    Background:

    Currently, paradoxical findings exist regarding the level of functioning in individuals with Hikikomori (prolonged social withdrawal).

    Aims:

    This systematic review aimed to clarify the functioning, disability, and health of individuals with Hikikomori and their families in comparison to those without Hikikomori.

    Method:

    Relevant studies were searched from April 22 to 25, 2022, using MEDLINE, PsycINFO, Scopus, and two Japanese databases. Functions were categorized into ‘body functions”; “structure”; and “activity and participation’, which were further classified into subcategories.

    Results:

    Of the 8,181 studies screened, 24 studies with 1,769 individuals with Hikikomori were included. Twelve, three, and four indicators from six studies on depression and anxiety, three on addiction, and two on thought problem symptoms, respectively, were higher in the Hikikomori group than in the comparison group, with at least moderate effect sizes. Three indicators from three studies on interpersonal relationships were worse in the Hikikomori group, with at least moderate effect sizes. The meta-analyses showed that internalizing symptoms, externalizing symptoms, and thought disorders were significantly higher in the Hikikomori group than those in the comparison group with moderate-to-high effect sizes. Contrastingly, communication/interpersonal interactions were significantly lower in the Hikikomori group than those in the comparison group. No significant differences were observed in daily life/social life and the families’ communication/interpersonal interactions and relationship.

    Conclusions:

    The study limitations include a high risk of bias and heterogeneity. Overall, individuals with Hikikomori often have impaired mental and interpersonal interaction functions; thus, comorbidities of this condition should be carefully assessed. PROSPERO: CRD42022320592.

  • Successful remote treatment of a client with Hikikomori using internet-delivered cognitive therapy for social anxiety disorder: a case report Reviewed

    Hikikomori (prolonged social withdrawal) has been discussed as a hidden worldwide epidemic and a significant social and healthcare issue. Social anxiety disorder is the most common psychiatric disorder preceding the onset of Hikikomori. Although studies exist suggesting the effectiveness of family-support interventions, little is known about psychotherapeutic approaches for Hikikomori individuals. Here, we present a case of Hikikomori wherein an internet-delivered cognitive therapy for social anxiety disorder (iCT-SAD) worked effectively in improving the client’s social anxiety symptoms and social interaction behaviors. This case study demonstrates the principle that evidence-based psychological interventions focusing on social anxiety can be effective for clients with Hikikomori. Furthermore, the online mode of treatment delivery, along with a variety of relevant modules, may facilitate clients’ engagement with treatment at home. The findings suggest that iCT-SAD might be a promising option for Hikikomori clients who have social anxiety problems, within the recommended stepped-intervention approach.
