Using self-efficacy theory to develop interventions that help older people overcome psychological barriers to physical activity: A discussion paper

BACKGROUND Only a fifth of older people undertake a level of physical activity sufficient to lead to health benefit. Misconceptions about the ageing process and beliefs about the costs and benefits of exercise in late life may result in unnecessary self-imposed activity restriction. Thus, adhering to a physical activity can be difficult particularly when the benefits of exercise are often not immediate. Many of the barriers to engaging in physical activity among older people are attitudinal. It is therefore important to take account of the non-physical aspects of physical activity intervention programmes, such as increasing confidence. Self-efficacy is a widely applied theory used to understand health behaviour and facilitate behavioural modification, such as the increase of physical activity. AIM This paper aims to examine the ways in which self-efficacy theory might be used in intervention programmes designed to overcome psychological barriers for increasing physical activity among older people. CONCLUSION A number of studies have demonstrated that exercise self-efficacy is strongly associated with the amount of physical activity undertaken. Evidence from some trials supports the view that incorporating the theory of self-efficacy into the design of a physical activity intervention is beneficial. Physical activity interventions aimed at improving the self perception of exercise self-efficacy can have positive effects on confidence and the ability to initiate and maintain physical activity behaviour. There are a number of ways for nurses to facilitate older people to draw on the four information sources of self-efficacy: performance accomplishments, vicarious learning, verbal encouragement, and physiological and affective states. Research challenges that future studies need to address include the generalisability of exercise setting, the role of age as an effect modifier, and the need for more explicit reporting of how self-efficacy is operationalised in interventions.

Psychological effects of a low-grade abnormal cervical smear test result: anxiety and associated factors

Receipt of an abnormal cervical smear result often generates fear and confusion and can have a negative impact on a womans well-being. Most previous studies have focussed on high-grade abnormal smears. This study describes the psychological and psychosocial effects, on women, of having received a low-grade abnormal smear result. Over 3500 women recruited to TOMBOLA (Trial Of Management of Borderline and Other Low-grade Abnormal smears) participated in this study. Anxiety was assessed using the Hospital Anxiety and Depression Scale (HADS) at recruitment. Socio-demographic and lifestyle factors, locus of control and factors associated with the psychosocial impact of the abnormal smear result were also assessed. Women reported anxiety levels consistent with those found in previous studies of women with high-grade smear results. Women at highest risk of anxiety were younger, had children, were current smokers, or had the highest levels of physical activity. Interventions that focus particularly on womens understanding of smear results and pre-cancer, and/or directly address their fears about cancer, treatment and fertility might provide the greatest opportunity to reduce the adverse psychosocial impact of receiving a low-grade abnormal cervical smear result.

After-effects reported by women following colposcopy, cervical biopsies and LLETZ: results from the TOMBOLA trial.

OBJECTIVE Few studies have investigated physical after-effects of colposcopy. We compared post-colposcopy self-reported pain, bleeding, discharge and menstrual changes in women who underwent: colposcopic examination only; cervical punch biopsies; and large loop excision of the transformation zone (LLETZ). DESIGN Observational study nested within a randomised controlled trial. SETTING Grampian, Tayside and Nottingham. POPULATION Nine hundred-and-twenty-nine women, aged 20-59, with low-grade cytology, who had completed their initial colposcopic management. METHODS Women completed questionnaires on after-effects at approximately 6-weeks, and on menstruation at 4-months, post-colposcopy. MAIN OUTCOME MEASURES Frequency of pain, bleeding, discharge; changes to first menstrual period post-colposcopy. RESULTS Seven hundred-and-fifty-one women (80%) completed the 6-week questionnaire. Of women who had only a colposcopic examination, 14-18% reported pain, bleeding or discharge. Around half of women who had biopsies only and two-thirds treated by LLETZ reported pain or discharge (biopsies: 53% pain, 46% discharge; LLETZ: 67% pain, 63% discharge). The frequency of bleeding was similar in the biopsy (79%) and LLETZ groups (87%). Women treated by LLETZ reported bleeding and discharge of significantly longer duration than other women. The duration of pain was similar across management groups. Forty-three percent of women managed by biopsies and 71% managed by LLETZ reported some change to their first period post-colposcopy, as did 29% who only had a colposcopic examination. CONCLUSIONS Cervical punch biopsies and, especially, LLETZ carry a substantial risk of after-effects. After-effects are also reported by women managed solely by colposcopic examination. Ensuring that women are fully informed about after-effects may help to alleviate anxiety and provide reassurance, thereby minimising the harms of screening.

Developing a questionnaire to measure the psychosocial impact of an abnormal cervical smear result and its subsequent management: the TOMBOLA (Trial Of Management of Borderline and Other Low-grade Abnormal smears) trial

This paper describes the process of developing and testing a new questionnaire, Process Outcome Specific Measure (POSM), including an assessment of its content validity and reliability. The questionnaire was developed within the context of Trial Of Management of Borderline and Other Low-grade Abnormal smears (TOMBOLA) to assess the psychosocial impact of a low-grade abnormal cervical smear result and the subsequent management. A literature search, focus groups and thorough pre-testing involving experts and patients resulted in a short (15-item), easily completed and understood questionnaire. Questions address issues including cancer, health, fertility and sexual concerns. Repeatability was assessed in 110 TOMBOLA recruits using weighted κ; all but one of the questions showed levels of reliability near to, or above, 0.5. Cronbach’s standardised α was 0.73, indicating acceptable internal consistency. Each POSM item was correlated with the anxiety and depression sub-scales of the Hospital Anxiety Depression Scale (HADS). All except one of the questions correlated more highly with the total POSM score than with the HADS sub-scales thus indicating discriminant validity. The POSM will enable comparison of the alternative management policies for low-grade cervical smears in terms of the benefits (or otherwise) perceived by the women managed by these policies.

Ethnicity and participation in cancer self-help groups.

Objectives: Investigations of the benefits of membership of a cancer self‐help group have suggested that it leads to improved sense of support, increased ability to deal with life‐events, and decreased anxiety, confusion, depression and helplessness. However, some evidence suggests that people from black and ethnic groups are less likely to join a cancer self‐help group. The main aims of the reported study were: to explore possible reasons why people from some ethnic groups have not participated in self‐help to the same extent as the rest of the community; and to identify ways in which participation of people from ethnic groups can be increased.

REFINE (REducing Falls in In-patieNt Elderly) using bed and bedside chair pressure sensors linked to radio-pagers in acute hospital care: a randomised controlled trial

Background: falls in hospitals are a major problem and contribute to substantial healthcare burden. Advances in sensor technology afford innovative approaches to reducing falls in acute hospital care. However, whether these are clinically effective and cost effective in the UK setting has not been evaluated. Methods: pragmatic, parallel-arm, individual randomised controlled trial of bed and bedside chair pressure sensors using radio-pagers (intervention group) compared with standard care (control group) in elderly patients admitted to acute, general medical wards, in a large UK teaching hospital. Primary outcome measure number of in-patient bedside falls per 1,000 bed days. Results: 1,839 participants were randomised (918 to the intervention group and 921 to the control group). There were 85 bedside falls (65 fallers) in the intervention group, falls rate 8.71 per 1,000 bed days compared with 83 bedside falls (64 fallers) in the control group, falls rate 9.84 per 1,000 bed days (adjusted incidence rate ratio, 0.90; 95% confidence interval [CI], 0.66–1.22; P = 0.51). There was no significant difference between the two groups with respect to time to first bedside fall (adjusted hazard ratio (HR), 0.95; 95% CI: 0.67–1.34; P= 0.12). The mean cost per patient in the intervention group was £7199 compared with £6400 in the control group, mean difference in QALYs per patient, 0.0001 (95% CI: −0.0006–0.0004, P= 0.67). Conclusions: bed and bedside chair pressure sensors as a single intervention strategy do not reduce in-patient bedside falls, time to first bedside fall and are not cost-effective in elderly patients in acute, general medical wards in the UK.

‘Practising under your own Pin’– a description of the transition experiences of newly qualified midwives

AIM Transition experiences of newly qualified midwives were examined in depth during the third phase of a UK evaluation study of midwifery education. BACKGROUND The fitness to practise and the retention of newly qualified nursing and midwifery graduates are pressing concerns for health care managers. The advantages of preceptorship are reported in the literature but the content and timing of schemes remain unclear. METHODS A semi-structured diary was kept for up to 6 months by 35 newly qualified midwives in 18 work sites covering all countries in the UK. The preceptor and supervisor of midwives for each newly qualified midwife completed short questionnaires about their preceptees performance, and a further sub-sample of newly qualified midwives and preceptors participated in a semi-structured interview. Data were analysed to elicit aspects of newly qualified midwives transition experiences. RESULTS Findings confirm that structured preceptorship schemes are not widely available. Newly qualified midwives primarily obtained transition support from members of the midwifery team. CONCLUSION Although perceived as competent, there is no demarcation point in becoming confident to practise as a registered practitioner. Implications for managers include the importance of a supportive culture within clinical teams for successful transition and the introduction of structured preceptorship schemes facilitated by appropriate rotation patterns.

The impact of injuries study. multicentre study assessing physical, psychological, social and occupational functioning post injury - a protocol

BackgroundLarge numbers of people are killed or severely injured following injuries each year and these injuries place a large burden on health care resources. The majority of the severely injured are not fully recovered 12-18 months later. Psychological disorders are common post injury and are associated with poorer functional and occupational outcomes. Much of this evidence comes from countries other than the UK, with differing health care and compensation systems. Early interventions can be effective in treating psychological morbidity, hence the scale and nature of the problem and its impact of functioning in the UK must be known before services can be designed to identify and manage psychological morbidity post injury.Methods/DesignA longitudinal multi-centre study of 680 injured patients admitted to hospital in four areas across the UK: Nottingham, Leicester/Loughborough, Bristol and Surrey. A stratified sample of injuries will ensure a range of common and less common injuries will be included. Participants will complete a baseline questionnaire about their injury and pre-injury quality of life, and follow-up questionnaires 1, 2, 4, and 12 months post injury. Measures will include health and social care utilisation, perceptions of recovery, physical, psychological, social and occupational functioning and health-related quality of life. A nested qualitative study will explore the experiences of a sample of participants, their carers and service providers to inform service design.DiscussionThis study will quantify physical, psychological, social and occupational functioning and health and social care utilisation following a range of different types of injury and will assess the impact of psychological disorders on function and health service use. The findings will be used to guide the development of interventions to maximise recovery post injury.

Introducing HPV Triage into the English Cervical Cancer Screening Program: Consequences for Participation

ABSTRACT Objective: To predict the likely impact of adding human papillomavirus (HPV) triage for minor abnormalities on participation in the English cervical cancer screening program. Method: Contingent valuations of the existing Pap program and a possible HPV-augmented screening program, obtained from questionnaires completed by 1141 women in east-central England. Results: The value of participating in Pap screening was negatively associated with age, positively associated with educational level, and positively associated with the level of household income. Higher levels of worry about cervical cancer were associated with higher valuations of screening. Adding HPV-based triage to the Pap program lowered the value of screening participation for only two women, whereas for the sample as a whole, it increased the average valuation by about 47 per cent. Supposedly-negative characteristics of HPV testing, when described, were expected to trigger psychosocial concerns in respondents and thereby give rise to significant decreases in valuations of participating in a Pap-plus-HPV program. For most women, however, such information changed their valuations of participation in screening little, if at all. Conclusions: Accepting the proposition that higher contingent valuations indicate stronger behavioural preferences, our results offer insubstantial grounds for believing that the inclusion of HPV triage would detrimentally affect participation in Pap screening for cervical cancer.

Long-term psychosocial impact of alternative management policies in women with low-grade abnormal cervical cytology referred for colposcopy: a randomised controlled trial.

Background:The debate continues regarding the best management for women with low-grade abnormal cervical cytology attending colposcopy. We compared psychosocial outcomes of alternative management policies in these women.Methods:In all, 989 women, aged 20–59 years, with low-grade abnormal cytology, were randomised to immediate large loop excision (LLETZ) or two to four targeted punch biopsies taken immediately with recall for LLETZ if these showed cervical intra-epithelial neoplasia 2/3. At 6 weeks after the last procedure, women completed the hospital anxiety and depression scale (HADS) and the impact of event scale (IES). At 12, 18, 24 and 30 months post recruitment, women completed the HADS and process outcome specific measure (POSM). Prevalence of significant depression (⩾8), significant anxiety (⩾11) and distress (⩾9) and median POSM scores were compared between arms. Multivariate odds ratios (ORs) for immediate LLETZ vs biopsy and recall were computed.Results:Over the entire follow-up, there was no significant difference between arms in cumulative prevalence or risk of significant depression (OR=0.78, 95% CI 0.52–1.17) or significant anxiety (OR=0.83, 95% CI 0.57–1.19). At 6 weeks post procedure, distress did not differ significantly between arms. At later time points, 8–11% had significant depression and 14–16% had significant anxiety but with no differences between arms. The POSM scores did not differ between the arms.Conclusions:There is no difference in long- or short-term psychosocial outcomes of immediate LLETZ and punch biopsies with selective recall.
