Known Group Validity of Assessment of Work Performance for Thai Homeless People

BackgroundSubstance use and mental disorders are highly prevalent in Thai homeless people living with no mental health recovery. The lack of psychosocial occupational therapists may be one huge problem for none of the measurement outcomes for clinical utility. We aimed to determine the known-group validity of the Assessment of Work Performance (AWP) with good content and internal consistency reliability. MethodsParticipants (N = 60) were recruited by screening with no cognitive impairment, no psychiatric symptoms, independent self-care, and on-the-job assignment at Nonthaburis destitute home. Mann-Whitney U tests firstly found a significant difference in process skills between males and females (p < .05). Data analysis of the ceiling effect was then conducted to design using cleaned samples (N = 22), and the Mann-Whitney U tests secondly found a significant difference in communication skills between males and females (p < .05). ResultsThere were no associations between the frequency of genders and substance abusers were computed using cross-tabulation (N = 60 versus N = 22). Besides a corrected sample, natural contexts of too easy job selection, no preparatory of supported employment, and non-purposeful living activities may be confounding factors of avolition, poor habit, and inactive life roles without wellness at the end of life. ConclusionThese preliminary results suggest a useful AWP with good known-group validity for measuring outcomes among vulnerable people and describing how to improve motor, process, and interactive communication skills based on the Model of Human Occupation (MOHO) in occupational therapists and Mental Health Recovery (MHR) workers.
