The Role of Illness Perceptions in Predicting Outcome After Acute Whiplash Trauma: A Multicenter 12-month Follow-up Study

Changes in illness perception, pain catastrophizing, and psychological distress following hand surgeon consultation: A prospective study

BACKGROUND

Baseline mindset factors are important factors that influence treatment decisions and outcomes. Theoretically, improving the mindset prior to treatment may improve treatment decisions and outcomes. This prospective cohort study evaluated changes in patients' mindset following hand surgeon consultation. Additionally, we assessed if the change in illness perception differed between surgical and nonsurgical patients.

METHODS

The primary outcome was illness perception, measured using the total score of the Brief Illness Perception Questionnaire (B-IPQ, range 0-80). Secondary outcomes were the B-IPQ subscales, pain catastrophizing (measured using the Pain Catastrophizing Scale (PCS)), and psychological distress (measured using the Patient Health Questionnaire-4).

RESULTS

A total of 276 patients with various hand and wrist conditions completed the mindset questionnaires before and after hand surgeon consultation (median time interval: 15 days). The B-IPQ total score improved from 39.7 (±10.6) before to 35.8 (±11.3) after consultation (p < 0.0001, Cohen's d = 0.36); scores also improved for the B-IPQ subscales Coherence, Concern, Emotional Response, Timeline, Treatment Control, and Identity and the PCS. There were no changes in the other outcomes. Surgical patients improved on the B-IPQ subscales Treatment Control and Timeline, while nonsurgical patients did not.

CONCLUSIONS

Illness perception and pain catastrophizing improved following hand surgeon consultation, suggesting that clinicians may actively influence the patients' mindset during consultations, and that they may try to enhance this effect to improve outcomes. Furthermore, surgical patients improved more in illness perceptions, indicating that nonsurgical patients may benefit from a more targeted strategy for changing mindset.

Recovery expectations can be assessed with single-item measures: findings of a systematic review and meta-analysis on the role of recovery expectations on return-to-work outcomes after musculoskeletal pain conditions

ABSTRACT

The objective of this systematic review is to quantify the association between recovery expectations and return-to-work outcomes in adults with musculoskeletal pain conditions. In addition, this review has the second objective to compare the predictive utility of single-item and multi-item recovery expectation scales on return-to-work outcomes. Relevant articles were selected from Embase, PsycINFO, PubMed, Cochrane, and manual searches. Studies that assessed recovery expectations as predictors of return-to-work outcomes in adults with musculoskeletal pain conditions were eligible. Data were extracted on study characteristics, recovery expectations, return-to-work outcomes, and the quantitative association between recovery expectations and return-to-work outcomes. Risk of bias was assessed using the Effective Public Health Practice Project. Odds ratios were pooled to examine the effects of recovery expectations on return-to-work outcomes. Chi-square analyses compared the predictive utility of single-item and multi-item recovery expectation scales on return-to-work outcomes. Thirty studies on a total of 28,741 individuals with musculoskeletal pain conditions were included in this review. The odds of being work disabled at follow-up were twice as high in individuals with low recovery expectations (OR = 2.06 [95% CI 1.20-2.92] P < 0.001). Analyses also revealed no significant differences in the predictive value of validated and nonvalidated single-item measures of recovery expectations on work disability (χ 2 = 1.68, P = 0.19). There is strong evidence that recovery expectations are associated with return-to-work outcomes. The results suggest that single-item measures of recovery expectations can validly be used to predict return-to-work outcomes in individuals with musculoskeletal pain conditions.

Improved quality of physiotherapy care in patients with Whiplash-Associated Disorders: Results based on 16 years of routinely collected data

Quality improvement is now a central tenet in physiotherapy care, and quality indicators (QIs), as measurable elements of care, have been applied to analyze and evaluate the quality of physiotherapy care over the past two decades. QIs, based on Donabedian's model of quality of care, provide a foundation for measuring (improvements in) quality of physiotherapy care, providing insight into the many remaining evidentiary gaps concerning diagnostics, prognostics and treatment, as well as patient-related outcome measures. In this overview we provide a synthesis of four recently published articles from our project group on the topic of quantitative measures of quality improvement in physiotherapy care, in this context specifically focused on patients with WAD in primary care physiotherapy. A set of process and outcome QIs (n = 28) was developed for patients with WAD and linked to a database consisting of routinely collected data (RCD) on patients with WAD collected over a 16-year period. The QIs were then embedded per step of the clinical reasoning process: (a) administration (n = 2); (b) history taking (n = 7); (c) objectives of examination (n = 1); (d) clinical examination (n = 5); (e) analysis and conclusion (n = 1); (f) treatment plan (n = 3); (g) treatment (n = 2); (h) evaluation (n = 5); and (i) discharge (n = 2). QIs were expressed as percentages, allowing target performance levels to be defined ≥70% or ≤30%, depending on whether the desired performance required an initially high or low QI score. Using RCD data on primary care patients with WAD (N = 810) and a set of QIs, we found that the quality of physiotherapy care has improved substantially over a 16-year period. This conclusion was based on QIs meeting predetermined performance targets of ≥70% or ≤30%. Twenty-three indicators met the target criterium of ≥70% and three indicators ≤30%. Our recommended set of QIs, embedded in a clinical reasoning process for patients with WAD, can now be used as a basis for the development of a validated QI set that effectively measures quality (improvement) of primary care physiotherapy in patients with WAD.

Attachment and symptom reporting in adolescents and young adults after a concussion

BACKGROUND

The incidence of hospital-treated concussion is 100-300/100,000 person years. Reporting of long-lasting post-concussion symptoms (PCS) is estimated at 5-15%. Attachment insecurity is a potential vulnerability factor for physical illness and poorer disease outcomes in general. This study aimed to explore associations between attachment insecurity and PCS in young people sustaining a concussion.

METHODS

This cross-sectional study was embedded in a cohort of 15-30-year-old patients (n = 3080) 3 months after sustaining a concussion. Data were obtained from a database and questionnaires. PCS were measured by the Rivermead Post-Concussion Symptoms Questionnaire and attachment dimensions (anxiety and avoidance) by the Experiences in Close Relationships-Relationship Structures Questionnaire. Multiple linear regression models were performed to investigate the association between the attachment dimensions and PCS with adjustment for demographic, injury-related and psychological factors and with additional testing for interaction between the attachment dimensions.

RESULTS

In the final study sample, comprising 973 patients (31.6%), we found an interaction between the attachment dimensions. Hence, the effect of attachment anxiety on PCS was statistically insignificant at low avoidance (25th percentile) but significant at high avoidance (75th percentile, β = 0.64 (95%CI: 0.02; 1.26)), whereas the effect of attachment avoidance was significant regardless of level of attachment anxiety (25th percentile, β = 1.09 (95%CI: 0.18; 2.01); 75th percentile, β = 2.71 (95%CI: 1.80; 3.61)).

CONCLUSION

Attachment insecurity, especially characterised by high avoidance in combination with high anxiety, also called fearful attachment, is associated with PCS. Considering the attachment perspective can potentially improve health care for this patient group.

Return to work a bumpy road: a qualitative study on experiences of work ability and work situation in individuals with chronic whiplash-associated disorders

Background

Work resumption is a big challenge in the rehabilitation process for individuals with whiplash-associated disorders (WAD). To better meet the needs of individuals with WAD in their return to work process, more knowledge on their experiences and perspectives is needed. The aim of this study was to explore the experiences of work ability and the work situation of individuals who participated in a neck-specific exercise programme for chronic WAD.

Methods

This qualitative study has an exploratory and descriptive design based on data collected through open-ended interviews with 17 individuals with chronic WAD. Data were analysed inductively using conventional content analysis.

Results

Analysis of the data yielded the following five categories related to the participants’ narratives on their experiences of work ability and their work situation: Return to work – a process of setbacks and bureaucracy; The need to be understood by health care professionals, and to receive a treatment plan; Individual resources are important for work ability; The consequences of reduced work ability; and Working conditions are important for work ability.

Conclusion

Individuals with chronic WAD often struggle to return to work. Emotional and practical support from stakeholders is imperative and needs to be strengthened. Participating in a neck-specific exercise programme, including being acknowledged and receiving information about WAD, could positively affect the work ability of WAD sufferers. This study has provided management strategies to improve the ability to work for individuals with chronic WAD, and highlights the need to incorporate a healthy and sustainable return to work in the rehabilitation of individuals with WAD, thereby making their return to work a success.

Revisiting Risk-stratified Whiplash-exposed Patients 12 to 14 Years After Injury

OBJECTIVE

The objective of this study was to evaluate the long-term predictive value of the Danish Whiplash Group Risk Assessment Score (DWGRAS) with 7 risk strata.

DESIGN

E-questionnaire-based follow-up study (n=927) combining 2 cohorts of whiplash-injured patients, 1 observational (n=187) and 1 interventional randomized controlled trial (n=740).

METHODS

Nine hundred twenty-seven previously healthy persons exposed to acute whiplash injury during motor vehicle collision were sent letter by postal service asking the addressee if they would respond to an E-questionnaire. Outcome measures were: whiplash-related disability, pain, use of medication/nonmedical treatment, work capacity.

RESULTS

The response rate was 37%. Fifty-five percent reported whiplash-related disability. Fourteen percent reported daily symptoms. A strong relationship was found between risk strata and impact of event and between risk strata and disabling symptoms.

CONCLUSIONS

Internal and long-term validation of DWGRAS was performed, but a low response rate indicates that results should be interpreted with caution. Furthermore, external validation needs to be done in long-term studies. An receiver operating characteristics curve of 0.73 (95% confidence interval 0.67; 0.79) predicting daily or weekly whiplash-related disability after 12 to 14 years was found using the DWGRAS risk score.

Precollision Medical Diagnoses Predict Chronic Neck Pain Following Acute Whiplash Trauma

OBJECTIVES

The reason why some individuals develop chronic symptoms, whiplash-associated disorder, following whiplash trauma is poorly understood. We explored whether precollision pain-related diagnoses, medically unexplained symptoms, and psychiatric diagnoses are related to whiplash-associated disorder.

MATERIALS AND METHODS

A cohort of 719 individuals exposed to whiplash trauma and subsequently experiencing symptoms within 72 hours (whiplash-exposed cohort) and 3595 matched controls were included in this observational prospective study. At 12 months postcollision, the whiplash-exposed cohort rated their neck pain using the Visual Analog Scale. Data on health were obtained from the Danish National Patient Register for the whiplash-exposed cohort and for the controls for a 5-year period before collision.

RESULTS

The whiplash-exposed cohort had significantly increased incidences of precollision pain-related diagnoses: χ(1)=17.42, P<0.001 and medically unexplained symptoms: χ(1)=22.2, P<0.001 but not psychiatric diagnoses: χ(1)=3.60, P>0.05 compared with controls in the 5-year period. Participants from the whiplash-exposed cohort with precollision pain-related diagnoses (odds ratio=2.46; 95% confidence interval, 1.39; 4.35) and medically unexplained symptoms (odds ratio, 1.72; 95% confidence interval, 1.04; 2.84) had significantly increased odds for neck pain at follow-up.

DISCUSSION

Precollision pain and medically unexplained symptoms predict chronic neck pain following whiplash trauma. This may indicate that a sensitization process was initiated before the collision or that individuals with precollision low threshold for contacting health care services maintain this behavior postcollision. The collision may trigger existing individual vulnerabilities that constitute to be a risk factor for chronic whiplash.

Illness Perceptions of Patients With First Carpometacarpal Osteoarthritis, Carpal Tunnel Syndrome, Dupuytren Contracture, or Trigger Finger

PURPOSE

Previous studies indicate that patients with a more negative perception of their illness tend to respond less favorably to treatment, but little is known about whether illness perceptions differ based on the type of hand or wrist conditions. Therefore, we compared illness perceptions between patients scheduled to undergo surgery for 4 illnesses in hand surgery: carpometacarpal osteoarthritis (CMC OA), Dupuytren disease, carpal tunnel syndrome (CTS), and trigger finger syndrome (TFS). We hypothesized there would be differences in illness perception between these patient groups.

METHODS

Before surgery, patients were asked to complete the Brief Illness Perception Questionnaire (Brief-IPQ) as part of routine outcome measurement in a specialized hand and wrist surgery clinic. The Brief-IPQ is a validated questionnaire to rapidly assess the cognitive and emotional representation of illness. Differences in illness perception between the 4 diagnostic groups, corrected for age, sex, hand dominance, and work type, were examined. Cohen D effect sizes were calculated for the between-group differences.

RESULTS

We included 514 patients in the analyses: 87 with CMC OA, 146 with Dupuytren disease, 129 with CTS, and 152 with TFS. On a scale ranging from 0 (most positive perception) to 80 (most negative perception) the Brief-IPQ sum scores for these subgroups were 42.0, 28.2, 38.8, and 33.3, respectively. Corrected for age, sex, hand dominance, and work type, patients with Dupuytren disease had a more positive perception of their illness than patients with CMC OA and CTS. Compared with CMC OA patients, the effect sizes for Dupuytren, CTS, and TFS patients were, respectively, 1.28, 0.32, and 0.81.

CONCLUSIONS

In these patients with various hand/wrist disorders, differences were found in their preoperative perceptions of illness. Interventions that directly target negative illness perceptions might improve treatment outcomes for CMC OA and CTS.

CLINICAL RELEVANCE

These differences should be considered during preoperative medical consultations and/or when investigating surgical outcomes.

Clinical Characteristics and Patient-Reported Outcomes of Primary Care Physiotherapy in Patients with Whiplash-Associated Disorders: A Longitudinal Observational Study

BACKGROUND

Whiplash-associated disorders (WADs) constitute a state of health characterized by a wide diversity of symptoms as a result of impairments of functions, activity limitations, and participation restrictions. Patient-reported outcome measurements (PROMs) and patient-reported outcomes (PROs) seem appropriate when describing and evaluating the health status of patients with WAD.

AIM

To measure the use of PROMs and PROs as quality indicators in clinical reasoning, and to analyze and evaluate pre- and post-treatment 'pain intensity' and 'functioning', and for 'perceived improvement' in patients with WAD in primary care physiotherapy practice by year of referral, with the phase after accident and prognostic health profile embedded in the clinical reasoning process.

MATERIALS AND METHODS

Data were collected over a period of 10 years. Pain intensity, functioning, and perceived improvement were measured using the Visual Analogue Scale for Pain (VAS-P), the Neck Disability Index (NDI) and the Global Perceived Effect scale (GPE). Pre- and post-treatment mean differences were tested for statistical significance and compared to minimal clinically important differences (MCID). Effect sizes were expressed as Cohen's d. Multivariable regression analysis was performed to explore independent associations of year of referral, phase after the accident, and the patient's prognostic health profile with post-treatment pain intensity and functioning.

RESULTS

A consecutive sample of 523 patients was included. Pre- and post-treatment mean differences on VAS-P and NDI were statistically significant (P<0.000) and clinically relevant, with 'large' effect sizes for pain intensity and functioning. MCIDs were achieved by 80% for VAS-P and for 60% for NDI. Year of referral and phase after the accident were independently associated with worse post-treatment functioning. About half of the patients (n=241 [46.1%]) perceived themselves as improved.

CONCLUSION

The PROMs and PROs pain intensity, functioning and perceived improvement were integrated as quality indicators in the physiotherapy clinical reasoning process for patients with WAD. Significant differences in pain intensity and functioning were found but were unrelated to year of referral, phase after whiplash-related injury or prognostic health profile. The MCID VAS-P scores did not differ depending on experienced pain.

Application of ICD-11 among individuals with chronic pain: A post hoc analysis of the Stanford Self-Management Program

BACKGROUND

Chronic primary pain (CPP) is one of seven diagnostic groups within the proposed classification of chronic pain in ICD-11. Our aims were to apply the proposed ICD-11 criteria in a large cohort of chronic pain patients participating in the Chronic Pain Self-Management Program (CPSMP) and further investigate whether participants with CPP differed from participants with chronic secondary pain (CSP) regarding health, health expenditure and the effect of participating in the CPSMP.

METHODS

A secondary analysis of a randomized, controlled trial on the effect of the CPSMP. Four examiners categorized participants' pain according to ICD-11 using register-based medical diagnoses and patients' self-reported symptoms. Afterwards, differences between CPP and CSP were examined.

RESULTS

Out of 394 participants, 312 were successfully classified into CPP (n = 164) or CSP (n = 148) whereas 76 had a mixed pain condition. Participants with CPP were younger, more likely to be women, and had longer pain duration compared to participants with CSP. Participants with CPP reported worse health-related quality of life on the SF-36 Mental Component Summary and subscales of vitality, social functioning and bodily pain. Participants with CSP had more physical comorbidities and higher total health expenditure. None of the groups benefitted from the CPSMP.

CONCLUSIONS

We successfully applied the new classification of chronic pain in ICD-11 on the basis of ICD-10 medical diagnoses and symptom self-report. Participants with CPP differed significantly from participants with CSP on baseline characteristics, self-reported health measures and total health expenditure. The CPSMP was not effective in any of the groups.

SIGNIFICANCE

The current study applies the proposed new classification of chronic pain in ICD-11 and shares the experiences of the diagnostic rating procedure of individuals with chronic pain. Furthermore, it evaluates the effect of the Stanford Self-Management Program.

Effect of Illness Perception Correction - Based Educational Program on Quality Of Life and Self- Care in Patients with Heart Failure: a Randomized Controlled Trial

Introduction: Because of the chronic nature of Heart Failure (HF), low Quality of Life (QoL) and poor self-care are prevalent among patients with HF. Thus, the aim of this study was to evaluate the effect of illness perception correction- based educational program on QoL,and self- care in patients with HF.

Methods: In this randomized controlled trial, 78 eligible patients were included in the study from Rajaei Heart Center (Tehran, Iran) and randomly assigned into intervention and control group with 1:1 allocation ratio. The intervention was a combination of illness perception correction- based education program (30- minute sessions over 3 consecutive days) and 10-minute phone calls made once a week in the course of 8 weeks. The control group received usual care. The primary outcome was quality of life and secondary outcomes were self- care and illness- perception which were measured at baseline and at the end of the study. SPSS version 13 was used for the analysis.

Results: Out of 76 eligible patients, 70 patients with HF finished the study. Although the mean of quality of life, self-care, and illness perception were not different at baseline, QoL (45.2 (8.3) VS 66.8 (15.4); P<0.001), self-care (18.5 (4.5) VS 37.1 (7.2); P<0.001), and illness- perception (183.6 (8.4) VS 151.2 (24.5); P<0.001) improved following the program in the intervention group in comparison to the control group.

Conclusion: According to the study findings, this program can be applied by nurses for patients with HF as a discharge plan in order to improve their QoL, self-care, and their illness perception.

Development of an Internet-delivered educational video for acute whiplash injuries

Objective

To describe the development of a preventive educational video for patients exposed to whiplash trauma following motor vehicle accidents.

Methods

The development followed a systematic approach and was theory-driven supplemented with available empirical knowledge. The specific content was developed by a multidisciplinary group involving health professionals and visual production specialists.

Results

A 14-min educational video was created. The video content focuses on stimulating adaptive recovery expectations and preventing maladaptive illness beliefs. The video presents a multifactorial model for pain incorporating physiological and cognitive-behavioural aspects, advice on pain relief, and exercises. Subjects interviewed for a qualitative evaluation found the video reassuring and that it aligned well with verbal information received in the hospital.

Conclusions

The development of the visual educational intervention benefitted from a systematic development approach entailing both theoretical and research-based knowledge. The sparse evidence on educational information for acute whiplash trauma posed a challenge for creating content. Further knowledge is required regarding what assists recovery in the early stages of whiplash injuries in order to improve the development of educational interventions.

Revisiting the Cognitive Model of Depression: The Role of Expectations

The cognitive model of depression was highly stimulating for a better understanding and development of treatment for depression. However, the concept of “cognition” is rather broad and unspecific, and we suggest to focus on the cognitive subset of expectation.

We conducted a narrative review on the role of expectations, and present an expectation-focused model of explaining why depression tends to persist despite the occurrence of positive events.

Several results from basic neuroscience to effects in clinical interventions indicate that expectations play a special role not only for the understanding of the development of mental disorders and the effects of treatment approaches, but especially for an improved understanding of the persistence of mental disorders. If expectations are a major mechanism of depression, the treatment of depression must maximize the violation of dysfunctional expectations. We also introduce the concept of immunization that describes any cognitive or behavioral strategies to reduce the effect of expectation violation experiences, and hereby contributing to expectation maintenance despite expectation contradicting events. We postulate that the development of immunization strategies could help to better understand the transition from episodic to chronic depression.

While in early periods of depression development, a focus on expectation change might be sufficient in treatment, the treatment of patients with chronic depression requires addressing these cognitive and behavioral immunization strategies more intensively. Further implications for treatment and research are outlined that are derived from this balance between expectation violation and cognitive immunization in depression.

A focus on “expectations” helps to better understand the maintenance of depression

We offer a model that explains why depression persists even in the presence of positive experiences.

Many psychological treatments focus on the violation of negative expectations, but cognitive immunization can hinder treatment success.

We suggest strategies on how to improve psychological treatments for depression by maximizing expectation violation, and minimizing cognitive immunization.

Illness perception in people with primary and secondary chronic headache in the general population

BACKGROUND

Chronic headache (headache ≥15 days/month) is a leading cause of disability. Illness perception, beliefs and cognitive models are likely central for patient understanding of their chronic pain condition and are associated with treatment outcome. However, these factors are insufficiently described in chronic headache.

OBJECTIVE

To describe illness perception, and to explore the effect of background variables and headache characteristics on illness perceptions in primary and secondary chronic headaches in the general population.

METHODS

30,000 persons aged 3044 from the general population were screened for chronic headache by a mailed questionnaire. Those with self-reported chronic headache were interviewed by headache specialists. The questionnaire response rate was 71%, and the interview participation rate was 74%. The International Classification of Headache Disorders III was applied. Illness perception was assessed by the Revised Illness Perception Questionnaire (IPQ-R). The statistical approach was exploratory.

RESULTS

405 of the 516 eligible participants (78%) completed the IPQ-R. Confirmatory factor analysis showed good internal validity in chronic headache. People believed their chronic headache to be long-lasting, with negative life consequences including emotional distress. Severe headache-related disability was associated with more perception of chronicity, more perceived consequences, emotional load and illness identity and less illness coherence. People with secondary chronic headache scored significantly higher on chronicity and life consequences, and had less personal control than those with primary chronic headache.

CONCLUSION

Chronic primary and secondary headache is associated with a high symptom burden and chronicity with large perceived negative consequences for daily living, suggesting multidisciplinary management may be necessary.

The experiences and beliefs of patients with complex regional pain syndrome: An exploratory survey study

Objectives To determine the beliefs and describe the health care experiences of patients with complex regional pain syndrome. Methods A survey tool for patients with complex regional pain syndrome was designed for this study. The survey tool collected self-reported measures associated with pain, disability, health care experiences, education, beliefs, and treatments. Results Thirty-one patients attending physical therapy for complex regional pain syndrome (mean age 40.48; female n = 20) completed the survey. Patients with presented with high levels of pain and disability and reported various changes associated with altered neuroplasticity such as confused body part recognition, left/right discrimination, neglect, and spreading pain. The patients' experiences with diagnostic testing and interventions are not in line with the current pain science research and/or evidence-based practice. Overall, patients are ill-informed, confused, and receive conflicting information. Discussion The suffering associated with complex regional pain syndrome is real, as told by patients. This suffering coincides with a lack of consensus by health care providers and conflicting information on complex regional pain syndrome. Overall, patient experiences show health care providers are not up to date with the current best-evidence regarding complex regional pain syndrome.

Expectation of a Decrease in Pain Affects the Prognosis of Pain in Cancer Patients: a Prospective Cohort Study of Response to Morphine

Purpose

Cancer pain is a multidimensional experience that includes physiological, sensory, affective, cognitive, behavioral, and sociocultural dimensions. Few prospective studies have examined the relationship between a patient’s expectation of pain improvement and the pain prognosis. The aim of this prospective study was to investigate whether patients’ expectation to pain reduction was associated with pain intensity after morphine treatment in opioid treatment-naïve patients with various types of cancer.

Methods

The subjects were patients scheduled for cancer pain treatment with morphine who were taking nonsteroidal anti-inflammatory drugs daily. Morphine treatment was performed according to the standard method, including titration (NCCN Guidelines™, Adult Cancer Pain). Simple regression analysis was performed between pain intensity numerical rating scale (NRS) (day 8) as the dependent variable, expectation of pain decrease NRS (day 1), tumor types, and the following covariates as independent variables: patients’ characteristics such as age, gender, PS (day 1), genotype of catechol-O-methyltransferase, total scores of Hospital Anxiety and Depression Scale (day 1), and pain intensity NRS (day 1). Multiple regression analysis was performed using forced entry methods with pain intensity NRS (day 8) as the dependent variable, and expectation of pain decrease NRS (day 1) and the covariates as independent variables that had a p value <0.05 in the simple regression models.

Results

A total of 100 patients with baseline data were included, and 97 patients (51% female) met the inclusion criteria. Patients with a high expectation of pain decrease NRS had a significantly lower pain intensity NRS (day 8) (p = 0.001).

Conclusion

Non-pharmacological factors such as expectations for pain treatment could also be important factors to treat cancer pain, which might be associated with communication skills in physicians.

Health anxiety by proxy in women with severe health anxiety: A case control study

Health anxiety (HA) refers to excessive worries and anxiety about harbouring serious illness based on misinterpretation of bodily sensations or changes as signs of serious illness. Severe HA is associated with disability and high health care costs. However, the impact of parental HA on excessive concern with their children's health (health anxiety by proxy) is scantly investigated. The aim of this study is to investigate HA by proxy in mothers with severe HA. Fifty mothers with severe HA and two control groups were included, i.e. mothers with rheumatoid arthritis (N=49) and healthy mothers (N=51). All participants completed self-report questionnaires on their own HA and illness perceptions and on illness worries and illness behaviour related to their children. The results showed that mothers with severe HA reported significantly more negative illness perceptions and more HA on behalf of their child (i.e. by proxy) compared to both control groups. HA by proxy may be an overlooked treatment target in mothers with severe HA, and improving our understanding of this condition can have important preventive and clinical implications.

De-educate to re-educate: aging and low back pain

BACKGROUND

Patients' beliefs about their condition have been shown to play a significant role in their pain experience and response to treatment, especially when a patient sees their tissue health as vulnerable or aged. Educational can alter these beliefs. Prior to new information, patients often have to be de-educated regarding common misbeliefs to undergo re-education.

AIMS

To determine if a brief de-education session regarding aging and low back pain (LBP) can shift pain ratings, fear-avoidance beliefs, beliefs regarding aging and LBP, and limited active trunk flexion.

METHODS

Fifty adults ranging from 50 to 93 years of age (SD = 10.73) with a 15.1 years of LBP were education on the poor correlation between aging and LBP. Prior to and immediately after the education pain ratings for LBP and leg pain (numeric pain rating scale-NPRS), fear-avoidance (fear avoidance beliefs questionnaire-FABQ), beliefs regarding aging and LBP (Likert scale) and active trunk flexion were measured.

RESULTS

Significant changes were found in positive shifts with LBP (p = 0.002), leg pain (p = 0.042), FABQ-physical activity subscale (p = 0.004) and active trunk forward flexion (p < 0.001).

DISCUSSION

The results show that education aimed at altering beliefs regarding LBP and aging result in a positive shift in pain, fear avoidance related to physical activity and active trunk flexion.

CONCLUSION

Prior to providing patients with new healthcare information, de-educating them regarding poor beliefs may be helpful in shifting them towards new, healthier paradigms associated with their condition.

Expectancies mediate the relationship between perceived injustice and return to work following whiplash injury: A 1-year prospective study

BACKGROUND

Emerging evidence suggests that perceived injustice is a risk factor for work disability in individuals with whiplash injury. At present, however, little is known about the processes by which perceived injustice impacts on return to work. The purpose of this study was to examine whether expectancies mediated the relationship between perceived injustice and return to work in patients with whiplash injury.

METHOD

One hundred and fifty-two individuals (81 men, 71 women) with a primary diagnosis of whiplash injury completed self-report measures of pain intensity, perceived injustice and return-to-work expectancies following admission to a rehabilitation programme. Work status was assessed 1 year after discharge.

RESULTS

Consistent with previous research, high scores on a measure of perceived injustice were associated with prolonged work disability. Results indicated that high perceptions of injustice were associated with low return-to-work expectancies. Causal mediation analyses revealed that expectancies fully mediated the relationship between perceived injustice and return to work.

CONCLUSION

The findings suggest that intervention techniques designed to target expectancies could improve return-to-work outcomes in patients with whiplash injury. Discussion addresses the processes by which expectancies might impact on return-to-work outcomes and the manner in which negative return-to-work expectancies might be modified through intervention.

SIGNIFICANCE

The study confirms that expectancies are the mechanism through which perceived injustice impacts return to work following whiplash injury. The findings suggest that interventions designed to specifically target return-to-work expectancies might improve rehabilitation outcomes in patients with whiplash injury.

Factors affecting planned return to work after trauma: A prospective descriptive qualitative and quantitative study

The use of patient reported outcome measures (PROMs) in trauma is limited. The aim of this pilot study is to evaluate qualitative responses and factors affecting planned return to work following significant trauma, for which there is currently a poor evidence base. National ethical approval was obtained for routine prospective PROMs data collection, including EQ-5D, between Sept 2013 and March 2015 for trauma patients admitted to the Sussex Major Trauma Centre (n=92). 84 trauma patients disclosed their intended return to work at discharge. Additional open questions asked 'things done well' and 'things to be improved'. EQ-5D responses were valued using the time trade-off method. Statistical analysis between multiple variables was completed by ANOVA, and with categorical categories by Chi squared analysis. Only 18/68 of patients working at admission anticipated returning to work within 14days post-discharge. The injury severity scores (ISS) of those predicting return to work within two weeks and those predicting return to work longer than two weeks were 14.17 and 13.59, respectively. Increased physicality of work showed a trend towards poorer return to work outcomes, although non-significant in Chi-squared test in groups predicting return in less than or greater than two weeks (4.621, p=0.2017ns). No significant difference was demonstrated in the comparative incomes of patients with different estimated return to work outcomes (ANOVA r²=0.001, P=0.9590ns). EQ-5D scores were higher in those predicting return to work within two weeks when compared to greater than two weeks. Qualitative thematic content analysis of open responses was possible for 66/92 of respondents. Prominent positive themes were: care, staff, professionalism, and communication. Prominent negative themes were: food, ward response time, and communication. This pilot study highlights the importance of qualitative PROMs analysis in leading patient-driven improvements in trauma care. We provide standard deviations for ISS scores and EQ-5D scores in our general trauma cohort, for use in sample size calculations for further studies analysing factors affecting return to work after trauma.

Expectancies as core features of mental disorders

PURPOSE OF REVIEW

Expectancies are core features of mental disorders, and change in expectations is therefore one of the core mechanisms of treatment in psychiatry. We aim to improve our understanding of expectancies by summarizing factors that contribute to their development, persistence, and modification. We pay particular attention to the issue of persistence of expectancies despite experiences that contradict them.

RECENT FINDINGS

Based on recent research findings, we propose a new model for expectation persistence and expectation change. When expectations are established, effects are evident in neural and other biological systems, for example, via anticipatory reactions, different biological reactions to expected versus unexpected stimuli, etc. Psychological 'immunization' and 'assimilation', implicit self-confirming processes, and stability of biological processes help us to better understand why expectancies persist even in the presence of expectation violations.

SUMMARY

Learning theory, attentional processes, social influences, and biological determinants contribute to the development, persistence, and modification of expectancies. Psychological interventions should focus on optimizing expectation violation to achieve optimal treatment outcome and to avoid treatment failures.

Initial healthcare and coping preferences are associated with outcome 1 year after whiplash trauma: a multicentre 1-year follow-up study

OBJECTIVE

Individuals exposed to whiplash collisions have to cope with the stressful event as well as early physical symptoms. As in other chronic pain conditions, coping has been associated with outcome after whiplash. In this study, our aim was to examine whether initial coping preferences were associated with the development of chronic whiplash.

DESIGN

Prospective study.

SETTING

Primary care.

METHODS

740 acute whiplash patients were recruited from emergency units and general practitioners after car collisions in Denmark. Within 10 days postinjury, participants were asked what they believed could help them get better. At 12-month follow-up, the level of neck pain and capability to work was obtained. Whether coping preferences (baseline) were associated with outcome was investigated using multiple regression analyses.

RESULTS

Persistent neck pain was most strongly associated with preferring medications (mean difference=1.24 (95% CI 0.67 to 1.82)) and sickness absence (mean difference=1.18 (95% CI 0.53 to 1.82)). Reduced work capability was most strongly associated with preferring medications (OR=3.53 (95% CI 2.13 to 5.86)), sickness absence (OR=3.05 (95% CI 1.80 to 5.17)) and being referred to a physiotherapist/chiropractor (OR=3.03 (95% CI 1.33 to 6.91)). Active coping was associated with better outcomes: Participants preferring to change their lifestyle were protected against reduced work capability (OR=0.11 (95% CI 0.01 to 0.78)). Individuals who wanted to keep living as usual only (no other preference reported) were protected against neck pain (mean difference -1.62 (95% CI -2.39 to -0.84)) and reduced work capability (OR=0.09 (95% CI 0.01 to 0.64)).

CONCLUSIONS

A simple nine-item measure of coping preferences is associated with the development of chronic neck pain and reduced capability to work following whiplash trauma and may be used to identify individuals at risk of poor recovery.
