3-day intervention program for family members of hikikomori sufferers: A pilot randomized controlled trial.

Backgrounds: Hikikomori, pathological social withdrawal, is becoming a crucial mental health issue in Japan and worldwide. We have developed a 3-day family intervention program for hikikomori sufferers based on Mental Health First Aid (MHFA) and Community Reinforcement and Family Training (CRAFT). This study aims to confirm the effectiveness of the 3-day program by a randomized controlled trial. Methods: This study was registered on the UMIN Clinical Trials Registry (UMIN000037289). Fifteen parents were assigned to the treat as usual (TAU) group (TAU only; Age Mean, 65.6; SD, 7.8), and 14 to the Program group (program + TAU; Age Mean, 67.9; SD, 8.6). This study was discontinued due to the COVID-19 pandemic; the recruitment rate was 36.3% of our target sample size of 80. Results: Perceived skills improved temporally and stigma temporally worsened in the TAU group. Confidence decreased and attitude showed no change in both groups. Aggressive behaviors of hikikomori sufferers were significantly worsened in the Program group; however, no serious domestic violence was reported. In the TAU group, Avoidance and irregular life patterns were improved. Activity levels were worsened in both groups. Two participants (16.7%) in the Program group and one participant (7.7%) in the TAU group reported actual behavioral changes (e.g., utilizing support). Conclusion: We could not draw general conclusions on the effectiveness of the program due to the study discontinuation. Nevertheless, this study indicates the necessity for revision of the program to improve family members' confidence in engaging with hikikomori sufferers, with safer approaching by families.

Risk factors of hikikomori among office workers during the COVID-19 pandemic: A prospective online survey.

The global pandemic of COVID-19 has forced people to restrict their outings. In Japan, self-restraint behavior (SRB) has been requested by the government, and some of those decreasing their outings may shift to pathological social withdrawal; hikikomori. The purpose of this study was to examine the risk factors of hikikomori conducting an online prospective survey. An online survey was conducted in June 2020 and December 2020; (1) SRB-related indicators (degree of SRB, motivation for SRB, stigma and self-stigma toward COVID-19, anxiety and depressive feelings toward COVID-19) and (2) general mental health (hikikomori tendency, depressive symptoms, modern type depression (MTD) tendency, internet addiction) were collected. A cross-lagged effects model was performed to examine the association between these variables. Lack of emotional support and lack of socialization in June 2020 increased isolation in December 2020. Besides, MTD and hikikomori interacted with each other. Interestingly, although hikikomori tendency increased depressive tendencies, SRB itself did not have a significant path on any mental health-related variables. Poor interpersonal relationships, rather than SRB per se, are suggested to be a risk factor for increased isolation among office workers in the COVID-19 pandemic. Appropriate early interventions such as interpersonal or emotional support may prevent the transition to pathological hikikomori. The association between MTD and hikikomori seems to reveal the interesting possibility that MTD is a gateway to increased risk of hikikomori, and that hikikomori is a gateway to MTD as well. Future research is required to elucidate the relationship between hikikomori and MTD.

Association between Self-Restraint Behavior, Stigma and Depressive Tendency in Office Workers during the COVID-19 Pandemic in Japan—Self-Restraint Behavior and Depression during the COVID-19

Background: The COVID-19 pandemic has forced people to change their lifestyles, especially with respect to restrictions on going out. Forced quarantine (i.e., lockdown) and self-restraint behavior (SRB), including self-quarantine, are suggested to induce potential negative impacts on public mental health. SRB seems to be related to governmental policies, each individual’s social background and mental condition;however, no empirical studies have been conducted. Methods: 1053 participants (mainly office workers) from epidemic areas and non-epidemic areas in Japan voluntarily conducted an online survey in June 2020. We assessed COVID-19-related aspects such as the degree of SRB, motivation for SRB, stigma, anxiety and depressive feelings due to COVID-19 by original questionnaires) and general mental health status (social anxiety by MINI-SPIN, depressive tendency by PHQ-9, depression-related personality traits by TACS-22 and resilience by TRS). Results: Regional comparison showed significant differences in SRB and social anxiety. People in epidemic areas tend to refrain from going out. Conversely, people in non-epidemic areas tend to shun the public eye. Regardless of epidemic status, proactive SRB was associated with higher motivation for SRB, higher social anxiety, higher depressive tendency, stronger COVID-19-related psychological factors and lower resilience. Moreover, people with proactive SRB in non-epidemic areas had the highest depressive tendency. Discussion: The present cross-sectional survey among office workers in Japan showed that people with proactive SRB have stronger COVID-19-related anxiety and depressive feelings, regardless of where they live. Our key finding is that people with proactive SRB in non-epidemic areas have the highest depressive tendency. Based on the present finding, we herein propose the following hypothesis: Higher levels of depressive tendency may enhance proactive SRB, which may be partly associated with higher levels of stigma, anxiety and depressive feelings related to COVID-19. Limitations: The general tendencies to avoid danger and stigma were not evaluated. Conclusions: Depressive tendency is suggested to be associated with proactive SRB against COVID-19. Intervention for depressive tendency in non-clinical settings (e.g., workplaces) may help citizens understand the infectious situation appropriately and to behave effectively during the pandemic. Further investigations should be conducted to clarify the present findings.
