    Dimensionality and concurrent validity of the Handler DAP Anxiety Index
    (Wichita State University, Department of Psychology, 1982) Sims, Jeannie; Bolton, Brian, 1939-; Dana, Richard H. (Richard Henry), 1927-
    The Handler Anxiety Index was developed to provide a measure of anxiety from the Draw-A-Person (DAP) protocol. The present study examined the dimensionality and concurrent validity of the Handler Index against two criteria, clinical diagnosis and the 16 PF anxiety scales. The results were as follows: (a) The median reliability estimate for the 20 Handler items was 0.97, (b) The Handler items were found to be heterogeneous with respect to item-total structure and saturation with drawing quality, (c) Factor analysis of the Handler Index was produced six orthogonal dimensions: Poor Quality, Correction, Three-Dimensionality, Expansion-Constriction, Overinclusiveness, and Inadequate Control, and (d) There was no pattern of significant relationships in the correlations of the six Handler factors with the two independent anxiety criteria. In summary, the results of the investigation suggest that there are no subsets of drawing elements that are valid indicators of anxiety.

    Transdiagnostic symptoms of depression in alcoholism
    (Wichita State University, Department of Psychology, 1982) Steer, Robert A.; McElroy, Margo G.; Beck, Aaron T.
    Principal components analyses were performed on the intercorrelations among the 21 items of the Beck Depression Inventory (BDI) and 15 items of NIAAA's alcohol Impairment Index for 101 men admitted for alcoholism treatment at large, metropolitan community mental health center. An inter-battery principal-components analysis performed among the five salient components initially found for the BDI and the four identified for the Impairment Index revealed one significant canonical variate representing affective and somatic symptoms. The symptoms reflecting cognitive distortions in self-concept may afford a better picture of the severity of depression in alcoholics than affective and somatic symptoms.

    Deciding on the ratio of number of subjects to number of variables in factor analysis
    (Wichita State University, Department of Psychology, 1982) Baggaley, Andrew R.
    The appropriate rations among the number of subjects, variables, and retained factors in a factor analysis has been much disputed. A theoretical rationale is developed for deciding on the ration of subjects to variables. Some rules of thumb are suggested for this and related issues.
