Effect of the "Art Coloring" Online Coloring Game on Subjective Well-Being Increase and Anxiety Reduction During the COVID-19 Pandemic: Development and Evaluation.

BACKGROUND: COVID-19 has spread worldwide and generated tremendous stress on human beings. Unfortunately, it is often hard for distressed individuals to access mental health services under conditions of restricted movement or even lockdown. OBJECTIVE: The study first aims to develop an online digital intervention package based on a commercially released coloring game. The second aim is to test the effectiveness of difference intervention packages for players to increase subjective well-being (SWB) and reduce anxiety during the pandemic. METHODS: An evidence-based coloring intervention package was developed and uploaded to an online coloring game covering almost 1.5 million players worldwide in January 2021. Players worldwide participated to color either 4 rounds of images characterized by awe, pink, nature, and blue or 4 rounds of irrelevant images. Participants' SWB and anxiety and the perceived effectiveness of the game in reducing anxiety (subjective effectiveness [SE]) were assessed 1 week before the intervention (T1), after the participants completed pictures in each round (T2-T5), and after the intervention (T6). Independent 2-tailed t tests were conducted to examine the general intervention (GI) effect and the intervention effect of each round. Univariate analysis was used to examine whether these outcome variables were influenced by the number of rounds completed. RESULTS: In total, 1390 players worldwide responded and completed at least 1 assessment. Overall, the GI group showed a statistical significantly greater increase in SWB than the general control (GC) group (N=164, t162=3.59, Cohen d=0.59, 95% CI 0.36-1.24, P<.001). Compared to the control group, the best effectiveness of the intervention group was seen in the awe round, in which the increase in SWB was significant (N=171, t169=2.51, Cohen d=0.39, 95% CI 0.10-0.82, P=.01), and players who colored all 4 pictures had nearly significant improvements in SWB (N=171, F4,170=2.34, partial ŋ2=0.053, P=.06) and a significant decrease in anxiety (N=171, F4,170=3.39, partial ŋ2=0.075, P=.01). CONCLUSIONS: These data indicate the effectiveness of online psychological interventions, such as coloring games, for mental health in the specific period. They also show the feasibility of applying existing commercial games embedded with scientific psychological interventions that can fill the gap in mental crises and services for a wider group of people during the pandemic. The results would inspire innovations to prevent the psychological problems caused by public emergencies and encourage more games, especially the most popular ones, to take more positive action for the common crises of humankind.

Effects of COVID-19 on China's rape industry and strategies

To effectively cope with the shock of COVID-19 and its subsequent impact, and to promote stable and healthy development of rape industry, this paper systematically analyzed the impact of COVID-19 on China's rape industry. It includes perspectives of farmer's life, rape production and rapeseed processing enterprises, based on micro survey data provided by the National Rapeseed Industrial Technology System. The results showed that in terms of farmers' life, only 0.98% of the respondents were in a shortage of edible vegetable oil and 76.06% of them reflected no impact or a little impact on total household income. However, rural tourism decreased by 10.24 percentage points, and honey collecting behavior of bee farmers decreased by 4.6 points. On field production, 85.47% of the respondents reported "no change" and "small reduction" in field management workload, 90.38% reflected "no impact" and "a littlel impact" on rapeseed production employment, 79.06% considered "overall stability" in the price of agricultural materials, and 98.48% believed that it had a little impact on final output. However, the pest reporting rate increased by 4.99 points than last season. On rapeseed processing, it varied from region to region on the rapeseed processing enterprises' resumption rate, starting-up rate, specific difficulties faced by enterprises and government policies. Based on these results, future strategies should be taken to ensure improving development of rape industry. The strategies should include perfect construction of China's oil reserve system, more attention to diversification of imports, more innovation and technology promotion, optimization on marketing system and construction of information platform, and a"package"subsidy plan for the industry.
