Effects of physical activity on the fatigue and psychologic status of cancer patients during chemotherapy.

BACKGROUND: Fatigue is a common and often severe problem in cancer patients undergoing chemotherapy. The authors postulated that physical activity training can reduce the intensity of fatigue in this group of patients. METHODS: A group of cancer patients receiving high dose chemotherapy followed by autologous peripheral blood stem cell transplantation (training group; n = 27) followed an exercise program during hospitalization. The program was comprised of biking on an ergometer in the supine position following an interval training pattern for 30 minutes daily. Patients in the control group (n = 32) did not train. Psychologic distress was assessed at hospital admission and discharge with the Profile of Mood States and Symptom Check List 90. RESULTS: By the time of hospital discharge, fatigue and somatic complaints had increased significantly in the control group (P for both < 0.01) but not in the training group. Furthermore, by the time of hospital discharge, the training group had a significant improvement in several scores of psychologic distress (obsessive-compulsive traits, fear, interpersonal sensitivity, and phobic anxiety) (P value for all scores < 0.05); this outcome was not observed in the control group. CONCLUSIONS: The current study found that aerobic exercise can reduce fatigue and improve psychologic distress in cancer patients undergoing chemotherapy.

[Quality of life. Construct validation and the development of a modular system].

The construct Quality of Life (QoL) is investigated by metaanalysis of eight (inter)nationally validated questionnaires in a multicenter study. Data have been collected in a mentally healthy (n = 479), a depressed (n = 171) and a schizophrenic (n = 139) sample. Conventional psychometric criteria and a facet analytical methodology have been applied. The resulting questionnaire "Modular System for Quality of Life" (MSQoL) consists of a core module with 47 items (one "G-factor" and six subdimensions), which is sufficiently valid for all three samples. Additionally, there are four specific modules (demography, family, partnership, profession). No specific modules can be identified for the psychopathological subgroups. The validated radex structure for subjective QoL offers the opportunity for a cumulative research design and for adaptations to the actual setting.

The concept of "sense of coherence" and the development of posttraumatic stress disorder in traffic accident victims.

According to the "sense of coherence" concept, those subjects who can give meaning to a traumatic event can comprehend what has happened and have a sense of manageability of the sequelae, are able to cope better with the traumatic event itself. In the present study, this concept was applied to traffic accident victims. Severely injured traffic accident victims were assessed a few days after the accident and at 6-month follow-up. At follow-up, patients filled in the 29-item version of the Sense of Coherence (SOC) self-rating scale. The results show that the SOC total score correlated negatively with the development of: (i) posttraumatic psychopathology; (ii) psychological disorders (i.e., posttraumatic stress disorder after the accident); and (iii) anxious cognitions. The personality trait of neuroticism correlated negatively and extraversion and frustration tolerance correlated positively with SOC total score. Previous hypotheses are supported by our findings.

[Inpatient treatment of depressed patents. Conceptual considerations and results of a pilot project for quality assurance in Baden-Württemberg].

Quality-assurance activities will become more important in psychiatry during the next few years. In relation to other medical disciplines, some special aspects concerning structure, process and outcome quality as well as practical realization and methodologic aspects must be considered. These specific issues were the focus of a study dealing with the treatment of depressed inpatients. The experiences and results as well as considerations concerning future quality-assurance projects are discussed.

[Follow-up assessment of mood in depressive patients].

Three short, respectively promising self-rating scales used for the assessment of emotional states, especially depression, were examined: a visual analogue scale with only five items, a short version of the so-called "adjectives list" and a differentiated scale for recording current emotions, possible susceptibility to them and the ability to express them. We checked statistical parameters of item analysis, reliability, validity and time course measurement. This study was carried out with depressive inpatients (n = 35) at the time of admission and 4 weeks later in beginning remission. All three scales proved to be reliable (Cronbach-alpha between 0.48 and 0.97) and partially very valid instruments (concurrent validity between 0.04 and 0.87). In order to improve the documentation of a beginning response to therapeutic efforts, separate recordings of depressive subsyndromes such as "impetus" or "positive emotionality" seem to be quite promising approaches.

Prediction of posttraumatic stress disorder by immediate reactions to trauma: a prospective study in road traffic accident victims.

Road traffic accidents often cause serious physical and psychological sequelae. Specialists of various medical faculties are involved in the treatment of accident victims. Little is known about the factors which might predict psychiatric disorders, e.g. Posttraumatic Stress Disorder (PTSD) after accidents and how psychological problems influence physical treatment. In a prospective study 179 unselected, consecutively admitted road traffic accident victims were assessed a few days after the accident for psychiatric diagnoses, severity of injury and psychopathology. All were inpatients and had to be treated for bone fractures. At 6-months follow-up assessment 152 (85%) of the patients were interviewed again. Of the patients, 18.4% fulfilled the criteria for Posttraumatic Stress Disorder (DSM-III-R) within 6 months after the accident. Patients who developed PTSD were injured more severely and showed more symptoms of anxiety, depression and PTSD a few days after the accident than patients with no psychiatric diagnosis. Patients with PTSD stayed significantly longer in the hospital than the other patients. Multiple regression analysis revealed that the length of hospitalization was due mainly to a diversity of factors such as severity of injury, severity of accident, premorbid personality and psychopathology. Posttraumatic stress disorder is common after road traffic accidents. Patients with PTSD at follow-up can be identified by findings from early assessment. Untreated psychological sequelae such as PTSD cause longer hospitalization and therefore more costs than in non-PTSD patients.

Adaptation and psychometric properties of the German version of the Dissociative Experience Scale.

We introduce the 'Fragebogen zu Dissoziativen Symptomen' (FDS), a German adaptation of the Dissociative Experience Scale (DES) which was developed to screen for dissociation within an ICD-10 framework. In addition to the original 28 DES items, the FDS contains 16 items covering dissociative phenomena included in the ICD-10, particularly pseudoneurological conversion symptoms. The psychometric properties of the FDS were studied in 927 clinical and nonclinical subjects from different diagnostic groups and compared to results of American studies. The scale had good test-retest reliability of .88, high internal consistency (split-half = .90, Cronbach's alpha = .94) and good construct validity. These results indicate that the FDS may be a valuable screen for dissociative psychopathology in German-speaking countries.

Psychopathological assessment and diagnosis. A study of specificity of single symptoms.

The importance of single symptoms in the diagnostic process has not been adequately studied, mainly because of the complexity of the information involved. The aim of the present study is to investigate the interconnection between psychopathological assessment and diagnostic classification, with the aid of a nonparametric, inductive pattern recognition method. Using the concept of inductive logic and a theory of inductive knowledge acquisition, a model has been developed to describe psychopathological assessment and diagnostic classification. Based on a comprehensive psychopathological assessment in 837 patients with 14 different diagnoses, classification values were calculated for specific symptoms in different diagnostic groups. Furthermore, nonparametric statistical procedures have advantages over discriminant analytic approaches: more information is utilized in differentiating the groups and differentiations can be made between more groups, whereby the rate of correctly classified cases is comparable with discriminant analytic approaches. The pattern recognition method appears to illustrate the multidimensional, medical decision-making in a comprehensible way.

[Children of mentally ill parents. A study of problem awareness in clinical routine practice].

The risk of developing clinically relevant psychiatric disorders in the lifetime course is significantly greater among children of mentally ill parents. A child-adapted programme of information concerning the nature and symptomatology of parental illness is considered to be an important preventive factor, and lies within the domain of the psychiatrist's or therapist's responsibilities. During the developmental phase of a prevention project at Freiburg University's Department of Psychiatry and Psychotherapy, both clinical practice and the level of problem awareness among patients and the therapists were evaluated. Over a period of one year, consecutive interviews involving 114 patients with children under 18 years of age, as well as their respective therapists, were conducted. The results showed that: scarcely any exchanges between children and therapists took place; the extent to which children are informed about parental illness must be considered as small; a high percentage of such children are already evaluated by their parents as disturbed, and the pressing need for support exists.

[Questionnaire on dissociative symptoms. German adaptation, reliability and validity of the American Dissociative Experience Scale (DES)].

The "Fragebogen zu dissoziativen Symptomen (FDS)" represents the authorised German translation and adaptation of the "Dissociative Experience Scale" (DES; Bernstein and Putnam 1986). The original scale comprises 28 items covering dissociative experiences with regard to memory, identity, awareness and cognition according to DSM-III-R and DSM-IV. For the German version, 16 items were added to cover dissociative phenomena according to ICD-10, mainly pseudoneurological conversion symptoms. Reliability and validity of the German version were studied in a total sample of 813 persons and were compared to the results of the original version. Test-retest reliability of the FDS was rtt = 0.88 and Cronbach's consistency coefficient was alpha = 0.93, which is comparable to the results of the DES. The instrument differentiates between different samples (healthy control subjects, students, unselected neurological and psychiatric inpatients, neurological and psychiatric patients with a dissociative disorder and schizophrenics). The FDS is an easily applicable, reliable and valid measure to quantify dissociative experiences.

Correlation between physical performance and fatigue in cancer patients.

BACKGROUND: Fatigue and a reduction in physical ability are common and often severe problems of cancer patients regardless of disease stage and modality of treatment. However, while physical performance can be assessed objectively with laboratory tests, fatigue is a subjective phenomenon whose perception is influenced by past experience and expectations for the future. PATIENTS AND METHODS: To evaluate the correlation between fatigue and physical impairment, we assessed maximal physical performance with a treadmill test, and mental state with two questionnaires, the Profile of Mood States (POMS) and the Symptom Check List (SCL-90-R), in a successive series of 78 cancer patients with solid tumors or hematological malignancies. RESULTS: A weak association between fatigue and maximal physical performance was found (r = -0.30; P < 0.01). However, intensity of fatigue showed a strong correlation with several indicators of psychological distress such as depression (r = 0.68), somatization (r = 0.64) and anxiety (r = 0.63; P for all < 0.001). Furthermore, patients with lower levels of physical performance had significantly higher scores for depression (P = 0.005), somatization (P = 0.03) and anxiety (P = 0.08), and significantly lower scores for vigor (P = 0.05) than their counterparts whose physical performance was higher. CONCLUSIONS: We conclude that fatigue in cancer patients may be related to mood disturbance but appears to be independent of physical performance. Moreover, low physical performance can be viewed as an independent predictor of mental distress in cancer patients.

Serum concentrations of thyroid hormones in patients with nonseasonal affective disorders during treatment with bright and dim light.

Serum concentrations of thyroxine (T4), triiodothyronine (T3), and thyrotropine were measured in 34 patients with nonseasonal affective disorders before and after 1 week of light treatment. Nineteen of these patients received bright white light (2500 lx) and 15 dim red light (50 lx) for 2 hours daily in the mornings over a 1-week period. Slight but significant reductions in the rating scores for the depressive symptomatology were found for both the bright-and dim-light groups, but there were no significant differences between the two groups. The improvement is thus most likely a placebo effect. Surprisingly, the small changes in the severity of the depressive symptoms in the group as a whole were significantly correlated to the changes in the serum levels of T4 during the weeks of bright- and dim-light treatment, respectively. The more a patient improved, the further his or her T4 level fell and vice versa. The fluctuations in the concentrations of T4 during light treatment were significantly greater in the depressed patients than in a group of 12 healthy controls who also received bright or dim light, whereas the changes in T3 were significantly smaller than those of the healthy controls. The pronounced fluctuations in T4 levels were probably not secondary to changes in mood. Rather, they are likely to reflect changes in tissue (intracellular) metabolism of T4, which may be involved in the mechanisms underlying the fluctuations in mood in these patients.

Schizophrenia, schizotypal and delusional disorders (F2). Results from the ICD-10 field trial of the Diagnostic Criteria for Research in German-speaking countries.

The results of the ICD-10 field trial of the Diagnostic Criteria for Research in German-speaking countries concerning section F2, "Schizophrenia, schizotypal and delusional disorders', are presented. From a total of 39 cases (written case reports and video tapes) 5 met the criteria for schizophrenia (F20) with 201 ratings. The majority of clinicians rated the ease of diagnosis, confidence of diagnosis, and goodness of fit positive. The reliability of the 2-character diagnoses was excellent (F2; kappa = 0.88), as was the case for the category schizophrenia (F20; kappa = 0.89) and was higher than in the comparable study concerning the Clinical Diagnostic Guidelines.

Instruments in the assessment of psychosomatic and neurotic disorders.

The introduction of DSM-III/DSM-III-R and ICD-10 implies fundamental innovations to the diagnostic process. The changes relate both to formal aspects (e.g. symptom and time-related criteria) and to content (e.g. the abandonment of the concept of neurosis). Additionally, specific assessment instruments are introduced. However, other aspects important for the description and treatment of patients easily become neglected when concentrating on a system of diagnoses which aim at the classification of patients by groups of disorders. The present article will present instruments which make it possible to do justice to both points of view.

[Suicidal behavior of depressed patients at inpatient admission].

Early recognition of suicidal behavior is of extreme importance for avoidance of this cause of death. The risk of suicide attempts is particularly high in psychiatric illness, and among hospital in-patients especially in those with depression. Thus, the risk of suicide should be estimated in the first interview after admission to a psychiatric hospital. Our study analysed the routine documentation of such interviews on admission to the Psychiatrische Klinik der Freien Universität in Berlin: 41% of all depressive patients were suicidal. Suicidal and non-suicidal depressive patients could be differentiated by the following traits: suicidal patients were younger, had been younger at the initial onset of depressive illness, had made more suicide attempts in the past, and had a greater number of relatives who had committed suicide or made suicide attempts. They were more often single or divorced, and had fewer children of their own. Their psychopathology was characterized by a more strongly developed syndrome of depression, hostility and apathy. These findings point to a pattern of characteristics that are linked with suicidal behavior, which can be used to estimate the risk of suicide right at the beginning of a stay in hospital.
