Summary
The Effective Consumer Scale (EC-17) measures essential healthcare management skills. This study found the EC-17 captures unique patient attributes not covered by other scales, supporting its use in developing new interventions.
Area of Science:
- Health outcomes research
- Patient self-management
- Psychometrics
Background:
- The Effective Consumer Scale (EC-17) assesses key skills for healthcare management.
- Responsiveness of the EC-17 to interventions needed evaluation.
- Existing scales like ASE and PAM may not fully capture consumer effectiveness.
Purpose of the Study:
- To test the responsiveness of the EC-17.
- To compare the EC-17 with the Arthritis Self-Efficacy (ASE) and Patient Activation Measure (PAM) scales.
- To determine if the EC-17 measures unique aspects of patient self-management.
Main Methods:
- Participants in an Arthritis Self-Management Program (ASMP) completed the EC-17 at baseline and week 6.
- Responsiveness was assessed by calculating mean change and standard deviations.
- EC-17 scores were compared to ASE and PAM scales.
Main Results:
- The EC-17 showed moderate correlation with the PAM and was more efficient than ASE in detecting improvements post-ASMP.
- Most EC-17 items with significant deficits were not covered by ASE or PAM.
- 327 participants from two intervention waves (2006, 2007) were included.
Conclusions:
- The EC-17 measures distinct skills and attributes compared to ASE and PAM.
- Measuring effective consumer skills is valuable.
- Interventions, including online decision aids, should incorporate EC-17 categories.

01:16Response Surface Methodology
Response Surface Methodology (RSM) is a collection of statistical and mathematical techniques used to develop, improve, and optimize processes. It is particularly valuable when many input variables or factors potentially influence a response variable.
The process of RSM involves several key steps:

01:29Self-Evaluation Maintenance Model
The Self-Evaluation Maintenance (SEM) model offers a psychological framework to understand how individuals’ self-esteem is influenced by the achievements of others, particularly those with whom they share close personal bonds. The SEM model operates when personal rather than social identity guides individuals. Central to this model is the notion that individuals have an inherent desire to preserve a favorable self-image, which is continuously shaped by interpersonal comparisons and...
01:22Dose-Response Relationship: Potency and Efficacy
The potency of a drug is the measure of its ability to produce a biological response and can be compared by looking at the half-maximum effective concentration or EC50 values of different drugs. A lower EC50 value indicates higher potency of the drug. In the dose–response curve of two antihypertensive drugs, candesartan and irbesartan, a significant difference is observed in their EC50 values. A lower EC50 value for candesartan indicates that it is more potent than irbesartan, as it produces...
01:22Self-Report Tests of Personality
Self-report inventories are objective personality assessments that use multiple-choice items or numbered scales, typically ranging from 1 (strongly disagree) to 5 (strongly agree). They are often called Likert scales after Rensis Likert. These inventories are widely used due to their ease of administration and cost-effectiveness. One of the most prominent examples is the Minnesota Multiphasic Personality Inventory (MMPI), initially developed in the 1940s to assess abnormal personality traits.
01:25Factors Affecting Perception
Perception is influenced by perceptual set, context, motivation, and emotion. Perceptual set, or perceptual expectancy, refers to the tendency to perceive things in a particular way, influenced by previous experiences and expectations. This phenomenon affects the interpretation of stimuli, creating a set of mental tendencies and assumptions that impact sensory perceptions of sound, taste, touch, and sight.

02:16Stereotype Content Model
The Stereotype Content Model (SCM) was first proposed by Susan Fiske and her colleagues (Fiske, Cuddy, Glick & Xu, 2002; see also Fiske, 2012 and Fiske, 2017). The SCM specifies that when someone encounters a new group, they will stereotype them based on two metrics: warmth—or that group’s perceived intent, and how likely they are to provide help or inflict harm—and competence—or their ability to carry out that objective. Depending on the warmth-competence categorization, a person will feel...
