Prognostic subgroups of chronic pain patients using latent variable mixture modeling within a supervised machine learning framework.

The present study combined a supervised machine learning framework with an unsupervised method, finite mixture modeling, to identify prognostically meaningful subgroups of diverse chronic pain patients undergoing interdisciplinary treatment. Questionnaire data collected at pre-treatment and 1-year follow up from 11,995 patients from the Swedish Quality Registry for Pain Rehabilitation were used. Indicators measuring pain characteristics, psychological aspects, and social functioning and general health status were used to form subgroups, and pain interference at follow-up was used for the selection and the performance evaluation of models.

Interdisciplinary pain rehabilitation for patients with Ehlers-Danlos syndrome and hypermobility spectrum disorders.

Objective: Chronic pain is a common manifestation of Ehlers-Danlos syndrome and hypermobility spectrum disorders; thus it is often suggested that patients undergo generic interdisciplinary pain rehabilitation, despite there being little evidence to support this decision. The aim of this study is to examine the effectiveness of standard rehabilitation programmes for chronic pain on patients with Ehlers-Danlos syndrome and hypermobility spectrum disorders, compared with patients with other chronic pain disorders.

Subjects: Data, collected between 2008 and 2016, were extracted from a Swedish national registry.

Work Interventions Within Interdisciplinary Pain Rehabilitation Programs (IPRP) - Frequency, Patient Characteristics, and Association with Self-Rated Work Ability.

Background: Interdisciplinary pain rehabilitation programs (IPRPs) help people with chronic pain improve their health and manage their work; however, the way IPRPs address sick leave could be improved. Although work interventions can be a part of IPRP, it is not well known how and to what extent.

Aim: This study explores the frequency of work interventions and the characteristics of patients who participate in work interventions as part of IPRP at specialist pain rehabilitation departments in Sweden.

Fear network and pain extent: Interplays among psychological constructs related to the fear-avoidance model.

Objective: Psychological constructs related to the fear-avoidance model such as fear of movement, pain catastrophizing, and affective distress have been found to be inter-related among patients with chronic pain. However, relationships of these constructs have mostly been examined using regression-based analyses. This cross-sectional study employs a novel analytical approach, network analysis, to illustrate the complex interplays among these variables as well as pain intensity and pain interference.

Psychological Acceptance in Adults With Hearing Loss-Psychometric Evaluation and Validation of the Hearing Acceptance Questionnaire.

Objectives: Hearing loss is common and a major contributor to the global number of years lived with disability. An increasing number of studies have begun to consider the specific psychological processes by which distressing thoughts, emotional experiences and non-adaptive behaviours exert an influence on functioning and health among those who suffer from audiological disorders. Psychological acceptance has recently been proposed to be a core process but has to date not been systematically examined among individuals with hearing problems.

Ehlers-Danlos Syndrome and Hypermobility Syndrome Compared with Other Common Chronic Pain Diagnoses-A Study from the Swedish Quality Registry for Pain Rehabilitation.

Although chronic pain is common in patients with Ehlers-Danlos syndrome (EDS) and hypermobility syndromes (HMS), little is known about the clinical characteristics of these groups. The main aim was to compare EDS/HMS with common local and generalized pain conditions with respect to Patient Reported Outcome Measures (PROMs). Data from the Swedish Quality Register for Chronic Pain (SQRP) from 2007 to 2016 ( = 40,518) were used, including patients with EDS/HMS ( = 795), fibromyalgia ( = 5791), spinal pain ( = 6693), and whiplash associated disorders (WAD) ( = 1229).

Patients selected to participate in multimodal pain rehabilitation programmes in primary care-a multivariate cross-sectional study focusing on gender and sick leave.

Background and aims A multimodal rehabilitation programme (MMRP) is an evidence-based treatment of chronic pain conditions. The complexity involved in chronic pain needs to be identified and evaluated in order to adapt the rehabilitation to patients' needs. The aim was to investigate the multivariate relationships between self-reported variables in patients with chronic pain before taking part in MMRP in primary care, with a special focus on gender and degree of sick leave.

Long-term outcomes of multimodal rehabilitation in primary care for patients with chronic pain.

Objectives: To investigate the outcomes 1 year after multimodal rehabilitation programmes in primary care for patients with chronic pain, both as a whole and for men and women separately. A second aim was to identify predictive factors for not being on sickness absence at follow-up after 1 year.

Methods: A prospective longitudinal cohort study of 234 patients, 34 men and 200 women, age range 18-65 years, who participated in multimodal rehabilitation programmes in primary care in 2 Swedish county councils.

The role of pain in chronic pain patients' perception of health-related quality of life: a cross-sectional SQRP study of 40,000 patients.

Background and aims Health-related quality of life (Hr-QoL) reflects the burden of a condition on an overarching level. Pain intensity, disability and other factors influence how patients with chronic pain perceive their condition, e.g.

Internet-based acceptance and commitment therapy for psychological distress experienced by people with hearing problems: a pilot randomized controlled trial.

Psychological distress is common among people with hearing problems, but treatments that specifically target this aspect have been almost non-existent. In this pilot randomized controlled trial, an eight-week long Internet-based treatment, informed by Acceptance and Commitment Therapy, was administered to explore the feasibility and efficacy of such a treatment. Included participants were randomized to either treatment (n = 31) or wait-list control (n = 30) condition.

Do pain characteristics guide selection for multimodal pain rehabilitation?

Objective: To determine whether self-reported pain measures are associated with selection for multimodal or multidisciplinary rehabilitation (MMR) and whether this selection is influenced by sex.

Design: Cross-sectional cohort study.

Subjects: A total of 1,226 women and 464 men with chronic pain conditions from 2 university hospitals.

Weak outcome predictors of multimodal rehabilitation at one-year follow-up in patients with chronic pain-a practice based evidence study from two SQRP centres.

Background: For patients with chronic pain, the heterogeneity of clinical presentations makes it difficult to identify patients who would benefit from multimodal rehabilitation programs (MMRP). Yet, there is limited knowledge regarding the predictors of MMRP's outcomes. This study identifies predictors of outcome of MMRPs at a 12-month follow-up (FU-12) based on data from the Swedish Quality Registry for Pain Rehabilitation (SQRP).

Differences in alexithymia and emotional awareness in exhaustion syndrome and chronic fatigue syndrome.

Symptoms of Exhaustion Syndrome (ES) and Chronic Fatigue Syndrome (CFS) are overlapping and create difficulties of differential diagnosis. Empirical studies comparing ES and CFS are scarce. This study aims to investigate if there are any emotional differences between ES and CFS.

Internet-Based Acceptance and Commitment Therapy for Psychological Distress Experienced by People With Hearing Problems: Study Protocol for a Randomized Controlled Trial.

Purpose: Psychological distress and psychiatric symptoms are prevalent among people with hearing loss or other audiological conditions, but psychological interventions for these groups are rare. This article describes the study protocol for a randomized controlled trial for evaluating the effect of a psychological treatment delivered over the Internet for individuals with hearing problems and concurrent psychological distress.

Method: Participants who are significantly distressed will be randomized to either an 8-week Internet-delivered acceptance-based cognitive behavioral therapy (i.

Bridging the Gap Between Hearing Screening and Successful Rehabilitation: Research Protocol of a Randomized Controlled Trial of Motivational Interviewing via Internet.

Purpose: Studies point to low help-seeking after a failed hearing screening. This research forum article presents the research protocol for a randomized controlled trial of motivational interviewing via the Internet to promote help-seeking in people who have failed an online hearing screening.

Method: Adults who fail a Swedish online hearing screening, including a speech-in-noise recognition test, will be randomized to either an intervention group (participating in motivational interviewing) or an active control group (reading a book on history of hearing aids).

Predicting Speech-in-Noise Recognition From Performance on the Trail Making Test: Results From a Large-Scale Internet Study.

Objective: The aim of the study was to investigate the utility of an internet-based version of the trail making test (TMT) to predict performance on a speech-in-noise perception task.

Design: Data were taken from a sample of 1509 listeners between ages 18 and 91 years old. Participants completed computerized versions of the TMT and an adaptive speech-in-noise recognition test.

The acceptance of hearing disability among adults experiencing hearing difficulties: a cross-sectional study.

Objective: This study developed the Hearing Disability Acceptance Questionnaire (HDAQ) and tested its construct and concurrent validities.

Design: Cross-sectional.

Participants: A total of 90 participants who were experiencing hearing difficulties were recruited in the UK.

Internet-based hearing screening using speech-in-noise: validation and comparisons of self-reported hearing problems, quality of life and phonological representation.

Objectives: For the last decade a host of different projects have been launched to allow persons who are concerned about their hearing status to quickly and at a low cost test their hearing ability. Most often, this is carried out without collecting complementary information that could be correlated with hearing impairment. In this two-part study we first, present the development and validation of a novel Internet-based hearing test, and second, report on the associations between this test and phonological representation, quality of life and self-reported hearing difficulties.

Costs of suppressing emotional sound and countereffects of a mindfulness induction: an experimental analog of tinnitus impact.

Tinnitus is the experience of sounds without an appropriate external auditory source. These auditory sensations are intertwined with emotional and attentional processing. Drawing on theories of mental control, we predicted that suppressing an affectively negative sound mimicking the psychoacoustic features of tinnitus would result in decreased persistence in a mentally challenging task (mental arithmetic) that required participants to ignore the same sound, but that receiving a mindfulness exercise would reduce this effect.
