- Obesity increases risk of falling, but the effect of bariatric surgery on fall-related injuries is unknown. The aim of this study was therefore to study the association between bariatric surgery and long-term incidence of fall-related injuries in the prospective, controlled Swedish Obese Subjects study. At inclusion, body mass index was≥34kg/m2 in men and ≥38kg/m2 in women. The surgery per-protocol group (n=2007) underwent gastric bypass (n=266), banding (n=376), or vertical banded gastroplasty (n=1365), and controls (n=2040) received usual care. At the time of analysis (31 December 2013), median follow-up was 19 years (maximal 26 years). Fall-related injuries requiring hospital treatment were captured using data from the Swedish National Patient Register. During follow-up, there were 617 first-time fall-related injuries in the surgery group and 513 in the control group (adjusted hazard ratio 1.21, 95% CI, 1.07-1.36; P=0.002). The incidence differed between treatment groups (P<0.001, log-rank test) and was higher after gastric bypass than after usual care, banding and vertical banded gastroplasty (adjusted hazard ratio 0.50-0.52, P<0.001 for all three comparisons). In conclusion, gastric bypass surgery was associated with increased risk of serious fall-related injury requiring hospital treatment.

All work no play? Central Life Areas for Swedish Emerging Adults' Identity Exploration and Commitment
- 2016

Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- This study explores central life areas for Swedish emerging adults’ identity development. First, 149 emerging adults (102 women, 40 men, 7 other/unknown; Mage=24.9 SDage=3.1) completed the DIDS (Luyckx et al., 2008), which assesses different aspects of identity exploration and commitment without referring to specific life areas. Then participants answered an open-ended question concerning which life areas they had been thinking about when answering the questionnaire. Thematic analysis showed that almost all participants had thought about work/education, but 11 other life areas were also reported by the participants (e.g. family life and living arrangements). The reported life areas were largely similar across demographical variables, such as gender and occupational status. However, compare with participants who reported thinking about several life areas those who reported only thinking about work/education scored higher on ruminative exploration and exploration in depth, and lower on commitment making. This indicates that when individuals’ identity processes concern more than one life area their sense of identity may be more secure. Based on these findings, suggestions for future research are to focus more on what life areas are central for peoples’ identity development and on how development in different life areas co-evolve across time.

Emerging Adult Parents’ Coordination of Work and Family Commitments
- 2015
-
Ingår i: Paper presented at the 7th Conference on Emerging Adulthood. October 14-16, 2015, Miami, FL, USA.
-
Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- It has been proposed that the evaluation and coordination of commitments in different areas of life, such as work and family, becomes an important developmental task in late emerging adulthood (e.g., Pals, 1999). In the present study we explore how this coordination takes place by investigating how 33 (23 women) Swedish parents in late emerging adulthood reason around priorities between work and family. The participants took part in a semi-structured interview concerning their attitudes towards work/family priorities. Thematic analysis was used to analyze the material (Braun & Clarke, 2006). When describing their work/family priorities most parents talked about family as being more important than work, but many also talked about a strive for work/family balance. A small group said that work and family were equally important, but none of the participants said that they prioritized work over family. However, the results showed that wanting to prioritize family had different consequences for how different participants organized their work life. Most participants talked about how they were simply working their “regular hours”. Some, but not all, of these participants thought that working regular hours meant that their children had to spend too many hours in daycare, and some of them expressed a wish to work part time. A smaller group of participants (only women) work part time. These participants often talked about wanting to downshift and spend time with their children. In contrast, some participants talked about working long hours and putting in a lot of overtime. These participants often explained how this choice was a way for them to prioritize their family. For example, they talked about how working long hours would benefit their family financially or give them other advantages. Many participants said that their view of work/family priorities had changed when they became parents. Some of these participants said that before becoming parents they had thought that it would not be so difficult to combine work and family as it later turned out to be. Some also said that before becoming parents they had not thought much about work/family issues at all, or that their career had been more important to them before they became parents. A smaller group of participants also talked about how they expected, or had already experienced, that their view on work/family priorities would change during parenthood. For example, when their child got older and more independent they would be able to engage more in their work life. In conclusion, this study indicates that to prioritize family before work is normative among emerging adult Swedish parent, but that doing so can mean very different things to different people. Moreover, the results show that when emerging adults become parents work/family priorities is often a more pressing issue than it was before. This suggests that the transition to parenthood requires young people to negotiate their commitments in different life areas in relation to the new social realities of adult life.

Evolving identities: Contents and processes of identity development among people in their late twenties
- 2015
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- The overall aim of this thesis was to study contents and processes of identity development among people in their late twenties. The studies are based on identity status interviews and surveys performed with participants in the GoLD (Gothenburg Longitudinal study of Development), at ages 25 and 29. Study I investigated Swedish emerging adults’ expectations regarding possible future parenthood through content analysis of identity status interviews with the 124 (58 women) participants who were not yet parents at age 25. Thematic analysis of the participants’ interview narratives in the identity domains of parenthood and work/family priorities showed that most participants were sure they wanted to become parents, but often just not right now. First they wanted a stable financial situation, a romantic relationship, and time for self-focus. More women than men talked about parenthood as a social norm and wanted to prioritize both work and family equally. More men than women wanted to prioritize either work or family, most often family over work. The women gave more examples of how they intended to solve potential work/family conflicts. Study I thus indicated that many Swedish emerging adults postpone, but do not reject, parenthood. Moreover, the results indicate that in emerging adulthood more women than men consider these aspects of their identities. Study II concerned the process of identity development between ages 25 and 29 among the 124 (63 women) participants who took part in the study at both ages. The study had a special focus on how people continue to evolve their identities after making identity commitments. Each of the four identity statuses (identity achievement, moratorium, foreclosure, and identity diffusion) was equally common at both ages. Stability in identity status was typical of individuals assigned to all statuses except moratorium. Further analysis of interview narratives from participants assigned to identity achievement or foreclosure at both interview occasions (n = 55), showed that relevant processes of continued identity development after commitments have been made are: the ways in which people approach changing life conditions, the extent to which they continue to engage in meaning making, and how they continue to develop their personal life direction. Identity achievement was connected to a deepening of the identity narrative on all three dimensions, whereas developmental patterns connected to foreclosure were more diverse. Study II thus showed how identity development continues in the late twenties, also beyond identity achievement. Moreover, the study indicated that further evolvement might be a key process through which an established sense of identity can stay adaptive and flexible. Study III compared two models commonly used to study identity development, the identity status model and the dual-cycle model, among the 123 (62 women) participants who completed both measures at age 29. These models are based on the same theoretical framework and use the same terminology, though the associations found between them were only modest. Further, a validation of the Swedish version of the measure commonly used to study the dual-cycle model (Dimensions of Identity Development Scale; DIDS) could not confirm the processes in the model as a sufficient representation of the participants’ ratings on the DIDS. The findings in this study call for a reconsideration of what the identity status terminology actually means, what the identity status interview and the DIDS actually measure, and how these models reflect people’s identity development. In sum, this thesis shows some ways people may continue to evolve their identities as life unfolds. Further, the results suggests that to learn more about how people develop their identities we need to combine and evaluate different theoretical approaches and research methods, and keep an open mind regarding what people tell us about their experiences.

Tidskriftsartikel (refereegranskat)abstract
- The aim of this study was to investigate identity development in the late 20s in order to learn more about the continued identity development after identity commitments have been made. The starting point for the study was the contradiction between ideas of identity development as a lifelong process and identity status research showing that stability in identity development is common, particularly so once identitydefining commitments have been made. Identity status interviews were performed with 124 Swedish individuals (63 women) at ages 25 and 29. The 4 identity statuses were equally common at both ages, and stability in identity status between measurements was a typical pattern for individuals assigned to all identity statuses, except moratorium. Longitudinal analysis of interviews from participants assigned to identity achievement, or foreclosure at both occasions, resulted in a model of continued identity development after commitments have been made. The model showed that relevant processes in this identity development are: the ways in which individuals approach changing life conditions, to what extent they continue to engage in meaning making, and how they continue to develop their personal life direction. Identity achievement was connected to continued identity development, whereas developmental patterns connected to foreclosure were more diverse. In conclusion, the study showed that, regardless of identity status change or stability, identity development continues in the late 20s, also beyond identity achievement. Moreover, continued identity development is needed for an established sense of identity to stay adaptive and flexible.

Life on hold: Staying in identity diffusion in the late twenties

Tidskriftsartikel (refereegranskat)abstract
- This study adds to the understanding of the dark side of identity development by investigating what it means to experience long-term identity diffusion during the late twenties. In a study of change and stability in identity status between ages 25 and 29 (N ¼ 124; 63 women), seven participants were assigned to identity diffusion at both ages. Longitudinal analysis of interviews with these participants showed that long-term experiences of identity diffusion may be described through individuals' approach to changing life conditions, the extent to which they engage in meaning making, and how they develop their personal life direction. In questionnaires, participants reported few signs of psychological distress. Even so, qualitative analyses showed a general trend among participants to keep life on hold through decreased activity or increased haphazard activity in relation to changing life conditions, to make little new meaning, and in some cases to dissolve their personal life direction.

Deactivation of a Pd/Pt Bimetallic Oxidation Catalyst Used in a Biogas-Powered Euro VI Heavy-Duty Engine Installation
- 2019
-
Ingår i: Catalysts. - : MDPI. - 2073-4344. ; 9:12

Tidskriftsartikel (refereegranskat)abstract
- The reduction of anthropogenic greenhouse gas emissions is crucial to avoid further warming of the planet. We investigated how effluent gases from a biogas powered Euro VI heavy-duty engine impact the performance of a bimetallic (palladium and platinum) oxidation catalyst. Using synthetic gas mixtures, the oxidation of NO, CO, and CH4 before and after exposure to biogas exhaust for 900 h was studied. The catalyst lost most of its activity for methane oxidation, and the activity loss was most severe for the inlet part of the aged catalyst. Here, a clear sintering of Pt and Pd was observed, and higher concentrations of catalyst poisons such as sulfur and phosphorus were detected. The sintering and poisoning resulted in less available active sites and hence lower activity for methane oxidation.

Identity Development in Early Adulthood: A Continuous Journey

Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- To understand how people develop their identities in early adulthood and learn more about how identity in the twenties influences later development this study investigates identity development with a longitudinal design and integrates the identity status model with a narrative approach. Three research questions guided the investigations: (1) Which patterns of identity status change and stability may be observed throughout early adulthood? (2) Which processes of change may be identified within identity narratives from individuals coded to the same identity status, with established commitments, across early adulthood? (3) What is the relation between processes of change in identity narratives in the twenties and development in the early thirties, and does this differ between individuals coded to identity achievement and foreclosure across early adulthood? Identity status interviews (Marcia et al., 1993) were performed with 118 individuals (59 women) at ages 25, 29 and 33. Analyses revealed group-level changes in identity status across the three waves. However, typical patterns of individual identity status development between adjacent waves were patterns of stability in foreclosure (n= 20) or identity achievement (n= 25) (see Figure 1). In order to learn more about processes involved in maintaining identity commitments from age 25 into the early thirties identity narratives from individuals who followed these two stable patterns were investigated with longitudinal qualitative analysis. Case-summaries of similarities and differences between each participant’s interview narrative from, ages 25 and 29, as well as from age 29 and 33 were analyzed with thematic analysis (Braun & Clarke, 2006). These analyses resulted in a model, with three processes of identity development across the twenties and three processes of identity development across the early thirties (see Figure 2). All processes described changes on a continuum between two endpoints: the weakening endpoint reflected a shallower, more closed and firm identity narrative and the deepening endpoint reflected a richer identity narrative that had evolved between the interview occasions. Qualitative case-based analysis of participants’ development across the two models of identity development showed that evolved and flexible narratives (i.e., those involving processes of deepening) in the twenties were related to one or more processes of deepening, and no processes of shallower and firmer narratives (weakening) in the early thirties. The capacity to adjust the narrative to changing life conditions during the twenties was especially important for a continued development. However, individuals with shallower and firmer narratives in the twenties showed more varied results indicating more individual differences and could either continue in this weakening direction in their early thirties or evolve their identity narratives. With regards to identity status, most individuals coded to a stable achieved identity status continued to evolve their identity narrative from age 25 into the early thirties. The group of individuals coded to a stable foreclosed status showed diverse patterns of development with either continued processes of weakening or deepening, or a change in the opposite direction of their previous development. These results indicate development in identity narratives across early adulthood even without engaging in exploration before commitments are established.

Methodological Choices in Narrative Identity Research
- 2017

Ingår i: 24th Annual Conference International Society for Research on Identity (ISRI) Conference. Groningen, The Netherlands, May 18-21.
-
Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- The main focus in this presentation part of an interactive session on collecting narratives concerned collecting narratives with the identity status interview (Marcia, Waterman, Mattesson, Archer, & Orlofsky, 1993) and with this approach conduct longitudinal analysis of identity narratives (see e.g., Carlsson, Wängqvist, & Frisén, 2015; Wängqvist, Carlsson, van der Lee, & Frisén, 2016). By using the identity status interview this provides possibilities to investigate changes across time in the identity narratives (i.e., narrative change and stability), and explore mechanism behind processes of identity narrative development beyond exploration and commitment. This method also provides possibilities to investigate content of identity narratives and relation between identity processes and content in the narratives, all which can provide a deeper understanding of identity development.

Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- This study investigates patterns of identity development across early adulthood and the developmental processes behind this development by combining the identity status model with a narrative approach. Identity status interviews were performed with 118 Swedish individuals at ages 25, 29 and 33. The most common patterns of individual identity status development were patterns of stability in foreclosure (n= 20) or identity achievement (n= 25). Qualitative longitudinal analysis of these participants interview narratives resulted in a model with three processes of identity development in early adulthood: ‘Approach to change’, ‘Narrative coherence’ and ‘Participation in a broader life context’.

Identity Development and Romantic Relationships in the Late Twenties

Tidskriftsartikel (refereegranskat)abstract
- This two-wave study investigates identity processes and content in identity interviews concerning romantic relationships, and how this is related to involvement in romantic relationships in the late twenties. Results revealed that the four identity statuses were equally common at age 25 (N = 136) as they were at age 29 (N = 124). Although 54% were stable in identity status, 46% changed identity status between measurements. Stability in identity status was a typical pattern for all identity statuses, except moratorium. Overall, the content in individuals’ identity narratives seemed to express a strong norm concerning attitudes and expectations of romantic relationships. The few associations between identity status and identity content indicated a somewhat stronger adherence to norms in the foreclosure group and a somewhat lesser adherence to norms in the diffusion group. Involvement in a romantic relationship was more common among individuals who, at age 29, had established commitments and who viewed involvement in romantic relationships as an important life goal. The study illustrates how considering identity processes and content may lead to a deepened understanding of identity development within salient domains.

Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- This two-wave study investigates identity status and content of identity narratives concerning romantic relationships. Results revealed no difference in identity status distributions in the romantic relationships domain at age 25 (N = 136) compared to age 29 (N = 124). However, while 54% were stable in identity status, 46% changed identity status between measurements. Romantic relationships were expected to involve loyalty, openness, stability, togetherness, and intimacy. A majority wanted to get married and the reasons mainly involved practical advantages and symbolical meaning. This study illustrates how romantic relationships are important identity contexts and salient identity issues in the late twenties.
