Development of a questionnaire for evaluating supporters’ skills in Hikikomori support
Enhancing the skills of hikikomori supporters inherently contributes to improving the quality of support provided. However, a comprehensive skills assessment tool for these supporters has not yet been developed. This study aimed to develop a self-rated questionnaire, the Hikikomori Supporter’s Skills Checklist (HSSC). Based on a preliminary survey involving 43 supporters, the HSSC draft was revised. The revised version comprises 39 items addressi…
Functioning, disability, and health of individuals with Hikikomori (prolonged social withdrawal) and their families
Individuals with hikikomori and their families’ cognitive behavioral factors
Development of a 3‐Day Intervention Program for Family Members of Hikikomori Sufferers 1
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…
The suitability of outing frequency as a definition of hikikomori (prolonged social withdrawal)
These results indicate that outing frequency tends to be suitable as one of the conditions for hikikomori. However, they indicate that we should also focus on the quality of outings, that is, outings with or without interpersonal interaction, to evaluate hikikomori consistently with previous findings. Further research is needed to clarify the appropriate frequency of outings to define hikikomori and determine its severity
Day Intervention Program for Family Members of Hikikomori Sufferers
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
The Psychometric Properties of a Self- Report Scale on Assessing Social Interaction of People With Prolonged Social Withdrawal (Hikikomori)
Behavioral Repertoire of Families for Coping with Individuals with Hikikomori (Prolonged Social Withdrawal) in Japan1
This study aimed to examine the characteristics of families’ behavioral repertoires in hikikomori (prolonged social withdrawal) cases. We asked 243 parents of individuals with hikikomori ( hikikomori group) to complete the Family Behavioral Repertoire Scale for Coping With Hikikomori (FBS‐H), the Negative Evaluation of Hikikomori Scale, and a self‐efficacy measure of coping with problem behaviors of hikikomori in order to develop the FBS‐H and to…
Family Behavioral Repertoires and Family Interaction Influence the Adaptive Behaviors of Individuals With Hikikomori
Background: Family support is key in the initial stages of psychological support for individuals with hikikomori . However, it remains necessary to confirm the relationship between families' cognitive behavioral factors and the severity of hikikomori to understand ways of improving hikikomori. We examined the influences of family behavioral repertoires for coping with hikikomori and family interaction on the adaptive behaviors of individuals with…
Characteristics of Family Interaction of Individuals with Hikikomori (Prolonged Social Withdrawal) From the Viewpoint of Behavior Theory
The cognitive behavioral approach for families of individuals with hikikomori (IWH) places importance on assessing family interaction from a behavior theory. However, there is no gold standard method for the assessment of family interaction of IWH. Additionally, the characteristics of the family interactions of IWH have not been clarified. This study aims to (a) develop the Family Interaction Scale for Hikikomori (FIS‐H) using parent‐reported dat…
Assessing adaptive behaviors of individuals with hikikomori (prolonged social withdrawal)
It is important to appropriately assess the adaptive behaviors of individuals with hikikomori (IWH) using parent reports. However, currently, there is no gold standard in the assessment of adaptive behaviors of IWH. This study aimed to: (1) develop the Adaptive Behaviors Scale for Hikikomori (ABS-H); (2) examine the factor structure of the ABS-H; and (3) examine the reliability and validity of ABS-H. A factor analysis and item response theory (IR…
