The authors introduce a framework for organizing conceptualizations of social identity along four dimensions: perception of the intergroup context, in-group attraction, interdependency beliefs, and depersonalization. The authors suggest that the extent to which each dimension is evoked or assessed will have an impact on the consequences attributed to social identity. Two studies test hypotheses derived from the framework and investigate the psychometric properties of several scales. In Study 1, participants completed four social identity scales, two group cohesion scales, and a measure of allocentrism. Interscale commonalities were tested through a secondary factor analysis, and the scales and secondary factors were used to predict in-group pride and intergroup bias. Study 2 included additional predictors (interdependency, conflict, competition) and outcome measures (in-group and out-group evaluations, perceived group homogeneity, and the twenty statements test). Consistent with predictions, two types of social identity were empirically extracted and were differentially related to the outcome measures. Theoretical and empirical implications are discussed.

A theoretical framework to account for Whites' attitudes toward Asian Americans was developed and tested in 3 studies. An Attitude Toward Asians (ATA) scale was developed and found to be valid and reliable. Consistent with the framework, a negative factor and a positive factor were found to underlie attitudes toward Asian Americans. As expected, negative attitudes were shown to stem from both negative and positive instrumental attributes, whereas positive attitudes stemmed from positive instrumental and noninstrumental attributes. Predictions regarding emotional reactions to Asian Americans and attitude ambivalence were supported. Attitudes toward Asian Americans were also shown to influence judgments of African Americans. Implications and future research directions are discussed.

BackgroundProper implementation of evidence-based interventions is necessary for their full impact to be realized. However, the majority of research to date has overlooked facilitators and barriers existing outside the boundaries of the implementing organization(s). Better understanding and measurement of the external implementation context would be particularly beneficial in light of complex health interventions that extend into and interact with the larger environment they are embedded within. We conducted a integrative systematic literature review to identify external context constructs likely to impact implementation of complex evidence-based interventions.MethodsThe review process was iterative due to our goal to inductively develop the identified constructs. Data collection occurred in four primary stages: (1) an initial set of key literature across disciplines was identified and used to inform (2) journal and (3) author searches that, in turn, informed the design of the final (4) database search. Additionally, (5) we conducted citation searches of relevant literature reviews identified in each stage. We carried out an inductive thematic content analysis with the goal of developing homogenous, well-defined, and mutually exclusive categories.ResultsWe identified eight external context constructs: (1) professional influences, (2) political support, (3) social climate, (4) local infrastructure, (5) policy and legal climate, (6) relational climate, (7) target population, and (8) funding and economic climate.ConclusionsThis is the first study to our knowledge to use a systematic review process to identify empirically observed external context factors documented to impact implementation. Comparison with four widely-utilized implementation frameworks supports the exhaustiveness of our review process. Future work should focus on the development of more stringent operationalization and measurement of these external constructs.Electronic supplementary materialThe online version of this article (10.1186/s12913-018-3046-5) contains supplementary material, which is available to authorized users.
