Support-receiving networks and the isolation in schizophrenia: A preliminary study toward recovery-oriented occupational therapy.
Aiko Hoshino, Shinichi Nagata, Tatsumi Asakura and 1 others
Adults with schizophrenia in Japanese day-service centres reported fewer than one close contact on average.
Receiving help from others was the only factor linked to having any connections — loneliness, feeling valued, and helping others were not.
Key findings
1Participants reported an average of fewer than one close social contact, and most lived with family or in group homes yet still lacked close relationships and remained isolated.
2Receiving help from others was the only relationship factor significantly associated with network size; helping others, feeling valued (mattering), and loneliness were not.
3The mean loneliness score fell below the threshold generally considered to indicate high loneliness, even though the mean number of close contacts was less than one, suggesting self-reported loneliness may not capture the full extent of isolation in this group.

What it does not show
Only 31 participants from a single day-service centre in Japan; the authors note the high model fit may reflect overfitting and that generalisability is limited. Cross-sectional design: no causal claims can be made about receiving support causing larger networks. The General Mattering Scale was newly translated into Japanese and has not been psychometrically tested in a Japanese population. The Name Generator was limited to three alters; if most participants named three, the true network size may be underestimated. All participants attended day-service centres, so findings may not apply to people with schizophrenia in other settings (e.g., independent living, inpatient). Voluntary participation may have excluded those with the most extreme isolation who wished to avoid disclosing it. Findings are specific to the Japanese healthcare and cultural context (prolonged hospitalisation history, family cohabitation norms, stigma) and may not transfer to other countries.
Declared interests
The authors declared no potential conflicts of interest. Funding was provided by Tokai Pathways to Global Excellence (T-GEx), part of MEXT's Strategic Professional Development Program for Young Researchers — a government research-funding body, not a commercial sponsor.
The easy way to misread this
Do not read the strong model fit (R² = 0.84) as robust evidence that receiving support causes larger networks — with 31 participants and four predictors, the authors themselves flag the risk of overfitting, and the cross-sectional design means no causal direction can be established. The one significant association is a preliminary, correlational finding from a single Japanese day-service centre, not a treatment effect.
