Exploring mechanisms of change: the relationships between cognitions, symptoms, and quality of life over the course of group cognitive-behaviour therapy

Determinants of quality of life improvements in anxiety and depressive disorders-A longitudinal study of inpatient psychotherapy

Background

Quality of life (QoL) is substantially impaired in patients with anxiety disorders (AD) and depressive disorders (DD) and improvements in symptom burden after psychotherapy are not always paralleled by similar improvements in QoL. So far, little is known about treatment outcome in terms of QoL and predictors of QoL improvements following inpatient psychotherapy with a focus on cognitive behavior therapy (CBT). The current study aimed at investigating the relationship between changes in symptoms and QoL across different life domains. Additionally, predictors of a positive treatment outcome were evaluated.

Methods

122 patients with AD and/or DD undergoing an 8-weeks inpatient CBT program completed self-report measures of psychopathological symptoms and QoL at pre- and post-treatment. Mixed effects models were used to investigate changes, a confirmatory factor analysis was applied to analyze the latent factor structure of the anxiety sensitivity index and binary logistic regression analyses were performed for predictors of QoL improvements.

Results

Patients showed moderate to strong decreases in anxious and depressive symptoms and moderate to strong improvements in general QoL, particularly in the psychological and physical QoL subdomains. Changes in symptom burden correlated most strongly with psychological and physical QoL. In addition, poor QoL before treatment and low levels of specific anxiety sensitivity symptoms (items 1 and 5) significantly predicted improvement in QoL.

Conclusion

Patients with poor QoL who are not as inhibited to openly express their anxious feelings particularly benefit from inpatient psychotherapy (individual and group) to improve their QoL. In contrast, our research suggests that patients who are too anxious to openly express their nervousness should receive additional social skills training, more focused treatment to build sufficient self-confidence to better engage in the treatment program.

An exploration of the relationships between patient application of CBT skills and therapeutic outcomes during a two-week CBT treatment

The application of Cognitive Behavioural Therapy (CBT) skills are believed to be a mechanism of therapeutic change in treatment. Research has shown that the application of CBT skills affects outcomes, however, the way these relationships may change during treatment has not been explored. In this study, a naturalistic observational approach is used to examine the relationships between patients' wellbeing, symptoms, and the application of CBT skills throughout treatment. It is hypothesized that the application of CBT skills would lead to an increase in patients reported wellbeing, and a decrease in symptoms. Additionally, it was hypothesized that the application of CBT skills affects wellbeing and symptoms at different points in therapy. A sample of 584 patients in a two-week CBT treatment completed session-to-session measures of wellbeing, symptoms, and their application of CBT skills. Results of an autoregressive cross-lagged path analysis indicated that in the early stages of treatment the application of CBT skills predicted patient wellbeing but not symptoms. At the later stages of therapy, the application of CBT skills predicted both patient wellbeing and symptoms. At no point in treatment did patient wellbeing or symptoms predict the later application of CBT skills. Implications and future directions for research are discussed.

The Relationship between Symptoms and Social Functioning over the Course of Cognitive Behavioral Therapy for Social Anxiety Disorder

Background

The present study is aimed at investigating the relationship between changes in symptoms and changes in social functioning during cognitive behavioral therapy (CBT) for social anxiety disorder (SAD).

Methods

Ninety-six patients with SAD were treated with manualized group CBT. Measures of social anxiety symptoms, depression symptoms, cognition, and social functioning were administered at baseline and endpoint. Using multiple regression analysis, we examined the associations between the changes in four aspects (work, home management, social leisure activities, and private leisure activities) of social functioning as dependent variables and the changes in four factors (social interaction, public speaking, observation by others, and eating and drinking in public) in social anxiety symptoms, depression symptoms, and cognition as independent variables.

Results

The changes in work functioning were predicted by the changes in the public speaking factor in social anxiety symptoms. The changes in depression symptoms predicted the changes in home management. The significant predictors of changes in social leisure activities were the changes in the social interaction factor and depression symptoms. The changes in private leisure activities were predicted by the changes in the observation by others factor. The changes in cognition predicted nothing.

Conclusion

The present study suggested that the changes in social anxiety or depression symptoms may predict several aspects of social functioning changes in patients with SAD over the course of CBT. In order to improve social functioning, our results may be useful for selecting the fear or feared situation in CBT for SAD. Trial Registration.

The relationships between symptoms and quality of life over the course of cognitive-behavioral therapy for panic disorder in Japan

INTRODUCTION

This study examined the relationships between changes in symptoms and changes in quality of life (QOL) during cognitive-behavioral therapy (CBT) for panic disorder (PD).

METHODS

We treated 198 PD patients with group CBT in Japan. Using multiple regression analysis, we examined the associations between changes in QOL and changes in PD symptoms or comorbid psychological symptoms during CBT.

RESULTS

Changes in anticipatory anxiety, agoraphobic fear/avoidance, and somatization were significant predictors of changes in some aspects of QOL.

DISCUSSION

It might be useful to decrease somatization, anticipatory anxiety, and agoraphobic fear to improve QOL in CBT for PD.

Global Quality of Life Among WHI Women Aged 80 Years and Older

BACKGROUND

The number of older adults living to age 80 and older is increasing rapidly, particularly among women. Correlates of quality of life (QOL) in very advanced ages are not known. We examined the association of demographic, social-psychological, lifestyle, and physical health variables with global QOL in a Women's Health Initiative (WHI) cohort of women aged 80 and older.

METHODS

26,299 WHI participants, who had completed a recent psychosocial and medical update, were included in these analyses. Global QOL was assessed by a single item, asking the women to rate their overall QOL on a scale from 0 to 10. Characteristics of the women were examined by the level of their transformed global QOL scores (≤50, 50-70, ≥70), and multiple regression was used to examine which demographic, social-psychological, lifestyle and health variables were independently associated with higher global QOL.

RESULTS

Social-psychological and current health variables were more strongly associated with global QOL than a history of selected comorbid conditions. In particular, higher self-rated health and fewer depressive symptoms were the most strongly associated with better global QOL in WHI women ≥80 years.

CONCLUSIONS

Interventions to reduce depressive symptoms and improve health may lead to better self-reported health and global QOL among older women. Physical and mental health screenings followed by evidence-based interventions are imperative in geriatric care.
