    Study Notes

    Week 2 - PSYCH 2990: Designing, Intervening, and Nudging (Jan 14, 2025)

    • Psychology study findings are not as strong as claimed.
    • Scientists replicated 100 recent psychology experiments, and more than half failed the reproducibility test.
    • Key themes covered in lecture 2 include measurement and design, internal vs. external/ecological validity, studying daily lives, brief measures, intervention and evaluation, and nudging (and intervention failure).
    • Measurement and design in applied psychology discuss methods to enhance external validity in research.
    • Study design emphasizes that experiments in labs sometimes don't reflect real-world scenarios.
    • Internal validity focuses on unambiguous causal inferences.
    • External validity concerns whether findings apply to different settings and samples.
    • Ecological validity examines whether participants interpret measures as intended.
    • Gaming disorder example (Jeong et al., 2018) shows discordance between self-report and clinical diagnoses in adolescents.
    • Key symptoms aligning with substance-related disorders include preoccupation, withdrawal symptoms, and tolerance.
    • Examples of specific items from the questionnaire used for recovery experiences include: "Last night, I did not think about work at all" (psychological detachment), "Last night, I kicked back and relaxed" (relaxation), "Last night, I did things that challenged me" (mastery), and "Last night, I decided my own schedule" (control).

    Specific Ideas for Increasing External Validity

    • Monitoring daily experiences using ecological momentary assessment, behavioral observations, ambulatory physiological monitoring, and tracking web browsing/phone use.

    Example: Gaming Disorder (Jeong et al., 2018)

    • Data examined discordance between self-report and clinical diagnoses of internet gaming disorder in adolescents.
    • Defined in line with substance-related addictive disorders.
    • Symptoms include preoccupation, withdrawal symptoms, and tolerance.
    • Clinical diagnosis data (positive vs. non-IGD) provided:
      • Positive IGD: 25 participants, 22 non-IGD participants.
      • Negative IGD: 20 participants, 206 non-IGD participants
    • Sensitivity and specificity figures included in the data analysis.

    Example: Gaming Disorder (Jeong et al., 2018) - Continued

    • Data from the analysis shows possible correlations between variables such as anxiety, aggression, and self-esteem in the IGD and Non-IGD groups.
    • P-Values associated with the study's analysis are highlighted to convey the statistical significance of the observed relationships. Examples: P-values for Anxiety, Aggression, Self-esteem, and Familial support are presented. Statistically significant findings were observed for anxiety, aggression, self-esteem and familial support.

    How to Ensure Research is 'Applied'

    • Two examples: studying daily life and brief measures.

    Broad Ideas for Increasing External Validity

    • Sample representativeness ensures the study's participants accurately represent target groups.
    • Topical significance demonstrates the program's impact on outcomes important to populations, practitioners, and decision-makers.
    • Full-cycle research programs encompass diverse phases, from descriptive findings to experimental tests and ecological validity studies.
    • Engaging with the population through knowledge mobilization, translation, and community-engaged research.

    Fostering Quality Participation for Athletes with a Disability (STEP 2)

    • Six key building blocks of quality participation emphasized: autonomy, belongingness, challenge, engagement, mastery, and meaning.
    • Supporting these six blocks with a foundational safety, welcoming, and inclusive physical, program, and social environment are essential for quality participation.

    Brief Measures:

    • Single-item measures for various types of assessment and evaluation are often used to increase practicality and reduce respondent burden, as well as reduce criterion contamination.

    Psychometrics

    • Measurement involves giving numerical values to objects, events, and experiences.
    • Standardization ensures consistency in measurement and scoring.
    • Reliability emphasizes consistency over time and among raters.
    • Internal consistency is a type of reliability.

    Measurement Validity

    • Statistical validity assesses the measure's ability to predict key outcomes and correlate with other relevant measures.
    • Construct validity examines if the measure reflects the concept of interest.
    • External validity indicates if causal relationships can be generalized across measures, subjects, settings, and time.

    Example: Well-being Scale (Su, Tay, & Deinder, 2014)

    • Thriving scale emphasizes feelings of closeness to ideals, satisfaction, and life going well.
    • Key components reflect positive moods and experiences most of the time.

    Demands-Abilities Job Fit

    • Examines the alignment between individual abilities and job demands, covering areas like distributive justice, efficiency climate, emotional demands, emotional fatigue, extrinsic motivation, face-time orientation, and family authenticity.

    Section 2: Interventions

    • Interventions are strategies designed to influence behavior to solve social or practical problems.

    Process and Outcome Evaluation (and Developmental)

    • Process evaluation assesses if the program was implemented as intended.
    • Outcome evaluation measures whether objectives were met.

    Example: Recovery Experiences Questionnaire (Chawla et al., 2020)

    • 207 participants provided work-related recovery experiences over three days, using a specific questionnaire.
    • Specific examples of questions assessed psychological detachment, relaxation, mastery, and control.
    • Other important variables included sleep quality, work engagement, and emotional exhaustion.

    Behavioral economics

    • Blends psychology and economics to understand decision-making inconsistencies.
    • Competing decision systems (system 1-automatic, system 2-controlled) explain human inconsistencies.
    • Bounded rationality suggests that limited resources force people to rely on heuristics (mental shortcuts).
    • Motivations (e.g., impatience, esteem) influence decisions.

    Nudges

    • Nudges influence choices without restricting options or increasing costs.
    • Libertarian paternalism describes how nudges can improve decision-making without coercion.
    • Choice architecture refers to crafting environments to gently guide people. Examples of nudges include "choice-architecture interventions" and "choice-preserving interventions" for influencing decision-making.

    Example: Saving Money (French & Oreopoulos)

    • Forcing 'active' choice about enrolling in a 401(k) program caused 28% increase in enrollment
    • The “save more tomorrow” strategy encourages people to commit to increasing saving in the future. A notable finding by Benartzi and Thaler from 2004.

    Example: Ontario Organ Donation prompts

    • The Ontario organ donor registration system focuses on the long-term benefit, simplifying the registration process. This method uses a "long-term benefit salience" and "simplifies registration" to improve participation rates.

    Evaluation

    • Used to assess the worth of an intervention.
    • Perspectives and research are crucial in evaluation.

    Process Evaluation

    • Evaluating the program's implementation and whether it reached the intended target population.
    • Examining the specific details and activities delivered as planned.

    Outcome Evaluation

    • Assessing how well a program meets its stated objectives.
    • Determining if desired outcomes are achieved for the target population.

    Types of Evidence (in Evaluation)

    • Randomized controlled trials (RCTs) are considered the highest level of evidence. This experimental study allocates participants randomly to either a treatment or a control group, which helps to assess cause and effect.
    • Other types of evidence include systematic reviews, well-designed observational studies, or expert opinions. These types are less rigorous but can still offer helpful information.

    Common Methodological Problems in Randomized Controlled Trials (RCTs)

    • Analysis and design problems, e.g. differences between conditions at baseline, missing or incomplete information on differential attrition at baseline, data analysis errors and/or inconsistencies, use of incorrect analysis methods, or insufficient randomization protocols. Potential sources of bias are also discussed.

    Failures of interventions and why they don't work

    • Sometimes interventions fail due to low validity, poor implementation of replication, or the low effect size of the intervention.
    • Intervention design critical for measuring success, e.g. ecological validity. Examples of failures could include failure to replicate academic fraud, low effect sizes, misinterpretation of interventions, lack of ecological validity within the study designs. The intervention approaches may have failed to create a significant change because of an external factor, such as the intervention being miscommunicated to the target audience or there being insufficient ecological factors for the intervention to work.
