing countries, it seems necessary to identify the effective interventions. The main purpose of this study was to investigate the effects of a school-based mental health promotion program (SMHPP) on mental health parameters among female adolescents in Tabriz, Iran.

METHOD

In this experimental study, a random sample of female high-school students of grade nine was recruited. The subjects were then randomly allocated to intervention (n = 145) and control (n = 139) groups. The three-stage SMHPP was designed based on the shortages and unmet needs of the students as reported in the pretest stage. All subjects in the intervention group were provided with a stress management skill training program of six sessions using McNamara Model. Coincided with making environmental changes, a joyful intervention program was carried out. After 2 months, post-test data were collected.

RESULTS

A total of 284 students completed their participation in the study. The groups did not differ in none of socio-demographic characteristics and mental health parameters, at baseline. The number of subjects reporting medium-level of happiness was increased by 32.6% among intervention group. Moreover, upon sign test and pre-post comparison, the group-wise distribution changed between the intervention and control groups for the parameters of life satisfaction (p ≤ 0.001) and psychological well-being (p ≤ 0.01).

CONCLUSION

The implementation of SMHPP as a low-cost, needs-based and multifaceted program, showed promise in promoting adolescents' mental health, particularly in the parameters of happiness, life satisfaction and psychological well-being. This was an important evidence for the development and implementation of interventions and policies in the field of mental health promotion among adolescents. Our work provided means for reducing burden of poor mental health among adolescents in a non-western cultural context. Further larger studies are required to evaluate the effectiveness of such school-based mental health promotion interventions in students.

Psychological well-being and happiness among Middle-aged women: A cross-sectional study

Biological, physical, and psychosocial changes that occur during the aging process can negatively impact women's mental health and happiness at midlife. In this cross-sectional study, we aimed to determine the level of psychological well-being and happiness among middle-aged women in Tabriz. Data were collected from December 2017 to February 2018 by face-to-face interviews, using structured questionnaires of happiness and psychological well-being. The participants were 40-60-year-old middle-aged women (n = 300) selected by clustered random sampling allocation. A total of 167 (55.7%) out of all the women had decreased levels of psychological well-being. Psychological well-being was found to be significantly lower among the women with low levels of happiness (B: 24.43, CI (18.57 to 30.29), p < 0.001). Health care centers should implement more comprehensive mental health promotion programs for middle-aged women, including free of charge recreational opportunities (e.g., walking, swimming, dancing) to improve psychological health and well-being.

Can I Sustain My Happiness? A Review, Critique and Research Agenda for Economics of Happiness

Human beings want to live in a state of happiness and prosperity, but happiness is important not just for the well-being of individuals but for the well-being of society. To ensure the maximization of happiness, it is necessary to consider more than just money, and rather include the right understanding of happiness at the individual level, the family level, the society level, and the environmental (nature) level. This paper contributes to the existing body of knowledge by consolidating the findings of the literature; grouping those into major themes and sub-themes; describing the mechanisms based on the empirical papers by highlighting the independent, dependent, control, and moderating variables, to study the causal relationships between variables under study; proposing an agenda for future research; and informing the policymakers about decisions influencing the human happiness level through legislative rules and regulations. Our results suggest prioritizing the conceptualization of happiness while computing the happiness level at the individual or collective levels. Furthermore, the study recommends governments to establish the conditions enabling individuals to report happiness independently from the political pressure to answer strategically for impressive happiness level figures at the macro level.

Evaluation of the relationships among happiness, stress, anxiety, and depression in pharmacy students

INTRODUCTION

To present the results of a survey on stress, anxiety, depression, subjective happiness, and academic satisfaction among pharmacy students.

METHODS

A total of 410 pharmacy students, were included. Sociodemographic characteristics, stress, anxiety and depressive symptoms, and happiness were evaluated using the Perceived Stress Scale (PSS), Hospital Anxiety and Depression Scale (HADS), and Subjective Happiness Scale (SHS), in May 2015.

RESULTS

First and second year student's (n = 200) presented higher levels of academic satisfaction (p = 0.003) and lower levels of stress (p < 0.001), anxiety (p = 0.011) and depression (p = 0.010) than third and fourth year students (n = 210). Academic satisfaction, HADS, and the PSS explained 36.7% of the students' happiness.

CONCLUSIONS

The student's psychological distress, academic satisfaction, and happiness varies through the school years. Monitoring a probable cumulative effect during pharmacy school may contribute to identify students at risk.

Relationship between happiness and tobacco smoking among high school students

OBJECTIVES

Recent research has described negative relationship between happiness and habitual smoking among adolescents. No study of this relationship has been conducted among Iranian adolescents. The aim of the present study was to characterize the relationship between happiness and cigarette or hookah smoking among a sample of high school students.

METHODS

A sample of 1,161 10th-grade students in Tabriz (northwest Iran) was selected by multi-stage proportional cluster sampling. Participants completed a self-administered multiple-choice questionnaire including information on cigarette smoking, hookah smoking, happiness score, substance abuse, self-injury, general risk-taking behavior, attitudes towards smoking, socioeconomic information, and demographic characteristics. An ordinal logistic regression model was used for data analysis.

RESULTS

It was found that 5.9 and 5.0% of students were regular cigarette smokers and regular hookah smokers, respectively. After controlling for potential confounders, higher happiness scores were found to protect students against more advanced stages of cigarette smoking (odds ratio [OR], 0.98; 95% confidence interval [CI], 0.97 to 0.99; p=0.013). However, no significant relationship was found between happiness scores and hookah smoking status (OR, 1.01; 95% CI, 0.97 to 1.02; p=0.523).

CONCLUSIONS

Happiness scores were associated with less advanced stages of habitual cigarette smoking among high school students. Our findings underscore the necessity of conducting longitudinal or interventional studies aiming to determine the effects of enhancing happiness on preventing the transition through the stages of cigarette and hookah smoking.

What determines psychological well-being among Iranian female adolescents? Perceived stress may overshadow all determinants

Background: Mental health problems, as one of the most neglected issues among adolescents,are common during adolescence and emerging adulthood. The aim of present study was to investigate the determinants of psychological well being among female adolescents in Tabriz,Iran.

Methods: In this cross-sectional study, multi-stage cluster sampling was employed to recruit 289 female high school students to participate in the study during 2013–2014. A 3-section questionnaire was applied to collect data. Hierarchical linear regression analysis was applied to illustrate the variations in psychological wellbeing score on the basis of socio-demographic and psychological variables.

Results: Self-efficacy, hopefulness, happiness and life satisfaction were positively correlated (r> 0.400) and perceived stress was negatively associated with psychological well-being (r =-0.689). In the first model, satisfaction with family lifestyle (β = 0.168, P < 0.001) and perceived stress (β = -0.470, P < 0.001) were the most significant positive and negative predictors for psychological wellbeing, respectively (R² = 0.595, P < 0.001). In the second model (step 6),physical activity (β = -0.109, P < 0.019), have/had boyfriend (β = 0.237, P < 0.001), hopefulness(β = -0.130, P < 0.05) and happiness (-β = 0.387, P < 0.001) were significant predictors for perceived stress (R² = 0.453, P < 0.001).

Conclusion: Considering the various behavioral, mental and social predictors of psychological wellbeing, it seems that perceived stress has overshadowed the influence of a majority of the other factors. Such influence may be due to the specific cultural and context-based rules enforced for female adolescents in the Iranian community.

Factor affecting happiness among nursing students in South Korea

WHAT IS KNOWN ON THE SUBJECT?: Despite the increased interest in nursing students' happiness in South Korea, few studies have attempted to identify factors influencing their happiness. Therefore, nursing educators should consistently investigate the factors influencing happiness and develop strategies to improve happiness among Korean nursing students. WHAT THIS PAPER ADDS TO EXISTING KNOWLEDGE?: This study confirmed that there were positive correlations between grateful disposition, social support and happiness. In addition, grateful disposition and support from intimate people were identified as predictors of happiness in Korean nursing students. WHAT ARE THE IMPLICATIONS FOR PRACTICE?: Development of intervention programmes to help nursing students increase grateful disposition and support from intimate people may be helpful for improving happiness. These programmes can include activity, such as writing a gratitude journal, and extracurricular programmes, such as mentoring programmes between seniors and juniors and/or professor and student.

ABSTRACT

Introduction Happiness is very important in the training and development of nursing students as future nurses. However, nursing students experience a high level of stress and low level of happiness in South Korea. Aim This study aimed to investigate factors that affect happiness among nursing students in South Korea. Method Data were collected from a total of 241 nursing enrolled in two 4-year baccalaureate nursing programmes in South Korea, using a self-administrated questionnaire. To identify predictors of happiness, stepwise regression analysis was conducted.
