Study Notes

Importance of Evidence in Allied Health

Research informs clinical decision making and supports high-quality, ethical care.
Evidence-based practice (EBP) is a dynamic process incorporating research, patient needs, clinical expertise, and service context.

EBP Frameworks and Processes

EBP/E^4^BP Framework: emphasizes key components like patient values and needs, service context, clinical expertise, and research findings.
5 Steps of the EBP Process: P (Problem/Patient), I (Intervention/interest), C (Comparison), O (Outcome) framework helps structure clinical questions for effective research.

Understanding Research

Quantitative research: focuses on numerical data, investigating relationships, cause-and-effect, frequency, course/prognosis, and population/sample characteristics.
Qualitative research: explores quality, themes, and experiences, providing deeper insights into phenomena.

Critical Appraisal

CASP Critical Appraisal Checklist: helps systematically evaluate research by ensuring important factors and considerations are taken into account.
Consistency in decision-making is promoted by using a structured appraisal framework.

Knowledge Translation

Knowledge translation (KT): bridges the gap between research evidence and clinical practice through strategies that enhance awareness and encourage behavior change aligned with research findings.
KT phases: Knowledge creation, integration, implementation, and dissemination to promote effective knowledge use and improve services by engaging clinicians, the public, and consumers.

Week 1 Assignment

Article: "Sharing and valuing older Aboriginal people's voices about social and emotional wellbeing services: a strength-based approach for service providers" by Gibson et al. (2020)
Focus: Analyze Methods and Results sections (pp. 482-485) to address the following:
- How do the methods reflect the AH&MRC principles?
- Discuss the research approval process and its importance.
- Identify the three themes and how subthemes relate to the main themes.

Information Retrieval and Sources

Bibliographic databases: CINAHL and PubMed offer access to peer-reviewed literature.
Grey literature: Includes government reports, statistics, and non-peer-reviewed research that informs practice and guides additional research needs.
Unpublished research: May not be peer-reviewed or rigorously evaluated.

Measurement

Measurement in allied health: involves assigning numerals to variables influencing people's characteristics and behavior.
Constructs: Represent underlying concepts and traits influencing behavior.

Assessment

Different Assessment Types:
- Discriminative: Differentiates between individuals with and without a condition (e.g., diagnostic or screening tools).
- Evaluation: Measures changes over time (e.g., outcome assessment).
- Predictive: Forecasts future ability.

Validity and Reliability

Validity: Determines if an assessment measures what it intends to, allowing for meaningful interpretation.
Reliability: Focuses on the consistency of scores and minimization of errors, ensuring confidence in data collection and analysis.
- Systematic error: Predictable, consistent, and modifiable error.
- Random error: Occurs due to chance, influencing accuracy.

Types of Reliability

Test-Retest Reliability: Measures the consistency of results across repeated administrations of the same test.
- Considerations: time between administrations, test environment consistency, carryover effects.
- Statistics used: Intraclass Correlation Coefficient (ICC), Kappa Statistic, % Agreement, Standard Error of Measurement, Pearson or Spearman Correlation (ICC preferred).
Rater Reliability: Evaluates the consistency of ratings among different raters.
- Intrarater Reliability: Stability of results by one rater across multiple trials.
- Interrater Reliability: Agreement between two or more raters assessing the same subject.
- Statistics used: Intraclass Correlation Coefficient (ICC), Kappa Statistic, % Agreement, Standard Error of Measurement, Pearson or Spearman Correlation (ICC preferred).
Internal Consistency: Examines the extent to which items on an assessment measure various aspects of the same characteristic.
- Statistics: Cronbach’s Alpha (α), item-to-total correlations (Pearson product-moment), Spearman-Brown prophecy statistic (for split-half reliability).

Content Validity

Content validity: Ensures that the assessment items reflect the intended domain of measurement.

Rules of Measurement

Measurement requires established criteria for assigning values and clear definitions of attributes.

Descriptive Statistics

Population and Samples:
- Population: Entire group of interest.
- Sample: Subset of the population, used to draw conclusions about the population.
- Sampling error: Occurs because a sample may not perfectly reflect the entire population.
Descriptive statistics: Summarize and describe data characteristics.
- Central tendency: Measures the typical or average value (mean, median, mode).
- Spread and variance: Show the variability of data (range, minimum/maximum values, quartiles/interquartile range, standard deviations).
