How do you encourage culturally-sensitive research?

spend time immersing yourself directly in the culture of the group -engage scholars and community representatives in formulation of research problem and all stages -have group members in research designs and instruments -don't assume instruments are good for this minority group

numerical data vs. text data

#'s and statistics vs words and descriptions

What is content analysis?

Content Analysis focuses on what was said

external validity of a research design

-Can we generalize findings to another population

Threats to internal validity of a research design

-History -Maturation -Instrumentation -Testing (reactive) -Statistical Regression -Selection Bias -Experimental attrition (mortality) -Diffusion or Imitation of treatment

How do you collect data in qualitative work?

-Interviewing = unstructured, semi or structured -Observation = direct or essentially direct via video -Written documents = work with words and visual data, not numbers

Name and explain the 3 basic criteria for the determination of causation

-Time-the cause precedes the effect in time - Covariance-two variables (IV & DV) are empirically correlated with each other -No other explanations- (IV and DV are exclusively involved) the observed empirical correlation cannot be explained away as the result of the influence of some third variable that causes the two under consideration

Know how to minimize threats to external validity

-Unrepresentice samples -Multiple-Treatment Interference -Interaction of Selection and Treatment -Reactive Settings -Researcher Bias

How do you identify problems and establish goals with clients?

-You prioritze issues and choose which ones to address first -they are precise, and observable and realistic -set long term goals with intermediate goals

What information needs to be included in an informed consent?

-describes involvement, benefits, risks, extent of confidentiality, expenses, compensation, explains opportunity to chose, and contact people for additional questions

internal validity of a research design

-is X the cause of Y?

Cross-sectional

-one point in time

What are identifiers?

Anything that can give the person's identity away

univariate statistics

Continuous: -mean, median, mode, range, histogram Categorical: -frequency, bar graph, histogram, pie chart

baseline vs intervention phase

Baseline: an observation, no intervention Intervention: formally planned and systematically executed set of practioner behaviors that are engaged in order to change the target problem

What is the difference between retrospective and concurrent baseline?

Concurrent: data about the target behaviors are collected during the assessment phase of therapy prior to the intervention Retrospective: data about target behaviors is reconstructed from memory or records

What did the Tuskegee experiment do right?

Human behavior, IRB established, encouraged community members

How do you use the clinical research model? What are the steps?

Identify problems Establish goals Choose single case design Establish baseline Introduce treatment with intervention Assess treatment effects

What is the clinical research model?

Identifying problems with assessment

How do you select a sample in qualitative work?

Judgement and snowball sampling

single subject design choices, how are they different

Single case True experimental Non experimental (quasi)

What are the benefits of qualitative research?

Strengths = depth and detail, openness, understanding world view, avoids pre-judgements Weakness = fewer respondents, less easily generalized, difficult to aggregate data, particpation can change social situations, dependent upon researcher's personal skills

What are the differences between qualitative and quantitative methods?

The differences are the researcher's underlying strategies

Explain the principles of voluntary participation and no harm to participants

Voluntary: choosing to participate and that they can withdraw at any time

When is SPSS appropriate for data analysis?

When organizing and analyzing data, presenting data through graphs

When is it best to use a qualitative approach?

With observation, descriptive, explanatory, exploratory and not easily reduced to numbers

Why would you create a new variable from existing ones

You may want to examine different aspects of the data that require you to re-code the orginal data

existing data

already around

original data

collected for the first time

bivariate statistics

comparing 2 variables -correlations, t-tests, chi-square tests

Structured observation

data collection where a trained observer records the interactions of others in a specific place using detailed procedures and measures.

What is the difference between data collection and data sources?

data collection- the method for gathering information data sources- where the information comes from -from survey research, records, machines

coding as it relates to data analysis

deriving some meaning from observations that have been made during the research process

secondary data

existing data collection gathering previously collected information

Longitudinal

follow through time

What is a pie chart good for displaying?

for categorical, when you have multiple categories with distribution

What is HIPAA?

health insurance portability and accountability act -provides federal health information privacy, must have signed release

intervention fidelity

how true to the intervention, make sure its the intervention and nothing else making the change

frequency, duration, and magnitude

in structured observations frequency- the number of times a behavior occurs duration-the amount of time the behavior occurs magnitude- the intensity of the observed behavior

Second hand data

information about subject comes from someone else

What is an IRB?

institutional review board

multivariate statistics

multiple regression, logistic regression

surveys

original data could be first or second hand

What is PHI?

protected health information

Quasi-Experimental vs. True Experimental Designs

quasi- a study that evaluates an intervention group versus a comparison group but where participants are NOT randomly assigned to groups true- a study that randomly assigns participants to an experimental group and a control group

How to minimize drop-out of research participants

reimbursement, avoid intervention disappointing or frustration participants, utilize tracking

What aspects of the research protocol do IRB members review and approve?

risks are minimized and reasonable in relation to benefits and the importance of anticipated knowledge -selection f subjects is equitable -informed consent will be obtained and documented -safeguards in place to protect vulnerable subjects -adequate plans are in place for monitoring data for safety -privacy will be protected and confidentiality maintained.

First hand data

straight from the individual (subject)

Response rate and how to calculate

the proportion of a sample that completes and returns a questionnaire or agrees to be interviewed interviews have higher response rate than questionnaires

What are the advantages of questionnaires, interviews and focus groups?

they are survey research very detailed and thorough questionnaires- quick and inexpensive, geographically diverse, no interviewer bias interviews- flexible

When does measurement happen in single subject design?

throughout the entire experiment

what is survey research?

using questionnaires, interviews, and focus groups
