Car emissions have significant detrimental environmental and health impacts, and many journeys could be undertaken using alternative transport. Effective transport policy necessitates identification of potentially modifiable determinants of driving. This thesis identified psychological underpinnings of decisions to drive. Study 1 used qualitative ‘grounded theory’ analysis to detail commuters’ reasons for driving, and highlighted misconceptions and biases underpinning these motives. In study 2, we developed quantitative measures of the concepts identified in study 1, and tested these as determinants of decisions to commute by public transport alongside variables from the Theory of Planned Behaviour (TPB; Ajzen, 1991). Results showed that the inductive concepts were best modelled as determinants of attitude and control perceptions, and demonstrated the superiority of established deductive concepts. A meta-analysis of the extant literature (study 3) showed a dearth of available evidence of correlates of driving. Strong associations with behaviour were found for intention and habit, and TPB cognitions relating to not driving showed stronger effects on intentions than did TPB variables relating to driving. There were also effects for descriptive and personal norms. Using an extended TPB model, study 4 demonstrated that the motivation to make local journeys by car was informed by cognitions relating to car and to non-car travel, and descriptive and personal norms. Environmental beliefs informed personal norms and attitudes to non-car travel. Studies 5-7 explored habit in commuting mode choice: study 5 developed a new self-report habit measure, which in studies 6 and 7 was used in comparison with existing habit indices to predict car and bicycle commuting among UK and Dutch samples respectively. Findings revealed the superiority of an existing habit measure, and pointed to the habitual nature of commuting mode choice. The seven studies highlighted motivational and volitional determinants of driving, and suggest various intervention strategies to reduce car use.

ObjectivesDepression and depressive symptoms are common mental disorders that have a considerable effect on patients’ health-related quality of life and satisfaction with medical care, but the prevalence of these conditions varies substantially between published studies. The aim of this study is to conduct a systematic review and meta-analysis to provide a precise estimate of the prevalence of depression or depressive symptoms among outpatients in different clinical specialties.DesignSystematic review and meta-analysis.Data sources and eligibility criteriaThe PubMed and PsycINFO, EMBASE and Cochrane Library databases were searched to identify observational studies that contained information on the prevalence of depression and depressive symptoms in outpatients. All studies included were published before January 2016. Data characteristics were extracted independently by two investigators. The point prevalence of depression or depressive symptoms was measured using validated self-report questionnaires or structured interviews. Assessments were pooled using a random-effects model. Differences in study-level characteristics were estimated by meta-regression analysis. Heterogeneity was assessed using standard χ2tests and the I2statistic. The study protocol has been registered with PROSPERO under number CRD42017054738.ResultsEighty-three cross-sectional studies involving 41 344 individuals were included in this study. The overall pooled prevalence of depression or depressive symptoms was 27.0% (10 943/41 344 individuals; 95% CI 24.0% to 29.0%), with significant heterogeneity between studies (p<0.0001, τ2=0.3742, I2=96.7%). Notably, a significantly higher prevalence of depression and depressive symptoms was observed in outpatients than in the healthy controls (OR 3.16, 95% CI 2.66 to 3.76, I2=72.0%, χ2=25.33). The highest depression/depressive symptom prevalence estimates occurred in studies of outpatients from otolaryngology clinics (53.0%), followed by dermatology clinics (39.0%) and neurology clinics (35.0%). Subgroup analyses showed that the prevalence of depression and depressive symptoms in different specialties varied from 17.0% to 53.0%. The prevalence of depression and depressive symptoms was higher among outpatients in developing countries than in outpatients from developed countries. Moreover, the prevalence of depression and depressive symptoms in outpatients slightly decreased from 1996 to 2010. Regarding screening instruments, the Beck Depression Inventory led to a higher estimate of the prevalence of depression and depressive symptoms (1316/4702, 36.0%, 95% CI 29.0% to 44.0%, I2=94.8%) than the Hospital Anxiety and Depression Scale (1003/2025, 22.0%, 95% CI 12.0% to 35.0%, I2=96.6%).ConclusionOur study provides evidence that a significant proportion of outpatients experience depression or depressive symptoms, highlighting the importance of developing effective management strategies for the early identification and treatment of these conditions among outpatients in clinical practice. The substantial heterogeneity between studies was not fully explained by the variables examined.

Indonesia is an agrarian country. Many Indonesians work as farmers. The agricultural sector has a great function in maintaining national food security, especially in maintaining the welfare of farmers. Interim data in 2013 show that the agricultural sector is in second position in contributing to GDP. With the existing data then the farmers should be able to live prosperous. But in reality farmers in Indonesia have problems that cause their quality of life is still far from the word worthy, such as low income and productivity, difficulties in credit applications, low education and irrigation systems that have not been optimal. Judging from the existing problems it is necessary to establish a management system that can overcome them. The purpose of this research is to optimize the potential of agricultural sector in Indonesia by using Sharia Agraria Management Organization (SAMO) by synergizing Baitul Mal Wa Tamwil (BMT) with Local Government and Central Government. This research was conducted by Meta Analysis method, based on observation and literature study, the authors conclude that with the existence of SAMO, farmers can improve their standard of living, increased productivity, and easy in the application of farming credit. It is expected that with this system can maintain the quality of the community environment and achieve the implementation of sustainable development.

We report a large meta-analysis of depression using data from the Million Veteran Program (MVP), 23andMe Inc., UK Biobank, and FinnGen; including individuals of European ancestry (n=1,154,267; 340,591 cases) and African ancestry (n=59,600; 25,843 cases). We identified 223 and 233 independent SNPs associated with depression in European ancestry and transancestral analysis, respectively. Genetic correlations within the MVP cohort across electronic health records diagnosis, survey self-report of diagnosis, and a 2-item depression screen exceeded 0.81. Using transcriptome-wide association study (TWAS) we found significant associations for gene expression in several brain regions, including hypothalamus (NEGR1, p=3.19x10-25) and nucleus accumbens (DRD2, p=1.87x10-20). 178 genomic risk loci were fine-mapped to find likely causal variants. We identified likely pathogenicity in these variants and overlapping gene expression for 17 genes from our TWAS, including TRAF3. This study sheds light on the genetic architecture of depression and provides new insight into the interrelatedness of complex psychiatric traits.

The Covid 19 pandemic forced all countries to adopt Social Distancing policies to prevent the spread of the virus. The perceived impact is the change in the dynamics of people's daily lives, where this change from being accustomed to socializing to having to be alone, from interacting to isolating. Teenagers are the most felt part of the impact of this Social Distancing, ranging from school at home, sports at home, gathering at home all activities done at home, this results in the onset of stress due to monotonous and boring activities. Therefore a strategy is needed to overcome the effects of the Covid Pandemic 19. This research method is a literature study, meta-analysis that is analyzing in-depth research journals related to Coping and Covid-19 Pandemic, articles-articles sourced from reputable journal journalists including Scopus including http://link.springer.com, http://seacrh.proquest.com, http://onlinelibrary.wiley.com ,and http://tandfonline.com. The research results show that Coping Strategy is a way for someone to overcome the problems that occur in him, Coping is very adaptive and can be incorporated into the cultural values of each Individual such as the values of spiritual beliefs, thinking patterns and strengths that exist in yourself and the environment. The conclusion is trying to adapt the results of several studies on Coping to deal with Pandemic by combining the cultural potential that exists in Indonesia. This research suggestion is still theoretical, and can be continued in field research

The influence of digital media on personal and social well-being is a question of immense public and academic interest. Scholars in this domain often use retrospective self-report measures of the quantity or duration of media use as a proxy for more objective measures, but the validity of these self-report measures remains unclear. Recent advancements in log-based data collection techniques have produced a growing collection of studies indexing both self-reported media use and device-logged measurements. Herein, we report a meta-analysis of this body of research. Based on 104 effect sizes, we found that self-reported media use was only moderately correlated with device-logged measurements, and that these self-report measures were rarely an accurate reflection of logged media use. These results demonstrate that self-reported measures of the quantity or duration of media use are not a valid index of the amount of time people actually spend using media. These findings have serious implications for the study of media use and well- being, suggesting that cautiousness is warranted in drawing conclusions regarding media effects from studies relying solely on self-reported measures of media use.

AbstractBackgroundDepression is a common post-stroke complication. Pre-stroke depression may be an important contributor, however the epidemiology of pre-stroke depression is poorly understood. Using systematic review and meta-analysis, we described the prevalence of pre-stroke depression and its association with post-stroke depression.MethodsWe searched multiple cross-disciplinary databases from inception to July 2017 and extracted data on the prevalence of pre-stroke depression and its association with post-stroke depression. We assessed the risk of bias (RoB) using validated tools. We described summary estimates of prevalence and summary odds ratio (OR) for association with post-stroke depression, using random-effects models. We performed subgroup analysis describing the effect of depression assessment method. We used a funnel plot to describe potential publication bias. The strength of evidence presented in this review was summarised via ‘GRADE’.ResultsOf 11 884 studies identified, 29 were included (total participantsn= 164 993). Pre-stroke depression pooled prevalence was 11.6% [95% confidence interval (CI) 9.2–14.7]; range: 0.4–24% (I295.8). Prevalence of pre-stroke depression varied by assessment method (p= 0.02) with clinical interview suggesting greater pre-stroke depression prevalence (~17%) than case-note review (9%) or self-report (11%). Pre-stroke depression was associated with increased odds of post-stroke depression; summary OR 3.0 (95% CI 2.3–4.0). All studies were judged to be at RoB: 59% of included studies had an uncertain RoB in stroke assessment; 83% had high or uncertain RoB for pre-stroke depression assessment. Funnel plot indicated no risk of publication bias. The strength of evidence based on GRADE was ‘very low’.ConclusionsOne in six stroke patients have had pre-stroke depression. Reported rates may be routinely underestimated due to limitations around assessment. Pre-stroke depression significantly increases odds of post-stroke depression.Protocol identifierPROSPERO identifier: CRD42017065544

Objective: Peer social functioning difficulties characteristic of ADHD persist into adolescence, but the efficacy of interventions for this age group remains unclear. Method: A systematic search of nonpharmacological interventions for adolescents with ADHD (10–18 years) identified 11 trials addressing social functioning, of which eight were included in meta-analyses. Results: Random effects meta-analyses of four randomized trials found no differences in social functioning between treatment and control groups by parent- ( g = −0.08 [−0.34, 0.19], k = 4, N = 354) or teacher-report ( g = 0.17 [−0.06, 0.40], k = 3, N = 301). Meta-analyses of nonrandomized studies indicated participants’ social functioning improved from baseline to postintervention by parent-report, but not teacher- or self-report. All trials had a high risk of bias. Conclusion: These results highlight the paucity of research in this age group. There is little evidence that current interventions improve peer social functioning. Clearer conceptualizations of developmentally relevant targets for remediation may yield more efficacious social interventions.

Advances in digital technology have put music libraries at people’s fingertips, giving them immediate access to more music than ever before. Here we overcome limitations of prior research by leveraging ecologically valid streaming data: 17.6 million songs and over 662,000 hr of music listened to by 5,808 Spotify users spanning a 3-month period. Building on interactionist theories, we investigated the link between personality traits and music listening behavior, described by an extensive set of 211 mood, genre, demographic, and behavioral metrics. Findings from machine learning showed that the Big Five personality traits are predicted by musical preferences and habitual listening behaviors with moderate to high accuracy. Importantly, our work contrasts a recent self-report-based meta-analysis, which suggested that personality traits play only a small role in musical preferences; rather, we show with big data and advanced machine learning methods that personality is indeed important and warrants continued rigorous investigation.

ObjectivesIt has often been suggested that screen work (ie, work on desktop, laptop, notebook or tablet computers) is a risk factor for neck and upper extremity symptoms. However, an up-to-date overview and quantification of evidence are lacking. We aimed to systematically review the association of exposure to screen work with neck and upper extremity symptoms from prospective studies.MethodsAn electronic database search (PubMed, Embase, Cinahl and Scopus) for prospective studies on the association of exposure to screen work and musculoskeletal symptoms was conducted. Studies were synthesised regarding extracted data and risk of bias, and meta-analyses were conducted.ResultsAfter screening 3423 unique references, 19 articles from 12 studies (with 18 538 participants) were included for the current review, with the most recent exposure assessment reported in 2005. Studies described duration and input frequency of screen work (ie, computer, keyboard and mouse use, assessed using self-reports or software recordings) and musculoskeletal symptoms (ie, self-reported neck/shoulder and distal upper extremity symptoms and diagnosed carpal tunnel syndrome [CTS]). Although there was overall an increased occurrence of musculoskeletal symptoms with larger exposure to screen work (relative risk: 1.11 [1.03 1.19]), findings were rather inconsistent with weaker (and statistically non-significant) risks when screen work was assessed by software recording (1.05 [0.91 1.21]) compared to with self-report (1.14 [1.03 1.19]).ConclusionsWe found an increased risk of musculoskeletal symptoms with screen work. However, the evidence is heterogeneous, and it is striking that it lacks information from contemporary screen work using laptop, notebook or tablet computers.
