Nonadherence to antipsychotic medication is a major cause of psychotic relapse and is strongly influenced by attitudes toward treatment. Although patient variables such as insight and symptoms that contribute toward attitudes have been identified, the contributions of relationship and service factors have not been adequately studied.
To determine relations between clinical and service variables and attitudes toward medication in people with a diagnosis of schizophrenia and schizoaffective disorder.
Consecutively admitted patients were approached to take part; 23 refused. Measures included symptoms, insight, drug adverse effects, self-reported adherence, attitudes toward treatment, perceived relationship with the prescriber, ward atmosphere, and admission experience. Data were analyzed by a proportional odds model and structural equation modeling to test predicted paths between experience of admission, relationship variables, attitudes toward treatment, and self-reported adherence to medication.
Twenty-eight inpatient wards at 8 hospitals in North Wales and the Northwest of England. Sites included hospitals with inner-city and rural catchment areas. Patients Two hundred twenty-eight patients meeting DSM-IV criteria for schizophrenia or schizoaffective disorder, assessed during acute admission.
Attitudes toward treatment and self-reported adherence to medication.
The data fit a model in which attitudes toward treatment were predicted by insight, relationship with staff (especially the physician-prescriber), and the patient's admission experience (maximum likelihood chi(2)(49) = 89.3, P<.001). A poor relationship with the prescriber, experience of coercion during admission, and low insight predicted a negative attitude toward treatment.
The quality of relationships with clinicians during acute admission appears to be an important determinant of patients' attitudes toward treatment and adherence to medication. Enhancing such relationships may yield important clinical benefits.

- "Finally, results of the regression analysis indicated that less than a quarter of the variance in attitudes could be attributed to the combined effect of all these variables. This suggests that attitude toward antipsychotics is a complex and multi-faceted construct with many potential determinants, some of which have still to be explored. "

Given the paucity of research in this area, this study attempted to assess attitudes toward antipsychotic medications and its correlates among patients with schizophrenia, either on first-generation antipsychotics (FGAs) or second-generation antipsychotics (SGAs) medications.
Materials and Methods:
Structured assessments of attitudes to antipsychotics, psychopathology, insight and side-effects were carried out in 120 patients with DSM-IV schizophrenia; 89 of these were on SGAs and 31 on FGAs.
Patients had predominantly positive attitudes toward antipsychotics. Severity of side-effects was the principal correlate of attitudes, explaining 19.5% of the variance, followed by greater insight (4.2% of the variance). Other factors such as younger age, male gender, employment, higher family income, urban residence and lower symptom-severity explained only a negligible proportion of the variance (0.2%) in attitudes. Patients on SGAs had more positive views of their medications than those on FGAs. They felt more normal on their medications, believed that their thoughts were clearer on medications, felt that good things about their medications outweighed the bad and believed that their medications helped them from falling ill again. In addition, they did not feel as tired and sluggish on their medications and did not believe that medications were unnatural or controlled their bodies.
Positive attitudes toward antipsychotics were common among patients with schizophrenia. Attitudes were principally determined by severity of side-effects and insight levels. Patients on SGAs had better attitudes, possibly because of less severe side-effects and greater insight among them. The importance of exploring patients’ attitudes toward their antipsychotics is highlighted by this study.

- "Following the HBM, medication adherence is likely to be influenced by subjective attitudes towards the medication, which in turn depend on cost-benefit considerations . As another limitation previous studies mostly included small subsets of possible predictors   rather than considering a comprehensive set of predictors. This makes it difficult to estimate the incremental amount of variance explained by each predictor. "

ABSTRACT: Although nonadherence to antipsychotic medication poses a threat to outcome of medical treatment, the processes preceding the intake behavior have not been investigated sufficiently. This study tests a process model of medication adherence derived from the Health Belief Model which is based on cost-benefit considerations. The model includes an extensive set of potential predictors for medication attitudes and uses these attitudes as a predictor for medication adherence. We conducted an online study of 84 participants with a self-reported psychotic disorder and performed a path analysis. More insight into the need for treatment, a higher attribution of the symptoms to a mental disorder, experience of less negative side effects, presence of biological causal beliefs, and less endorsement of psychological causal beliefs were significant predictors of more positive attitudes towards medication. The results largely supported the postulated process model. Mental health professionals should consider attitudes towards medication and the identified predictors when they address adherence problems with the patient in a shared and informed decision process.

- "Adherence to medication was based on patient responses to the Medication Adherence Questionnaire (MAQ), summed to obtain the 5-point Morisky score, ranging from 0 (poor adherence) to 4 (good adherence) (Morisky et al. 1986). This scale is widely used to assess adherence (Shalansky, 2004; Day et al. 2005). For the purpose of our new analyses, values 0–2 were interpreted as non-adherence, as per the classification used by the QUATRO team (Gray et al. 2006). "

ABSTRACT: Aims. For people with schizophrenia, non-adherence to antipsychotic medications may result in high use of health and other services. The objective of our research was to examine the economic consequences of non-adherence in patients with schizophrenia taking antipsychotic medication. Methods. Data were taken from QUATRO, a randomized controlled trial that drew a sample of adults with schizophrenia receiving psychiatric services in four European cities: Amsterdam, Leipzig, London and Verona. Trial inclusion criteria were a clinical diagnosis of schizophrenia, requiring on-going antipsychotic medication for at least 1-year following baseline assessment, and exhibiting evidence of clinical instability in the year prior to baseline. The patient-completed Medication Adherence Questionnaire (MAQ) was used to calculate the 5-point Morisky index of adherence. Generalized linear models (GLM) were developed to determine the effect of adherence on (i) health and social care and (ii) societal costs before and after treatment, taking into account other potential cost-influencing factors. Results. The effect of non-adherence on costs was mixed. For different groups of services, and according to treatment group assignment, non-adherence was both negatively and positively associated with costs. Conclusions. The impact of non-adherence on costs varies across the types of services used by individuals with schizophrenia.
