What I think and feel: a revised measure of children's manifest anxiety

The 1956 adaptation for children of Taylor's Manifest Anxiety Scale, the Children's Manifest Anxiety Scale, was revised to meet current psychometric standards. A 73-item revision draft was administered to 329 school children from grades 1 to 12. Based on item-analysis criteria for rbis greater than or equal to .4 and .30 less than or equal to p less than or equal to .70, 28 anxiety items were retained along with 9 of the original 11 Lie scale items. A cross-validation sample of 167 children from grades 2, 5, 9, 10, and 11 produced a KR20 reliability estimate of .85. Anxiety scores did not differ across grade or race. Females scored significantly higher than males. For the Lie scale, significant differences appeared by grade and race. No sex differences were obtained on the Lie scale. The resulting scale appears useful for children in grades 1 to 12 and may aid in future studies of anxiety as well as assisting the clinician in the understanding of individual children.

Developing a cancer-specific geriatric assessment: a feasibility study

BACKGROUND

As the U.S. population ages, there is an emerging need to characterize the "functional age" of older patients with cancer to tailor treatment decisions and stratify outcomes based on factors other than chronologic age. The goals of the current study were to develop a brief, but comprehensive, primarily self-administered cancer-specific geriatric assessment measure and to determine its feasibility as measured by 1) the percentage of patients able to complete the measure on their own, 2) the length of time to complete, and 3) patient satisfaction with the measure.

METHODS

The geriatric and oncology literature was reviewed to choose validated measures of geriatric assessment across the following domains: functional status, comorbidity, cognition, psychological status, social functioning and support, and nutritional status. Criteria applied to geriatric assessment measurements included reliability, validity, brevity, and ability to self-administer. The measure was administered to patients with breast carcinoma, lung carcinoma, colorectal carcinoma, or lymphoma who were fluent in English and receiving chemotherapy at Memorial Sloan-Kettering Cancer Center (New York, NY) or the University of Chicago (Chicago, IL).

RESULTS

The instrument was completed by 43 patients (mean age, 74 yrs; range, 65-87 yrs). The majority had AJCC Stage IV disease (68%). The mean time to completion of the assessment was 27 minutes (range, 8-45 mins). Most patients were able to complete the self-administered portion of the assessment without assistance (78%) and were satisfied with the questionnaire length (90%). There was no association noted between age (P = 0.56) or educational level (P = 0.99) and the ability to complete the assessment without assistance.

CONCLUSIONS

In this cohort, this brief but comprehensive geriatric assessment could be completed by the majority of patients without assistance. Prospective trials of its generalizability, reliability, and validity are justified.

Application of the multidimensional fatigue inventory (MFI-20) in cancer patients receiving radiotherapy

In this paper the psychometric properties of the multidimensional fatigue inventory (MFI-20) are established further in cancer patients. The MFI is a 20-item self-report instrument designed to measure fatigue. It covers the following dimensions: general fatigue, physical fatigue, reduced activity, reduced motivation and mental fatigue. The instrument was used in a Dutch and Scottish sample of cancer patients receiving radiotherapy. The dimensional structure was assessed using confirmatory factor analyses (Lisrel's unweighted least-squares method). The hypothesised five-factor model appeared to fit the data in both samples (adjusted goodness of fit; AGFI: 0.97 and 0.98). Internal consistency of the separate scales was good in both the Dutch and Scottish samples with Cronbach's alpha coefficients ranging from 0.79 to 0.93. Construct validity was assessed by correlating the MFI-20 to activities of daily living, anxiety and depression. Significant relations were assumed. Convergent validity was investigated by correlating the MFI scales with a visual analogue scale measuring fatigue and with a fatigue-scale derived from the Rotterdam Symptom Checklist. Results support the validity of the MFI-20. The highly similar results in the Dutch and Scottish sample suggest that the portrayal of fatigue using the MFI-20 is quite robust.

Symptoms of posttraumatic stress in young adult survivors of childhood cancer

PURPOSE

This study assessed the prevalence of posttraumatic stress symptoms in young adult survivors of childhood cancer and the association of posttraumatic stress with anxiety, adjustment, perceptions of illness and treatment, and medical data extracted from oncology records.

PATIENTS AND METHODS

Seventy-eight young adults (ages 18 to 40 years) who had been treated for childhood cancer completed questionnaires and psychiatric interviews assessing posttraumatic stress, anxiety, perceptions of their illness and treatment, and symptoms of psychologic distress. Data on treatment intensity and severity of medical late effects were collected via chart review.

RESULTS

Of the patient sample, 20.5% met American Psychiatric Association Diagnostic and Statistical Manual criteria for posttraumatic stress disorder (PTSD) at some point since the end of their treatment. Clinically significant levels of intrusive (9%) and avoidant (16.7%) symptoms were reported. Participants also reported elevated state and trait anxiety. Participants with PTSD reported higher perceived current life threat, more intense treatment histories, and higher (and clinically significant) levels of psychologic distress than those who did not have PTSD.

CONCLUSION

One-fifth of this sample of young adult survivors of childhood cancer met criteria for a diagnosis of PTSD, with clinically significant symptoms of intrusion and avoidance reported. As in other samples, PTSD in young adult survivors was associated with anxiety and other psychologic distress. Survivors' perceptions of treatment and its effects were more highly associated with posttraumatic stress than were more objective medical data. The data suggest that cancer-related posttraumatic stress may emerge in young adulthood and may affect the achievement of developmental milestones and orientation toward health care.

Pervasive emotion recognition deficit common to alexithymia and the repressive coping style

OBJECTIVE

Previous research has demonstrated a deficit in the ability to recognize emotions in alexithymic individuals. The repressive coping style is thought to preferentially impair the detection of unpleasant compared with pleasant emotions, and the degree of deficit is typically thought to be less severe than in alexithymia. We compared emotion recognition ability in both individuals with alexithymia and those with the repressive coping style.

METHODS

Three hundred seventy-nine subjects completed the 20-item Toronto Alexithymia Scale, the Levels of Emotional Awareness Scale, the Marlowe-Crowne Scale (a measure of repressive defensiveness), the Bendig Short Form of the Taylor Manifest Anxiety Scale, and the Perception of Affect Task. The Perception of Affect Task consists of four 35-item emotion recognition subtasks: matching sentences and words, faces and words, sentences and faces, and faces and photographs of scenes. The stimuli in each subtask consist of seven emotions (happiness, sadness, anger, fear, disgust, surprise, and neutral) depicted five times each. Recognition accuracy results were collapsed across subtasks within each emotion category.

RESULTS

Highly alexithymic subjects (for all, p<.01) and those with low emotional awareness (for all, p<.001) were consistently less accurate in emotion recognition in all seven categories. Highly defensive subjects (including repressors) were less accurate in the detection of anger, sadness, fear, and happiness (for all, p<.05). Furthermore, scores on the Levels of Emotional Awareness Scale accounted for significantly more variance in performance on the Perception of Affect Task than scores on the Marlowe-Crowne Scale (p<.01).

CONCLUSIONS

The results indicate that alexithymia and the repressive coping style are each associated with impairments in the recognition of both pleasant and unpleasant emotions and that the two styles of emotional self-regulation differ more in the magnitude than in the quality of these impairments.

Treating anxiety disorders in children with high functioning autism spectrum disorders: a controlled trial

A family-based, cognitive behavioural treatment for anxiety in 47 children with comorbid anxiety disorders and High Functioning Autism Spectrum Disorder (HFA) was evaluated. Treatment involved 12 weekly group sessions and was compared with a waiting list condition. Changes between pre- and post-treatment were examined using clinical interviews as well as child-, parent- and teacher-report measures. Following treatment, 71.4% of the treated participants no longer fulfilled diagnostic criteria for an anxiety disorder. Comparisons between the two conditions indicated significant reductions in anxiety symptoms as measured by self-report, parent report and teacher report. Discussion focuses on the implications for the use of cognitive behaviour therapy with HFA children, for theory of mind research and for further research on the treatment components.

Factor structure and construct validity of "what I think and feel": The Revised Children's Manifest Anxiety Scale

Responses to the Revised-CMAS of 329 children from grades 1 through 12 were factor analyzed. Consistent with current multidimensional theories of anxiety, three primary anxiety factors emerged, supporting the construct validity of the new scale. Implications for interpretation of the revised scale are discussed.

Prevention of anxiety symptoms in primary school children: preliminary results from a universal school-based trial

Preliminary data are presented on the effectiveness of a universal school-based intervention for the prevention of anxiety symptoms in primary school children. A sample of 489 children (aged 10-12 years) were assigned to one of three intervention conditions: a psychologist-led preventive intervention, a teacher-led preventive intervention, or a usual care (standard curriculum) with monitoring condition. The intervention offered was the Friends for Children programme, a 12-session cognitive-behavioural intervention, originally based upon Kendall's (1994) Coping Cat programme. Participants in both intervention conditions reported fewer symptoms of anxiety at post-intervention than participants in the usual care condition. These preliminary results suggest that universal programmes for childhood anxiety are promising intervention strategies that can be successfully delivered to a school-based population and integrated into the classroom curriculum.

Web-based cognitive behavior therapy: analysis of site usage and changes in depression and anxiety scores

BACKGROUND

Cognitive behavior therapy is well recognized as an effective treatment and prevention for depression when delivered face-to-face, via self-help books (bibliotherapy), and through computer administration. The public health impact of cognitive behavior therapy has been limited by cost and the lack of trained practitioners. We have developed a free Internet-based cognitive behavior therapy intervention (MoodGYM, http://moodgym.anu.edu.au) designed to treat and prevent depression in young people, available to all Internet users, and targeted to those who may have no formal contact with professional help services.

OBJECTIVE

To document site usage, visitor characteristics, and changes in depression and anxiety symptoms among users of MoodGYM, a Web site delivering a cognitive-behavioral-based preventive intervention to the general public.

METHODS

All visitors to the MoodGYM site over about 6 months were investigated, including 2909 registrants of whom 1503 had completed at least one online assessment. Outcomes for 71 university students enrolled in an Abnormal Psychology course who visited the site for educational training were included and examined separately. The main outcome measures were (1) site-usage measures including number of sessions, hits and average time on the server, and number of page views; (2) visitor characteristics including age, gender, and initial Goldberg self-report anxiety and depression scores; and (3) symptom change measures based on Goldberg anxiety and depression scores recorded on up to 5 separate occasions.

RESULTS

Over the first almost-6-month period of operation, the server recorded 817284 hits and 17646 separate sessions. Approximately 20% of sessions lasted more than 16 minutes. Registrants who completed at least one assessment reported initial symptoms of depression and anxiety that exceeded those found in population-based surveys and those characterizing a sample of University students. For the Web-based population, both anxiety and depression scores decreased significantly as individuals progressed through the modules. CONCLUSIONS Web sites are a practical and promising means of delivering cognitive behavioral interventions for preventing depression and anxiety to the general public. However, randomized controlled trials are required to establish the effectiveness of these interventions.

The memorial anxiety scale for prostate cancer: validation of a new scale to measure anxiety in men with with prostate cancer

BACKGROUND

The psychological difficulties facing men with prostate cancer are acknowledged widely, yet identifying men who may benefit from mental health treatment has proven to be a challenging task. The authors developed the Memorial Anxiety Scale for Prostate Cancer (MAX-PC) to facilitate the identification and assessment of men with prostate cancer-related anxiety. This scale consists of three subscales that measure general prostate cancer anxiety, anxiety related to prostate specific antigen (PSA) levels in particular, and fear of recurrence.

METHODS

Ambulatory men with prostate cancer (n = 385 patients) were recruited from clinics throughout the United States. Prior to routine PSA tests, participants completed a baseline assessment packet that included the Hospital Anxiety and Depression Scale; the Distress Thermometer; the Functional Assessment of Cancer Therapy Scale, Prostate Module; and measures of role functioning, sleep, and urinary functioning. PSA values from the last three tests also were collected. Follow-up evaluation was completed within 2 weeks after patients learned of their PSA test result using a subset of these scales.

RESULTS

Analysis of the MAX-PC revealed a high degree of internal consistency and test-retest reliability for the total score and for the three subscales, although reliability was somewhat weaker for the PSA Anxiety Scale. Concurrent validity was demonstrated by correlations between the MAX-PC and measures of anxiety. Overall changes in PSA levels were correlated only modestly with changes in MAX-PC scores (correlation coefficient, 0.13; P = 0.02).

CONCLUSIONS

The MAX-PC appears to be a valid and reliable measure of anxiety in men with prostate cancer receiving ambulatory care.

Age of onset of dental anxiety

Little attention has been given to the issue of the age of onset of dental anxiety, even though it may have a bearing on the origins of this type of fear. This study aimed to identify the age of onset of dental anxiety and to identify differences by age of onset with respect to potential etiological factors, such as negative dental experiences, family history of dental anxiety, and general psychological states. Data were collected by means of two mail surveys of a random sample of the adult population. Of 1420 subjects returning questionnaires, 16.4% were dentally anxious. Half, 50.9%, reported onset in childhood, 22.0% in adolescence, and 27.1% in adulthood. Logistic regression analyses indicated that negative dental experiences were predictive of dental fear regardless of age of onset. A family history of dental anxiety was predictive of child onset only. Adolescent-onset subjects were characterized by trait anxiety and adult-onset subjects by multiple severe fears and symptoms indicative of psychiatric problems. The three groups were similar in terms of their physiological, cognitive, and behavioral responses to dental treatment. However, adolescent- and adult-onset subjects were more hostile toward and less trusting of dentists. These results indicate that child-onset subjects were more likely to fall into the exogenous etiological category suggested by Weiner and Sheehan (1990), while adult-onset subjects were more likely to fall into the endogenous category.

Four dimensions of fear of dental injections

In 1995, students and staff at the University of Washington were surveyed regarding avoidance of dental care and fear of dental injections. More than 25 percent of adults surveyed expressed at least one clinically significant fear of injections. Almost one in 20 respondents indicated avoiding, cancelling or not appearing for dental appointments because of fear of dental injections. Fear of dental injections consists of four dimensions. General fear of dental injections including pain of injection and of bodily injury from injection are the two most common dimensions of dental injection fear. Many people also express fears of acquired disease. Fear related to local anesthetic (such as side effects, inadequate anesthesia) is less frequent. Some respondents have fears that must be categorized using more than one of these dimensions. Understanding the nature of a patient's fear of injection may suggest strategies to address his or her concerns.

Stress management improves long-term glycemic control in type 2 diabetes

OBJECTIVE

There is conflicting evidence regarding the utility of stress management training in the treatment of diabetes. The few studies that have shown a therapeutic effect of stress management have used time-intensive individual therapy. Unfortunately, widespread use of such interventions is not practical. The aim of the present investigation is to determine whether a cost-effective, group-based stress management training program can improve glucose metabolism in patients with type 2 diabetes and to determine whether a particular subset of patients is more likely to get positive results.

RESEARCH DESIGN AND METHODS

Patients with type 2 diabetes were randomized to undergo a five-session group diabetes education program with or without stress management training. Participants (n = 108) were followed for 1 year, during which HbA(1c) tests and questionnaires assessing perceived stress, anxiety, and psychological health were administered at regular intervals to evaluate treatment effects.

RESULTS

Stress management training was associated with a small (0.5%) but significant reduction in HbA(1c). Compliance with the treatment regimen decreased over time but was similar to that seen in patients receiving stress management for other reasons in the clinic. Trait anxiety (a measure of stable individual differences in anxiety proneness) did not predict response to treatment, showing that highly anxious patients did not derive more benefit from training.

CONCLUSIONS

The current results indicate that a cost-effective, group stress management program in a "real-world" setting can result in clinically significant benefits for patients with type 2 diabetes.

Cognitive functioning and psychiatric symptomatology in patients with chronic hepatitis C

Hepatitis C virus (HCV) infection is a major public-health-care problem, with over 170 million infected worldwide. Patients with chronic HCV infection often complain of various cognitive problems as well as symptoms of depression, anxiety, and fatigue. Relatively little is known, however, about the specific cognitive deficits that are common among HCV patients, and the influence of psychiatric symptomatology on cognitive functioning. In the current study of 21 chronically infected HCV patients, we assessed subjective cognitive dysfunction, depression, anxiety, and fatigue and compared these symptom areas to cognitive tests assessing visuoconstruction, learning, memory, visual attention, psychomotor speed, and mental flexibility. Results revealed that cognitive impairment ranged from 9% of patients on a visuoconstruction task to 38% of patients on a measure of complex attention, visual scanning and tracking, and psychomotor speed, and greater HCV disease severity as indicated by liver fibrosis was associated with greater cognitive dysfunction. Objective cognitive impairment was not related to subjective cognitive complaints or psychiatric symptomatology. These findings suggest that a significant portion of patients with chronic HCV experience cognitive difficulties that may interfere with activities of daily living and quality of life. Future research using cognitive measures with HCV-infected patients may assist researchers in identifying if there is a direct effect of HCV infection on the brain and which patients may be more likely to progress to cirrhosis and hepatic encephalopathy.

Sleep pathophysiology in posttraumatic stress disorder and idiopathic nightmare sufferers

BACKGROUND

Nightmares are common in posttraumatic stress disorder (PTSD), but they also frequently occur in idiopathic form. Findings associated with sleep disturbances in these two groups have been inconsistent, and sparse for idiopathic nightmares. The aim of the present study was to investigate whether sleep anomalies in PTSD sufferers with frequent nightmares (P-NM) differ from those observed in non-PTSD, idiopathic nightmare (I-NM) sufferers and healthy individuals.

METHODS

Sleep measures were obtained from nine P-NM sufferers, 11 I-NM sufferers, and 13 healthy control subjects. All participants slept in the laboratory for two consecutive nights where electroencephalogram, electro-oculogram, chin and leg electromyogram, electrocardiogram, and respiration were recorded continuously.

RESULTS

Posttraumatic nightmare sufferers had significantly more nocturnal awakenings than did I-NM sufferers and control subjects. Elevated indices of periodic leg movements (PLMs) during rapid eye movement (REM) and non-REM sleep characterized both P-NM and I-NM sufferers.

CONCLUSIONS

Posttraumatic nightmare sufferers exhibit more nocturnal awakenings than do I-NM sufferers and control subjects, which supports the hypothesis of hyperarousal in sleep in PTSD sufferers; however, elevated PLM indices in both P-NM and I-NM sufferers suggest that PLMs may not be a marker of hyperarousal in sleep of PTSD sufferers. Rather, PLMs may be a correlate of processes contributing to intense negative dreaming.

Prevalence and characteristics of dental anxiety in Danish adults

Prevalence, characteristics and consequences of dental anxiety in a randomly selected sample of 645 Danish adults were explored in telephone interviews. Participation rate was 88%. Demographics, fear of specific procedures, negative dentist contacts, general fear tendency, treatment utilization and perceived oral conditions were explored by level of dental anxiety using a modified Dental Anxiety Scale (DAS). A Seattle fear survey item and a summary item from the Dental Fear Survey (DFS) were also included for fear description comparisons. Correlation between these indices (DAS-DFS: rs = 0.72; DAS-Seattle item: rs = 0.68) aided semantic validation of DAS anxiety intensity levels. Extreme dental anxiety (DAS > or = 15) was found in 4.2% of the sample and 6% reported moderate anxiety (DAS scores 14-12). Bivariate (B) and logistic regression (L) odds ratios (OR) showed that high dental anxiety was associated with gender, education and income, but not with age. Extreme dental anxiety for dentate subjects was characterized by fear of drilling (ORL = 38.7), negative dentist contacts (ORL = 9.3), general fear tendency (ORL = 3.4), avoidance of treatment (ORL = 16.8) and increased oral symptoms (ORB = 4.4). Moderate dental anxiety was also related to drilling (ORL = 22.3), but with less avoidance due to anxiety (ORL = 6.8) compared with low fear subjects.

Further evidence for the reliability and validity of the Modified Dental Anxiety Scale

AIM

To gain further evidence of the psychometric properties of the Modified Dental Anxiety Scale.

SETTING

Dental admission clinics.

DESIGN

Consecutive sampling, cross-sectional survey.

PARTICIPANTS

Patients (n = 800) in four cities (Belfast, Northern Ireland; Helsinki, Finland; Jyväskylä, Finland and Dubai, UAE).

METHODS

Questionnaire booklet handed to patients, attending clinics, for completion following an invitation by the researcher to be included in the study.

MEASURES

Modified Dental Anxiety Scale (MDAS), together with further questions concerning dental attendance and nervousness about dental procedures.

RESULTS

Overall 9.3 per cent of patients indicated high dental anxiety. MDAS showed high levels of internal consistency, and good construct validity. The relationship of dental anxiety with age was similar to previous reports and showed lowered anxiety levels in older patients.

CONCLUSION

Data from three countries has supported the psychometric properties of this modified and brief dental anxiety scale.

A further review of the results of sterotactic subcaudate tractotomy

There is accumulating evidence of the clinical effectiveness of selective stereotactic psychosurgery in some severely disabled psychiatric patients who have not responded to other forms of treatment (Ström-Olsen and Carlisle, 1971; Bridges, Göktepe and Maratos, 1973; Kelly et al., 1973). The risks of adverse effects resulting from operation are now small, and their significance is further diminished when related to the distress over long periods of those patients who are suitable for psychosurgery. The criteria for selection have been considered by Bridges and Bartlett (1973).

The impact of dental anxiety on daily living

AIM

To explore the impact of dental anxiety on daily living.

METHOD

Twenty people attending a dental sedation clinic completed the Modified Dental Anxiety Scale, and were interviewed privately using a reflexive, in-depth technique. All interviews were audio-tape recorded and transcribed. The transcripts were analysed to identify the impact of dental anxiety upon the participants' daily lives. Twenty-five per cent of the qualitative data was reviewed by an independent researcher to ensure the reliability of the analysis.

RESULTS

The mean age of participants was 41 years (range 23 to 60). The mean MDAS score was 21.5 (range 14 to 25). Five main impacts of dental anxiety were identified: physiological; cognitive; behavioural; health; and social. Subsumed under these broad categories were: the fright response; a vast array of negative thoughts, feelings and fears; avoidance behaviour and behaviours related to eating, oral hygiene, and self-medication; and other manifestations of anxiety in the dental environment including muscular tension, crying and aggression were all identified. Dental anxiety was also found to disturb sleep and to have a profound affect socially, interfering with work and personal relationships.

CONCLUSION

The impact that dental anxiety can have on people's lives is wide-ranging and dynamic.
