Rumination and behavioural factors in Parkinson's disease depression

OBJECTIVE

Parkinson's disease is associated with high rates of depression. There is growing interest in non-pharmacological management including psychological approaches such as Cognitive Behaviour Therapy. To date, little research has investigated whether processes that underpin cognitive models of depression, on which such treatment is based, apply in patients with Parkinson's disease. The study aimed to investigate the contribution of core psychological factors to the presence and degree of depressive symptoms.

METHODS

104 participants completed questionnaires measuring mood, motor disability and core psychological variables, including maladaptive assumptions, rumination, cognitive-behavioural avoidance, illness representations and cognitive-behavioural responses to symptoms.

RESULTS

Regression analyses revealed that a small number of psychological factors accounted for the majority of depression variance, over and above that explained by overall disability. Participants reporting high levels of rumination, avoidance and symptom focusing experienced more severe depressive symptoms. In contrast, pervasive negative dysfunctional beliefs did not independently contribute to depression variance.

CONCLUSION

Specific cognitive (rumination and symptom focusing) and behavioural (avoidance) processes may be key psychological markers of depression in Parkinson's disease and therefore offer important targets for tailored psychological interventions.

Living with joint hypermobility syndrome: patient experiences of diagnosis, referral and self-care

BACKGROUND

Musculoskeletal problems are common reasons for seeking primary health care. It has been suggested that many people with 'everyday' non-inflammatory musculoskeletal problems may have undiagnosed joint hypermobility syndrome (JHS), a complex multi-systemic condition. JHS is characterized by joint laxity, pain, fatigue and a wide range of other symptoms. Physiotherapy is usually the preferred treatment option for JHS, although diagnosis can be difficult. The lived experience of those with JHS requires investigation.

OBJECTIVE

The aim of the study was to examine patients' lived experience of JHS, their views and experiences of JHS diagnosis and management.

METHODS

Focus groups in four locations in the UK were convened, involving 25 participants with a prior diagnosis of JHS. The focus groups were audio recorded, fully transcribed and analysed using the constant comparative method to inductively derive a thematic account of the data.

RESULTS

Pain, fatigue, proprioception difficulties and repeated cycles of injury were among the most challenging features of living with JHS. Participants perceived a lack of awareness of JHS from health professionals and more widely in society and described how diagnosis and access to appropriate health-care services was often slow and convoluted. Education for patients and health professionals was considered to be essential.

CONCLUSIONS

Timely diagnosis, raising awareness and access to health professionals who understand JHS may be particularly instrumental in helping to ameliorate symptoms and help patients to self-manage their condition. Physiotherapists and other health professionals should receive training to provide biopsychosocial support for people with this condition.

Maternal and childhood psychological factors predict chronic disabling fatigue at age 13 years

PURPOSE

To investigate whether premorbid maternal and childhood psychological problems are risk factors for chronic disabling fatigue at age 13 years among children in the Avon Longitudinal Study of Parents and Children birth cohort.

METHODS

Chronic disabling fatigue was defined as fatigue of at least 3-month, and up to 5-year, duration that prevented school attendance or hobbies/sport/leisure activities, and for which other causes were not identified. Maternal psychological factors were symptoms of anxiety and depression assessed up to eight times between pregnancy and age 6 years. We investigated critical periods for maternal effects and effects of paternal depression at three time points. Child psychological factors included internalizing and externalizing problems and upsetting life events occurring at age 7-8 years.

RESULTS

Of 5,657 children, 110 (1.9%) had chronic disabling fatigue at age 13 years. Maternal anxiety (adjusted odds ratio [AOR], 1.19; 95% confidence interval [CI], 1.09-1.31 per episode), maternal depression (AOR, 1.24; CI, 1.11-1.39 per episode), child psychological problems (AOR, 1.19; CI, 1.00-1.41 per problem), and upsetting events (AOR, 1.22; CI, .99-1.58 per event) were associated with chronic disabling fatigue. Associations of child psychological problems and upsetting events were attenuated (AOR, 1.12; CI, .93-1.33 per problem; AOR, 1.19; CI, .94-1.52 per event) after further adjusting for maternal anxiety and depression.

CONCLUSIONS

Pediatricians need to be aware that children whose mothers experience anxiety and/or depression between pregnancy and child's age 6 years have an increased risk of developing chronic disabling fatigue in early adolescence. Conversely, clinicians need to be alert to fatigue in children whose mothers have longstanding anxiety and depression. These findings suggest the importance of family-based approaches to treatment.

Cortisol output in adolescents with chronic fatigue syndrome: pilot study on the comparison with healthy adolescents and change after cognitive behavioural guided self-help treatment

OBJECTIVE

This study examined cortisol in adolescents with chronic fatigue syndrome (CFS) compared to healthy adolescents and changes in cortisol after cognitive behavioural guided self-help treatment. Exploratory analyses investigated the association between cortisol output and psychological variables.

METHODS

Salivary cortisol was measured upon awakening, at 15, 30, 45 and 60 min afterwards and at 12 noon, 4:00 p.m. and 8:00 p.m., in adolescents with CFS and healthy controls (HC). Groups were matched for age, gender, menarche status, menstrual cycle and awakening time. Twenty-four adolescents with CFS provided saliva samples six months after treatment. The main outcome measure was total salivary output over the day, calculated by area under the curve (AUC). The salivary awakening response was also assessed.

RESULTS

Cortisol output over the day was significantly lower in the CFS group (n=46) than in healthy controls (n=33). Within the CFS group, lower daily cortisol output was associated with higher self-reported perfectionist striving and prosocial behaviour. There were no significant group differences in the awakening response (n=47 CFS versus n=34 HC). After treatment, adolescents with CFS (n=21) showed a significant increase in daily cortisol output, up to normal levels.

CONCLUSION

The reduced daily cortisol output in adolescents with CFS is in line with adult findings. Associations between reduced cortisol output and two psychological variables-perfectionism and prosocial behaviour-are consistent with cognitive behavioural models of chronic fatigue syndrome. The mild hypocortisolism is reversible; cortisol output had returned to healthy adolescent levels by six months after cognitive behavioural guided self-help treatment.

Protocol for a proof of concept randomized controlled trial of cognitive-behavioural therapy for adult ADHD as a supplement to treatment as usual, compared with treatment as usual alone

BACKGROUND

ADHD is prevalent in adults and frequently associated with impairment and distress. While medication is often the first line of treatment a high proportion of people with the condition are not fully treated by medication alone, cannot tolerate medication or do not wish to take it. Preliminary studies suggest that psychosocial approaches are a promising adjunctive or alternative treatment option. To date, individual cognitive-behaviour therapy (CBT) has been found to be efficacious in three randomized controlled trials (RCTs). There is a need for more RCTs to be carried out in order to replicate these results in different sites, to further investigate the acceptability and feasibility of CBT in this population and to further develop CBT approaches based on a psychological model. This randomized controlled trial investigates the efficacy of individual, formulation-based CBT when added to treatment-as-usual as compared with treatment as usual alone.

METHODS/DESIGN

Sixty patients with a diagnosis of adult ADHD attending a specialist clinic are randomly allocated to 1 of 2 treatments, 'Treatment as Usual' (TAU) or TAU plus 16 sessions individual CBT (TAU + CBT). In the TAU + CBT, the first 15 sessions take place over 30 weeks with a 16th 'follow-up' session at 42 weeks. Outcomes are assessed at 30 weeks and 42 weeks following randomization. The two primary outcomes are self-rated ADHD symptoms and functioning (occupational and social). Secondary outcomes include distress, mood, ADHD-related cognitions, ADHD-related behaviours and informant-rated ADHD symptoms. The primary analysis will include all participants for whom data is available and will use longitudinal regression models to compare treatments. Secondary outcomes will be analysed similarly.

DISCUSSION

The results of the study will provide information about a) whether CBT adds benefit over and above TAU for ADHD and, b) if CBT is found to be efficacious, potential mechanisms of change and predictors of efficacy.

Mechanisms of change underlying the efficacy of cognitive behaviour therapy for chronic fatigue syndrome in a specialist clinic: a mediation analysis

BACKGROUND

Several randomized controlled trials (RCTs) have shown that cognitive behavioural psychotherapy (CBT) is an efficacious treatment for chronic fatigue syndrome (CFS). However, little is known about the mechanisms by which the treatment has its effect. The aim of this study was to investigate potential mechanisms of change underlying the efficacy of CBT for CFS. We applied path analysis and introduce novel model comparison approaches to assess a theoretical CBT model that suggests that fearful cognitions will mediate the relationship between avoidance behaviour and illness outcomes (fatigue and social adjustment).

METHOD

Data from 389 patients with CFS who received CBT in a specialist service in the UK were collected at baseline, at discharge from treatment, and at 3-, 6- and 12-month follow-ups. Path analyses were used to assess possible mediating effects. Model selection using information criteria was used to compare support for competing mediational models.

RESULTS

Path analyses were consistent with the hypothesized model in which fear avoidance beliefs at the 3-month follow-up partially mediate the relationship between avoidance behaviour at discharge and fatigue and social adjustment respectively at 6 months.

CONCLUSIONS

The results strengthen the validity of a theoretical model of CBT by confirming the role of cognitive and behavioural factors in CFS.

Telephone-based guided self-help for adolescents with chronic fatigue syndrome: A non-randomised cohort study

The aim of this study was to gain preliminary evidence about the efficacy of a new telephone-based guided self-help intervention, based on cognitive-behavioural principles, which aimed to reduce fatigue and improve school attendance in adolescents with chronic fatigue syndrome (CFS). A non-randomised cohort design was used, with a two-month baseline period. Sixty-three 11-18 year-old participants recruited from a specialist CFS unit received the intervention. Participants received six half-hour fortnightly telephone sessions and two follow-up sessions. Fatigue and school attendance were the main outcomes and the main time point for assessing outcome was 6 months post-treatment. Using multi-level modelling, a significant decrease in fatigue was found between pre-treatment and 6 month follow-up, treatment effect estimate = - 5.68 (-7.63, -3.72), a large effect size (Cohen's d = 0.79). The decrease in fatigue between pre and post-treatment was significantly larger than between baseline and pre-treatment. A significant increase in school attendance was found between pre-treatment and 6 month follow-up, effect estimate = 1.38 (0.76, 2.00), a medium effect size (d = -0.48). univariate logistic regression found baseline perfectionism to be associated with better [corrected] school attendance at six-month follow-up. In conclusion, telephone-based guided self-help is an acceptable minimal intervention which is efficacious in reducing fatigue in adolescents with CFS.

Mindfulness-based cognitive therapy for people with chronic fatigue syndrome still experiencing excessive fatigue after cognitive behaviour therapy: a pilot randomized study

Cognitive behaviour therapy (CBT) is an effective treatment for chronic fatigue syndrome (CFS; sometimes known as myalgic encephalomyelitis). However, only a minority of patients fully recover after CBT; thus, methods for improving treatment outcomes are required. This pilot study concerned a mindfulness-based cognitive therapy (MBCT) intervention adapted for people with CFS who were still experiencing excessive fatigue after CBT. The study aimed to investigate the acceptability of this new intervention and the feasibility of conducting a larger-scale randomized trial in the future. Preliminary efficacy analyses were also undertaken. Participants were randomly allocated to MBCT or waiting list. Sixteen MBCT participants and 19 waiting-list participants completed the study, with the intervention being delivered in two separate groups. Acceptability, engagement and participant-rated helpfulness of the intervention were high. Analysis of covariance controlling for pre-treatment scores indicated that, at post-treatment, MBCT participants reported lower levels of fatigue (the primary clinical outcome) than the waiting-list group. Similarly, there were significant group differences in fatigue at 2-month follow-up, and when the MBCT group was followed up to 6 months post-treatment, these improvements were maintained. The MBCT group also had superior outcomes on measures of impairment, depressed mood, catastrophic thinking about fatigue, all-or-nothing behavioural responses, unhelpful beliefs about emotions, mindfulness and self-compassion. In conclusion, MBCT is a promising and acceptable additional intervention for people still experiencing excessive fatigue after CBT for CFS, which should be investigated in a larger randomized controlled trial.

KEY PRACTITIONER MESSAGE

Only about 30% of people with chronic fatigue syndrome (CFS) recover after cognitive behaviour therapy (CBT); thus, methods for improving treatment outcomes are needed. This is the first pilot randomized study to demonstrate that a mindfulness-based intervention was associated with reduced fatigue and other benefits for people with CFS who were still experiencing excessive fatigue after a course of CBT. Levels of acceptability, engagement in the intervention and rated helpfulness were high. A larger-scale randomized controlled trial is required.

An experimental investigation of factors involved in the decision to undertake genetic testing for schizophrenia

BACKGROUND

The psychological issues surrounding genetic testing, particularly decision-making processes, are not well understood. Previous studies suggest that apparently "nondirective" strategies intended to help individuals consider the consequences of undergoing predictive testing for physical illness can influence the decision.

AIMS

To investigate the influence of selectively focussing on different aspects of previously provided information concerning genetic testing for schizophrenia.

METHOD

Community participants (n = 120) rated how likely they would be to arrange to have a genetic test for schizophrenia if it were available, before and after being given detailed information about schizophrenia and the implications of testing. Participants were then randomly allocated to four groups, and were implicitly focused on the negative issues (negative group), the positive issues (positive group), both the negative and positive issues (all-focusing group) or schizophrenia-irrelevant health-related issues (control group). All issues on which the experimental groups focussed were included in the information provided and the form of questioning meets current definitions of nondirectiveness.

RESULTS

Hypothetical decisions whether to arrange a genetic test for schizophrenia were influenced by the issues on which participants had focused; the positive group were more likely to say they would be tested relative to the other groups.

CONCLUSIONS

Decisions about genetic testing for schizophrenia were influenced by the specific issues on which individuals were encouraged to focus at that time.

The Beliefs about Emotions Scale: validity, reliability and sensitivity to change

OBJECTIVE

Beliefs about the unacceptability of experiencing or expressing negative emotions have been noted in individuals with a range of problems, including chronic fatigue syndrome (CFS), irritable bowel syndrome, somatization disorder, depression, eating disorders, social phobia, posttraumatic stress disorder, and borderline personality disorder. These beliefs are likely to have implications for emotion regulation and processing, and are addressed explicitly or implicitly within many therapies including cognitive behavior therapy (CBT), mindfulness-based cognitive therapy (MBCT), and Acceptance and Commitment Therapy (ACT). This article describes the development, validation, and internal reliability of the Beliefs about Emotions Scale (BES), a self-report questionnaire to assess such beliefs.

METHODS

The new scale was completed by people with CFS (n=121) and healthy controls (n=73). Twenty-two individuals with CFS completed the scale before and after CBT.

RESULTS

People with CFS had significantly higher scores on this new questionnaire than healthy controls. Principal components analysis identified one factor, and the scale had high internal consistency (0.91). Scores on the BES were most highly correlated with a measure of negative perfectionism (r=0.59) and also showed significant correlations with measures of dysfunctional attitudes, self-sacrifice, depression, anxiety, and fatigue. When completed before and after CBT for CFS, the questionnaire was sufficiently sensitive to detect a significant reduction in endorsement of unhelpful beliefs about emotions.

CONCLUSION

The new Beliefs about Emotions Scale showed good internal reliability, validity and sensitivity to change.

The neural correlates of fatigue: an exploratory imaginal fatigue provocation study in chronic fatigue syndrome

BACKGROUND

Fatigue is the central symptom in chronic fatigue syndrome (CFS) and yet very little is known about its neural correlates. The aim of this study was to explore the functional brain response, using functional magnetic resonance imaging (fMRI), to the imaginal experience of fatigue in CFS patients and controls.

METHOD

We compared the blood oxygen level dependent (BOLD) responses of 12 CFS patients and 11 healthy controls to a novel fatigue provocation procedure designed to mimic real-life situations. A non-fatiguing anxiety-provoking condition was also included to control for the non-specific effects of negative affect.

RESULTS

During the provocation of fatigue, CFS patients reported feelings of both fatigue and anxiety and, compared to controls, they showed increased activation in the occipito-parietal cortex, posterior cingulate gyrus and parahippocampal gyrus, and decreased activation in dorsolateral and dorsomedial prefrontal cortices. The reverse pattern of findings was observed during the anxiety-provoking scenarios.

CONCLUSIONS

The results may suggest that, in CFS patients, the provocation of fatigue is associated with exaggerated emotional responses that patients may have difficulty suppressing. These findings are discussed in relation to the cognitive-behavioural model of CFS.

Cognitive-behaviour therapy for chronic fatigue syndrome: Comparison of outcomes within and outside the confines of a randomised controlled trial

Outcomes for cognitive-behaviour therapy (CBT) in randomised controlled trials (RCTs) have rarely been compared to those in routine clinical practice. Taking the case of CBT for chronic fatigue syndrome (CFS), we evaluated the results of a successful RCT against those of the same treatment given in the same setting as part of routine practice. Fatigue and social adjustment scores were compared for patients who received CBT for CFS as part of a RCT (N=30) and patients who received CBT as part of everyday clinical practice (N=384). The results in the RCT were superior to those in routine clinical practice. Between pre-treatment and 6-month follow-up, the RCT showed a larger reduction in fatigue and greater improvement in social adjustment than those in routine treatment. The changes in fatigue scores were similar for both groups during treatment but were greater in the RCT between post-treatment and follow-up. Potential reasons for the superior results of the RCT include patient selection, therapist factors and the use of a manualised treatment protocol. Practitioners need to pay particular attention to relapse prevention and ensuring adequate follow-up in addition to encouraging patients to continue with cognitive-behavioural strategies once treatment has ended.

Incidence, prognosis, and risk factors for fatigue and chronic fatigue syndrome in adolescents: a prospective community study

OBJECTIVE

The objective of this study was to describe the incidence, prevalence, risk factors, and prognosis of fatigue, chronic fatigue, and chronic fatigue syndrome in 11- to 15-year-olds.

METHODS

A random general population sample (n = 842) of British adolescents and their parents were assessed at baseline and 4 to 6 months later. The main outcomes were fatigue, chronic fatigue, and chronic fatigue syndrome, operationally defined.

RESULTS

The incidence over 4 to 6 months was 30.3% for fatigue, 1.1% for chronic fatigue, and 0.5% for chronic fatigue syndrome. The point prevalence was 34.1% and 38.1% for fatigue, 0.4% and 1.1% for chronic fatigue, and 0.1% and 0.5% for chronic fatigue syndrome at time 1 and time 2, respectively. Of participants who were fatigued at time 1, 53% remained fatigued at time 2. The 3 cases of chronic fatigue and 1 case of chronic fatigue syndrome at time 1 had recovered by time 2. Higher risk for development of chronic fatigue at time 2 was associated with time 1 anxiety or depression, conduct disorder, and maternal distress; in multivariate analysis, baseline anxiety or depression remained a significant predictor of chronic fatigue. Increased risk for development of fatigue at time 2 was associated with time 1 anxiety or depression, conduct disorder, and older age; in multivariate analyses, these factors and female gender all were significant predictors of fatigue.

CONCLUSIONS

The incidence rates for chronic fatigue and chronic fatigue syndrome in this adolescent sample were relatively high, but the prognosis for these conditions was good. This prospective study provides evidence for an association between emotional/behavioral problems and subsequent onset of fatigue/chronic fatigue.

Probing the working memory system in chronic fatigue syndrome: a functional magnetic resonance imaging study using the n-back task

OBJECTIVE

Up to 90% of patients with chronic fatigue syndrome (CFS) report substantial cognitive difficulties. However, objective evidence supporting these claims is inconsistent. The present functional magnetic resonance imaging study examined the neural correlates of working memory in patients with CFS compared with controls.

METHODS

Seventeen patients with CFS and 12 healthy control subjects were scanned while performing a parametric version of the n-back task (0-, 1-, 2-, and 3-back).

RESULTS

Both groups performed comparably well and activated the verbal working memory network during all task levels. However, during the 1-back condition, patients with CFS showed greater activation than control subjects in medial prefrontal regions, including the anterior cingulate gyrus. Conversely, on the more challenging conditions, patients with CFS demonstrated reduced activation in dorsolateral prefrontal and parietal cortices. Furthermore, on the 2- and 3-back conditions, patients but not control subjects significantly activated a large cluster in the right inferior/medial temporal cortex. Trend analyses of task load demonstrated statistically significant differences in brain activation between the two groups as the demands of the task increased.

CONCLUSIONS

These results suggest that patients with CFS show both quantitative and qualitative differences in activation of the working memory network compared with healthy control subjects. It remains to be determined whether these findings stay stable after successful treatment.

Applying a cognitive behavioral model of health anxiety in a cancer genetics service

A cognitive-behavioral model of health anxiety was used to investigate reactions to genetic counseling for cancer. Participants (N = 218) were asked to complete a questionnaire beforehand and 6 months later. There was an overall decrease in levels of cancer-related anxiety, although 24% of participants showed increased cancer-related anxiety at follow-up. People who had a general tendency to worry about their health reported more cancer-related anxiety than those who did not at both time points. This health-anxious group also showed a postcounseling anxiety reduction, whereas the others showed no significant change. Participants with breast or ovarian cancer in their family were more anxious than participants with colon cancer in their family. Preexisting beliefs were significant predictors of anxiety, consistent with a cognitive-behavioral approach.

The effects of self-focused rumination on global negative self-judgements in depression

Previous research in dysphoric participants has found that compared with distraction, rumination inductions are associated with increased levels of cognitive distortions and overgeneral autobiographical memories. Watkins and Teasdale ((2001) Journal of Abnormal Psychology, 110, 353-357) investigated which component of rumination was responsible for this effect in overgeneral memory, and found two distinct modes of ruminative self-focus, with analytical, evaluative self-focus maintaining overgeneral memory, whereas self-focus low in analytical thinking reduced overgeneral memory. The present study compared the effects of these two distinct forms of self-focused rumination with another measure of overgeneral thinking--global negative self-judgements. Thirty depressed participants and thirty never-depressed participants were randomly allocated to 'analytic' (high analysis) or 'experiential' (low analysis) self-focused manipulations. As predicted, in depressed participants, the analytical self-focus condition increased ratings of the self as worthless and incompetent pre- to post-manipulation, whereas the experiential self-focus condition resulted in no significant change in such judgements. The results are consistent with the hypothesis that an analytical mode of self-focused rumination may be particularly maladaptive in depression.

Treatments for chronic fatigue syndrome

AIMS

To review studies evaluating the treatment of chronic fatigue and chronic fatigue syndrome, to describe predictors of response to treatment and to discuss the role of the occupational health physician.

METHODS

A literature search was carried out using Medline and PsychInfo.

RESULTS

Studies evaluating cognitive behaviour therapy, graded exercise therapy, pharmacological interventions (e.g. antidepressants and corticosteroids), immunological interventions and nutritional supplements were reviewed. The most promising results have been found with cognitive behaviour therapy and graded exercise therapy, and some predictors of outcome have been identified. Most of the other interventions were evaluated in just one or two studies and therefore evidence is insufficient to draw firm conclusions.

CONCLUSIONS

By applying the models of fatigue that form the bases for cognitive behaviour therapy and graded exercise therapy, occupational health physicians may play an important role in helping the patients with chronic fatigue syndrome to reduce their symptoms, improve their functioning and return to work.

The Health Anxiety Inventory: development and validation of scales for the measurement of health anxiety and hypochondriasis

BACKGROUND

A self-rated measure of health anxiety should be sensitive across the full range of intensity (from mild concern to frank hypochondriasis) and should differentiate people suffering from health anxiety from those who have actual physical illness but who are not excessively concerned about their health. It should also encompass the full range of clinical symptoms characteristic of clinical hypochondriasis. The development and validation of such a scale is described.

METHOD

Three studies were conducted. First, the questionnaire was validated by comparing the responses of patients suffering from hypochondriasis with those suffering from hypochondriasis and panic disorder, panic disorder, social phobia and non-patient controls. Secondly, a state version of the questionnaire was administered to patients undergoing cognitive-behavioural treatment or wait-list in order to examine the measure's sensitivity to change. In the third study, a shortened version was developed and validated in similar types of sample, and in a range of samples of people seeking medical help for physical illness.

RESULTS

The scale was found to be reliable and to have a high internal consistency. Hypochondriacal patients scored significantly higher than anxiety disorder patients, including both social phobic patients and panic disorder patients as well as normal controls. In the second study, a 'state' version of the scale was found to be sensitive to treatment effects, and to correlate very highly with a clinician rating based on an interview of present clinical state. A development and refinement of the scale (intended to reflect more fully the range of symptoms of and reactions to hypochondriasis) was found to be reliable and valid. A very short (14 item) version of the scale was found to have comparable properties to the full length scale.

CONCLUSIONS

The HAI is a reliable and valid measure of health anxiety. It is likely to be useful as a brief screening instrument, as there is a short form which correlates highly with the longer version.

Prediction of psychological reactions to bone density screening for osteoporosis using a cognitive-behavioral model of health anxiety

Pre-screening measures derived from a cognitive-behavioral theory of health anxiety were significant predictors of individual differences in post-screening reactions to a health screening procedure, bone densitometry. Predictors included specific illness beliefs (vulnerability, severity/consequences, coping and treatment) and general health anxiety measures. Three months after a low bone mineral density (BMD) result, women with high levels of pre-existing general health anxiety gave higher ratings of anxiety about osteoporosis and perceived likelihood of developing osteoporosis than women with low levels of preexisting health anxiety, even though the two groups' initial ratings had not differed significantly. Women with a low BMD result generally showed "minimization" of the seriousness of low BMD but women with very high levels of pre-existing health anxiety did not. After a high BMD result, highly health anxious women were only temporarily reassured. The results were consistent with the cognitive-behavioral analysis of health anxiety.

The effect of nondirective questioning on women's decisions whether to undergo bone density screening: an experimental study

This study investigated the effects of nondirective counseling on health screening decisions. Ninety women (mean age = 51 years) received information about bone density screening and osteoporosis. They were then randomly allocated to 1 of 4 groups and were encouraged to focus on positive issues about bone density screening (positive group), on negative issues (negative group), on both positive and negative issues (all-focusing group), or on issues relating to the common cold (control group). Women were asked to rate how likely they would be to opt for bone density screening if they saw it available. After being informed that they could have bone density screening, actual uptake was assessed. It was found that the issues on which individuals focused significantly influenced their rate likelihood of opting for the scan. Rated likelihood of testing was significantly associated with whether individuals actually did opt for testing when it was subsequently offered to them.

Obsessive-compulsive disorder, anxiety disorders, and self-esteem: an exploratory study

In a preliminary investigation of the link between self-esteem and obsessional problems, patients with OCD were compared with people suffering from other anxiety disorders and non-anxious controls. A questionnaire was devised which allowed the reliable coding of open ended responses focussed on issues surrounding self-worth; standardized measures of self-esteem and clinical symptomatology were also administered. Results indicated that both clinical groups differed significantly from non-clinical controls on generalized self-esteem assessments. There was some evidence of OCD specific effects; obsessionals were more likely than anxious controls to link their self-worth to other people and their relationships. They also regarded the possibility of causing harm as likely to result in other people making extreme negative and critical judgements of them; the other groups expected the responses of others towards them to be more lenient. The implications for future research and for treatment of OCD are discussed.

The prospect of predictive testing for personal risk: attitudes and decision making

As predictive tests for medical problems such as genetic disorders become more widely available, it becomes increasingly important to understand the processes involved in the decision whether or not to seek testing. This study investigates the decision to pursue the possibility of testing. Individuals (one group who had already contemplated the possibility of predictive testing and one group who had not) were asked to consider predictive testing for several diseases. They rated the likelihood of opting for testing and specified the reasons which they believed had affected their decision. The ratio of the numbers of reasons stated for testing and the numbers of reasons stated against testing was a good predictor of the stated likelihood of testing, particularly when the reasons were weighted by utility (importance). Those who had previously contemplated testing specified more emotional reasons. It is proposed that the decision process is internally logical although it may seem illogical to others due to there being idiosyncratic premises (or reasons) upon which the decision is based. It is concluded that the Utility Theory is a useful basis for describing how people make decisions related to predictive testing; modifications of the theory are proposed.

Predictive genetic testing: psychological factors

Advances in medical technology such as those linked to the human genome project are increasing the potential for predictive testing for a wide range of health threats. There have not been comparable advances in understanding of the psychological factors involved in such testing. These factors and issues relating to them are examined, and it is suggested that a cognitive-behavioral approach to the understanding and management of adverse reactions to testing is likely to be particularly fruitful. The use of such an approach should result in the development of effective pre- and posttest interventions to prevent, minimize, and manage distress associated with screening.

Mammography: role of the occupational health nurse

1. According to ACS and NCl guidelines, women should begin screening mammography with a baseline film between 35 and 39 years of age. She should then maintain routine mammography screening per the guidelines. 2. Twenty-five percent of women diagnosed with breast cancer have known risk factors. 3. Further investigation of the effectiveness of worksite mammography and mobile mammography vans is needed. 4. Occupational health nurses are in an optimal position to increase the level of current mammography usage.
