I don't disagree at all.

I am merely commenting on your takeaway that this somehow means that some cultures see schizophrenia as "friendly", which does absolutely does not follow from the fact that the "mostly, the voices are good".

I would also think that this is likely due to cultural differences and in many cases probably adds to the problem.

From the full Article:

"People suffering from psychotic illness continue to hold multi-explanatory models. The cultural, religious and social explanatory models are predominant in non-western cultures."

"Limited evidence suggests that traditional belief models affect [duration of untreated psychosis], and explanatory models based on spiritual and social causes of illness may result in delayed presentations for professional help."
