RESUMO
PURPOSE: The construct validity of functional capacity evaluations (FCE) in whiplash-associated disorders (WAD) is unknown. The aim of this study was to analyse the validity of FCE in patients with WAD with cultural differences within a workers' compensation setting. METHODS: 314 participants (42% females, mean age 36.7 years) with WAD (grade I and II) were referred for an interdisciplinary assessment that included FCE tests. Four FCE tests (hand grip strength, lifting waist to overhead, overhead working, and repetitive reaching) and a number of concurrent variables such as self-reported pain, capacity, disability, and psychological distress were measured. To test construct validity, 29 a priori formulated hypotheses were tested, 4 related to gender differences, 20 related associations with other constructs, 5 related to cultural differences. RESULTS: Men had significantly more hand grip strength (+17.5 kg) and lifted more weight (+3.7 kg): two out of four gender-related hypotheses were confirmed. Correlation between FCE and pain ranged from -0.39 to 0.31; FCE and self-reported capacity from -0.42 to 0.61; FCE and disability from -0.45 to 0.34; FCE and anxiety from -0.36 to 0.27; and FCE and depression from -0.41 to 0.34: 16 of 20 hypotheses regarding FCE and other constructs were confirmed. FCE test results between the cultural groups differed significantly (4 hypotheses confirmed) and effect size (ES) between correlations were small (1 hypothesis confirmed). In total 23 out of 29 hypotheses were confirmed (79%). CONCLUSIONS: The construct validity for testing functional capacity was confirmed for the majority of FCE tests in patients with WAD with cultural differences and in a workers' compensation setting. Additional validation studies in other settings are needed for verification.

BACKGROUND: The Australian Whiplash Disability Questionnaire (WDQ) was cross-culturally translated, adapted, and tested for validity to be used in German-speaking patients. The self-administered questionnaire evaluates actual pain intensity, problems in personal care, role performance, sleep disturbances, tiredness, social and leisure activities, emotional and concentration impairments with 13 questions rated on an 11-point rating scale from zero to ten. METHODS: In a first part, the Australian-based WDQ was forward and backward translated. In a consensus conference with all translators and health care professionals, who were experts in the treatment of patients with a whiplash associated disorder (WAD), formulations were refined. Original authors were contacted for clarification and approval of the forward-backward translated version. The German version (WDQ-G) was evaluated for comprehensiveness and clarity in a pre-study patient survey by a random sample of German-speaking patients after WAD and four healthy twelve to thirteen year old teenagers. In a second part, the WDQ-G was evaluated in a patient validation study including patients affected by a WAD. Inpatients had to complete the WDQ-G, the North American Spine Society questionnaire (NASS cervical pain), and the Medical Outcomes Study 36-Item Short Form Health Survey (SF-36) at entry in the rehabilitation centre. RESULTS: In the pre-study patient survey (response rate 31%) patients rated clarity for title 9.6 ± 0.9, instruction 9.3 ± 1.4 and questions 9.6 ± 0.7, and comprehensiveness for title 9.6 ± 0.7, instruction 9.3 ± 1.4 and questions 9.8 ± 0.4. Time needed to fill in was 13.7 ± 9.0 minutes. In total, 70 patients (47 females, age = 43.4 ± 12.5 years, time since injury: 1.5 ± 2.6 years) were included in the validation study. WDQ-G total score was 74.0 ± 21.3 points (range between 15 and 117 points). Time needed to fill in was 6.7 ± 3.4 minutes with data from 22 patients. Internal consistency was confirmed with Cronbachs's α = 0.89. Concurrent validity showed a highly significant correlation with subscale pain and disability (NASS) at r = 0.74 and subscale pain (SF-36) at r = 0.71. CONCLUSIONS: The officially translated and adapted WDQ-G can be used in German-speaking patients affected by a WAD to evaluate patients' impairments in different domains. The WDQ-G is a self-administered outcome measure showing a high internal consistency and good concurrent validity.

BACKGROUND: Beliefs and expectations are thought to influence outcome following whiplash injury. Studies have proposed a link between rates of chronic whiplash and laypersons' expectations about outcome following a motor vehicle accident. The prevalence of chronic whiplash is relatively high in Australia and apparently low in Singapore. This study's objectives were to compare laypersons' beliefs and expectations of recovery of whiplash injury in Brisbane and Singapore and to assess the effect of demographic factors on whiplash beliefs. METHODS: A cross-sectional study using online surveys was conducted on adult Internet users in Brisbane (Australia) and Singapore. The 14-item whiplash beliefs questionnaire (WBQ) was used to evaluate whiplash beliefs. Two additional items assessed expectations of recovery. Individual items of WBQ, WBQ score and expectations of recovery were analysed. Stratified analysis was performed to adjust for sampling bias due to quota sampling. RESULTS: A total of 402 participants from Singapore and 411 participants from Brisbane, Australia, completed the survey. While participants from Singapore demonstrated slightly more negative whiplash beliefs than participants from Brisbane [t(811) = -5.72; p < 0.0001], participants from both samples were similar in their expectations of quick recovery and return to normal activities following whiplash injury. Only gender had a significant effect on whiplash beliefs [estimated marginal means of WBQ score for men = 21.5; standard error (SE) = 0.20; women = 22.5; SE = 0.20; F(1,810) = 11.2; p = 0.001]. CONCLUSIONS: Laypersons' expectations of recovery and beliefs about whiplash injury in Brisbane and Singapore were generally similar and mostly positive. Our results demonstrate that cultural differences reflected by laypersons' beliefs may not reflect the differences in prevalence of chronic whiplash between countries.

OBJECTIVE: Symptom expectation for whiplash injury has been shown to be low in countries with low rates of chronic whiplash when compared with countries like Canada, where chronic whiplash is common. The objective of the current study is to compare the frequency and nature of expected "whiplash" symptoms in Germany with that in Canada. METHODS: A symptom checklist was administered to two subject groups selected from local companies in Germany and Canada. Subjects were asked to imagine having suffered a neck sprain (whiplash injury) with no loss of consciousness in a motor vehicle collision and to check which, of a variety of symptoms, they would expect might arise from the injury. For symptoms they anticipated, they were asked to select the period of time they expected those symptoms to persist. RESULTS: In both groups, the pattern of acute symptoms anticipated closely resembled the symptoms of acute whiplash victims, but 50% of Canadians also anticipated symptoms to last months or years, whereas few German subjects selected any symptoms as likely to persist. CONCLUSIONS: In Germany, despite the documented occurrence of neck sprain symptoms in individuals following motor vehicle collisions, there is a very low rate of expectation of any sequelae from this injury. The current or previous aspects of society that underlie this remain uncertain. This lack of expectation of chronicity in Germany may, in part, determine the low prevalence of the chronic whiplash syndrome there. Further studies of symptom expectation as an etiologic factor in the chronic whiplash syndrome are needed.

This paper gives a detailed account of 30 cases of childhood deaths caused by physical abuse, detected by the Suspected Child Abuse and Neglect (SCAN) team, General Hospital, Kuala Lumpur. They consisted of 12 Malays, 6 Chinese, 9 Indian, and 1 Indonesian child. Three cases could not be ascertained as to their ethnic origin. There were 13 male and 17 female children. The average age of the abused children was 2 years 5 months. The most frequent causes of death were intracranial hemorrhage and intraabdominal trauma. Of the 17 cases of intracranial hemorrhage, only four had X-ray evidence of skull fracture. This suggests the possibility of whiplash injuries with/without the abuser suspecting that he/she had injured the child. Of the 22 abusers who could be identified, there was no sex differentiation. Fathers formed the largest group of perpetrators, followed by mothers and childminders. Fifteen of the natural parents of the abused children were married, four were divorced and four were never married. Five of the abusers had aggressive personalities and three were drug addicts. Only one abuser was found to be an alcoholic even though a few were also under suspicion. For most cases, trigger factors could not be identified.
