Human behavior takes place in different contexts (e.g., organizations, schools, families, sports teams, and communities) whose properties (e.g., climate, culture, cohesion, leadership, communication networks, and structure) influence human behavior. To estimate this influence, researchers need appropriate methods that avoid the problems associated with the application of standard Ordinary Least Square (OLS) regression. Multilevel modeling methods offer researchers a way to estimate the aforementioned influence. These methods take into account that the variables involved reside at different levels. For instance, in the relationship between work unit climate and employee job satisfaction, the former variable resides at the work unit level (level 2) whereas the latter resides at the individual one (level 1). Moreover, multilevel modeling methods also take into account that the data analyzed to estimate this type of relationships have a nested structure in which individuals (e.g., employees) are nested into collectives (e.g., work units). Finally, these methods decompose variance into between-group and within-group components and allow researchers to model variability at the between and within levels. Specifically, multilevel modeling methods allow researchers to test hypotheses that involve, among others: 1. A relationship between a higher-level predictor (e.g., work unit climate) and a lower-level outcome (e.g., employee job satisfaction); a so-called “direct cross-level effect”, and 2. An influence of a higher-level moderator (e.g., work unit climate) on an individual level relationship (e.g., the relationship between employee job stress and job satisfaction); a so-called “cross-level interaction”. Multilevel modeling methods can also be used to test more complex models involving mediation (e.g., 2-2-1, 2-1-1, or 1-1-1 models, depending on whether the antecedent and the mediator are level 1 or level 2 variables) and moderated mediation. We show how to test these models by presenting examples with real data and the corresponding SPSS syntax that readers can use to practice.

Positive leadership is a major domain of positive organizational scholarship. The adjective “positive” applies to any leader behavioral pattern (style) that creates the conditions by which organizational members can self-actualize, grow, and flourish at work. Some examples of style are authentic, transformational, servant, ethical, leader–member exchange, identity leadership, and the leader character model. Despite the myriad constructive outcomes that relate to said positive leadership styles, positive leadership it is not without its critics. The three main criticisms are that (a) the field is fragmented and might suffer from conceptual redundancy, (b) extant research focuses on the individual level of analysis and neglects reciprocal and cross-level effects, and (c) positive leadership is naïve and not useful for managing organizations. Our multilevel model of positive leadership in organizations proposes that leaders rely on internalization and integration to incorporate meaningful life experiences and functional social norms into their core self. Further, through self-awareness and introspection, leaders discover and exercise their latent character strengths. In turn, positive leaders influence followers through exemplary role modeling and in turn followers validate leaders by adopting their attributes and self-determined behaviors. At the team level of analysis, positive team leaders elevate workgroups into teams by four mechanisms that shape a shared “sense of we,” and workgroup members legitimize positive leaders by granting them a leader role identity and assuming follower role identities. Finally, at the organizational level, organizational leaders can shape a virtuous culture by anchoring it on universal virtues and through corporate social responsibility actions improve their context. Alternatively, organizations can shape a virtuous culture through organizational learning.
