[Controlled trials on the efficacy of occupational therapy with elderly. Part I: Research question, search strategy and methodological quality of trials].

OBJECTIVE: To investigate how far controlled trials give evidence for the assumption that occupational therapy treatment improves or stabilises the competence, autonomy or satisfaction of elderly while performing every day activities. METHOD: Clinical trials with randomised, quasi-experimental or crossover control group design and "occupational therapy" as the main subject were identified by an electronic search of the medline database. The criteria for the analysis were derived from the CONSORT-Statement and adapted for occupational therapy. They relate to the quality of sample, intervention, measurement and data analysis. RESULTS: The 31 identified studies (RCT, n=23; quasi-experimental, n=2; crossover, n=6) were mainly conducted in Great Britain, USA and Canada, but not in Germany. They are heterogeneous regarding the characteristics and size of samples, the outcome variables and treatment approaches. They give evidence for a significant efficacy of occupational therapy with elderly, but also show some methodological shortcomings. CONCLUSION: While on an international level the positive potential of occupational therapy for the elderly is evident, there is a strong need for further studies in Germany. Therefore a methodological harmonization and a co-operation with occupational therapy research and occupational science emerging currently in Europe are recommended.

[Controlled trials on the efficacy of occupational therapy with elderly. Part II: Evidence for prioritized diseases and disabilities].

OBJECTIVE: To identify the evidence for the efficacy of occupational therapy on prioritized diseases and disabilities of the elderly. METHOD: Reviews, meta-analyses and clinical trials with control group design regarding "occupational therapy" were identified by an electronic search of pubmed and reviewed based on the CONSORT-Statement. The study results were summarised in regard to diseases and commented considering further literature. RESULTS: A total of 31 studies were identified: 10 on stroke, 6 on dementia, 5 on prevention of falls, growing loneliness or inactivity, 4 on need of nursing care, and 6 on other diseases or disabilities. There is evidence for a positive efficacy of occupational therapy on the level of several controlled trials or reviews. CONCLUSION: Especially in Germany, further research specific to occupational therapy is needed in the fields of depression, diabetes mellitus and nursing care in the community.

[The occupational therapy assessment: implementation in practice].

The "Ergotherapeutische Assessment" (EA, occupational therapy assessment instrument) is designed as a generic instrument assessing disabilities with consequences on everyday life. It is tested for its practicability and measurement properties and suitable for adult patients treated with occupational therapy. It can be used for routine documentation, as a result-indicator for data based quality management and in outcome research. The EA is integrated in an assessment network currently in development intended for occupational therapy, physiotherapy, speech therapy and, optionally, for further professions. The profession-specific approach should enhance the intrinsic motivation for self-evaluation and thus the learning organisation.

[Psychometric analyses of occupational therapy assessment].

PURPOSE: In German-speaking countries standardised assessments measuring the specific aspects of occupational therapy in adults are missing. The Occupational Therapy Assessment (OTA) was introduced by the authors during 2000 in the context of a field study regarding acceptance, practicability and the influence of the instrument on process quality. The purpose of this study was to test the psychometric properties of the OTA. METHODS: : OTA was applied by 76 occupational therapists from 44 institutions to 833 consecutive patients. Additionally, the Mini Mental State Examination (MMSE) was applied. Patients completed established German instruments measuring functional capacity (Funktionsfragebogen Hannover - polyartikuläre Erkrankungen; FFbH-P), body complaints (Beschwerdenliste; BL) and general health (Indikatoren des Reha-Status; IRES). 59 randomly selected patients were assessed independently by two therapists. 42 randomly selected patients were assesses twice for test-retest reliability. RESULTS: : For the domains 'activities of physical self-supply', 'activities of independent living', and the three domains 'consequences of sensomotor/neuropsychological/psychosocial functioning on everyday life' internal consistency (Cronbach alpha: 0.90-0.97), test-retest reliability (intraclass correlation coefficient: 0.93-0.99) and interrater reliability (kappa: 0.72-0.82) were high. Overall, the concurrent validity of the domains with corresponding scales or subscales of the MMSE, FFbH-P and IRES is satisfactory. In addition, the domains are sensitive to change. CONCLUSION: : The OTA is a standardised assessment measuring the specific aspects of occupational therapy reliably, valid, sensitive to change and sufficiently comprehensive.

[Ergotherapy assessment: field study of acceptance, practicability and process quality].

There is need for comprehensive assessment of patients suitable for occupational therapy. The "Ergotherapeutische Assessment" (EA) occupational therapy assessment instrument has been developed recently by a group of experts in the field. Its main purpose is to significantly support occupational therapists in diagnostics, planning, communication and evaluation of therapeutic outcome. In a first step, EA was tested in a field study with regard to practicability, acceptance, and its effects on process quality. The EA was applied in 329 patients by 22 occupational therapists (office, institution) who had been specially trained (handbook, instruction session) prior to the study. In addition, participants had to answer standardized evaluation forms with respect to the general therapeutic success, relevant functional changes possibly not covered by the EA, and professional benefit in the areas under investigation. In summary, the value for practicability as described using a 10-point scale was 5.8, and 7.6 for acceptance. With regard to process quality, the ratings were 7.3 for diagnostic effect, 6.0 for definition of therapeutic aims, and 6.8 for improvement of communication between members of the rehabilitation team. The internal consistency of the five individual modules of the instrument as calculated by Cronbachs alpha was between 0.72 and 0.95. Changes considered relevant by the participants and not reflected by the instrument accounted for 9% only. The correlation coefficient for the evaluated general success of the patients and category changes found on the basis of EA severity ratings was 0.48.

[Speech therapy assessment: field study on psychometric properties, practicability, acceptance and process quality].

OBJECTIVE: to investigate the internal consistency, responsiveness, discriminative validity, practicability, acceptance and process quality of a recently developed Speech Therapy Assessment (STA) under routine work conditions of speech and language therapists in German speaking countries. Since standardised, generic and ICF-oriented assessment tools for documentation and evaluation of speech therapy interventions for adult clients are missing in German speaking countries and existing tests cover only sub-areas, the STA has been developed in the years 1995 to 2002. By means of different domains, speech and language therapists assess client (1) communication, (2) aphasia, (3) speech apraxia, (4) dysarthria and (5) dysphagia as well as (6) her or his dealing with corresponding disabilities. METHODS: 17 therapists from 14 institutions applied the STA to 260 adult clients with language, speaking or swallowing disorders. The clients were included in the study consecutively over a period of 7 month. After this period, the therapists completed a questionnaire regarding the benefit and practicability of the STA. Cronbach alpha was calculated as indicator for internal consistency, effect sizes (standardised response means) for responsiveness and ROC values for discriminative validity. The answers of the questionnaire about the benefit of the STA were evaluated both, quantitatively and qualitatively. RESULTS: The internal consistency and discriminative validity were high (Cronbach alpha: 0.79 to 0.95; ROC-values: 0.84 to 0.98). Effect sizes regarding responsiveness were moderate (standardised response means: 0.46 to 0.78). On a 5-step Likert scale (1 = very good, 5 = inadequate), the therapists rated the average (standard deviation) benefit of the STA with: practicability 2.6 (1.2), acceptance 2.8 (1.3), impact on diagnostics 2.8 (1.3), impact on finding therapeutic goals 3.5 (1.2), impact on communication with other rehabilitation partners 2.7 (1.5) and overall judgement 2.6 (0.9). CONCLUSION: The STA fulfils essential quality criteria of the classical test theory. The involved therapists assessed the benefit of the STA as satisfactory. In addition, they pointed out concrete improvement potential for the implementation in practice. It is planed to investigate a refined version of the STA in a multi centre validation study.
