RESUMO
Motorcycle safety remains a concern in low- and middle-income countries. This study addresses this issue by identifying hazardous scenarios for motorcyclists in Indonesia. We conducted a two-step cluster analysis and injury analysis to examine motorcycle accidents based on the police accident dataset (2020-2021) of Brebes Regency, Indonesia. We integrated the findings with accident self-reports from 104 young motorcyclists using a joint display to obtain a more comprehensive insight. As a result, we identified four hazardous traffic scenarios: motorcycle-to-vehicle collisions on median roads, motorcycle-to-vehicle collisions on non-median roads, motorcycle-to-pedestrian collisions, and single-motorcycle collisions. We suggest countermeasures for each scenario and propose a public transport policy as a safer mobility solution. Applying a two-step cluster analysis on accident data and integrating the findings of accident data and self-report analysis proved beneficial in this study. Therefore, we encourage the use of this novel approach in future studies.

A thorough and continuous investigation of the association between education and depression in Southeast Asia is critical, particularly in Indonesia, where depression is highly prevalent. Despite this, studies on education and depression mainly use a cross-sectional design alone, which cannot control the bidirectionality of the relationship. Therefore, this study investigated the longitudinal effects of education on depression symptoms, based on nationally representative survey data. This study used as its basis a longitudinal socioeconomic and health survey in Indonesia, the Indonesia Family Life Survey (IFLS). The survey collected data through face-to-face interviews with individual respondents and their families. The fourth and fifth waves of IFLS datasets were used in the analysis. A total number of 18,374 adult participants were included in the dataset. Depression symptoms were assessed based on a 10-item version of the CES-D (Center for Epidemiologic Studies Depression) Scale. Education level was the highest level of education attained by the participants. A cross-lagged longitudinal model was tested using structural equation modeling (SEM) or analysis of covariance structure. The results showed that the model of education and depression fits the data well. The fit indices of the model, χ2 (1, N = 18,374) = 21.592, p = 0.001, RMSEA = 0.033, CFI =. 0999, fulfilled the requirements for a good fit. Meanwhile, further analysis of the cross-lagged model revealed that education predicted depression and not the other way around. The standardized regression weights showed that higher education attainment reduces the risk of depression later in life. This study asserts that educational attainment has longitudinal effects on depression. Therefore, expanding the policies surrounding educational opportunity may prevent the onset of depression. This is important, especially in the Indonesian context, where the prevalence of depression among adults is higher than the global average. Access to further education deserves continued consideration in research and policy discussions on mental health and educational system development.

BACKGROUND: Mental health problems are associated with decreasing the quality of various aspects of life. Cases of mental health problems (e.g., depressive symptoms) have increased continuously. Researchers predicted depression to be the first cause of world burden diseases in 2030. One of the determinant factors of mental health is parents' education levels, but there have been contradictory research findings. The current research investigates the effect parental education attainment has on children's mental health. METHODS: We used public data from two waves of the Indonesia Family Life Survey (IFLS) conducted in 2007 and 2014. There were 767 participants aged 15-19 years old (M = 16.80, SD = 1.37) in 2007. All participants were re-interviewed in 2014. We examined the highest level of the parents' formal education in 2007 and the children's mental health in 2014 to find the longitudinal effects. We used depressive symptoms and happiness as representative variables of mental health. The structural equation model (SEM) was used to examine the hypothesis, and we prioritized predictive testing over the models' goodness of fit. We have built 12 models of combinations of children's and parents' sexes and different independent variables. RESULTS: The hypothesis testing showed the longitudinal effects that fathers' education in 2007 has on daughters' depressive symptoms in 2014 (ß = -.203, p < 0.01), while there were longitudinal effects from mothers' education in 2007 on their daughters' depressive symptoms (ß = -.163, p < 0.01) and sons' depressive symptoms (ß = .096, p ≤ 0.05) in 2014. Testing the happiness models showed that fathers' education in 2007 influenced the happiness of all of participants (ß = .167, p < 0.01), including both sons (ß = .206, p < 0.01) and daughters (ß = 149, p < 0.01). On the contrary, no significant correlation was found between mothers' education and children's happiness across all three categories of participants. CONCLUSIONS: The general results of this study showed that parents' education levels were associated with their children's mental health, but there are different associations found through the different combinations of children's and parents' sexes.

BACKGROUND: Studies on physical activity's psychological benefits are generally fewer than those on its physiological benefits, and these limited studies have mostly investigated its impact on cognitive functions. Studies exclusively investigating physical activity's effects on happiness are rare. This study aims to investigate the effect of physical activity on psychological functions, especially on happiness. METHODS: Analysis was based on a large field of nationally representative Indonesian adult data. Data were compiled based on face-to-face interviews with 12,051 adults. Participants provided measures of physical activity, subjective health, and happiness, and responses were recorded with computer-assisted personal interviewing (CAPI) software. Demographic data, including gender, subjective wealth, education, and age, were also included in the analysis. Structural equation modeling (SEM) was conducted to determine the relationship between physical activity, health, subjective wealth, and happiness. RESULTS: The tested model of the association between physical activity, health, subjective wealth, and happiness indicated a good fit, based on χ2 (1, n = 12,051) = 48.733, p = .001, RMSEA = .063, and CFI = .97. Path analysis results showed that health conditions mediated the effects of physical activity on happiness. The result also showed positive effects of education level and subjective wealth on happiness. CONCLUSION: This study provides evidence that engagement in physical activity has a positive impact on happiness. Indonesian adults should engage in more active lifestyles since more than one-third of Indonesians did not get enough physical activity.

BACKGROUND: Procrastination is a common problem in higher education. It leads to negative consequences on students' health and academic achievement. Nevertheless, research concerning interventions has not yet produced consistent results. This study aims to examine the effectiveness of a writing group program on reducing academic procrastination. METHODS: This study was a quasi-experimental study with a one-group pretest-posttest design using double pretests. A double pretest design was used to ensure the internal validity of the experiment. Twenty graduate students followed a 15-days writing group program consisted of a training session and four sessions of writing groups. A thesis procrastination scale was used to measure the intervention's effects. RESULTS: The writing group program helped students to set a writing target, discussed writing progress, and provided social support to their colleagues. The results showed that the intervention program could significantly decrease academic procrastination. CONCLUSION: The present study demonstrated that a writing group could potentially reduce academic procrastination. Thus, students could benefit from a writing group when working on their master thesis. A thesis preparation course that provides information about goal-setting strategy and the principles of effective writing habits (i.e., behavioral, artisanal, social and emotional habits), might also assist students in writing their thesis. Further research is needed, preferably through the provision of a control group, a randomized assignment and a larger sample.

PURPOSE: The aim of this paper is to provide evidence for the validity and reliability of a questionnaire for assessing the implementation of problem-based learning (PBL). This questionnaire was developed to assess the quality of PBL implementation from the perspective of medical school graduates. METHODS: A confirmatory factor analysis was conducted to assess the validity of the questionnaire. The analysis was based on a survey of 225 graduates of a problem-based medical school in Indonesia. RESULTS: The results showed that the confirmatory factor analysis model had a good fit to the data. Further, the values of the standardized loading estimates, the squared inter-construct correlations, the average variances extracted, and the composite reliabilities all provided evidence of construct validity. CONCLUSION: The PBL implementation questionnaire was found to be valid and reliable, making it suitable for evaluation purposes.
