Patient-reported outcome measurement has become accepted as an important component of comprehensive outcomes research. Researchers wishing to use a patient-reported measure must either develop their own questionnaire (called an instrument in the research literature) or choose from the myriad of instruments previously reported. This article summarizes how previously developed instruments are best assessed using a systematic process and we propose a system of quality assessment so that clinicians and researchers can determine whether there exists an appropriately developed and validated instrument that matches their particular needs. These quality assessment criteria may also be useful to guide new instrument development and refinement. We welcome debate over the appropriateness of these criteria as this will lead to the evolution of better quality assessment criteria and in turn better assessment of patient-reported outcomes.

Three studies are reported, which examined individual differences in deductive reasoning as a function of intellectual ability and thinking style. Intellectual ability was a good predictor of logical performance on syllogisms, especially where there was a conflict between logic and believability. However, in the first two experiments there was no link between ability and performance on indicative selection tasks, in sharp contrast to previous research. This correlation did, however, return in the final study. Our data are consistent with the claim that the correlation with logical accuracy on abstract selection tasks is found primarily with participants of relatively high ability. At lower levels, pragmatically cued responses are given but those of slightly higher ability divorce the rule from the scenario and respond consistently (though incorrectly) across problems. Self-report questionnaires were generally poor predictors of performance, but a measure of the ability to generate alternative representations proved an excellent predictor. These results are consistent with a mental models approach to reasoning and also have implications for the debate about human rationality.

Introduction and aim. In a randomised trial investigating the effects of regular

Sexual functioning is an important element of quality of life. Many women experience sexual problems as a result of a breast cancer diagnosis and its treatment. Little is known about the availability and the effectiveness of interventions for sexual problems in this patient population. Six electronic databases were searched using Medical Subject Headings and keywords. Additional hand searching of the references of relevant papers was also conducted. The searches were conducted between October 2010 and January 2011. Papers were included if they evaluated interventions for sexual problems caused as a result of breast cancer or its treatment. Studies were only included if sexual functioning was reported using a patient-reported outcome questionnaire. Studies were excluded if sexual functioning was measured but improving sexual problems was not one of the main aims of the intervention. 3514 papers were identified in the initial search. 21 papers were selected for inclusion. Studies were of mixed methodological quality; 15 randomised trials were identified, many included small sample sizes and the use of non-validated questionnaires. Three main types of interventions were identified: Exercise (2), medical (2) and psycho-educational (17). The psycho-educational interventions included skills-based training such as problem-solving and communication skills, counselling, hypnosis, education and specific sex-therapies. Interventions were delivered to individual patients, patients and their partners (couple-based) and groups of patients. The widespread methodological variability hinders the development of a coherent picture about which interventions work for whom. Tentative findings suggest the most effective interventions are couple-based psycho-educational interventions that include an element of sexual therapy. More methodologically strong research is needed before any intervention can be recommended for clinical practice. Improved screening and classification of sexual problems will ensure interventions can be more effectively targeted to suit individual patient needs.

Evaluation of the system in a randomised controlled trial in breast, gynaecological and colorectal cancer patients undergoing systemic therapy is currently underway. To adapt eRAPID for different treatment groups, pilot studies are being undertaken with patients receiving pelvic radiotherapy and upper gastrointestinal surgery. ISRCTN88520246.

Objective Chronic cancer is poorly defined and strategies for supporting patients during this disease phase are lacking. This research defines chronic cancer, explores patient experiences, and reviews patients' support needs against those described in the 2007 Department of Health Generic Choice Model for Long-term Conditions (DoH-GCM).Design Semi-structured interviews were audio-recorded, transcribed, and data explored for emergent themes. A-priori themes from the DoH-GCM were applied: clinical support; self-care and self-management; supporting independence; psychological support; and social and economic factors.Results 56 patients >12 months post-diagnosis of advanced cancer were recruited from five clinics at a Yorkshire cancer centre: breast (n=11); renal (n=11); colorectal/gastrointestinal (n=12); gynaecological (n=12); prostate (n=10). Most patients aspired to living normal lives. Challenges included frequent and lengthy hospital appointments, long-term symptom control, and uncertainty. Only renal and prostate patients reported routine access to specialist nursing. Uptake of support services was varied and there was generally poor understanding of support pathways for non-medical problems and issues occurring when patients were not receiving active treatment. There was variation in coping strategies and ability of patients to attain a positive outlook on life.Conclusion For patients to do well in this cancer phase requires good self-management of symptoms plus taking an active role in accessing appropriate services as needed. Care planning at the point of transition to the chronic phase of cancer should focus on evaluating patients' needs, clarifying support pathways, increasing the profile and involvement of community services and organisations, and supporting patients and families develop effective self-management skills.

Low prevalence of discussion of psychosocial issues cannot be accounted for by patient or clinician communication preferences. If clinicians rely on patients to initiate discussion of psychosocial issues, patients' problems may go unaddressed.

Older adults have been shown to trip on obstacles despite taking precautions to step carefully. It has been demonstrated in dual-task walking that age-related decline in cognitive and attentional mechanisms can compromise postural management. This is yet to be substantiated during obstacle negotiation when walking. Forty-six healthy volunteers (aged 20-79 years) stepped over obstacles in their path whilst walking and performing a verbal fluency task. Using 3D kinematic analysis we compared obstacle crossing during single (obstacle crossing only) and dual-task (obstacle crossing with verbal task) conditions. We grouped the participants into three age groups and examined age-related changes to cognitive interference on obstacle crossing. During dual-task trials, the 20-29 and 60-69 groups stepped closer to the obstacles prior to crossing, increased vertical toe-obstacle clearance, and had reduced gait variability. In these two groups there was a small dual-task decrease in verbal output. The 70-79 group applied similar dual-task stepping strategies during precrossing. However, during crossing they showed reduced vertical toe-to-obstacle clearance and increased variability of obstacle-to-heel distance. Additionally, this group did not show any significant change to verbal output across trials. These results suggest that with advanced age, increased cognitive demands are more likely to have a detrimental impact on motor performance, leading to compromised safety margins and increased variability in foot placement. We conclude that younger adults utilise a posture-preserving strategy during complex tasks but the likelihood of this strategy being used decreases with advanced age.
