The Beck Anxiety Inventory was administered to 105 outpatients between 13 and 17 years old who were diagnosed with various types of psychiatric disorders. A principal factor analysis was performed, and two factors were found representing subjective and somatic symptoms of anxiety. The item compositions of these factors were comparable to those previously described for adolescent inpatients. The results are discussed as supporting the use of the inventory for evaluating self-reported anxiety in outpatient adolescents.

Self Actualization

Items from the 40-item Brief Index of Self-actualization were submitted to principal factor analysis with promax and oblique rotation ( N = 620). With eigenvalues greater than 1 and factor loadings of .40 or higher, 32 items were retained as four factors, without overlap. A revised Brief Index of Self-actualization is presented as an improved measure of constructs underlying Abraham Maslow's description of a self-actualizing person.

AbstractThe Carrión lacustrine basin (≈10 km2), central Spain, is filled with Neogene-Quaternary sediments (20–25 m thick) rich in palygorskite. Two clay units of ∼15 m thick are of particular interest in the basin. The lower one contains over 75% phyllosilicates (palygorskite up to 90%, smectites and illite) in marginal areas (facies A), and it is laterally bound by a distal facies (B) also rich in clay minerals (smectites and illite, and some palygorskite) and gypsum, and includes dolomitic marl intercalations. The composition at the top is primarily marly, with some gypsum (C). The upper clay unit, mainly clay-size material, (D) is rich in smectites, palygorskite and sepiolite, and contains carbonate intercalations near the top. A statistical treatment of the mineralogical and chemical composition data from 120 samples, using principal factor analysis, suggests that: (a) illite and smectite are detrital in origin; (b) palygorskite was formed by transformation of illite and smectite involving reaction with Mg; and (c) sepiolite was a neoformation product favoured by evaporation of silica- and Mg-bearing waters.

The Oost Interest Inventory was administered to 69 English, 126 Economy and 110 Chemistry students during 1993, to obtain information on construct validity. Except for the area Physical Activities all the differences between the means were significant. Product-moment correlations for related areas across instruments ranged from .15 to .66 and for unrelated areas from .03 to .14. Principal factor analysis with varimax rotation yielded three factors, namely, Arts, Science and Economy–Numbers.
