Predictors of change in postmerger identification during a merger process: A longitudinal study.

Ilka H. Gleibs; Amélie Mummendey; Peter Noack

Adopting an intergroup perspective, the authors examined predictors of change in postmerger identification throughout a merger. Data were collected over 3 points of measurement from 157 students of a newly merged university. The 1st questionnaire was distributed 4 months after the implementation of the merger; the following 2 were distributed 6 months and 1 year thereafter. With its longitudinal design, this study replicates and extends past results by revealing predictors of change in organizational identification for members of the dominant and subordinate organizations throughout a merger process. As predicted, postmerger identification increased only slowly for members of both the dominant and the subordinate organizations. Multilevel models for change confirmed that the predictive effect of premerger identification on postmerger identification for members of the dominant organization dissipates over time. The effect of in-group typicality unexpectedly varied as a function of organizational membership and was stable over time. Perceived fairness in the merger process positively influenced postmerger identification across members of both organizations; over time the effect of fairness amplified.

Objective: Social isolation is a common problem in older people who move into care that has negative consequences for well-being. This is of particular concern for men, who are marginalised in long-term care settings as a result of their reduced numbers and greater difficulty in accessing effective social support, relative to women. However, researchers in the social identity tradition argue that developing social group memberships can counteract the effects of isolation. We test this account in this study by examining whether increased socialisation with others of the same gender enhances social identification, well-being (e.g. life satisfaction, mood), and cognitive ability. Method: Care home residents were invited to join gender-based groups (i.e. Ladies and Gentlemens Clubs). Nine groups were examined (five male groups, four female groups) comprising 26 participants (12 male, 14 female), who took part in fortnightly social activities. Social identification, personal identity strength, cognitive ability and well-being were measured at the commencement of the intervention and 12 weeks later. Results: A clear gender effect was found. For women, there was evidence of maintained well-being and identification over time. For men, there was a significant reduction in depression and anxiety, and an increased sense of social identification with others. Conclusion: While decreasing well-being tends to be the norm in long-term residential care, building new social group memberships in the form of gender clubs can counteract this decline, particularly among men.

Water clubs in residential care: Is it the water or the club that enhances health and well-being?

Ilka H. Gleibs; Catherine Haslam; S. Alexander Haslam; Janelle M. Jones

Recent research suggests that establishing water clubs in care homes can counteract the dangers of dehydration and enhance residents’ health and well-being. This study provided an experimental test of this idea, and also explored the possibility that it is the social interaction that clubs provide which delivers health-related benefits. Consistent with this hypothesis, the study found no evidence that, on its own, increased focus on water consumption enhanced residents’ health or well-being. However, residents who took part in water clubs showed improved levels of perceived social support, and those who participated in water and control clubs showed beneficial outcomes in terms of the number of General Practitioner calls they required. Consistent with a social identity approach to health and well-being, a mediation analysis also indicated that clubs achieve these positive outcomes by providing social support that helps to build a shared sense of social identity among residents.

OBJECTIVES The costs associated with traumatic injury are often exacerbated by the development of post-traumatic stress symptoms. However, it is unclear what decreases the development of post-traumatic symptoms over time. The aim of the present research was to examine the role of psychological symptoms and social group memberships in reducing the development of post-traumatic stress symptoms after orthopaedic injuries (OIs) and acquired brain injuries (ABIs). DESIGN AND METHODS A longitudinal prospective study assessed self-reported general health symptoms, social group memberships, and post-traumatic stress symptoms among participants with mild or moderate ABI (n= 62) or upper limb OI (n= 31) at 2 weeks (T1) and 3 months (T2) after injury. RESULTS Hierarchical regressions revealed that having fewer T1 general health symptoms predicted lower levels of T2 post-traumatic stress symptoms after OI but forming more new group memberships at T1 predicted lower levels of T2 post-traumatic stress symptoms after ABI. CONCLUSION A focus on acquiring group memberships may be particularly important in reducing the development of post-traumatic stress symptoms after injuries, such as ABI, which result in long-term life changes.

We can work it out: group decision-making builds social identity and enhances the cognitive performance of care residents

Group-based interventions have been argued to slow the cognitive decline of older people residing in care by building social identification and thereby increasing motivation and engagement. The present study explored the identity-cognition association further by investigating the impact of a group decision-making intervention on cognition. Thirty-six care home residents were assigned to one of three conditions: an Intervention in which they made decisions about lounge refurbishment as a group, a Comparison condition in which staff made these decisions, or a no-treatment Control. Cognitive function, social identification, home satisfaction, and lounge use were measured before and after the intervention. Participants in the Intervention condition showed significant increases on all measures, and greater improvement than participants in both Comparison and Control conditions. Consistent with social identity theorizing, these findings point to the role of group activity and social identification in promoting cognitive integrity and well-being among care residents.

Are all "research fields" equal? Rethinking practice for the use of data from crowdsourcing market places.

Ilka H. Gleibs

New technologies like large-scale social media sites (e.g., Facebook and Twitter) and crowdsourcing services (e.g., Amazon Mechanical Turk, Crowdflower, Clickworker) are impacting social science research and providing many new and interesting avenues for research. The use of these new technologies for research has not been without challenges, and a recently published psychological study on Facebook has led to a widespread discussion of the ethics of conducting large-scale experiments online. Surprisingly little has been said about the ethics of conducting research using commercial crowdsourcing marketplaces. In this article, I focus on the question of which ethical questions are raised by data collection with crowdsourcing tools. I briefly draw on the implications of Internet research more generally, and then focus on the specific challenges that research with crowdsourcing tools faces. I identify fair pay and the related issue of respect for autonomy, as well as problems with the power dynamic between researcher and participant, which has implications for withdrawal without prejudice, as the major ethical challenges of crowdsourced data. Furthermore, I wish to draw attention to how we can develop a “best practice” for researchers using crowdsourcing tools.

Unpacking the hedonic paradox: A dynamic analysis of the relationships between financial capital, social capital and life satisfaction

Ilka H. Gleibs; Thomas A. Morton; Anna Rabinovich; S. Alexander Haslam; John F. Helliwell

Does money buy happiness? Or is happiness derived from looking outwards towards our social networks? Many researchers have answered these questions by exploring whether the best predictor of well-being is either economic or social (or some fixed combination of the two). This paper argues for a dynamic perspective on the capacity for economic and social factors to predict well-being. In two studies, we show that both money (individual income) and community (social capital) can be the basis for individual happiness. However, the relative influence of each factor depends on the context within which happiness is considered, and how this shapes the way people define the self. Study 1 primes either money or community in the laboratory and demonstrates that such priming shifts individual values (so that they are economic vs. communal) and determines the extent to which income is more (vs. less) predictive of life satisfaction than social relations. Study 2 looks at these same priming processes in the external world (with people travelling to vs. from work). Both studies show that while money can become the basis of happiness when the self is defined in economic terms, the role of community relations in predicting happiness is more stable across contexts.

Group Dynamics in Automatic Imitation.

Ilka H. Gleibs; Neil E. Wilson; Geetha Reddy; Caroline Catmur

Imitation–matching the configural body movements of another individual–plays a crucial part in social interaction. We investigated whether automatic imitation is not only influenced by who we imitate (ingroup vs. outgroup member) but also by the nature of an expected interaction situation (competitive vs. cooperative). In line with assumptions from Social Identity Theory), we predicted that both social group membership and the expected situation impact on the level of automatic imitation. We adopted a 2 (group membership target: ingroup, outgroup) x 2 (situation: cooperative, competitive) design. The dependent variable was the degree to which participants imitated the target in a reaction time automatic imitation task. 99 female students from two British Universities participated. We found a significant two-way interaction on the imitation effect. When interacting in expectation of cooperation, imitation was stronger for an ingroup target compared to an outgroup target. However, this was not the case in the competitive condition where imitation did not differ between ingroup and outgroup target. This demonstrates that the goal structure of an expected interaction will determine the extent to which intergroup relations influence imitation, supporting a social identity approach.

“We get to decide”: the role of collective engagement in counteracting feelings of confinement and lack of autonomy in residential care

Ilka H. Gleibs; Stefanie Joy Sonnenberg; Catherine Haslam

Maintenance of well-being is recognized as important for well-being in residential care, but the particular contribution that social groups and group activities make in this context is rarely considered. To understand how we can foster well-being in care, this study explores (a) older adults’ general experiences of life in long-term residential care and (b) their particular experiences of participation in this group intervention. Ten semi-structured interviews were conducted with long-term care home residents and interview transcripts were analyzed thematically. Thematic analysis revealed two overriding themes that illustrated participants’ general experiences of life in care. The first theme, “care home as home,” suggests that adjustment and positive social relations with carers play a role in enhancing well-being. The second theme, “being stuck,” describes a general sense of confinement and a lack of control associated with living in long-term care. The significance of collective engagement became evident in relation to this second theme. Specifically, participants’ involvement in the group activity considered here was experienced as making a positive contribution to building social relations with other residents and, in doing so, as reducing residents’ sense of confinement and lack of control. Engagement in the group intervention and the resulting positive social relationships were thus experienced as a means of counteracting participants’ sense of being stuck. Overall, the findings point to the importance of group activities in fostering older adults’ autonomy and control—and thus well-being—in care.
