Forskningsöversikt (refereegranskat)abstract
- We report on the final electroweak measurements performed with data taken at the Z resonance by the experiments operating at the electron-positron colliders SLC and LEP. The data consist of 17 million Z decays accumulated by the ALEPH, DELPHI, L3 and OPAL experiments at LEP, and 600 thousand Z decays by the SLID experiment using a polarised beam at SLC. The measurements include cross-sections, forward-backward asymmetries and polarised asymmetries. The mass and width of the Z boson, m(Z) and Gamma(Z), and its couplings to fermions, for example the p parameter and the effective electroweak mixing angle for leptons, are precisely measured: m(Z) = 91.1875 +/- 0.0021 GeV, Gamma(Z) = 2.4952 +/- 0.0023 GeV, rho(l) = 1.0050 +/- 0.0010, sin(2)theta(eff)(lept) = 0.23153 +/- 0.00016. The number of light neutrino species is determined to be 2.9840 +/- 0.0082, in agreement with the three observed generations of fundamental fermions. The results are compared to the predictions of the Standard Model (SM). At the Z-pole, electroweak radiative corrections beyond the running of the QED and QCD coupling constants are observed with a significance of five standard deviations, and in agreement with the Standard Model. Of the many Z-pole measurements, the forward-backward asymmetry in b-quark production shows the largest difference with respect to its SM expectation, at the level of 2.8 standard deviations. Through radiative corrections evaluated in the framework of the Standard Model, the Z-pole data are also used to predict the mass of the top quark, m(t) = 173(+10)(+13) GeV, and the mass of the W boson, m(W) = 80.363 +/- 0.032 GeV. These indirect constraints are compared to the direct measurements, providing a stringent test of the SM. Using in addition the direct measurements of m(t) and m(W), the mass of the as yet unobserved SM Higgs boson is predicted with a relative uncertainty of about 50% and found to be less than 285 GeV at 95% confidence level.

Just Distribution : Rawlsian Liberalism and the Politics of Basic Income
- 2008
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Should liberal egalitarians endorse the idea of an unconditional basic income for all? This thesis defends a politics of unconditional universalism, offering a liberty-respecting and non-perfectionist basis for maximin-guided policies. The argument starts off from a Rawlsian justification of basic income in the context of institutional ideal theory. This view is based on the aim of maximising the prospects of the least advantaged in ways consistent with a robust protection of people’s effective freedom, the social bases of self-respect and access to meaningful activities at each stage of their lives.The thesis then moves on to specify such a position in response to objections based on ideas of fair cooperation and strong reciprocity. Linking John Rawls’ arguments on property-owning democracy to Philippe Van Parijs’ case for ‘gift-equalisation’, the study defends the view that a basic income is not inherently exploitative or beyond the scope of justice. To the extent that unconditional universalism is tied to the idea of sharing gift-like resources, it is just a matter of distributing wealth to which nobody has a justified prior claim, not an unfair redistribution of labour income.Introducing a problem of feasibility, however, the thesis also argues that unconditional wealth sharing may fail to meet liberal commitments and to counter structural exploitation unless constrained by other requirements of justice. The latter include a minimal autonomy constraint on maximin-objectives and the set of in kind transfers and social infrastructure needed to foster the activities and virtues on which the stability of this ideal relies. The thesis concludes with a study on the application of such standards to real-world conditions. It is argued that policy options combining a modest basic income with work-based social insurance and universal access to social services are more promising than strategies where a high basic income would replace core components of the welfare state.

Striving against adversity. : the dynamics of migration, health and poverty in rural South Africa
- 2009
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Background: The study is based in post-apartheid South Africa and looks at the health and well being of households in the rural northeast. Temporary migration remains important in South Africa because it functions as a mainstay for income and even survival of rural communities. The economic base of rural South Africans is surprisingly low because there is high inequity at a national level, within and between racial groups. There has now been a democratic system in place for 15 years and there is no longer restriction of mobility, but there remain high levels of poverty in rural areas and rising mortality rates. Migration patterns did not change after apartheid in the manner expected. We need to examine consequences of migration and learn how to offset negative impacts with targeted policies. Aims: To determine a relevant typology of migration in a typical rural sending community, namely the Agincourt sub-district of Mpumalanga, South Africa, and relate it to the urban transition at a national level – Paper (I) . To evaluate the dynamics of socio-economic status in this rural community and examine the relationship with migration – Paper (II). To explore, using longitudinal methods, the impact of migration on key dimensions of health, including adult and child mortality, and sexual partnerships, over a period of an emerging HIV/AIDS epidemic – Papers (III), (IV) and (V). Methods: The health and socio-demographic surveillance system (HDSS) is a large open cohort where the migration dynamics are monitored as they unfold. They are recorded as temporary or permanent migration. Settled refugees are captured using nationality on entry into the HDSS. Longitudinal methods, namely a household panel and two discrete time event history analyses, are used to examine consequences of migration. Results: Migration features prominently and different types have different age and sex profiles. Temporary migration impacts the most on socio-economic status (SES) and health, but permanent migration and the settlement of former refugees are also important. Remittances from migrants make a significant difference to SES. For the poorest households the key factors improving SES are government grants and female temporary migration, while for less poor it is male temporary migration and local employment. Migration has been associated with HIV. Migrants that return more frequently may be less exposed to outside partners and therefore less implicated in the HIV epidemic. There are links between migration and mortality including a higher risk of dying for returnee migrants compared to permanent residents. A mother’s migration can impact on child survival after accounting for other factors. There remains a higher mortality risk for children of Mozambican former refugee parents. Interpretation: Migration changes the risks and resources for health with positive and negative implications. Measures such as improved transportation and roads should be seen as a positive, not a negative intervention, even though it will create more migration. Health services need to adapt to a reality of high levels of circular migration ranging from budget allocation to referral systems. Data should be enhanced at a national level by accounting for temporary migration in national censuses and surveys. At individual level we can offset negative consequences by treating migrants as persons striving against adversity, instead of unwelcome visitors in our better-off communities.

Imagining Safe Space : The Politics of Queer, Feminist and Lesbian Pornography
- 2012
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- There is a current wave of interest in pornography as a vehicle for queer, feminist and lesbian activism. Examples include Dirty Diaries: Twelve Shorts of Feminist Porn (Engberg, Sweden, 2009), the Pornfilmfestival Berlin (2006-) and the members-only Club LASH in Stockholm (1995-).Based on ethnographic fieldwork designed around these cases, the purpose of the thesis is to account for, historicize and understand this transnational film culture and its politics and ethics. The fieldwork consists of interviews, questionnaires and participant observation, including participation as one of the filmmakers in Dirty Diaries.The thesis studies queer, feminist and lesbian pornography as an interpretive community. Meanings produced in this interpretive community are discussed as involving embodied spectatorial processes, different practices of participation in the film culture and their location in specific situations and contexts of production, distribution and reception.The thesis highlights a collective political fantasy about a safe space for sexual empowerment as the defining feature of this interpretive community. The figure of safe space is central in the fieldwork material, as well as throughout the film culture’s political and aesthetic legacies, which include second wave feminist insistence on sexual consciousness-raising, as well as the heated debates referred to as the Sex Wars. The political and aesthetic heterogeneity of the film culture is discussed in terms of a tension between affirmation and critique (de Lauretis, 1985). It is argued that the film culture functions both as an intimate public (Berlant, 2008) and as a counter public (Warner, 2002).Analyzing research subjects’ accounts in terms of embodied spectatorship (Sobchack, 2004, Williams, 2008), the thesis examines how queer, feminist and lesbian pornography shapes the embodied subjectivities of participants in this interpretive community and potentially forms part of processes of sexual empowerment.

Hand-in-Hand in the Peach Flower Land : Analysis of Huí Cadre Agency in the Literature Propaganda Magazine Kāidū River in the North-West Borderland of China
- 2023
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- This thesis studies how mínzú (ethnic) agency is effectuated through propaganda literature among Muslim minority cadres in the Yānqí Huí Autonomous County of the Xīnjiāng Uyghur Autonomous Region of North-West China in the 2010s. The aim is to understand to what extent and in what ways mínzú identification can have a socio-politically significant impact on the activities of mínzú cadres in a restrictive environment and in a medium where mínzú agency is controversial and difficult to implement. The thesis is motivated on the one hand by studies that presume the “monolithic” nature of cadres that speak the language of the Party-State, and on the other hand by studies that too readily presume that the invocation of Party-State orthodoxy is mere lip-service paid to authorities.The questions are approached by studying the implications that the cadre writers’ literary activities have on Huí mínzú identity in the context of the discourses that they invoke. In the process, national concerns are contrasted to mínzú concerns in order to evaluate and ascertain the intentional nature behind the invocation of mínzú concerns.The implications of the writers’ literary activities are identified by studying the role that they play in the discursive context of the literary Kāidū River magazine. The study finds that the discursive context can best be described as hybrid in nature, involving the three “sub” discourses of Neo-Confucian cosmology, Republican race theory, and Maoist thought transformation. The first revolves around a notion of cosmic truth, the second around the significance of mínzú or nations, and the third around the threats of and safeguards against ideological pollution. By employing this hybrid discourse of truth, the writers legitimized their texts as state orthodoxy.Having identified the implications relevant for the formulation of Huí identity, the thesis describes the ways in which the Muslim minority cadres attempted to address mínzú concerns. Although national concerns permeated the texts of the Kāidū River, the writers demonstrated awareness of and the ability to work around the restrictions of Party-State discourse during the early 2010s—at least to some extent. Through selective interpretation, they legitimized off-center views while remaining within the discourse of "truth.”The thesis demonstrates how the intention of mínzú authors can be identified by studying the implications of their texts in the discursive context within which they are embedded, even when these implications are multivalent. Significantly, the thesis is able to do so by studying how relevant implications consistently are invoked and examining the degree of tolerance for contradictory meaning.

Antibiotic use among children in low- and middle-income countries : Studies on global trends, and contextual determinants of antibiotic prescribing in Eastern Uganda
- 2022
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- This thesis aimed to systematically map trends in reported antibiotic use (RAU) among sick under-five children across low- and middle-income countries (LMICs) in 2005-2017, and, to understand the contextual determinants of antibiotic prescribing in Eastern Uganda. Based on 132 national surveys from 73 LMICs, and using Bayesian linear regression models, trends in RAU among sick under-five children (with symptoms of fever, diarrhoea or cough with fast/difficult breathing) across LMICs in 2005-2017 were mapped by WHO region, World Bank country income group, symptom complaint (Study-I), and by the following user characteristics: rural/urban residence, maternal education, household wealth and source of care (Study-II). To provide context, Study-III investigated patterns and contextual determinants of antibiotic prescribing for febrile under-five outpatients (FUO) attending 37 primary and secondary healthcare facilities across Bugisu, a sub-region in Eastern Uganda, based on a healthcare facility survey, and a two-year retrospective review of outpatient registers from January 2019-December 2020. To further strengthen the understanding of contextual determinants of antibiotic prescribing, in Study-IV, 10 focus group discussions and 10 in-depth interviews were conducted with 85 healthcare providers across primary and secondary healthcare facilities in Bugisu, and analysed using thematic analysis.A modest (17%) relative increase in RAU for sick under-five children across LMICs in 2005-2017 was found, with about 43% of the children reportedly receiving antibiotics for their illness in 2017. Low-income, African, and South-East Asian countries consistently recorded the lowest RAU for sick under-five children. Within LMICs, RAU for sick under-five children increased across all user groups in 2005-2017 but remained lowest among the poorest children, those living in rural areas, and having mothers with the lowest education levels. In Bugisu, 62.2% of FUO in surveyed healthcare facilities received antibiotic prescriptions. Amoxicillin and co-trimoxazole accounted for two-thirds of all antibiotic prescriptions. Cotrimoxazole and ampicillin/cloxacillin were prescribed, despite not being indicated in any of the reported conditions in Study-III. Among other interrelated factors across multiple levels of the health system, availability of antibiotics and diagnostics within healthcare facilities, caregiver demands, and governance at national and sub-national levels were important health worker considerations in antibiotic prescribing for febrile under-five patients.These studies suggest that inequitable access to antibiotics remains a challenge between and within LMICs. Yet, misuse and wastage of antibiotics persists in the same populations with the greatest lack of access to antibiotics and formal healthcare services. A health systems strengthening approach is required to improve antibiotic stewardship and overall quality of care in LMICs.

- Polygenic risk scores (PRS) for epithelial ovarian cancer (EOC) have the potential to improve risk stratification. Joint estimation of Single Nucleotide Polymorphism (SNP) effects in models could improve predictive performance over standard approaches of PRS construction. Here, we implemented computationally efficient, penalized, logistic regression models (lasso, elastic net, stepwise) to individual level genotype data and a Bayesian framework with continuous shrinkage, “select and shrink for summary statistics” (S4), to summary level data for epithelial non-mucinous ovarian cancer risk prediction. We developed the models in a dataset consisting of 23,564 non-mucinous EOC cases and 40,138 controls participating in the Ovarian Cancer Association Consortium (OCAC) and validated the best models in three populations of different ancestries: prospective data from 198,101 women of European ancestries; 7,669 women of East Asian ancestries; 1,072 women of African ancestries, and in 18,915 BRCA1 and 12,337 BRCA2 pathogenic variant carriers of European ancestries. In the external validation data, the model with the strongest association for non-mucinous EOC risk derived from the OCAC model development data was the S4 model (27,240 SNPs) with odds ratios (OR) of 1.38 (95% CI: 1.28–1.48, AUC: 0.588) per unit standard deviation, in women of European ancestries; 1.14 (95% CI: 1.08–1.19, AUC: 0.538) in women of East Asian ancestries; 1.38 (95% CI: 1.21–1.58, AUC: 0.593) in women of African ancestries; hazard ratios of 1.36 (95% CI: 1.29–1.43, AUC: 0.592) in BRCA1 pathogenic variant carriers and 1.49 (95% CI: 1.35–1.64, AUC: 0.624) in BRCA2 pathogenic variant carriers. Incorporation of the S4 PRS in risk prediction models for ovarian cancer may have clinical utility in ovarian cancer prevention programs.

Exploring effective descriptions of gauge fields and strings : A Lagrangian approach with insights from color-kinematics duality
- 2024
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- The concept of a color-kinematics duality is an important driving force in advancing the modern understanding of scattering amplitudes, in both field theory and string theory. Yet, open questions remain that motivate the need for a deeper understanding of the duality. A central open question is: do the kinematic numerators admit a Lie-algebraic origin, just like the corresponding color factors? The answer may be intimately related to a detailed understanding of the duality at the level of the Lagrangian. For pure Yang-Mills theory, a cubic Lagrangian which directly computes color-dual numerators is not yet known. In this thesis, we make progress in this direction by constructing a cubic Lagrangian in terms of the ordinary gauge field and a set of auxiliary fields. The contributions to the numerators are split into independent sectors specified by the number of contractions between polarization vectors. We find a novel Lagrangian with a finite number of fields and interactions that computes color-dual Yang-Mills numerators to any multiplicity, valid for sectors with up to two polarization contractions. In the context of string theory, insights from the color-kinematics duality have revealed interesting relations between string and field theory amplitudes. The sector of open bosonic string amplitudes where transcendental numbers are absent is known to be described by a higher-derivative field theory. The spectrum of this theory includes a massless gauge field and extra massive modes: by integrating the latter out from the Lagrangian, we obtain an expansion in the inverse string tension, which is a low-energy effective description of the dynamics of the massless modes of the bosonic string. This thesis develops the general method and explicitly writes down the operators entering the effective Lagrangian through fourth order in the inverse string tension.

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: Time management skills are essential for living in modern society. People with mental or neurodevelopmental disorders typically have cognitive limitations, including affected time management, which might lead to poor occupational balance, low self-efficacy, and poor parental sense of competence. "Let's Get Organized" (LGO) is a recently developed manual-based group intervention to train time management skills. The aim of this trial is to evaluate the efficiency of the Swedish version of LGO (LGO-S) compared to treatment as usual (individual occupational therapy) to improve time management for adults with impaired time management skills due to mental or neurodevelopmental disorders. Furthermore, to evaluate if the intervention is a cost-effective way to improve the quality of life and time management skills of these individuals, we will conduct a health economic evaluation.METHODS: The trial will have a multi-centre, open, parallel randomised controlled design. A total of 104 adults with cognitive limitations due to mental or neurodevelopmental disorders will be recruited from open psychiatric or habilitation care units. Outcomes will be measured before and after a 10-week intervention, with a follow-up 3 months after completing the intervention. The primary outcome will be self-assessed time management skills. Secondary outcomes will be e.g. self-assessed skills in organisation and planning, regulation of emotions, satisfaction with daily occupations, occupational balance, self-efficacy, and quality-adjusted life years.DISCUSSION: A recent feasibility study has shown promising results for LGO-S, and a randomised trial will provide robust evidence for the possible efficacy of LGO-S in comparison to treatment as usual.TRIAL REGISTRATION: ClinicalTrials.gov NCT03654248 .

Let’s Get Organized : pilot study of an occupational therapy group intervention aimed to improve time management skills
- 2018
-
Konferensbidrag (refereegranskat)abstract
- Introduction: Managing daily life activities requires time management and organizing skills. Individuals with cognitive disabilities commonly have poor ability to manage time, which often results in decreased ability to properly manage daily life activities. An intervention aimed to increase time management skills is "Let’s get organized" (LGO).Objective: The current pilot study was designed to explore the outcome of the LGO with regards to time management skills, executive functions and satisfaction with daily occupations among individuals with cognitive disabilities.Method: Persons with mental and neurodevelopmental disorder with decreased ability to manage time in daily life according to self-rated measures, were recruited by their local Occupational Therapist. All participants took part in LGO, which is a 10-week manual based group intervention with weekly meetings. Each session has a separate theme, with a common structure and goal to improve time management skills and to implement the use of a calendar in daily life. Measured outcomes were time management skills (Assessment of Time Management Skills), executive functioning (Weekly Calendar Planning Activity) and overall satisfaction with daily activities (Satisfaction with Daily Occupations).Results: In all 55 persons participated in the study. Preliminary results from a subgroup indicate significant improvements in time management skills, in aspects of executive functioning and in overall satisfaction with daily occupations.Conclusion: The LGO seems to be a promising intervention to improve time management skills and satisfaction with daily occupations in the short term. The used instruments appear to be sensitive to capture change from LGO.

- IMPORTANCE: There is a need for evidence-based occupational therapy interventions to enhance time management in people with time management difficulties.OBJECTIVE: To pilot test the first part of the Let's Get Organized (LGO) occupational therapy intervention in a Swedish context by exploring enhancements of time management skills, aspects of executive functioning, and satisfaction with daily occupations in people with time management difficulties because of neurodevelopmental or mental disorders.DESIGN: One-group pretest-posttest design with 3-mo follow-up.SETTING: Outpatient psychiatric and habilitation settings.PARTICIPANTS: Fifty-five people with confirmed or suspected mental or neurodevelopmental disorder and self-reported difficulties with time management in daily life.INTERVENTION: Swedish version of Let's Get Organized (LGO-S) Part 1, with structured training in the use of cognitive assistive techniques and strategies using trial-and-error learning strategies in 10 weekly group sessions of 1.5 hr.OUTCOMES AND MEASURES: Time management, organization and planning, and emotional regulation were measured with the Swedish version of the Assessment of Time Management Skills (ATMS-S). Executive functioning was measured with the Swedish version of the Weekly Calendar Planning Activity, and satisfaction with daily occupations was assessed with the Satisfaction With Daily Occupations measure.RESULTS: Participants displayed significantly improved time management, organization and planning skills, and emotional regulation, as well as satisfaction with daily occupations. Aspects of executive functioning were partly improved. ATMS-S results were sustained at 3-mo follow-up.CONCLUSION AND RELEVANCE: LGO-S Part 1 is a promising intervention for improving time management skills and satisfaction with daily occupations and should be investigated further.WHAT THIS ARTICLE ADDS: This study shows that LGO-S Part 1 is feasible for use in psychiatric and habilitation outpatient services. The results are promising for improved time management skills, organization and planning skills, and satisfaction with daily occupations and need to be confirmed in further studies.

- Studies have demonstrated high rates of mortality in people with proximal femoral fracture and SARS-CoV-2, but there is limited published data on the factors that influence mortality for clinicians to make informed treatment decisions. This study aims to report the 30-day mortality associated with perioperative infection of patients undergoing surgery for proximal femoral fractures and to examine the factors that influence mortality in a multivariate analysis.SettingProspective, international, multicentre, observational cohort study.ParticipantsPatients undergoing any operation for a proximal femoral fracture from 1 February to 30 April 2020 and with perioperative SARS-CoV-2 infection (either 7 days prior or 30-day postoperative).Primary outcome30-day mortality. Multivariate modelling was performed to identify factors associated with 30-day mortality.ResultsThis study reports included 1063 patients from 174 hospitals in 19 countries. Overall 30-day mortality was 29.4% (313/1063). In an adjusted model, 30-day mortality was associated with male gender (OR 2.29, 95% CI 1.68 to 3.13, p<0.001), age >80 years (OR 1.60, 95% CI 1.1 to 2.31, p=0.013), preoperative diagnosis of dementia (OR 1.57, 95% CI 1.15 to 2.16, p=0.005), kidney disease (OR 1.73, 95% CI 1.18 to 2.55, p=0.005) and congestive heart failure (OR 1.62, 95% CI 1.06 to 2.48, p=0.025). Mortality at 30 days was lower in patients with a preoperative diagnosis of SARS-CoV-2 (OR 0.6, 95% CI 0.6 (0.42 to 0.85), p=0.004). There was no difference in mortality in patients with an increase to delay in surgery (p=0.220) or type of anaesthetic given (p=0.787).ConclusionsPatients undergoing surgery for a proximal femoral fracture with a perioperative infection of SARS-CoV-2 have a high rate of mortality. This study would support the need for providing these patients with individualised medical and anaesthetic care, including medical optimisation before theatre. Careful preoperative counselling is needed for those with a proximal femoral fracture and SARS-CoV-2, especially those in the highest risk groups.Trial registration numberNCT04323644

- Time management is a key OT intervention component. Valid and reliable instruments are essential for evaluating rehabilitation and OT interventions. The results of this study show that the Assessment of Time Management Skills has good measurement properties and consistent and replicable items and is useful in English-speaking countries. It can provide valid measures of time management skills, organization and planning skills, and regulation of emotion in a general population and presumably also a population with cognitive impairment.

- Purpose: The aim of the study was to investigate to what extent time management skills are associated with general self-efficacy and parental sense of competence, and if there are any differences between individuals with and without cognitive disabilities in these aspects.Material and Methods: The study had a comparative cross-sectional design. Totally 86 individuals with cognitive disabilities (of whom 31 were parents), and 154 without disabilities (of whom 68 were parents) were included (N = 240). The Swedish versions of the Assessment of Time Management Skills (including time management, organisation & planning, and regulation of emotion subscales), General Self-Efficacy, and Parental Sense of Competence scale (including satisfaction, efficacy, and interest subscales) were used to collect data.Results: There were significant differences (p < .001) between individuals with and without cognitive disabilities in all three subscales of Assessment of Time Management Skills and in General Self-Efficacy. Overall, individuals with a cognitive disability scored lower than persons without cognitive disabilities. A significant difference was observed between parents in all three subscales of time management skills after controlling for age and education (p < .0005). Parents with cognitive disabilities, compared to parents without cognitive disability, scored significantly lower in all measured scales, except for the interest subscale. In parents with a cognitive disability, there was a significant correlation between all three subscales of Time Management Skills and satisfaction. Among parents without a cognitive disability there was a significant correlation between time management; and organisation & planning subscales; and efficacy, and between General Self-Efficacy and time management.Conclusions: Poor time management, planning and organisational skills, as well as a deficit in regulation of emotions may have a negative impact on general self-efficacy and parental sense of competence.

- Background: To perform daily activities, time management and organizational skills are essential and therefore also important intervention focus in occupational therapy. To guide and evaluate intervention, valid and reliable instruments that measure time management and organization skills are necessary. The aim of this study was to evaluate the psychometric properties of the Assessment of Time Management Skills (ATMS).Methods: Eligible participants were volunteer adults from the general population who were aged between 18 and 65 years, had a good understanding of English, and were not currently involved in any training or education to improve time management. The ATMS was filled out as a computer-administered survey. Rasch measurement analysis was used to evaluate the validity and aspects of reliability of the ATMS.Results: In total, 241 adults (112 male and 129 female, mean age = 40) participated. The analysis of principal components of residuals (PCA) and the item goodness-of-fit indicated that the 30-item scale does not measure only one single trait. Three subscales, time management (11 items), organization and planning (11 items), and regulation of emotion (5 items), were detected. One item each on the 11-item subscale showed misfit, but they were kept due to high relevance. All three subscales showed excellent results on analyses of PCA, local independence, and reliability.Conclusions and Relevance: ATMS can provide valid measures of time management, organization and planning skills, and regulation of emotion in a general population and presumably also in a population with cognitive impairment. The measure is useful for occupational therapists in assessing patients' strengths and barriers in time management skills. It can also be useful in identifying the necessity of training time management skills, to guide OT intervention programs and to evaluate interventions.What This Article Adds: Knowledge about the psychometric properties and usefulness of the ATMS in English-speaking countries.
