Robustness of normal theory methods in the analysis of linear latent variate models

The structure of the covariance matrix of sample covariances under the class of linear latent variate models is derived using properties of cumulants. This is employed to provide a general framework for robustness of statistical inference in the analysis of covariance structures arising from linear latent variate models. Conditions for normal theory estimators and test statistics to retain each of their usual asymptotic properties under non-normality of latent variates are given. Factor analysis, LISREL and other models are discussed as examples.     

Family system functioning: behavior in the laboratory and the family treatment setting

The Family System Functioning (FSF) scale is a new instrument for measuring dimensions of the intrafamilial environment thought to be important in recovery from major psychiatric illness. Modest statistical correlations were obtained when FSF ratings of laboratory-based family interactions were compared with researcher-guided therapist ratings of FSF based upon the family's behavior in family therapy sessions during the subsequent month. The data from these two settings provide support for the validity of some of the scales. Because of the modest size of the correlations, however, behavior in the laboratory setting may not always be an accurate indicator of how the family will behave in the early weeks of family therapy.     

Family Therapy in Trouble: Psychoeducation as Solution and as Problem

The authors cite clinical literature attesting to the importance of recognizing the family, rather than the individual, as the proper locus of conceptualizing, diagnosing, and treating mental illnesses. Specifically with regard to severe psychiatric illnesses, in particular schizophrenia, family dysfunction contributes to the emergence of the illness, significantly affects its course, and strongly influences the achievement and maintenance of treatment gains. Currently, a movement is afoot to limit sharply the amount and kind of treatment offered to schizophrenic patients and their families. Rooted in a “medical model” or “biogenic” view of the etiology of schizophrenia, this school of thought prescribes psychoeducation as the family treatment of choice. The present article looks at some misconceptions regarding treatment that prompted a widespread turning away from psychoanalytically oriented family psychotherapy for schizophrenic patients and their families, examines the reductionism (biological and behavioral) inhering in the exclusive use of psychoeducation, and looks at the clinical dangers of such reductionism. Finally, it proposes that family psycho-therapists should not abandon a concern with the inner lives of severely ill patients and their families in the face of spuriously generalized claims made by reductionist researchers.
