Effects of Direct and Indirect Suggestions for Analgesia: The Role of Hypnotizability and Expectation of Pain Relief.

Among the methods for cognitive control of pain, the suggestions for analgesia-direct or indirect-have been widely and successfully used in experimental and clinical trials. The primary aim of this study was to contribute to the debate about the difference in the effectiveness of indirect and direct suggestions for the management of experimental pain in the ordinary state of consciousness. The secondary aim of the study was to ascertain the role of hypnotizability and expectation of pain relief in the suggestions' effect.

Role of history of traumatic life experiences in current psychosomatic manifestations.

Objectives: Although the relationship between traumatic experiences (TEs) and psychosomatic manifestations (pain, somatization, somatosensory amplification [SSA], and alexithymia) has been widely described, very few studies have investigated how these variables correlate with each other and with a history of TEs. The aim of this study was to investigate whether and how current psychosomatic manifestations are correlated with major and minor adult- and childhood TEs.

Methods: One hundred and forty-six patients (91 with pain) from the Pisa Gift Institute for Integrative Medicine Psychosomatics Lab.

Role of Personality and Psychiatric Disorders in the Perception of Pain.

Although previous studies have shown that psychiatric and personality disorders are more prevalent in chronic pain than in pain-free groups, few studies have investigated the prevalence of personality disorders (PerDs) in patients with chronic pain with and without a psychiatric comorbidity. The aim of the present study was therefore designed to investigate the burden of PerDs on the prevalence and perception of chronic pain in patients with and without psychiatric comorbidity. 232 patients from the Gift Institute for Integrative Medicine in Pisa, Italy, of which n = 161 (69.

Hypnotic analgesia in chronic pain: role of psychopathology and alexithymia.

Although the belief that hypnotizability is a mental dysfunction has been refuted over time, there is still research today that seeks to explore and clarify this preconception. The results of recent research indicate that, on the contrary, greater psychopathology is more frequent in subjects with low hypnotic susceptibility. Using the Stanford Hypnotic Susceptibility Scale type A (SHSS-A) for hypnotizability, Symptom Checklist-Revised (SCL-90-R) for psychopathology, and the Somatosensory Amplification Scale (SSAS) and Toronto Alexithymia Scale (TAS-20) for psychosomatic dimensions, we found no relationship between baseline psychopathology, alexithymia and hypnotizability in 69 subjects with chronic pain in this retrospective observational study.

Can interoceptive sensitivity provide information on the difference in the perceptual mechanisms of recurrent and chronic pain? Part I. A retrospective clinical study related to multidimensional pain assessment.

Objectives: Although neurobiological research has shown that interoception plays a role in the perception of pain and its chronification, the relationship between interoceptive sensitivity and pain has not been definitively confirmed by clinical studies. The aim of this study was therefore to better understand the relationship between interoceptive sensitivity, somatization, and clinical pain, and to identify any differences in the interoceptive sensitivity of patients with recurrent vs. chronic pain.

Mental, Physical and Socio-Economic Status of Adults Living in Spain during the Late Stages of the State of Emergency Caused by COVID-19.

Research has shown that the confinement measures implemented to curb the spread of COVID-19 can have negative effects on people's lives at multiple levels. The objective of this cross-sectional study was to better understand the mental, physical, and socio-economic status of adults living in Spain during the late stages of the state of emergency caused by COVID-19. Five hundred and forty-four individuals responded to an online survey between 3 June and 30 July 2020.

Placebo and hypnosis in the clinical setting: Contextual factors in hypnotic analgesia.

The assumption that hypnotic analgesia produces placebo effects is controversial. The cognitive dimension that can distinguish hypnosis from placebo analgesia has been suggested as hypnotic susceptibility. The aim of this study is to investigate the role of the relationship between patient and therapist, assumed to produce the placebo effect, in the clinical context of hypnotic treatment for pain.

Effects of COVID-19 Social Distancing Measures in Individuals with Chronic Pain Living in Spain in the Late Stages of the Lockdown.

Social distancing measures during the lockdown have had a negative impact on chronic pain patients' function. Research, however, has only focused on the early stages of the first lockdowns. The aim of this study was to improve the understanding of the effects of COVID-19 social distancing measures on individuals with chronic pain living in Spain during the late stages of the lockdown.

A retrospective observational study comparing somatosensory amplification in fibromyalgia, chronic pain, psychiatric disorders and healthy subjects.

Objectives: Somatosensory amplification (SA) has been described as an important feature of somatoform disorders, and an "amplifying somatic style" has been reported as a negative connotation of body perception. As widespread pain (WSP) in fibromyalgia (FM) is due to a central sensitization (CS) rather than organic alterations, there has been discussion as to whether FM is equivalent to or distinct from somatization disorder (SD). Assuming SD and FM are two distinct entities, an increase in somatic amplification should be expected only in subjects who have SD, regardless of the type of pain they experience.

Psychopharmacology of chronic pain.

Chronic pain is a frequent condition that affects an estimated 20% of people worldwide, accounting for 15%-20% of doctors' appointments (Treede et al., 2015). It lacks the acute warning function of physiologic nociception, and instead involves the activation of multiple neurophysiologic mechanisms in the somatosensory system, a complex neuronal network under the control of powerful autoregulatory loops and able to undergo rapid neuroplastic alteration (Verdu et al.

Relationship between Pain, Somatisation, and Emotional Awareness in Primary School Children.

Poor emotional awareness (EA) seems to play an important role in the aetiology of functional somatic complaints featuring pain as a form of somatisation. The aim of this study was to shed more light on this relationship by investigating the links between pain, somatisation, and emotional awareness in a nonclinical population of 445 children aged 6-10. Assessing pain through the Children's Somatisation Inventory (CSI), a very high percentage of the entire sample complained of experiencing pain at least one site (84.

The Influence of Trauma on Autobiographical Memory in the Assessment of Somatoform Disorders According to DSM IV Criteria.

Recalling an event impairs an individual's later ability to recall related knowledge. Impairment in this retrieval-induced forgetting (RIF) produces a dysfunction in autobiographical memory. This, like somatic symptoms, has been documented in trauma and sexual abuse survivors.

Pain modulation as a function of hypnotizability: Diffuse noxious inhibitory control induced by cold pressor test vs explicit suggestions of analgesia.

The aim of the present study was to compare the effects of explicit suggestions of analgesia and of the activation of the Diffuse Noxious Inhibitory Control (DNIC) by cold pressor test on pain perception and heart rate in healthy participants with high (highs, N=18), low (lows, N=18) and intermediate scores of hypnotizability (mediums, N=15) out of hypnosis. Pain reports and the stimulus-locked heart rate changes induced by electrical nociceptive stimulation of the left hand were studied in the absence of concomitant stimuli (Control), during suggestions of analgesia (SUGG, glove analgesia) and during cold pressor test used as a conditioning stimulus to the right hand (DNIC, water temperature=10-12°C) in the REAL session. Participants were submitted also to a SHAM session in which the DNIC water temperature was 30°C and the suggestions for analgesia were substituted with weather forecast information.

Chronic Low Back Pain: Perception and Coping With Pain in the Presence of Psychiatric Comorbidity.

This retrospective study investigated the influence of psychiatric comorbidity on pain perception and coping with pain in tertiary pain clinic patients, 427 treated for chronic low back pain (CLBP) and 629 for other forms of chronic pain (CG). No differences in psychosomatic dimensions were found between the two groups, but Italian Pain Questionnaire dimensions and intensity scores (t = 7.35; p < 0.
