Meta-analysis of correlates of provider behavior in medical encounters.

This article summarizes the results of 41 independent studies containing correlates of objectively measured provider behaviors in medical encounters. Provider behaviors were grouped a priori into the process categories of information giving, questions, competence, partnership building, and socioemotional behavior. Total amount of communication was also included. All correlations between variables within these categories and external variables (patient outcome variables or patient and provider background variables) were extracted. The most frequently occurring outcome variables were satisfaction, recall, and compliance, and the most frequently occurring background variables were the patients gender, age, and social class. Average correlations and combined significance levels were calculated for each combination of process category and external variable. Results showed significant relations of small to moderate average magnitude between these external variables and almost all of the provider behavior categories. A theory of provider-patient reciprocation is proposed to account for the pattern of results.

Patient-physician communication: A descriptive summary of the literature

Abstract This paper summarizes the results of 61 independent studies containing descriptive variables from objectively measured medical encounters. Over 200 unique patient and provider variables were identified and grouped a priori, through a process of consensual validation, into six broad categories of communication process variables: information-giving, information-seeking, partnership-building, social conversation, positive talk and negative talk. Length of medical visit and proportionate contribution of each speaker were abstracted. In addition each study was coded for 47 study attributes including characteristics of the sample, study design and methodology. Study results fall in three broad areas: (1) characteristics of the studies are presented based on the coded attributes; (2) communication profiles of patient and physician interaction are constructed by averaging the data over studies; and (3) comparisons of communication behavior across studies are presented by common sample and setting characteristics.

Network Theory and Small Groups

This article describes the network approach to small groups. First, the core constructs that compose social network research are explained. The primary theories that provide the intellectual underpinning of the network approach are described, including theories of self-interest, theories of social exchange or dependency, theories of mutual or collective interest, cognitive theories, and theories of homophily. Highlights of the empirical work examining the internal and external networks of small groups is summarized. Finally, the primary challenges researchers face when applying the network perspective to small groups, and the primary benefits that can accrue to researchers who adopt that perspective, are enumerated.

The Coevolution of Networks and Political Attitudes

How do attitudes and social affiliations coevolve? A long stream of research has focused on the relationship between attitudes and social affiliations. However, in most of this research the causal relationship between views and affiliations is difficult to discern definitively: Do people influence each others views so that they converge over time or do they primarily affiliate (by choice or happenstance) with those of similar views? Here we use longitudinal attitudinal and whole network data collected at critical times (notably, at the inception of the system) to identify robustly the determinants of attitudes and affiliations. We find significant conformity tendencies: Individuals shift their political views toward the political views of their associates. This conformity is driven by social ties rather than task ties. We also find that political views are notably unimportant as a driver for the formation of relationships.

Contextualizing Patterns of Work Group Interaction: Toward a Nested Theory of Structuration

The focus of this article is the patterns of interaction that arise within work groups, and how organizational and institutional factors play a role in shaping these patterns. Based on an ethnographic study of groups across three national contexts, we describe the variation in patterns of interaction that we observed. We further suggest how different patterns of interaction form mutually reinforcing systems with aspects of the organizational context. In addition, we suggest how these mutually reinforcing systems are perpetuated by aspects of the broader institutional context. Our findings point toward a nested theory of structuration, expanding structuration theory to multiple levels simultaneously. In turn our findings have theoretical and practical implications for better understanding and managing interaction patterns among group members.

Networks and Political Attitudes: Structure, Influence, and Co-evolution

How do political views and social affiliations co-evolve? A long stream of research has focused on the relationship between political views and social affiliations, however, it is typically difficult to discern the causal relationship between views and affiliations. Here we use longitudinal attitudinal and whole network data collected at critical times (notably, at the inception of the system) to pinpoint and specify the determinants of attitudes and affiliations. We find significant conformity tendencies: individuals shift their political views toward the political views of their associates. This conformity is driven by social ties rather than task ties. We also find that, while individuals tend to associate with similar others, political views are notably less a basis for associational choices than demographic and institutional factors.
