- This study examined relationships between authentic leadership and safety climateamong 463 seafarers sailing on 23 merchant vessels in the international shipping industry. A multiple regression analysis was performed, where authentic leadership made a statistically significant contribution to explaining variance in safety climate, controlling for age, rank on board, and social desirable responding. Adding an interaction between authentic leadership and rank on board (officers vs. crew) to the multiple regression analysis did not add to the amount of explained variance (R 2 = .38). Implications for leadership training and safety in shipping are discussed.

- Based on the impact of the theoretical big five of teamwork model proposed by Salas et al. (2005), the present study aimed at investigating the model within an operational police simulation. One hundred and sixty-seven frontline police officers participated in the study. Based on path analyses, a reduced model excluding trust and leadership obtained a good fit with the data.The results provided some support for the model by confirming six out of 10 proposed direct effects and four out of seven indirect pathways. Shared mental models directly affected team adaptability, and backup behavior affects adaptability and team effectiveness. Team orientation affects mutual performance monitoring and backup behavior, and finally, reciprocal monitoring affects backup behavior. Monitoring influenced both team effectiveness and adaptability through backup behavior. Two paths from team orientation towards effectiveness were found. One flowing through monitoring and another through back-up behavior. Our study expands former knowledge of the big five theory by empirically testing the totality of the model and identifying important pathways.

- Insomnia is a substantial problem in patients with obsessive-compulsive disorder (OCD). There is, however, a lack of studies investigating changes in concurrent symptoms of insomnia in OCD after concentrated treatment. A recent randomized controlled trial randomized participants to the Bergen 4-day treatment (B4DT, n = 16), or 12 weeks of unguided self-help (SH, n = 16), or waitlist (WL, n = 16). Patients from the SH- and WL-group who wanted further treatment after the 12 weeks were then offered the B4DT (total of 42 patients treated with the B4DT). There were no significant differences in symptoms of insomnia between the conditions at post-treatment, but a significant moderate improvement at 3-month follow-up for patients who received the B4DT. Insomnia was not associated with OCD-treatment outcome, and change in symptoms of insomnia was mainly related to changes in depressive symptoms. The main conclusion is that concentrated exposure treatment is effective irrespective of comorbid insomnia, and that insomnia problems are moderately reduced following treatment.

The Effect of Complexity of Ambulance Missions on Shared Mental Models in Virtual Teams
- 2022
-
Ingår i: Emergency Medicine Open Journal. - 2379-4046. ; 8:1, s. 25-31
-
Tidskriftsartikel (refereegranskat)abstract
- Background Empirical research on shared mental models (SMM) in virtual environments are almost non-existent. Pre-hospital emergencies presents an opportunity to examine team processes in virtual teams because the dispatcher is geographically separated from the ambulance and at the same time plays a significant role in coordinating, organizing, obtaining, evaluating, and conveying relevant information to the deployed ambulance. The present study aimed at mapping team behavior and cognition in critical real-life emergency medical missions based on the concept of SMM. Methods By investigating the frequencies of coordinating mechanisms and team competencies based on voice recordings from real-life missions, differences in team behavior between low and high-complexity missions were investigated. Results Lower frequencies of team competencies and coordinating mechanisms were found in high compared to low-complexity missions. The results showed a different profile in communication between high and low-complexity missions with more frequent use of both coordinating mechanisms and team competencies in low-complexity missions. Furthermore, the profiles revealed that SMM and closed loop communication were the only coordinating mechanism used, and leadership and team orientation were the only competencies exercised. Conclusion It was concluded that the lack of visual input of a team member during team interaction could lead to team process loss due to a breakdown of the team into sub-units. Potential improvement of team behavior is discussed within the SMM framework.

Concentrated transdiagnostic and cross-disciplinary group treatment for patients with depression and with anxiety : a pilot study
- 2022
-
Ingår i: BMC Psychiatry. - : Springer Science and Business Media LLC. - 1471-244X. ; 22:1
-
Tidskriftsartikel (refereegranskat)abstract
- Background: A number of treatment approaches have shown efficacy for depression and/or anxiety, yet there is a paucity of research on potentially cost-effective concentrated approaches. Based on our previous experience with concentrated treatment in disorders such as Obsessive–Compulsive Disorder and chronic fatigue, we proposed that this novel approach could be useful for other conditions, including depression and/or anxiety. As a pre-requisite for a future randomized controlled trial, the aim of this study was to investigate the acceptability, satisfaction and effectiveness of a transdiagnostic, interdisciplinary group treatment delivered during 5 consecutive days to groups of 6–10 patients with depression and/or anxiety.Methods: This was a non-randomized clinical intervention pilot study in line with a published protocol. Forty-two consecutively referred patients, aged 19–47 (mean age 31.7, SD = 8.12) were included and completed treatment. All had a severity of their problems that entitled them to care in the specialist public mental health care. Self-reported age when the symptoms became a problem was 20.9 years. Mean number of prior treatment courses was 2.77 (SD = 2.19; range 0–8). Acceptability was defined as the proportion of eligible patients who accepted and completed the treatment. Satisfaction was evaluated by Client Satisfaction Questionnaire-8. Secondary objectives were to assess the treatment effectiveness by questionnaires at pre-treatment, seven days post-treatment and three months follow-up.Results: The treatment was highly acceptable (91.3% accepted, all completed), and patients were highly satisfied with the treatment, including the amount. Functional impairment, as measured by Work and Social Adjustment Scale (WSAS) improved significantly (p < .0005) from “severe” (mean 25.4 SD = 6.59) to “less severe” (mean 13.37, SD = 9.43) at 3 months follow-up. Using the Generalized Anxiety Disorder Scale (GAD-7) and the Patient Health Questionnaire (PHQ-9), the effect sizes at 3 months follow-up were 1.21 for anxiety and 1.3 for depression. More than 80% reported reduced utilization of mental health care, and 67% had not used, or had used the family doctor less, for anxiety or depression. 52% had not used, or had reduced, medication for their disorder.Conclusions: The concentrated, interdisciplinary treatment approach yielded promising results. Long-term follow up is warranted.

Effect of D-Cycloserine on the Effect of Concentrated Exposure and Response Prevention in Difficult-to-Treat Obsessive-Compulsive Disorder : A Randomized Clinical Trial
- 2020
-
Ingår i: JAMA Network Open. - : American Medical Association (AMA). - 2574-3805. ; 3:8

Tidskriftsartikel (refereegranskat)abstract
- IMPORTANCE: Evidence is lacking for viable treatment options for patients with difficult-to-treat obsessive-compulsive disorder (OCD). It has been suggested that D-cycloserine (DCS) could potentiate the effect of exposure and response prevention (ERP) treatment, but the hypothesis has not been tested among patients with difficult-to-treat OCD.OBJECTIVE: To evaluate whether DCS potentiates the effect of concentrated ERP among patients with difficult-to-treat OCD.DESIGN, SETTING, AND PARTICIPANTS: The study was a randomized placebo-controlled triple-masked study with a 12-month follow-up. Participants were adult outpatients with difficult-to-treat OCD. A total of 220 potential participants were referred, of whom 36 did not meet inclusion criteria and 21 declined to participate. Patients had either relapsed after (n = 100) or not responded to (n = 63) previous ERP treatment. A total of 9 specialized OCD teams within the public health care system in Norway participated, giving national coverage. An expert team of therapists from the coordinating site delivered treatment. Inclusion of patients started in January 2016 and ended in August 2017. Data analysis was conducted February to September 2019.INTERVENTIONS: All patients received individual, concentrated ERP treatment delivered during 4 consecutive days in a group setting (the Bergen 4-day treatment format) combined with 100 mg DCS, 250 mg DCS, or placebo.MAIN OUTCOMES AND MEASURES: Change in symptoms of OCD and change in diagnostic status. Secondary outcomes measures included self-reported symptoms of OCD, anxiety, depression, and quality of life.RESULTS: The total sample of 163 patients had a mean (SD) age of 34.5 (10.9) years, and most were women (117 [71.8%]). They had experienced OCD for a mean (SD) of 16.2 (10.2) years. A total of 65 patients (39.9%) were randomized to receive 100 mg DCS, 67 (41.1%) to 250 mg of DCS, and 31 (19.0%) to placebo. Overall, 91 (56.5%) achieved remission at posttreatment, while 70 (47.9%) did so at the 12-month follow-up. There was no significant difference in remission rates among groups. There was a significant reduction in symptoms at 12 months, and within-group effect sizes ranged from 3.01 (95% CI, 2.38-3.63) for the group receiving 250 mg DCS to 3.49 (95% CI, 2.78-4.18) for the group receiving 100 mg DCS (all P < .001). However, there was no significant effect of treatment group compared with placebo in obsessive-compulsive symptoms (250 mg group at posttreatment: d = 0.33; 95% CI, -0.10 to 0.76; 100 mg group at posttreatment: d = 0.36; 95% CI, -0.08 to 0.79), symptoms of depression and anxiety (eg, Patient Health Questionnaire-9 score among 250 mg group at 12-month follow-up: d = 0.30; 95% CI, -0.17 to 0.76; Generalized Anxiety Disorder-7 score among 100 mg group at 12-month follow-up: d = 0.27; 95% CI, -0.19 to 0.73), and well-being (250 mg group: d = 0.10; 95% CI, -0.42 to 0.63; 100 mg group: d = 0.34; 95% CI, -0.19 to 0.86). No serious adverse effects were reported.CONCLUSIONS AND RELEVANCE: In this study, DCS did not potentiate ERP treatment effect, but concentrated ERP treatment was associated with improvement. This randomized clinical trial evaluates whether D-cycloserine potentiates the effect of concentrated exposure and response prevention among patients with difficult-to-treat obsessive-compulsive disorder.

Tidskriftsartikel (refereegranskat)abstract
- Background: The Bergen 4-day treatment (B4DT) is a concentrated exposure-based treatment for patients with Obsessive-Compulsive Disorder (OCD) delivered during four consecutive days. The B4DT has in a number of effectiveness studies demonstrated promising results as approximately 90% of patients gain reliable clinical change post-treatment and nearly 70% are recovered on a long-term basis.Methods: The current study is the first randomized controlled trial evaluating the effects of the B4DT. Forty-eight patients diagnosed with OCD were randomized to B4DT, self-help (SH), or waiting list (WL) with 16 patients in each condition. All participants randomized to the B4DT underwent the treatment without any attrition.Results: The B4DT yielded significantly better effects than control conditions on measures of OCD, depression, and generalized anxiety. The response rate (≥35% reduction of the individual patient’s pre-treatment Y-BOCS score) was 93.8% in B4DT, 12.5% in SH and 0% in WL, while remission rate (response criterion is fulfilled and the post-treatment Y-BOCS score is ≤12 points) was 62.5%, 6.3%, and 0%, respectively. Furthermore, patients who had received the B4DT, showed improved work- and social functioning. None of the patients treated with B4DT showed signs of deterioration. In comparison, one patient in the SH condition was in remission, and one showed significant clinical improvement, whereas the remaining showed no change.Conclusion: The results indicate that the B4DT is an effective treatment for patients suffering from OCD.Clinical Trial Registration: www.ClinicalTrials.gov, identifier NCT02886780.

Exploring Why Police and Military Commanders Do What They Do : An Empirical Analysis of Decision-Making in Hybrid Warfare
- 2023

Tidskriftsartikel (refereegranskat)abstract
- In this study, a total of 102 high-ranking commanders from a military and police background were included in a simulation involving hybrid attacks on Norway. The aim was to explore the commanders’ decision-making in the context of hybrid warfare and changing threats. Data were collected in a simulated national headquarters and analyzed by a multinominal logistic regression method using a scenario that transformed from peacetime into war and returned to peace. The results demonstrated significant differences in the commanders’ preferences for unilateral or interagency forces depending on whether decisions were made in peacetime, war or the post-conflict phase. The results also showed how the commanders’ level of operational experience was associated with an increased preference for interagency forces. The current findings are new empirical insights into a thus far neglected aspect of decision-making research and have implications for improving police-military interoperability in major security crises.
