Purpose: After stroke, physical activity and physical fitness levels are low, impacting on health, activity and participation. It is unclear how best to support stroke survivors to increase physical activity. Little is known about the barriers and facilitators to physical activity after stroke. Thus, our aim was to explore stroke survivors' perceived barriers and facilitators to physical activity. Methods: Semi-structured interviews with 13 ambulatory stroke survivors exploring perceived barriers and facilitators to physical activity post stroke were conducted in participants' homes, audio-recorded and transcribed verbatim. The Theoretical Domains Framework (TDF) informed content analysis of the interview transcripts. Results: Data saturation was reached after interviews with 13 participants (median age of 76 years (inter-quartile range (IQR) = 69-83 years). The median time since stroke was 345 d (IQR = 316-366 d). The most commonly reported TDF domains were "beliefs about capabilities", "environmental context and resources" and "social influence". The most commonly reported perceived motivators were: social interaction, beliefs of benefits of exercise, high self-efficacy and the necessity of routine behaviours. The most commonly reported perceived barriers were: lack of professional support on discharge from hospital and follow-up, transport issues to structured classes/interventions, lack of control and negative affect. Conclusions: Stroke survivors perceive several different barriers and facilitators to physical activity. Stroke services need to address barriers to physical activity and to build on facilitators to promote physical activity after stroke.
Stress amongst nurses working in a healthcare telephone-advice service: Relationship with job satisfaction, intention to leave, sickness absence, and performance
(Blackwell, 2012-07) Farquharson, Barbara; Allan, Julia; Johnston, Derek; Johnston, Marie; Choudhary, Carolyn J.; Jones, Martyn
explored whether stress related to performance, sickness absence, and intention to leave. Background. Nurses report high levels of stress, as do call-centre workers. The emergence of telephone health advice services means many nurses now work in call-centres, doing work that differs markedly from traditional nursing roles. Stress associated with these roles could have implications for nurses, patients, and service provision. Design. This paper reports cross-sectional survey results. The design of the overall study included longitudinal elements. Method. A comprehensive study of stress was conducted amongst nurses working for a telephone-advice service in Scotland (2008-2010). All nurse-advisors were approached by letter and invited to participate. A total of 152 participants (33%) completed a questionnaire including General Health Questionnaire-12, Work Family Conflict Questionnaire, Job Satisfaction Scale and a measure of intention to leave the telephone-advice service and rated the perceived stress of 2 working shifts. Nurses' employers provided data on sickness absence and performance. Results. Overall levels of psychological distress were similar to those found amongst Scottish women generally. In multiple regression, work-family conflict was identified as a significant predictor of job satisfaction and intention to leave, and significantly related to sickness absence. There were significant correlations between General Health Questionnaire scores and perceived stress of shifts and some performance measures. Conclusions. Work-family conflict is a significant predictor of job satisfaction, intention to leave, and sickness absence amongst telephone helpline nurses. Minimizing the impact of nurses' work on their home lives might reduce turnover and sickness absence. 2012 Blackwell Publishing Ltd
