Effects of Cognitive Behavior Therapy on Quality of Life in Paroxysmal Atrial Fibrillation Patients

Peking University People's Hospital102 enrolled

Overview

Health-Related Quality of Life (HRQoL) was commonly impaired in atrial fibrillation patients. Depression, anxiety, and illness perception are psychological correlates of HRQoL. Our previous study had shown good effects of CBT on the quality of life in AF patients. This study aimed to establish the long-term efficacy of CBT on both psychological distress and HRQoL. Method: The study was a prospective, open study, pseudo-randomization with a pretest-posttest design and a 6-month follow-up. A total of 102 patients with paroxysmal AF were enrolled, and 90 patients were assigned (1:1) to 10 weeks of CBT focused on anxiety symptoms or to treat as usual in the end. Item Short Form Health Survey (SF-12), GAD-7, PHQ-9, University of Toronto Atrial Fibrillation (AFSS), and Brief Illness Perception Questionnaire (BIPQ) were measured as outcomes.

Outcomes

Primary Outcomes

Change from baseline score of The 12-item Health Survey Short Form (SF-12) at 10 weeks and 6 months

SF-12 is a 12-item, multipurpose short-form survey that is used to measure generic HRQoL (derived from the SF-36). The findings are weighted and summed to produce interpretable scales for a participant's physical and mental well-being. SF-12 is divided into two domains: the physical component summary (PCS) and the mental component summary (MCS). Each domain scores from 0 to 100, with higher scores indicating a better health status

Time frame: Both groups were assessed the SF-12 three times, respectively at baseline, 10 weeks later and 6 month later

Secondary Outcomes

Brief Illness Perception Questionnaire (BIPQ)

The Brief Illness Perception Questionnaire (BIPQ) is a nine-item questionnaire that assesses how people feel about illnesses across nine categories. The individual nine domain scores were added together to create a composite BIPQ score. A higher BIPQ score suggests that the psychological burden of illness is greater (range: 0-80). The BIPQ assesses the following illness perception domains: identity (symptoms experienced); timeline-acute/chronic (perception of the length of disease); consequences (effect of disease on one's life); personal control (control over disease); treatment control (perception of treatment impact); emotional representations (emotional effect of the disease); illness coherence (understanding of disease); illness concern (concern about the disease); and cause (perceived cause of disease). The cause item is an open-ended question that asks patients to rank the top three factors they believe caused their disease

Time frame: Both groups were assessed the BIPQ three times, respectively at baseline, 10 weeks later and 6 month later

University of Toronto Atrial Fibrillation Severity Scale (AFSS)

University of Toronto Atrial Fibrillation Severity Scale (AFSS)-a 14-item disease-specific scale consisting of three parts. Part 1 measures patients with atrial fibrillation overall life satisfaction and frequency, duration of atrial fibrillation attacks, and severity; Part 2 measures patient utilization rates; Part 3 is divided into symptom subscales, including 7 common symptoms of atrial fibrillation (heart palpitations, dyspnea at rest, dyspnea with activity, exercise intolerance, vertigo, fatigue at rest, and chest pain) and the corresponding frequency of attacks. In this study, the symptom part was selected as the AF symptoms measurement.

Time frame: Both groups were assessed the AFSS symptoms subscale three times, respectively at baseline, 10 weeks later and 6 month later

The Generalized Anxiety Disorder Questionnaire (GAD-7)

The Generalized Anxiety Disorder Questionnaire (GAD- 7) is a 7-item measure of anxiety symptoms, using a four-point Likert-type scale. The GAD-7 asks how often people have suffered from the seven core symptoms of GAD within the last two weeks with the response options being 'not at all', 'on some days', 'on more than half of the days', and 'almost every day' (scored 0-3, with a total score ranging from 0 to 21). A sum score of≥10 indicates clinically relevant anxiety.

Time frame: Both groups were assessed the GAD-7 three times, respectively at baseline, 10 weeks later and 6 month later

The Patient Health Questionnaire-9 (PHQ-9)

The Patient Health Questionnaire-9 (PHQ-9) is a nine-item tool used to measure the severity of depression over the previous 2 weeks (range 0-27). he PHQ-9 was chosen above other depression screening measures because it is easy to administer and outperforms the structured clinical interview for the Diagnostic and Statistical Manual of Mental Disorders-IV as the standard criterion.

Time frame: Both groups were assessed the PHQ-9 three times, respectively at baseline, 10 weeks later and 6 month later
