Schizophrenia is a disabling psychiatric illness associated with disruptions in cognition, emotion, and psychosocial and occupational functioning. Increasing evidence shows that psychosocial interventions for people with schizophrenia, as an adjunct to medications or usual psychiatric care, can reduce psychotic symptoms and relapse and improve patients' long-term outcomes such as recovery, remission, and illness progression. This critical review of the literature was conducted to identify the common approaches to psychosocial interventions for people with schizophrenia. Treatment planning and outcomes were also explored and discussed to better understand the effects of these interventions in terms of person-focused perspectives such as their perceived quality of life and satisfaction and their acceptability and adherence to treatments or services received. We searched major health care databases such as EMBASE, MEDLINE, and PsycLIT and identified relevant literature in English from these databases. Their reference lists were screened, and studies were selected if they met the criteria of using a randomized controlled trial or systematic review design, giving a clear description of the interventions used, and having a study sample of people primarily diagnosed with schizophrenia. Five main approaches to psychosocial intervention had been used for the treatment of schizophrenia: cognitive therapy (cognitive behavioral and cognitive remediation therapy), psychoeducation, family intervention, social skills training, and assertive community treatment. Most of these five approaches applied to people with schizophrenia have demonstrated satisfactory levels of short-to medium-term clinical efficacy in terms of symptom control or reduction, level of functioning, and/or relapse rate. However, the comparative effects between these five approaches have not been well studied; thus, we are not able to clearly understand the superiority of any of these interventions. With the exception of patient relapse, the longer-term (eg, .2 years) effects of these approaches on most psychosocial outcomes are not well-established among these patients. Despite the fact that patients' perspectives on treatment and care have been increasingly concerned, not many studies have evaluated the effect of interventions on this perspective, and where they did, the findings were inconclusive. To conclude, current approaches to psychosocial interventions for schizophrenia have their strengths and weaknesses, particularly indicating limited evidence on long-term effects. To improve the longer-term outcomes of people with schizophrenia, future treatment strategies should focus on risk identification, early intervention, person-focused therapy, partnership with family caregivers, and the integration of evidence-based psychosocial interventions into existing services.

Despite the drive towards evidence-based practice, the extent to which research evidence is being implemented in nursing practice is unclear, particularly in developing countries. This study was to assess the levels of perceived barriers to and facilitators of research utilization in practice among Chinese nurses and inter-relationships between these barriers and facilitators and their socio-demographic characteristics. A cross-sectional, descriptive survey was conducted in 2011 with 743 registered nurses randomly selected from four general hospitals in China. They completed the Barriers to Research Utilization and Facilitators of Research Utilization scales. Correlation tests were used to test the relationships between the nurses’ perceived barriers and facilitators, their demographic characteristics and research training and involvement. The Chinese nurses’ level of perceived barriers was moderate on average and lower than that in previous research. Among the 10 top-ranked items, six were from the subscale ‘Organizational Characteristics’. Their perceived barriers were correlated positively with age and post-registration experience and negatively with research training undertaken. Junior diplomatic nurses reported a significantly higher degree of barriers than those senior ones with postgraduate education. Higher and more diverse barriers to research utilization in practice are perceived by Chinese nurses than those in Western countries and they are associated with a few socio-demographic factors. Future research on these barriers/facilitators and their relationships with occupational and socio-cultural factors in Chinese and other Asian nurses is recommended.

BackgroundConstipation has a high prevalence rate (>30 %) in psychiatric patients with psychotropic drugs. Common pharmacological and non-pharmacological interventions for constipation might have longer-term negative and adverse effects that would outweigh their short-term efficacy in symptom reduction. This randomized controlled trial aims to investigate the effect of self-administered acupressure for the management of constipation, in hospitalized psychiatric patients.MethodsSeventy-eight patients were recruited in matched pairs in terms of gender, age and laxative use from five acute psychiatric wards in Hong Kong. Each of these matched pairs of patients was randomly assigned to either a self-administered acupressure (n = 39) or a sham group (n = 39), using computer-generated random numbers. After baseline measurement, the intervention and sham group received the same training in self-administered acupressure and supervised practice once per day for 10 days, except light pressure on non-acupoints was taught to the sham group. The acupoints chosen for acupressure included Zhongwan (RN12), right and left Tianshu (ST25), right and left Quchi (LI11). Participants’ symptoms and quality of life regarding constipation were measured at baseline and immediately and 2 weeks after completion of the interventions with constipation assessment scale and patient assessment of constipation quality of life questionnaire, respectively.ResultsAfter 2 weeks follow-up, participants who had received self-administered acupressure indicated significantly greater improvements in both symptom severity (P = 0.0003) and quality of life (P = 0.0004) when compared with the sham group.ConclusionThe psychiatric patients with constipation who practiced self-administered acupressure for 10 days improved their symptom severity and perceived quality of life immediately and 2 weeks after completion of the intervention in comparison with the sham group.Trial registration: The trial was registered with the ClinicalTrials.gov (Reg.
