Predicting treatment outcome on three measures for post-traumatic stress disorder.

The aim of the present study was to investigate predictors of treatment outcome for Posttraumatic Stress Disorder (PTSD) after treatment completion and at 15-months follow-up (n = 48), in a trial of Eye Movement Desensitisation and Reprocessing (EMDR) versus Imaginal Exposure and Cognitive Restructuring (E+CR). Factors associated with treatment outcome were investigated using regression analyses with the mean change scores in three assessor and self-rated PTSD symptomatology measures, including the Clinician-Administered PTSD Scale (CAPS), the Impact of Events Scale (IES) and the PTSD Symptom Checklist (PCL) from pre- to post-treatment and pre-treatment to follow-up as the dependent variables and demographics, trauma, clinical and personality measures as independent variables. Irrespective to outcome measures and assessment points it was found that four variables were able to predict significantly treatment outcome. These included baseline PTSD symptomatology, number of sessions, gender and therapy type. Overall, our results showed that it is difficult to use pre-treatment variables as a powerful and reliable tool for predicting treatment outcome, as significant predictors were found to be sample-specific and outcome measure-specific. Clinical relevance of the present results and directions for future research are discussed.

Predicting general well-being from self-esteem and affectivity: an exploratory study with Scottish adolescents.

The present study investigated the association between the personality constructs of self-esteem/affectivity and General Well-Being (GWB) in Scottish adolescents. A total of 425 secondary school pupils completed the P.G.I. General Well-Being Scale [Verma et al. Ind J. Clin. Psychol. 10 (1983) 299], the Hare Self-esteem Scale (HSES) [Hare, The Hare General and Area-Specific (School, Peer, and Home) Self-esteem Scale. Unpublished manuscript, Department of Sociology, SUNY Stony Brook, New York, mineo, 1985] and the Positive and Negative Affect Schedule (PANAS) [Watson et al. J Personal Soc Psychol 54 (1988a) 1063]. Combined self-esteem, positive and negative affectivity, age and gender accounted for 49.7% of the total GWB variance, 24.9% of the physical well-being variance, 41.6% of the mood/affect well-being variance, 33.3% of the anxiety well-being variance and 44.3% of the self/others well-being variance. Home self-esteem was found the strongest predictor of mood/affect and self/others well-being domains as well as well-being total. It was also the second best predictor of anxiety well-being domain. School self-esteem was the strongest predictor of physical well-being, whereas negative affectivity was the strongest predictor of anxiety well-being domain. However age and gender were not significantly associated with GWB, total or domain specific. The study adds to previous evidence regarding the high association between GWB and personality factors in adult and adolescent populations. Directions for future research are discussed.

A health assessment tool for multiple risk factors for obesity: results from a pilot study with UK adults.

OBJECTIVE: Although many individual health behaviours have been implicated in the current rise in obesity levels, their confounding or cumulative effects have yet to be established. This study piloted a measure of multiple risk factors for obesity, designed to assess their relative importance at individual and population levels. METHODS: A 100-item, user-friendly, self-report questionnaire, was completed by 80 adult volunteers (67% female, age range 19-73 years), and related to Body Mass Index (BMI). RESULTS: Dietary factors significantly related to BMI were higher amount of food consumption and more non-hunger related eating. BMI was strongly related to both negative attitudes/emotions towards and negative social influences on physical activity/exercise. Higher BMI was also related to less participation in physical activity/exercise, more sedentary leisure pursuits (e.g. TV watching) and lower general activity levels (e.g. more car usage). A regression analysis of all risk factors explained around 56% of the variance in BMI. CONCLUSION: The pilot measure was able to differentiate between weight groups on a number of risk factors. The strong associations found between BMI and attitudes, emotions and social influences on eating and activity behaviours may help explain why many diet and exercise regimes are unsuccessful. PRACTICE IMPLICATIONS: Results demonstrate that an easy-to-complete, self-report tool of multiple risk factors for obesity has potential as a health assessment tool for use by health professionals.

Adherence to medication after liver transplantation in Scotland: a pilot study.

This study assessed adherence to medication after liver transplantation and consisted of 2 components: a retrospective audit involving the examination of the Scottish national database, and a preliminary study assessing psychological factors implicated in poor adherence. In order to first establish an idea of the extent of poor adherence within the Scottish liver transplant population, a retrospective audit was carried out on all patients (N = 435) who received transplants before November 2003. Adherence was assessed by attendance at follow-up clinic appointments, blood immunosuppressant levels, and episodes of cellular rejection. It was found that attendance and immunosuppressant levels were often suboptimal and that nonadherence may have contributed to retransplantation and death. Cellular (acute) rejection after 6 months was associated with higher mortality. Explanations as to why liver transplant patients may not take their medication as recommended were then explored in detailed psychological assessments of 33 liver transplant recipients. The results indicated that low self-reported patient adherence was related to greater concerns regarding the potential adverse effects of medication, and a stronger belief that medicines in general are harmful. In addition, the greater the effect the transplantation had on patients' lives and the more it affected them emotionally, the less adherent the patients were likely to be. The results highlight potential areas that, if confirmed in a larger study, might be targeted in a psychological intervention to improve patient adherence and thereby transplantation outcomes.

The impact of knowledge and social influences on adolescents' breast-feeding beliefs and intentions.

OBJECTIVES: Many health promotion educational interventions assume that increasing knowledge directly influences beliefs, intentions and behaviour, whereas research suggests that knowledge alone is insufficient for behavioural change. Social cognition frameworks such as the Theory of Reasoned Action propose a central role for beliefs and social normative influences. This Scottish study evaluates the role of knowledge and social influences (subjective norms, exposure to breast-feeding, social barriers) on beliefs and future intentions to breast-feed or bottle-feed. Social influences from family and peers are investigated. DESIGN: A cross-sectional between-subjects observational design was used. A questionnaire was administered to a sample of 229 (46%) male and 267 (54%) female adolescents aged 11-18 years. SETTING: Participants completed questionnaires during lessons at three secondary schools in Central Scotland. RESULTS: Knowledge about health benefits of breast-feeding was generally poor. Analyses found that perceived social barriers to breast-feeding moderated the relationship between knowledge and beliefs. More knowledge, positive beliefs and supportive subjective norms also predicted future intentions to breast-feed. Parental norms exerted greater influence than peer norms on adolescents' breast-feeding beliefs. CONCLUSIONS: Knowledge and social influences are important predictors of positive breast-feeding beliefs and future intentions to breast-feed in adolescents. This has important implications for breast-feeding health promotion interventions in young people.

Earning and learning: role congruence, state/trait factors and adjustment to university life.

BACKGROUND: Undertaking term-time employment is increasingly commonplace for university students. Much research suggests that combining 'earning and learning' may be detrimental to university life, generating role conflicts, increasing stress and reducing academic success, participation and overall adjustment to university. Potential positive effects of term-time employment on well-being are often neglected. AIMS: This study adopted a balanced perspective, investigating the relationship between role congruence in academic, social and career domains and adjustment, with state and trait psychological factors as mediators/moderators. METHODS: A questionnaire measuring perceived role congruence, adjustment to university life and psychological state and trait characteristics was mailed to all undergraduates at a Scottish university during term-time. SAMPLE: Results for a subsample of 625 university students currently in term-time employment were included in this paper. RESULTS: Findings suggested that students generally perceived employment and university roles to be in balance, and there was no difference in adjustment for students whether currently in term-time employment or not. However, psychological factors, particularly positive affectivity and stress were important mediators of the relationship between role congruence and adjustment. CONCLUSIONS: Since promoting role congruence may enhance students' adjustment and well-being, the study has implications for universities, student welfare organizations and employers offering term-time employment.

A computerised guidance tree (decision aid) for hypertension, based on decision analysis: development and preliminary evaluation.

This paper discusses the piloting of a computerised decision aid that provides individualised information about hypertension to patients. The program is based on decision analysis, using decision trees as a way of structuring information. It incorporates the Framingham risk equation to assess a users' risk of coronary artery disease, together with a detailed assessment of the patient's current lifestyle and their willingness to change behaviour. Users of the program can decide how much or how little information they access. The program assesses individual's preferences for different treatment outcomes, before providing them with guidance on what might be the best treatment option for them. The program was evaluated by 10 patients with a diagnosis of mild to moderate hypertension and 8 health care professionals. Overall, both health care professionals and patients assessed the program positively. The use of a decision aid based on decision analysis may be a useful way of providing information to patients in order to promote shared decision making.

Initiation and continuation of breastfeeding: theory of planned behaviour.

AIMS: This paper reports a study investigating new mothers' subjective norms in relation to both breast- and bottle-feeding. The influence of norms on women's infant feeding decisions and the relative influence of social referents at varying degrees of social distance were assessed. BACKGROUND: Increasing breastfeeding initiation and continuation rates is a key challenge for health educators. The perceived influence of other people's views (subjective norms), including the views of women's partners and health care professionals, is an important predictor of infant feeding behaviour. METHODS: Semi-structured questionnaires were administered to 203 new mothers in central and northern Scotland and followed-up by postal questionnaire at 6 weeks. Infant feeding intentions, feeding behaviour at birth and follow-up, behavioural beliefs and subjective norms for both breastfeeding and bottle-feeding were assessed. The data were collected in 1998-1999. RESULTS: Subjective norms were important determinants of initiation and continuation of breastfeeding for breast- and bottlefeeders. Breastfeeders rated close social referents as more in favour of bottle-feeding and more against breastfeeding at follow-up, whereas bottlefeeders' ratings did not change. Partner's and nurses'/midwives' views were an important influence at baseline and follow-up. Breastfeeding 'continuers' perceived their partners as more pro-breastfeeding at 6 weeks. Discontinuers perceived more overall social pressure to bottle-feed. However, sampling limitations may have led to over-representation of the views of breastfeeders at baseline and follow-up. CONCLUSIONS: Nurses and midwives have a crucial role in communicating positive views on breastfeeding to new mothers at different time points. Future interventions to promote breastfeeding could adopt a broad social approach, encouraging positive norms for existing and potential mothers and fathers, families and people in general.

The development and preliminary evaluation of a decision aid based on decision analysis for two treatment conditions: benign prostatic hyperplasia and hypertension.

This paper discusses the development and evaluation of a computerised decision aid that provides individualised information about Benign Prostatic Hyperplasia (BPH) and Hypertension to patients. The program is based on decision analysis, using decision trees as a way of providing users with information regarding the probability of different outcomes occurring, obtaining an individual evaluation of the different outcomes, before providing guidance on what might be the 'best' option for that patient. It is intended that the program can be used as the basis for helping patients to become more involved in decisions about their medical treatment. Eight health care professionals and 19 patients (9 with BPH and 10 with Hypertension) evaluated the program. Overall it was assessed positively by both health care professionals and patients. However, before it can be integrated into health care practice, the program is to be evaluated further in a randomised trial.

Practice of and attitudes toward breast self-examination (BSE): a cross-cultural comparison between younger women in Scotland and Greece.

Breast self-examination (BSE) is a method of early detection of breast cancer. Although BSE is recommended for all women, it is mostly suitable and readily available for younger women. BSE beliefs and practices of women in Scotland, a country with organised health campaigns about BSE, were compared with those of women in Greece, a country without such campaigns. Our sample consisted of 68 university students in Scotland and Greece, aged 18 to 26 years old. All participants completed a questionnaire assessing demographics, health history, knowledge, BSE practice, health beliefs, and health-related personality. BSE practice was found to be associated with different variables across the two cultural groups. Adherence rates were found particularly higher than previous reports and BSE practice did not differ significantly between women in Scotland and Greece. Nevertheless, the two groups differed significantly in their knowledge, attitudes toward BSE, and health-related personality. On the basis of these findings, cultural factors should be considered in organising BSE campaigns. Also the present findings identified BSE-related beliefs and practices specific to younger age groups. These could be considered and addressed in order to organise BSE campaigns in Greece and improve future UK programs especially tailored for this age group.
