CHAPTER IIIRESEARCH METHODS RESEARCH DESIGN POPULATION SAMPLING PLAN PSYCHOMETRIC ANALYSES
Research Design • Quantitative Non-Experimental • Comparative (exploratory) • Explore differences • Correlational (explanatory) • Determine which explanations are best. • On-Line survey • Five parts completed by the respondents
Population • Estimated Target Population • Miami-Dade 4480 • Broward 4200 • Palm Beach 1960 • Total 10640
Accessible Population Source of CFT Members • Professional Contacts 50 • Hospital Web Sites • Physicians 15 • Nurses 20 • Other CFT Members 20 • Professional Associations259 Total 364
Sampling Plan • Purposive and Snowball Sampling Plan • Initial purposive sample included the accessible population • Estimated Sample (see table 3-4) • Initial purposive sample = 364 • Snowball sampling = 1043 CFT • Final data producing sample = 181 • Response rate = 17.4%
S E T T I N G S Palm Beach = 7 Broward = 15 Miami-Dade = 16
Data Producing Sample • Step 1 (actual) • Email sent to initial purposive sample = 241 • Step 2 (estimated) • Snowball sample email sent to 441 • Step 3 (estimated) • Snowball sample email sent to 690 • Produced 206 responses (actual) • Produced 185 valid responses (valid response rate of 27%)
Instrumentation • Part 1: Actual Similarity-Dissimilarity • 10 items, demographics • Part 2: Perceived Dissimilarity • 6 item scale, 3 subscales • Part 3: Perceived Group Openness to Diversity • 6 item scale, 3 subscales • Part 4: Team Cohesion • 5 items scale, unidimensional • Part 5: Team Outcome Effectiveness • 26 item, 5 subscales
Procedures • Obtained permission to use scales • Designed online survey • IRB approval • Invitation e-mails sent BCC • Voluntary participation • Responses anonymous • 10-15 minutes to complete • No IP addresses tracked • Data encryption
Evaluation of Strengths and Weaknesses • Internal Validity Strength • Good estimates of reliability for scales • Ecological strength • Rigorous statistical procedures Weaknesses • Small sample size • Non-experimental, (lack of randomization, controls)
Evaluation of Strengths and Weaknesses • External Validity Strengths • Included the entire accessible population • Data collection in natural setting Weaknesses • Non Random Snowball Sampling introduces sampling bias
Methods of Data Analysis • Research Question 1 • Descriptive statistics • Research Question 2 • Independent t-tests and ANOVA with Tukey’s post hoc comparison compared differences according to actual similarity-dissimilarity • Research Question 3 • Chi square and ANOVA with Tukey’s post hoc comparison compared differences according to hospital organizational characteristics
Hypothesis Testing • Explanatory (Correlational) Design • Hierarchical Multiple Regression Method • Step 1: Eta correlations for categorical variables • Step 2: If significant, dummy variables created Step 3: Pearson r for significant and trend dummy variables, ratio variables, and interval variables. • Step 4: Hierarchical regression – entered from strongest to weakest
