BackgroundNearly half of patients with schizophrenia do not adhere to the long-term medical treatment needed to manage their disease. Programs to promote medication adherence include promotion of motivation as a critical element to influence task performance.PurposeThis study investigated the mediating effect of motivation for medication use on disease management and medication adherence in schizophrenia.MethodsThis cross-sectional, descriptive correlational study enrolled a convenience sample of 373 community-dwelling patients with schizophrenia in the northern and central regions of Taiwan. Data were collected with questionnaires and a series of validated assessment tools. Hierarchical regression was used to analyze the mediating effect of motivation for medication use on disease management and medication adherence.ResultsThe medication adherence rate of the patients was 47.2%. The mediating effect of motivation for medication use on therapeutic alliance and medication adherence was 50%, whereas that on insight and medication adherence was 41% and that on medical social support and medication adherence was 72%.ConclusionDeveloping a medication motivation care model may be more effective than promoting therapeutic alliance, insight, or medical social support for promoting medication adherence. It also had greater impact on preventing relapses of community-dwelling patients with schizophrenia.

Background Increased medication adherence improves patient outcomes and lowers the overall cost of care by preventing disease relapse and hospital readmission. Several systematic reviews have identified that insight, therapeutic alliance, and attitude towards medication affect medication adherence in patients with schizophrenia; however, no study has examined all the aforementioned variables together nor has discussed the chains of these mediators. Purpose To examine the insight–medication adherence relationship among community-dwelling schizophrenia patients through a serial multiple mediation model of therapeutic alliance and medication attitude. Patients and Methods This study with a cross-sectional correlational design included a convenience sample of community-dwelling schizophrenia patients from Taiwan (n = 229). From January 2017 to January 2018, data were collected by trained nurses using questionnaires. The PROCESS tool was used to analyse fine-grained chains. Results In serial multiple mediation, the indirect effect of insight on medication adherence through therapeutic alliance and, subsequently, alteration of medication attitude was significant. However, the direct effect changed from significant to non-significant, indicating a complete mediating effect. Conclusion In community-dwelling schizophrenia patients, the effects of therapeutic alliance and medication attitude on medication adherence are greater than that of insight. We recommend revising the strategy of community home visits by different psychiatrists or nurses in alternating shifts. Therapeutic alliance is the first step required to promote medication adherence. Based on this alliance, altering the patients’ medication attitude may be more effective in improving medication adherence than merely enhancing insight.

Background Functional degradation among community-dwelling patients with schizophrenia can negatively influence their recovery. Given the importance of patient empowerment during recovery, this study examined the mediating effect of empowerment on the relationship between global function and personal recovery among community-dwelling patients with schizophrenia. Methods This cross-sectional study recruited community-dwelling patients with schizophrenia from northern and central Taiwan. Questionnaires with verified reliability and validity were provided and collected on site by trained nurses. Global function, empowerment, and personal recovery were measured using the Global Assessment of Functioning (developed by the American Psychiatric Association), Empowerment Scale, and Questionnaire on the Process of Recovery, respectively. The causal steps approach proposed by Baron and Kenny and the Sobel test were utilized to verify the mediation effect. The causal steps approach tested the four following pathways (regression coefficients): global function on empowerment (Path a), global function and empowerment as predictors of personal recovery (Path b), global function on personal recovery (Path c), and global function and empowerment on personal recovery (Path c’). Results A total of 373 participants completed the survey. After controlling for factors associated with recovery, Paths a (β = .24, p < .001), b (β = .68, p < .001), and c (β = .19, p < .001) were found to be significant; however, Path c’ was not significant (β = .03, p = .452). Empowerment was determined to exert “full mediation” over the effects of global function on personal recovery, and the Sobel test indicating significant mediation (Z = 3.61, p < .001). Conclusions Empowerment fully mediates the association between global function and personal recovery. This study suggested that offering empowerment-oriented care services may be more effective than global function improvement in recovery among these patients.

Background Adherence therapy (AT) is an intervention for improving medication adherence of people with schizophrenia spectrum disorders, but no systematic reviews have yet summarized the effectiveness and minimum treatment duration of AT. We here aimed to systematically examine the effectiveness of AT in improving outcomes versus treatment as usual (TAU) and its minimum effective duration for people diagnosed with schizophrenia spectrum disorders. Patients and Methods Eligible randomized controlled trials were identified from four databases (Web of Science, PubMed, CINAHL and Cochrane Library) for the period 1 January 2006 to 1 January 2023. Of 1087 retrieved candidate studies, five studies with a total of 726 participants met the inclusion criteria. The search terms consisted of adherence therapy, compliance therapy, schizophrenia, schizoaffective disorder, schizophrenic disorder, medication adherence, and medication compliance (combined with OR and AND). Two investigators independently selected studies, extracted data, and conducted bias risk assessments. Random-effects models were used to analyze the pooled data. Results Meta-analysis of the five selected studies showed that AT had a significantly greater positive effects than TAU on psychiatric symptoms, but no significant effects on adherence behaviors and attitudes. Conclusion The AT had limited effects in terms of improving the attitudes and behaviors of people with schizophrenia spectrum disorders with respect to medication adherence, but did improve patients’ psychiatric symptoms. The therapy should be performed by trained staff for maximum benefit, and the recommended duration of the intervention is 12 hours.

Background: Functional degradation among community-dwelling patients with schizophrenia can negatively influence their recovery. Given the importance of patient empowerment during recovery, the current study aimed to examine the mediating effects of patient empowerment on the relationship between global function and recovery among such patients.Methods: This cross-sectional study recruited community-dwelling patients with schizophrenia from northern and central Taiwan. Questionnaires with verified reliability and validity were provided and collected on site by trained nurses. The causal steps approach proposed by Baron and Kenny and the Sobel test were utilized to verify the mediation effect.Results: A total of 373 participants completed the survey. After controlling for factors associated with recovery, empowerment was determined to exert “full mediation” over the effects of global function on patient recovery, with the mediation effect reaching 85.9% and the Sobel test indicating significant mediation.Conclusions: Although improving the global function of community-dwelling patients with schizophrenia could likely encourage recovery, the present study suggested that offering empowerment-oriented care services may be more effective than global function improvement on recovery among these patients.
