All identified studies were observational, with sample sizes ranging from 51 to 214. Seven different psychosocial factors were investigated in the eight studies. Study analysis suggested that HbA<jats:sub>1c<\/jats:sub> may be associated with diabetes numeracy and quality of life. There were no indications of associations between HbA<jats:sub>1c<\/jats:sub> and fear of hypoglycaemia or self\u2010efficacy.
