The cognitive behavioral variables of a family that influence the improvement of prolonged social withdrawal (hikikomori) remain unclear. This study prospectively and experimentally examined the effects of family behavioral repertoire and family interaction on hikikomori recovery. The participants were selected from family associations and support centers in the Kanto region of Japan; the study was performed from May 2017 to March 2018. Overall, seven family members (four mothers and three fathers, aged 55–73) of hikikomori individuals (five males and two females, aged 20–47) participated in four 90-min individual sessions targeting cognitive behavioral variables (family behavioral repertoire, cognition of contingency, family interaction, and target behaviors); the intervention sessions were customized according to family characteristics, and participants were followed up at one, three, and six months after the intervention. Of these, three participants demonstrated improvements in up to two cognitive-behavioral variables after the intervention; furthermore, in all three cases, the social interactions of the hikikomori individuals increased later than the changes in their families. The time differences in these alterations suggest a causal relationship between family cognitive behavioral variables and recovery from hikikomori. However, Spearman’s correlation coefficients using the difference values from the pre-assessment were not significant for the hikikomori individuals’ social interactions and the families’ cognitive behavioral variables. These correlation analyses were preliminary because of the small sample size. Further studies with larger sample sizes and robust study designs are needed to confirm these findings.

Background: Although several surveys have suggested that socioeconomic factors function as background variables for the incidence of hikikomori (prolonged social withdrawal), no research has directly examined whether socioeconomic indicators increase the incidence of hikikomori. This study aimed to examine the relationship between socioeconomic factors and the incidence of hikikomori using data from eight cross-sectional studies conducted by our group between 2010 and 2019. Methods: We used socio-economic data from national surveys and collected the demographic data of members of a multi-branch Japanese association for family members of hikikomori patients for the period of 2010–2019. Results: The results of the partial correlation analysis showed that the incidence probability of hikikomori increased in tandem with unemployment rates and household income. Further, the associations were positively strong in the 2010–2015 research period; however, they were absent, weak, or medium in the 2016–2019 research period. Conclusions: The findings suggest that socioeconomic factors relate to the increase in hikikomori, and that these factors should be considered when identifying the individual or cultural factors that cause hikikomori.

Objective Cases of prolonged social withdrawal (hikikomori) have recently been reported in several countries. This study examined the impact of cognitive-behavioral and emotional factors on hikikomori behavior to identify intervention targets. Identifying such targets could facilitate the development of techniques to address hikikomori characteristics. Methods Two hundred Japanese individuals (mean age=38.73, SD=6.85) completed the Adaptive Behaviors Scale for Hikikomori and Stress Response Scale-18, along with the Japanese versions of the Self-Compassion Scale (Short Form), Acceptance and Action Ques-tionnaire-II, and Brief Coping Orientation to Problems Experienced Inventory. Participants were divided into two groups: individuals with no experience of social withdrawal, and those with experience of social withdrawal. Results Hierarchical multiple regression analysis showed that the use of instrumental support, behavioral disengagement stress coping skills, self-compassion, and psychological stress were associated with hikikomori behaviors. Furthermore, higher instrumental support levels, associated with a decrease in hikikomori behaviors, were found in the hikikomori group. Conclusion The use of instrumental support, behavioral disengagement stress coping skills, self-compassion, and psychological stress should be targeted in hikikomori prevention interventions. Moreover, encouragement for the use of instrumental support is needed for improving hikikomori.

Hikikomori (a severe form of social withdrawal) is a serious mental health issue. A family approach is the initial step to support hikikomori; thus effective family intervention programs are warranted. We recently developed a 5-day family intervention program (120 min weekly) based on Mental Health First Aid (MHFA) and Community Reinforcement and Family Training (CRAFT). In the present study, we modified the 5-day program to a 3-day program (180 min fortnightly), and examined the effectiveness of the 3-day program using a single-arm procedure. Data of 23 parents (four fathers and 19 mothers; age = 62.0 ± 9.1 years) were analyzed. Mental health conditions among participants themselves improved at the 4-month follow-up, but the confidence in hikikomori support declined and stigma toward mental health problems did not change. However, short-term improvements in perceived skills in approaching hikikomori sufferers were detected. Hikikomori sufferers’ actual behavioral changes, such as social participation or utilization of support, were also observed (six out of 20 hikikomori sufferers). Preliminary effectiveness was confirmed for the 3-day program. Further revision of the program and a validation study with controls are required.

This study assessed the social interaction behaviors of individuals with prolonged social withdrawal (HIKIKOMORI), subsequently developing a 26-item self-reported scale called the Adaptive Behaviors Scale for Hikikomori Self Report version (ABS-H-SR). The psychometric properties of the scale were confirmed using the item response theory. Confirmatory factor analysis (CFA) and item response theory (IRT) analysis were conducted using data from participants classified into three groups: the HIKIKOMORI group (n = 72), those who previously experienced it (previous group; n = 175), and the control group (n = 849). The reliability was assessed using the test-retest method and Cronbach’s alpha. The results suggest a reliable scale with acceptable criterion-related, convergent, and discriminant validity. This study suggests that the ABS-H-SR adequately assessed the social interaction behaviors of individuals with prolonged social withdrawal (HIKIKOMORI). Further research may clarify the extent to which the ABS-H-SR is sensitive to changes in the characteristics of prolonged social withdrawal (HIKIKOMORI).
