Activity limitations in the lower extremities in patients with osteoarthritis: the modifying effects of illness perceptions and mental health.

OBJECTIVES: Using the International Classification of Functioning, Disability and Health as framework, we evaluated modifying effects of illness perceptions and mental health on the association between impairments in body structures and functions due to osteoarthritis (OA) and limitation in activities in the lower extremities. METHODS: Self-reported limitation in activities was assessed by the Western Ontario and McMaster Universities OA index (WOMAC) function subscale in 316 patients with knee or hip pain or evidence of OA on knee or hip radiographs. Body structures and functions were evaluated during clinical and radiological assessments. Illness perceptions and mental health were assessed with the revised Illness Perception Questionnaire (IPQ-R) and the mental component summary score of the RAND 36-item Health Survey, respectively. For each patient an expected WOMAC function score was calculated, using an equation based on a multivariate model of the association of body structures and functions with limitation in activities. RESULTS: The median (interquartile) self-reported WOMAC function score was 22.2 (9.6-43.5). Ninety-one patients reported more and 120 patients reported less limitation in activities than expected. Patients with lumbar spine degeneration, physical or exercise therapy and high IPQ-R identity, consequences and chronic timeline scores had an increased risk to report more limitation in activities than the expected range. Low IPQ-R identity, consequences and emotional representation scores and better mental health were associated with reporting less limitation in activities than the expected range. CONCLUSION: Illness perceptions and mental health modify the association between self-reported limitation in activities and calculated limitation in activities based on impairments in body structures and functions due to OA.

Patients' illness perceptions and coping as predictors of functional status in psoriasis: a 1-year follow-up.

In a longitudinal study (two measurements with a 1-year interval), 69 patients with psoriasis completed the Illness Perception Questionnaire, the Medical Outcomes Study SF-20 Health Survey, and the Hospital Anxiety and Depression Scale. Data on coping (Utrecht Coping List) and severity of illness (body surface scores) were also collected. The results of regression analyses indicated that a strong illness identity was associated with more visits to the outpatient clinic, and worse outcome on physical health, social functioning, mental health, health perceptions and depression. Strong beliefs that the disease is controllable/curable and that the disease has disabling consequences were also related to more clinic visits and more negative perceived health, respectively. Patients who initially engaged in coping characterized by more expression of emotions, seeking more social support, seeking more distraction, and less passive coping were prescribed a lower number of different therapies, were less anxious, less depressed, and had a better physical health 1 year later. These results have implications for the management of patients with psoriasis, which reinforces current views on integrating psychosocial aspects into clinical care.

Physical and psychological correlates of functioning in patients with chronic obstructive pulmonary disease.

We studied the contribution of coping and illness perceptions to outcome in patients with chronic obstructive pulmonary disease (COPD). In a longitudinal study, 64 patients completed the Medical Outcomes Study Instrument and the Illness Perception Questionnaire. Data on coping and severity of illness (spirometry) were also collected. Regression analyses showed that first-time illness perceptions and coping significantly contributed to the prediction of social functioning, mental health, health perceptions, total functioning score, and prediction of visits to the outpatient clinic and prescribed medication 1 year later. These results have important implications for the medical management of patients with COPD.

Predicting functional status in patients with rheumatoid arthritis.

OBJECTIVE: To determine whether coping strategies and illness perceptions would be predictive of outcome in a longitudinal study of patients with rheumatoid arthritis (RA). METHODS: A group of 71 patients with RA was examined on 2 occasions, one year apart. Multiple regressions were used to examine which of the illness perceptions and coping strategies explained variance on the outcome variables: visits to the outpatient clinic, number of hospital admissions, Health Assessment Questionnaire, pain, tiredness, the Hospital Anxiety and Depression Scale. RESULTS: Belief in adverse consequences of the disease was associated with more visits to the outpatient clinic. more tiredness, and higher anxiety scores. Less perceived control and less expression of emotion were associated with more hospital admissions. High scores on coping involving fostering reassuring thoughts were associated with more functional disability. More passive coping was associated with more functional disability and higher anxiety scores. More perceived symptoms were associated with more pain, more tiredness, and more depression. More avoidant coping was associated with more tiredness. Belief that the illness will last a long time was associated with higher anxiety scores. CONCLUSION: Our longitudinal data show that, after statistically controlling for the potential effects of intervening medical variables, coping strategies and illness perceptions contribute to health outcome in patients with RA. Implications for patient management are discussed.

Illness perceptions, coping and functioning in patients with rheumatoid arthritis, chronic obstructive pulmonary disease and psoriasis.

The present cross-sectional study analyzed the extent to which illness perceptions and coping strategies (as measured by the Illness Perception Questionnaire and the Utrecht Coping List, respectively) are associated with levels of daily functioning, as indicated by the Medical Outcomes Study SF-20, and disease-specific measures in 244 adults: 84 with rheumatoid arthritis (RA); 80 with chronic obstructive lung disease (COPD); and 80 with psoriasis. The results of stepwise regression analyses indicated that a strong illness identity, passive coping, belief in a long illness duration, belief in more severe consequences, and an unfavorable score on medical variables were associated with worse outcome on disease-specific measures of functioning and on general role and social functioning. Coping by seeking social support and beliefs in controllability/curability of the disease were significantly related to better functioning. The implications of these findings for future interventions and research are discussed.
