    Examining the impact of personality and situational factors on decision making among military staffs2014In: Journal of Military Studies, ISSN 1799-3350, Vol. 5, no 2Article in journal (Refereed)
    Abstract [en]

    Military staff performance may be inferior due to several reasons. The purpose of the present survey was to study the impact of stress reactions, personality factors, situation awareness, and maladaptive group dynamics on the quality of the decision-making in Swedish high-level military staffs. Participants were mainly captains and majors, but also lieutenant colonels and colonels took part (n = 256, 61 % response rate). A mainly self-made questionnaire was administered in two staff exercises. Maladaptive group dynamics, stress exposure, lack of situation awareness, and negative stress reactions were the strongest predictors of poor staff performance, while personality had less impact.

    Reactions and Performance of Swedish Peacekeepers in Life-Threatening Situations2002In: International Peacekeeping, ISSN 1353-3312, E-ISSN 1743-906X, Vol. 9, no 1, p. 133-152Article in journal (Refereed)
    Abstract [en]

    This study maps reactions activated in peacekeeping personnel by life-threatening situations and explores how these reactions affect psychological functioning. In-depth interviews were carried out with 30 informants from the Swedish peacekeeping force serving in Bosnia between 1993 and 1995. All participants had experienced shooting incidents or other highly threatening events. Two models were formed. A descriptive model structures the content of the interviews according to the phase and type of situation from which they were mainly reported, as well as whether they were mainly reported by officers or privates. A theoretical model forms the basis for a discussion about the individual and situational factors that affect the specific reactions and how their interaction with role expectations affects performance. The informants were generally satisfied with their performance. Two factors associated with lower performance were either that the life-threatening situation implied loss of control or it demanded complex cognitive activity.

    Military observers' reactions and performance when facing danger2004In: Military Psychology, ISSN 0899-5605, E-ISSN 1532-7876, Vol. 16, no 4, p. 211-229Article in journal (Refereed)
    Abstract [en]

    Some groups have to face threats and dangers professionally with maintained cognitive functioning, which implies a need to know both the extent to which maladaptive reactions occur and the factors that may affect it. This study examines self-reported reactions and performance when facing risks and dangers on peacekeeping observer missions. The sample consisted of 154 military observers. A self-made questionnaire, including the General Health Questionnaire and the Sense of Coherence (SOC) scale, was used. We found that feelings of invulnerability were common in relation to mission risks. In a specific danger incident, most participants subjectively performed well, although partial loss of cognitive functioning was reported in half of the cases and severely dysfunctional reactions in about one tenth. Cluster analysis showed that self-reported cognitive limitations in danger incidents were related to 2 factors: complicating situational factors, such as high levels of threat, complex decision demands, and minor control possibilities; and individual vulnerability factors, such as general worry and anger, low SOC, anxiety, and psychosomatic symptoms.
