Summary
The Theory of Planned Behaviour (TPB) can explain evidence utilisation in health policymaking. A new TPB-based tool (EUPMT) demonstrates good reliability and validity for assessing this behaviour.
Area of Science:
- Health Policy Research
- Behavioural Science
- Measurement Tool Validation
Background:
- Theory of Planned Behaviour (TPB) is commonly used for health behaviours but rarely for health policymakers.
- Understanding factors influencing evidence utilisation in health policymaking is crucial.
Purpose of the Study:
- To design and validate a measurement tool based on the Theory of Planned Behaviour (TPB) for evidence utilisation in health policymaking (EUPMT).
Main Methods:
- A mixed-methods approach using confirmatory factor analysis.
- Study population: 373 employees from Iran's Ministry of Health and Medical Education.
- Reliability assessed via test-retest and internal consistency; validity by face, content, convergent, discriminant, and construct.
Main Results:
- Content validity: 83%; Face validity: 67%.
- Cronbach's alpha: 0.7–0.9; Test-retest reliability (intra-class correlation): 0.75–0.87.
- Confirmatory factor analysis indicated acceptable model fit (GFI=0.86, NFI=0.94, RMSEA=0.075).
Conclusions:
- The TPB effectively explains evidence utilisation behaviour in health policymaking.
- The EUPMT is a reliable and valid tool for assessing evidence utilisation in this context.
- The EUPMT can inform interventions and evaluate outcomes for improving evidence use in health policy.

01:29Reliability and Validity
14.2K
Reliability and validity are two important considerations that must be made with any type of data collection. Reliability refers to the ability to consistently produce a given result. In the context of psychological research, this would mean that any instruments or tools used to collect data do so in consistent, reproducible ways.

01:29Econometric Views (EViews)
631
Econometric Views, often stylized as EViews, is a package that merges statistical analysis with econometric studies. It is designed to provide tools for time series analysis, forecasting, and econometric model simulation. The software originated from MicroTSP software and has evolved significantly since its inception in 1981. The history of EViews is marked by a continuous effort to enhance its computational speed and user interface. It was initially developed for large computing systems but...

01:20Measurement of Bioavailability: Pharmacodynamic Methods
919
Pharmacodynamic methods provide insights into a drug's effects on physiological processes over time and play a crucial role in understanding bioavailability and therapeutic efficacy. These methods can be broadly classified into acute pharmacological and therapeutic response approaches, each with distinct mechanisms and applications.The acute pharmacological response method directly correlates a drug's physiological effects, such as ECG or pupil diameter changes, to its time course in the body.

572
Electronic Distance Measuring Instruments (EDMs) are essential tools in modern surveying, offering precise distance measurements by emitting electromagnetic signals and calculating the time required for these signals to travel to a target and return. Two primary types of signals are used in EDMs — light waves and microwaves — each suited to specific environmental and distance requirements. Light-wave-based EDMs utilize either infrared or laser light, providing high accuracy over...

01:29Measures of Intelligence
8.7K
Psychologists measure intelligence by using standardized tests that produce a score known as the intelligence quotient or IQ. To understand IQ tests, it's important to recognize the key principles behind their construction: validity, reliability, and standardization.
Validity refers to how well a test measures what it claims to measure. An intelligence test should accurately assess intelligence rather than another characteristic, like anxiety. Criterion validity is one way to evaluate this;...

01:29Self-Evaluation Maintenance Model
347
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...
