Effectiveness of an individualised occupational therapy intervention programme (ABLE) using adaptational strategies on activities of daily living among persons with chronic conditions: A randomised controlled trial (RCT).

Compare the effectiveness of a problem-solving, individualised, home-based occupational therapy intervention (ABLE 2.0), to usual occupational therapy, on activities of daily living (ADL) ability in persons with chronic conditions. A single-centre, double-blinded, randomised controlled trial with 10- and 26-week follow-up. A Danish municipality. Persons with chronic conditions experiencing problems performing ADL tasks (n = 80). ABLE 2.0 was compared with usual occupational therapy. Coprimary outcomes were self-reported ADL ability (ADL-Interview Performance) and observed ADL motor ability (Assessment of Motor and Process Skills) at Week 10. Secondary outcomes were self-reported ADL ability (ADL-Interview Performance) and observed ADL motor ability (Assessment of Motor and Process Skills) at Week 26, and perceived satisfaction with ADL ability (ADL-Interview Satisfaction) and observed ADL process ability (Assessment of Motor and Process Skills) at Weeks 10 and 26. In total, 78 persons were randomly assigned: 40 to usual occupational therapy and 38 to ABLE 2.0. No statistically significant nor clinically relevant difference between group mean changes in primary outcomes was identified from baseline to Week 10 (ADL-Interview Performance [-0.16; 95% CI: -0.38 to 0.06] and Assessment of Motor and Process Skills ADL motor ability [-0.1; 95% CI: -0.3 to 0.1]). At Week 26, a statistically significant and clinically relevant difference was found in Assessment of Motor and Process Skills ADL motor ability (LS mean change: -0.3; 95% CI: -0.5 to -0.1) between groups. ABLE 2.0 was effective in improving observed ADL motor ability at 26 weeks.

Predicting length of stay with assessment of motor and process skills in subjects with acquired brain injury

ABSTRACT Background The Functional Independence Measure (FIM) is a well-established predictor of length of stay (LOS) for rehabilitation. The Assessment of Motor and Process Skills (AMPS) is a more in-depth construct for measuring activities of daily living (ADL) and may therefore be a valuable adjunct when predicting LOS. This paper aimed to investigate AMPS as a candidate predictor of LOS in a statistical model including FIM. Methods A cohort study of 647 patients with acquired brain injuries admitted for rehabilitation. LOS was analyzed in a multiple regression model with the motor and process/cognitive domains of AMPS and FIM. Results Independence in ADL process ability and FIM cognition were associated with 31% (p < 0.001) and 38% (p < 0.001) shorter LOS, respectively, relative to patients needing total assistance. Independence in ADL motor ability was associated with a 26% (p = 0.002) shorter LOS, whereas FIM motor was not a predictor. Conclusions The AMPS predicts LOS for rehabilitation at a level that is at least as good as that of FIM. Conducting the AMPS early in the course of inpatient rehabilitation provides clinicians and managers with valuable information for planning LOS.

Agreement between self-reported and observed functioning in patients with rheumatoid arthritis, osteoarthritis, and fibromyalgia, and the influence of pain and fatigue: a cross-sectional study

Objective To evaluate the relationship between self-reported and performance-based measures of functioning in rheumatoid arthritis (RA), knee osteoarthritis (OA), and fibromyalgia (FM), and the influence of pain and fatigue. Method Self-reported functioning was assessed by the Stanford Health Assessment Questionnaire, Fibromyalgia Impact Questionnaire, and Knee injury and Osteoarthritis Outcome Score. Performance-based measures of task-related physical activity included grip strength and Six-Minute Walk Test (6MWT). Assessment of Motor and Process Skills (AMPS) was used to obtain performance-based measures of activities of daily living (ADL) ability. Pain and fatigue were assessed by 100 mm visual analogue scales. Spearman’s rho correlation and regression modelling were applied. Results Correlations between self-reported functioning and performance-based measures of ADL ability were weak to moderate, and strongest in OA (r = 0.57, p = 0.002), and AMPS ADL ability measures did not enter regression models as explanatory factors for self-reported functioning. Correlations between AMPS ADL ability measures and measures of task-related physical activity were weak, except for a strong correlation between AMPS ADL motor ability and 6MWT in OA (r = 0.63, p = 0.000). The 6MWT was the only performance-based test explaining variance in AMPS motor ability (OA = 42%; FM = 11%). Pain explained variance in self-reported ability and contributed to variance in AMPS ADL motor ability measures in OA. Conclusion Self-reported and observed measures of functioning assess partly different aspects of functioning, and both approaches may therefore be relevant in a structured assessment of patients with musculoskeletal disorders.

Association Between Everyday Technology Use, Activities of Daily Living and Health-Related Quality of Life in Chronic Obstructive Pulmonary Disease.

PurposeA decline in the ability to perform activities of daily living (ADL) and ability to use everyday technology can pose threats to independent living, healthcare management and quality of life (QOL) of patients suffering from chronic obstructive pulmonary disease (COPD). Evidence of the relationship between these variables remains limited. The dual aim of this study was, first, to investigate if health-related QOL (HRQOL) was associated with quality in ADL performance and everyday technology use; second, to examine whether lung function, years with COPD diagnosis, living status or educational level affected physical and mental domains of HRQOL.MethodsThis cross-sectional study included (N=80) participants aged 46–87 years recruited at healthcare centres in the Northern Region of Denmark using a convenience sampling procedure. Data were gathered through standardized assessments and analysed using multiple regression analysis.ResultsThe regression model explained 50.6% (R2=0.506) of the variation in HRQOL–physical. The following four variables were statistically significantly associated with HRQOL – physical: years since COPD diagnosis (p=0.023), ability to use everyday technology (p=0.006), amount of relevant everyday technologies (p=0.015) and ADL motor ability (p<0.01). The regression model explained 22.80% (R2=0.228) of HRQOL – mental. Only the variable ability to use everyday technology was statistically significantly associated with HRQOL – mental (p=0.009).ConclusionQuality of ADL performance and everyday technology use seem to be associated with HRQOL in people living with COPD. The only demographic variable associated with HRQOL was years with COPD. This indicates that healthcare professionals should enhance their attention also to ADL-performance and everyday technology use when striving to increase the HRQOL of persons living with COPD.

Impact of pain, fatigue and dyspnoea on occupational performance in people with advanced cancer: A longitudinal study

Background: Pain, fatigue and dyspnoea are symptoms commonly experienced by people with advanced cancer, which may impact on their occupational performance. It is not known whether these symptoms impact their occupational performance over time.Objective: To examine correlation between pain, fatigue and dyspnoea and occupational performance and the impact of such symptoms on occupational performance over time in people with advanced cancer.Material and Methods: A longitudinal study was conducted including 242 participants assessed at baseline and after six and 12 weeks. Spearman’s rank-order test and mixed linear models were performed.Results: The correlation between pain, fatigue and dyspnoea and occupational performance at baseline spanned from trivial to moderate (Spearman’s rho: −0.004 to 0.34). Only pain had a statistically significant impact on activities of daily living (ADL) motor ability over time (p = 0.01). Participants with no pain problems had the largest decrease in ADL motor ability (−0.24 logits (95%-CI: −0.37 to −0.12)), but the observed decrease was not clinically relevant (≥−0.30).Conclusion: Pain, fatigue and dyspnoea did not seem to highly correlate with occupational performance or impact occupational performance over time of people with advanced cancer.

Hand exercise for women with rheumatoid arthritis and decreased hand function: an exploratory randomized controlled trial

BackgroundPeople with hand-related rheumatoid arthritis (RA) experience problems performing activities of daily living (ADL). Compensatory strategies to improve ADL ability have shown effective. Similarly, hand exercise has shown effect on pain, grip strength, and self-reported ability. A combination has shown positive effects based on self-report, but self-report and observation provide distinct information about ADL. The purpose of this study was to examine whether hand exercise as add on to compensatory intervention (CIP) will improve observed ADL ability in RA.MethodsWomen (n = 55) with hand-related RA were randomized to CIPEXERCISE (intervention) or CIP only (control). CIP is focused on joint protection, assistive devices, and alternative ways of performing AD. The hand-exercise program addressed range of motion and muscle strength.Primary outcome was change in observed ADL motor ability measured by the Assessment of Motor and Process Skills (AMPS). Baseline measures were repeated after 8 weeks.ResultsImprovements in ADL motor ability in CIPEXERCISE (mean change = 0.24 logits; 95% CI = 0.09 to 0.39) and CIPCONTROL (mean change =0.20 logits; 95% CI = 0.05 to 0.35) were statistically significant, with no differences between groups (mean difference = 0.04 logits; 95% CI = − 0.16 to 0.25). Thirteen (46.4%) participants in the CIPEXERCISE and 12 (44.4%) in the CIPCONTROL obtained clinically relevant improvements (≥ 0.30 logits) in ADL motor ability; this group difference was not significant (z = 0.15; p = 0.88).ConclusionAdding hand exercise to a compensatory intervention did not yield additional benefits in women with hand-related RA.The study was approved by the ethics committee 14th of April 2014 (H-3-2014-025) and registered at ClinicalTrials.gov 16th of May 2014 (NCT02140866).

Subgroup effects of occupational therapy-based intervention for people with advanced cancer

Background: Many people with advanced cancer have decreased ability to perform activities of daily living (ADL). We recently performed a randomized, controlled trial (RCT) assessing the efficacy of an occupational therapy-based program, the ’Cancer Home-Life Intervention’ in people with advanced cancer (N = 242) and found no overall effects on ADL ability. However, heterogeneity of treatment effect may disguise subgroup differences.Objective: To investigate whether subgroups of people with advanced cancer gain positive effects from the ‘Cancer Home-Life Intervention’ on ADL ability.Material and method: An exploratory subgroup analysis including 191 participants from a RCT. The outcome was ADL motor ability measured by the Assessment of Motor and Process Skills (AMPS). Subgroups were defined by age, gender, years of education, type of primary tumor, functional level, and activity problems.Results: The ‘Cancer Home-Life Intervention’ had no statistically significant effect in the six subgroups. Modifying effects of age (0.30 [95% CI: −0.05 to 0.64]) and gender (0.23 [95% CI: −0.11 to 0.57]) were not found.Conclusion: There were no subgroup effects of the ‘Cancer Home-Life Intervention’on ADL motor ability. Some indications suggest greater effects for those aged below 69 years; however, this result should be interpreted with caution.

Ability to perform activities of daily living among patients with bipolar disorder in remission

Aims: Patients with bipolar disorder often experience disability in terms of cognitive impairments and activity limitations even in remission. However, knowledge is sparse concerning the ability to perform Activities of Daily Living (ADL) during remission. The aim of this study was to (1) investigate the observed and self-reported ability to perform ADL tasks and (2) examine the association between observed and self-reported ability to perform ADL in patients with bipolar disorder in remission. Methods: The observed ADL ability was assessed with the Assessment of Motor and Process Skills, a standardized assessment providing interpretation of ADL ability in relation to competence, independence, and normative age expectations. Self-reported ADL ability was assessed with the standardized ADL-Questionnaire. Results: Forty-three patients with bipolar disorder in remission (median age 35 years, range 19–58 years) were assessed and overall, they displayed decreased observed ADL motor and ADL process ability relative to normative age. They exhibited increased physical effort, clumsiness or fatigue and/or inefficiency, there was concern for safe task performance and one-third may need assistance to live in the community. While participants reported decreased ADL ability, especially within instrumental ADL, they had a tendency towards evaluating themselves as more competent than what was observed. No relationships between measures of observed and self-reported ADL ability were found. Conclusion: Overall, patients with bipolar disorder in remission showed decreased ability to perform ADL. Clinical practice and future studies are recommended to use both observation-based and self-reported assessments of the ability to perform ADL tasks to fully capture disability in bipolar disorder.

Differences in activities of daily living (ADL) abilities of children across world regions: a validity study of the assessment of motor and process skills.

One important goal of paediatric occupational therapy services is to improve activities of daily living (ADL) abilities of children. In order to plan and evaluate the effectiveness of targeted interventions, valid assessments are critically needed. The Assessment of Motor and Process Skills (AMPS) is an internationally standardized assessment of ADL performance that has not been validated for use with children in Middle Europe. To evaluate for (i) significant differences in mean ADL motor and mean ADL process ability measures among children from Middle Europe compared with children from North America, UK/Republic of Ireland, Nordic countries, Western Europe, Australia/New Zealand and Asia; and (ii) meaningful differences between the international age-normative means of the AMPS and those for children from Middle Europe. We analysed data of children across world regions extracted from the international AMPS database using many-facet Rasch and two-way anova analyses and by estimating contrasts to evaluate for significant group differences. anova analyses of data for 11 189 children ages 2-15 revealed significant effects for mean ADL motor and ADL process ability by region [F ≥ 15.32, d.f. = (6, 11 091), MSE ≥ 0.20, P < 0.001, ή(2) ≥ 0.008], and age [F ≥ 253.47, d.f. = (13, 11 091), MSE ≥ 0.20, P < 0.001, ή(2) ≥ 0.229], and a significant interaction effect for mean ADL process ability [F = 1.48, d.f. = (78, 11 091), P = 0.004, ή(2) = 0.010]. Out of 168 estimated contrasts between Middle Europe and the other world regions for mean ADL motor and ADL process ability, seven were statistically significant (4.17%), but none exceeded ±1SE from the international means. The AMPS remains free of relevant differences in mean ADL ability measures between Middle Europe and other world regions, indicating that the international age-normative mean values are likely to be applicable to children from Middle Europe. The AMPS can be used internationally to evaluate ADL performance in children and to determine if the child is eligible for occupational therapy services.

Comparison of Activities of Daily Living Ability of Older Adults Who Are Homebound and Nonhomebound

ABSTRACTThe objective of this study was to compare the activities of daily living (ADL) ability of older adults who were chronically homebound to older adults who were nonhomebound.The participants were 40 older adults 60 years of age or older, 20 homebound and 20 nonhomebound. The two groups did not differ in mean age, gender distribution, ethnicity, marital status, living situation, or type of housing. The older adults who were homebound had significantly more conditions than those who were nonhomebound.T tests revealed statically significant differences in the mean Assessment of Motor and Process Skills ADL motor and ADL process ability measures of older adults in the homebound and nonhomebound groups, with the latter group demonstrating higher ADL ability measures. Based on a power analysis indicating a need for 10 persons in each group, the nonhomebound group was subsequently divided into two subgroups, those who needed assistance to perform ADL from paid staff and/or family members and those who performed ADL independently. The results of two analyses of variance revealed that participants who were chronically homebound and those who were nonhomebound and had assistance had significantly lower ADL motor ability and ADL process ability than those who were nonhomebound and independent. The homebound group and the nonhomebound group with assistance did not differ significantly in ADL motor or ADL ability.The findings support the need for occupational therapists to provide services for older adults who have ADL limitations regardless of their homebound status.

Detecting Differences in Activities of Daily Living Between Children With and Without Mild Disabilities

We evaluated whether the Assessment of Motor and Process Skills (AMPS) measures are valid for detecting differences in activities of daily living (ADL) ability among children with and without mild disabilities. Retrospective data from the AMPS database were analyzed using many-facet Rasch analyses and forced regression analyses to evaluate for significant group differences. Regression analyses of data for 10,998 children ages 4-15 who met the inclusion criteria revealed significant Age × Group interaction effects (B ≥ 0.23, T ≥ 6.20, p ≤ .001). Post hoc t tests revealed significant group differences in ADL ability at all ages beyond age 4. ADL process ability effect sizes were moderate to large at all ages, and ADL motor ability was mostly moderate to large at ages 6 or older. These findings support the validity of the AMPS measures when used to identify ADL problems among children with mild disabilities.

Evaluation of Activities of Daily Living Ability and Awareness among Clients in a Forensic Psychiatry Evaluation Unit in Sweden

Introduction: The aim of this exploratory study was to investigate activities of daily living (ADL) functioning for clients in a forensic psychiatry evaluation unit and also to investigate the relationship between ADL functioning and awareness of their ability to perform ADL. Method: The sample consisted of 35 participants at a forensic psychiatry evaluation unit in Sweden. ADL was investigated using the Assessment of Motor and Process Skills (AMPS) and awareness of ability was investigated using the Assessment of Awareness of Ability (A3). Results: The ADL mean motor ability for the participants was 1.68 logits and the process ability showed an ADL mean value of 0.83 logit. The mean value of awareness was 0.60 logit. A majority of the participants demonstrated ability measures below the cut-off criteria in the AMPS, which indicates that they might need support to function in the community. There was also a significant relationship between awareness of ability and ADL motor ability (rho = 0.49, p&lt;0.01) and ADL process ability (rho = 0.77, p&lt;0.01). Conclusion: Clients in forensic psychiatry demonstrate limited ability in ADL, associated with a limited awareness. Clients in forensic psychiatry may also need assistance to live in the community, which suggests that occupational therapy may be offered to these clients in order to prepare them to manage in the community.

Observation-based assessment of functional ability in patients with chronic widespread pain: A cross-sectional study

Knowledge about functional ability, including activities of daily living (ADL), in patients with chronic widespread pain (CWP) and fibromyalgia (FMS) is largely based on self-report. The purpose of this study was to assess functional ability by using standardised, observation-based assessment of ADL performance and to examine the relationship between self-reported and observation-based measures of disability. A total of 257 women with CWP, 199 (77%) fulfilling the American College of Rheumatology tender point criteria for FMS, were evaluated with the Assessment of Motor and Process Skills (AMPS), an observation-based assessment providing linear measures of ADL motor and ADL process skill ability (unit: logits). A cutoff for effortless and independent ADL task performance is set at 2.0 for the motor scale and 1.0 for the process scale. A total of 248 (96.5%) had ability measures below the 2.00 ADL motor cutoff and 107 (41.6%) below the 1.00 ADL process cutoff, indicating increased effort and/or inefficiency during task performance as well as a potential need of assistance for community living. Mean ADL motor ability measure was 1.07 and was significantly lower in patients diagnosed with FMS than plain CWP (1.02 vs 1.27 logits, P = .001). Mean ADL process ability measure was 1.09 logits and was without difference between FMS and plain CWP (1.07 vs 1.16 logits, P = .064). Only weak to moderate correlations between self-reported functional ability and observation-based AMPS ability measures were observed. The results of the study support the notion of considerable performance difficulties in women with CWP. The everyday life problems are substantial and place the individual at risk of need of support for community living.

Performance-based assessment of activities of daily living (ADL) ability among women with chronic widespread pain

Functional ability, including the ability to perform activities of daily living (ADL), is considered a core outcome domain in chronic pain clinical trials and is usually assessed through generic or disease-specific self-report questionnaires. Research, however, indicates that self-report and performance-based assessment of ADL offer distinct but complementary information about ability. The present study, therefore, investigated the applicability of a performance-based measure of ADL ability, the Assessment of Motor and Process Skills (AMPS), among 50 women with chronic widespread pain. The investigated psychometric properties of the AMPS included discrimination between a sample of healthy women and those with chronic widespread pain, as well as stability when no intervention was provided and sensitivity to change following intervention. Data were obtained based on a repeated measures design performing AMPS evaluations twice pre- and twice post-rehabilitation. Results indicated that the ADL motor ability measures of the participants were significantly lower than those of healthy women of same age, the ADL motor and ADL process ability measures remained stable when no intervention was provided and the ADL motor ability measures were sensitive to change following a 2-week interdisciplinary rehabilitation program. A weak correlation ( r s = −0.35) was found between self-reported ADL ability as measured by the physical function subscale of the Functional Impact Questionnaire (FIQ) and performance-based ADL motor measures, and no correlation ( r s = −0.02) was found between FIQ ADL measures and ADL process ability, supporting the need for both performance-based and self-reported assessment of ADL.

Activities of daily living for old persons in primary health care with chronic heart failure

Chronic heart failure (CHF) is a common condition among Europe's aging population. Findings indicate that CHF patients must make significant changes in many aspects of daily life. Previous studies of older primary health-care participants and their activities of daily living (ADL)-ability are rare. The aim of this study was to describe ADL-ability in older people with CHF syndrome. The factors considered were dependence on others, perceived strain, quality of performance, and the association between The New York Heart Association classification (NYHA) and ADL-ability. The participants, recruited from a primary health-care centre, had symptoms indicating CHF and were diagnosed by a cardiologist. Forty persons over 65 years (mean age 81), participated in the study and self-reported co-morbidity was frequent. The Assessment of Motor and Process Skills (AMPS) and the Staircase of ADL were used to describe ADL-ability. Most participants were independent with respect to personal activities of daily living (PADL), and 75% were dependent in one or more instrumental activities of daily living (IADL), usually shopping. Most participants perceived strain, and only three could perform all ADL without strain. Age had a significant impact on ADL performance (motor measures: OR 7.11, CI 1.19-42.32, p = 0.031 and process measures: OR 8.49, CI 1.86-38.79, p = 0.006). However, participants showed lower ADL motor and process ability in AMPS compared with well persons of the same age. Participants in NYHA III/IV (adjusted for age), had significantly increased effort (under motor cut-off) when performing ADL-tasks (OR: 15.5, CI 2.40-100.1, p = 0.004) compared to those in NYHA I/II. Older persons in primary health care with CHF exhibit a high amount of dependence, perceived strain and increased effort during performance of ADL. There is an association between NYHA class III/IV and a decreased ADL-ability (AMPS motor ability) even when adjusted for age.

Behavioral and Physiologic Response Measures of Occupational Task Performance: A Preliminary Comparison Between Typical Children and Children With Attention Disorder

To compare performance on the Assessment of Motor and Process Skills (AMPS), a measure of functional task performance and physiological responses (salivary cortisol levels) during AMPS administration, between typically developing children and children diagnosed with attention deficit hyperactivity disorder (ADHD). In this quasi-experimental study, independent t tests, and mixed, repeated measures analysis of variance were conducted to compare a group of typically developing children (n = 21) with a group of children with ADHD (n = 12) on two dependent measures: (a) the AMPS and (b) salivary cortisol. Salivary cortisol, a stress hormone, was taken at three time points, baseline, mid-way through AMPS administration, and 20 min following AMPS administration. Significant differences were found on the activities of daily living (ADL) process ability measure of the AMPS (p = .001) and the ADL motor ability measure (p = .04), with the ADHD group performing more poorly than typical children. There was no significant group (ADHD vs. control) by time period interaction effect on cortisol levels. Overall, the cortisol levels of the ADHD group were higher than the levels of those in the control group (p = .02). Cortisol levels tended to drop significantly over time (p = .01) for both groups, however the patterns differed somewhat between groups. Cortisol levels of the typical children dropped at the final time period (20 min post-AMPS administration) whereas the levels of the children in the ADHD remained higher during this time period. This interaction effect approached, but did not reach, statistical significance (p = .15). The results of this investigation suggest that the AMPS is sensitive to detecting functional performance concerns, and both motor and process skill deficits, associated with ADHD, and therefore may be a useful assessment tool with this population. Data also suggests that cortisol expression to a well-known ADL task may be lower if the task is not overly challenging for the individual, and provides support for further study of the role of cortisol with disorders of attention.

Gender differences in the performance of activities of daily living

Merritt BK, Fisher AG. Gender differences in the performance of activities of daily living. Arch Phys Med Rehabil 2003;84:1872–7. Objectives To verify that the activities of daily living (ADL) motor and process skill items and tasks in the Assessment of Motor and Process Skills (AMPS) are free from gender bias, and to compare mean differences in ADL motor and process ability between men and women. Design Descriptive comparison; convenience sample. Setting Existing data from the AMPS database. Participants Potential participants included nonwell persons (age range, 18–99y) matched within 3 age groups, first by functional level and then by diagnostic category. The resulting sample included 9250 men and 9250 women. Interventions Not applicable. Main outcome measure The AMPS, a standardized observational assessment of the quality of ADL task performance. Results None of the AMPS task calibrations and 1 motor skill item calibration (Lifts) demonstrated an observable difference between men and women. Men had higher ADL motor ability (F 1,18494=11.58, P<.01) and women had higher ADL process ability (F 1,18494=76.18, P<.01). Conclusion The results suggest that the AMPS is free of gender bias. Although differences were found between men and women in mean ADL motor and process ability, they were not considered clinically detectable differences.

Client-Centred Occupational Therapy for Persons with Mental Retardation: Implementation of an Intervention Programme in Activities of Daily Living Tasks

The aim of this study was to implement a single-case design to evaluate the outcomes of a specified occupational therapy intervention programme. The intervention programme was based on a client-centred top-down approach and followed the Occupational Therapy Intervention Process Model. The interventions included both restorative and adaptive strategies to improve performance of the activities of daily living (ADL) tasks the participants defined as relevant and meaningful. Three women with moderate mental retardation living alone in apartments with support from professionals were included in the study. The Assessment of Motor and Process Skills was used to evaluate for changes in ADL motor and ADL process ability. The Assessment of Awareness of Disability was used to evaluate changes in the client's awareness of disability. The results showed improvements for all participants but patterns of changes were different between the participants and the outcome variables. ADL process ability was the only outcome variable that improved in all participants. The results are discussed in relation to the design used for evaluating intervention efficacy. Future improvements in the process of evaluating occupational therapy interventions are suggested.
