A researcher is exploring the impact of a mindfulness app on reducing anxiety levels among university students before exams. Participants use the app for two weeks, and their anxiety levels are measured before and after the intervention. What potential carryover effect should the researchers be most concerned about?
- Fatigue effects, due to the repetitive nature of mindfulness exercises leading to decreased engagement and effectiveness over time.
- Placebo effects, due to some students increasing their performance because they may expect that the app will have a positive effect.
- Experimenter-expectancy effects, where the researchers communicate (intentionally or unintentionally) their hypotheses.
- Practice effects, where students inadvertently improve anxiety-coping skills simply by repeatedly measuring their anxiety. (correct)

Study Notes
- Scientific research aims to broaden knowledge through the systematic study of phenomena.
- This begins with formulating a research question to guide the investigation
Ethical Considerations in Research
- Research ethics should inform all aspects of the study, from its inception to data storage and reporting
- Institutional ethics review is required for research involving living organisms, tissue, or personal data in Australia
- Institutional ethics review ensures adherence to ethical standards, participant well-being, and scientific integrity
Key Ethical Values and Principles
- Include respect, beneficence, merit and integrity, and justice
- Merit and integrity relates to the quality of the study
- Integrity relates to the intentions and conduct of the researchers
- Justice refers to fair treatment and includes distributive and procedural justice
Beneficence
- Involves minimizing harm and balancing risks against potential benefits.
- It involves transparency about the level of harm
- Respect involves recognizing the intrinsic value of human beings and protecting autonomy, privacy, and confidentiality
Additional Ethical Considerations for Vulnerable Populations
- Vulnerable populations have diminished ability to safeguard their own interests or experience disadvantage
- Researchers working with vulnerable populations need to have an understanding of the sociocultural contexts and be aware of their own assumptions
- Research should directly benefit the studied group, and the group should define risks and benefits
Guidelines for Aboriginal and Torres Strait Islander Communities
- Guidelines recognize historical exploitation and mistrust
- The need to improve researcher practices, strengthen research capabilities, and enhance the rights of Indigenous people
- Six core values: spirit and integrity, cultural continuity, equity, respect, reciprocity, and responsibility
Ethical Research with CALD Populations
- It should be culturally informed, high quality, safe, and actionable
- Assemble a culturally competent team.
- Address community needs and inequities.
Ethical Research with LGBTQIA+ Populations
- Respect the dignity of all research participants
- Engage with the taxonomy and language of participants
- Examine assumptions about who is and isn't in the sample population
- Recognize intersectionality and its impact
Selecting a Research Design
- The nature of the research dictates the design type
- Exploratory questions suit qualitative research
- Questions about cause and effect require experimental designs
Quantitative Research: Experimental Designs
- It involves data represented numerically and analyzed statistically
- It tests cause-effect relationships by manipulating variables
- Experimental manipulation involves varying conditions
- Experimental control minimizes extraneous variables
Between-Groups Experimental Designs
- It divides participants into separate groups with different conditions
Simple Two-Group Experiments
- One experimental group and one control group
Experiments with three of more groups
- Done to help rule out alternative explanations for an effect.
Factorial Experiments
- Tests the effect of more than one independent variable at a time.
Repeated Measures (Pre-Post) Experimental Designs
- Measure a single group of participants at multiple time points.
- An example design variation: Simple two condition design
A-B-A Designs
- The sequence is baseline (A), manipulation (B), and return to baseline (A)
Mixed Experimental Designs
- Elements from both between-groups and repeated measures experimental designs
- Combines multiple groups with multiple measurements to reduce confounding effects
Strategies for Controlling Extraneous Variables
- Random assignment to groups, inclusion criteria, and repeated measures designs
Expectancy Effects
- Placebo effects involve behavior changes due to expectations
- Experimenter-expectancy effects involve unintentional influence by the researcher
Strategies for controlling expectancy effects
- Single-blind or double-blind procedures, and no-treatment control conditions help
Carryover Effects
- Practice, fatigue, and context/priming effects can occur in repeated measures designs
- Counterbalancing is used to address carryover effects for more accurate results
When to Use an Experimental Design
- Use when focused on a cause-effect relationship
- When the independent variables can be controlled
- Random assignment of participants possible
Non-Experimental Quantitative Research
- It does not involve manipulation of variables
- Used to measure the extent of a phenomenon or relationships between variables
Defining characteristics of non-experimental research
- No active manipulation by the researcher
Types of Non-Experimental Research
- Include single variable research and cross-sectional correlational research
Longitudinal Cohort Research
- Repeated measurements from participants without manipulation
Quasi-Experimental Research
- Compares non-randomly allocated groups
- Case-control studies are common
Issues That Prevent Claims of Causality
- Lack of experimental manipulation and inability to establish time-based precedence
When to Use Non-Experimental Research
- When you’re measuring a single variable or non-causal relationships
- When a cause-effect relationship exists, but variable manipulation isn’t possible
- When the study is exploratory
Qualitative and Mixed Methods Research
- Qualitative: Data is not easily reduced to numbers
Purpose of Qualitative Research
- To deeply understand human experiences and behaviors
Key Characteristics of Qualitative Research
- Data can include quotes, diary submissions, digital data, or objects/artifacts
- Common data collection methods include: interviews and focus groups
Analyzing Data using Qualitative Research
- The type of data collected includes quotes from participants, field notes, digital data such as social media comments and email communications or artifacts
- A common component: reflexivity
Common Approaches to Qualitative Research
- Designs are narrative inquiry, phenomenology, grounded theory, and case study
Mixed-Methods Research
- Combines elements of both quantitative and qualitative research
- Benefits include: enriching study results and triangulation
Systematic Approaches to Summarizing Past Research
- It is a critical analysis and synthesis of past research
Systematic Literature Reviews (SLRs)
- Identify what is currently known related to to the area of study
- They use rigorous, systematic approaches to planning, searching, evaluation, and finding sources.
Key Characteristics of an SLR
- All procedures are systematic, planned beforehand, and fully reported
Systematic Search Procedures for SLR
- Develop clearly defined search strategies and use different databases
- Researchers report the results of their search, including how many articles were initially identified
Screening Studies Against Eligibility Criteria in SLR
- Researchers systematically review results against eligibility criteria
- Use pre-defined inclusion/exclusion criteria to specify the population of interest
Evaluation of Study Quality for SLR
- Access whether the design was appropriate
Reporting Procedures for SLR
- Reported following precise guidelines
Meta-Analyses
- Extend SLRs through quantitative synthesis of past research
When to Use An SLR
- Assess what is known or unknown about a phenomenon
When to Use a Meta-Analysis
- Calculate the average magnitude of an effect
