From the interpersonal to the international: understanding commitment to the "war on terror"

Applying constructs from the investment model used traditionally to understand interpersonal commitment, the present investigation seeks to elucidate social cognitive antecedents of commitment to the war on terror waged by the United States. In Study 1, satisfaction with, investments in, and alternatives to the war on terror predict levels of commitment to the war beyond several important control variables. In Study 2, levels of satisfaction with, investments in, and alternatives to the war are experimentally manipulated. The highest levels of commitment to the war are observed among participants exposed to a high satisfaction, high investment, and low alternatives scenario, and the lowest levels are among those exposed to a low satisfaction, low investment, and high alternatives scenario. These results support broadening the targets of commitment normally considered within the context of the investment model and suggest applying relational models to understanding broader societal concerns.     

Attachment and the investment model: Predictors of relationship commitment,maintenance, and persistence

This research examines adult attachment and the investment model. Study 1 tests anxiety and avoidance predicting romantic relationship commitment, mediated by satisfaction, alternatives, and investments. Additional studies added outcomes of relationship maintenance (Study 2) and persistence (Study 3). In all 3 studies, satisfaction, alternatives, and investments mediated the associations between anxiety and avoidance and relationship commitment. A direct effect of avoidance on commitment remained. The investment model variables mediated the effect of anxiety and avoidance on accommodation and willingness to sacrifice (Study 2) and relationship persistence (Study 3). Direct effects remained for avoidance on accommodation and anxiety on persistence. The mediated model was supported for men and women, proximal and long‐distance relationships, and college student and community samples.     

Investigating the interface of the investment model and adult attachment theory

We examined whether the extent to which individuals accord importance to components of the investment model varies by attachment. In Study 1, rewards and costs in a hypothetical relationship were experimentally manipulated, and participants (single and dating undergraduates) reported perceptions of rewards, costs, and satisfaction. In Study 2, investments and alternative quality were manipulated, and participants reported perceptions of investments, alternatives, satisfaction, and commitment. Study 1 revealed that relative to others, individuals high in both anxiety and avoidance (i.e., fearful) accord less weight to rewards when determining satisfaction. Study 2 revealed that relative to others, individuals low in anxiety and high in avoidance (i.e., dismissing) accord more weight to investments and alternatives, and less weight to satisfaction when determining commitment.

Commitment Predictors: Long‐Distance Versus Geographically Close Relationships

In this web‐based study, the authors examined long‐distance relationships (LDRs) and geographically close relationships (GCRs). Two hierarchical multiple regressions (N = 138) indicated that attachment predicted LDR and GCR commitment in Step 1. Final equations indicated that high satisfaction and investments predicted LDR commitment, whereas low attachment avoidance, low cooperative caregiving, high satisfaction, and low alternatives predicted GCR commitment. The pattern of predictors differed for LDRs versus GCRs.     

Social interdependence in close relationships: The actor–partner‐interdependence–investment model (API‐IM)

This article introduces the actor–partner‐interdependence–investment model (API‐IM) that was developed to add a dyadic perspective to Rusbult's investment model. The API‐IM is based on interdependence theoretical assumptions and the actor–partner interdependence model. Two studies were conducted to investigate the reliability of the API‐IM. Relationship satisfaction, investment size, quality of alternatives, and relationship commitment were assessed at both partners of 77 (Study 1) and 162 (Study 2) married and unmarried heterosexual couples. Path analyses that applied a structural equation modeling framework revealed a dyadic model that significantly predicts women's and men's commitment by actor effects of satisfaction, investments, and alternatives, and partner effects of satisfaction. Actor and partner effects of satisfaction were significantly moderated by relationship duration and marital status. Marital status also significantly moderated the actor effect of alternatives. The API‐IM supports the concept of social interdependence in close relationships, and it is discussed as a sound dyadic extension of the investment model.

Commitment to the GLBT community: an investment model analysis of its antecedents and consequences

The present research applied the investment model to the study of how gay, lesbian, bisexual, and transgender (GLBT) persons become committed to the broader community of sexual minorities. In addition, the present research examined the potential consequences associated with such commitment. In Study 1, satisfaction, investments, and alternatives each uniquely predicted an individual's commitment to the GLBT community. In Study 2, commitment to the GLBT community predicted higher levels of GLBT identification and stronger intentions to be involved in the community in the future. This research has important implications for understanding the factors that promote strong commitment to minority communities and how such commitment may play a vital role in facilitating social and political change for lower status groups.     

The role of moral commitment within the Investment Model

The Investment Model (Rusbult, 1980) defines general commitment as a long‐term orientation towards relationship maintenance and feelings of psychological attachment, influenced by satisfaction, quality of alternatives and intrinsic/extrinsic investments. We suggest the importance of additionally assessing moral commitment, defined by an intrapersonal predisposition to remain in the relationship (Johnson, 1991). We argue moral commitment's association to perceived intrinsic investments acting as internal barriers influencing general commitment and promoting relationship maintenance. A correlational study resorting to structural equation modelling showed that moral commitment predicted intrinsic investments, which in turn predicted general commitment (Model 1). No direct paths emerged from moral commitment to satisfaction or quality of alternatives (Model 2), nor it emerged as a fourth direct predictor of general commitment (Model 3). Results are discussed under relationships maintenance and dissolution frameworks.     

An Assessment of Romantic Commitment Among Black and White Dating Couples1

The purpose of this study was to test the utility of the Investment Model (Rusbult, 1980) of romantic commitment for black and white dating couples. Twenty black and 20 white college dating couples completed questionnaires measuring the Investment Model components and additional variables. According to the Investment Model, the level of romantic commitment is positively related to relationship satisfaction and positively related to the magnitude of personal investments, but negatively related to the availability of romantic alternatives. We expected the romantic commitment of black couples to differ from that of white couples due to the shortage of available black male partners. The only racial differences to emerge, however, were found in a Race8 Gender interaction: Commitment increased with an increase in satisfaction for white males, but not black males. Gender differences indicated that the Investment Model provided a better account of the commitment of females. We also examined the role of two other factors in the prediction of commitment: perceived physical attractiveness of the partner and concern about AIDS. Both factors were significantly related to commitment for males, but not females, and neither of these factors demonstrated racial differences.     

Victim’s innocence, social categorization, and the threat to the belief in a just world

This research studies people’s reactions to the suffering of victims, examining the hypothesis of the belief in a just world (BJW) (Lerner, 1980) according to which the awareness of innocent victims threatens people’s BJW, and extending the scope of BJW theory to intergroup contexts. An implicit measure of the threat to the BJW (Hafer, 2000a) is used in this research. After participants viewed a videotaped film containing the victimization story they performed an emotional modified Stroop task. Study 1 examined the threat to the BJW as function of the innocence of the victim at an interpersonal level of analysis. Results show that only the innocent victim threatens the observer’s BJW. Study 2 examined the threat to the BJW as function of the victim’s group and of the victim’s innocence. Results show that an ingroup victim threatens the participant’s BJW more than a victim belonging to an outgroup.     

The relationship between objective and perceived fit with academic major, adaptability, and major-related outcomes

This study examined the effects of fit with college major on major commitment, GPA, college satisfaction, and changing one’s major. We further examined how individual adaptability may moderate the importance of fit on these outcomes. College students (N = 198; 160 women and 38 men; mean age = 19.14 years) completed an interest inventory used to assess objective fit with major, and also indicated their perceived fit with major. Results revealed little correlation between perceived fit and objective fit, with differential relationships to these outcomes. Perceived fit showed stronger positive correlations with affective major commitment and academic self-efficacy than did objective fit. Regarding the moderating role of adaptability, individuals higher in adaptability reported higher institutional satisfaction when there was lower perceived fit. Adaptability also had a main effect on major-related outcomes above and beyond the effects of fit. Practical and theoretical implications of these results are discussed.     

Best friends forever?: High school best friendships and the transition to college

The transition from high school to college is an important phase for adolescents in social as well as academic aspects. This study examined the changes that occur in high school best friendships during the first year of college. Results revealed that during the first year in college high school best friendships declined in satisfaction, commitment, rewards, and investments. During this period there was also an increase in costs and alternatives to best friend relationships. Proximity did not influence the friendships; however, level of communication did moderate friendship deterioration. Furthermore, individuals who continued their best friendship reported engaging in more maintenance behaviors of positivity, supportiveness, self‐disclosure, and interaction than individuals who reported a change in the relationship to close or casual friendship. Maintaining the best friendship also appeared to buffer adolescents from social loneliness. The results are discussed in terms of the implications of transitions on adolescent friendships.     

The influence of fear of happiness beliefs on responses to the satisfaction with life scale

General life satisfaction scales are widely used to examine the degree to which people are satisfied with their lives. Previous research indicates that part of the variability in life satisfaction scores does not genuinely reflect individuals’ life conditions, and that there are factors biasing people’s responses to these scales. The present study provided initial evidence showing that the fear of happiness (a belief that happiness may have negative consequences) influenced people’s responses to the items of a life satisfaction scale in an Iranian university student sample. Implications of the results are discussed.     

Intuitive theories of group types and relational principles

Three studies investigated perceivers’ beliefs about the principles by which different kinds of social groups govern interactions among group members. In Study 1, participants rated a sample of 20 groups on a set of group properties, including measures of relational principles used within groups. Results showed that people believe that interactions in different types of groups are governed by different blends of relational principles unique for each type of group. Study 2 experimentally demonstrated that perceivers could use minimal group property characteristics of different types of groups (i.e., extent of group member interaction, group size, duration, and permeability) to make inferences about the relational principles used in different types of groups. Study 3 demonstrated that relational style information influences people’s judgments of a group’s entitativity and collective responsibility.     

Failing to commit: Maximizers avoid commitment in a way that contributes to reduced satisfaction

Past research suggests that individuals who approach decisions with the goal of maximizing, or selecting the best possible option, show less satisfaction with their choices than those with the goal of satisficing, or selecting the first “good enough” option. The present investigation examines whether this difference in choice satisfaction stems from a difference in willingness to commit to one’s choices. We argue that maximizers are reticent to commit to their choices and that this reticence robs them of the dissonance reduction processes that leave people satisfied. In Study 1, maximizers reported a stronger preference than satisficers for retaining the possibility to revise choices, both when reporting preferences in their own life and when choosing between options in a hypothetical situation. In Study 2, satisficers showed evidence of classic dissonance reduction after making a choice - they offered higher ratings of a chosen poster and lower ratings of the rejected alternatives, relative to baseline. However, maximizers were less likely to change their impressions of the posters after their choice, leaving them less satisfied with their selected poster. These results provide valuable insight into post-decision processes that decrease maximizers’ satisfaction with their decisions.     

Predicting College Student Satisfaction, Commitment, and Attrition from Investment Model Constructs

In a medium-sized college, 174 undergraduates evaluated the rewards, costs, alternatives, and investments associated with their enrollment. These investment model variables (Rusbult, 1980a) were significantly related to the students'satisfaction with the college, their commitment to remain enrolled, and their subsequent enrollment behavior. Linear and logistic regression results supported many, but not all, investment model predictions concerning the relationships between model constructs. Investment model variables were found to have greater validity than integration model variables (Tinto, 1975) in predicting institutional commitment and enrollment behavior. Implications for theory and practice are discussed.     

The Effects of Commitment to Performance Goals on Effort1

The laboratory experiments were designed to examine the effects of commitment to a performance goal on the level of effort exerted to achieve the goal. In both experiments, college students worked on two memorization tasks and, after receiving performance feedback on the first task, commitment to either an easy or a more difficult goal for the second task was varied. In the first experiment, goal commitment was manipulated either by giving the students perceived choice over setting their goal or by assigning them to one of the two goal levels. In the second experiment, goal commitment was manipulated by publicly identifying students' goals or by keeping the goals private. To assess effort, participants were allowed to spend as little or as much time as they desired studying for the second task. In both experiments, the commitment manipulations (high choice or public identification) led to significantly greater persistence in studying, regardless of the goal level. In addition, high-commitment subjects tended to be more successful in reaching their goals than low-commitment subjects. These experiments suggest that commitment to a goal has motivational properties that prompt an increase in effort.     

Spoilt for choice: The role of counterfactual thinking in the excess choice and reversibility paradoxes

Contrary to popular belief many choice options and the ability to reverse one's initial choice are sometimes associated with decreased chooser satisfaction. Two studies investigated the role of counterfactual thinking in explaining these paradoxes. Participants chose drawing implements from either a limited (6) or extensive (24) choice set (Study 1), or an expected reversible/non-reversible selection (Study 2). Following a drawing task, satisfaction with their chosen implement was rated under either high or low cognitive load to manipulate the availability of counterfactual alternatives. In Study 1 satisfaction was higher with limited vs. extensive choice under low load. The number of counterfactuals generated mediated this effect. Under high load the pattern was reversed. Participants in Study 2 generated more counterfactuals when reversibility was expected under low but not high load and this partially mediated the impact of expected reversibility on revealed satisfaction. Implications for theoretical understanding of these paradoxes are discussed.     

Commitment in relationships: An updated meta‐analysis of the Investment Model

This article provides a systematic review and updated meta‐analysis of the extant literature on Rusbult's Investment Model of Commitment. This meta‐analysis aimed to determine the strength of the associations between commitment and its antecedents and to investigate potential moderators of these associations. This meta‐analysis included 50,427 participants from 202 independent samples (collected between 1980 and early 2016) that had examined the intercorrelations between satisfaction, investment size, quality of alternatives, and commitment. Across all studies, satisfaction had the largest aggregate association with commitment (r = 0.65), followed by investments (r = 0.53) and quality of alternatives (r = ?0.43). Several significant moderators of the relationships between the antecedents and commitment were also identified. Implications and future research directions are discussed.     

You are my best friend: Commitment and stability in adolescents’ same‐sex friendships

A 2‐wave longitudinal study among 678 early and 317 middle adolescents investigated the applicability of Rusbult’s investment model to adolescent best friendships and tested its usefulness in predicting friendship stability. Results showed that satisfaction, quality of alternatives, and investments predict commitment in friendships, both concurrently and over time. Furthermore, investment model variables predicted friendship stability and, among stable friendships, predicted the tendency to switch best friends. Commitment mediated the effects of satisfaction, investment, and alternatives on tendency to switch. As expected, gender and age differences were found in that alternatives were more important for older adolescents and associations among model variables were stronger for girls. Overall, the investment model proved useful in predicting commitment and stability in adolescents’ best friendships.
