Symptom attribution and treatment seeking in Australian veterans.

To understand the role of symptom attribution in treatment-seeking behaviours, survey results of 1356 veterans (age = 38-72 years) were analysed. Controlling for symptom frequency, significant relationships were found for specialist and psychological-related consultations. Those who favoured psychological explanations for symptoms were more likely to attend specialist and psychology-related consultations and filled significantly more prescriptions than people who predominantly explained symptoms by situational factors (normalisers). Veterans who favoured somatic explanations attended more general practitioner consultations than normalisers. Attributional style should be considered part of the constellation of factors influencing healthcare usage. Normalisers, the predominant group, used fewest health services and filled fewest prescriptions; this may have important implications for healthcare considering their tendency to minimise or downplay symptoms.

Understanding the biosecurity monitoring and reporting intentions of livestock producers: Identifying opportunities for behaviour change.

In many countries, government strategies for biosecurity planning and outbreaks depend upon private livestock producers being willing and able to conduct surveillance of their animals and the timely reporting of suspicious signs of disease. From a behavioural perspective, these two kinds of behaviours - surveillance and reporting - should be treated separately when developing a biosecurity plan in which producers play a key role in the prevention, detection, and reporting of animal diseases. Having an effective surveillance system in place is conceptually and practically independent of a reporting system that is both feasible and trustworthy. The behavioural intentions of 200 Australian producers to monitor their livestock and report to either the government or a private vet were measured in a structured telephone interview. Structural equation modelling revealed that these intentions had different statistical relationships with a common set of predictor variables. Moreover, classification of the producers based on belief about monitoring and surveillance resulted in three contrasting groups. These results are discussed in terms of their meaning for the development of behavioural strategies to promote surveillance and monitoring of animal disease.

Symptom attribution and symptom reporting in Australian Gulf War veterans.

OBJECTIVE: To better understand the consistent elevated symptom reporting by Gulf War veterans; we compared Australian Gulf War veterans and military-comparison group on symptom attributional styles and the relationship with total number and grouping of somatic and psychological symptoms. METHOD: Postal questionnaires were completed by Australian Gulf War veterans (n=697) and military-comparison group (n=659) in 2000-2002 and 2011-2012. Data were collected on deployments, military-psychological stressors, symptom reporting, symptom factors and attributional style (normalising, psychologising, somatising, mixed-attribution). RESULTS: Gulf War veterans did not differ in attributional style from comparison group (p>0.05); normalising was the predominant style. Groups were combined for analyses. Psychologisers reported the highest overall symptoms (mean(M)=10.95, standard deviation(SD)=9.15), the most psychophysiological (M=1.71, SD=2.82), cognitive (M=5.79, SD=5.09) and arthro-neuromuscular symptoms (M=1.53, SD=1.73). Psychologisers and somatisers reported significantly more symptoms across overall symptoms, all three symptom factors and psychological distress than normalisers. Normalisers consistently reported fewest overall symptoms (M=2.85, SD=4.49), psychophysiological (M=0.40, SD=0.98), cognitive (M=1.14, SD=2.22), and arthro-neuromuscular symptoms (M=0.72, SD=1.31). Persistent symptoms, rather than remitted, between baseline and follow-up were associated with increased rates of psychologising and mixed-attribution compared with normalising. For incident symptoms a similar pattern was observed, some symptoms also showed increased rates of somatising. CONCLUSIONS: In veterans, psychologising was associated with higher symptom reporting, whilst somatisers and mixed-attribution also demonstrated higher reporting than normalisers. Symptom persistence and incidence were associated with symptom attribution. The findings indicate that attributional style is associated with patterns of symptom reporting and highlights both past and present symptoms may influence attributional style.

Support mechanisms and vulnerabilities in relation to PTSD in veterans of the Gulf War, Iraq War, and Afghanistan deployments: a systematic review.

Pretrauma factors of psychiatric history and neuroticism have been important in highlighting vulnerability to posttraumatic stress disorder (PTSD), whereas posttrauma support mechanisms have been associated with positive health and well-being outcomes, particularly in veterans. The relationship between these factors and PTSD has not been the subject of a systematic review in veterans. An online search was conducted, supplemented by reference list and author searches. Two investigators systematically and independently examined eligible studies. From an initial search result of 2,864, 17 met inclusion criteria. A meta-analysis of unit cohesion involving 6 studies found that low unit cohesion was associated with PTSD, standardised mean difference of -1.62, 95% confidence interval (CI) [-2.80, -0.45]. A meta-analysis of social support involving 7 studies found that low social support was associated with PTSD, standardised mean difference of - 12.40, 95% CI [-3.42, -1.38]. Three of 5 studies found a significant relationship between low-family support and PTSD; insufficient data precluded a meta-analysis. Regarding pretrauma vulnerability, 2 studies on psychiatric history and 1 on neuroticism found positive relationships with PTSD. Posttrauma factors of low support were associated with higher reporting of PTSD. Cross-sectional methodology may be inadequate to capture complex relationships between support and PTSD; more longitudinal research is required.
