  2. CHAPTER IINTRODUCTION TO THE STUDY Introduction and Background Definitions of Terms Purpose Justification

  3. Introduction and Background • Embedded Cross-Functional Teams • Homogenous (similarity) • Heterogeneous (dissimilarity) • Diversity-Demographics, Occupations • Complex Hospital Organizations • Regulatory Pressure • Competition • Location • Classification

  4. Definitions of Terms • Cross functional team • Work groups, cross-disciplinary, interdisciplinary, multi-disciplinary teams • Hospital Characteristics • Geographic location, tax status, legal classification, and the number of licensed beds • Actual Similarity-Dissimilarity • age, gender, ethnicity, race, occupational title, professional practice areas, practice experience in years, tenure in current hospital

  5. Definitions of Terms • Perceived Dissimilarities • Visible, values, and informational dissimilarities • Perceived Group Openness to Diversity • Visible, values, and informational • Team Cohesion • Feelings about acceptance by fellow team members • Team Outcome Effectiveness • Goals, customers, timeliness, quality, and productivity.

  6. Definitions of Terms • Organizational performance • Average Length of Stay (LOS) (risk adjusted days a patient stays in hospital) • JCAHO survey results for the Management of the Environment of Care • Percent score • Percentile score

  7. Study Purposes • Exploratory (comparative) - differences according to • Actual similarity-dissimilarity • Hospital characteristics • Explanatory (correlational) - explain relationships between • Actual and perceived similarity-dissimilarity, openness to diversity, cohesion, effectiveness, organizational characteristics, and organizational performance

  8. Definition of Terms Tri-County Hospitals CFTs Hospital Characteristics Similarity- Dissimilarity Diversity Effectiveness Cohesion Performance

  9. Justification • Previous Studies Limited in Scope • Growing Issues in Healthcare • Uninsured, HMO’s, Costs, Competition • This Study • Addresses Important Concepts • Increasing Diversity……Effectiveness…Performance • Researchable, Can be Tested, Measurable

  14. CHAPTER IIIRESEARCH METHODS RESEARCH DESIGN POPULATION SAMPLING PLAN PSYCHOMETRIC ANALYSES

  15. 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

  16. Population • Estimated Target Population • Miami-Dade 4480 • Broward 4200 • Palm Beach 1960 • Total 10640

  17. Accessible Population Source of CFT Members • Professional Contacts 50 • Hospital Web Sites • Physicians 15 • Nurses 20 • Other CFT Members 20 • Professional Associations259 Total 364

  18. 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%

  19. S E T T I N G S Palm Beach = 7 Broward = 15 Miami-Dade = 16

  20. 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%)

  21. 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

  22. 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

  23. 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)

  24. 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

  25. 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

  26. 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
