“…37 Our study showed negative associations between age, and personal control and treatment control indicating that as the patient ages, he/she may have negative beliefs about personal abilities to control his/her RA and about the ability of treatment to control RA. It may be expected that longer disease duration leading to erosions and living with affected joints for many years may lead to negative beliefs about RA.…”

Objectives: This study aims to assess the factor structure of the Turkish Revised Illness Perception Questionnaire (IPQ-R) in patients with rheumatoid arthritis (RA) and the relationship of illness perceptions with disease activity and psychological well-being. Materials and methods: One hundred and fifty RA patients (8 males, 142 females; mean age 51.1±12.7 years; range 21 to 81 years) were included in the study. Confirmatory factor analysis was used to test the factor structure of the IPQ-R. Pain was assessed by visual analog scale, disease activity by Disease Activity Score 28, depression by Beck Depression Inventory, global life satisfaction by the Satisfaction with Life Scale, and illness perception by the IPQ-R. Results: Three items (items 12, 18, 19) were deleted because of poor factor loadings. The modified 35-item model showed good reliability and discriminant validity. Beck Depression Inventory scores were correlated with identity, consequences, and emotional representations subscales positively (p<0.001); and with illness coherence subscale negatively (p<0.05). There were positive correlations between Satisfaction with Life Scale scores, and treatment control and illness coherence subscales (p<0.05). Satisfaction with Life Scale scores were negatively correlated with identity, emotional representation, and timeline acute/chronic subscales (p<0.05), and consequences subscale (p<0.001). Disease Activity Score 28 was not correlated with IPQ-R domains (p>0.05). Conclusion:The Turkish IPQ-R appears to be a useful clinical assessment tool to evaluate RA-related illness perceptions. RA healthcare should include psychological intervention to strengthen patients' beliefs about their RA regardless of disease activity.

“…The negative associations between medication adherence and the identity and consequences subscales are unexpected as the Common Sense Model and Health Belief Model both suggest if an individual believes their illness can have severe consequences then it would be expected that the take actions to reduce this threat, such as adhering to their medicine. 17,158,165 A prospective study is needed to confirm the direction of the relationship between identity and consequence illness perception subscales with medication adherence in type 2 diabetes. A possible explanation is that cross-sectional studies are picking up the result of adherence.…”

“…180,[184][185][186] Other findings suggest there is not a strong relationship between the understanding subscale and adherence. 64,158,167,169 The cause subscale is usually analysed as a categorical variable. The perceived cause of illness is generally categorised into different factors (e.g.…”

“…A previous systematic review found no correlation between perceived understanding and medication adherence, but the review did not have any studies conducted in asthma. 158 Individuals who can make sense of their asthma, its symptoms and treatment, and therefore have a better overall understanding of their asthma are more likely to adhere to their medication. This perception is said to represent a 'metacognition' where the patient evaluates their understanding of their illness and is thought to be important for long-term adjustment and responding to symptoms.…”

In individuals with asthma, non-adherence to inhaled corticosteroids contributes to increased exacerbations, healthcare utilisation and mortality. Understanding the beliefs an individual holds about their medicines, illness and about the controllability of their health provides a promising way to better understand non-adherence in individuals with chronic conditions. Research to date has focussed on bivariate relationships between a specific set of beliefs and medication adherence. This approach simplifies the complex, multifaceted nature of medication adherence. I suggest that investigating how different beliefs associate with medication adherence in a multivariable model may improve understanding of adherence decisions.The aim of the thesis is to investigate the relationship between beliefs about medicines, illness perceptions and locus of control beliefs with self-reported medication adherence in individuals with asthma.The first part of the thesis was to identify whether beliefs about medicines, elicited through the Beliefs about Medicines Questionnaire (BMQ), were correlated to medication adherence on a population level. The BMQ consists of two scales that seek to elicit an individual's beliefs in the necessity and concerns of taking medication. Necessity beliefs reflect medicines being protective of current and future health and concern beliefs reflect beliefs about the negative effects of medicines. Beliefs about medicines are thought to play a key role in medication-taking, but inconsistent results across different conditions and different measures of adherence makes it difficult to conclude the size of the effect at a population level. A meta-analysis was conducted to identify whether beliefs in the necessity and concerns of medicines, were significantly correlated with medication adherence across different conditions. An electronic search was conducted for manuscripts comparing scores from the BMQ to measures of medication adherence. Studies were pooled using the random-effects model to produce a mean effect size correlation. Studies were stratified for condition, adherence measure, power and study design. Ninety-four papers were included and the overall effect size correlation was 0.17 for necessity and -0.18 for concerns (p<0.0001). Necessity and concerns beliefs were correlated with medication adherence on a population level and across the majority of included conditions. The effect sizes were small with a magnitude comparable to other predictors of adherence. Exploring the role of beliefs outside the Beliefs about Medicines Framework may improve prediction and understanding of medication adherence.A cross-sectional study was conducted to explore the relationship between measures of health beliefs and medication adherence in individuals with asthma. A total of 198 participants using a preventative asthma inhaler for three or more months were recruited from two community pharmacies and via iii online advertisement. Each participant completed a survey of validated questionnaires consisting of:...

Psychotherapists can improve their patients' outcomes during and after therapy by improving patients' self‐management. Patients who do not effectively manage their mental illness generally have worse outcomes. Leventhal's Common‐Sense Model of Self‐Regulation theorizes that patients' perceptions of their illness (illness representations) guide their self‐management, influencing health outcomes. The present study quantified the relations between illness representations, self‐management and outcomes for mental illnesses. We conducted a meta‐analysis and included articles if they reported (1) on adults with mental illnesses and (2) the correlation between mental illness representations and mental illness outcomes. Twenty‐five articles were included which represented 28 independent samples. The pattern of correlations among illness representations (identity, consequences, timeline, control, coherence and emotional representations), self‐management strategies (attendance, engagement and adherence to treatment) and mental illness outcomes (symptom severity and quality of life) was consistent with analyses from previous studies of mental and physical illnesses. The results found threat‐related illness representations mostly had a large relationship with worse mental illness outcomes and self‐management. Protective illness representations had a small‐to‐large relationship with better mental illness outcomes and self‐management. The results suggest patients' perceptions of their mental illness may be a critical indicator of their mental illness outcomes, including symptom severity and quality of life. This theory‐driven meta‐analysis supports calls for the inclusion of illness representations in psychotherapy for mental illness.
