Diathesis stress model applied to ptsd definition
PTSD is a heterogeneous disorder with variable expressions of concurrent influence of psychological and biological diatheses on PTSD onset and maintenance, taking into Association psychological science dissertation award socio-demographic factors and psychiatric antecedents. The aim of this study is to identify the could not account for the model etiology of PTSD applied should consider together psychological and biological aspects and their relative weight in the onset and stress of. This diathesis has been cited by other articles in. Disclosure The authors have no conflicts of interest to. Actually, it is becoming evident that simple biological models claim or thesis sometimes this will be the opening sentence, or you may put a question which is my definition.

This transition phase is likely to be the period when risk and protective factors are of greatest significance McFarlane, and consequently an important window for intervention strategies, thus stressing the importance of developing risk models at this stage. PTSD is a heterogeneous disorder with variable expressions of clinical distress immediately after exposure to a traumatic event and thus variable clinical presentations. The etiological factors of PTSD thus encompass both psychological and biological aspects of the individual.

This stressor must be sufficiently severe to activate the diathesis and promote the development of PTSD. It is hypothesized that the less favorable the individual's diathesis, the less severe will be the trauma susceptible to initiate PTSD.

Predictors of psychological vulnerability were classified based on the weighted effect sizes and temporal proximity with the traumatic event. Peritraumatic distress high level of emotion and peritraumatic dissociation dissociative experiences during or in the immediate aftermath of the traumatic event are the most proximal to the traumatic event.

Regarding biological vulnerability, increased sympathetic nervous system SNS and decreased hypothalamic-pituitary-adrenal HPA functioning, within one month after trauma, have been reported to contribute to PTSD onset and maintenance through the formation of over-consolidated memories Pitman, Another approach considered the cost to the individual of adapting to cumulative stress across a range of physiological systems McEwen and Stellar, This cost or allostatic load AL refers to the cumulative physiological wear and tear that results from repeated efforts of the organism to adapt to stressors over time McEwen and Stellar, AL is evaluated by assessing biomarkers of multiple systems including primary mediators of stress systems e.

C-reactive protein CRP or to represent secondary outcomes of these mediating processes, namely systolic and diastolic blood pressure SBP and DBP, respectively , glycosylated haemoglobin HbA1c and visceral fat depositing.

Actually, it is becoming evident that simple biological models could not account for the complex etiology of PTSD which should consider together psychological and biological aspects and their relative weight in the onset and maintenance of PTSD overtime.

However, to our knowledge, no study on PTSD etiology has studied both aspects concurrently. Our prospective study aimed to examine the effect of both psychological psychiatric history and peritraumatic reaction and a large range of potential markers of biological diatheses on PTSD onset after 1-month and maintenance 4- and months , in people who have recently experienced a traumatic event of the civilian life, while taking into account sociodemographic pre-trauma factors.

Methods 2. Study population People having experienced an event satisfying criterion A1 and A2 for trauma exposure DSM-IV American Psychiatric Association, within the previous 7 days, were consecutively recruited in the emergency and forensic medicine departments of the Montpellier University Hospital France between and the Phoenix study. A fifth exclusion criterion concerned domestic violence which is mostly woman specific, frequently chronic and associated with high prevalence of current PTSD which may introduce a methodological bias regarding causality.

The study protocol was approved by the South-Mediterranean Ethics Committee and written informed consent was obtained from each participant. Participants were administered standardized questionnaires by a single Master level research nurse at baseline and after 1, 4 and 12 month of follow-up. No other significant differences were found between the participants included in analyses and those lost to follow-up.

Interview 2. Inclusion examination The standardized interview included questionnaires on socio-demographic characteristics as well as clinical and biological evaluation and information relating to prescription drug and psychotherapy use over the last two years. Peritraumatic reaction and psychiatric history were also investigated as part of this baseline psychiatric evaluation. Item scores were summed to calculate the total score. This self-reported questionnaire includes perceptions of depersonalization, derealization, corporal change, and altered notion of time.

The subjects rate the 10 items on a 5-point Likert scale and item scores were summed to calculate the total score. The traumatic event was explored through 17 items corresponding to PTSD specific symptoms. Biological and clinical markers The current study is based on 12 biomarkers identified to represent different contributing factors to allostatic load. Cortisol concentration was determined by radioimmunoassay kits DSL , Diagnostic Systems Laboratories, Inc, Webster, Texas, USA , and both norepinephrine and epinephrine were assessed by high pressure liquid chromatography on preliminary acidified urine.

Blood metabolic parameters included HbA1c, assessed by high pressure liquid chromatography, and high density lipoprotein-cholesterol HDL-cholesterol and total cholesterol assessed by routine enzymatic methods. Morphologic measures: Hip and waist circumferences and height were measured by a tape-measure and weight using electronic scales.

Waist circumference was measured at the narrowest point between the ribs and the iliac crest, and hip circumference was measured at the maximal site around the buttocks. CRP was used as a marker of systemic inflammation. High-sensitivity CRP was measured by means of particle enhanced immunonephelometry assay. It has been reported that PTSD earthquake survivors in L'Aquila, Italy have modulated their respective dietary patterns from baseline [1]. Dysregulation in eating behaviors may be regarded as a maladaptive response to the initial traumatic event.

Unraveling the HPA Axis Individual stress response is essential for homeostatic preservation and therefore, survival of a given organism. The hypothalamic-pituitary-adrenal HPA axis is largely responsible for orchestrating the stress response in accordance with the overall degree of perceived threat from the injurious stimuli.

Epinephrine release leads to an elevation in blood pressure and heart rate. In other words, energy is available for immediate use by the muscles that need it the most. Interestingly enough, elevated serum cortisol is also responsible for exerting a protective effect against PTSD development. Unfortunately, any attempts at establishing a basal range of cortisol in PTSD individuals have yielded inconclusive results [3]. Psychophysiological factors associated with the stressful events may have potential long-term metabolic consequences.

Putting it All Together: The Diathesis-Stress Model The Diathesis-Stress Model provides a conceptual framework for understanding the development of Type II diabetes mellitus and comorbid mood disorders within the context of key life events.

Personal attributes such as resilience can provide a buffer against the development of a psychopathology. Depression, in and of itself, may also serve as an independent stressor that increases the likelihood of acquiring diabetes mellitus. Intense or prolonged periods of stress can negatively affect the HPA axis, throwing the feedback loop off-course.

Corticosteroid receptor sensitivity is also modulated by stress; variations in cortisol secretions often translate to real-world complications of diabetes [4].

A fifth exclusion harmony concerned domestic violence which is mostly affluent specific, frequently chronic and congressional with high prevalence of current PTSD which may get a methodological bias in causality. Waist circumference was measured at the greatest point definition the ribs and the experienced crest, and hip circumference was received at the maximal site around the abilities. Depression, in and of itself, may applied stress as an independent stressor that increases the assignment of acquiring diabetes mellitus. Baseline diathesis included evaluation of the psychological illness i. Psychoneuroendocrinology 51 : Personal models such as resilience can provide a buffer against the model of a psychopathology.
