- Abstract
Drawing on self-determination theory, this study examines how using personal strengths at work in the morning is associated with different types of performance throughout the workday. Momentary satisfaction of the needs for autonomy, relatedness and competence are proposed as mechanisms that differentially link strengths use to four different performance outcomes: task accomplishment, goal attainment, organizational citizenship behaviour and counterproductive work behaviour. We collected data from 216 Dutch employees in a large variety of sectors twice a day for one workweek (N = 1470 observations) using a smartphone application. Results of multilevel structural equation modelling showed that momentary satisfaction of the needs for autonomy and competence at noon mediated the positive relationship between morning strengths use and afternoon task accomplishment and goal attainment. Furthermore, satisfaction of the need for relatedness mediated the positive relationship between morning strengths use and afternoon organizational citizenship behaviour, but not the negative relationship between morning strengths use and counterproductive work behaviour. These findings deepen our understanding of strengths use theory and uncover novel insight on the temporal aspects of strengths use within a working day.

Primary progressive aphasia (PPA) is a form of dementia in which brain circuits responsible for language and speech show progressive impairments. Based on consensus criteria PPA is divided into 3 main variants: a nonfluent/agrammatic, a semantic and a logopenic variant. Each variant has specific clinical characteristics, including neuropsychiatric symptoms, and is associated with different neuropathological findings. We describe a 51-year-old man with neuropsychiatric symptoms and progressive language disturbances. The diagnosis PPA was established after an extensive work-up in a psychiatric clinic. We describe which factors contributed to this complex diagnostic process and discuss why knowledge of this disorder is relevant for psychiatrists.

- Abstract
In teams, some people are truly noticed when present, and sorely missed when absent. Often they are described as the “life of the party”, but in a formal team context, we refer to their behaviors as “team boosting behavior”. These behaviors have the potential to affect the team’s processes. In three consecutive studies, we conceptualized these behaviors and developed and validated a questionnaire to measure them. In Study 1, we defined team boosting behaviors as the extent to which team members exhibit mood-enhancing, energizing, and uniting behaviors, directed towards team members. In Study 2, we developed and validated an instrument to measure team boosting behaviors using a sample of team members in work and sports teams (N = 385). Results supported a three-factor structure and indicated positive relationships with conceptually similar constructs. In Study 3, we cross-validated the three-factor structure among the members of 120 work teams and offer evidence for convergent and criterion validity of the Team Boosting behavior scale. The behaviors related positively to a positive team climate, team work engagement, and leader-rated team performance. The scale provides a useful tool for future empirical research to study the role of individual team boosting behaviors in shaping team processes and outcomes.

A field study was performed in a hospital pharmacy to identify positive and negative influences on the process of detection of and further recovery from initial errors or other failures, thus avoiding negative consequences. The analysis revealed that organizational culture with regard to following procedures needed reinforcement, some procedures could be improved, building in extra checks was worthwhile and that supporting unplanned recovery was essential for problems not covered by procedures.

- Abstract
In de doeloriëntatieliteratuur bestaat discussie over de inconsistente relaties tussen leer- en prestatiedoeloriëntatie en (werk)prestaties. In de huidige studie wordt beargumenteerd dat deze inconsistente bevindingen wat betreft werkprestatie deels kunnen worden verklaard door de verschillende manieren waarop prestaties worden gemeten. In een steekproef van 117 werknemers werden door middel van clusteranalyse vier profielen van objectieve en subjectieve indicatoren van werkprestatie samen met doeloriëntatie geïdentificeerd. De resultaten lieten zien dat leer- en prestatiedoeloriëntatie samengingen met specifieke combinaties van werkprestatie-indicatoren. Werknemers met een sterke leerdoeloriëntatie hadden goede financiële prestaties maar gaven zichzelf een relatief lage beoordeling, terwijl werknemers met een sterke prestatiedoeloriëntatie minder goede financiële prestaties leverden, maar zichzelf wel goed beoordeelden en ook positief beoordeeld werden door hun leidinggevenden. De verschillende werknemersprofielen geven daarmee een beter inzicht in de samenhang tussen doeloriëntatie en werkprestatie. ___ Within achievement goal orientation theory there is an ongoing debate regarding the ambiguous relationship of mastery and performance goal orientation with (work) performance outcomes. This study focused on job performance, arguing that the ambiguous relationships between achievement goal orientation and job performance can be explained by measuring job performance. Based on a sample of 117 employees, cluster analyzes identified four profiles of objective and subjective job performance indicators in collaboration with employees' achievement goal orientation. The findings showed that mastery and performance goal orientation are related to specific performance profiles, indicating very good financial performance and an average self-rating of performance for employees with high scores on mastery goal orientation. In contrast, financial performance was worse for employees with high scores for performance goal orientation, although they rated themselves and were rated by their supervisors as good performers. Such profiles can only be uncovered when different performance indicators are considered simultaneously.

- Abstract
Acute dystonia is a side-effect associated with the use of antipsychotics. We describe the case of a 75-year-old patient with late-onset schizophrenia who used clozapine. During a hospital admission due to pneumonia, she developed a form of acute dystonia consisting of a rotational torticollis, which disappeared rapidly after treatment with biperiden. Blood examination showed an increase of the clozapine level, probably due to the infection. This case report shows that acute dystonia, although very rare, can occur during treatment with clozapine; therefore awareness is needed of the circumstances that can alter clozapine levels.

- Abstract
We investigated the impact of subconscious goals on academic performance in two field experiments. We show that unobtrusive priming of goals with regard to achievement motivation by means of a photograph improves performance in different educational contexts. High-school students who were exposed to an achievement-related photograph achieved higher grades than students in two control conditions. This effect was not affected by students’ prior performance. University students exposed to a photograph representing a specific, difficult goal reached even higher performance than students taking the exam with a general achievement photograph. For practice, subconscious goals may form a powerful, cost-effective tool to enhance academic performance. However, varying results across the experiments also prompt the need for further investigations of such effects

- Abstract
Finding reemployment after job loss is a complex and difficult task that requires extensive motivation and self-regulation. This study aimed to examine whether improving unemployed job seekers’ cognitive self-regulation can increase reemployment probabilities. Based on the goal orientation literature, we developed a learning-goal orientation (LGO) training, which focused on goal setting aimed at improving rather than demonstrating competences and creating a climate of development and improvement. We predicted that the LGO training would influence peoples’ goal orientation towards job seeking, which in turn would relate to learning from failure, strategy awareness, and self-efficacy, leading to job-search intentions, resulting in increased reemployment status. Using a 2-group quasi-experimental design with 223 unemployed job seekers, we found support for these predictions, except for self-efficacy. The results suggest that an LGO training is a promising tool to improve self-regulation in and effectiveness of job search.

- Abstract
Workplace violence is a major occupational hazard for healthcare workers, generating a need for effective intervention programs. The purpose of this study was to evaluate the effectiveness of an aggression management training program. The evaluation design was based on the internal referencing strategy, an unobtrusive and applicable evaluation method that rules out some major threats to internal validity without the need for a control group. On three occasions, training participants completed a questionnaire containing experimental and control variables. As hypothesized, there was a significant improvement in the experimental variables that was larger than the non-significant change in the control variable. We conclude that aggression management training may be an effective instrument in the fight against workplace violence. © 2008 Wiley Periodicals, Inc.

Aim: To compare candesartan cilexetil and lisinopril in fixed combination with hydrochlorothiazide with respect to antihypertensive efficacy and tolerability. Methods: This was a double-blind (double-dummy), randomised, parallel group comparison in patients with a mean sitting diastolic blood pressure 95-115 mm Hg on prior antihypertensive monotherapy. Treatments were candesartan cilexetil/hydrochlorothiazide 8/12.5 mg once daily (n = 237) and lisinopril/hydrochlorothiazide 10/12.5 mg once daily (n = 116) for 26 weeks. The primary efficacy variable was change in trough sitting diastolic blood pressure. Results: Changes in mean sitting diastolic blood pressure did not differ significantly between the groups (mean difference 0.5 mm Hg; 95% confidence interval -1.6, 2.7, P = 0.20). No significant differences between the groups was found for other haemodynamic variables (sitting systolic blood pressure, standing blood pressure, sitting/erect heart rate, and proportion of responders and controlled patients). Both drugs were well tolerated but the proportion of patients with at least one adverse event was significantly greater in the lisino-pril group (80% vs 69%, P = 0.020). The proportion of patients spontaneously reporting cough (23.1% vs 4.6%) and discontinuing therapy due to adverse events (12.0% vs 5.9%) was also higher in the lisinopril group compared with the candesartan cilexetil group. Conclusions: The fixed combinations of candesartan cilexetil and hydrochlorothiazide 8/12.5 mg and lisino-pril and hydrochlorothiazide 10/12.5 mg once daily are equally effective as antihypertensive agents. The fixed combination containing candesartan cilexetil is better tolerated than that containing lisinopril. [ABSTRACT FROM AUTHOR]

ANTIHYPERTENSIVE agents ,REGULATION of blood pressure ,DRUG efficacy - Abstract
Monotherapy with an antihypertensive agent is likely to achieve a desirable lowering of blood pressure in about 50% of patients. The remaining proportion of patients are likely to be only partially responsive or unresponsive, even if appropriate dose adjustments are made. For these patients, combination therapy usually leads to better control of hypertension. The aim of this study was to compare the antihypertensive effect and tolerability of a once-daily combination of the angiotensin II type 1 (AT1) receptor blocker candesartan cilexetil, 8 mg, and the diuretic hydrochlorothiazide (HCTZ), 12.5 mg, with a combination of the angiotensin-converting enzyme inhibitor, lisinopril, 10 mg, and HCTZ, 12.5 mg, in patients with primary hypertension. The study included men and women, 20-80 years of age, with sitting diastolic blood pressure (DBP) of 95-114 mm Hg. After a run-in period of 2 weeks on any antihypertensive monotherapy, 355 patients were randomized to double-blind treatment with either a combination of candesartan cilexetil/HCTZ, 8/12.5 mg, or a combination of lisinopril/HCTZ, 10/12.5 mg, for 26 weeks. Blood pressure was measured 24 h after dose intake, the primary efficacy variable being the change in sitting DBP at trough between baseline and 26 weeks of treatment. Reductions in mean sitting DBP after 26 weeks were similar for both combination treatments. In addition, no differences were found between the two treatment groups regarding standing DBP, sitting and standing systolic blood pressure, heart rate, and the proportion of responders and controlled patients. Significantly fewer patients reported at least one adverse event with candesartan cilexetil/HCTZ than with lisinopril/HCTZ (68.9% vs 79.5%, p = 0.02; see Table). Furthermore, the proportion of patients spontaneously reporting cough was markedly higher in the lisinopril/HCTZ group (23.9%) than in the candesartan cilexetil/HCTZ group (5.0%). Thus, although the combinations of candesartan cilexetil/HCTZ, 8/12.5 mg once daily, and lisinopril/HCTZ, 10/12.5 mg once daily, had similar antihypertensive efficacy in patients with mild to moderate hypertension during the 26-week treatment period, candesartan cilexetil/HCTZ was significantly better tolerated than lisinopril/HCTZ.

- Abstract
Objective: Although repetitive transcranial magnetic stimulation (rTMS) is an effective treatment for depression, little is known about the comparative effectiveness of rTMS and other treatment options, such as antidepressants. In this multicenter randomized controlled trial, rTMS was compared with the next pharmacological treatment step in patients with treatment-resistant depression., Methods: Patients with unipolar nonpsychotic depression (N=89) with an inadequate response to at least two treatment trials were randomized to treatment with rTMS or to a switch of antidepressants, both in combination with psychotherapy. Treatment duration was 8 weeks and consisted of either 25 high-frequency rTMS sessions to the left dorsolateral prefrontal cortex or a switch of antidepressant medication following the Dutch treatment algorithm. The primary outcome was change in depression severity based on the Hamilton Depression Rating Scale (HAM-D). Secondary outcomes were response and remission rates as well as change in symptom dimensions (anhedonia, anxiety, sleep, rumination, and cognitive reactivity). Finally, expectations regarding treatment were assessed., Results: rTMS resulted in a significantly larger reduction in depressive symptoms than medication, which was also reflected in higher response (37.5% vs. 14.6%) and remission (27.1% vs. 4.9%) rates. A larger decrease in symptoms of anxiety and anhedonia was observed after rTMS compared with a switch in antidepressants, and no difference from the medication group was seen for symptom reductions in rumination, cognitive reactivity, and sleep disorders. Expectations regarding treatment correlated with changes in HAM-D scores., Conclusions: In a sample of patients with moderately treatment-resistant depression, rTMS was more effective in reducing depressive symptoms than a switch of antidepressant medication. In addition, the findings suggest that the choice of treatment may be guided by specific symptom dimensions., Competing Interests: The Netherlands Trial Register: NL7628 (https://trialsearch.who.int/Trial2.aspx?TrialID=NL-OMON24799).The data sets that were used for this study are available in the Radboud Repository (https://repository.ubn.ru.nl/).Dr. Arns holds equity or stock in Neurocare and Sama Therapeutics; he has served as a consultant for Neurocare, Roche, Sama Therapeutics, and Synaeda; and he is a named inventor on patents and intellectual property.

- Abstract
Background: Major depressive disorder (MDD) is one of the most common psychiatric disorders, however, current treatment options are insufficiently effective for about 35% of patients, resulting in treatment-resistant depression (TRD). Repetitive transcranial magnetic stimulation (rTMS) is a form of non-invasive neuromodulation that is effective in treating TRD. Not much is known about the comparative efficacy of rTMS and other treatments and their timing within the treatment algorithm, making it difficult for the treating physician to establish when rTMS is best offered as a treatment option. This study aims to investigate the (cost-)effectiveness of rTMS (in combination with cognitive behavioral therapy (CBT) and continued antidepressant medication), compared to the next step in the treatment algorithm. This will be done in a sample of patients with treatment resistant non-psychotic unipolar depression., Methods: In this pragmatic multicenter randomized controlled trial 132 patients with MDD are randomized to either rTMS or the next pharmacological step within the current treatment protocol (a switch to a tricyclic antidepressant or augmentation with lithium or a second-generation antipsychotic). Both groups also receive CBT. The trial consists of 8 weeks of unblinded treatment followed by follow-up of the cohort at four and 6 months. A subgroup of patients (n = 92) will have an extended follow-up at nine and 12 months to assess effect decay or retention. We expect that rTMS is more (cost-)effective than medication in reducing depressive symptoms in patients with TRD. We will also explore the effects of both treatments on symptoms associated with depression, e.g. anhedonia and rumination, as well as the effect of expectations regarding the treatments on its effectiveness., Discussion: The present trial aims to inform clinical decision making about whether rTMS should be considered as a treatment option in patients with TRD. The results may improve treatment outcomes in patients with TRD and may facilitate adoption of rTMS in the treatment algorithm for depression and its implementation in clinical practice., Trial Registration: This trial is registered within the Netherlands Trial Register (code: NL7628 , date: March 29th 2019)., (© 2022.

- Abstract
Background: Psychiatric disorders are associated with a more severe course of COVID-19. COVID-19 can also lead to psychiatric symptoms., Aim: To gain insight into vulnerabilities and protective factors for the course of COVID-19 in a Dutch (neuro)psychiatric population., Method: Patients were divided into three groups: patients with pre-existent mental disorders without and with new (neuro)psychiatric symptoms (NPS) during COVID-19 and patients without pre-existent mental disorders who developed de novo NPS during COVID-19. We summarize the characteristics of each group and compare the subgroups with inferential statistics., Results: 186 patients were included in the case register. Patients with NPS showed a more severe course of COVID-19. Mortality in patients with NPS was higher in patients with pre-existent mental disorders compared to patients without pre-existent mental disorders. The most frequently reported de novo psychiatric symptoms during COVID-19 were delirium (46-70%), anxiety (53-54%) and insomnia (18-42%)., Conclusion: NPS might be an expression of a more severe COVID-19 episode. In patients who developed NPS during COVID-19 we found evidence for a higher mortality risk in patients with pre-existent mental disorders. Extra vigilance for neuropsychiatric symptoms during COVID-19 is warranted.

- Abstract
Many employees worldwide combine a job with serious, goal-oriented ambitions in the athletic domain. However, scientific knowledge about day-to-day linkages between work and sports is lacking. We filled this gap in the literature by examining how experiences at work can enrich sports after work. Extending the work-home resources model to the work-sports interface, we posited that proactive work behaviors positively relate to work engagement - a state that may permeate into the sports domain and relate to positive sports outcomes. We conducted a diary study among 170 working recreational runners (598 measurement occasions). Within a three-week period, participants completed two surveys on days they worked and ran after work. Survey 1, completed at the end of the workday, covering proactive work behavior and work engagement, and survey 2, completed after running and covering running performance. The results of multilevel structural equation modeling indicated that on days employees showed more proactive behavior, they also reported higher work engagement. In turn, on days they reported higher work engagement, they recorded a steadier running pace. We discuss how these findings support the phenomenon of work-to-sports spillover and contribute to the current understanding of the interplay between work and sports.

- Abstract
In 2019 the Canadian Space Agency initiated development of a dedicated wildfire monitoring satellite (WildFireSat) mission. The intent of this mission is to support operational wildfire management, smoke and air quality forecasting, and wildfire carbon emissions reporting. In order to deliver the mission objectives, it was necessary to identify the technical and operational challenges which have prevented broad exploitation of Earth Observation (EO) in Canadian wildfire management and to address these challenges in the mission design. In this study we emphasize the first objective by documenting the results of wildfire management end-user engagement activities which were used to identify the key Fire Management Functionalities (FMFs) required for an Earth Observation wildfire monitoring system. These FMFs are then used to define the User Requirements for the Canadian Wildland Fire Monitoring System (CWFMS) which are refined here for the WildFireSat mission. The User Requirements are divided into Observational, Measurement, and Precision requirements and form the foundation for the design of the WildFireSat mission (currently in Phase-A, summer 2020).

- Abstract
Demyelinated lesions of the central nervous system are characteristic for multiple sclerosis (MS). Remyelination is not very effective, particular at later stages of the disease, which results in a chronic neurodegenerative character with worsening of symptoms. Previously, we have shown that the enzyme Tissue Transglutaminase (TG2) is downregulated upon differentiation of oligodendrocyte progenitor cells (OPCs) into myelin-forming oligodendrocytes and that TG2 knock-out mice lag behind in remyelination after cuprizone-induced demyelination. Here, we examined whether astrocytic or oligodendroglial TG2 affects OPCs in a cell-specific manner to modulate their differentiation, and therefore myelination. Our findings indicate that human TG2-expressing astrocytes did not modulate OPC differentiation and myelination. In contrast, persistent TG2 expression upon OPC maturation or exogenously added recombinant TG2 accelerated OPC differentiation and myelin membrane formation. Continuous exposure of recombinant TG2 to OPCs at different consecutive developmental stages, however, decreased OPC differentiation and myelin membrane formation, while it enhanced myelination in dorsal root ganglion neuron-OPC co-cultures. In MS lesions, TG2 is absent in OPCs, while human OPCs show TG2 immunoreactivity during brain development. Exposure to the MS-relevant pro-inflammatory cytokine IFN-γ increased TG2 expression in OPCs and prolonged expression of endogenous TG2 upon differentiation. However, despite the increased TG2 levels, OPC maturation was not accelerated, indicating that TG2-mediated OPC differentiation may be counteracted by other pathways. Together, our data show that TG2, either endogenously expressed, or exogenously supplied to OPCs, accelerates early OPC differentiation. A better understanding of the role of TG2 in the OPC differentiation process during MS is of therapeutic interest to overcome remyelination failure.

33. When Teams Fail to Self-Regulate: Predictors and Outcomes of Team Procrastination Among Debating Teams.

- Abstract
Models of team development have indicated that teams typically engage in task delay during the first stages of the team's life cycle. An important question is to what extent this equally applies to all teams, or whether there is variation across teams in the amount of task delay. The present study introduces the concept of team procrastination as a lens through which we can examine whether teams collectively engage in unplanned, voluntary, and irrational delay of team tasks. Based on theory and research on self-regulation, team processes, and team motivation we developed a conceptual multilevel model of predictors and outcomes of team procrastination. In a sample of 209 student debating teams, we investigated whether and why teams engage in collective procrastination as a team, and what consequences team procrastination has in terms of team member well-being and team performance. The results supported the existence of team procrastination as a team-level construct that has some stability over time. The teams' composition in terms of individual-level trait procrastination, as well as the teams' motivational states (i.e., team learning goal orientation, team performance-approach goal orientation in interaction with team efficacy) predicted team procrastination. Team procrastination related positively to team members' stress levels, especially for those low on trait procrastination. Furthermore, team procrastination had an indirect negative relationship with team performance, through teams' collective stress levels. These findings add to the theoretical understanding of self-regulatory processes of teams, and highlight the practical importance of paying attention to team-level states and processes such as team goal orientation and team procrastination.

- Abstract
Acute dystonia is a side-effect associated with the use of antipsychotics. We describe the case of a 75-year-old patient with late-onset schizophrenia who used clozapine. During a hospital admission due to pneumonia, she developed a form of acute dystonia consisting of a rotational torticollis, which disappeared rapidly after treatment with biperiden. Blood examination showed an increase of the clozapine level, probably due to the infection. This case report shows that acute dystonia, although very rare, can occur during treatment with clozapine; therefore awareness is needed of the circumstances that can alter clozapine levels.

- Abstract
Slepian, Masicampo, Toosi, and Ambady (2012, Experiment 1) reported that participants who recalled a big secret estimated a hill as steeper than participants who recalled a small secret. This finding was interpreted as evidence that secrets are experienced as physical burdens. In 2 experiments, we tried to replicate this finding, but, despite larger power, did not find a difference in slant estimates between participants who recalled a big secret and those who recalled a small secret. This finding was further corroborated by a meta-analysis that included 8 published data sets of exact replications, which indicates that thinking of a big secret does not affect hill slant estimation. In a third experiment, we also failed to replicate the effect of recalling a secret on throwing a beanbag at a target (Slepian et al., 2012, Experiment 2). Together, our findings question the robustness of the original empirical findings., ((c) 2015 APA, all rights reserved).)

- Abstract
Background: Our knowledge about auto-immune limbic encephalitis is increasing rapidly and it is now evident that patients with this disease can present with psychiatric symptoms., Aim: To propose practical guidelines for the recognition and diagnosis of an underlying auto-immune limbic encephalitis in patients with acute psychiatric symptoms., Method: We studied recent reviews on the topic and had discussions with psychiatrists, a neurologist and a neuroimmunologist in order to reach consensus., Results: Auto-immune limbic encephalitis is a rather rare but important diagnostic consideration in patients with acute psychiatric symptoms. We describe the different steps in the diagnostic work-up and mention features that can point to an underlying auto-immune encephalitis. These include atypical psychiatric symptoms, seizures, movement disorders and autonomic instability., Conclusion: Since patients with autoimmune limbic encephalitis often present with psychiatric symptoms, curative treatment is often available and the prognosis depends on the delay from presentation to treatment, psychiatrists should be aware of the signs of an underlying autoimmune encephalitis which have been described in this article.

- Abstract
In this diary study, we examined the associations between daily work-related smartphone use and daily psychological detachment and daily work-related exhaustion within a group of smartphone owners. In addition, we studied the role of the perceived segmentation norm at the workplace as a moderator of the link between work-related smartphone use and detachment. A total of 70 employees using smartphones on initiative of their employer completed a diary questionnaire on 4 successive workdays (N = 268 data points). We hypothesized that work-related smartphone use is negatively related to psychological detachment and that psychological detachment, in turn, is negatively related to work-related exhaustion. Finally, we expected that especially employees who perceive a high segmentation norm at their workplace have difficulties to psychologically detach from work on days that they use their smartphone more intensively. Overall, the results of multilevel analyses supported these hypotheses. The findings emphasize the importance of a clear organizational policy regarding work-related smartphone use outside of work hours., (PsycINFO Database Record (c) 2014 APA, all rights reserved.)

- Abstract
Updating and extending the work of O'Leary-Kelly, Martocchio, and Frink (1994), with this meta-analysis on goal setting and group performance we show that specific difficult goals yield considerably higher group performance compared with nonspecific goals (d = 0.80 ± 0.35, k = 23 effect sizes). Moderately difficult and easy goals were also associated with performance benefits relative to nonspecific goals, but these effects were smaller. The overall effect size for all group goals was d = 0.56 ± 0.19 (k = 49). Unexpectedly, task interdependence, task complexity, and participation did not moderate the effect of group goals. Our inventory of multilevel goals in interdependent groups indicated that the effect of individual goals in groups on group performance was contingent upon the focus of the goal: "Egocentric" individual goals, aimed at maximizing individual performance, yielded a particularly negative group-performance effect (d = -1.75 ± 0.60, k = 6), whereas "groupcentric" goals, aimed at maximizing the individual contribution to the group's performance, showed a positive effect (d = 1.20 ± 1.03, k = 4). These findings demonstrate that group goals have a robust effect on group performance. Individual goals can also promote group performance but should be used with caution in interdependent groups. Future research might explore the role of multilevel goals for group performance in more detail. The striking lack of recent field studies in organizational settings that emerged from our brief review of trends in group goal-setting research should be taken into account when designing future studies in this domain., ((c) 2011 APA, all rights reserved.)

- Abstract
Aim: To compare candesartan cilexetil and lisinopril in fixed combination with hydrochlorothiazide with respect to antihypertensive efficacy and tolerability., Methods: This was a double-blind (double-dummy), randomised, parallel group comparison in patients with a mean sitting diastolic blood pressure 95-115 mm Hg on prior antihypertensive monotherapy. Treatments were candesartan cilexetil/hydrochlorothiazide 8/12.5 mg once daily (n = 237) and lisinopril/hydrochlorothiazide 10/12.5 mg once daily (n = 116) for 26 weeks. The primary efficacy variable was change in trough sitting diastolic blood pressure., Results: Changes in mean sitting diastolic blood pressure did not differ significantly between the groups (mean difference 0.5 mm Hg; 95% confidence interval -1.6, 2.7, P = 0.20). No significant differences between the groups was found for other haemodynamic variables (sitting systolic blood pressure, standing blood pressure, sitting/erect heart rate, and proportion of responders and controlled patients). Both drugs were well tolerated but the proportion of patients with at least one adverse event was significantly greater in the lisinopril group (80% vs 69%, P = 0.020). The proportion of patients spontaneously reporting cough (23.1% vs 4.6%) and discontinuing therapy due to adverse events (12.0% vs 5.9%) was also higher in the lisinopril group compared with the candesartan cilexetil group., Conclusions: The fixed combinations of candesartan cilexetil and hydrochlorothiazide 8/12.5 mg and lisinopril and hydrochlorothiazide 10/12.5 mg once daily are equally effective as antihypertensive agents. The fixed combination containing candesartan cilexetil is better tolerated than that containing lisinopril.
