The validity of occupational performance assessments: a validity generalization meta-analysis

Effects of vocational rehabilitation group intervention on motivation and occupational self-awareness in individuals with intellectual disabilities: A single blind, randomised control study

BACKGROUND

The aim of this study was to investigate the effects of a vocational rehabilitation group intervention on motivation and occupational self-competence in individuals with intellectual disability.

METHODS

A single-blind, randomised controlled study design was used. The intervention group (IG) received the group-based intervention alongside the individualised vocational rehabilitation (IVR) and the control group (CG) continued receiving only the IVR for 8 weeks. In order to assess motivation and occupational self-competence, Objective Achievement Motivation Test (OLMT) and Occupational Self-Assessment (OSA) were used.

RESULTS

Forty-nine individuals were enrolled to the study and randomised into IG (n = 24) and CG (n = 25). Two groups were similar at baseline in terms of demographic qualities, OLMT and OSA scores (p > 0.05). After the intervention, the IG showed significant improvements in all assessments (p < 0.05), however the CG showed improvements only in OLMT sub-tests (p < 0.05).

CONCLUSIONS

The group-based intervention program was effective in increasing occupational self-competence and motivation.

Occupational Competence and Activities of Daily Living Performance in Bronchial Asthma : Compétence professionnelle et performance des activités de la vie quotidienne pour la bronchite asthmatique

Background. Activity restriction is one of the most common symptoms reported by people living with bronchial asthma. Purpose. The study aimed to determine occupational competence and values in people living with bronchial asthma and compare with the occupational competence and activities of daily living (ADL) of healthy controls. Methods. Twenty individuals with asthma and 20 healthy controls were enrolled. Occupational competence and values were assessed using the Occupational Self-Assessment (OSA) questionnaire. Restriction of ADL was determined using the London Chest ADL Scale. Findings. Occupational competence was lower, and all London Chest ADL scores were significantly higher in asthma individuals compared to controls (p < .05). The most affected parameters reported by asthma individuals on the OSA were the ability to concentrate, perform physical tasks, work toward goals, and use abilities effectively. Implications. Evaluating occupational competence in people living with bronchial asthma is important to identify their occupational problem areas and provide appropriate interventions.

Validity of the Turkish Occupational Self Assessment for Elderly Individuals

Occupational therapy practices in Turkey are increasing each year, but rehabilitation practitioners working in the occupational therapy field have limited instruments. The aim of this study was to analyze the validity of the Turkish version of the Occupational Self Assessment (OSA), which is based on the Model of Human Occupation. The data were analyzed using exploratory and confirmatory factor analyses to determine construct validity. The Turkish OSA was administered with the World Health Organization Quality of Life-Old (WHOQOL-OLD) and the Functional Autonomy Measurement System (SMAF) to 117 elderly individuals to determine convergent validity. The Turkish OSA has acceptable construct validity scores (exploratory and confirmatory factor analyses). SMAF and WHOQOL-OLD Scales showed a moderately significant relationship with OSA competence total scores ( p < .01). The results indicate that the OSA is a valid instrument for determining occupational competence and values in elderly Turkish individuals.
