| pubmed-article:8235805 | pubmed:abstractText | An instrument designed to assess potentially challenging cognitive and social activities in a wide range of both psychiatric and normal study populations is described in this paper. The technique used combines traditional time budget approaches with an additional, significant component, i.e. a rating indicating the amount of challenge for each activity that is sampled. Separate ratings reflecting the subject's and the interviewer's perspective are generated. Along with a detailed description of this weighted time budget instrument, preliminary data regarding practicality, reliability and validity are reported. An analysis based on time budget interviews with 30 schizophrenic patients showed overall interrater agreement to average 84% (kappa = 0.72). In a study with a possible bearing on the concurrent validity of the instrument, relapsing schizophrenics significantly differed from stable subjects in weighted time budget indices. | lld:pubmed |
