ISSN 18688527

Objectives: This study aimed to evaluate the effectiveness of the Intervention program of Mindfulness and Compassion against COVID-19 (IMACOCO), an online mindfulness-based intervention (MBI), in enhancing mindfulness, mental health, well-being, and productivity among working individuals during the COVID-19 pandemic. Additionally, the study examined the program’s efficacy in individuals directly impacted by the pandemic through a randomized controlled trial and pre-post program comparisons. Method: Three hundred working adults, including office workers, educators, and medical welfare workers, were randomly allocated to the intervention or waiting control group. An 8-week online MBI program, with pre-, interim (4 weeks), and post-program (8 weeks) evaluations, was conducted via the Internet; standardized questionnaires were used to assess mindfulness, psychological distress, life satisfaction, and productivity. After the initial 8-week program, the waiting control group participated in the same program and evaluation surveys for pre-post comparisons. Results: There were 99 participants in the intervention group and 111 in the control group. Significant increases in mindfulness (FFMQ) and life satisfaction (SWLS) as well as decrease in psychological distress (GHQ-12) were observed primarily in the intervention group (Cohen’s d = 0.18–0.52). Furthermore, the pre-post comparisons with 168 participants demonstrated significant improvements in productivity (Cohen’s d = 0.26), and stratified analysis revealed that participants affected by COVID-19 showed more pronounced benefits in mindfulness and life satisfaction than those who were unaffected. Conclusions: Implementing an online MBI program (IMACOCO) can be a potent strategy to reduce mental stress and enhance overall well-being and resilience, in a disaster-prone world. Preregistration: This study is not preregistered.

The role of conflict and idea acceptance on the relationship between feedback and team creative behaviour

Akaki M., Maeno T.

Creativity and Innovation Management (Creativity and Innovation Management) 2024

ISSN 09631690

This study indicated the role of conflict and idea acceptance on the relationship between feedback and team creative behaviour. We focused on the team's contextual factors affecting team creative behaviour instead of the behaviour of individuals between the specific hierarchical level in the organizations. We surveyed 535 practitioners in Japanese firms and quantitatively examined the result through hierarchical multiple regression analysis. The results show the positive direct effect of feedback on team creative behaviour and the mediation effects of conflict and idea acceptance on the relationship between feedback and team creative behaviour, which were identified regardless of the creative process. On the other hand, conflict negatively moderated the feedback-team creative behaviour relationship only in the idea-generation phase. This study contributes to team creativity studies by clarifying the effect of conflict, which had contradictory findings in the previous research. In addition, shedding light on idea acceptance within the teams is another contribution since limited studies are focusing on it. The results offer implications to practitioners by giving suggestions to effectively provide and react to feedback within the teams by managing conflicts that have both positive and negative effects on creativity and accepting each other's ideas, which move the idea forward.

A Japanese Version of the Personal Relative Deprivation Scale (J-PRDS): Development and validation of the J-PRDS

Ohno H., Masuda S., Maeno T.

Current Psychology (Current Psychology) 42 ( 18 ) 15465 - 15474 2023.06

ISSN 10461310

This study developed and validated a 5-item Japanese translation of the Personal Relative Deprivation Scale (J-PRDS5), originally developed in English by Callan et al. Personality and Social Psychology Bulletin, 34, 1514–1529, (2008), Callan et al. Journal of Personality and Social Psychology, 101, 955–973, (2011) to measure feelings of resentment and dissatisfaction stemming from the belief that one has been deprived of a desired or deserved outcome as compared to others similar to them. Most studies on feelings of personal relative deprivation (PRD) have included Western participants and no such studies have been conducted in Japan. To bridge this gap, we conducted a factor analysis of the J-PRDS5’s items, which demonstrated a single-factor structure consistent with Western studies. Through validation of the scale for Japan, our version (J-PRDS5) exhibited high internal consistency. In contrast to feelings of PRD, subjective socioeconomic status (SSS) focuses on cognitive appraisals by comparing oneself to all people in the same society. Higher J-PRDS5 scores were significantly and negatively correlated with SSS, and lower J-PRDS5 scores and higher SSS scores were significantly correlated with higher self-esteem, general health, and subjective well-being (SWB). Based on a mediation analysis, we found that PRD mediated the relationship between SSS and self-esteem, general health, and SWB. Our study is the first to assess individuals’ feelings of PRD in Japan, and our findings suggest that reducing feelings of PRD may improve individuals’ health and happiness.

Feelings of Personal Relative Deprivation and Subjective Well-Being in Japan

Ohno H., Lee K.T., Maeno T.

Behavioral Sciences (Behavioral Sciences) 13 ( 2 ) 2023.02

Personal relative deprivation (PRD) refers to emotions of resentment and dissatisfaction caused by feeling deprived of a deserved outcome compared to some reference. While evidence suggests that relative deprivation based on objective data such as income affects well-being, subjective PRD has been less explored, especially in the East. This study evaluated the relationship between PRD and subjective well-being based on various aspects in the context of Japan. An online questionnaire survey, including the Japanese version of the Personal Relative Deprivation Scale (J-PRDS5) and various well-being indices, was administered to 500 adult participants, balanced for sex and age. Quantitative data analysis methods were used. PRD significantly correlated with subjective well-being as assessed by various aspects. Through mediation analysis, we found that a strong tendency to compare one’s abilities with others may undermine subjective well-being through PRD. The results also indicated that well-developed human environments may be associated with the maintenance of subjective well-being levels, even when PRD is high. Toward developing future interventions to improve well-being and health, efforts must be undertaken in Japan to monitor PRD and further clarify the mechanism of the association between PRD and the factors that showed a strong relationship in this study.

THE SYSTEMATIC FEEDBACK METHOD FOR IDEATION MODE IN WORKSHOPS

Akaki M., Maeno T.

Proceedings of the Design Society (Proceedings of the Design Society) 3 3523 - 3532 2023

To encourage creativity through ideation mode in design thinking, we conducted three workshops dealing with regional challenges with 44 participants. The systematic feedback method applied to the workshops supports the multi-disciplinary participants to feedback during the ideation mode to diverge ideas from diverse perspectives. The method is composed of feedback cards and the process of using them. Two kinds of cards encourage communication within the team. The next three cards aim to diverge the viewpoints of the feedback systematically to support the team to imagine the possibility of the idea evolving from a bird's eye view. Through quantitative analysis of the survey, we identified the significant and positive correlations between acceptance of the team's idea and team creativity, the effectiveness of the method on team creativity, and the team's characteristics that firmly realized the effect of the method. By categorizing the free comments, we indicated the valid functions and improvements that need further research in the future. Identified valid functions were not only diverging minds and perspectives but encouraging communication and understanding of the team members leading to acceptance and creativity.

Research paper (scientific journal), Joint Work, Accepted

Background: Materialism indicates the extent to which an individual’s life is focused on consumerism, or the acquisition of money and possessions. The Material Values Scale (MVS), comprising the factors “success,” “centrality,” and “happiness,” is a well-known rating scale for materialism. However, a Japanese version of the materialism scale has not yet been established, and the details of the factors and effects related to materialism have not yet been clarified in Japan. The purpose of this study is to develop and evaluate the Japanese version of the MVS (J-MVS). Methods: We developed the translated J-MVS using a back-translation process. To validate and evaluate the scale based on an online survey, we recruited 500 people, with 100 participants (50 men, 50 women) in five age groups, from 20 to 69 years. We compared and evaluated several factor structure models based on exploratory and confirmatory factor analysis. To evaluate the external criterion-referenced validity of the developed J-MVS scale, we examined the relationship between age, personality, and well-being, which have shown stable relationships with materialism in previous studies. Results: We developed two six-item dual-factor models. Both models showed significant positive correlations with social comparison orientation and neuroticism, and had significant negative correlations with various subjective well-being indices, suggesting sufficient external criterion-referenced validity. The J-MVS comprising six positive-worded items (J-MVS-P6; without any reverse-worded items) showed a higher correlation with other indicators than the version comprising six items representing all item types and was considered to have higher external criterion-referenced validity. Conclusions: We propose the J-MVS-P6 for use as a materialism scale in Japan. Compared with the findings from other countries, materialism in Japan may be more closely related to subjective well-being. This scale may be used to examine the effectiveness of various intervention methods for improving individuals’ happiness, based on changes in factors closely related to materialism in Japan.

Objective This study aimed to identify associations between multimorbidity and subjective health outcomes among the very old persons, after adjusting for coexisting conditions such as frailty and depression. Study setting and participants This was an observational cross-sectional study involving 1012 independent, community-dwelling very old persons (507 men, 505 women; aged 85-89 years) in Kawasaki city, Japan. Outcome measures The primary outcome was the cross-sectional associations between multimorbidity and poor self-rated health (SRH) and life satisfaction using binary logistic regression. The secondary outcome was the association of subjective health with each chronic condition. Results The prevalence of multimorbidity (≥2 conditions) was 94.7%, and the average number of chronic conditions was 4.47±1.9. Multimorbidity was significantly associated with poor SRH in the adjusted model only when six or more chronic conditions were present (OR 4.80; 95% CI 1.34 to 17.11; p=0.016). Cerebrovascular disease, heart disease, respiratory disease, connective tissue disease and arthritis showed significant associations with poor SRH after multivariate adjustment. Sex-specific analysis replicated associations between multimorbidity with six or more conditions and SRH in both men and women, while the diseases with the greatest impact on SRH differed between men and women. Most conditions were not associated with low satisfaction with life scale, with the exception of arthritis (OR 1.92, 95% CI 1.32 to 2.78, p=0.001). Conclusions Multimorbidity is prevalent in the independent, community-dwelling very old persons and is associated with poor SRH when six or more conditions are present; conditions causing mobility limitations, such as cerebrovascular disease, connective tissue disease and arthritis, have a negative impact on SRH. Trial registration number UMIN000026053.

The importance of workers' well-being has been recognized in recent years. The assessment of well-being has been subjective, and few studies have sought potential biomarkers of well-being to date. This study examined the relationship between well-being and the LF/HF ratio, an index of heart rate variability that reflects sympathetic and parasympathetic nerve activity. Pulse waves were measured using photoplethysmography through a web camera attached to the computer used by each participant. The participants were asked to measure their pulse waves while working for 4 weeks, and well-being was assessed using self-reported measures such as the Satisfaction With Life Scale (SWLS), the Positive and Negative Affect Schedule (PANAS), and the Flourishing Scale (FS). Each of the well-being scores were split into two groups according to the median value, and the LF/HF ratio during work, as well as the number of times an LF/HF ratio threshold was either exceeded or subceeded, were compared between the high and low SWLS, positive emotion, negative emotion, and FS groups. Furthermore, to examine the effects of the LF/HF ratio and demographic characteristics on well-being, a multiple regression analysis was conducted. Data were obtained from 169 participants. The results showed that the low FS group had a higher mean LF/HF ratio during work than the high FS group. No significant differences were seen between the high and low SWLS groups, the high and low positive emotion groups, or the high and low negative emotion groups. The multiple regression analysis showed that the mean LF/HF ratio during work affected the FS and SWLS scores, and the number of times the mean LF/HF ratio exceeded +3 SD had an effect on the positive emotion. No effect of the LF/HF ratio on negative emotions was shown. The LF/HF ratio might be applicable as an objective measure of well-being.
