Prevalence and patterns of anxiety and depression in patients undergoing elective percutaneous transluminal coronary angioplasty.

BACKGROUND: The use of elective percutaneous transluminal coronary angioplasty (PTCA) as a treatment for coronary heart disease is increasing. Despite this, little is known about the prevalence and patterns of anxiety and depression experienced by patients undergoing and recovering from this procedure. Anxiety and depression are factors known to negatively influence recovery after a cardiac event. OBJECTIVE: The purpose of this study was to (1) describe the levels of anxiety and depression reported by patients pre- and postelective PTCA, and (2) determine associations evident between anxiety and depression and the sociodemographic and clinical variables of gender, marital status, history of acute myocardial infarction, and attendance at cardiac rehabilitation. METHODS: In this descriptive, repeated-measures investigation, patients (n = 140) were requested to complete the Spielberger State Trait Anxiety Inventory and Cardiac Depression Scale (CDS) at three time points: 0(1) before admission for elective PTCA (T(1)); (2) 6 to 8 weeks (T(2)) after PTCA; and (3) 6 to 8 months (T(3)) after PTCA. RESULTS: A typical participant was male (75%), of European ethnicity (90%), aged 62 years (standard deviation = 10.7) with single or double vessel disease, and had attended cardiac rehabilitation in the past. At T(1), 16% of men and 24% of women had state anxiety scores comparable to those experienced by neuropsychiatric patients. Trait anxiety scores remained relatively constant over time; higher scores at T(1) were associated with past acute myocardial infarction. CDS scores at T(2) and T(3) were significantly lower than those at T(1). However, an unexpected increase in CDS scores occurred at T(3), compared with T(2). At T(3), 14% of men and 10% of women were depressed, relative to T(1). CONCLUSION: The findings lend support for the closer surveillance of emotional status in this population. Specialist nurses have the potential to play a greater role in identifying those at risk of developing anxiety and depression. However, this unmet need will remain unmet until specialist nurses who spend the most face-to-face time with patients are equipped with the skills and resources to systematically identify those "at risk."

The Chinese version of the PSS:PICU.

BACKGROUND: Before an established research instrument is adopted for use in a cultural context different from that where it was developed, its validity and reliability must be reassessed so that it is applicable to and congruent with the culture of the population under study. OBJECTIVES: To translate the Parental Stressor Scale: Pediatric Intensive Care Unit (PSS:PICU) into Chinese, and to evaluate the psychometric properties of the Chinese version. METHODS: A prospective study investigated 81 parents of 75 children admitted to a PICU in two hospitals. Parents completed the Chinese versions of the PSS:PICU and the state anxiety scale of the Spielberger State-Trait Anxiety Inventory. RESULTS: Factor analysis and item-subscale correlations supported the conceptual dimensions of the original instrument. The internal consistency of the Chinese version was high. Most of the subscales were moderately correlated with each other and strongly correlated with the total score. The convergent validity with the state anxiety scale in the Chinese version of the Spielberger State-Trait Anxiety Inventory was reflected by a weak correlation for the overall scale and for the subscales. CONCLUSIONS: Although some satisfactory psychometric properties of the translated instrument were found in this study, they should be used as a reference for studies with larger samples. The current form is not ready for wide dissemination until more concrete research evidence is available.

Validation of the Cardiovascular Limitations and Symptoms Profile (CLASP) in chronic stable angina.

PURPOSE: This study aimed to establish the reliability, validity, and sensitivity of the Cardiovascular Limitations and Symptoms Profile (CLASP) in a group of patients with chronic stable angina. METHODS: After 226 patients with angina had been recruited, they were randomly allocated to one of three groups: a 10-week hospital-based angina management program (n = 75; men = 56; age = 60 +/- 8 years), routine care (n = 74; men = 52; age = 61 +/- 7 years), and exercise therapy (n = 77; men = 60; age = 60 +/- 7 years). All the patients were assessed with CLASP on two occasions: at baseline and at 10 weeks. The Sickness Impact Profile (SIP), the Hospital Anxiety and Depression Scale (HADS), and the Sleep Problems Questionnaire (SPQ) also were administered at the same time. RESULTS: Significant positive correlations between the actual number of angina episodes and the CLASP angina subscale scores (r =.60, P <.001) were observed. The CLASP subscale scores for shortness of breath (r = -.36; P <.001) and ankle swelling (r = -.24; P <.001) were significantly correlated with the total treadmill time. The CLASP tiredness subscale score showed a significant positive correlation with the SPQ score (r =.48; P <.001). The CLASP subscale scores were significantly correlated with their corresponding SIP subscale scores: the tiredness score with the sleep and rest score (r =.49; P <.001), the social and leisure score with the recreation and pastimes score (r =.41; P <.001), the home score with the home management score (r =.45; P <.001), and the mobility score with the mobility (r =.37; P <.001) and total treadmill time scores (r = -.49; P <.001). CONCLUSIONS: The findings show CLASP to be a reliable, valid, sensitive measure of health-related quality of life in patients with chronic stable angina. Before it can be recommended for all patients with heart disorders, similar data will be required from other diagnostic groups such as patients with heart failure or those who have sustained an acute myocardial infarction.
