Hypothetical Structure

A sample of 202 Kuwaiti college students (63 men and 139 women; Mage = 21.6 yr., SD = 2.4) responded to the Thalbourne, et al.'s Manic-Depressiveness Scale. In a factor analysis with a varimax rotation, 14 of 18 items had significant loadings (>.3) on the first factor, including 8 items of the original depression scale. 6 items significantly loaded on the second factor, including 3 items of the original mania scale. This did not match the hypothetical structure of the scale.

In a sample of 503 American college students, the correlational matrix (18 × 18) of the Thalbourne, et al. Manic-Depressiveness Scale (1994) was subjected to exploratory factor analysis with a varimax rotation, which showed 13 items had the correct assignment to one of the scales (six for depression and seven for mania).

A scale devised to measure executive personal money management was examined for its factorial structure using 138 college students. On the whole, the factor analysis confirmed the subscale structure of the scale, but the Planning subscale appeared to consist of two distinct components, investment behavior and saving behavior.

Death Depression

The aims were to estimate the psychometric properties of the Spanish form of the Death Depression Scale and to compare these with those of other versions of the scale. The Death Depression Scale was administered to a sample of 218 Spanish student nurses, together with Templer's Death Anxiety Scale and measures of general depression and anxiety. The Cronbach coefficient α was 83, and a 4-wk. test-retest correlation was .87. The correlations with scores on other tests were similar to those obtained in former studies. After applying a principal components factor analysis with varimax rotation, four factors with eigenvalues greater than one were identified. These factors were labeled Death Sadness, Death Finality, Meaninglessness of Life, and Feeling of Loss. Generally speaking, the results favour consideration of the Death Depression Scale as a valid and reliable means of assessment among Spanish-speaking individuals.

Following earlier theoretical suggestions by Rokeach, this paper investigated the factorial structure of the Rokeach Dogmatism Scale and the Gough-Sanford Rigidity Scale both individually and together to determine if they could be shown to tap empirically different aspects of personality. In addition with the sample of 1074, part sample analyses were done to examine the stability of factor-analytic results. Using orthogonal varimax rotation, a clear separation of Dogmatism and Rigidity was shown, in support of Rokeach's theory; the individual analyses yielded insight into the nature of the two tests' content.

OBJECTIVES: The Schedule for the Assessment of Insight - Expanded Version consists of 11 items that encompass: awareness of having a mental illness, ability to rename psychotic phenomena as abnormal, and compliance with treatment. The objective of the study was to evaluate the inter-rater reliability and to study the factorial structure of the Brazilian version of the instrument. METHOD: The Brazilian version of the Schedule for the Assessment of Insight - Expanded Version was used for the assessment of insight of 109 psychotic inpatients, 60 of whom had the interview tape-recorded in order to be scored by an independent evaluator. Intraclass correlation coefficient (ICC) was adopted as the inter-rater reliability coefficient. In the factor analysis, principal components analysis and Varimax rotation were adopted. RESULTS: Inter-rater reliability coefficients from good to excellent were found for the individual items of the Schedule for the Assessment of Insight - Expanded Version with ICC values ranging from 0.54 to 0.82. Regarding the total score, inter-rater reliability was excellent, with ICC = 0.90. A factorial structure similar to the one obtained by the original version of the Schedule for the Assessment of Insight - Expanded Version was found, with 3 factors accounting for 71.72% of variance. CONCLUSION: In the Brazilian context, the Schedule for the Assessment of Insight - Expanded Version presented good inter-rater reliability and factorial structure compatible to the insight dimensions that are intended to be evaluated.

The present study is aimed at examining the level of death anxiety and the sex-related differences among old-aged Iranian individuals sample to compare the old-aged persons with young college students and to explore the psychometric properties of the Arabic Scale of Death Anxiety (ASDA) factors in old-aged sample. A sample of 146 volunteer Iranian individuals took part in the study. The mean ages were 68.58 (SD = 7.10), men 68.81 (SD = 7.44) and women 68.28 (SD = 6.76), respectively. The mean score of the ASDA was 51.09 (SD = 20.19). Cronbach’s alpha of the ASDA was found to be high (0.94); and Spearman-Brown coefficient was 0.92. Women had a significantly higher mean total score on the ASDA. Old-aged individuals had a significantly higher mean ASDA total score than younger college students (M age = 25.77). The factor analysis of the ASDA items yielded three factors accounting for 67.88% of the total variance labeled (F1) fear of dead people and tombs; (F2) fear of lethal disease and postmortem events; and (F3) death fear. These factors were highly replicable with previous factors extracted from a middle-aged Kuwaiti sample. On the basis of the present results, there are the following three general conclusions: death anxiety is not significantly correlated with age; the sex-related differences on death anxiety are striking in the Iranian samples; and the ASDA has a highly replicable factor structure among two Iranian and Arab countries.

The Center for Epidemiological Studies-Depression Scale is one of the most popular instruments for survey work with the general population. A 1993 study by Thorson and Powell reported a 5-factor solution. The present study was undertaken to replicate these findings; however, factor analysis with varimax rotation based on the responses of 187 students yielded 4 factors of depressed affect, somatic disturbance, positive affect, and interpersonal difficulties. Although these data do not replicate the 5-factor work of Thorson and Powell, they do largely confirm the previous research.

Scholarly Attention

Research on the topic of loneliness has begun to attract scholarly attention. The study reported here examined the dimensions of loneliness tapped by the often used UCLA Loneliness Scale which has previously been reported as a global, unidimensional, measure of the phenomenon. Data from 493 college students were subjected to factor analysis which yielded three factors. These factors were labeled and explained in terms of loneliness regarding Intimate Others, Social Others, and a feeling of a lack of Belonging and Affiliation. Demographic and attribute data were compared for each of the three dimensions. Additional research replicating this study on non-student populations is required to determine the validity of the present results for the general population.

Components Analysis

Factor analysis was performed on the Beck Depression Inventory with a university sample to examine its potential multidimensionality. A principal components analysis with an oblimin and varimax rotation produced a two-factor solution. These factors were labeled Cognitive–Affective and Physiological and accounted for approximately 39% of the common variance. This finding is consistent with multidimensionality of the inventory and with a similar study of college students. The commonalities of the two studies suggest the reliability (internal consistency) of the Cognitive-Affective and Physiological constructs among “minimally” depressed university samples.
