Comparing aerobic with nonaerobic forms of exercise in the treatment of clinical depression: A randomized trial

We compared aerobic with nonaerobic forms of exercise in the treatment of clinical depression. Ninety-nine inpatients, who met the DMS-III-R criteria for major depression, dysthymic disorder, or depressive disorder not otherwise specified (NOS), took part in the study. They were randomly assigned to two different physical training conditions, aerobic and nonaerobic. In both conditions, one hour of training was performed three times a week for a period of 8 weeks. There was a significant increase in maximum oxygen uptake (VO2 max) in the aerobic group; there was no change in the nonaerobic group regarding this variable. Depression scores in both groups were significantly reduced during the study, but there was no significant difference between the groups. The correlation between increase in physical fitness and reduction in depression scores was low. The study indicates that the antidepressive effects associated with exercises are not restricted to aerobic forms of training.

The Structure of Maladaptive Schemas: A Confirmatory Factor Analysis and a Psychometric Evaluation of Factor-Derived Scales

One thousand and thirty-seven psychiatric patients and non-patients from six different sites completed the 205-item Young Schema Questionnaire or its shortended form, the 75-item Young Schema Questionnaire-S. Among 888 of the subjects, who all were patients, a confirmatory factor analysis (CFA) of the 75 items included in both forms of the questionnaire clearly yielded the 15 Early Maladaptive Schema (EMS) factors rationally developed by J. E. Young (1990). Confirmatory factor analyses, testing three models of the higher-order structure of the 15 EMSs, indicated that a four-factor model was the best alternative. The results slightly favored a correlated four second-order factor model over one also including a third-order global factor. The four factors or schema domains were Disconnection, Impaired Autonomy, Exaggerated Standards, and Impaired Limits. Scales derived from the four higher-order factors had good internal and test–retest reliabilities and were related to DSM-IV Cluster C personality traits, agoraphobic avoidance behavior, and depressive symptoms.

Physical activity and exercise dependence during inpatient treatment of longstanding eating disorders: An exploratory study of excessive and non‐excessive exercisers

OBJECTIVE To describe changes in physical activity (PA) and exercise dependence score during treatment of eating disorders (ED), and to explore correlations among changes in PA, exercise motivation, exercise dependence score and ED psychopathology in excessive and non-excessive exercisers. METHOD Thirty-eight adult females receiving inpatient treatment for anorexia nervosa, bulimia nervosa or ED not otherwise specified participated in this prospective study. Assessments included accelerometer assessed PA, Exercise Dependence Scale, Reasons for Exercise Inventory, ED Examination, and ED Inventory. RESULTS Amount of PA was significantly reduced in non-excessive exercisers during treatment, in excessive exercisers there was a trend towards reduced amount of PA from admission to discharge. In excessive exercisers, reduced ED psychopathology was correlated with reduction in exercise dependence score and perceived importance of exercise to regulate negative affects, but not with importance of exercise for weight/appearance. These associations were not found in non-excessive exercisers. DISCUSSION Excessive exercise is an important issue in longstanding ED, and the excessive exercising patients need help to develop alternative strategies to regulate negative affects.

A comparison of cognitive therapy, applied relaxation, and nitrous oxide sedation in the treatment of dental fear.

The aim of this study was to investigate the short-term efficacy of cognitive therapy and applied relaxation in dental fear treatment and to compare these methods with conventional pharmacological sedation (nitrous oxide sedation). Patients (n = 65) with severe dental fear were randomly assigned to the different treatment methods and received 10 weekly sessions of individual therapy. Dropout rates were low, and all patients who completed the therapy sessions were able to receive dental treatment. Scores on dental fear tests were significantly reduced compared with pretreatment level for all treatment groups. There were no major differences between treatment methods in this short-term perspective.

Five-year prospective study of personality disorders in adults with longstanding eating disorders.

OBJECTIVE To (1) report the occurrence of personality disorders (PDs) in adults with eating disorders (EDs) during inpatient treatment, and at 1-, 2-, and 5-year follow-up, (2) compare the changes of PDs in anorexia nervosa (AN), bulimia nervosa (BN), and eating disorder not otherwise specified (EDNOS), and (3) investigate if recovered patients had lower frequency of PDs. METHOD Seventy-four patients with EDs were assessed with Structured Clinical Interview for DSM-IV Axis II disorders during inpatient treatment, and at 1-, 2-, and 5-year follow-up. RESULTS During inpatient treatment, 58 patients (78%) had one or more PDs and this was reduced to 32 (43%) at 5-year follow-up. Dimensional PD scores changed significantly over time in both AN, BN, and EDNOS, but no significant differences emerged among the ED groups. Recovered patients had lower frequency of PDs (p < 0.01). DISCUSSION The substantial 5-year follow-up reductions in the frequency of PDs in patients with EDs present an optimistic clinical scenario for treating patients with comorbid ED and PD.

A three-year cohort study of the relationships between coping, job stress and burnout after a counselling intervention for help-seeking physicians

BackgroundKnowledge about important factors in reduction of burnout is needed, but there is a dearth of burnout intervention program studies and their effects among physicians. The present three-year follow-up study aimed to investigate the roles of coping strategies, job stress and personality traits in burnout reduction after a counselling intervention for distressed physicians.Methods227 physicians who attended a counselling intervention for burnout at the Resource Centre Villa Sana, Norway in 2003-2005, were followed with self-report assessments at baseline, one-year, and three-year follow-up. Main outcome measures were emotional exhaustion (one dimension of burnout), job stress, coping strategies and neuroticism. Changes in these measures were analyzed with repeated measures ANOVA. Temporal relationships between changes were examined using structural modelling with cross-lagged and synchronous panel models.Results184 physicians (81%, 83 men, 101 women) completed the three-year follow-up assessment. Significantly reduced levels of emotional exhaustion, job stress, and emotion-focused coping strategies from baseline to one year after the intervention, were maintained at three-year follow-up.Panel modelling indicated that changes in emotion-focused coping (z = 4.05, p < 0.001) and job stress (z = 3.16, p < 0.01) preceded changes in emotional exhaustion from baseline to three-year follow-up. A similar pattern was found from baseline to one-year follow-up.ConclusionA sequential relationship indicated that reduction in emotion-focused coping and in job stress preceded reduction in emotional exhaustion. As a consequence, coping strategies and job stress could be important foci in intervention programs that aim to reduce or prevent burnout in help-seeking physicians.

A comparison of cognitive and guided mastery therapy of agoraphobia.

The aim of this study was to compare the efficacy of cognitive and performance-based therapy of agoraphobia. Fifty-two patients suffering from panic disorder with moderate or severe agoraphobia and considering agoraphobia as their main problem were randomly assigned to receive either cognitive therapy or guided mastery therapy in a six-week inpatient group program. Significantly more of the cognitive therapy patients attained high endstate functioning, whereas the proportion of responders in the two groups did not differ. An overall test revealed no differences between the two treatment groups on the continuous outcome measures at posttreatment. As predicted from the cognitive model of panic with agoraphobia, self-efficacy scores increased with the reduction of catastrophic belief scores in the cognitive therapy group. Inconsistent with the self-efficacy model, catastrophic belief scores did not change with the increase of self-efficacy scores in the guided mastery group. Overall, the superiority of one of the treatment methods over the other was not clearly demonstrated.

Change processes in residential cognitive and interpersonal psychotherapy for social phobia: a process-outcome study.

The purpose of this study was to test cognitive and interpersonal models for improving social phobia. Eighty patients with social phobia were randomized to 10-week residential cognitive (RCT) or residential interpersonal psychotherapy (RIPT). They completed process measures every Thursday and a sub-outcome measure every Monday. The ratings were analyzed with mixed models. Weekly changes in the process variables derived from the cognitive model (self-focus, estimated probability and estimated cost of negative social events, safety behaviors) predicted subsequent weekly changes in social anxiety. Changes in the interpersonal variable perceived acceptance by others also predicted subsequent changes in social anxiety. On the other hand, changes in social anxiety predicted changes in the four cognitive variables. There were no interactive effects of process with treatment. The cognitive variables decreased during treatment to a similar degree in both treatments. The results indicate that, to reduce social anxiety, therapy should target self-focus, estimated probability and cost of feared social events, safety behaviors, and perceived acceptance by others. The process of improvement may involve positive cycles in that a reduction of social anxiety, in turn, appeared to impact self-focus, probability, cost, and safety behaviors.

Personality traits among panic disorder with agoraphobia patients before and after symptom-focused treatment

The first aim of this study was to examine the relationship between change of the agoraphobic state during treatment and personality change. The second aim was to examine the potential effect of PD traits on symptom change during and after treatment. Patients (N = 46) suffering from panic disorder with moderate or severe agoraphobia and considering agoraphobia as their main problem were randomly assigned to receive either cognitive therapy or guided mastery therapy in a 6-week inpatient group program. From before to 1 year after the end of treatment, the number of avoidant and dependent traits decreased significantly. Among changes during treatment on various symptom and cognitive variables, only change in catastrophic beliefs was significantly related to reduction in avoidant and dependent traits. Number of dependent traits at pretreatment was related to less improvement from pretreatment to 1-year follow-up on the symptom and cognitive scales.

Assessment of depression: comparison between Beck Depression Inventory and subscales of Comprehensive Psychopathological Rating Scale

The purpose of this study was to investigate the relationship between self‐rating and therapist rating in nonpsychotic patients with unipolar depressive disorders. We also wanted to find out whether the presence of personality disorders would influence the results. At admission and discharge 117 patients filled in the Beck Depression Inventory (BDI) and were rated by a therapist on the Comprehensive Psychopathological Rating Scale (CPRS). Based on the CPRS‐scores, two indices of depression were calculated: CPRS‐dep and Montgomery Åsberg Depression Rating Scale (MADRS). Sixty‐three patients had DSM‐III‐R major depression, 30 had dysthymic disorder, while 24 had no depressive disorder. Eighty suffered from one or more personality disorders, mostly within cluster C. The self rating (BDI) and therapist ratings (CPRS‐dep and MADRS) were strongly intercorrelated, with a nonsignificant tendency for weaker correlations in patients with personality disorders. All scales were useful to separate depressed from non‐depressed, and to discriminate between major depression and dysthymic disorder, with a tendency in favour of BDI. As cut‐off scores for major depression we recommend the sum score of 23 on the BDI, and mean scores of 1 on CPRS‐dep and 1.1 on MADRS on a 0–3 scale. When these values are used, 70–79% of patients are correctly classified.
