From the Bio-Psycho-Social Model to the Development of a Clinical-Forensic Assessment Tool for Chronic Pain in Victims of Violence: A Research Protocol.

Violence against women impacts a minimum of 35% of the global female population, encompassing sexual, physical, and psychological forms. Perpetrators of this violence include partners, family members, or strangers. Its ramifications are substantial, evident in the prevalence of chronic pain reported by between 48% and 84% of women who have experienced abuse, with an odds ratio of 2.08. Notably associated diagnoses include pelvic/vaginal pain, fibromyalgia, irritable bowel syndrome/bowel symptoms, abdominal pain, migraine/headache, and back and neck pain. These diagnoses significantly limit a woman's ability to participate in daily activities, such as exercising or working, leading to genuine disability. Despite substantial evidence, the precise cause and etiology of these conditions remain unclear. Adhering to the bio-psycho-social model, it is conceivable that chronic pain in victims of violence cannot be attributed to a single factor alone, but rather to a combination of all three: biological, psychological, and social factors. Uncovering these factors could have significant clinical and legal implications. On one hand, it would be possible to conduct screenings to avoid developing chronic pain. and guide individuals toward the correct treatment. On the other hand, victims could seek compensation for chronic pain resulting from violence. Considering the limited knowledge about the causes of chronic pain and the absence of tools to identify risk factors or a set of tests for evaluating victims of violence, the goal of the research described in this project protocol is to pinpoint the specific contributing factors for chronic pain due to violence victimization. Additionally, it aims to devise a comprehensive protocol for assessing these factors in forensic science.

The association between violence against women and chronic pain: a systematic review and meta-analysis.

Violence against women is a phenomenon that involves at least 35% of women worldwide. Violence can be sexual, physical, and/or psychological, perpetrated by the partner, another family member, or a stranger. Violence is a public health problem because its consequences include higher morbidity, higher mortality, and short and long-term physical and psychological health diseases. Most studies prove an association between any type of violence and some chronic pain diagnoses but no one has done a complete collection of this evidence. This systematic review and meta-analysis aimed to evaluate whether this association is statistically significant, including the largest number of studies. Through the inclusion of 37 articles, the association has been demonstrated. Compared with no history of violence, women who did experience violence showed 2 times greater odds of developing chronic pain. The impact of violence was significant also on fibromyalgia separately, but not on pelvic pain.PROSPERO registrationPROSPERO CRD42023425477.

Urban safety and psychological distress during the pandemic: the results of a longitudinal study.

Introduction: In the last decades, a large body of literature has explored the topic of perceived safety and fear of crime in urban environments. The effects of psychological factors on such feelings have been studied, but rarely using prospective studies, and never when these factors intercept a worldwide dramatic event like the pandemic. This research aimed to analyze the variations of the feelings of urban safety during the pandemic, the role of resiliency and the effect of psychological stressors such as anxiety, stress, and depression. Methods: During 2019 and 2022, before and after the pandemic, a face-to-face interview was administered to the same group of 195 participants. The PUSAS scale was used to measure unsafety, the ER89-R to assess for resiliency, the DASS-21 to collect data about the general distress (anxiety, stress and depression), and the CAS scale was used to evaluate the specific coronavirus anxiety. Structural equation models were applied to test a theoretical framework grounded on the relationships between these measures. Results: The research findings showed decreased feelings of unsafety across the pandemic, consistent with the literature. The positive effect of ego-resiliency was significant but only for its interaction with data collected before the pandemic, whilst stress and anxiety impacted unsafety in 2022 through different pathways. None of the symptoms of general distress influenced the concern about crime and sense of vulnerability, as the feelings of unsafety were found independent from the variations of the specific coronavirus anxiety. Discussion: Although the research findings did not confirm the impact of coronavirus, they presented some facets that disconfirm what the literature reported about the relationships between psychological distress and fear of crime. Implications about measurement issues are discussed.

The Risk Factors of Chronic Pain in Victims of Violence: A Scoping Review.

Violent situations are unfortunately very frequent in women and children all over the world. These experiences have long-term consequences for adult physical and psychological health. One of the most reported is chronic pain, defined in various sub-diagnoses and present in all types of violence. Unfortunately, the etiology of this condition is not clear and neither are the predisposing factors. The aim of this scoping review is to examine the literature trends about the probable risk factors of chronic pain in violence victims. Considering a bio-psycho-social model, it is possible to hypothesize the presence of all these aspects. The results will be discussed in the present article.

Linear and non linear measures of pupil size as a function of hypnotizability.

Higher arousal and cortical excitability have been observed in high hypnotizable individuals (highs) with respect to low hypnotizables (lows), which may be due to differences in the activation of ascending activating systems. The present study investigated the possible hypnotizability-related difference in the cortical noradrenergic tone sustained by the activity of the Locus Coeruleus which is strongly related to pupil size. This was measured during relaxation in three groups of participants-highs (N = 15), lows (N = 15) and medium hypnotizable individuals (mediums, N = 11)-in the time and frequency domains and through the Recurrence Quantification Analysis. ECG and Skin Conductace (SC) were monitored to extract autonomic indices of relaxation (heart interbeats intervals, parasympathetic component of heart rate variability (RMSSD) and tonic SC (MeanTonicSC). Most variables indicated that participants relaxed throughout the session. Pupil features did not show significant differences between highs, mediums and lows, except for the spectral Band Median Frequency which was higher in mediums than in lows and highs at the beginning, but not at the end of the session.Thus, the present findings of pupil size cannot account for the differences in arousal and motor cortex excitability observed between highs and lows in resting conditions.
