Background Patient empowerment is growing in popularity and application. Due to the increasing possibilities of the Internet and eHealth, many initiatives that are aimed at empowering patients are delivered online. Objective Our objective was to evaluate whether Web-based interventions are effective in increasing patient empowerment compared with usual care or face-to-face interventions. Methods We performed a systematic review by searching the MEDLINE, EMBASE, and PsycINFO databases from January 1985 to January 2009 for relevant citations. From the 7096 unique citations retrieved from the search strategy, we included 14 randomized controlled trials (RCTs) that met all inclusion criteria. Pairs of review authors assessed the methodological quality of the obtained studies using the Downs and Black checklist. A meta-analysis was performed on studies that measured comparable outcomes. The GRADE approach was used to determine the level of evidence for each outcome. Results In comparison with usual care or no care, Web-based interventions had a significant positive effect on empowerment measured with the Diabetes Empowerment Scale (2 studies, standardized mean difference [SMD] = 0.61, 95% confidence interval [CI] 0.29 - 0.94]), on self-efficacy measured with disease-specific self-efficacy scales (9 studies, SMD = 0.23, 95% CI 0.12 - 0.33), and on mastery measured with the Pearlin Mastery Scale (1 study, mean difference [MD] = 2.95, 95% CI 1.66 - 4.24). No effects were found for self-efficacy measured with general self-efficacy scales (3 studies, SMD = 0.05, 95% CI -0.25 to 0.35) or for self-esteem measured with the Rosenberg Self-Esteem Scale (1 study, MD = -0.38, 95% CI -2.45 to 1.69). Furthermore, when comparing Web-based interventions with face-to-face deliveries of the same interventions, no significant (beneficial or harmful) effects were found for mastery (1 study, MD = 1.20, 95% CI -1.73 to 4.13) and self-esteem (1 study, MD = -0.10, 95% CI -0.45 to 0.25). Conclusions Web-based interventions showed positive effects on empowerment measured with the Diabetes Empowerment Scale, disease-specific self-efficacy scales and the Pearlin Mastery Scale. Because of the low quality of evidence we found, the results should be interpreted with caution. The clinical relevance of the findings can be questioned because the significant effects we found were, in general, small.

Do Compensation Processes Impair Mental Health? A Meta-Analysis

N.A. Elbers; Liesbeth Hulst; Pim Cuijpers; A.J. Akkermans; D.J. Bruinvels

BACKGROUNDnVictims who are involved in a compensation processes generally have more health complaints compared to victims who are not involved in a compensation process. Previous research regarding the effect of compensation processes has concentrated on the effect on physical health. This meta-analysis focuses on the effect of compensation processes on mental health.nnnMETHODnProspective cohort studies addressing compensation and mental health after traffic accidents, occupational accidents or medical errors were identified using PubMed, EMBASE, PsycInfo, CINAHL, and the Cochrane Library. Relevant studies published between January 1966 and 10 June 2011 were selected for inclusion.nnnRESULTSnTen studies were included. The first finding was that the compensation group already had higher mental health complaints at baseline compared to the non-compensation group (standardised mean difference (SMD)=-0.38; 95% confidence interval (CI) -0.66 to -0.10; p=.01). The second finding was that mental health between baseline and post measurement improved less in the compensation group compared to the non-compensation group (SMD=-0.35; 95% CI -0.70 to -0.01; p=.05). However, the quality of evidence was limited, mainly because of low quality study design and heterogeneity.nnnDISCUSSIONnBeing involved in a compensation process is associated with higher mental health complaints but three-quarters of the difference appeared to be already present at baseline. The findings of this study should be interpreted with caution because of the limited quality of evidence. The difference at baseline may be explained by a selection bias or more anger and blame about the accident in the compensation group. The difference between baseline and follow-up may be explained by secondary gain and secondary victimisation. Future research should involve assessment of exposure to compensation processes, should analyse and correct for baseline differences, and could examine the effect of time, compensation scheme design, and claim settlement on (mental) health.

BackgroundIt has been suggested that drug-paired stimuli (S+) control addictive behaviour by eliciting an explicit mental representation or expectation of drug availability.AimsThe aim of the present study was to test this hypothesis by determining whether the behavioural control exerted by a tobacco-paired S+ in human smokers would depend upon the S+ eliciting an explicit expectation of tobacco.DesignIn each trial, human smokers (n=16) were presented with stimuli for which attention was measured with an eyetracker. Participants then reported their cigarette reward expectancy before performing, or not, an instrumental tobacco-seeking response that was rewarded with cigarette gains if the S+ had been presented or punished with cigarette losses if the S− had been presented. Following training, participants rated the pleasantness of stimuli.ResultsThe S+ only brought about conditioned behaviour in an aware group (those who expected the cigarette reward outcome when presented with the S+). This aware group allocated attention to the S+, performed the instrumental tobacco-seeking response selectively in the presence of the S+ and rated the S+ as pleasant. No conditioned behaviour was seen in the unaware group (those who did not expect the cigarette reward outcome in the presence of the S+).ConclusionsDrug-paired stimuli control selective attention, instrumental drug-seeking behaviour and positive emotional state by eliciting an explicit expectation of drug availability.

Procedural Justice and Quality of Life in Compensation Processes

N.A. Elbers; A.J. Akkermans; Pim Cuijpers; D.J. Bruinvels

BACKGROUNDnThere is considerable evidence that being involved in compensation processes has a negative impact on claimants health. Previous studies suggested that this negative effect is caused by a stressful compensation process: claimants suffered from a lack of communication, a lack of information, and feelings of distrust. However, these rather qualitative findings have not been quantitatively investigated yet. This observational study aimed to fill this gap of knowledge, investigating the claimants perceived fairness of the compensation process, the provided information, and the interaction with lawyers and insurance companies, in relation to the claimants quality of life.nnnMETHODnParticipants were individuals injured in traffic accidents, older than 18 years, who were involved in a compensation process in the Netherlands. They were recruited by three claims settlement offices. Outcome measures were procedural, interactional, and informational justice, and quality of life.nnnRESULTSnParticipants (n=176) perceived the interaction with lawyers to be fairer than the interaction with insurance companies (p<.001). The length of hospital stay was positively associated with procedural justice (β=.31, p<.001). Having trunk/back injury was negatively related to procedural justice (β=-.25, p=.001). Whiplash injury and length of time involved in the claim process were not associated with any of the justice scales. Finally, procedural justice was found to be positively correlated with quality of life (rs=.22, p=.004).nnnDISCUSSIONnThe finding that the interaction with insurance companies was considered less fair than the interaction with lawyers may imply that insurers could improve their interaction with claimants, e.g. by communicating more directly. The result that claimants with mild injuries and with trunk/back injuries considered the compensation process to be less fair than those with respectively severe injuries and injuries to other body parts suggests that especially the former two require an attentive treatment. Finally, the fact that procedural justice was positively correlated with quality of life could implicate that it is possible to improve claimants health in compensation processes by enhancing procedural justice, e.g. by increasing the ability for claimants to express their views and feelings and by involving claimants in the decision-making process.

Differences in perceived fairness and health outcomes in two injury compensation systems: a comparative study

N.A. Elbers; Alex Collie; Sheilah Hogg-Johnson; Katherine Lippel; Keri Lockwood; Ian D. Cameron

BackgroundInvolvement in a compensation process following a motor vehicle collision is consistently associated with worse health status but the reasons underlying this are unclear. Some compensation systems are hypothesised to be more stressful than others. In particular, fault-based compensation systems are considered to be more adversarial than no-fault systems and associated with poorer recovery. This study compares the perceived fairness and recovery of claimants in the fault-based compensation system in New South Wales (NSW) to the no-fault system in Victoria, Australia.MethodsOne hundred eighty two participants were recruited via claims databases of the compensation system regulators in Victoria and NSW. Participants wereu2009>u200918xa0years old and involved in a transport injury compensation process. The crash occurred 12xa0months (nu2009=u200995) or 24xa0months ago (nu2009=u200987). Perceived fairness about the compensation process was measured by items derived from a validated organisational justice questionnaire. Health outcome was measured by the initial question of the Short Form Health Survey.ResultsIn Victoria, 84xa0% of the participants considered the claims process fair, compared to 46xa0% of NSW participants (χ2u2009=u200928.54; pu2009<u2009.001). Lawyer involvement and medical assessments were significantly associated with poorer perceived fairness. Overall perceived fairness was positively associated with health outcome after adjusting for demographic and injury variables (Adjusted Odds Ratiou2009=u20092.8, 95xa0% CIu2009=u20091.4 – 5.7, pu2009=u2009.004).ConclusionThe study shows large differences in perceived fairness between two different compensation systems and an association between fairness and health. These findings are politically important because compensation processes are designed to improve recovery. Lower perceived fairness in NSW may have been caused by potential adversarial aspects of the scheme, such as liability assessment, medical assessments, dealing with a third party for-profit insurance agency, or financial insecurity due to lump sum payments at settlement. This study should encourage an evidence informed discussion about how to reduce anti-therapeutic aspects in the compensation process in order to improve the injured person’s health.

Factors that challenge health for people involved in the compensation process following a motor vehicle crash: a longitudinal study

N.A. Elbers; A.J. Akkermans; Keri Lockwood; Ashley Craig; Ian D. Cameron

BackgroundMotor vehicle crashes (MVC) are associated with diminished mental health, and furthermore, evidence suggests the process of claiming compensation following an MVC further increases distress and impedes recovery. However, further research is required on why the compensation process is stressful. The aim of the current study is twofold. The first is to investigate whether the interaction with the insurance agency is associated with anxiety. The second is to explore qualitatively aspects of dissatisfaction with the compensation process.MethodsParticipants (N = 417) were injured people involved in a compensation scheme after a motor vehicle crash (MVC) in New South Wales, Australia. Interviews were conducted by phone at 2, 12 and 24 months after the MVC. A suite of measures were used including compensation related measures, pain catastrophising and the anxiety/depressed mood subscale of the EuroQol. The association between predictors and anxiety/depressed mood as the dependent variable were analysed using forward logistic regression analyses. The comments about dissatisfaction with the insurance company were analysed qualitatively.ResultsThe strongest predictor of mood status found was pain-related catastrophising, followed by dissatisfaction with the insurance company. Dissatisfaction was attributed to (1) lack of communication and lack of information, (2) delayed or denied payments of compensation, (3) slow treatment approval and discussions about causality, (4) too much complicated paperwork, and (5) discussions about who was at-fault.ConclusionsFactors were found that contribute to anxiety in the compensation process. The association between catastrophising and anxiety/depressive mood suggests it is worthwhile further investigating the role of negative cognitions in compensation processes. People who score highly on catastrophising after the MVC may benefit from early psychological interventions aiming at addressing negative cognitions. Another important stressor is the interaction with the insurance company. Stress is associated with problems of communication, medical treatment, and claim settlement. This study additionally draws attention to some under recognised problems such as delayed payments. Pro-active claims management could address some of the identified issues, which could improve health of injured people after a MVC.

Effectiveness of a web-based intervention for injured claimants: A randomized controlled trial

N.A. Elbers; A.J. Akkermans; Pim Cuijpers; D.J. Bruinvels

BackgroundThere is considerable evidence showing that injured people who are involved in a compensation process show poorer physical and mental recovery than those with similar injuries who are not involved in a compensation process. One explanation for this reduced recovery is that the legal process and the associated retraumatization are very stressful for the claimant. The aim of this study was to empower injured claimants in order to facilitate recovery.MethodsParticipants were recruited by three Dutch claims settlement offices. The participants had all been injured in a traffic crash and were involved in a compensation process. The study design was a randomized controlled trial. An intervention website was developed with (1) information about the compensation process, and (2) an evidence-based, therapist-assisted problem-solving course. The control website contained a few links to already existing websites. Outcome measures were empowerment, self-efficacy, health status (including depression, anxiety, and somatic symptoms), perceived fairness, ability to work, claims knowledge and extent of burden. The outcomes were self-reported through online questionnaires and were measured four times: at baseline, and at 3, 6, and 12xa0months.ResultsIn total, 176 participants completed the baseline questionnaire after which they were randomized into either the intervention group (nu2009=u200988) or the control group (nu2009=u200988). During the study, 35 participants (20%) dropped out. The intervention website was used by 55 participants (63%). The health outcomes of the intervention group were no different to those of the control group. However, the intervention group considered the received compensation to be fairer (P <0.01). The subgroup analysis of intervention users versus nonusers did not reveal significant results. The intervention website was evaluated positively.ConclusionsAlthough the web-based intervention was not used enough to improve the health of injured claimants in compensation processes, it increased the perceived fairness of the compensation amount.Trial registrationNetherlands Trial Register NTR2360

Exploring Lawyer-Client Interaction: A Qualitative Study of Positive Lawyer Characteristics

N.A. Elbers; Kiliaan A. P. C. van Wees; A.J. Akkermans; Pim Cuijpers; D.J. Bruinvels

Personal injury victims involved in compensation processes have a worse recovery than those not involved in compensation processes. One predictor for worse recovery is lawyer engagement. As some people argue that this negative relation between lawyer engagement and recovery may be explained by lawyers’ attitude and communications to clients, it seems important to investigate lawyer–client interaction. Although procedural justice and therapeutic jurisprudence had previously discussed aspects relevant for lawyer–client interaction, the client’s perspective has been rather ignored and only few empirical studies have been conducted. In this qualitative study, 21 traffic accident victims were interviewed about their experiences with their lawyer. Five desirable characteristics for lawyers were identified: communication, empathy, decisiveness, independence, and expertise. Communication and empathy corresponded with aspects already discussed in literature, whereas decisiveness, independence and expertise had been addressed only marginally. Further qualitative and quantitative research is necessary to establish preferable lawyer characteristics and to investigate what would improve the well-being of personal injury victims during the claims settlement process.

Do claim factors predict health care utilization after transport accidents

N.A. Elbers; Pim Cuijpers; A.J. Akkermans; Alex Collie; Rasa Ruseckaite; D.J. Bruinvels

BACKGROUNDnInjured people who are involved in compensation processes have less recovery and less well-being compared to those not involved in claims settlement procedures. This study investigated whether claim factors, such as no-fault versus common law claims, the number of independent medical assessments, and legal disputes, predict health care utilization after transport accidents.nnnMETHODnThe sample consisted of 68,911 claimants who lodged a compensation claim at the Transport Accident Commission (TAC) in Victoria, Australia, between 2000 and 2005. The main outcome measure was health care utilization, which was defined as the number of visits to health care providers (e.g. general practitioners, physiotherapists, psychologists) during the 5 year period post-accident.nnnRESULTSnAfter correction for gender, age, role in accident, injury type, and severity of injury, it was found that independent medical assessments were associated with greater health care utilization (β=.36, p<.001). Involvement in common law claims and legal disputes were both significantly related to health care utilization (respectively β=.05, p<.001 and β=-.02, p<.001), however, the standardized betas were negligible, therefore the effect is not clinically relevant. A model including claim factors predicted the number of health care visits significantly better (ΔR(2)=.08, p<.001) than a model including only gender, age, role in accident, injury type, and severity of injury.nnnCONCLUSIONnThe positive association between the number of independent medical assessments and health care utilization after transport accidents may imply that numerous medical assessments have a negative effect on claimants health. However, further research is needed to determine a causal relationship.

Empowerment of personal injury victims through the internet: design of a randomized controlled trial

N.A. Elbers; A.J. Akkermans; Pim Cuijpers; D.J. Bruinvels

BackgroundResearch has shown that current claims settlement process can have a negative impact on psychological and physical recovery of personal injury (PI) victims. One of the explanations for the negative impact on health is that the claims settlement process is a stressful experience and victims suffer from renewed victimization caused by the claims settlement process. PI victims can experience a lack of information, lack of involvement, lack of voice, and poor communication. We present the first study that aims to empower PI victims with respect to the negative impact of the claims settlement process by means of an internet intervention.Methods/designThe study is a two armed, randomized controlled trial (RCT), in which 170 PI victims are randomized to either the intervention or control group. The intervention group will get access to a website providing 1) an information module, so participants learn what is happening and what to expect during the claims settlement process, and 2) an e-coach module, so participants learn to cope with problems they experience during the claims settlement process. The control group will get access to a website with hyperlinks to commonly available information only. Participants will be recruited via a PI claims settlement office. Participants are included if they have been involved in a traffic accident which happened less than two years ago, and are at least 18 years old.The main study parameter is the increase of empowerment within the intervention group compared to the control group. Empowerment will be measured by the mastery scale and a self-efficacy scale. The secondary outcomes are perceived justice, burden, well being, work ability, knowledge, amount of damages, and lawyer-client communication. Data are collected at baseline (T0 measurement before randomization), at three months, six months, and twelve months after baseline. Analyses will be conducted according to the intention-to-treat principle.DiscussionThis study evaluates the effectiveness of an internet intervention aimed at empowerment of PI victims. The results will give more insight into the impact of compensation proceedings on health over time, and they can have important consequences for legal claims settlement. Strengths and limitations of this study are discussed.Trial registrationNetherlands Trial Register NTR2360
