 Residential mobility increases motivation to expand social network: But why?. 
 Journal of Experimental Social Psychology, 49(2), 217-223. 
 doi:10.1016/j.jesp.2012.10.008

We conducted two studies to explore psychological consequences of a mobile lifestyle. In Study 1, we found that participants who were randomly assigned to think about a mobile lifestyle used more loneliness and sadness-related words and anticipated having fewer friends in the future than those who thought about a stable lifestyle (or a typical day as a control). In Study 2, we replicated this finding with a non-college sample. In addition, we found that those in the mobility condition reported being more motivated to expand their social network. Finally, the effect of mobility on the motivation to expand social networks was mediated by anticipated loneliness and sadness.

Is behavioral pro-sociality game-specific? Pro-social preference and expectations of pro-sociality.
Organizational Behavior and Human Decision Processes, 120(2), 260-271.

We observed the behaviors of the same people across five games—two prisoner’s dilemma games, a trust game (in which the subject took on the role of both trusterand trustee), a dictator game, and a faith game—any pair of which was separated by an interval of several months to reduce potential carry-over effects, and found strong consistency in behaviors among these games. We also found consistency between the expectations of other players’ behaviors and the player’s own behavior across games. We further found that the consistent behavioral pro-socialityobserved across different games was related to the general measures of pro-social value orientation and perceiving the game situations. These findings suggest that individual and cultural differences in game behaviors can reflect both the ways in which people perceive game situations and their general social preferences.

 Dissimilar effects of task‐relevant and interpersonal threat on independent–interdependent self‐construal in individuals with high self‐esteem. 
 Asian Journal of Social Psychology, 16(1), 50-59. 
 doi:10.1111/j.1467-839X.2012.01386.x

Previous research has indicated that individuals with high trait self-esteem (HSEs) become more independent and less interdependent after experiencing a task-relevant threat. However, these studies have not investigated other sources of ego threats, such as interpersonal threats. Therefore, the moderating effects of the degree of trait self-esteem on task-relevant and interpersonal ego threats were investigated in relation to independent, or interdependent self-construal. It was predicted that in HSEs, the level of task-relevant stress would be positively–negatively related to their independence–interdependence, whereas the level of interpersonal stress would be negatively–positively related to their independence–interdependence. In individuals with low trait self-esteem (LSEs), the two types of stresses and independent–interdependent self-construal may not have a significant relationship. We conducted a questionnaire survey with undergraduates.Correlational analysis of the results indicated that in HSEs, greater task-relevant stress was related to heightened independence, whereas greater interpersonal stress had the opposite effect, indicating lower independence and heightened interdependence. However, these stresses were not related to the self-construal of LSEs. These findings suggest that task-relevant and interpersonal threat could have differential effects on independent and interdependent self-construal for HSEs, but not in LSEs.

Process linking social support to mental health through a sense of coherence in Japanese university students.
Mental Health & Prevention.
doi: 10.1016/j.mhp.2016.05.00

This study aims to investigate the relationships among mental health, a “sense of coherence” (SOC), and social support in Japanese university students with a focus on gender differences. Participants (548 university students) completed General Health Questionnaire-12, of the SOC-13 scales, and of the social support scale. Structural equation modeling indicates indicate that improvement in social support may be effective in strengthening SOC as a precaution against the decline of mental health in university students. Additionally, it is suggested that enhancing support from friends in males and support from family members and special people in females is effective in strengthening SOC.

Predictors of depressive symptoms following the Great East Japan earthquake: A prospective study.
Social Science & Medicine.
doi: 10.1016/j.socscimed.2016.05.026

We sought to investigate prospectively the association between exposure to disaster (the 2011 East Japan Earthquake) and change in depressive symptoms among community-dwelling older adult survivors. We used two waves of data from the Japan Gerontological Evaluation Study (JAGES), an ongoing population-based, prospective cohort study in Japan. A unique feature of our study was the availability of information about mental health status pre-dating the disaster. Our sample comprised community-dwelling survivors aged 65 and older, who responded to surveys in 2010 (i.e. one year before the disaster) and in 2013 (n = 3464). We categorized disaster exposure according to three types of experiences: loss of family/friends, property damage, and disruption in access to medical service. Our main outcome was change in depressive symptoms, measured by the 15-item geriatric depression scale (GDS). Among the participants, 917 (26.5%) reported losing a family member to the disaster, while a further 537 (15.5%) reported losing a friend. More than half of the participants reported some damage to their homes. After adjusting for demographics and baseline mental health, people whose homes were completely destroyed had significantly elevated depressive symptom scores three years later (+1.22 points, 95%CI: 0.80, 1.64, p < 0.0001). Disruption of psychiatric care was also associated with change in GDS scores (+2.51 points, 95%CI: 1.28, 3.74, p < 0.0001). By contrast, loss of family/friends was no longer associated with GDS after 3 years; +0.18 points (95%CI: −0.018, 0.37, p = 0.08) for loss of family, and −0.045 points (95%CI: −0.28, 0.19, p = 0.71) for loss of friends. Three years after the disaster, survivors of the 2011 earthquake and tsunami appeared to have recovered from loss of loved ones. By contrast, property loss and disruption of psychiatry care were associated with persistent adverse impact on mental health.
