The Sense of Self: Reflected Self-Appraisal and Social Comparison02:57

The Sense of Self: Reflected Self-Appraisal and Social Comparison

56.1K
According to Charles Cooley, we base our image on what we think other people see (Cooley 1902). We imagine how we must appear to others, then react to this speculation. We don certain clothes, prepare our hair in a particular manner, wear makeup, use cologne, and the like—all with the notion that our presentation of ourselves is going to affect how others perceive us. We expect a certain reaction, and, if lucky, we get the one we desire and feel good about it. But more than that, Cooley...

COPD: Pathogenesis and Clinical Features

1.9K
Chronic obstructive pulmonary disease (COPD) is a group of lung conditions that progressively worsen over time, including chronic bronchitis and emphysema. This cluster of diseases collectively leads to a gradual and irreversible decline in lung function over time.
The primary cause for the onset of COPD is cigarette smoking and exposure to air pollution. These hazardous factors initiate a chain reaction within the lungs, resulting in chronic inflammation, damage to the airways, and a...

COPD: Management Using Bronchodilators and Corticosteroids

Chronic obstructive pulmonary isease (COPD) involves a group of progressive lung disorders characterized by persistent airflow limitation and chronic respiratory symptoms. Asthma-COPD Overlap Syndrome (ACOS), encompassing features of both asthma and Chronic obstructive pulmonary disease (COPD), is a group of progressive lung disorders that includes chronic bronchitis, emphysema, and refractory (non-reversible) asthma. ACOS leads to complex clinical presentations that combine the inflammatory...

Rate-Determining Steps

Relating Reaction Mechanisms
In a multistep reaction mechanism, one of the elementary steps progresses significantly slower than the others. This slowest step is called the rate-limiting step (or rate-determining step). A reaction cannot proceed faster than its slowest step, and hence, the rate-determining step limits the overall reaction rate.
The concept of rate-determining step can be understood from the analogy of a 4-lane freeway with a short-stretch of traffic-bottleneck caused due to...

Data Reporting and Recording

5.5K
Reporting and recording are crucial in data documentation. The timely, thorough, and accurate documentation of facts is essential when recording patient data. Failure to record findings during an assessment or interpretation of a problem will result in loss of information and make the patient document unreliable. The reader is left with general impressions if the information is not specific. A recording is documenting data of the individual's health information in a traceable, secure, and...

Classical Conditioning in Daily Life

2.3K
Classical conditioning, a fundamental principle of associative learning, explains various phenomena observed in daily life, such as fear development, the placebo effect, taste aversion, and drug habituation. These applications demonstrate the profound impact of associative learning on human behavior and physiological responses.
John B. Watson and Rosalie Rayner famously demonstrated the development of fear through classical conditioning in their experiment with Little Albert. They paired the...

Summary
This summary is machine-generated.

A new task-oriented checklist effectively measures physical activity (PA) in COPD patients, correlating with daily step counts. This tool can aid clinicians in exercise counseling to boost PA in individuals with chronic obstructive pulmonary disease.

Area of Science:

  • Pulmonary Medicine
  • Rehabilitation Science
  • Health Behavior

Background:

  • Low physical activity (PA) is linked to adverse health outcomes in COPD, irrespective of airflow limitation.
  • Traditional self-reported PA assessments offer limited insights into patient-specific goals and motivations.
  • A novel task-oriented PA checklist was developed to address these limitations in COPD cohorts.

Purpose of the Study:

  • To develop and validate a task-oriented physical activity (PA) checklist for COPD patients.
  • To assess the performance of this checklist against pedometer-measured daily step counts.
  • To explore the clinical utility of task-oriented PA assessments in COPD management.

Main Methods:

  • Two COPD cohorts (n=109 and n=175) participated.
  • Task-oriented daily physical activity (DPA) was assessed via interviewer-administered recall (DPA-R) or self-administered checklist (DPA-C).
  • Daily step count was measured using pedometers; associations with DPA items and composite scores were analyzed using correlation and regression models.

Main Results:

  • Specific tasks like donning shoes, showering, and walking on inclines correlated with daily step counts (Pearson's rho range: 0.14-0.43).
  • A composite DPA score derived from 6 key tasks showed significant associations with baseline step counts in both cohorts (ρ=0.50 and 0.47).
  • The composite DPA score also correlated with longitudinal changes in daily step count in Cohort 1 (ρ=0.46).

Conclusions:

  • Task-oriented self-reported PA assessments provide valuable data complementing direct monitoring methods.
  • These assessments show potential for clinical application in guiding exercise counseling to enhance PA in COPD patients.
  • The developed checklist offers a practical tool for evaluating and promoting physical activity in this population.
