“…The mutual cohesive interactions of these "needs" in an individual human shaped the quality-of-life construct. 27,28 There are certain theoretical assumptions that were made during the design phase. First, the participants in this study were chosen from the continuation phase of MDR TB treatment.…”

Background: Multidrug-resistant tuberculosis (MDR TB) affects the physical, psychosocial and inter-relationship structure and thus quality of life (QoL) of an individual. WHO QOL BREF is presumed to capture the QoL construct. This study investigates the diagnostic accuracy and construct of WHO QOL BREF from a psychometric perspective and complements and converges findings through classical test theory. Methods: The instrument validity study was conducted in a district of Central India amongst the microbiologically confirmed MDR TB cohort of year 2017 (n=98). We calculated global and domain-specific Cronbach alpha and Inter-domain Pearson correlations. The dichotomized items were fitted through Rasch model for item endorsement, response pattern and for variation inconsistencies. Item Characteristic Curves and person item maps were also plotted. We performed DIF (Differential Item Functioning) to check the effect of subgroups on underlying traits. This was complimented with an Exploratory Factor Analysis (EFA) using oblique ProMax rotation. The optimum number of factors were identified by Scree plot and parallel analysis approach and the emerging factor structure was compared with the result obtained through the Rasch model. Results: The global Cronbach’s alpha was 0.94 (95% CI 0.92-0.96). Social relationship domain had poor correlations with all three domains (r=0.42, r=0.41 r=0.58), higher beta values and less discrimination. DIF showed a differential response by gender. There was a visual clustering and a non-uniform distribution of items across the perceived QoL. A 3-factor model emerged through EFA and was reframed on the notion of self-concept. Items related to pain, medical aid had significant misfit and weak factor loading while items of sexual activity and social support had relatively poor performance in Infit, Wald, DIF on factor loading parameters. Conclusions: The study indicates the possible deviation of scale from theorized dimensional construct in Indian MDR TB context more with the items of the social relationship domain.

“…Mosteller & Burdick (1989) have reviewed the general problems encountered in the assessment of any technology in health care. They pointed to the need for carefully planned randomised controlled trials and for the development of improved standard isation of outcome measures such as mortality stat istics and quality of lifemeasures.…”

Population movements away from large cities and congestion in urban areas create problems for the delivery of psychiatric care which are compounded by the move towards greater care in the community. These developing service patterns require adequate methods of communication between service com ponents. There is a proliferation of new technology offering opportunities for improved national and international communication in psychiatry as in other branches of medicine. It will be important to decide which technological innovations will improve the efficiency of service delivery rather than end up as expensive 'gadgets', or solutions looking for prob lems to solve. In this paper the use of interactive television in psychiatry is reviewed and the impli cations for the evaluation of new communications technology are discussed.

“…But innovations that may make theoretical sense may or may not prove useful in practice; they therefore must be evaluated. Technology assessment, which Mosteller and Burdick (8) define as a way of "learning from controlled experience," is therefore receiving increasing attention.…”
