Metacognitions, emotion and disordered eating in women

Objective: This study investigates the relationships between metacognitions, emotions and disordered eating in women with or without an eating disorder, as well as differences between these groups. Method: 326 participants were included in the study and completed the following questionnaires: Hospital Anxiety and Depression Scale (HADS), Meta-Cognitions Questionnaire 30 (MCQ-30) and the Eating Disorder Examination Self-Report Questionnaire (EDE-Q). Results: Women with an eating disorder expressed more metacognitive concerns than women without a significant disordered eating pathology. Regression analysis showed that the majority of eating disorder symptoms were predicted by anxiety and depression for both groups, but the need to control thoughts was the only metacognition which stood out as an independent predictor of disordered eating. Discussion: Implications of these findings as well as the limitations of this study are discussed

The efficacy of psychologically based interventions to improve anxiety, depression and quality of life in COPD: a systematic review and meta-analysis

This article comprises a systematic review and meta-analysis looking at the efficacy of psychological intervention in improving anxiety, depression and quality of life in respiratory disease.Objective: To systematically evaluate the efficacy of psychologically based interventions for addressing psychological outcomes in patients with chronic obstructive pulmonary disease (COPD). Methods: Electronic databases, key journals and reference lists of included studies were scrutinised for inclusion; in addition authors were contacted for potential unpublished research. Nine studies were identified for inclusion. Data was extracted by two reviewers independently using a standardised extraction sheet and a series of meta-analyses completed for measures of anxiety, depression and quality of life. Results: Eight studies evaluated a cognitive behavioural- or psychotherapeutically based intervention and one study evaluated taped progressive muscle relaxation. The studies revealed some evidence for the interventions’ impact on anxiety, but, taken together interventions had limited effectiveness. The meta-analyses that were conducted revealed a small effect for anxiety only. Conclusion: The results are discussed considering the limitations of the research and previous work in this area. A systematic evaluation of psychological interventions on psychological co-morbidity in patients with COPD is recommended. Practice implications: There is some evidence that psychological interventions impact anxiety and this should be explored further and more interventions should target quality of life

Facilitators and barriers to physical activity following pulmonary rehabilitation in COPD: a systematic review of qualitative studies

Pulmonary rehabilitation has short-term benefits on dyspnea, exercise capacity and quality of life in COPD, but evidence suggests these do not always translate to increased daily physical activity on a patient level. This is attributed to a limited understanding of the determinants of physical activity maintenance following pulmonary rehabilitation. This systematic review of qualitative research was conducted to understand COPD patients’ perceived facilitators and barriers to physical activity following pulmonary rehabilitation. Electronic databases of published data, non-published data, and trial registers were searched to identify qualitative studies (interviews, focus groups) reporting the facilitators and barriers to physical activity following pulmonary rehabilitation for people with COPD. Thematic synthesis of qualitative data was adopted involving line-by-line coding of the findings of the included studies, development of descriptive themes, and generation of analytical themes. Fourteen studies including 167 COPD patients met the inclusion criteria. Seven sub-themes were identified as influential to physical activity following pulmonary rehabilitation. These included: intentions, self-efficacy, feedback of capabilities and improvements, relationship with health care professionals, peer interaction, opportunities following pulmonary rehabilitation and routine. These encapsulated the facilitators and barriers to physical activity following pulmonary rehabilitation and were identified as sub-themes within the three analytical themes, which were beliefs, social support, and the environment. The findings highlight the challenge of promoting physical activity following pulmonary rehabilitation in COPD and provide complementary evidence to aid evaluations of interventions already attempted in this area, but also adds insight into future development of interventions targeting physical activity maintenance in COPD

Self-efficacy instruments for patients with chronic diseases suffer from methodological limitations - a systematic review

BACKGROUND: Measurement of self-efficacy requires carefully developed and validated instruments. It is currently unclear whether available self-efficacy instruments for chronic diseases fulfill these requirements. Our aim was to systematically identify all existing self-efficacy scales for five major chronic diseases and to assess their development and validation process. METHODS: We conducted a systematic literature search in electronic databases (MEDLINE, PSYCHINFO, and EMBASE) to identify studies describing the development and/or validation process of self-efficacy instruments for the five chronic diseases diabetes, chronic obstructive pulmonary disease (COPD), asthma, arthritis, and heart failure. Two members of the review team independently selected articles meeting inclusion criteria. The self-efficacy instruments were evaluated in terms of their development (aim of instrument, a priori considerations, identification of items, selection of items, development of domains, answer options) and validation (test-retest reliability, internal consistency reliability, validity, responsiveness) process. RESULTS: Of 584 potentially eligible papers we included 25 (13 for diabetes, 5 for asthma, 4 for arthritis, 3 for COPD, 0 for heart failure) which covered 26 different self-efficacy instrument versions. For 8 instruments (30.8%), the authors described the aim before the scales were developed whereas for the other instruments the aim was unclear. In one study (3.8%) a priori considerations were specified. In none of the studies a systematic literature search was carried out to identify items. The item selection process was often not clearly described (38.5%). Test-retest reliability was assessed for 9 instruments (34.6%), validity using a correlational approach for 18 (69.2%), and responsiveness to change for 3 (11.5%) instruments. CONCLUSION: The development and validation process of the majority of the self-efficacy instruments had major limitations. The aim of the instruments was often not specified and for most instruments, not all measurement properties that are important to support the specific aim of the instrument (for example responsiveness for evaluative instruments) were assessed. Researchers who develop and validate self-efficacy instruments should adhere more closely to important methodological concepts for development and validation of patient-reported outcomes and report their methods more transparently. We propose a systematic five step approach for the development and validation of self-efficacy instruments

Evidence for cognitive–behavioral strategies improving dyspnea and related distress in COPD

BACKGROUND: Dyspnea is a complex, prevalent, and distressing symptom of chronic obstructive pulmonary disease (COPD) associated with decreased quality of life, significant disability, and increased mortality. It is a major reason for referral to pulmonary rehabilitation. METHODS: We reviewed 23 COPD studies to examine the evidence for the effectiveness of cognitive-behavioral strategies for relieving dyspnea in COPD. RESULTS: Preliminary evidence from randomized controlled trials exists to support cognitive- behavioral strategies, used with or without exercise, for relieving sensory and affective components of dyspnea in COPD. Small to moderate treatment effects for relieving dyspnea were noted for psychotherapy (effect size [ES] = 0.08-0.25 for intensity; 0.26-0.65 for mastery) and distractive auditory stimuli (ES = 0.08-0.33 for intensity; 0.09 to -0.61 for functional burden). Small to large dyspnea improvements resulted from yoga (ES = 0.2-1.21 for intensity; 0.67 for distress; 0.07 for mastery; and -8.37 for functional burden); dyspnea self-management education with exercise (ES = -0.14 to -1.15 for intensity; -0.62 to -0.69 for distress; 1.04 for mastery; 0.14-0.35 for self-efficacy); and slow-breathing exercises (ES = -0.34 to -0.83 for intensity; -0.61 to -0.80 for distress; and 0.62 for self-efficacy). Cognitive-behavioral interventions may relieve dyspnea in COPD by (1) decreasing sympathetic nerve activity, dynamic hyperinflation, and comorbid anxiety, and (2) promoting arterial oxygen saturation, myelinated vagus nerve activity, a greater exercise training effect, and neuroplasticity. CONCLUSION: While evidence is increasing, additional randomized controlled trials are needed to evaluate the effectiveness of psychosocial and self-management interventions in relieving dyspnea, in order to make them more available to patients and to endorse them in official COPD, dyspnea, and pulmonary rehabilitation practice guidelines. By relieving dyspnea and related anxiety, such interventions may promote adherence to exercise programs and adaptive lifestyle change

Patterns, predictors, and associated benefits of driving a modified vehicle after spinal cord injury: Findings from the national spinal cord injury model systems

Objectives To investigate the patterns, predictors, and benefits associated with driving a modified vehicle for people with spinal cord injuries (SCIs). Design Cross-sectional retrospective survey design. Settings Sixteen Model SCI Systems (MSCISs) throughout the United States. Participants People (N=3726) post-SCI from the National MSCIS Database. Interventions Not applicable. Main Outcome Measures Driving, employment, and community reintegration post-SCI. Results The study found that 36.5% of the sample drove a modified vehicle after SCI. Significant predictors of driving a modified vehicle post-SCI included married at injury, younger age at injury, associate's degree or higher before injury, paraplegia, a longer time since the injury, non-Hispanic race, white race, male sex, and using a wheelchair for more than 40 hours a week after the injury (accounting for 37% of the variance). Higher activity of daily living independence (in total motor function) at hospital discharge also increased the odds of driving. Driving increased the odds of being employed at follow-up by almost 2 times compared with not driving postinjury (odds ratio, 1.85). Drivers tended to have higher community reintegration scores, especially for community mobility and total community reintegration. Driving was also associated with small health-related quality-of-life gains, including less depression and pain interference and better life satisfaction, general health status, and transportation availability scores. Conclusions The associated benefits of driving and the relatively low percentage of drivers post-SCI in the sample provide evidence for the need to increase rehabilitation and assistive technology services and resources in the United States devoted to facilitating driving after SCI. © 2011 American Congress of Rehabilitation Medicine
