Reliability and validity of The Awareness of Social Inference Test (TASIT): A clinical test of social perception

Purpose.?The Awareness of Social Inference Test (TASIT) is an audiovisual tool designed for the clinical assessment of social perception with alternate forms for re-testing. Part 1 assesses emotion recognition, Parts 2 and 3 assess the ability to interpret conversational remarks meant literally (i.e., sincere remarks and lies) or non-literally (i.e., sarcasm) as well as the ability to make judgments about the thoughts, intentions and feelings of speakers. This paper aims to examine TASIT's reliability and validity.

Method.?Some 32 adults with severe, chronic brain injuries were administered Form A twice, one week apart. 38 adults with brain injuries were readministered alternate forms over a period of 5 – 26 weeks. Construct validity was examined in subsets of a sample of 116 adults with brain injuries by relating TASIT performance to standard tests of neuropsychological function and specific social perception measures.

Results.?Test-retest reliability ranged from 0.74 – 0.88. Alternate forms reliability ranged from 0.62 – 0.83. TASIT performance was associated with face perception, information processing speed and working memory. Socially relevant new learning and executive tasks were significantly associated with TASIT performance whereas non-social tasks showed little association. Social perception tasks such as Ekman photos and theory of mind stories were also associated.

Conclusions.?TASIT has adequate psychometric properties as a clinical test of social perception. It is not overly prone to practice effects and is reliable for repeat administrations. Performance on TASIT is affected by information processing speed, working memory, new learning and executive functioning, but the uniquely social material that comprises the stimuli for TASIT will provide useful insights into the particular difficulties people with clinical conditions experience when interpreting complex social phenomena.     

REPAS, a summary rating scale for resistance to passive movement: item selection, reliability and validity

Purpose. To establish: (i) item characteristics and item selection for the REPAS; (ii) internal consistency, inter-rater and test-retest reliability of the final REPAS version and its subtests; (iii) the association between the REPAS and selected other clinical scales of impairment and activity limitation.

Method. Thirty-three neurological patients with central paresis. Two REPAS assessments with a one-week interval by two independent raters. Concurrent assessment of the Motricity Index, Box-and-Block test, Functional Ambulation Category, Timed walking, Barthel Index, Disability Rating Scale, Carer Burden Scale, and Hygiene Score.

Results. Twenty-six of 52 REPAS items fulfilled the item selection criteria. The final test version showed a high internal consistency, inter-rater and test-retest reliability (correlation coefficients: 0.87 - 0.97, no significant difference between raters or with test repetition). Reliability of the arm and leg subtests was substantial (correlation coefficients: arm subtest 0.63 - 0.98, leg subtest 0.56 - 0.96). REPAS scores were moderately associated with basic ADL competence and a carer's burden with arm or leg adductor spasticity. The REPAS, arm subtest scores, degree of arm paresis and gross manual dexterity showed a moderately high association.

Conclusions. The Ashworth scale-based guidelines assured comparability of test administration and scoring. The REPAS is a reliable and valid summary rating scale for resistance to passive movement.     

The social experience of aging with a chronic illness: perspectives of older adults with multiple sclerosis

Purpose. The purpose of this study was to explore the social experiences of older adults with multiple sclerosis (MS) in order to recognize the changes in social experience and social needs that may occur with aging with a chronic illness.

Method. Analysis of qualitative data from an exploratory study utilizing a phenomenological approach with 27 older adults with MS, aged 55 - 81.

Results. In-depth interviews revealed that the social experience was influenced by groups of factors including the person's social needs, experience of MS, values and expectations, characteristics of the social support system, the response of the support providers, and the accessibility of the social environment. The participants discussed concerns about the future adequacy of support. A process of negotiation was also described and was seen as an opportunity to change the social experience and social support received.

Conclusion. This study provides an insider's view of the social changes that older adults living with MS experience. This study also identifies barriers to the acquisition of support and addresses the importance of appropriately responding to the changing needs of this population.     

Can children with developmental coordination disorder adapt to task constraints when catching two-handed?

Purpose. To compare the nature and extent of inter and intralimb coupling during two-handed catching and the effect of manipulating task constraints in children with Developmental Coordination Disorder (DCD) and their typically developing peers (AMC).

Method. Twenty children aged 7 - 10 years, ten with DCD and 10 AMC attempted to catch a ball ten times in condition 1 (C1), ball to the midline; condition 2 (C2), ball to the left shoulder and condition 3 (C3), ball to the right shoulder. Both 3D kinematic data and video data were collected.

Results. Children with DCD caught fewer balls than the AMC children, regardless of age or condition (p ≤ 0.001). Children with DCD demonstrated a higher degree of linkage between limbs in C1 and a lower degree of between limb coupling in C2 and C3 when compared to the AMC (p ≤ 0.05). Differences between the AMC7 - 8 and AMC9 - 10 group were found with respect to interlimb coupling.

Conclusions. The influence of manipulating task constraints and the individual nature of children with DCD must be considered by those involved in rehabilitation. By doing so, children with DCD may search for appropriate motor solutions to many functional movement tasks required for everyday life.     

Reduced community integration in persons following traumatic brain injury, as measured on the Community Integration Measure: an exploratory analysis

Purpose. To explore the community integration of individuals who had suffered a Traumatic Brain Injury (TBI) and compare this to members of the general public.

Method. An independent groups design explored differences in three groups' levels of community integration. These groups consisted of ten survivors of TBI, ten male and ten female controls and were measured using The Community Integration Measure (CIM). All participants were resident in Northern Ireland (NI). The brain injured participants were drawn from a Belfast-based social skills programme.

Results. Mann-Whitney U tests showed a statistically significant difference between female controls and brain-injured individuals (U = 26.50, N₁ = 10, N₂ = 10, p = 0.037, one-tailed).

Conclusion. Females were more integrated into their communities than males, who were, in turn, more integrated than brain injured individuals. It would appear that brain injury survivors are doubly disadvantaged. Their gender (mainly male), and the injury itself, conspire to reduce their integration within the wider community.     

Young women with fibromyalgia in the United States and Sweden: perceived difficulties during the first year after diagnosis

Purpose. The major symptoms of fibromyalgia (FM) - pain, tiredness, disrupted sleep, and muscle weakness - severely impact everyday activities, including the paid work role of women who have had FM for a long time. There are no prospective studies on young and newly diagnosed women with FM. The aim of the present study was to describe and compare difficulties young and newly diagnosed women in Sweden and the United States experienced during their first year after diagnosis.

Method. Three interviews, 6 months apart, were conducted, with 49 Swedish and 45 US women between the ages of 18 and 39. Five open-ended questions were asked concerning physical, psychological and social difficulties and limitations, and factors that increased or decreased their difficulties and limitations. At interviews 2 and 3 the women were also asked about ways of preventing their difficulties. The answers were written down and analysed by a content analysis approach.

Results. Consistent categories of difficulties were reported: symptoms, movements, activities, moods, social network, external factors and coping strategies. More US women were working outside their homes than were their Swedish counterparts and they expressed more difficulties compared with the Swedish women.

Conclusions. In general, difficulties decreased and coping strategies increased over the 1-year period in both groups of newly diagnosed, young women.     

Determinants of functioning of adolescents and young adults with cerebral palsy

Purpose. To describe the level of functioning of adolescents and young adults with cerebral palsy (CP) and study determinants of their level of functioning.

Method. In the CP Transition study, adolescents and young adults aged 16 - 20 years, diagnosed with CP without severe learning disabilities (n = 103) participated. In this group we assessed subject characteristics, i.e., age, type of CP, gross motor function (GMFCS), level of education as well as outcome measures on functioning in daily activities and social participation (Life Habits questionnaire, Vineland Adaptive Behavior Scale, Functional Independence Measure). Multivariate regression analyses were performed.

Results. About 20 - 30% of the participants encountered restrictions in daily activities (mobility, self-care, nutrition) and social participation (taking responsibility, community living, leisure activities and employment). The GMFCS level, level of education, and age proved to be important determinants of functioning in daily activities and social participation, explaining 70% and 66% of the variance in outcome respectively.

Conclusion. A significant number of adolescents and young adults with CP without severe learning disabilities are restricted in daily activities and social participation. These problems are mainly attributable to restricted gross motor functioning, a low level of education and younger age.     

Prevalence and impact of disability in north-western Ethiopia

Purpose. To assess the prevalence and impact of disability in one urban and three rural areas in north-western Ethiopia.

Methods. The study design is cross-sectional and quantitative. Data was collected by using pretested and standardized structured questionnaires containing socio-demographic characteristics, type of disability, functional, and social dysfunction.

Results. A total of 932 individuals with disability were found out of a total of 24,453 individuals giving the overall crude disability rate for the three towns as 3.8%. Disability in the lower locomotor was the most frequently reported type - 442 (47.0%) - followed by blindness 269 (28.6%), upper motor 152 (16.1%), mental retardation 97 (10.3%) and hearing loss 78 (8.3%) respectively. The major self-care problem experienced by the disabled is toileting in 292 (31.1%) cases, bathing in 248 (26.4%) and dressing 157 (16.7%). Other problems experienced by the respondents are parents' negative attitudes towards the disabled, evidenced by hiding them. This was observed in 340 (36.2%) cases. No care was provided by caregivers in 221 (23.6%) cases.

Conclusion. The majority of disabled people have problems with activities of daily life especially toileting, bathing and dressing. Interventions to alleviate the problems of the disabled should be designed and implemented.     

Adapting the Canadian Occupational Performance Measure for use in a paediatric clinical trial

Background. The Canadian Occupational Performance Measure (COPM) is a commonly used outcome measure in rehabilitation. In this study it was adapted for very young children by deleting paid/unpaid work and household management categories and having parents act as proxies to rate child performance and their own satisfaction.

Purpose. To assess the internal consistency reliability, content and construct validity, responsiveness, and impact of half scores (20 not 10-point scale) of the adapted COPM.

Method. Parent proxies of subjects aged 2 - 8 (mean 3.9) years with spastic hemiplegic cerebral palsy (n = 41) participating in a clinical trial. There was a total of 214 occupational performance problems for analysis and an additional 56 which had used half score ratings. Internal consistency reliability and construct validity were evaluated using Cronbach alpha statistic. Proxy views explored content validity. Responsiveness was evaluated using pre-post intervention scores and a comparison with Goal Attainment Scaling scores which were assumed to be a suitable benchmark measure. The effect of half scores was assessed by two-sample t-tests.

Results. The COPM adaptations did not have a negative impact on internal consistency reliability as this was acceptable for performance (0.73) and satisfaction (0.83). The high Cronbach alpha scores indicated good construct validity. Content of occupations and rating approach was considered valid by proxies. Use of half scores did not result in significantly different performance ratings, but mean satisfaction ratings were significantly higher when half scores were used (p = 0.0001). This suggests that half scores may provide more precise proxy satisfaction ratings, but at the cost of rigour as internal consistency with satisfaction half scores was lower (0.63 vs. 0.82). Responsiveness to change in clinical status was demonstrated by significant pre-post scores and moderate correlations with goal attainment scores.

Conclusion. The adapted COPM is a psychometrically robust tool and the use of half scores is not recommended.     

Can the results 6 months after anterior cervical decompression and fusion identify patients who will have remaining deficit at long-term?

Purpose. There is no knowledge if short-term outcome in patients after anterior cervical decompression and fusion (ACDF) can be used to identify which patients have remaining deficit in long term. This study investigates if 6-month outcome with a broad assessment after ACDF with a cervical intervertebral fusion cage can be a guide for the 3-years outcome.

Method. A prospective study. Questions about background data, pain, numbness, neck specific disability, distress, sick leave, health, symptom satisfaction and effect of and satisfaction with surgery were asked 28 patients 3 years after ACDF. Measurements have earlier been obtained before and 6 and 12 months after ACDF.

Results. Compared with the results before surgery patients had improved in pain intensity (p = 0.001), neck pain (0.001), numbness (p = 0.02) and were more 'satisfied' with having their neck problems (p = 0.01). Except for a worsening in expectations of surgery fulfilled (p = 0.04) there were no significant differences between 6-month and 3-year outcome. Three years after ACDF about two-thirds of the patients had remaining deficit with regard to pain intensity, Neck Disability Index, Distress and Risk Assessment Method and general health. According to the parameters studied 50 - 78% of those who at the 6-month follow-up were without deficit were still healthy at the 3-year follow-up. For patients with deficit at 6-month follow-up, still 83 - 100% had deficit 3 years after surgery.

Conclusions. Despite a rather small study obtained the stability of 6-month and 3-year results indicates that short-term results might be sufficient for evaluating effects of the treatment. Since the patients in this study clearly demonstrate broad problems array of development of more structured multi-professional rehabilitation models including exercises which improve neck muscle strength, endurance and proprioception need to be introduced.     

Prediction of long-term occupational performance outcomes for adults after moderate to severe traumatic brain injury

Purpose. To examine predictors of long-term occupational performance outcomes for adults after moderate to severe traumatic brain injury (TBI).

Method. This study involved analysis of data from a retrospective cohort of adults (N = 306) with moderate to severe TBI discharged from a Pennsylvania rehabilitation treatment facility. Extensive pre-injury sociodemographic, injury-severity, post-injury personal (cognitive, physical, affective), post-injury environmental (social, institutional, physical), and post-injury occupational performance (participation in self-care, productivity, leisure activities) data were gathered from hospital records and using in-person interviews. Interviews occurred at a mean time of 14 (range, 7-24) years post-injury. Hierarchical multiple regression analysis was used to investigate determinants of long-term occupational performance outcomes.

Results. Pre-injury behavioural problems, male gender, post-injury cognitive and physical deficits, and lack of access to transportation were significant independent predictors of worse occupational performance outcomes.

Conclusions. The study supports the use of a comprehensive model for long-term outcomes after TBI where pre-injury characteristics and post-injury cognitive and physical characteristics account for the greatest proportion of explained variance.     

Young people's experiences using electric powered indoor - outdoor wheelchairs (EPIOCs): potential for enhancing users' development?

Purpose. To examine the experiences of severely physically disabled young people who use electric powered indoor - outdoor chairs (EPIOCs).

Methods. A priori interview questions examined young people's functioning with EPIOCs, pain and discomfort with EPIOC use and accidents or injuries resulting from EPIOC use. Eighteen young people (13 males and five females) aged 10 - 18 (mean 15) years were interviewed by telephone using a qualitative framework approach. Participants were interviewed 10 - 19 (mean 14.5) months after delivery of the chair. Diagnoses included muscular dystrophy (n = 10), cerebral palsy (n = 5), and 'other' (n = 3).

Results. Many children reported positive functioning following EPIOC use, including increased independence and social activities like wheelchair football. However, EPIOC use was also associated with pain and discomfort, as well as perceived lack of safety, and minor accidents. Most young people and their families were fairly satisfied with the service and provision of their wheelchairs.

Conclusions. The findings suggest that the development of disabled young people may benefit from the use of electric powered indoor/outdoor wheelchairs, although the advantages may come at certain costs to young people's perceived and real safety. Recommendations to powered wheelchair providers include the demonstrated need for additional driving training as these young people mature.     

Inter-limb coordination in bimanual reach-to-grasp following stroke

Purpose. To determine the extent to which inter-limb coordination in the execution of unimanual and bimanual tasks was impaired following stroke.

Methods. Thirteen stroke survivors aged 55 - 77 years and 13 healthy, neurologically intact participants aged 57 - 86 years performed a unimanual and two bimanual tasks involving the relocation of single and paired objects. Movements were recorded using electromagnetic sensors attached to the wrists and a series of micro switches placed under the objects. Main outcome measures included time to complete components of the tasks; comparison between sides; deviation of the hands from a linear trajectory; coordination of the two sides as indicated by relative phase angle.

Results. Stroke survivors took longer to complete the bimanual tasks, but did not deviate from the optimal trajectories more than the healthy participants. Both groups performed unimanual tasks faster than bimanual and stroke participants were only slightly less synchronised when performing bimanual tasks.

Conclusions. In conclusion, in a group of stroke patients with reasonable strength, inter-limb coordination was mildly impaired. This impairment in coordination was not due to lateral deviation of the impaired limb.     

Perceptual-motor coordination in persons with mild intellectual disability

Background. There is limited experimental evidence to support the view that individuals with intellectual disabilities (ID) have a deficit in motor control. This work is a first attempt to evaluate their motor coordination.

Purpose. The study assessed the relationship between cognitive ability and sensorimotor integration. The clinical hypothesis is that adults with ID fall below non-ID adults in motor skills that involve hand-eye coordination.

Method. A group of 42 adults with ID (ID group) was compared to 48 age-matched typical adults (TA) using a mixed experimental design ('Task' as the within-subjects factor and 'Group' as the between-subjects factor). Participants performed the following tests twice: Box-and-Blocks, 25-Grooved-Pegboard, Stick Catching and overhead Beanbag-Throw. Pearson correlations and ANOVAs were used to test the hypothesis (p ≤ 0.05).

Results. As expected, TA outperformed the ID group in all tests regardless of the hand used during for the assessment. However, TA individuals scored significantly better with one hand (i.e., the preferred and dominant hand) as opposed to persons with ID, who exhibited no hand preference. Test-retest correlations among the first and second assessment scores yielded moderate-strong coefficients, depending on the type of test (Box-and-Blocks = 0.92 and 0.96, 25-Grooved-Pegboard = 0.69 and 0.83, Stick-Catching = 0.88 and 0.94, Beanbag-Throw = 0.58 and 0.91 for ID and TA, respectively).

Discussion. Difficulties in the integration of perceptual information into motor action may result in inadequate solutions to daily motor problems. As it stems from our results, intellectual disability relates to inability to integrate visual inputs and hand movements. In people with mild ID such inability is observed using both hands (i.e., they show no hand preferences). Poor perceptual-motor coordination might have a functional significance in that it may lead to exclusion from vocational and recreational activities, and a decreasing competence of ADL. Assessing coordination in adults with ID may contribute to understanding the nature of the ID condition and may encourage an early rehabilitation.     

Public health significance of the frailty index

Background. A quantifiable indicator of frailty would be very useful in assessing the health state of older populations, as well as enable the effect of interventions to be evaluated over time.

Methods. A total of 2032 people aged 70 years and over recruited by stratified random sampling, and information obtained regarding physical and functional health, and psychological factors. The frailty index (FI) was constructed from 62 variables. Associations between the FI, and changes in ADL score, mental score, and hospitalization days over a 10-year period were evaluated.

Results. For the baseline to 3-year changes, a 0.10 increase in baseline FI is accompanied by a 0.499-point faster drop in ADL score, a 0.223-point faster decline in mental score, and 4.57-day faster increase in hospital days. For 3 - 10-year changes, frailty was a significant predictor only of changes in mental score, with results indicating that, on average, each increase of 0.10 in the baseline frailty index was associated with 0.613-point drop in mental score during this period. Chronological age and frailty had differential associations with those changes.

Conclusion. The FI is a valid indicator of morbidity and requirement for health and social services for ageing populations.     

Are localized low back pain and generalized back pain similar entities? Results of a longitudinal community based study

Purpose. To compare subjects with localized low back pain (LBP) and with generalized back pain (BP) with regard to baseline characteristics and long-term outcomes.

Methods. A community-based longitudinal study. All inhabitants aged 22 - 70 of a single town were asked to complete self-administered questionnaires regarding back and neck pain and lifestyle characteristics. Those reporting LBP during the previous month were followed up after one year. Data were stratified by sites of pain with respect to 'localized LBP' and to 'LBP with additional sites of BP'. Among LBP measures were the Roland and Morris Disability scale and Pain symptoms indices.

Results. Nearly 30% of the total population (602) experienced LBP during the previous month, of whom more than half (336) reported 'localized LBP' and the rest LBP + neck and or upper back pain (Generalized BP). Both subgroups differed from those free of BP, however, those reported 'Generalized BP' comprised more females, were less educated, smoked more, were less engaged in sporting activities and reported higher level of LBP measures than those reported 'localized LBP'. After one year, both subgroups were similar with regard to lifestyle but remained different with regard to some of the LBP measures.

Conclusions. Subjects with 'localized LBP' presented healthier lifestyle than subjects with 'Generalized BP'. The latter experienced higher degree of pain measures. It seems that 'Generalized BP' is not a different entity than 'localized LBP' but rather a more severe one.     

Prophylaxis of venous thromboembolism during early inpatient rehabilitation after acquired brain injury: how guidelines change management

Purpose. To establish guidelines for prophylaxis of venous thromboembolism (VTE) in younger adults undergoing early inpatient rehabilitation following acquired brain injury (ABI).

Method. A two-phase (phase 1: retrospective; phase 2: prospective) observational study was carried out involving patients admitted to an inpatient neurological rehabilitation unit during a 40-month period. In phase 1, VTE prophylaxis was prescribed on an ad hoc basis. In phase 2, prophylaxis was considered in accordance with guidelines agreed locally. The prescribing behaviour in each phase of the study was compared using a VTE risk stratification tool based on expert opinion and a review of the literature.

Results. Data were obtained on 94 patients in phase 1 and 23 patients in phase 2. During phase 1, the prophylactic prescribing behaviour of the referring hospitals and our unit after admission were similar ( p = 0.13). In phase 2, our prescribing behaviour had changed compared with that of the referring hospitals, with a significant increase in the proportion of patients on appropriate treatment ( p = 0.01) and a decrease in the numbers under-treated ( p = 0.002). We were also significantly less likely to under-treat ( p = 0.005) and more likely to over-treat ( p = 0.004) after admission during phase 2 compared with phase 1, whilst practice was variable in patients at moderate risk.

Conclusions. Guidelines modify behaviour. They must stratify risk, particularly to avoid inconsistencies in the management of patients at moderate risk. There is a need to establish national guidelines for VTE prophylaxis during early inpatient rehabilitation after ABI; these guidelines should include a risk stratification tool.     

Cognitive functioning of adolescents and young adults with meningomyelocele and level of everyday physical activity

Purpose. To explore whether cognitive functioning in patients with meningomyelocele (MMC) is related to level of everyday physical activity.

Method. In a cross-sectional study in 14 patients with MMC (aged 14 - 26 years) a neuropsychological test battery was administered to each patient. Everyday physical activity of the patients was measured with an accelerometry-based Activity Monitor (AM), and compared to 14 healthy comparison subjects.

Results. Intellectual ability of 10 patients was in the normal range. For memory and verbal learning, executive functioning, divided attention and reaction speed subnormal scores were present in six or more patients. Time spent on dynamic activities was low in patients with MMC as compared to healthy subjects. After controlling for intellectual ability, we found that in patients with MMC (i) executive functioning was positively related, and (ii) word production was negatively related to everyday physical activity.

Conclusion. We found some indication that specific impairments in executive functioning might be related to everyday physical activity of adolescents and young adults with MMC.     

A pilot study of a web-based physical activity motivational program for adults with physical disabilities

Purpose. Develop, deliver, and assess the efficacy of a 4-week web-based leisure-time physical activity (LTPA) motivational program based on the Transtheoretical Model and tailored to inactive adults with physical disabilities.

Method. This was a pilot-based study incorporating a true experimental design with one treatment and one control group. The intervention program was delivered on the web and was based on the constructs of the Transtheoretical Model. From the 151 individuals who completed the LTPA standardized questionnaire at baseline, 75 people participated in the 1-month post-test assessment.

Results. The results of the analysis confirmed the pretest LTPA scores as the study covariate for the post-test assessment (F (1,72) = 16.06, p = 0.001, η² = 0.18). Based on the one-way ANCOVA, there were no statistically significant differences in LTPA scores between the treatment and control groups at post-test. However, the corresponding effect size and variance explained by the treatment approached a moderate level of significance (d = 0.34 and η² = 0.04).

Conclusions. Although conclusive statements about program effectiveness cannot be secured, several 'lessons learned' from this project may be 'key factors' for program improvement. Given the pilot nature of the study and the limited resources for program development and monitoring, continued examination of such motivational materials and delivery mechanisms for people with physical disabilities appear warranted.     

Reliability and construct validity of the client-centred rehabilitation questionnaire

Purpose. A key component in assessing the performance of rehabilitation services is the client's perspective. The purpose of this paper is to report on the development of a publicly available measure of client-centred rehabilitation (CCRQ) that can be used for discriminative and evaluative purposes.

Method. Mixed qualitatative and quantitative methods were used. Phase 1: Identification of seven domains of client-centred rehabilitation based on a literature review, focus groups with clients, and review by content experts. Phase 2: Item generation for the seven conceptually derived subscales and cognitive interviews with inpatient rehabilitation patients. Phase 3: Psychometric testing for internal reliability, test-retest reliability and discriminative construct validity using data from a mailed, self-administered survey to 1568 patients discharged from two large inpatient rehabilitation facilities.

Results. The seven conceptually derived subscales all have strong internal (0.72 - 0.87) and test-retest reliability (0.74 - 0.85). Discriminative construct validity is demonstrated by the ability of subscales to identify significant differences between programs within two rehabilitation facilities.

Conclusions. The results for the reliability and validity of this measure support its value for use in clinical and quality improvement work as well as research.
