#1
Which of the following is an example of a qualitative research method?
Interview
ExplanationQualitative research methods involve exploring subjective experiences and perceptions, making interviews a common technique.
#2
Which of the following is a disadvantage of using self-report measures in health psychology research?
They can suffer from social desirability bias
ExplanationSelf-report measures in health psychology may be influenced by social desirability bias, as participants may respond in ways they believe are socially acceptable.
#3
What is the primary aim of correlation analysis in health psychology research?
To identify the strength of relationships
ExplanationCorrelation analysis assesses the degree of association between variables, revealing the strength and direction of relationships in health psychology.
#4
In health psychology, what does the acronym 'RCT' stand for?
Randomized Controlled Trial
ExplanationRCTs are experimental studies where participants are randomly assigned to either the treatment or control group, ensuring unbiased comparisons.
#5
Which statistical test is most appropriate for comparing means of three or more groups in health psychology research?
ANOVA
ExplanationANOVA (Analysis of Variance) is suitable for comparing means across multiple groups, providing insights into group differences in health psychology research.
#6
What is a confounding variable in experimental research?
A variable that affects both the independent and dependent variables
ExplanationConfounding variables are extraneous factors that can impact both the independent and dependent variables, potentially leading to inaccurate conclusions in experimental research.
#7
Which of the following best describes the purpose of meta-analysis in health psychology research?
To combine results from multiple studies to increase statistical power
ExplanationMeta-analysis aggregates findings from various studies, enhancing statistical power and providing a more comprehensive understanding of a particular phenomenon in health psychology research.
#8
What is the difference between internal validity and external validity in research?
Internal validity refers to the extent to which the study design eliminates confounding variables, while external validity refers to the extent to which findings can be generalized
ExplanationInternal validity ensures that study design minimizes confounding variables, while external validity assesses the generalizability of findings to broader populations or contexts in research.
#9
Which of the following is an example of a longitudinal study in health psychology research?
A study following a group of individuals over several years to assess changes in mental health
ExplanationLongitudinal studies track individuals over time, allowing researchers to observe changes in mental health or other variables in health psychology.
#10
What does 'p-value' represent in hypothesis testing?
Probability of obtaining the observed results by chance
ExplanationThe p-value indicates the likelihood of obtaining observed results purely by chance, helping researchers assess the significance of their findings in hypothesis testing.
#11
In health psychology research, what is meant by the term 'effect size'?
The strength of the relationship between variables
ExplanationEffect size quantifies the strength of relationships between variables in health psychology research, providing a standardized measure of the magnitude of observed effects.
#12
What is the purpose of random assignment in experimental research?
To ensure that the experimental group and control group are equivalent
ExplanationRandom assignment minimizes bias by ensuring that participants in the experimental and control groups are comparable, enhancing the internal validity of experimental research.
#13
What statistical test is appropriate for examining the relationship between two continuous variables in health psychology research?
Pearson correlation
ExplanationPearson correlation is used to assess the strength and direction of the linear relationship between two continuous variables in health psychology research.
#14
In health psychology research, what is the purpose of a pilot study?
To test the feasibility of the research design and procedures
ExplanationPilot studies assess the feasibility of research design and procedures, allowing researchers to identify and address potential challenges before conducting the full study in health psychology research.
#15
Which of the following best describes a quasi-experimental design?
A design that manipulates the independent variable but does not control extraneous variables
ExplanationQuasi-experimental designs manipulate the independent variable but lack full control over extraneous variables, making them less rigorous than true experimental designs in health psychology research.
#16
In health psychology research, what does 'qualitative data' refer to?
Data that consists of words, descriptions, and images
ExplanationQualitative data in health psychology research consists of non-numeric information, including words, descriptions, and images, allowing for a rich understanding of subjective experiences.
