Ship Leadership, Situation Awareness, and Crew Safety Behaviour—Preregistered Replications in Two Survey Datasets

Situation awareness is often assumed to be crucial for working safely. Self-reported context-general measures can be an efficient way to measure situation awareness in large datasets and test how it relates to other individual, organizational, and environmental variables. In a previous structural equation model (Sætrevik & Hystad, 2017) authentic leadership accounted for situation awareness and self-report of committing unsafe actions, while situation awareness accounted for subjective risk assessment and commitment of unsafe actions. The current study performed preregistered replications of the same associations in two novel but similar datasets. Both datasets replicated that higher situation awareness was associated with fewer unsafe actions and with lower subjective risk assessment. One of the new datasets measured leadership, and more authentic leadership was found to be associated with higher situation awareness and fewer unsafe actions. The preregistered structural equation models explained large amounts of the variance in situation awareness and unsafe actions and medium to large amounts of the variance in subjective risk assessment. We also tested adjusted models that incorporated more of the measured items and improved the validity of the measures. The study supports the claim that a crewmember’s cognitive states (such as perception, understanding, and prediction of safety signals) are associated with safety outcomes and that leadership qualities may facilitate this relationship. This preregistered replication in two novel datasets increases the reliability of the previously identified relationships.publishedVersio

The dimensionality of the 12-item general health questionnaire (GHQ-12): Comparisons of factor structures and invariance across samples and time

Because of its brevity, the 12-item General Health Questionnaire (GHQ-12) has become one of the most popular and used measure for detecting psychological distress. Originally intended as a unidimensional measure, the majority of subsequent factor-analytic studies have failed to support GHQ-12 as a unitary construct and have instead proposed a plethora of multidimensional structures. In this study, we further examined the factor structure in two different military samples, one consisting of crewmembers from four different frigates deployed in anti-piracy operations and Standing NATO Maritime Group deployments (N = 591) and one consisting of crewmember from three different minehunters/sweepers serving in Standing NATO Mine Counter-Measures Group deployments (N = 196). Results from confirmatory factor analyses (CFA) performed in the first sample supported a bifactor model, consisting of a general factor representing communality among all items and two specific factors reflecting common variance due to wording effects (negatively and positively phrased items). A multi-group CFA further confirmed this structure to be invariant across our second sample. Structural equation modeling also showed that the general factor was strongly associated with symptoms of insomnia and mental health, whereas the specific factors were either non-significantly or considerably weaker associated with the criterion variables. Overall, our results are congruent with the notion that the multidimensionality demonstrated in many previous investigations is most likely an expression of method-specific variance caused by item wording. The explained unique variance associated with these specific factors was further relatively small. Ignoring the multidimensionality and treating GHQ-12 as a unitary construct will therefore most likely introduce minimal bias to most practical applications.publishedVersio

Police Dyads Within an Operational Simulation: an Empirical Test of the Research Propositions Made in the “Big Five” Teamwork Approach

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.publishedVersio

Do Ideals Differ and Matter? An Investigation of Authentic Leadership Ideals Among Norwegian Military Officers Across Generations – and Its Impact on Leadership Practice

The aim of the present study was to learn more about the content of leadership ideals among Norwegian military officers, and to what degree such ideals influence the officers’ actual leadership practice. We have also explored possible generational differences between generation X officers (born between 1965 and 1980) and generation Y officers (born between 1980 and 1998) related to leadership ideals. The sample consisted of 117 younger and 91 older Norwegian officers. The ideals framing the study were operationalized as authentic leadership (AL), portrayed in the literature as an ideal form of leadership. The results showed that the officers in both generations perceived all dimensions of AL as ideal. Younger officers, however, perceived an internalized moral perspective and balanced processing as less ideal than their older colleagues. No relationship between AL ideals and practice was found for the sample, after controlling for the effect of self-evaluations. However, the results indicated a positive influence of ideals among the young officers. These results are discussed in relation to the existing literature and practical implications. Suggestions for future studies are also outlined.publishedVersio

Fatigue in seafarers working in the offshore oil and gas re-supply industry: effects of safety climate, psychosocial work environment and shift arrangement

This study examined the influence of safety climate and psychosocial work environment on the reported fatigue of seafarers working in the offshore oil and gas re-supply industry (n = 402). We found that seafarers who reported high psychological demands and perceived the organisational-level safety climate negatively, reported significantly more mental fatigue, physical fatigue, and lack of energy. In addition, seafarers who reported having high levels of job control reported being significantly less mentally fatigued. We also found some combined effects of safety climate and shift arrangement. Organisational-level safety climate did not influence the levels of physical fatigue in seafarers working on the night shift. On the contrary, seafarers working during the days reported to be more physically fatigued when they perceived the organisational-level climate to be negative compared with the positive. The opposite effect was found for group-level safety climate: seafarers working during the nights reported to be more physically fatigued when they perceived the group-level climate to be negative compared with the positive. The results from this study point to the importance of taking into consideration aspects of the psychosocial work environment and safety climate, and their potential impact on fatigue and safety in the maritime organisations.publishedVersio

The effect of hardiness on symptoms of insomnia during a naval mission

Background: Sleep is increasingly being recognised as important for the health and well-being of sailors. The aim of the current study is to investigate the relationship between hardiness and reported insomnia-symptoms in a maritime military setting during a 4-month counter piracy naval mission in the Gulf of Aden. Materials and methods: A sample of 281 officers, sailors, and enlisted personnel were measured on levels of hardiness before the mission. The participants were split into low and high hardiness groups based on the group level mean. Insomnia-symptoms were measured before, midway and at the end of the mission. Results: The results showed a significant main effect of time and a significant main effect of hardiness. The crew experienced the most insomnia symptoms in the middle of the mission and the high hardy group experienced less insomnia symptoms, in total, during the mission. There was also found a significant interaction effect of time and hardiness. The high hardiness group experienced less insomnia symptoms before and towards the end of the mission. Conclusions: The results indicate that high levels of hardiness may be a protective factor between the stressors of a naval mission and symptoms of insomnia.

Does psychological capital moderate the relationship between worries about accidents and sleepiness?

The present study investigated psychological capital (PsyCap) as a protective factor in the relationship between worries about accidents and sleepiness among seafarers. The hypothesis that strong PsyCap weakens the relationship between worries about accidents and sleepiness was tested in a cross-sectional sample of 397 maritime workers. In contrast to expectations, the findings indicated a reverse buffering effect in that PsyCap only had a protective impact on sleepiness when worries about accidents were low. For workers that were highly worried, a strong PsyCap was associated with increased levels of sleepiness. The established associations remained consistent after controlling for workers’ years of experience as seafarers, and their ratings of psychological safety climate. An interpretation of this finding is that seafarers with high levels of PsyCap will be attentive when the threat level is serious, but will not be bothered when exposed to everyday strain and hassles associated with their work situation

Paths to positive growth in parents bereaved by drug-related death: A mixed-method study

Introduction: Drug-related deaths (DRDs) are a major public health challenge. Losing a child to a DRD can be a very stressful life event, which places parents at risk of mental and physical health problems. However, traumatic experiences like losing a child to DRD can paradoxically also lead to positive psychological changes. A mixed-method approach was used to understand the complexity of the phenomenon of post-traumatic growth experienced by parents following a DRD. Method: By combining data from a survey (n = 89) and interviews (n = 14), we explored positive growth experiences among Norwegian parents. We conducted descriptive analyses of the sample’s demographic characteristics and mean scores for Post-traumatic Growth Inventory (PTGI-SF) items. Hierarchical multiple regression was used to examine the influence of the ability to perform daily activities (WSAS), self-efficacy (GSE-SF), social support (CSS), and symptoms of prolonged grief (PG-13) on the outcome variable of post-traumatic growth (PTGI-SF). Reflexive thematic analysis was applied to analyze the qualitative data. Finally, we integrated the results of the survey and the interviews. Results: For items measuring post-traumatic growth, parents scored highest on the item “I discovered that I’m stronger than I thought I was” and lowest on the item “I am able to do better things with my life.” Self-efficacy and social support had a statistically significant relation with post-traumatic growth. Two themes were generated from the interviews: (I) new perspectives on life and (II) new paths in life. Even though the “New Possibilities” subscale had the lowest mean score for the PTGI-SF, new paths in life were important for many of the interviewed parents. Discussion: Parents described traumatic stressors associated with having a child who uses narcotics and hence experienced positive changes even before losing their child. We argue that on an individual level, the consequences of spillover stigma, low self-efficacy, and intrusive rumination can hinder potential post-traumatic growth. On a group level, enhancing network support may increase post-traumatic growth experiences. Hence, parents who have experienced a DRD can benefit from help to activate their social networks and strengthen their self-efficacy.publishedVersio

Psychopathy, anxiety, and resiliency – Psychological hardiness as a mediator of the psychopathy–anxiety relationship in a prison setting

The literature on the association between psychopathy and anxiety is somewhat mixed, but it has been proposed that one possible advantage of psychopathy might be resiliency against anxiety. Another construct related to resiliency is psychological hardiness, and several studies have identified associations between psychological hardiness, anxiety responses, and physical and mental health effects of stress. The aim of the current study is to examine whether characteristics of psychological hardiness mediate the relationship between traits of psychopathy and experienced anxiety in a prison setting. The results showed a divergence in the psychopathy construct, since two underlying factors (the two-factor model of the PCL-R) had divergent relationships with anxiety. Through mediation analyses (PROCESS), we found this relationship to be partly mediated by the commitment dimension of psychological hardiness. To the best of our knowledge, this is the first study to explore the possible mediating effect of psychological hardiness on the relationship between psychopathy and anxiety. The relative immunity to anxiety previously linked to psychopathy could thus be partly explained by higher levels of hardiness commitment.publishedVersio

Concentrated transdiagnostic and cross-disciplinary group treatment for patients with depression and with anxiety: a pilot study

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.publishedVersio
