BackgroundNeurocognitive dysfunction is a critical target symptom of schizophrenia treatment. A positive correlation between physical activity level and neurocognitive function has been reported in healthy individuals, but it is unclear whether such a correlation exists in patients with schizophrenia and whether the relationship is different according to inpatients or outpatients. This study aimed to examine the differences in the correlations between physical activity and multiple neurocognitive domains in inpatients and outpatients with schizophrenia and obtain suggestions for further study to facilitate this field.MethodsTwenty-nine patients with schizophrenia were examined (16 inpatients and 13 outpatients, 56.0 ± 11.4 years of age). Current symptoms were assessed using the Positive and Negative Symptom Scale and neurocognitive functions using Cognitrax, which yields a composite neurocognitive index (NCI) and 11 domain scores. After testing, participants wore an HJA-750C accelerometer for one week to measure physical activity levels and durations. Partial correlation analyses were performed between exercise and cognitive parameters.ResultsIn the outpatient group, higher physical activity was associated with faster Motor and Psychomotor Speeds in outpatients. However, higher physical activity was associated with lower overall NCI, Attention score, and Memory scores in inpatients.ConclusionAlthough higher physical activity was associated with better neurocognitive functions of outpatients, in inpatients with non-remitted schizophrenia, higher physical activity was associated with worsening of several cognitive domains. In a future study examining the relationship between physical activity and neurocognitive function for facilitating this research field, separation between inpatients and outpatients are needed because the relationship is different between inpatients and outpatients.Electronic supplementary materialThe online version of this article (doi:10.1186/s12888-016-1176-z) contains supplementary material, which is available to authorized users.

Purpose: This study examined the association of self-focus and self-compassion with nursing competency.Design and Methods: Data of 433 psychiatric nurses comprising demographics, other-consciousness, self-compassion, self-focus, and nursing competency were analyzed using the Other-Consciousness Scale (OCS), Self-Compassion Scale (SCS), Japanese version of the Rumination-Reflection Questionnaire (RRQ), and Oriented Problem Solving Behavior (OPSN).Findings: Higher internal aspect and lower fantastic aspect in OCS, higher reflection in RRQ, and lower SCS negative subscales predicted a higher OPSN score. The account rate of variance was 12.5%.

Nursing education should facilitate other-consciousness in general nurses, but self-focus in psychiatric nurses.

To facilitate discharge for nonremitted inpatients, nursing could focus on processing speed, e.g., arranging the environment such that patients do not need quick responses.
