Diagnostics, epidemiological observations and genomic subtyping in an outbreak of pullorum disease in non-commercial chickens.

Salmonella Gallinarum biovar Pullorum (S. Pullorum) is a poultry pathogen associated with significant economic losses and animal suffering. Strict eradication programmes have eliminated S. Pullorum from the commercial poultry sector in most regions, but occasional outbreaks still occur in the non-commercial population. In 2012, pullorum disease was diagnosed in a non-commercial flock in Sweden. Epidemiological, post-mortem and bacteriological investigations identified three more infected flocks. To study the epidemiological relationships between the flocks and evaluate different subtyping methods for S. Pullorum, 13 isolates from the four infected flocks were investigated by pulsed-field gel electrophoresis (PFGE) and multi-locus variable number tandem repeat analysis (MLVA). Four isolates collected from two non-commercial flocks in 2001 were also included. Six representative isolates from 2012 were further analysed by high-throughput sequencing. To differentiate between biovars Gallinarum and Pullorum, ten regions of difference (RODs) were investigated by in silico PCR. Three different PFGE-types were observed from the four epidemiologically linked farms in 2012 and MLVA further discriminated the isolates. SNP typing based on high-throughput sequencing clustered the four farms from the 2012 outbreak in two pairs. The PFGE, MLVA and high-throughput sequencing results suggested at least two different sources of infection or a common genetically mixed source in 2012. High-throughput sequencing is useful both for subtyping of S. Pullorum and may also be used for differentiating between the two biovars Pullorum and Gallinarum.

Cognitive behavioral therapy for frequent attenders in primary care.

AIM: The aim of the study is to investigate if cognitive behavioral therapy given in a group setting affects anxiety and depression, stress, pain, coping strategies during daily life, and health-related quality of life (HRQoL), among frequent attenders (FAs) in primary care. METHODS: Cognitive behavioral therapy was offered to 331 FAs between 18 and 65 years of age, of whom 89 accepted and 54 completed all steps in the protocol; patients were assigned to 1 of 3 groups: 0, 6, and 12-month waiting time. The therapy consisted of 12 sessions administered in group format. Outcome measures were Beck's Anxiety Inventory (BAI), Beck's Depression Inventory (BDI), Hospital Anxiety and Depression Scale (HADS), Everyday Life Stress (ELS), Coping Strategy Questionnaire, Multidimensional Pain Inventory-Swedish version, and Short Form-36. RESULTS: Mean age among patients who completed cognitive behavioral therapy was 49.9 years, with a female majority (79.6%). Anxiety and depression scores were reduced after treatment (BAI 16.7 vs 13.6; BDI 16.3 vs 15.7; HADS-Anxiety 8.41 vs 6.05; HADS-Depression 7.09 vs 5.69). Because waiting time itself did not affect symptoms, differences reflect treatment effects. Stress ratings were not affected by treatment. Use of nonadaptive coping strategies like praying and hoping and catastrophizing decreased. Frequent attenders experienced a higher sense of life control. Frequent attenders reported significantly lower HRQoL than general Swedish population norms in all 8 Short Form-36 domains including mental and physical component summary scores (MCS and PCS), and all domains were unaffected by treatment. CONCLUSION: Cognitive behavioral therapy exerts some beneficial effects in FAs. Content of treatment addressed musculoskeletal pain, stress, anxiety, and depression. This broad approach resulted in reduced anxiety, depression, and impact of pain because of enhanced life control.

Comparison of whole genome sequencing typing results and epidemiological contact information from outbreaks of Salmonella Dublin in Swedish cattle herds.

BACKGROUND: Whole genome sequencing (WGS) is becoming a routine tool for infectious disease outbreak investigations. The Swedish situation provides an excellent opportunity to test the usefulness of WGS for investigation of outbreaks with Salmonella Dublin (S. Dublin) as epidemiological investigations are always performed when Salmonella is detected in livestock production, and index isolates from all detected herds are stored and therefore available for analysis. This study was performed to evaluate WGS as a tool in forward and backward tracings from herds infected with S. Dublin. MATERIAL AND METHODS: In this study, 28 isolates from 26 cattle herds were analysed and the WGS results were compared with results from the epidemiological investigations, for example, information on contacts between herds. The isolates originated from herds in three different outbreaks separated geographically and to some extent also in time, and from the only region in Sweden where S. Dublin is endemic (Öland). RESULTS: The WGS results of isolates from the three non-endemic regions were reliably separated from each other and from the endemic isolates. Within the outbreaks, herds with known epidemiological contacts generally showed smaller differences between isolates as compared to when there were no known epidemiological contacts. CONCLUSION: The results indicate that WGS can provide valuable supplemental information in S. Dublin outbreak investigations. The resolution of the WGS was sufficient to distinguish isolates from the different outbreaks and provided additional information to the investigations within an outbreak.

Neurocognitive functioning and outcome of the Illness Management and Recovery Program for clients with schizophrenia and schizoaffective disorder.

The relationship between psychosocial programming and neurocognition has been established in previous research, but has not been explored in the context of the Illness Management and Recovery Program (IMR). This study examined associations between neurocognition and illness self-management skills acquisition, based on two previous trials of IMR. Neurocognitive functioning was assessed at baseline and post-treatment in 53 participants with schizophrenia or schizoaffective disorder who completed the IMR. Illness self-management was measured by the client and clinician versions of the Illness Management and Recovery Scale. Statistical analyses investigated improvements in neurocognitive functioning and possible association between illness self-management skills acquisition and neurocognitive functioning. Speed of processing as measured by the Trail Making Test A, was related to client-reported acquisition of illness self-management skills, before and after controlling for psychiatric symptoms and medication, but did not predict improvement in clinician ratings of client illness self-management skills. However, when controlling for client session attendance rates, the association between speed of processing and client-reported illness self-management skills acquisition ceased to be statistically significant, which suggests that compromised neurocognitive functioning does not reduce response to training in illness self-management in itself. The association between the frequency of attended IMR sessions and outcome of the IMR seems to decrease the negative impact of compromised neurocognition on illness self-management skills acquisition. Also, clients with slower speed of processing may experience less benefit from the IMR and may attend fewer sessions.

Changes in the risk management of Salmonella enterica subspecies diarizonae serovar 61:(k):1, 5, (7) in Swedish sheep herds and sheep meat due to the results of a prevalence study 2012.

BACKGROUND: The prevalence of Salmonella in food producing animals is very low in Sweden due to rigorous control programmes. However, no active surveillance is in place in sheep. The authorities decided to perform a prevalence study in sheep herds because findings at slaughter indicated that sheep associated S. diarizonae (S. enterica subspecies diarizonae serovar 61:(k):1, 5, (7)) might be common in sheep. Sampling was stratified by herd size in two groups, small herds with ≤ 30 animals and large herds with > 30 animals. In each stratum, 237 herds were selected at random. Faecal samples received from 244 out of the 474 randomly selected herds were analysed. RESULTS: A total of 40 of 100 (40%) of large herds and 17 of 144 (12%) of small herds were positive. The overall adjusted prevalence was 17.6% (95% CI, 12.9-22.2). Sheep associated S. diarizonae was detected in all counties (n = 21). Scientific opinions and an evaluation of on-farm control measures performed concluded that the impact of sheep associated S. diarizonae on human health is very low, and that risk management measures applied in response to findings of sheep associated S. diarizonae in sheep or sheep meat can be expected to have very little impact on reducing risks to human health. As a result, Swedish authorities decided to make an exemption for sheep associated Salmonella diarizonae in sheep and sheep meat in the current Salmonella control measures. CONCLUSIONS: Sheep associated S. diarizonae is endemic in Swedish sheep herds. It is more common in large herds and not limited to certain parts of the country. The responsible authorities concluded that current risk management actions regarding sheep associated S. diarizonae in sheep and sheep meat are not proportional to the risk. This is the first time in the history of the Swedish Salmonella control programme that an exemption from the legislation has been made for a specific serovar. If there is any future indication of an increasing risk, due to e.g. change in the pathogenicity or development of antimicrobial resistance, the risk assessment will be re-evaluated and control measures reinforced if needed.

Salmonella species in piglets and weaners from Uganda: prevalence, antimicrobial resistance and herd-level risk factors.

Non-typhoidal salmonellosis is of concern in humans in sub-Saharan Africa, and this is partly due to the high number of immunocompromised persons. Pork and pork products could be among the sources of these non-typhi Salmonella spp. The aim of this study was to identify Salmonella spp. in piglets and weaners in northern and eastern Uganda, characterize their antimicrobial resistance patterns and determine herd-level risk factors. Fecal samples were collected from 465 piglets and weaners from 93 herds (49 and 44 from northern and eastern Uganda, respectively). In addition, information about the herd management and potential risk factors were collected. The fecal samples were cultured for the identification of Salmonella spp. The Salmonella spp. confirmed by serotyping were further characterized by determination of minimum inhibitory concentration (MIC) to 12 antimicrobials by broth microdilution. At individual level, the total prevalence of Salmonella spp. was 12% (12.2% in northern and 11.9% in eastern Uganda). At herd level, the total prevalence was 39% (43% in northern and 34% in eastern Uganda). From 56 samples with Salmonella spp., 20 serovars were identified including two serovars identified only by their antigenic formulae. The predominant serovars were S. Zanzibar, S. Heidelberg, S. Infantis, S. Typhimurium, S. Stanleyville, S. Aberdeen and S. Kampala. In total, 57% of the 53 Salmonella spp. analyzed, originating from 27% of the herds, were resistant to at least one antimicrobial agent. The majority of drug-resistant isolates (60%) were from northern Uganda. Eight multidrug-resistant (MDR) isolates were from northern Uganda and three MDR isolates were from eastern Uganda. Increased prevalence of Salmonella spp. was associated with feeding the young and adults separately as compared to feeding the young and adults together (p=0.043, OR=4.3; 95% CI 1.1, 17.38). Protective factors were "intensive" method of keeping the pigs versus "tethering and roaming" (p=0.016, OR=0.11; 95% CI 0.02, 0.64), "intensive" method versus "semi-intensive" method (p=0.048, OR=0.12; 95% CI 0.01, 0.96) and cleaning feeders after every two days versus daily (p=0.017, OR=0.18; 95% CI 0.05, 0.72). This study has revealed a high prevalence of infection of piglets and weaners with diverse non-typhi Salmonella serovars and highlights the potential role of pork and pork products as sources of these organisms for humans. In addition, this study has identified protective factors that could be promoted to control Salmonella spp. and in antimicrobial resistance reduction programs in rural pigs from Uganda.

Salmonella isolated from individual reptiles and environmental samples from terraria in private households in Sweden.

BACKGROUND: This study investigates Salmonella spp. isolated from privately kept reptiles and from environmental samples such as bedding materials or water from the floor of the enclosures (terraria). It also compares isolation of Salmonella using Modified Semisolid Rappaport-Vassiliadis (MSRV) medium or selective enrichment in Rappaport-Vassiliadis-Soya (RVS) pepton broth. Cloacal swabs or swabs from the cloacal area were collected from 63 individual reptiles belonging to 14 households. All reptiles were from different terraria and from 62 of these, environmental samples were also collected. Sampling were done by the reptile owners according to written instructions and sent by mail immediately after sampling. All but three samples were analyzed within 24 h after collection. Colonies suspected for Salmonella were tested for agglutination and serotyped using the White-Kauffmann-Le Minor scheme. The relative sensitivity (se) and specificity (sp) for MSRV compared with RVS, and the agreement coefficient kappa (κ) were calculated. RESULTS: Salmonella was isolated from 50/63 (80%) terraria, either from the reptiles (31/63; 49%) or from bedding material (39/62; 63%). The most common subspecies was Salmonella enterica subspecies enterica followed by S. enterica subspecies diarizonae. In reptiles, the most common S. enterica subspecies enterica serovars were Java (n = 4) and Fluntern (n = 4), compared with the serovars Tennessee (n = 10) and Fluntern (n = 10) in the environmental samples. The exact same set of Salmonella subspecies and serovars were not isolated from the individual reptiles and the environmental samples from any of the households. Isolation using MSRV yielded more Salmonella isolates 61/113 (54%) than enrichment in RVS 57/125 (46%). The se was 97.9% (95% Confidence Interval 93.9-100), the sp 78.5% (95% CI 68.5-88.5) and the κ 0.74, indicating substantial agreement between the tests. CONCLUSIONS: Salmonella can be expected to be present in environments where reptiles are kept. This constitutes public health risks and should be considered during handling of the reptiles and during cleaning and disposal of bedding. A combination of different culturing techniques may be used to increase the isolation rate.

Can demographic and exposure characteristics predict levels of social support in survivors from a natural disaster?

OBJECTIVE: Lack of social support is a strong predictor for poor mental health after disasters. Psychosocial post-disaster interventions may benefit from targeting survivors at risk of low support, yet it is unknown whether demographic and disaster exposure characteristics are associated with social support. This study assessed if age, gender, educational status, cohabitation, and disaster exposure severity predicted aspects of informal social support in a cohort of Swedish survivors from the 2004 Southeast Asian tsunami. METHODS: The participants were 3,536 disaster survivors who responded to a mail survey 14 months after the disaster (49% response rate). Their perceptions of present emotional support, contact with others, tangible support, negative support and overall satisfaction with informal support were assessed with the Crisis Support Scale and analysed in five separate ordinal regressions. RESULTS: Demographic factors and exposure severity explained variation in social supports although the effect size and predictive efficiency were modest. Cohabitation and female gender were associated with both more positive and more negative support. Single-household men were at risk for low emotional support and younger women were more likely to perceive negative support. Higher education was associated with more positive support, whereas no clear pattern was found regarding age as a predictor. Disaster exposure severity was associated with more negative support and less overall support satisfaction. CONCLUSIONS: After a disaster that entailed little disruptions to the community the associations between demographic characteristics and social support concur with findings in the general population. The findings suggest that psychosocial disaster interventions may benefit from targeting specific groups of survivors.

Evaluation of the Illness Management and Recovery Scale in schizophrenia and schizoaffective disorder.

The aim of the present study was to evaluate the psychometric properties of the parallel client and clinician versions of the Illness Management and Recovery Scale (IMRS) developed to monitor the clients' progress in the Illness Management and Recovery (IMR) program in schizophrenia. A total of 107 study participants completed assessments of the IMRS, interview-based ratings of psychiatric symptoms, self-ratings of psychiatric symptoms, perception of recovery, and quality of life. Case managers completed the clinician version of the IMRS. Both versions of the scale demonstrated satisfactory internal reliability and strong test-retest reliability. The results also indicated convergent validity with interview-based ratings of psychiatric symptoms, self-rated symptoms, perception of recovery, and quality of life for both versions of the IMRS. These findings support the utility of the IMRS as a measure of illness self-management and recovery in clients with schizophrenia.

A randomized controlled trial of the illness management and recovery program for persons with schizophrenia.

OBJECTIVE: The aim of the study was to evaluate the effects of the illness management and recovery (IMR) program on symptoms and psychosocial functioning of individuals with schizophrenia or schizoaffective disorder in an outpatient setting in Sweden. METHODS: A total of 41 persons with schizophrenia or schizoaffective disorder who were receiving treatment at six psychiatric outpatient rehabilitation centers were randomly assigned to either an IMR group for nine months or to treatment as usual (control condition). Assessments were conducted at baseline, posttreatment (nine months), and follow-up (21 months) and included self-reports and ratings by clinicians (both blind and nonblind to treatment assignment) of illness management, psychiatric symptoms, recovery, coping, quality of life, hospitalization, insight, and suicidal ideation. RESULTS: As measured by self-report and ratings of nonblinded clinicians, IMR program participants demonstrated significantly greater improvement in illness management than participants in the control condition. Ratings of psychiatric symptoms by blinded clinicians using the Psychosis Evaluation Tool for Common Use by Caregivers and self-reported ratings of psychosocial functioning on the Ways of Coping Questionnaire also showed better outcomes than for participants in treatment as usual. A statistically significant decrease in suicidal ideation between baseline and follow-up was found for IMR program participants. CONCLUSIONS: The study supports previous findings and suggests that the IMR program is effective in improving the ability of individuals with schizophrenia to better manage their illness.

Effects of heart rate variability biofeedback in subjects with stress-related chronic neck pain: a pilot study.

Recent studies focusing on autonomic nervous system (ANS) dysfunctions, together with theoretical pathophysiological models of musculoskeletal disorders, indicate the involvement of ANS regulation in development and maintenance of chronic muscle pain. Research has demonstrated the effectiveness of heart rate variability (HRV) biofeedback (BF) in increasing HRV and reducing the symptoms of different disorders characterized by ANS aberration. The study investigated the effects of resonance frequency HRV BF on autonomic regulation and perceived health, pain, stress and disability in 24 subjects with stress-related chronic neck-shoulder pain. Twelve subjects participated in 10 weekly sessions of resonant HRV BF and were compared to a control group. Subjective reports and HRV measures during relaxation and in response to a standardized stress protocol were assessed for both groups pre- and post-intervention. Group × time interactions revealed a significantly stronger increase over time in perceived health (SF-36) for the treatment group, including vitality, bodily pain and social functioning. Interactions were also seen for HRV during relaxation and reactivity to stress. The present pilot study indicates improvement in perceived health over a 10 week intervention with HRV-biofeedback in subjects with chronic neck-pain. Increased resting HRV as well as enhanced reactivity to hand grip and cold pressor tests might reflect beneficial effects on ANS regulation, and suggest that this intervention protocol is suitable for a larger controlled trial.

A randomized controlled effectiveness trial of parent management training with varying degrees of therapist support.

This study examined the effectiveness of a Swedish parent management training (PMT) intervention for parents of children aged 3 to 10 within the context of regular social service. Self-referred parents of 159 children (aged 3 to 10) with conduct problems were randomly assigned to either 11 practitioner-assisted group sessions (PMT-P), or a single instructional workshop followed by self-administration of the training material (PMT-S), or a waitlist control group. Intent-to-treat analyses showed that both PMT-P and PMT-S improved parent competence and reduced child conduct problems compared to the waitlist at posttest. Both training conditions showed further significant improvements at the 6-month follow-up. In direct comparison, PMT-P was superior to PMT-S on measures of child conduct problems at both posttest and follow-up. Improvement in child conduct was mediated by improvement in parent competencies and homework fidelity. The findings in this study have implications for large-scale dissemination of parent management training through different means of delivery.

The Chronic Pain Acceptance Questionnaire (CPAQ)-further validation including a confirmatory factor analysis and a comparison with the Tampa Scale of Kinesiophobia.

Acceptance of pain and distress has lately appeared as an important factor in determining peoples' ability to restore functioning in the presence of chronic pain. Although treatments based on cognitive behaviour therapy are beginning to incorporate acceptance strategies, there is still a lack of reliable and valid instruments to assess relevant processes in such interventions. The Chronic Pain Acceptance Questionnaire (CPAQ) was originally constructed as part of the development of an acceptance oriented treatment approach for pain patients. A revised 20-item version of the instrument with two subscales has shown adequate reliability and validity. In the present study, a Swedish translation of CPAQ was evaluated with 611 participants reporting chronic pain and symptoms of whiplash associated disorders. This study sought to further assess the psychometric properties of the instrument and to investigate its relation to another important measure of pain adjustment, the Tampa Scale of Kinesiophobia. Due to low intercorrelations with other items, item 16 was excluded. Exploratory and confirmatory factor analyses supported the previously suggested two-factor solution. Furthermore, the internal consistencies were good for the subscales (activities engagement and pain willingness) as well as the total scale. Hierarchical regression analyses illustrated strong relations with criteria variables (e.g. disability and life satisfaction). In general, the activities engagement subscale contributed more than pain willingness to the prediction of criteria variables. Furthermore, results illustrated that CPAQ explained more variance than the Tampa Scale of Kinesiophobia in pain intensity, disability, life satisfaction, and depression.

Evaluating the effectiveness of exposure and acceptance strategies to improve functioning and quality of life in longstanding pediatric pain--a randomized controlled trial.

Although several studies have illustrated the effectiveness of cognitive behavior therapy (CBT) on adult pain patients, there are few randomized controlled trials on children and adolescents. There is particularly a need for studies on pediatric patients who are severely disabled by longstanding pain syndromes. Acceptance and Commitment Therapy, as an extension of traditional CBT, focuses on improving functioning and quality of life by increasing the patient's ability to act effectively in concordance with personal values also in the presence of pain and distress. Following a pilot study, we sought to evaluate the effectiveness of an ACT-oriented intervention based on exposure and acceptance strategies and to compare this with a multidisciplinary treatment approach including amitriptyline (n=32). The ACT condition underwent a relatively brief treatment protocol of approximately 10 weekly sessions. Assessments were made before and immediately after treatment, as well as at 3.5 and 6.5 months follow-up. Prolonged treatment in the MDT group complicated comparisons between groups at follow-up assessments. Results showed substantial and sustained improvements for the ACT group. When follow-up assessments were included, ACT performed significantly better than MDT on perceived functional ability in relation to pain, pain intensity and to pain-related discomfort (intent-to-treat analyses). At post-treatment, significant differences in favor of the ACT condition were also seen in fear of re/injury or kinesiophobia, pain interference and in quality of life. Thus, results from the present study support previous findings and suggest the effectiveness of this ACT-oriented intervention for pediatric longstanding pain syndromes.

Can exposure and acceptance strategies improve functioning and life satisfaction in people with chronic pain and whiplash-associated disorders (WAD)? A randomized controlled trial.

Although 14% to 42% of people with whiplash injuries end up with chronic debilitating pain, there is still a paucity of empirically supported treatments for this group of patients. In chronic pain management, there is increasing consensus regarding the importance of a behavioural medicine approach to symptoms and disability. Cognitive behaviour therapy has proven to be beneficial in the treatment of chronic pain. An approach that promotes acceptance of, or willingness to experience, pain and other associated negative private events (e.g. fear, anxiety, and fatigue) instead of reducing or controlling symptoms has received increasing attention. Although the empirical support for treatments emphasizing exposure and acceptance (such as acceptance and commitment therapy) is growing, there is clearly a need for more outcome studies, especially randomized controlled trials. In this study, participants (N = 21) with chronic pain and whiplash-associated disorders were recruited from a patient organization and randomized to either a treatment or a wait-list control condition. Both groups continued to receive treatment as usual. In the experimental condition, a learning theory framework was applied to the analysis and treatment. The intervention consisted of a 10-session protocol emphasizing values-based exposure and acceptance strategies to improve functioning and life satisfaction by increasing the participants' abilities to behave in accordance with values in the presence of interfering pain and distress (psychological flexibility). After treatment, significant differences in favor of the treatment group were seen in pain disability, life satisfaction, fear of movements, depression, and psychological inflexibility. No change for any of the groups was seen in pain intensity. Improvements in the treatment group were maintained at 7-month follow-up. The authors discuss implications of these findings and offer suggestions for further research in this area.

Acceptance and Commitment Therapy and yoga for drug-refractory epilepsy: a randomized controlled trial.

OBJECTIVE: There is a need for controlled outcome studies on behavioral treatment of epilepsy. The purpose of this study was to evaluate Acceptance and Commitment Therapy (ACT) and yoga in the treatment of epilepsy. METHODS: The design consisted of a randomized controlled trial with repeated measures (N=18). All participants had an EEG-verified epilepsy diagnosis with drug-refractory seizures. Participants were randomized into one of two groups: ACT or yoga. Therapeutic effects were measured using seizure index (frequency x duration) and quality of life (Satisfaction with Life Scale, WHOQOL-BREF). The treatment protocols consisted of 12 hours of professional therapy distributed in two individual sessions, two group sessions during a 5-week period, and booster sessions at 6 and 12 months posttreatment. Seizure index was continuously assessed during the 3-month baseline and 12-month follow-up. Quality of life was measured after treatment and at the 6-month and 1-year follow-ups. RESULTS: The results indicate that both ACT and yoga significantly reduce seizure index and increase quality of life over time. ACT reduced seizure index significantly more as compared with yoga. Participants in both the ACT and yoga groups improved their quality of life significantly as measured by one of two quality-of-life instruments. The ACT group increased their quality of life significantly as compared with the yoga group as measured by the WHOQOL-BREF, and the yoga group increased their quality of life significantly as compared with the ACT group as measured by the SWLS. CONCLUSIONS: The results of this study suggest that complementary treatments, such as ACT and yoga, decrease seizure index and increase quality of life.

Avoidance and cognitive fusion--central components in pain related disability? Development and preliminary validation of the Psychological Inflexibility in Pain Scale (PIPS).

Acceptance of pain and other associated negative private experiences has received increasing attention in recent years. This approach is in stark contrast to the traditional approach of reducing or controlling symptoms of pain. The empirical support for treatments emphasizing exposure and acceptance, such as Acceptance and Commitment Therapy, is growing. However, to date, few instruments exist to assess the core processes in these types of treatments. This study describes the development and preliminary validation of the Psychological Inflexibility in Pain Scale. Principal components analysis (PCA) suggests a 2-factor solution with a total of 16 items measuring avoidance of pain and cognitive fusion with pain. Results also indicate adequate reliability and validity for the scale. Implications of these findings for clinical assessment, as well as for research on pain related disability, are discussed along with suggestions for further research in this area.

Relation problems in internationally adopted juvenile delinquents.

OBJECTIVE: Internationally adopted delinquents are overrepresented in juvenile Swedish institutions. With the purpose of investigating possible reasons for this overrepresentation, this study compared adopted delinquent adolescents and internationally adopted controls in the structure and functioning of their current relations, especially with their parents. METHODS: Internationally adopted adolescents admitted to institutional care (N=20) and non-delinquent internationally adopted controls (N=21) were compared through: a questionnaire; "family relations", a subscale in I think I am; "Family climate" (from Karolinska Scale of Personality); Individual Schedule of Social Interaction; and an Attachment Test. RESULTS: Bad relations with adoptive parents were more prevalent in internationally adopted delinquents compared to internationally adopted controls. Furthermore, the adopted delinquents and their parents blamed each other for the problems and the adopted delinquents reported physical and emotional abuse. CONCLUSIONS: Internationally adopted delinquents reported more problems in their relationships to their parents than adopted controls did.

Exposure and acceptance in the rehabilitation of adolescents with idiopathic chronic pain - a pilot study.

For chronic pain of unclear origin (idiopathic), pharmacological therapy is often insufficient. Psychological treatment strategies have been developed and evaluated for adults with chronic pain. However, few such studies are seen with youths, and to date there is limited empirical evidence regarding the effectiveness of psychological treatment for generalized musculoskeletal pain syndromes in adolescents. Acceptance and commitment therapy (ACT) is a development of cognitive behaviour therapy emphasizing exposure and acceptance. In this pilot study, 14 adolescents referred to the pain treatment service due to chronic debilitating pain were treated using an ACT-based approach. It was hypothesized that avoidance of pain and related stimuli was central to the disability seen among these patients, and that exposure and acceptance strategies could increase functioning and decrease pain. In contrast to emphasizing reductions in pain and distress, the treatment objective was to improve functioning by increasing the patient's ability to act in line with personal values in the presence of negative thoughts, emotions or bodily sensations. Following treatment, and retained at 3- and 6-month follow-up, improvements in functional ability, school attendance, catastrophizing and pain (i.e., intensity and interference) were seen. The outcome of this pilot study indicates that exposure and acceptance can been useful in the rehabilitation of adolescents with chronic debilitating pain. Randomized controlled studies are needed to empirically evaluate the effectiveness of this approach.
