Worry perception and its association with work conditions among healthcare workers during the first wave of the COVID-19 pandemic: a web-based multimethod survey at a university hospital in Sweden.

OBJECTIVES: In this study, we explored healthcare workers' (HCWs) worry perception and its association with their work situation during the first wave of the COVID-19 pandemic. DESIGN: A web-based multimethods survey including multiple choice and open-ended questions was used. SETTING: The study was conducted at a university hospital in Sweden. PARTICIPANTS: All HCWs who were working during the first wave of the COVID-19 pandemic in March-June 2020 were eligible. HCWs (n=6484, response rate=41%) from 69 departments fulfilled the study inclusion criteria and responded to the survey. Of them, we analysed data from the 3532 participants who replied to the open-ended questions (54% of the respondents). MAIN OUTCOMES MEASURES: Worry perception and its association with work conditions among HCWs. RESULTS: 29% (n=1822) and 35% (n=2235) of the responding HCWs experienced a daily or more than daily strong worry of being infected or infecting others with SARS-CoV-2. This finding could be further confirmed and explored with themes from the qualitative results: 'ambiguity of feeling safe and secure', 'being obliged to adapt to a new reality' and 'into the unknown'. The themes consisted of 6 main categories and 15 subcategories. The findings revealed that the two main drivers of worry perceived by HCWs were lack of personal protective equipment and fear of bringing the virus home to their families and friends. CONCLUSIONS: Worries of getting infected are common among HCWs during crises such as the COVID-19 pandemic. Several factors are raised that plausibly could minimise the negative effects of worry among HCWs. Thus, effective preventive work plans should be created, promoted and communicated in order to minimise the effects of such crises and support HCWs. By focusing on effective communication and preparedness, including access to relevant protective equipment and providing general support to HCWs, the work environment and patient care could be sustained during a crisis such as the COVID-19 pandemic.

Working conditions for healthcare workers at a Swedish university hospital infectious disease department during the COVID-19 pandemic: barriers and facilitators to maintaining employee wellbeing.

Background: Healthcare workers (HCWs) at infectious disease departments have held the frontline during the COVID-19 pandemic. This study aimed to identify barriers and facilitators to maintaining the employees' wellbeing that may be used to increase preparedness for future pandemics within ID Departments. Methods: In September 2020, a web-based survey on demographics and work environment was distributed to all HCWs at the Infectious Disease Department at Sahlgrenska University Hospital. Results were compared with a pre-COVID-19 survey from October 2019. A quantitative analysis of the overall effects of the pandemic on the working conditions of HCWs was conducted; in addition, a qualitative content analysis of open-ended responses was performed. Results: In total, 222 and 149 HCWs completed the pre-COVID-19 and COVID-19 surveys (84 and 54% response rate), respectively. Overall, we found significant changes regarding increased workload, lack of emotional support in stressful work situations, and inability to recover after shifts. These factors correlated both with younger age and concern of becoming infected. The open-ended answers (n = 103, 69%) revealed five generic categories (Workload; Organizational support; Worry and ethical stress; Capability; and Cooperation and unity) with a total of 14 identified factors representing plausible individual and organizational-level barriers or facilitators to sustained employee wellbeing. Conclusion: Younger HCWs as well as those expressing worries about contracting the infection were found to be particularly affected during the COVID-19 pandemic and these groups may require additional support in future outbreaks. Factors both increasing and decreasing the pandemic-induced negative health consequences for HCWs were identified; this knowledge may be utilized in the future.

Criminal recidivism of patients in Swedish forensic psychiatry: A register-based comparison study.

BACKGROUND: The aim of this study was to evaluate criminal outcomes of mentally disordered offenders in compulsory forensic psychiatric care during the year 2010 versus 2018. More specifically, we sought to identify the occurrence of new criminal sentences during ongoing treatment and possible factors associated with recidivistic criminality. Another aim was to map previous criminality, types of index crime, and whether there were any changes within this decade. METHODS: Crime-, clinical, and treatment-related variables were collected from the Swedish National Forensic Psychiatric Register for all unique inpatients registered from January 1-December 31 in 2010 (N = 717) and 2018 (N = 757). The mean, frequency, percentage, and standard deviation were calculated per variable and stratified by study year and gender. Between-group comparisons were made using t-tests and Chi-square tests. Binary logistic regression was performed to determine whether variables expected to be associated with recidivism showed any relation to criminal recidivism for each study cohort. RESULTS: Most patients were male and approximately one-quarter and one-half of the men, respectively, had a previous sentence for non-violent and violent crimes. The 2018 cohort showed significantly lower rates of sentences to forensic psychiatry with special court supervision although the numbers were low in both cohorts and for both men and women. Previous violent conviction was associated with criminal recidivism during treatment in 2010, while this was joined by index crime under the influence of alcohol/illicit drugs for the 2018 cohort. CONCLUSIONS: Overall, these results showed more similarities between the 2010 and 2018 cohorts then dissimilarities, while on the other hand some quite substantial differences were described between males versus females. The results of this study indicate that it may be possible to tailor forensic psychiatric treatment to gender as a proxy for other variables related to increased criminal recidivism in offenders sentenced to forensic psychiatric care.

Working conditions for hospital-based maternity and neonatal health care workers during extraordinary situations - A pre-/post COVID-19 pandemic analysis and lessons learned.

OBJECTIVE: The aim of this study was to investigate how the changed work routines during the COVID-19 pandemic has been affecting the working environment for hospital-based maternity and neonatal health care workers, and to identify preventive measures to be used in future situations when health care organizations are under pressure. METHODS: All maternity and neonatal health care workers in a Swedish university hospital were surveyed during October 2019 and September 2020. The data was analyzed by document analysis of implemented changes in working routines, a quantitative analysis of the overall effects on the working conditions, and a qualitative analysis of open-ended responses. RESULTS: A total of 660 maternity and neonatal health care workers completed the pre-COVID-19 survey (74% response rate) and 382 the COVID-19 survey (35% response rate). Lack of personal protective equipment, worry about becoming infected, uncertainty whether implemented changes were enough, and challenges in communicating updated routines had negative effects on maternity and neonatal health care workers' working conditions. Team spirit and feeling valued by peers had a positive effect. CONCLUSIONS: Results suggest that negative effects on maternity and neonatal health care workers' health can partly be prevented in future critical situations by creating a work climate that acknowledges the employees' worry about being infected, securing adequate pre-conditions for managers, creating a strong psychosocial safety climate and systematically improving the working conditions for the maternity and neonatal health care workers, as well as maintaining the positive perceived effects of increased team spirit and feeling valued by peers.

A Survey of Psychiatric Healthcare Workers' Perception of Working Environment and Possibility to Recover Before and After the First Wave of COVID-19 in Sweden.

Objective: This study aimed to investigate the impact of the first wave of the COVID-19 pandemic on perceived working environment, including the possibility to recover, among psychiatric healthcare workers (PHCWs) in comparison with pre-pandemic measures. Method: A link to an anonymous, web-based COVID-19 related survey was sent via email to all PHCWs at a university hospital in Sweden (n = 1,618) in September 2020. The response rate was 38% (566 of 1,507 eligible participants). Working environment survey responses collected in 2019 were used as pre-pandemic comparators. Statistical analyses were performed to assess overall impact over time on work demands, support, motivation, and recovery, stratified by professional role, and considering variables such as access to personal protective equipment. Results: The percentage of individuals responding negatively to statements about working environment increased significantly for most items after the first wave. Similarly, the increase of five of the investigated factors indicated a more negative perception of recovery during the pandemic. Registered nurses reported a greater negative impact of the pandemic on perceived working conditions and ability to recover than other professional groups. PHCWs working with patients with COVID-19 (35%) who reported being worried about becoming infected (12%) or infecting others (17%), or lacking adequate personal protective equipment (22%) were more negatively impacted regarding work environment-related items than those who did not. Conclusions: PHCWs' working environment and possibility for recovery were impacted by the first wave of the COVID-19 pandemic, nurses being most affected. Although psychiatric services do not directly care for patients with severe COVID-19 infection, the results from this study suggests that mental health services should also prepare for future pandemics.

A pre/post analysis of the impact of the COVID-19 pandemic on the psychosocial work environment and recovery among healthcare workers in a large university hospital in Sweden.

BACKGROUND: The impact of the COVID-19 pandemic on workload, mental health, and well-being of healthcare workers, and particularly those on the front-line, has received considerable attention. DESIGN AND METHODS: We surveyed hospital employees about their working environment during the pandemic and identified departments which were negatively affected in comparison to the pre-pandemic situation, as well as factors contributing to this. Setting and participants We surveyed all hospital employees at Sahlgrenska University Hospital, Sweden in September 2020 and compared results across departments and to the results of a large employee survey from October 2019. RESULTS: The overall impact of the pandemic on perceived working conditions and possibility for recovery differed among departments. During the pandemic, healthcare workers working with COVID-19 patients reported poorer working environments than other employees. Factors significantly related to perception of work environment and recovery during the pandemic included worries of being infected, departmental transfer, and having insufficient access to personal protective equipment. Men reported better working conditions than women in all, but one item and higher age was related to better perceived working environment. CONCLUSIONS: Our results indicate that the pandemic differentially affects hospital departments and underscores the multifactorial nature of this topic. Contributing factors to poor perceived working environment could be addressed at times of high workload, such as during the pandemic, including providing appropriate support to managers, ensuring possibility for recovery during working hours, and acknowledging worries about infection. Young healthcare workers and staff who are relocated due to the pandemic warrant special attention.

A register-based comparison study of Swedish patients in forensic psychiatric care 2010 and 2018.

PURPOSE: This study compared the characteristics of a population of Swedish patients in forensic psychiatric care in the year 2010 and 2018, with the goal of identifying similarities and differences in sociodemographic and clinical outcomes during the study period. FINDINGS: Significant changes in patient characteristics and treatment aspects were found, although similarities between the years were more common. Schizophrenia, schizotypal and delusional disorders were the most predominant primary diagnoses characterizing forensic psychiatric patients. From 2010 to 2018 there was also a development in care conditions supporting a shift from inpatient to outpatient care and from first-generation antipsychotic/neuroleptic to second-generation antipsychotics/atypical antipsychotics. More liberty restrictive such as physical restraints and forcible medication diminished while less restrictive coercive measures increased. There was also a decrease in the length of stay in forensic psychiatric care among those treated 2018 compared to those treated 2010, something that emerged as particularly discernible among male patients. CONCLUSION: In conclusion, the results from this study illustrate the similarities among a Swedish forensic psychiatric population between the years of 2010 and 2018, while also reflecting some changes in patient characteristics and clinical practice during the study period.

Literature Review: Evidence-Based Health Outcomes and Perceptions of the Built Environment in Pediatric Hospital Facilities.

PROBLEM: The current knowledge of evidence-based design for adults is not always implemented when hospital buildings are designed. Scientific data are sparse on the effects of hospital design in pediatric settings on health outcomes in children, parents, and staff. The objective of this review is to determine the evidence-based impact of the built environment in pediatric hospital facilities on health outcomes in children, parents, and staff. ELIGIBILITY CRITERIA: A systematic literature review was carried out on the electronic databases Cochrane Library, Embase, Medline and CINAHL from the period of 2008 to 2019. The review considered studies using either quantitative, qualitative, or mixed methodologies. SAMPLE: Out of 1414 reviewed articles the result is based on eight included articles. RESULTS: Two of these eight articles included health outcomes. The other six articles presented results on measures of perceptions and/or satisfaction for children, parents or staff with the built environment when transitioning to a new or renovated facility. These were generally higher for the new compared to the old facility. CONCLUSIONS: Given the small number of studies addressing the question posed in this review, no firm conclusions can be drawn. IMPLICATIONS: The review illustrates the need for more research in the pediatric setting assessing the evidence-based health outcomes of aspects of physical environmental design in pediatric hospitals or units in children, parents and staff.

The use of physical exercise in forensic psychiatric care in Sweden: a nationwide survey.

BACKGROUND: Exercise protects against somatic comorbidities and positively affects cognitive function and psychiatric symptoms in patients with severe mental illness. In forensic psychiatry, exercise is a novel concept. Staff at inpatient care facilities may be important resources for successful intervention. Little is known about staff's knowledge, attitudes and behaviors regarding exercise in forensic psychiatric care. AIMS: To translate, culturally adapt and test the feasibility of the Exercise in Mental Health Questionnaire-Health Professionals Version (EMIQ-HP) in the Swedish context, and to use this EMIQ-HP-Swedish version to describe staff's knowledge, attitudes and behaviors regarding exercise. METHOD: The EMIQ-HP was translated, culturally adapted, pilot-tested and thereafter used in a cross-sectional nationwide survey. RESULTS: Ten of 25 clinics and 239 health professionals (50.1%) participated. Two parts of the EMIQ-HP-Swedish version showed problems. Most participants considered exercise to be a low-risk treatment (92.4%) that is beneficial (99.2%). Training in exercise prescription was reported by 16.3%. Half of participants (52.7%) prescribed exercise and 50.0% of those undertook formal assessments prior to prescribing. CONCLUSIONS: Creation of the EMIQ-HP-Swedish version was successful, despite some clarity problems. Exercise appears to be prescribed informally by non-experts in Swedish forensic psychiatric care and does not address treatment goals.

Physical performance and physical activity of patients under compulsory forensic psychiatric inpatient care.

Research stresses the importance of physical activity in general psychiatric care. There is very little research made in the area of forensic psychiatric care. The aim of this exploratory, cross-sectional study was to assess various physical, psychological, and health variables of patients under compulsory forensic psychiatric inpatient care, and to examine correlations among these variables. Maximal oxygen uptake (VO2max), walking ability, running speed, and explosive leg strength were examined in 28 patients. Patients answered questionnaires about physical activity, aggression, stress, character maturity, and health-related quality of life (HRQL). The patients had a mean age of 33.6 years, a mean VO2max of 25.3 (8.4) mL 02/min/kg and a mean physical activity level of 268.0 (272.4) min/week. Results from the 6-min walk test were 612.5 (102.8) m. Nine patients had physical activity levels below the international recommendations of 150 min/week. Levels of aggression and stress were high and HRQL was low. The results indicate that patients in forensic psychiatric care are in a very poor physical state, which warrants physiotherapeutic interventions, adapted to the unique demands of forensic psychiatric care.

The Influence of Evidence-Based Design on Staff Perceptions of a Supportive Environment for Person-Centered Care in Forensic Psychiatry.

This prospective longitudinal study aimed to examine the relocation of three forensic psychiatric hospitals in Sweden into new facilities. The research focused on the effects of the physical and psychosocial environment and other staff-related parameters on the delivery of person-centered care after relocation. In forensic psychiatry, most relocations to new environments are to support a person-centered approach and to promote patients' rehabilitation and reintegration into society. Hopefully, this is undertaken in accordance with an evidence-based design strategy allowing improvement in staff satisfaction and working conditions as well as their capacity to provide individualized care. All staff members working on the wards of the facilities in question were invited to participate in the study. Data were collected prospectively between 2010 and 2014, before and after relocation of the forensic psychiatric clinics to new buildings. Structured validated questionnaires were employed. Staff members' job satisfaction and perceptions of a person-centered physical and psychosocial environment increased after relocation and provide evidence that staff perceptions of ward atmosphere in forensic psychiatric clinics are susceptible to factors in the physical and psychosocial environment. The importance of always taking the environmental factors into consideration, to achieve greater staff well-being and capacity to accomplish goals in forensic psychiatry, is emphasized.

The development of a brief screener for autism using item response theory.

BACKGROUND: Brief screening instruments focusing on autism spectrum disorder (ASD) that can be administered in primary care are scarce; there is a need for shorter and more precise instruments. The Autism-Tics, AD/HD and other Comorbidities inventory (A-TAC) has previously been validated for ASD reporting excellent validity. This study aims to determine the psychometric properties of each item in the ASD domain (17 items) in the A-TAC using item response theory (IRT), and thereby construct and validate a short form that could be used as a screening instrument in the general population. METHODS: Since 2004, parents of all 9-year-old Swedish twins have been invited to participate in a telephone interview in the Child and Adolescent Twin Study in Sweden (CATSS). The CATSS is linked to the National Patient Register (NPR), which includes data from in- and outpatient care. Data on ASD (A-TAC) collected in CATSS were compared with diagnoses from the NPR. Diagnoses that had been made both before (previous validity) and after (predictive validity) the interviews were included. The sample was divided into a developmental sample and a validation sample. An IRT model was fitted to the developmental sample and item parameters were used to select a subset of items for the short form. The performance of the proposed short form was examined in the validation sample by the use of receiver operation characteristic curves. RESULTS: Four items which were able to discriminate among individuals with more autism traits were deemed sufficient for use in the short form. The values of the area under the receiver operating characteristic curve for a clinical diagnosis of ASD was .95 (previous validity) and .72 (predictive validity). CONCLUSIONS: The proposed short form with 4 out of the original 17 items from A-TAC, showed excellent previous validity while the predictive validity was fair. The validity of the short form was in agreement with previous validations of the full ASD domain. The short form can be a valuable screening instrument in primary care settings in order to identify individuals in need for further assessment and for use in epidemiological studies.

Sustainability of a person-centered ward atmosphere and possibility to provide person-centered forensic psychiatric care after facility relocation.

OBJECTIVE: This longitudinal study aims to assess the sustainability of staff perceptions of ward atmosphere and their possibility to provide person-centered forensic psychiatric care after relocation to new hospitals that aimed to provide supportive work conditions for the staff to be able to perform care of high quality. METHODS: In this study we only present the result for the repeated measures, that is, only the individuals that performed both the questionnaires at baseline and at the three follow-ups. Data were collected prospectively between 2010 and 2016; before (baseline) and after relocation of the forensic psychiatric clinics to new buildings, i.e., after six months (follow-up 1), after one year (follow-up 2) and after two years (follow-up 3), respectively. Data were obtained by employing structured validated questionnaires. RESULTS: The main findings of this study display an improvement in the staff assessment of a person-centered atmosphere from baseline to follow-up 3 in the domains of safety, everydayness and community where safety was evaluated the highest. No sustainable significant changes were found concerning staff's assessment of the support for them to provide person-centered care. CONCLUSION: The findings show sustainability of person-centered ward atmosphere in forensic psychiatric care according to staff's assessment after relocation from traditional health care facilities to evidence-based designed premises. In this study the increased staff perception of the possibility to provide person-centered care in the new facilities could not be revealed as sustainability over the two years of follow-up.

The Autism-Tics, ADHD and other Comorbidities inventory (A-TAC): previous and predictive validity.

BACKGROUND: Reliable and easy to administer screening instruments focusing on neurodevelopmental disorders and associated conditions are scarce. The Autism-Tics, AD/HD and other Comorbidities inventory (A-TAC) has previously been validated and reporting good- excellent validity for several disorders. This article aims to expand these findings by including more conditions in a substantially larger sample augmented with the Swedish National Patient Register (NPR). METHODS: Since 2004 parents of all 9-year-old Swedish twins have been invited to participate in a telephone interview in the Child and Adolescent Twin Study in Sweden, CATSS. The CATSS is linked to the NPR which includes data from in- and outpatient care. Data on neurodevelopmental disorders (A-TAC) collected in CATSS were compared with diagnoses from the NPR. We investigated diagnoses that had been made both before (previous validity) and after (predictive validity) the interview. RESULTS: Sensitivity and specificity of A-TAC scores for predicting earlier or later clinical diagnoses were mostly good-excellent, with values of the area under the curve for a clinical diagnosis of autism spectrum disorder (ASD) of .98, attention deficit hyperactivity disorder (ADHD) .93, learning disorder (LD) .92, and oppositional defiant disorder (ODD) .99, with small differences in terms of previous and predictive analyses. A-TAC provided little validity for eating disorders. CONCLUSION: The result support previous claims: A-TAC is a broad screening instrument with a particular strength in assessing ASD, ADHD, LD, and ODD at ages 9 and 12, and also provides phenotypic information about other child psychiatric disorders.

The impact of facility relocation on patients' perceptions of ward atmosphere and quality of received forensic psychiatric care.

In recent years, large groups of forensic psychiatric patients have been relocated into new medium- and maximum-security forensic psychiatric facilities in Sweden, where a psychosocial care approach is embedded. From this perspective and on the assumption that physical structures affect the therapeutic environment, a prospective longitudinal study was designed to investigate the impact of the facility relocation of three forensic psychiatric hospitals on patients' perceptions of ward atmosphere and quality of received forensic psychiatric care. Participants were patients over 18 years of age sentenced to compulsory forensic psychiatric treatment. Data were obtained by validated questionnaires. Overall, 58 patients (78%) answered the questionnaires at baseline with a total of 25 patients (34%) completing follow-up 1 at six months and 11 patients (15%) completing follow-up 2, one year after relocation. Approximately two-thirds of the participants at all time-points were men and their age range varied from 18 to 69. The results of this study showed that poor physical environment features can have a severe impact on care quality and can reduce the possibilities for person-centered care. Furthermore, the study provides evidence that the patients' perceptions of person-centered care in forensic psychiatric clinics are highly susceptible to factors in the physical and psychosocial environment. Future work will explore the staff's perception of ward atmosphere and the possibilities to adapt a person-centered approach in forensic psychiatric care after facility relocation.

First report from the Swedish National Forensic Psychiatric Register (SNFPR).

To the best of our knowledge, the present register is the only nationwide forensic psychiatric patient register in the world. The aim of this article is to describe the content of the Swedish National Forensic Psychiatric Register (SNFPR) for Swedish forensic patients for the year 2010. The subjects are individuals who, in connection with prosecution due to criminal acts, have been sentenced to compulsory forensic psychiatric treatment in Sweden. The results show that in 2010, 1476 Swedish forensic patients were assessed in the SNFPR; 1251 (85%) were males and 225 (15%) were females. Almost 60% of the patients had a diagnosis of schizophrenia, with a significantly higher frequency among males than females. As many as 70% of the patients had a previous history of outpatient psychiatric treatment before becoming a forensic psychiatric patient, with a mean age at first contact with psychiatric care of about 20 years old for both sexes. More than 63% of the patients had a history of addiction, with a higher proportion of males than females. Furthermore, as many as 38% of all patients committed crimes while under the influence of alcohol and/or illicit drugs. This was more often the case for men than for women. Both male and female patients were primarily sentenced for crimes related to life and death (e.g., murder, assault). However, there were more females than males in treatment for general dangerous crimes (e.g., arson), whereas men were more often prosecuted for crimes related to sex. In 2010, as many as 70% of all forensic patients in Sweden had a prior sentence for a criminal act, and males were prosecuted significantly more often than females. The most commonly prescribed pharmaceuticals for both genders were antipsychotics, although more women than men were prescribed other pharmaceuticals, such as antidepressants, antiepileptics, and anxiolytics. The result from the present study might give clinicians an opportunity to reflect upon and challenge their traditional treatment methods.

Life History of Aggression scores are predicted by childhood hyperactivity, conduct disorder, adult substance abuse, and low cooperativeness in adult psychiatric patients.

The prevention of aggressive behaviours is a core priority for psychiatric clinical work, but the association between the diagnostic concepts used in psychiatry and aggression remains largely unknown. Outpatients referred for psychiatric evaluations of childhood-onset neuropsychiatric disorders (n=178) and perpetrators of violent crimes referred to pre-trial forensic psychiatric investigations (n=92) had comprehensive, instrument-based, psychiatric assessments, including the Life History of Aggression (LHA) scales. Total and subscale LHA scores were compared to the categorical and dimensional diagnoses of childhood and adult DSM-IV axis I and II mental disorders, general intelligence (IQ), Global Assessment of Functioning (GAF), and personality traits according to the Temperament and Character Inventory (TCI). Overall, the two groups had similar LHA scores, but the offender group scored higher on the Antisocial subscale. Higher total LHA scores were independently associated with the hyperactivity facet of attention-deficit/hyperactivity disorder (AD/HD), childhood conduct disorder, substance-related disorders, and low scores on the Cooperativeness character dimension according to the TCI. IQ and GAF-scores were negatively correlated with the LHA subscale Self-directed aggression. Autistic traits were inversely correlated with aggression among outpatients, while the opposite pattern was noted in the forensic group. The findings call for assessments of aggression-related behaviours in all psychiatric settings.

Specific HRQL instruments and symptom scores were more responsive than preference-based generic instruments in patients with GERD.

OBJECTIVE: To determine relative responsiveness of disease-specific and generic preference-based health-related quality of life instruments in gastroesophageal reflux disease (GERD). STUDY DESIGN AND SETTING: We compared standardized response means (SRM) of disease-specific and preference-based instruments in 217 outpatients with GERD. RESULTS: Quality of Life in Reflux and Dyspepsia and symptom scores were responsive across all domains, whereas global rating of change and Work Productivity and Activity Impairment-GERD only in single domains. The most responsive were Quality of Life in Reflux and Dyspepsia food/drink problems (SRM: 1.90, 95% confidence interval [CI]: 1.76-2.03) and vitality (SRM: 1.68, 95% CI 1.55-1.82) domains, Work Productivity and Activity Impairment-GERD workdays with reflux symptoms (SRM: 2.02, 95% CI 1.84-2.19), symptoms of heartburn (SRM: 1.83, 95% CI 1.69-1.96) and acid reflux (SRM: 1.48, 95% CI 1.35-1.62), and global rating of change in stomach problems (SRM: 2.19, 95% CI 2.05-2.32). The least responsive were Work Productivity and Activity Impairment-GERD domains related to hours absent at work (SRM: 0.22, 95% CI 0.05-0.38), reduced productivity at work (SRM: 0.66, 95% CI 0.48-0.83) and during other activities (SRM: 0.78, 95% CI 0.65-0.92), as well as emotional global rating of change (SRM: 0.72, 95% CI 0.58-0.85), and the standard gamble (SRM: 0.35, 95% CI 0.21-0.48), which was less responsive than the feeling thermometer (SRM: 0.92, 95% CI 0.78-1.05). CONCLUSIONS: In patients with GERD, disease-specific health-related quality of life instruments and symptom scores showed greater responsiveness than preference-based generic instruments. The feeling thermometer proved more responsive than the standard gamble.

The psychometric validation of the Sheehan Disability Scale (SDS) in patients with bipolar disorder.

Bipolar disorder (BD) adversely affects daily activities/functioning. The Sheehan Disability Scale (SDS) assesses disability in work/school activities, family relationships, and social functioning, and it evaluates the functional impact of psychiatric disorders. BD outpatients from 21 U.S. sites completed a battery of validated instruments (including the SDS) three times over 8-12 weeks. Instrument reliability (internal consistency, test-retest), validity (construct, convergent validity, known groups) and responsiveness were measured. There were missing data for the SDS in 2% of the 225 subjects with BD. One factor explained 82% of the variance. All SDS items had rotated factor loadings on the first factor >0.90, confirming the appropriateness of the SDS total score. Item-scale correlations surpassed 0.40. There was excellent internal consistency reliability for the SDS total score (Cronbach's alpha=0.89). Test-retest reliability was acceptable for the SDS total score (intraclass correlation coefficient=0.73). Correlations with other instruments demonstrate convergent and divergent validity. The SDS total and item scores significantly discriminated between (self-rated) overall health status, clinician-rated functional status, and clinician-rated depression, evidencing known group validity. The SDS demonstrated ability to detect change over time. The SDS is a valid, reliable measure of disability and is responsive to change over time when used in subjects with BD.

The Work Productivity and Activity Impairment Questionnaire for Patients with Gastroesophageal Reflux Disease (WPAI-GERD): responsiveness to change and English language validation.

BACKGROUND: A validated productivity questionnaire, the Work Productivity and Activity Impairment questionnaire for Gastroesophageal Reflux Disease (WPAI-GERD), exists for Swedish patients with GERD. OBJECTIVE: To assess responsiveness to change of the WPAI-GERD and construct validity of the English language version. METHODS: We used the WPAI-GERD in a before-after treatment clinical study of Canadian GERD patients with moderate or severe symptoms treated with esomeprazole 40 mg once daily for 4 weeks. We measured productivity variables including GERD-specific absence from work, reduced productivity while at work and reduced productivity while carrying out regular daily activities other than work during the preceding week. RESULTS: The analysis included 217 patients, of whom 71% (n = 153) were employed. Before treatment, employed patients reported an average 0.9 hours of absence from work due to GERD and 14.0% reduced work productivity (5.8 hours equivalent) in the previous week, as well as 21.0% reduced productivity in daily activities (all patients). After treatment, the corresponding figures decreased to 0.3 hours, 3.0% (1.1 hours equivalent) and 4.9%, respectively. Thus, the improvement (difference from start of treatment) in productivity was 0.6 hours (p = 0.011) for absence from work and 11.0% units (p < 0.001) for reduced work productivity (4.7 hours equivalent, p < 0.001). This translated into an avoided loss of work productivity of 5.3 hours in total on a weekly basis per employed patient. In addition, a 16.1% unit (p < 0.001) improvement for reduced productivity in activities was observed. Cross-sectional correlation coefficients of WPAI variables with symptoms (range 0.04-0.63) and health-related quality of life (HR-QOL; range 0.02-0.65) supported cross-sectional construct validity. Corresponding change score correlations between WPAI variables and HR-QOL (range 0.05-0.56) supported longitudinal construct validity of the WPAI-GERD while low change score correlations between productivity variables and relevant symptoms (range 0.06-0.34) did not. CONCLUSION: The English version of the WPAI-GERD showed good cross-sectional construct validity, and results indicated that the WPAI-GERD is responsive to change. Although the results also indicated that longitudinal construct validity may be poor, the overall findings suggest that further study of the instrument remains warranted.
