Theory and Science
3
“Science is based on counterfactuals and theoretical
models. Human knowledge is produced by
constructing counterfactuals and theories. Blind
empiricism unguided by a theoretical framework for
interpreting facts leads nowhere.”
Heckman, J. J. 2005. The scientific model of causality. In R. Stolzenberg
(Ed.), Sociological Methodology, Vol. 35, pp. 4–5. Quoted in Ward, A. &
Johnson, P. J., “Addressing confounding errors when using nonexperimental, observational data to make causal claims.” Synthese
163(2008): 419-432.

 The knowledge that transfers between studies is theories
rather than “lumps of data”

Naming & Shaming: Provider report cards, School rankings
 “Produce theories in the form of ‘generative causal
propositions’ which relate mechanisms, context and
outcomes. … simplify all processes down to an essential
core of attributes.”


 Lay theories “as it is expressed in our everyday
language and experience … common-sense or naive
psychology”

Heider, The Psychology of Interpersonal Relations, 1958: 4-7
We can learn from common sense just as we can learn from
folk medicine but is it adequate as science?
Do we need to avoid pseudo-science that looks like science
because it uses sophisticated methods?

Teams: What is a team?
7
A team is“(a) two or more individuals who (b) socially
interact (face-to-face or, increasingly, virtually); (c) possess
one or more common goals; (d) are brought together to
perform organizationally relevant tasks; (e) exhibit
interdependencies with respect to workflow, goals, and
outcomes; (f) have different roles and responsibilities; and
(g) are together embedded in an encompassing
organizational system, with boundaries and linkages to the
broader system context and task environment.”

Sampling Strategies
8
Examples
Sampling Strategies
 Convenience
 Generalizability
 Theory testing
 Maximize variability in key
independent variables
 Arthur Stinchcombe, The
Logic of Social Research.
Chicago: University of
Chicago Press. 2005
 Assertive Community
Treatment teams (NSF)

Full population in Minnesota
 Congestive Heart Failure
(RWJ/INQRI)

Full population in Medical
Centers in VA
 Primary Care Practices
(NPCRDC)

Phase: Qualitative study
comparing practices in
deprived and non-deprived
areas

Measurement

 Customization: Concepts to Measures


Psychological safety in ACT
 I felt that it was easy to ask for a change in the time of a visit.
 I felt that it was easy to ask for a partner to accompany me on a visit.
Take-away
 Are off the shelf instruments adequate for precise measurement?
 Do off the shelf instruments reduce response rates?
 Instruments have to be translated to specific research context
 Measurement validation


Item level – construct validity - convergent and discriminant validity
Team level measures: Intraclass correlation – is there similarity
within teams and differences across teams?

Learn-What
Definition
“The critical and open discussion of
divergent perspectives including task
related facts, data and opposing ideas.”
“A shared belief that the team is safe for
interpersonal risk taking.”
Involvement in activities that identify the
best practices that are currently available.

Next Steps
15
 Causal modeling
 Using contextual measures as instruments to do causal
modeling
 Change over time
 Will have three waves of data spaced at six month intervals
linked with quarterly evaluations of client outcomes

Conclusion
16
 Methods are conditional on theory


Methods cannot save inadequate conceptualization
With good theory, methods are straightforward (but can be difficult)
 Sampling for theory testing is different than sampling for
generalizability
 Instruments need to be customized to context for precise
measurement and good response rates
 Many phenomena are nested


Team members or clients are nested within teams which are nested
within sponsors
Concepts have to be validated at the appropriate theoretical level
(intraclass correlations)
