A systematic review of country-specific drivers and barriers to household food waste reduction and prevention.

Food waste is a global challenge that threatens the sustainable development of human societies. Although food waste is produced in all stages of the food supply chain, household food waste is the biggest contributor to the food waste fraction. In this research, we systematically reviewed 54 empirical studies to explore drivers and barriers to household food waste reduction and prevention. Key aspects, such as comprehension and perception of food waste issues, practices and lifestyles, were examined. Our findings suggest that a great understanding of the impact of one's food waste on health, environment and economy directly promotes food waste management. Additionally, the food waste issue is not attributed to a single factor, it may differ varies across countries. The majority of the reviewed literature on household food waste comes from European countries, where similar geographical, economic and cultural characteristics may lead to comparable drivers and barriers. This could be the reason for showing optimistic experience to the respective food waste management interventions. However, the applicability of these findings and interventions to regions beyond Europe are uncertain. Future studies should also be expanded to include regions such as Asia, North America, Africa, Oceania, Latin America and the Caribbean. To support the sustainable management of household food waste, mapping country-specific food waste determinants is crucial in developing easy-to-implement food waste interventions that can specifically address the food waste issue in each country.

Parenting Practices and Adolescents' Mental Health: The Mediating Role of Perceived Maternal and Paternal Acceptance-Rejection and Adolescents' Self-Efficacy.

Parenting practices are essential in promoting children's mental health, especially in effective and ineffective parenting. The use of ineffective parenting practices is no longer encouraged in the west; however, it remains a common practice among Asian households. Ineffective parenting consists of inconsistent discipline, corporal punishment, and poor monitoring which may result in mental health consequences. Thus, this study assessed the mediating effects of adolescents' self-efficacy and parental acceptance-rejection on the relationship between ineffective parenting practices and adolescents' mental health. The current study involved a total of 761 school-going Malaysian adolescents aged 13-18 (38.5% males; Mage = 15.65; SDage = 1.43). This study utilized a cross-sectional design where it measured adolescents' mental health, ineffective parenting practices, parental acceptance-rejection, and adolescents' self-efficacy. Both paternal and maternal parenting practices and acceptance-rejection were measured independently. Adolescents' self-efficacy and perceived paternal and maternal acceptance-rejection were found to be significant mediators for ineffective parenting practices and adolescents' mental health. Our findings suggest that ineffective parenting practices will result in perceived parental rejection and lower self-efficacy which in turn resulted in poorer mental health among adolescents. It means parents should be mindful of their parenting approaches as they have a direct and indirect impact on the mental health of their offspring.

Social media skepticism and belief in conspiracy theories about COVID-19: the moderating role of the dark triad.

The prevalence of conspiracy theories about COVID-19 in the wide-open social media environment has raised considerable concerns about the adverse effects of believing such theories. The previous work showed that skepticism is negatively associated with acceptance of media content. However, this association has yet to be investigated between skepticism towards content on social media and conviction of COVID-19 conspiracy theories. Furthermore, this association can be a function of social media users' dark triad traits comprising Machiavellianism, narcissism and psychopathy. A convenient sample of 439 Malaysian young adult social media users was recruited to complete the survey. Results showed that skepticism has a negative relationship with belief in conspiracy theories about COVID-19. However, the strength of the relationship is varied depending on respondents' Machiavellianism and narcissism levels. The negative association between skepticism and belief in COVID-19 conspiracy theories is weaker for individuals with high scores on Machiavellianism. High and moderate scores on narcissism were also found to diminish the negative relationship of skepticism with COVID-19 conspiracy ideation. The results yield implications for enhancing healthy skepticism to mitigate belief in conspiracy theories promulgated on social media. Nonetheless, Machiavellianism and narcissism appeared to weaken the power of skepticism on conspiracy theories.

A Moderated Mediation Model of Perceived Effect of Fitspiration Images on Self: The Influence of Media Literacy and BMI.

The present study investigated the relationship between internal locus of control and the perceived impact of Instagram fitspiration images on the self with media literacy as the mediating role in this relationship. This study also examined the importance of body mass index (BMI) as a moderating factor in the mediated model, where higher BMIs could weaken the relationship between internal locus of control and the perceived effect of fitspiration images mediated through media literacy. A sample of 321 Malaysian university students who were fitspiration viewers filled out a self-report questionnaire assessing internal locus of control, media literacy, perceived effect of fitspiration images on self, body satisfaction and BMI. The data analysis was performed using SPSS PROCESS macro. Results show that internal locus of control is negatively associated with the perceived impact of fitspiration images on self, mediated by media literacy. However, BMI moderates the mediated relationship such that the negative relationship between internal locus of control and the perceived effect of fitspiration images through media literacy does not exert an effect on those with high BMI. These results accentuate the value of incorporating a potential mediator and moderator into the direct relationship between internal locus of control and perceived effect of media ideals on self to provide an enhanced understanding of this process and offer practical insights about the protective role of media literacy and negative effects of high BMI.

The Mediating Influence of the Unified Theory of Acceptance and Use of Technology on the Relationship Between Internal Health Locus of Control and Mobile Health Adoption: Cross-sectional Study.

BACKGROUND: Mobile health (mHealth) as an innovative form of information and communications technology can efficiently deliver high-quality health care by enhancing communication and health management, reducing costs, and increasing access to health services. An individual's internal health locus of control (HLOC) is found to be associated with the behavioral intent to adopt mHealth. However, little is known about the underlying mechanism of this association. OBJECTIVE: The primary objective of this study was to test the mediation influence of the Unified Theory of Acceptance and Use of Technology (UTAUT) on the relationship between internal HLOC and the behavioral intention to use mHealth. METHODS: A total of 374 responses were collected from Malaysian adult users of mHealth, using convenience and snowball sampling methods. Partial least squares structural equation modeling was used to analyze the data. Data were collected for variables, including demographics, internal HLOC, and modified UTAUT constructs (ie, performance expectancy, effort expectancy, and social influence). RESULTS: The results showed that there was no direct relationship between internal HLOC and the behavioral intention to use mHealth (ß=-0.039, P=.32). The indirect relationship between internal HLOC and the intent to adopt mHealth was supported, indicating that the UTAUT constructs performance expectancy (ß=0.104, P<.001), effort expectancy (ß=0.056, P=.02), and social influence (ß=0.057, P=.002) mediated this relationship. The results showed full mediation, with total variance explained at 47.2%. CONCLUSIONS: This study developed an integrative model, where a health-related disposition (internal HLOC), mHealth-related beliefs (performance expectancy and effort expectancy), and normative pressure (social influence) were combined to explain the underlying mechanism of the behavioral intent to adopt mHealth. The results showed that the intention to adopt mHealth is mediated by the influence of UTAUT factors, while HLOC has no direct effect on adoption intention. The findings provide insights into augmenting mHealth adoption among the public by enhancing the perceived benefits of mHealth, helping design more effective and user-friendly mHealth tools, and capitalizing on social normative influence to adopt mHealth. This study utilized the constructs of the UTAUT model to determine the intention to use mHealth. Future research should focus on other health- and technology-related theories to ascertain other possible factors influencing the behavioral intent of mHealth adoption.

Private Self-Consciousness and Self-Monitoring on Instagram: The Mediating Effect of Internal Locus of Control and Self-Concept.

Past studies examining the direct relationship between private self-consciousness and online self-presentation behavior have not met with much success. The aim of this study was to examine the direct relationship between private self-consciousness and self-monitoring as well as the indirect relationship between these two variables through the mediation of locus of control and self-concept among Instagram users. Besides investigating locus of control and self-concept independently, serial mediation of locus of control and self-concept in the relationship between private self-consciousness and self-monitoring was also examined. A sample of 309 university students was conveniently drawn from three private universities in Kuala Lumpur, Malaysia. Participants completed a survey that collected data on private self-consciousness, internal locus of control, self-concept, self-monitoring on Instagram and relevant demographic data. Results of this study showed that there is no direct relationship between private self-consciousness and self-monitoring on Instagram. Independently, locus of control was found to mediate the relationship between private self-consciousness and self-monitoring while self-concept did not. The serial-multiple mediation test supported the mediating role of locus of control and self-concept on this relationship. These indirect relationships contribute to our understanding of the underlying mechanism through which private self-consciousness influences self-monitoring on Instagram.

Psychometric Evaluation of the Malay Version of the Family Adaptability and Cohesion Evaluation Scale III for Malaysian Adolescents.

The Family Adaptability and Cohesion Scale III (FACES-III) has been widely used to measure an individual's family functioning in terms of cohesion and adaptability. In Malaysia, the FACES-III has been translated into the Malay language for the community, but its psychometric properties in this context remain unknown. Thus, the purpose of this research is to examine the psychometric properties of the Malay version of the FACES-III in 852 adolescents attending secondary schools in Kuala Lumpur, Malaysia. Data were randomly split into two halves: the exploration sample and the validation sample. Exploratory factor analysis was conducted on the exploration sample and a two-factor model was discovered after removing nine items that showed low factor loading. Then, confirmatory factor analysis was conducted on the validation sample to compare the one-factor models, two-factor models, and three-factor models. Results showed that the 11-item two-factor model (FACES-III-M-SF) was superior to the other competing models. Both the exploratory and confirmatory factor analyses replicated the two-factor structure of the original version of FACES-III. The reliability of the overall scale was consistently good, but the subscale results were mixed. This suggests that researchers should use the overall score, but not the subscale scores, in analyses.

Self-efficacy as a mediator of the relationship between parental closeness and suicidal ideation among Malaysian adolescents.

BACKGROUND: Suicide has become a serious worldwide mental health problem, including Asian countries. Suicidal ideation happens prior to the actual suicidal behaviour; thus, identifying the roots of suicidal ideation is vital. This study investigated the relationships between parental closeness, self-efficacy and suicidal ideation among adolescents in Malaysia. The mediation effect of self-efficacy on the relationship between parental closeness and suicidal ideation was also examined. METHOD: A total of 684 school-going adolescents aged 14-17 years old were recruited via multistage cluster sampling. Bivariate analysis was conducted using Pearson's correlation analysis. The mediation model was tested using SPSS macro developed by Preacher and Hayes. RESULTS: The results showed that mother closeness, father closeness and self-efficacy had significant negative correlation with suicidal ideation. Specifically, self-efficacy emerged as a partial mediator in the relation between mother closeness and suicidal ideation. Self-efficacy also fully mediated the relationship between father closeness and suicidal ideation. CONCLUSIONS: The findings implied that mother closeness had stronger correlation with adolescents' suicidal ideation compared to father closeness, while self-efficacy plays an important role in the relationship between parental closeness and suicidal ideation. Prevention and intervention efforts by practitioners dealing with adolescents' mental health issues, specifically on suicidal ideation, should seriously consider providing them with skills to enhance mother-adolescent relationship and their self-efficacy.
